    Anaemia is frequent in cancer and may increase tumour hypoxia that stimulates angiogenesis. However, erythropoietin is a hypoxia-inducible stimulator of erythropoiesis which seems to improve quality of life in cancer patients. Two recent phase III randomized studies showed negative results using erythropoietin in head and neck cancer patients and in metastatic breast cancer patients with impaired specific survival. In vitro and in vivo experiments have provided erythropoietin-receptor expression in endothelial cancer cells including malignant tumours of the breast, prostate, cervix, lung, head and neck, ovary, melanoma, stomach, gut, kidney etc. Biologic effect of erythropoietin and its receptor linkage induces proliferation of human breast cancer and angiogenesis and may limit anti-tumour effect of cancer treatment, in part, by tumour vascularization improvement. In addition, the use of exogenous erythropoietin could be able to favour tumour progression by improving tumour oxygenation and nutriment supply. If erythropoietin receptor were functional in human cancer. the assessment of erythropoietin receptor expression on tumour cell may help to select patients benefiting from exogenous erythropoietin. However. the relationship between erythropoietin receptor expression, tumour growth and exogenous erythropoietin. requires more studies. The results of recent clinical trials suggest that using erythropoietin should be avoided in non-anemic patients and discussed in patients receiving curative therapy. (authors)

  2. Care of patients undergoing external radiotherapy

    International Nuclear Information System (INIS)

    The anxiety and associated depression suffered by most patients undergoing radiotherapy is discussed and the possibilities open to the nurse to encourage and reassure patients thus facilitating physical care are considered. The general symptoms of anorexia, nausea, tiredness, skin problems, alopecia, bonemarrow depresssion and rapid tumour destruction are described and nursing care prescribed. The side-effects which may occur following radiation of the brain, head and neck region, eyes, oesophagus, lung, abdomen, pelvis, bones, skin, spine, and spinal cord are considered from the nursing standpoint. The specialised subject of radiotherapy in children is discussed briefly. (U.K.)

  3. Effects of radiotherapy on the chemical constituents of blood in patients undergoing renal dialysis

    International Nuclear Information System (INIS)

    Changes in the chemical constituents of blood during radiotherapy in three patients who had undergone renal dialysis were examined. Serum blood urea nitrogen and potassium levels tended to rise during radiotherapy. In one patient, the serum potassium level exceeded 6.0 mEq/l, necessitating changes in treatment. Patients undergoing renal dialysis should be carefully monitored during radiotherapy, and management from the viewpoints of radiotherapy, renal dialysis, and diet control is necessary. (author)

  5. Changes in cell-mediated immunity in patients undergoing radiotherapy

    International Nuclear Information System (INIS)

    The cell-mediated immune status of 147 patients who received radiotherapy was evaluated using in vitro tests (PHA, E-rosette, and spontaneous blastogenesis) both before and 6 weeks after the end of radiation. All patients have verified malignancies, involving the bronchus in 29 cases, breast in 28, female genital system in 26, head and neck in 20 and bladder in 15. Patients suffering from bronchogenic carcinomas or malignancies of the head and neck showed a relative high degree of immune suppression. Our findings indicate a trend towards some improvement in PHA reactivity, as well as in the percentage of E-rosette-forming cells after treatment, which is more noticeable in patients with pelvic or breast tumors. A relationship seems to exist between the tumor load and the immune status, which reverts to a normal pattern when the former is extinguished. Moreover, patients with poor clinical response display a profoundly depressed level of immune status without any improvement after treatment

  6. Problems and challenges in care for children undergoing radiotherapy- A research paper

    The importance and variability of pre-operative anaemia in cardiac surgical patients across the UK is not known, and there is debate about its association with patient outcomes. The Association of Cardiothoracic Anaesthetists carried out its first national audit on anaemia and transfusion, and analysed data from 19,033 patients operated on in 12 cardiac surgical centres between 2010 and 2012; 5895 (31%) had pre-operative anaemia. Centre-specific prevalence of anaemia varied from 23% to 45%; anaemia was associated with older patients, diabetes and surgical risk (EuroSCORE). Nevertheless, controlling for these factors, regional variation remained an independent effect (p treatment before cardiac surgery is required; these data will assist in designing such trials.

  8. A national survey of supportive practices for patients undergoing radiotherapy for oral cancers

    International Nuclear Information System (INIS)

    Purpose: Xerostomia and mucositis are two of the main radiation induced toxicities experienced by patients undergoing radiotherapy to the oral cavity. These toxicities can lead to significant weight loss with the potential to cause complications with radiotherapy treatment. Literature has shown that nutritional intervention can help to minimise these side effects. The aim of the survey was to explore current practice across the UK in nutritional intervention for these patients. Method: Postal questionnaires were sent to all 63 radiotherapy departments in the UK in November 2009. Results: 29 responses (43%) were received. 90% (n = 26) of the departments used 3D-Conformal radiotherapy (3D-CRT) as the main technique for treatment of these patients, with 48% (n = 14) of departments having implemented Intensity modulated radiotherapy (IMRT). All departments referred their patients to a dietician. 93% (n = 27) of departments placed percutaneous endoscopic gastrostomy or radiologically-inserted gastrostomy tubes. 55% (n = 16) departments administered nasogastric tubes. Conclusion: This survey verified many common practices regarding dietary care and advice, some variation was evident in the use of feeding tubes. All responding centres referred patients to a dietician with the aim to maintain nutritional status and prevent weight loss that could contribute to uncertainty in treatment setup. This survey also demonstrated that since Macknelly and Day's (2009) study, a greater number of centres have implemented IMRT for patients undergoing radiotherapy to the head and neck. Although IMRT has been shown to reduce xerostomia, this audit found no changes in the dietary care and advice given to these patients

    Approximately 300 children ages 0 to 18 are diagnosed with cancer in Sweden every year, and 80 to 90 of them undergo radiotherapy treatment. The aim was to describe children’s experiences of preparing for and undergoing radiotherapy, and furthermore to describe children’s suggestions for improvement. Thirteen children between the ages of 5 and 15 with various cancer diagnoses were interviewed. Data was analyzed using qualitative content analysis. The findings revealed five categories: positive and negative experiences with hospital stays and practical arrangements; age-appropriate information, communication, and guidance to various degrees; struggle with emotions; use of distraction and other suitable coping strategies; and children’s suggestions for improvement during radiotherapy. An overarching theme emerged: “It is tough and tiring but it works”. Some key areas were: explanatory visits, the need for information and communication, being afraid, discomfort and suffering, the need for media distraction, dealing with emotions, and the need for support. A systematic, family-centered preparation program could possible help families prepare and individualized distraction during radiotherapy could contribute to reducing distress. Further studies with interventions could clarify successful programs. PMID:27055258

    Malnutrition occurs frequently in patients with cancer. Indeed, a variety of nutritional and tumor-related factors must be taken into account in these patients. Recognizing this relationship, we aimed to prospectively evaluate the risk factors that influence weight loss in patients undergoing radiotherapy with oral nutritional supplementation and dietetic counseling. Weight loss of 74 patients during radiotherapy and 1 month after treatment was analyzed. Parameters such as age, gender, tumor location, tumor stage, Eastern Cooperative Oncology Group performance status (ECOG PS) score, and the use of chemotherapy were analyzed to evaluate their influence on weight loss. All patients underwent oral nutritional supplementation and dietetic counseling. Forty-six (65.7%) patients lost weight, with a mean weight loss of (4.73 ± 3.91) kg, during radiotherapy. At 1 month after treatment, 45 (66.2%) patients lost weight, presenting a mean weight loss of (4.96 ± 4.04) kg, corresponding to a (6.84 ± 5.24)% net reduction from their baseline weight. Head and neck cancer patients had a mean weight loss of (3.25 ± 5.30) kg, whereas the remaining patients had a mean weight loss of (0.64 ± 2.39) kg (P=0.028) during radiotherapy. In the multivariate analysis, the head and neck tumor location (P = 0.005), use of chemotherapy (P = 0.011), and ECOG PS score of 2-3 (P = 0.026) were considered independent risk factors. Nutritional status and parameters, such as tumor location (especially the head and neck), the use of chemotherapy, and the ECOG PS score, should be evaluated before radiotherapy because these factors can influence weight loss during radiotherapy and 1 month after treatment.

    Full Text Available Introduction: Cancer is the second leading cause of death worldwide and the radiotherapy is one of the types of cancer treatment. It is calculated that more than half of all people with cancer will undergoing radiotherapy as at least part of their cancer treatment. Purpose: The purpose of the present study was the description of role of nurse in radiation oncology. Method: Literature review of the relevant articles in the databases pubmed and scopus was conducted, but also were used articles of international professional nursing organizations Results: The radiation oncology nursing role is multidimensional and is focused in patient assessment, patient and family education, support and counselling, physical care of patient and in the research. The patient’s care is mainly focused in the conducting of suitable nursing interventions that will alleviate the patient from the side effects of radiotherapy. Conclusions: The nurses should be known the technologies that are used in the radiotherapy so that they are enable to educate their patients and provide qualitative nursing care. Changes in the health care environment and changes in treatment and technology continue to drive cancer care. So nurses should collaborate and communicate with other members of interdisciplinary team and incorporate evidence into practice

    Background and results: anemia is a well-known risk factor for decreased local control and survival in patients undergoing curative radiotherapy. There is clear evidence from recent clinical investigations that anemia is an independent risk factor and hemoglobin (Hb) levels during radiotherapy are important (and not pretreatment Hb levels). The most likely explanation for the prognostic impact is the association with tumor hypoxia. An ''optimal'' Hb range with regard to tumor oxygenation seems to exist, and Hb levels < 11 g/dl and > {proportional_to}15 g/dl impair tumor oxygenation but have (over a broader range) no significant impact on normal tissue oxygenation. There is some evidence from retrospective and prospective studies that the response to radiotherapy and the prognosis, especially in cervical cancers, might be improved if the Hb levels during radiotherapy can be maintained in the optimal range, either by transfusions or by erythropoietin. The effect of any antianemic therapy should be analyzed according to whether or not treatment was successful with regard to achieving optimal Hb levels during irradiation. Erythropoietin is probably more effective in steadily increasing and stabilizing Hb levels, but bears the risk of overcorrection of Hb levels. The clinical relevance of erythropoietin receptors on tumor cells remains questionable. Conclusions: treatment of anemia with the objective of improving local control and survival in radiotherapy patients is probably more difficult and sophisticated than coping with symptoms of anemia or improving quality of life. Nevertheless, the potential of antianemic treatment is high on the basis of experimental and clinical data, and further clinical trials are warranted. (orig.)

    Hypothesis This study examines moderators and mediators of a yoga intervention targeting quality-of-life (QOL) outcomes in women with breast cancer receiving radiotherapy.Methods Women undergoing 6 weeks of radiotherapy were randomized to a yoga (YG; n = 53) or stretching (ST; n = 56) intervention or a waitlist control group (WL; n = 54). Depressive symptoms and sleep disturbances were measured at baseline. Mediator (posttraumatic stress symptoms, benefit finding, and cortisol slope) and outcome (36-item Short Form [SF]-36 mental and physical component scales [MCS and PCS]) variables were assessed at baseline, end-of-treatment, and 1-, 3-, and 6-months posttreatment. Results Baseline depressive symptoms (P = .03) and sleep disturbances (P stress symptoms and cortisol slope did not mediate treatment effect on QOL. Conclusion Yoga may provide the greatest mental-health-related QOL benefits for those experiencing pre-radiotherapy sleep disturbance and depressive symptoms. Yoga may improve physical-health-related QOL by increasing ability to find benefit in the cancer experience. PMID:26867802

  15. Daily electronic portal imaging of implanted gold seed fiducials in patients undergoing radiotherapy after radical prostatectomy

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to measure interfraction prostate bed motion, setup error, and total positioning error in 10 consecutive patients undergoing postprostatectomy radiotherapy. Methods and Materials: Daily image-guided target localization and alignment using electronic portal imaging of gold seed fiducials implanted into the prostate bed under transrectal ultrasound guidance was used in 10 patients undergoing adjuvant or salvage radiotherapy after prostatectomy. Prostate bed motion, setup error, and total positioning error were measured by analysis of gold seed fiducial location on the daily electronic portal images compared with the digitally reconstructed radiographs from the treatment-planning CT. Results: Mean (± standard deviation) prostate bed motion was 0.3 ± 0.9 mm, 0.4 ± 2.4 mm, and -1.1 ± 2.1 mm in the left-right (LR), superior-inferior (SI), and anterior-posterior (AP) axes, respectively. Mean set-up error was 0.1 ± 4.5 mm, 1.1 ± 3.9 mm, and -0.2 ± 5.1 mm in the LR, SI, and AP axes, respectively. Mean total positioning error was 0.2 ± 4.5 mm, 1.2 ± 5.1 mm, and -0.3 ± 4.5 mm in the LR, SI, and AP axes, respectively. Total positioning errors >5 mm occurred in 14.1%, 38.7%, and 28.2% of all fractions in the LR, SI, and AP axes, respectively. There was no significant migration of the gold marker seeds. Conclusions: This study validates the use of daily image-guided target localization and alignment using electronic portal imaging of implanted gold seed fiducials as a valuable method to correct for interfraction target motion and to improve precision in the delivery of postprostatectomy radiotherapy

  16. The influence of MRI scan position on patients with oropharyngeal cancer undergoing radical radiotherapy

    International Nuclear Information System (INIS)

    The purpose of this study was to demonstrate how magnetic resonance imaging (MRI) patient position protocols influence registration quality in patients with oropharyngeal cancer undergoing radical radiotherapy and the consequences for gross tumour volume (GTV) definition and radiotherapy planning. Twenty-two oropharyngeal patients underwent a computed tomography (CT), a diagnostic MRI (MRID) and an MRI in the radiotherapy position within an immobilization mask (MRIRT). Clinicians delineated the GTV on the CT viewing the MRID separately (GTVC); on the CT registered to MRID (GTVD) and on the CT registered to MRIRT (GTVRT). Planning target volumes (PTVs) were denoted similarly. Registration quality was assessed by measuring disparity between structures in the three set-ups. Volumetric modulated arc therapy (VMAT) radiotherapy planning was performed for PTVC, PTVD and PTVRT. To determine the dose received by the reference PTVRT, we optimized for PTVC and PTVD while calculating the dose to PTVRT. Statistical significance was determined using the two-tailed Mann–Whitney or two-tailed paired student t-tests. A significant improvement in registration accuracy was found between CT and MRIRT versus the MRID measuring distances from the centre of structures (geometric mean error of 2.2 mm versus 6.6 mm). The mean GTVC (44.1 cm3) was significantly larger than GTVD (33.7 cm3, p value = 0.027) or GTVRT (30.5 cm3, p value = 0.014). When optimizing the VMAT plans for PTVC and investigating the mean dose to PTVRT neither the dose to 99% (58.8%) nor 95% of the PTV (84.7%) were found to meet the required clinical dose constraints of 90% and 95% respectively. Similarly, when optimizing for PTVD the mean dose to PTVRT did not meet clinical dose constraints for 99% (14.9%) nor 95% of the PTV (66.2%). Only by optimizing for PTVRT were all clinical dose constraints achieved. When oropharyngeal patients MRI scans are performed in the radiotherapy position there are significant

  17. Anti-emetic effect of granisetron in patients undergoing cranial and craniospinal radiotherapy

    International Nuclear Information System (INIS)

    Approximately 30-59% of patients undergoing cranial or craniospinal radiotherapy experience nausea and/or vomiting. Here, we evaluated the effectiveness of granisetron for controlling emesis in patients treated with cranial or craniospinal radiotherapy. Between December 2011 and January 2013, 34 patients (19 males, 15 females; age range, 3-80 years) received cranial or craniospinal radiotherapy at our department. All but one male patient, who developed meningitis during the irradiation period were enrolled in this retrospective study. Patients who experienced irradiation-induced vomiting (grade 1) or nausea (grade 2) were treated with granisetron as a rescue anti-emetic. Episodes were graded as no vomiting, no nausea, no anti-emetic; no vomiting, nausea, no anti-emetic; no vomiting, nausea with anti-emetic; and vomiting. Of the 9 patients who underwent whole-brain or whole neural-axis irradiation, 5 (55.6%) experienced grade 2 nausea or vomiting. Two of 6 patients (33.3%) treated with whole ventricle irradiation experienced grade 2 nausea or vomiting. Three of 18 patients (16.7%) who underwent local-field irradiation experienced grade 2 nausea or vomiting. Patients who underwent wide-field irradiation experienced nausea, vomiting, and anorexia (p<0.05). Complete response (no vomiting, no additional rescue anti-emetic, and no nausea) was observed in 5 of 9 patients treated with granisetron. Four of 9 patients (44.4%) treated with granisetron experienced constipation (grade 1 or 2); its administration had no major adverse effects in our study population. Rescue therapy with granisetron is safe and effective to treat nausea and vomiting in patients subjected to cranial or craniospinal irradiation. (author)

  18. Clinical Effect of Human Papillomavirus Genotypes in Patients With Cervical Cancer Undergoing Primary Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To study the prognostic value of the human papillomavirus (HPV) genotypes in cervical cancer patients undergoing radiotherapy. Patients and Methods: A total of 1,010 patients with cervical cancer after radiotherapy between 1993 and 2000 were eligible for this study. The HPV genotypes were determined by a genechip, which detects 38 types of HPV. The patient characteristics and treatment outcomes were analyzed using the Cox regression hazard model and classification and regression tree decision tree method. Results: A total of 25 genotypes of HPV were detected in 992 specimens (98.2%). The leading 8 types were HPV16, 58, 18, 33, 52, 39, 31, and 45. These types belong to two high-risk HPV species: alpha-7 (HPV18, 39, 45) and alpha-9 (HPV16, 31, 33, 52, 58). Three HPV-based risk groups, which were independent of established prognostic factors, such as International Federation of Gynecology and Obstetrics stage, age, pathologic features, squamous cell carcinoma antigen, and lymph node metastasis, were associated with the survival outcomes. The high-risk group consisted of the patients without HPV infection or the ones infected with the alpha-7 species only. Patients co-infected with the alpha-7 and alpha-9 species belonged to the medium-risk group, and the others were included in the low-risk group. Conclusion: The results of the present study have confirmed the prognostic value of HPV genotypes in cervical cancer treated with radiotherapy. The different effect of the alpha-7 and alpha-9 species on the radiation response deserves additional exploration.

  19. Prospective Study of Psychosocial Distress Among Patients Undergoing Radiotherapy for Head and Neck Cancer

    International Nuclear Information System (INIS)

    Purpose: To determine the prevalence of psychosocial distress among patients undergoing radiotherapy (RT) for head and neck cancer and to examine the association between depression and anxiety and demographic and medical variables. Methods and Materials: A total of 40 patients (25 men and 15 women) with nonmetastatic head and neck cancer were enrolled in this prospective study and underwent RT administered with definitive (24 patients) or postoperative (16 patients) intent. Twenty patients (50%) received concurrent chemotherapy. All patients completed the Hospital Anxiety and Depression Scale and Beck Depression Inventory-II instrument before RT, on the last day of RT, and at the first follow-up visit. The effect of patient-, tumor-, and treatment-related factors on psychosocial distress was analyzed. Results: The prevalence of mild to severe pre-RT depression was 58% and 45% using the Hospital Anxiety and Depression Scale-D and Beck Depression Inventory-II scale, respectively. The prevalence of severe pre-RT anxiety was 7%. The depression levels, as determined by the Hospital Anxiety and Depression Scale and Beck Depression Inventory-II instrument increased significantly during RT and remained elevated at the first follow-up visit (p < 0.001 for both). The variables that were significantly associated with post-RT depression included a greater pre-RT depression level, employment status (working at enrollment), younger age (<55 years), single marital status, and living alone (p < 0.05, for all). Conclusion: The results of our study have shown that an alarming number of patients undergoing RT for head and neck cancer have symptoms suggestive of psychosocial distress even before beginning treatment. This proportion increases significantly during RT. Studies investigating the role of antidepressants and/or psychiatric counseling might be warranted in the future

    OBJECTIVE To examine fatigue and quality of life (QOL) in breast cancer patients undergoing chemotherapy or radiotherapy.METHODS A self-report survey derived from the Chinese version of Brief Fatigue Inventory, the Functional Assessment of Chronic Illness Therapy for Breast Cancer, and the Medical Outcomes Study Social Support Survey. Descriptive statistics was used to examine the intensity of fatigue and the prevalence of severe fatigue. Multivariate analysis of variance was used to determine factors that affect the five domains of QOL among the participants.RESULTS The majority of the participants (n = 261) perceived a mild level of fatigue, but 35.6% of them suffered severe fatigue. Fatigue had a significantly negative association with all domains of QOL except social/family wellbeing. The participants who were receiving chemotherapy, undergoing curative treatment and having inadequate social support were more likely to have poorer QOL in all five domains (after adjustment for age).CONCLUSION Although the majority of the participants experienced a mild level of fatigue, there was a substantial group of breast cancer patients who perceived their fatigue as severe. The findings of this study showed that fatigue had a detrimental effect on the various aspects of the participants'QOL. Demographic and clinical characteristics of breast cancer patients who were at risk of getting poorer QOL were identified. The results of the study demonstrate that we should enhance healthcare professionals' awareness of the importance of symptom assessment, and provide them with information for planning effective symptom-management strategies among this study population.

    Full Text Available Basing on alanine solid state/electron paramagnetic resonance (EPR dosimetry, a supplementary method of cumulatively recording the therapeutic dose received by ocular cancer patients undergoing fractionated proton radiotherapy is proposed. By applying alanine dosimetry during the delivery of consecutive fractions, the dose received within each fraction can be read out by EPR spectrometry and a final permanent cumulative record of the total dose delivered obtained. The dose response of the alanine detector was found to be practically independent on its position within the extended proton Bragg peak region. Dose measurements based on entrance dose recorded in proton beams individually formed for each patient are presented. The described method will be applied as a complementary Quality Assurance procedure for patients undergoing proton radiotherapy at the Institute of Nuclear Physics, Polish Academy of Sciences, Krakow, Poland (IFJ PAN.

  3. Proposed Rectal Dose Constraints for Patients Undergoing Definitive Whole Pelvic Radiotherapy for Clinically Localized Prostate Cancer

    International Nuclear Information System (INIS)

    Purpose: Although several institutions have reported rectal dose constraints according to threshold toxicity, the plethora of trials has resulted in multiple, confusing dose-volume histogram recommendations. A set of standardized, literature-based constraints for patients undergoing whole pelvic radiotherapy (RT) for prostate cancer would help guide the practice of prostate RT. The purpose of this study was to develop these constraints, demonstrate that they are achievable, and assess the corresponding rectal toxicity. Methods and Materials: An extensive literature search identified eight key studies relating dose-volume histogram data to rectal toxicity. A correction factor was developed to address differences in the anatomic definition of the rectum across studies. The dose-volume histogram constraints recommended by each study were combined to generate the constraints. The data from all patients treated with definitive intensity-modulated RT were then compared against these constraints. Acute rectal toxicity was assessed. Results: A continuous, proposed rectal dose-constraint curve was generated. Intensity-modulated RT not only met this constraint curve, but also was able to achieve at least 30-40% lower dose to the rectum. The preliminary clinical results were also positive: 50% of patients reported no acute bowel toxicity, 33% reported Grade 1 toxicity, and 17% reported Grade 2 toxicity. No patients reported Grade 3-4 acute rectal toxicity. Conclusions: In this study, we developed a set of proposed rectal dose constraints. This allowed for volumetric assessment of the dose-volume relationship compared with single dose-volume histogram points. Additional research will be performed to validate this threshold as a class solution for rectal dose constraints

    Pilocytic astrocytoma, the most common glioma of childhood, is considered a clinically benign tumour. Malignant transformation of this tumour is rare and thought to occur almost exclusively in the setting of prior radiotherapy. We describe a patient with mixed pilocytic and gemistocytic astrocytoma which transformed into a glioblastoma multiforme, leading to rapid deterioration and death of the patient, without prior radiotherapy.

    Background and purpose: Anorexia is a common problem in cancer patients who receive radiotherapy. In this current study, we attempt to determine the effect of megestrol acetate and prepulsid on appetite and nutritional improvement in patients with head and neck cancers undergoing radiotherapy. Materials and Methods: One hundred twenty-nine consecutive patients with head and neck cancers treated between July 1993 and June 1994 were prospectively randomized to receive either megestrol acetate, 40 mg qid (megace group), prepulsid, 5 mg tid (cisapride group), or a placebo treatment (control group) during radiotherapy. Before radiotherapy, body weight (kg), appetite score, performance status, biochemical parameters and hematological parameters were evaluated, and the above-noted clinical and biochemical parameters were assessed and recorded every other week. All patients received 6- 10 MV X-rays or Co-60 γ-ray to head and neck region for a full course of radiotherapy, 61.2-75.6 Gy/7-9 weeks. Results: Forty-eight patients were enrolled in the megace group, 41 patients in the cisapride group, and 40 patients in the control group. At the 2nd, 4th, 6th and 8th week, as the radiation dose escalated, the megace group had significantly less body weight loss than did the cisapride and control groups (P = 0.045, 0.024, 0.006, 0.003, respectively). The appetite scores of the megace group were significantly higher than those of the cisapride and control groups (P 0.0001). However, there were no statistically significant differences in the change of albumin level among these three groups at the 2nd, 4th, 6th and 8th week (P > 0.05, respectively). Conclusions: Megestrol acetate can significantly decrease the degree of body weight loss, and can prevent the deterioration of appetite in patients with head and neck cancers receiving radiotherapy. However, prepulsid lacks the above-mentioned clinical benefits

  6. Prognostic factors, patterns of recurrence and toxicity for patients with esophageal cancer undergoing definitive radiotherapy or chemo-radiotherapy

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the effectiveness and tolerability of definitive chemo-radiation or radiotherapy alone in patients with esophageal cancer. We retrospectively analyzed the medical records of n = 238 patients with squamous cell carcinoma or adenocarcinoma of the esophagus treated with definitive radiotherapy with or without concomitant chemotherapy at our institution between 2000 and 2012. Patients of all stages were included to represent actual clinical routine. We performed univariate and multivariate analysis to identify prognostic factors for overall survival (OS) and progression-free survival (PFS). Moreover, treatment-related toxicity and patterns of recurrence were assessed. Patients received either chemo-radiation (64%), radiotherapy plus cetuximab (10%) or radiotherapy alone (26%). In 69%, a boost was applied, resulting in a median cumulative dose of 55.8 Gy; the remaining 31% received a median total dose of 50 Gy. For the entire cohort, the median OS and PFS were 15.0 and 11.0 months, respectively. In multivariate analysis, important prognostic factors for OS and PFS were T stage (OS: P = 0.005; PFS: P = 0.006), M stage (OS: P = 0.015; PFS: P = 0.003), concomitant chemotherapy (P < 0.001) and radiation doses of >55 Gy (OS: P = 0.019; PFS: P = 0.022). Recurrences occurred predominantly as local in-field relapse or distant metastases. Toxicity was dominated by nutritional impairment (12.6% with G3/4 dysphagia) and chemo-associated side effects. Definitive chemo-radiation in patients with esophageal cancer results in survival rates comparable with surgical treatment approaches. However, local and distant recurrence considerably restrict prognosis. Further advances in radio-oncological treatment strategies are necessary for improving outcome. (author)

  7. Cytogenetic damage in circulating lymphocytes and buccal mucosa cells of head-and-neck cancer patients undergoing radiotherapy

    International Nuclear Information System (INIS)

    This study evaluated cytogenetic damage by measuring the frequency of micronucleated cells (MNC) in peripheral blood and buccal mucosa of head-and-neck cancer patients undergoing radiotherapy. MNC frequencies were assessed in 31 patients before, during, and after radiotherapy, and in 17 healthy controls matched for gender, age, and smoking habits. Results showed no statistically significant difference between patients and controls prior to radiotherapy in cytokinesis-blocked lymphocytes or buccal mucosa cells. During treatment, increased MNC frequencies were observed in both cell types. Micronucleated lymphocyte levels remained high in samples collected 30 to 140 days after the end of treatment, while MNC frequency in buccal mucosa decreased to values statistically similar to baseline values. There is controversy over the effects of age, smoking habit, tumor stage, and/or metastasis on MNC frequency. However, increased frequency of micronucleated buccal mucosa cells was seen in patients under 60 years old and in those with tumors >4 cm. In conclusion, the data show that radiotherapy has a potent clastogenic effect in circulating lymphocytes and buccal mucosa cells of head-and-neck cancer patients, and that the baseline MNC frequency in these two tissues is not a sensitive marker for head-and neck neoplasm.

    Full Text Available Nutritional anaemia due to iron and folate deficiency is a major global Public Health problem. South Asia ranks among the regions, which have the highest prevalence of anaemia in the world and India perhaps has the highest prevalence of anaemia among the South Asian countries. Prevalence of anaemia is higher among pregnant women and preschool children. Even among higher income educated segments of population about 50% of children, adolescent girls and pregnant women are anaemic. Inadequate dietary iron, folate intake and poor bioavailability of dietary iron from the fibre, phytate rich Indian diets are the major factors responsible for high prevalence of anaemia. Increased requirement of iron during growth and pregnancy and chronic blood loss contribute to higher prevalence in specific groups. Many times anaemia is directly or indirectly responsible for maternal deaths. Early detection and effective management of anaemia in pregnancy can contribute substantially to reduction in maternal mortality. Maternal anaemia is associated with poor intrauterine growth and increased risk of preterm births and low birth weight rates. This in turn results in higher perinatal morbidity and mortality, and higher infant mortality rate. Maternal anaemia contributes to intergenerational cycle of poor growth in the offspring. Early detection and effective management of anaemia in preganancy can lead to substantial reduction in under nutrition in childhood, adolescence and improvement in adult height.

    Full Text Available Abstract Background Recently published results of quality of life (QoL studies indicated different outcomes of palliative radiotherapy for brain metastases. This prospective multi-center QoL study of patients with brain metastases was designed to investigate which QoL domains improve or worsen after palliative radiotherapy and which might provide prognostic information. Methods From 01/2007-01/2009, n=151 patients with previously untreated brain metastases were recruited at 14 centers in Germany and Austria. Most patients (82 % received whole-brain radiotherapy. QoL was measured with the EORTC-QLQ-C15-PAL and brain module BN20 before the start of radiotherapy and after 3 months. Results At 3 months, 88/142 (62 % survived. Nine patients were not able to be followed up. 62 patients (70.5 % of 3-month survivors completed the second set of questionnaires. Three months after the start of radiotherapy QoL deteriorated significantly in the areas of global QoL, physical function, fatigue, nausea, pain, appetite loss, hair loss, drowsiness, motor dysfunction, communication deficit and weakness of legs. Although the use of corticosteroid at 3 months could be reduced compared to pre-treatment (63 % vs. 37 %, the score for headaches remained stable. Initial QoL at the start of treatment was better in those alive than in those deceased at 3 months, significantly for physical function, motor dysfunction and the symptom scales fatigue, pain, appetite loss and weakness of legs. In a multivariate model, lower Karnofsky performance score, higher age and higher pain ratings before radiotherapy were prognostic of 3-month survival.

    Full Text Available The aim of this study was to evaluate the influence of chlorhexidine gluconate, sodium fluoride and sodium iodine on mutans streptococci counts in saliva of irradiated patients. MATERIAL AND METHODS: Forty-five patients were separated into three experimental groups and received chlorhexidine (0.12%, sodium fluoride (0.5% or sodium iodine (2%, which were used daily during radiotherapy and for 6 months after the conclusion of the treatment. In addition, a fourth group, composed by 15 additional oncologic patients, who did not receive the mouthwash or initial dental treatment, constituted the control group. Clinical evaluations were performed in the first visit to dental clinic, after initial dental treatment, immediately before radiotherapy, after radiotherapy and 30, 60, 90 days and 6 months after the conclusion of radiotherapy. After clinical examinations, samples of saliva were inoculated on SB20 selective agar and incubated under anaerobiosis, at 37ºC for 48 h. Total mutans streptococci counts were also evaluated by using real-time PCR, through TaqMan system, with specific primers and probes for S. mutans and S. sobrinus. RESULTS: All preventive protocols were able to reduce significantly mutans streptococci counts, but chlorhexidine gluconate was the most effective, and induced a significant amelioration of radiotherapy side effects, such as mucositis and candidosis. CONCLUSION: These results highlights the importance of the initial dental treatment for patients who will be subjected to radiotherapy for head and neck cancer treatment.

    In the elderly, even mild anaemia leads to significantly decreased quality of life and reduced survival rate. Therefore even mild anaemias should be worked up especially in the elderly. More than 75 % of all anaemias have a specific and treatable cause.Differential diagnosis of anaemia in the elderly is much more challenging compared to the differential diagnosis in younger patients: in older patients often more than one dysfunction is responsible for the anaemia simultaneously. Many routine laboratory parameters are changed by ageing and are therefore only of limited value for diagnosis of anaemia. Soluble transferinreceptor and hepcidin are two parameters feasible for differential diagnosis of the causes of anaemia in the elderly.The most common cause of iron deficiency anaemia in the elderly is gastrointestinal bleeding. Many causes for gastrointestinal bleeding -like angiodysplasia of the colon - can readily be treated with endoscopic therapy. For this reason, colonoscopy is part of the standard workup for elderly patients with iron-deficient anaemia (IDA) if no contraindications exist.Therapy of anaemia is based on the specific cause or the causes. In IDA, the first step other than causal treatment is to replace iron orally. If this is not tolerated because of side effects or does not lead to a sufficient rise in the haemoglobin level, intravenous iron replacement therapy is indicated. Folic acid deficiency is generally treated orally, whereas vitamin B12 deficiency is generally treated by the parenteral - preferably subcutaneous - route. In anaemia due to chronic renal failure and anaemia due to myelodysplastic syndromes, the underlying cause must be treated, furthermore erythropoiesis-stimulating agents can be indicated.

    Conclusion:  Deterioration in olfactory threshold scores was found at 6 months after initiation of radiation therapy. Provided that these results are reproducible, an evaluation of olfactory functioning in patients with head and neck malignancies using in vivo dosimetry may be useful for determining the optimal dose for patients treated with conformal radiotherapy techniques while avoiding the side effects of radiation.

    Saliva as major human body fluid may act as an indicator of oral disease status. Oral mucositis is a common and often treatment-limiting side effect of radiotherapy for head and neck cancer patients. In this dataset, we provide the complete proteome dataset (raw and search files) of the patients at baseline of radiotherapy treatment in patients undergoing radiotherapy analyzed by nano liquid chromatography coupled to mass spectrometry (LC-MS/MS). In the data set, 5323 tryptic peptides were identified which can be assigned to 487 distinct proteins (≥2 peptides). The MS data have been deposited to the ProteomeXchange ("ProteomeXchange provides globally coordinated proteomics data submission and dissemination" [1]) via the PRIDE partner repository with the dataset identifier PRIDE: PXD003230. The data are associated with the previously published work, "Differences in the whole saliva baseline proteome profile associated with development of oral mucositis in head and neck cancer patients undergoing radiotherapy" [2].

  15. Prevention of nausea and vomiting in cancer patients undergoing chemo and radiotherapy: an investigational study

    International Nuclear Information System (INIS)

    Chemotherapy and radiotherapy-induced nausea and vomiting remains both a feared side effect of cancer treatment and a primary focus of many supportive care initiatives/guidelines. It is associated with severe morbidity and causes significant deterioration in quality of life of the cancer patients. The emetogenic potential of the chemotherapeutic agents, repeated chemotherapy cycles, the radiation dose, the site of tumor, and patient risk factors like female gender, younger age, alcohol consumption and history of motion sickness are the major risk factors. A combination of dexamethasone, serotonin receptor antagonists and H2 blockers has been used with success in the prevention of chemotherapy induced nausea and vomiting from both moderately and highly emetogenic chemotherapy. The present study addresses the experience of our hospital in the reduction of chemotherapy and radiotherapy induced nausea and vomiting among cancer patients. (author)

  16. Incidence of pneumonia and risk factors among patients with head and neck cancer undergoing radiotherapy

    International Nuclear Information System (INIS)

    This study investigated the incidence and patient- and treatment-related risk factors related to pneumonia acquired during radiotherapy (PNRT) in head and neck cancer (HNC) patients. Using the universal insurance claims data, 15,894 total HNC patients between 1998 and 2007 were included in this analysis. PNRT was defined as the occurrence of pneumonia within 90 days of the commencement of radiotherapy. Information also included some demographic characteristics, treatment-related factors, and comorbidities. Appropriate statistical tests were performed to assess the difference between patients with and those without PNRT. A logistic regression was used to estimate the odds ratio (OR) of PNRT among the variables examined. In total, 772 patients (4.86%) were identified with PNRT as the case group, whereas 15,122 subjects of the same cancer without PNRT formed the control group. Of patients with PNRT, 632 (81.9%) were hospitalized with a mean length of stay of 25.9 days. Results from the multiple logistic regression showed that an older age and certain comorbidities were associated with an increased risk of PNRT. Patients with cancer of the tongue, buccal mucosa, oropharynx, and hypopharynx/larynx were at particularly higher risk (OR = 1.28, 1.28, 1.67, and 1.74, respectively). Compared to radiotherapy alone, concurrent chemoradiotherapy had no effect on the PNRT. Patients in the PNRT group had higher overall medical costs and length of stay. The incidence of PNRT in HNC patients receiving radiotherapy was approximately 5%. Notably, an older age, certain comorbidities, and certain specific tumor sites were associated with an increased risk

  18. Predicted risks of radiogenic cardiac toxicity in two pediatric patients undergoing photon or proton radiotherapy

    International Nuclear Information System (INIS)

    Hodgkin disease (HD) and medulloblastoma (MB) are common malignancies found in children and young adults, and radiotherapy is part of the standard treatment. It was reported that these patients who received radiation therapy have an increased risk of cardiovascular late effects. We compared the predicted risk of developing radiogenic cardiac toxicity after photon versus proton radiotherapies for a pediatric patient with HD and a pediatric patient with MB. In the treatment plans, each patient’s heart was contoured in fine detail, including substructures of the pericardium and myocardium. Risk calculations took into account both therapeutic and stray radiation doses. We calculated the relative risk (RR) of cardiac toxicity using a linear risk model and the normal tissue complication probability (NTCP) values using relative seriality and Lyman models. Uncertainty analyses were also performed. The RR values of cardiac toxicity for the HD patient were 7.27 (proton) and 8.37 (photon), respectively; the RR values for the MB patient were 1.28 (proton) and 8.39 (photon), respectively. The predicted NTCP values for the HD patient were 2.17% (proton) and 2.67% (photon) for the myocardium, and were 2.11% (proton) and 1.92% (photon) for the whole heart. The predicted ratios of NTCP values (proton/photon) for the MB patient were much less than unity. Uncertainty analyses revealed that the predicted ratio of risk between proton and photon therapies was sensitive to uncertainties in the NTCP model parameters and the mean radiation weighting factor for neutrons, but was not sensitive to heart structure contours. The qualitative findings of the study were not sensitive to uncertainties in these factors. We conclude that proton and photon radiotherapies confer similar predicted risks of cardiac toxicity for the HD patient in this study, and that proton therapy reduced the predicted risk for the MB patient in this study

    The authors tested the effectiveness of orally administred delta-9-tetrahydrocannabinol (THC) as compared to prochlorperazine for the alleviation of symptoms, such as vomiting and nausea, experienced by patients receiving radiotherapy. The test subjects rated the severity of their illness, as well as the extent of their subsequent moods, their level of concentration, their amount of physical activity, and their desire for social interaction. They chose the drug they preferred and recorded its side effects. The use of THC was slightly more beneficial than the use of prochlorperazine.

  20. Prophylaxis of mucosal toxicity by oral propantheline and cryotherapy in children with malignancies undergoing myeloablative chemo-radiotherapy

    International Nuclear Information System (INIS)

    Mucosal toxicity is an incapacitating complication of intensive chemo-radiotherapy for children with malignant disorders, and is physically and psychologically distressful. It is therefore important to minimize mucosal toxicity in those patients. In this report, the effects of the combined prophylaxis of oral cooling (cryotherapy) and administration of propantheline, an anticholinergic drug, were studied in patients (aged 2-16 year) with acute leukemias or solid tumors, who underwent myeloablative chemo-radiotherapy and autologous peripheral blood stem cell rescue from 1993 to 1997. Patients were pretreated with the combined prophylaxis (n=12) or single prophylaxis (n=5), or left untreated (n=7). The combined prophylaxis significantly reduced the severe mucositis (combined, 8.3%; single, 20.0%; and untreated, 42.9%) and severe diarrhea (combined, 16.7%; single, 60.0%; and untreated, 57.1%). Moreover, the combined prophylaxis tended to shorten the periods of febrile episodes defined as temperature >38 deg C (combined, 3.8 days; single, 4.6 days; and untreated, 5.6 days). Therefore, the combination of propantheline and oral cryotherapy may be feasible and effective for reduction of mucosal toxicity in patients with malignancy who undergo high-dose chemotherapy.

Causal factors of distress are multifactorial; which encompasses physical, psychological, spiritual, and existential factors with complex interrelationship among the factors. Materials and Methods: Thirty patients undergoing head and neck radiotherapy were included in the study. Patients were screened for pain scores, distress scores, physical and psychological symptoms, and spiritual and emotional distress. Results: Significant increasing trend seen for pain score, distress score, and total number of symptoms during 2 nd week, 4 th week, and on completion of radiotherapy treatment (all P′s < 0.001 compared to pretreatment. Those who had chemotherapy (CT along with radiation had significantly greater pain score (t = 5.54, P = 0.03 and distress score (t = 3.9, P = 0.05 at 2 weeks into radiotherapy compared to those who did not receive CT. There was significantly higher grade of skin toxicity in those with spiritual distress (Somers′ d = 0.36, P = 0.02 and higher grade of mucositis in those with existential distress (d = 0.34, P = 0.02 at 4 weeks into radiotherapy. Conclusion: Positive correlation between distress score and pain score and occurrence of physical symptoms. Increasing trend seen for pain score, distress score, and total number of symptoms during 2 nd week, 4 th week, and completion of radiotherapy treatment compared to pretreatment. Increase in distress score in those with existential and spiritual distress.

  3. Does nutrition influence quality of life in cancer patients undergoing radiotherapy?

    International Nuclear Information System (INIS)

    Purpose: To investigate in cancer patients referred for radiotherapy (RT): (1) quality of life (QoL), nutritional status and nutrient intake, at the onset and at the end of RT; (2) whether individualised nutritional counselling, despite symptoms, was able to enhance nutrient intake over time and whether the latter influenced the patient's QoL; and (3) which symptoms may anticipate poorer QoL and/or reduced nutritional intake. Material and methods: One hundred and twenty-five patients with tumours of the head-neck/gastrointestinal tract (high-risk: HR), prostate, breast, lung, brain, gallbladder, uterus (low-risk: LR) were evaluated before and at the end of RT. Nutritional status was evaluated by Ottery's Subjective Global Assessment, nutritional intake by a 24-h recall food questionnaire and QoL by two instruments: EUROQOL and the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30. Results: Baseline malnutrition was prevalent in HR vs. LR (P=0.02); nutritional intake was associated with nutritional status (P=0.007); the latter did not change significantly during RT. In LR, baseline energy intake was higher than EER (P=0.001), and higher than HR' intake (P=0.002); the latter increased (P<0.03), in spite of symptom increase anew and/or in severity (P=0.0001). According to both instruments, QoL was always better in LR vs. HR (P=0.01); at the end of RT, QoL improvement in HR was correlated with increased nutritional intake (P=0.001), both remained stable in LR. Conclusions: Individualised nutritional counselling accounting for nutritional status and clinical condition, was able to improve nutritional intake and patients' QoL, despite self-reported symptoms

  4. Comparison of two indwelling central venous access catheters in dogs undergoing fractionated radiotherapy

    International Nuclear Information System (INIS)

    Twenty dogs with neoplasms requiring multiple radiation treatments received either percutaneous vascular access catheters (PVACs; Cook, Bloomington, IN) or subcutaneous vascular access ports (SVAPs; Vascular-Access-Ports, Norfolk Medical Products, Inc., Skokie, IL); 10 dogs were entered in each group. All catheters were implanted and removed aseptically and the catheter tips were cultured during implant removal. Complications with PVACs included mild incisional swelling and redness and accidental severance or rupture of the catheter. Complications with SVAPs included incisional or port swelling, bruising or redness, hematoma formation, and pain. Ports in 4 of these dogs could not be used for 1 to 3 days after surgery because of swelling and pain. Surgical wound complications, when pooled for comparison, occurred significantly more frequently with the SVAPs (P = .023). Wound complications associated with both catheters were self-limiting and resolved within 7 days. Bacterial cultures were positive in two PVACs and four SVAP tips, however, none of these dogs had clinical signs of infection or sepsis. Although both types of indwelling catheters were functional in a clinical setting, PVACs were preferred to SVAPs for dogs undergoing radiation therapy because of decreased time for implantation and fewer overall complications

    The incidence and nature of acute secondary irradiation esophagitis was studied in a series of 38 patients undergoing 60Co teletherapy for carcinoma of the lung. Thirty-four patients were male and four female, with ages ranging from 38 to 78 years. The mediastinum being irradiated in the process, all the patients underwent endoscopy for signs of esophagitis and/or gastritis after a dose of 30-40 Gy was delivered to the esophagus. Eighteen patients complained of dysphagia, but only in 12 of them did endoscopy show esophagitis. Of the remaining patients without complaints five had endoscopic signs of esophagitis. Gastritis was found in 18 cases and confirmed histologically in 14. In 17 cases, esophagitis and/or gastritis were confirmed histologically. It is believed that there is a fairly close correlation among clinical, endoscopic, and histological findings to support the claim that esophagitis in these patients is radiation induced. However, the cause of gastritis is not well understood. Data in the literature suggest that nonsteroid anti-inflammatory agents can act as prophylactic means of preventing radiation esophagitis.

    2011-09-01

    Full Text Available The aim of this study was to evaluate the occurrence of yeasts, pseudomonads and enteric bacteria in the oral cavity of patients undergoing radiotherapy (RT for treatment of head and neck cancer. Fifty patients receiving RT were examined before, during and 30 days after RT. Saliva, mucosa, and biofilm samples were collected and microorganisms were detected by culture and polymerase chain reaction (PCR. The most prevalent yeasts in patients submitted to RT were Candida albicans, C. tropicalis, C. krusei, C. glabrata and C. parapsilosis. Citrobacter, Enterobacter, Enterococcus, Klebsiella, Proteus, and Pseudomonas were the most frequently cultivated bacteria. Before RT, targeted bacteria were cultivated from 22.2% of edentulous patients and 16.6% of dentate patients; 30 days after RT, these microorganisms were recovered from 77.8% edentulous and 46.8% dentate patients. By PCR, these microorganisms were detected from all edentulous patients, 78.1% of dentate patients. The presence of Gram-negative enteric roads and fungi was particularly frequent in patients presenting mucositis level III or IV. Modifications in the oral environment due to RT treatment seem to facilitate the colonization of oral cavity by members of family Enterobacteriaceae, genera Enterococcus and Candida.

    Purpose: To implement and evaluate a magnetic resonance imaging atlas-based automated segmentation (MRI-ABAS) procedure for cortical and sub-cortical grey matter areas definition, suitable for dose-distribution analyses in brain tumor patients undergoing radiotherapy (RT). Patients and methods: 3T-MRI scans performed before RT in ten brain tumor patients were used. The MRI-ABAS procedure consists of grey matter classification and atlas-based regions of interest definition. The Simultaneous Truth and Performance Level Estimation (STAPLE) algorithm was applied to structures manually delineated by four experts to generate the standard reference. Performance was assessed comparing multiple geometrical metrics (including Dice Similarity Coefficient – DSC). Dosimetric parameters from dose–volume-histograms were also generated and compared. Results: Compared with manual delineation, MRI-ABAS showed excellent reproducibility [median DSCABAS = 1 (95% CI, 0.97–1.0) vs. DSCMANUAL = 0.90 (0.73–0.98)], acceptable accuracy [DSCABAS = 0.81 (0.68–0.94) vs. DSCMANUAL = 0.90 (0.76–0.98)], and an overall 90% reduction in delineation time. Dosimetric parameters obtained using MRI-ABAS were comparable with those obtained by manual contouring. Conclusions: The speed, reproducibility, and robustness of the process make MRI-ABAS a valuable tool for investigating radiation dose–volume effects in non-target brain structures providing additional standardized data without additional time-consuming procedures

  9. The impact of stool and gas volume on intrafraction prostate motion in patients undergoing radiotherapy with daily endorectal balloon

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to quantify the impact of rectal stool/gas volumes on intrafraction prostate motion for patients undergoing prostate radiotherapy with daily endorectal balloon (ERB). Methods: Total and anterior stool/gas rectal volumes were quantified in 30 patients treated with daily ERB. Real-time intrafraction prostate motion from 494 treatment sessions, at most 6 min in length, was evaluated using Calypso® tracking system. Results: The deviation of prostate intrafraction motion distribution was a function of stool/gas volume, especially when stool/gas is located in the anterior part of the rectum. Compared to patients with small anterior stool/gas volumes (<10 cm3), those with large volume (10–60 cm3) had a twofold increase in 3D prostate motion and interquartile data range within the 6th minute of treatment time. The 10% of the overall CBCT session where large anterior rectal volumes were observed demonstrated larger percentage of time at displacement greater than our proposed internal margin 3 mm. Conclusion: Volume and location of stool/gas can directly impact the ERB’s intrafraction immobilization ability. Although our patient preparation protocol and the 100 cm3 daily ERB effectively stabilized prostate motion for 90% of the fractions, a larger-sized ERB may improve prostate fixation for patients with greater and/or variable daily rectal volume

    Direct destruction and ineffective erythropoesis does not adequately explain the cause of anaemia in malaria. It is possible that there are more other mechanisms involved besides the causes described till date in malarial anaemia. The effect of NO on erythropoesis and a major haematological abnormality (microcytic/normocytic/megaloblastic picture) can significantly be observed on repeated exposure. In addition, NO can inhibit the enzyme methionine synthase so functional vit B12 deficiency state may occur which can lead to megaloblastic anaemia. This review will focus on causation of malarial anaemia and nitric oxide induced megaloblastic anaemia. PMID:19502689

  12. Is the Roach formula predictive for biochemical outcome in prostate cancer patients with minimal residual disease undergoing local radiotherapy after radical prostatectomy?

    International Nuclear Information System (INIS)

    Purpose: To find out if the risk of biochemical failure can be predicted applying the risk assessment for lymph-node metastases as suggested by the Roach formula for patients with minimal residual disease after radical prostatectomy undergoing adjuvant radiotherapy. Materials and methods: Patients after radical prostatectomy presenting with pT3-tumours or positive surgical margins, negative nodes and with a post-operative and pre-radiotherapy PSA level ≤0.1 ng/ml and without hormonal therapy were selected. Patients had received local 3D-conformal radiotherapy in the prostatic region with 66-72 Gy. According to the risk stratification of the Roach formula patients were divided into two groups: Group 1 with probability of positive lymph-nodes <15% and Group 2 with ≥15%. Biochemical recurrence was defined by reaching a PSA level ≥0.2 ng/ml. Results: A total of 55/288 patients could be identified, 26 patients in Group 1 and 29 patients in Group 2. Mean follow-up was 45 months. Biochemical recurrence free survival after 5 years was 78% for all patients and showed a significant difference between Group 1 (100%) and Group 2 with (58%; p = 0.004). Conclusion: The risk for biochemical failure after adjuvant radiotherapy in post-operative patients presenting with minimal residual disease is significantly influenced by the Roach formula. These findings are considered to provide a rationale for the decision on the volume of post-operative radiotherapy.

    Introduction. - Beginning 1998, a working group of specialists convened by the guidelines department (Standards, Options and Recommendations: S.O.R.) of the National French Federation of Comprehensive Cancer Centres (F.N.C.L.C.C.) published then regularly updated Recommendations relative to the use of ESA (epoetin alfa, epoetin beta, darbepoetin) in anemic patients with cancer. This article presents the updated Recommendations set up in 2007. Methods. - This updating process is based on the methodology developed and used in the 'Standards, Options: Recommendations' programme. The methodological approach combines systematic review with the judgement of a multidisciplinary group of experts. On the basis of analysis of literature, the conclusions and their level of evidence are established. Then, the conclusions accompanied by experts judgement lead to the Recommendations. A Recommendation is a proposal of one or several clinical attitudes intended to improve cancer patient care. Before publication, the R.P.C.-S.O.R. are re-examined by independent reviewers selected according to the same principles as the group of expert writers. Results. - New data, relative to the 'use of ESA in anemic cancer patients undergoing radiotherapy', did not lead to update the latest Recommendations validated in 2003. However, new data relative to the 'use of ESA in anaemia prophylaxis among adult patients with cancer' and to the 'use of iron with ESA in cancer patients' were sufficient to generate either major or minor modifications to the initial Recommendations. Conclusions. - Thus, it appears relevant to re-examine these Recommendations according to a systematic monitoring process which should be renewed in two years. (authors)

    This retrospective study tested the hypothesis that disease control and treatment-related toxicity in patients undergoing high-dose radiotherapy (HDRT) for prostate cancer varies in a circadian manner. Patients with localized prostate adenocarcinoma receiving HDRT (median 78 Gy) to the prostate and involved seminal vesicle(s) without elective pelvic irradiation were divided into a daytime treatment (before 5 PM) group (n = 267) and evening treatment (after 5 PM) group (n = 142). Biochemical failure (Phoenix definition), acute and late gastrointestinal (GI) and genitourinary toxicities (Common Terminology Criteria for Adverse Events version 4), biochemical failure-free survival (BFFS) and freedom from late toxicity were assessed. Analyses were performed by binary logistic regression and Cox proportional hazard regression. The median follow-up was 68 months, and 75% of patients were ≥70 years old. Evening HDRT was significantly associated with worse freedom from ≥grade 2 late GI complications (hazard ratio = 2.96; p < 0.001). The detrimental effect of evening HDRT was significant in patients older than 70 years old (p < 0.001) but not in younger patients (p = 0.63). In a subgroup of propensity score-matched cohort with T2b-T3 disease (n = 154), the 5-year BFFS was worse in the evening group than the daytime group (72% vs. 85%, hazard ratio = 1.95, p = 0.05). Our study indicates that evening HDRT may lead to more GI complications, especially in older patients, and worse BFFS in patients with T2b-T3 disease. PMID:26818960

  16. Gamma radiation induced genetic damage in the lymphocytes of the head and neck cancer patients undergoing radiotherapy

    International Nuclear Information System (INIS)

    Radiotherapy aims to kill or damage cancer cells. Often normal cells also get inevitably damaged permanently by this leading to secondary malignancies in these patients. Present study was aimed to know the genotoxic effects of ionizing radiation on lymphocytes of head and neck squamous cell carcinoma (HNSCC) patients exposed to various cumulative doses of gamma rays during radiotherapy. These patients were treated with cobalt 60 gamma radiation (External Beam Radiotherapy) for a period of five to six weeks with a daily fraction of 2 Gy for 5 days a week. Genotoxic effects of radiation in these patients were analysed employing chromosomal aberration test and alkaline comet assay (single cell gel electrophoresis/SCGE) techniques. Peripheral blood of these patients before starting with radiotherapy (pre-therapy) served as control and blood collected later on at weekly time intervals of the therapy during the course of radiotherapy served as treated (∼ 10, 20, 30, 40, 50 and 60 Gy) samples. Data were analysed employing student's t-test. Significant DNA damage was observed at the individual level in comparison with their pre-therapy baseline data in all patients. Inter-individual variation of the genotoxic effects were analysed using one way ANOVA. Present observations revealed the radiotherapy induced DNA damage in the non-target cells indicating the genotoxic effect of radiation at the doses studied. This may recommend the need to reduce the daily radiotherapy dose further to increase the safety of non-target cells. (author)

  18. Radiotherapy

    International Nuclear Information System (INIS)

    The need for radiotherapy research is exemplified by the 100,000 cancer patients who will fail treatment locally and/or regionally annually for the next several years but who would benefit from better local treatment modalities. Theoretically, all of the areas of investigation discussed in this projection paper have the potential to significantly improve local-regional treatment of cancer by radiotherapy alone or in combination with other modalities. In many of the areas of investigation discussed in this paper encouraging results have been obtained in cellular and animal tumor studies and in limited studies in humans as well. In the not too distant future the number of patients who would benefit from better local control may increase by tens of thousands if developments in chemotherapy and/or immunotherapy provide a means to eradicate disseminated microscopic foci of cancer. Thus the efforts to improve local-regional control take on even greater significance

  19. Absence of Symptom and Intact Liver Function Are Positive Prognosticators for Patients Undergoing Radiotherapy for Lymph Node Metastasis From Hepatocellular Carcinoma

    International Nuclear Information System (INIS)

    Purpose: The positive role of radiotherapy for patients with lymph node (LN) metastasis from hepatocellular carcinoma has recently been reported. The outcome and prognostic factors for these patients were analyzed. Methods and Materials: Between May 2004 and October 2007, 38 patients with LN metastases from hepatocellular carcinoma underwent radiotherapy. The median age was 59 years (range, 42-81). The radiation dose was 35-56 Gy with a fraction size of 1.8-3 Gy, for a biologically effective dose of 43.75-67.2 Gy10 (median, 59.0). The median follow-up period was 8 months. Results: The median survival time was 10 months. On univariate analysis, Child-Pugh class B (p = .0006), distant metastasis (p = .0095), symptoms related to metastatic LNs (p 10 (p = .0042) were significant prognostic factors predicting for poor overall survival. On multivariate analysis after adjustment using the Benjamini and Hochberg (false discovery rate) method, Child-Pugh class B (p = .04095) and the presence of symptoms (p = .04095) were associated with inferior overall survival. When patients were divided into three groups according to these two risk factors, the median survival for patients with no, either, or both risk factors was 20, 7, and 4 months, respectively (p <.0001). Conclusion: Patients with intact liver function and without related symptoms had the best prognosis when undergoing radiotherapy for LN metastasis from hepatocellular carcinoma.

    Measurement of arterial oxygen saturation by pulse oximetry was performed in two patients with acute and chronic anaemia (haemoglobin concentrations: 2.9 mmol/l (4.7 g/dl) and 1.9 mmol/l (3.0 g/dl), respectively) using a Radiometer OXI and a Nellcor N-200 pulse oximeter. The two oximeters read...... alternating different values in the two patients. In conclusion, pulse oximeters are able to give a value for oxygen saturation even at extreme anaemia, and when a high value is given, it possibly reflects arterial oxygen saturation. The value of pulse oximetry in severe anaemia is discussed....

  2. Randomized controlled trial to evaluate the effects of progressive resistance training compared to progressive muscle relaxation in breast cancer patients undergoing adjuvant radiotherapy: the BEST study

    International Nuclear Information System (INIS)

    Cancer-related fatigue (CRF) is one of the most common and distressing side effects of cancer and its treatment. During and after radiotherapy breast cancer patients often suffer from CRF which frequently impairs quality of life (QoL). Despite the high prevalence of CRF in breast cancer patients and the severe impact on the physical and emotional well-being, effective treatment methods are scarce. Physical activity for breast cancer patients has been reported to decrease fatigue, to improve emotional well-being and to increase physical strength. The pathophysiological and molecular mechanisms of CRF and the molecular-biologic changes induced by exercise, however, are poorly understood. In the BEST trial we aim to assess the effects of resistance training on fatigue, QoL and physical fitness as well as on molecular, immunological and inflammatory changes in breast cancer patients during adjuvant radiotherapy. The BEST study is a prospective randomized, controlled intervention trial investigating the effects of a 12-week supervised progressive resistance training compared to a 12-week supervised muscle relaxation training in 160 patients with breast cancer undergoing adjuvant radiotherapy. To determine the effect of exercise itself beyond potential psychosocial group effects, patients in the control group perform a group-based progressive muscle relaxation training. Main inclusion criterion is histologically confirmed breast cancer stage I-III after lumpectomy or mastectomy with indication for adjuvant radiotherapy. Main exclusion criteria are acute infectious diseases, severe neurological, musculosceletal or cardiorespiratory disorders. The primary endpoint is cancer-related fatigue; secondary endpoints include immunological and inflammatory parameters analyzed in peripheral blood, saliva and urine. In addition, QoL, depression, physical performance and cognitive capacity will be assessed. The BEST study is the first randomized controlled trial comparing progressive

    Purpose: One of the worst radiation-induced acute effects in treating head-and-neck (HN) cancer is grade 3 or higher acute (oral and pharyngeal) mucosal toxicity (AMT), caused by the killing/depletion of mucosa cells. Here we aim to testing a predictive model of the AMT in HN cancer patients receiving different radiotherapy schedules. Methods and Materials: Various radiotherapeutic schedules have been reviewed and classified as tolerable or intolerable based on AMT severity. A modified normal tissue complication probability (NTCP) model has been investigated to describe AMT data in radiotherapy regimens, both conventional and altered in dose and overall treatment time (OTT). We tested the hypothesis that such a model could also be applied to identify intolerable treatment and to predict AMT. This AMT NTCP model has been compared with other published predictive models to identify schedules that are either tolerable or intolerable. The area under the curve (AUC) was calculated for all models, assuming treatment tolerance as the gold standard. The correlation between AMT and the predicted toxicity rate was assessed by a Pearson correlation test. Results: The AMT NTCP model was able to distinguish between acceptable and intolerable schedules among the data available for the study (AUC = 0.84, 95% confidence interval = 0.75-0.92). In the equivalent dose at 2 Gy/fraction (EQD2) vs OTT space, the proposed model shows a trend similar to that of models proposed by other authors, but was superior in detecting some intolerable schedules. Moreover, it was able to predict the incidence of {>=}G3 AMT. Conclusion: The proposed model is able to predict {>=}G3 AMT after HN cancer radiotherapy, and could be useful for designing altered/hypofractionated schedules to reduce the incidence of AMT.

  5. Estimation of neutron-equivalent dose in organs of patients undergoing radiotherapy by the use of a novel online digital detector

    International Nuclear Information System (INIS)

    Neutron peripheral contamination in patients undergoing high-energy photon radiotherapy is considered as a risk factor for secondary cancer induction. Organ-specific neutron-equivalent dose estimation is therefore essential for a reasonable assessment of these associated risks. This work aimed to develop a method to estimate neutron-equivalent doses in multiple organs of radiotherapy patients. The method involved the convolution, at 16 reference points in an anthropomorphic phantom, of the normalized Monte Carlo neutron fluence energy spectra with the kerma and energy-dependent radiation weighting factor. This was then scaled with the total neutron fluence measured with passive detectors, at the same reference points, in order to obtain the equivalent doses in organs. The latter were correlated with the readings of a neutron digital detector located inside the treatment room during phantom irradiation. This digital detector, designed and developed by our group, integrates the thermal neutron fluence. The correlation model, applied to the digital detector readings during patient irradiation, enables the online estimation of neutron-equivalent doses in organs. The model takes into account the specific irradiation site, the field parameters (energy, field size, angle incidence, etc) and the installation (linac and bunker geometry). This method, which is suitable for routine clinical use, will help to systematically generate the dosimetric data essential for the improvement of current risk-estimation models. (paper)

    Full Text Available Objectives: The present study was carried to find out the frequency of haemolytic anaemia, to know the different etiological factors and their percentage in the region of marathwada, Maharashtra. Background: Knowledge of frequency and different etiological factors is essential for the information of magnitude and treatment of the patients. The present study was done in the department of pathology, Gov. Medical College, Aurangabad, district of Maharashtra. The patients from marathwada region of the Maharashtra were included in this study. The concerned study of “Haemoglobinopathies in Childhood” was conducted by Anil J in 1984 in the same institute. Methodology: Total 76 clinically suspected cases were investigated. For the study routine investigations like Hb estimation, peripheral blood smear examination, reticulocyte count and special investigations like sickling test, Hb solubility test, estimation of faetal haemoglobin and Hb electrophoresis were carried out. Results: Total 76 cases were studied. Out of it 51 cases were male (67.10% and 25 (32.89% cases were female. The patients are in the age group, 5 months to 45 years. Out of 76 cases 51 cases were diagnosed as haemolytic anaemia. In these 51 cases of haemolytic anaemia, 42 cases (82.35% of haemoglobinopathies, it cases (15.68% of malaria and one case (1.96% of auto immune haemolytic anaemia were found to have as causative factor. Conclusion: It showed that the frequency of haemolytic anaemia in studied 76 cases was 67.10%. In diagnosed 51 cases of haemolytic anaemia, the causative factor as haemoglobinopathy was 82.35% and other than haemoglobinopathy was 17.65%. It also showed that majority of the cases in this region were belonging to beta thalassaemia major, which is more common in western zone of India followed by sickle cell anaemia.

  7. Anaemia and radiation therapy

    International Nuclear Information System (INIS)

    Anaemia is frequent in cancer and may increase tumour hypoxia that stimulates angiogenesis. However, erythropoietin is a hypoxia-inducible stimulator of erythropoiesis which seems to improve quality of life in cancer patients. Two recent phase III randomized studies showed negative results using erythropoietin in head and neck cancer patients and in metastatic breast cancer patients with impaired specific survival. In vitro and in vivo experiments have provided erythropoietin-receptor expression in endothelial cancer cells including malignant tumours of the breast, prostate, cervix, lung, head and neck, ovary, melanoma, stomach, gut, kidney etc. Biologic effect of erythropoietin and its receptor linkage induces proliferation of human breast cancer and angiogenesis and may limit anti-tumour effect of cancer treatment, in part, by tumour vascularization improvement. In addition, the use of exogenous erythropoietin could be able to favour tumour progression by improving tumour oxygenation and nutriment supply. If erythropoietin receptor were functional in human cancer. the assessment of erythropoietin receptor expression on tumour cell may help to select patients benefiting from exogenous erythropoietin. However. the relationship between erythropoietin receptor expression, tumour growth and exogenous erythropoietin. requires more studies. The results of recent clinical trials suggest that using erythropoietin should be avoided in non-anemic patients and discussed in patients receiving curative therapy. (authors)

  8. Determination of cytokine protein levels in oral secretions in patients undergoing radiotherapy for head and neck malignancies

    International Nuclear Information System (INIS)

    Cytokines may be elevated in tumor and normal tissues following irradiation. Cytokine expression in these tissues may predict for toxicity or tumor control. The purpose of this pilot study was to determine the feasibility of measuring local salivary cytokine levels using buccal sponges in patients receiving chemo-radiation for head and neck malignancies. 11 patients with epithelial malignancies of the head and neck were recruiting to this study. All patients received radiotherapy to the head and neck region with doses ranging between 60 – 67.5 Gy. Chemotherapy was delivered concurrently with radiation in all patients. Salivary samples were obtained from high dose and low dose regions prior to treatment and at three intervals during treatment for assessment of cytokine levels (IL-4, IL-6, IL-8, IL-10, EGF, MCP-1, TNF-α, and VEGF). Cytokine levels were detectable in the salivary samples. Salivary cytokine levels of IL-4, IL-6, IL-8, EGF, MCP-1, TNF- α , and VEGF were higher in the high dose region compared to the low dose region at all time points (p < 0.05). A trend toward an increase in cytokine levels as radiation dose increased was observed for IL-6, IL-8, MCP-1, and TNF-α. Assessment of salivary cytokine levels may provide a novel method to follow local cytokine levels during radiotherapy and may provide a mechanism to study cytokine levels in a regional manner

    International Nuclear Information System (INIS)

    Objective: To evaluate the effects of panaxatriol in quinquefolium leaf (PQL) on immune functions in the patients with breast carcinoma undergoing radiotherapy. Methods: Thirty patients with breast carcinoma undergoing radiotherapy were randomly divided into 2 groups: panaxatriol treatment group (n=17) and control group (n=13). All patients in panaxatriol treatment group were administrated with PQL as well as radiotherapy, no administration in control group. After radiotherapy with 40 Gy, the white cells count and IgG, IgA, IgM, C3, and C4 values, and the percentages of CD4+, CD8+, CD25+ and lymphocyte transformation rate of peripheral blood in the patients were examined. Results: There were (4.02 ± 0.67) x 109 ·L-1 and (6.17 ± 1.20) x 109 ·L-1 white blood cells, respectively, in control and PQL groups. The lymphocyte transformation rate of peripheral blood were 7966 ± 1562 in the control group, while 18035 ± 1577 in PQL group, which was significantly higher than that in control group (P+ and CD25+ T lymphocytes in PQL group were significantly higher than those in control group (P<0.05, P<0.001). Conclusion: The PQL could enhance the cellular immune function in patients with breast carcinoma undergoing radiotherapy. (authors)

  12. A prospective randomized comparative clinical trial comparing the efficacy between ondansetron and metoclopramide for prevention of nausea and vomiting in patients undergoing fractionated radiotherapy to the abdominal region

    International Nuclear Information System (INIS)

    This study is a prospective randomized clinical trial comparing the efficacy and complication of anti-emetic drugs for prevention of nausea and vomiting after radiotherapy which has moderate emetogenic potential. The aim of this study was to investigate whether the anti-emetic efficacy at ondansetron(Zofran) 8 mg bid dose (Group O) is better than the efficacy of metoclopramide 5 mg tid dose (Group M) in patients undergoing fractionated radiotherapy to the abdominal region. Study entry was restricted to those patients who met the following eligibility criteria: histologically confirmed malignant disease; no distant metastasis; performance status of not more than ECOG grade 2; no previous chemotherapy and radiotherapy. Between March 1997 and February 1998, 60 patients enrolled in this study. All patients signed a written statement of informed consent prior to enrollment. Blinding was maintained by dosing identical number of tables including one dose of matching placebo for Group O. The extent of nausea, appetite loss, and the number of emetic episodes were recorded everyday using diary card.

    This study is a prospective randomized clinical trial comparing the efficacy and complication of anti-emetic drugs for prevention of nausea and vomiting after radiotherapy which has moderate emetogenic potential. The aim of this study was to investigate whether the anti-emetic efficacy at ondansetron(Zofran) 8 mg bid dose (Group O) is better than the efficacy of metoclopramide 5 mg tid dose (Group M) in patients undergoing fractionated radiotherapy to the abdominal region. Study entry was restricted to those patients who met the following eligibility criteria: histologically confirmed malignant disease; no distant metastasis; performance status of not more than ECOG grade 2; no previous chemotherapy and radiotherapy. Between March 1997 and February 1998, 60 patients enrolled in this study. All patients signed a written statement of informed consent prior to enrollment. Blinding was maintained by dosing identical number of tables including one dose of matching placebo for Group O. The extent of nausea, appetite loss, and the number of emetic episodes were recorded everyday using diary card. The mean score of nausea, appetite loss and the mean number of emetic episodes were obtained in a weekly interval. Prescription error occurred in one patient. And diary cards have not returned in 3 patients due to premature refusal of treatment. Card from one patient was excluded from the analysis because she had a history of treatment for neurosis. As a result, the analysis consisted of 55 patients. Patient characteristics and radiotherapy characteristics were similar except mean age was 52.9{+-} 11.2 in group M, 46.5{+-}9.6 in group O.

    Full Text Available Direct destruction and ineffective erythropoesis does not adequately explain the cause of anaemia in malaria. It is possible that there are more other mechanisms involved besides the causes described till date in malarial anaemia. The effect of NO on erythropoesis and a major haematological abnormality (microcytic/normocytic/megaloblastic picture can significantly be observed on repeated exposure. In addition, NO can inhibit the enzyme methionine synthase so functional vit B12 deficiency state may occur which can lead to megaloblastic anaemia. This review will focus on causation of malarial anaemia and nitric oxide induced megaloblastic anaemia.

  15. Prospective Evaluation to Establish a Dose Response for Clinical Oral Mucositis in Patients Undergoing Head-and-Neck Conformal Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: We conducted a clinical study to correlate oral cavity dose with clinical mucositis, perform in vivo dosimetry, and determine the feasibility of obtaining buccal mucosal cell samples in patients undergoing head-and-neck radiation therapy. The main objective is to establish a quantitative dose response for clinical oral mucositis. Methods and Materials: Twelve patients undergoing radiation therapy for head-and-neck cancer were prospectively studied. Four points were chosen in separate quadrants of the oral cavity. Calculated dose distributions were generated by using AcQPlan and Eclipse treatment planning systems. MOSFET dosimeters were used to measure dose at each sampled point. Each patient underwent buccal sampling for future RNA analysis before and after the first radiation treatment at the four selected points. Clinical and functional mucositis were assessed weekly according to National Cancer Institute Common Toxicity Criteria, Version 3. Results: Maximum and average doses for sampled sites ranged from 7.4-62.3 and 3.0-54.3 Gy, respectively. A cumulative point dose of 39.1 Gy resulted in mucositis for 3 weeks or longer. Mild severity (Grade ≤ 1) and short duration (≤1 week) of mucositis were found at cumulative point doses less than 32 Gy. Polymerase chain reaction consistently was able to detect basal levels of two known radiation responsive genes. Conclusions: In our sample, cumulative doses to the oral cavity of less than 32 Gy were associated with minimal acute mucositis. A dose greater than 39 Gy was associated with longer duration of mucositis. Our technique for sampling buccal mucosa yielded sufficient cells for RNA analysis using polymerase chain reaction

  16. Genetic variant in CD44 confer susceptibility to acute skin reaction in breast cancer patients undergoing radiotherapy

    International Nuclear Information System (INIS)

    Heterogeneity in toxicity to normal tissue is observed in 10% of cancer patients after radiotherapy (RT) which limits the therapeutic outcome. Response to RT is manifested from alterations in gene of vivid pathways involving DNA damage-repair, inflammatory cytokine, cell cycle regulation, antioxidant response etc. Therefore, the common sequence variants in these radioresponsive genes may modify the severity of normal tissue toxicity and identification of the same may have clinical relevance as a predictive biomarker. The present study was aimed to evaluate the potential modifying role of genetic variants in NFE2L2, OGG1, NEIL3, RAD17, PTTG1, REV3L, ALAD, CD44, RAD9A, LIG3, SH3GL1, BAXS, XRCC1, MAD2L2 and TGFBR3 on the individual susceptibility to RT induced acute skin reactions. All the 132 breast cancer patients were treated with a total dose of 50 Gy in case of mastectomy and 60 Gy in breast conservation surgery. The severity of skin damage was scored according to the Radiation Therapy Oncology Group (RTOG) criteria and the toxicity scores were dichotomized as non-over-responders (NOR; RTOG<2) and over-responders (NOR;RTOG>2) for analysis. Out of the 132 subjects, 44 were ORs. Among the 20 studied SNPs of indicated genes, the rs8193 (CD44) polymorphism lying in the miRNA binding site was significantly (p<0.05) associated with the RT induced adverse skin reactions. The non-coding CD44 3'-UTR serves as a competitor for miRNA binding and subsequently inactivates miRNA functions, by freeing the target mRNAs from being repressed. Therefore, though the role of CD44 in radiosensitivity is unknown, the change in the miRNA binding to CD44mRNA transcripts may regulate expression of several genes involved in pathophysiology of normal tissue radiosensitivity leading to the observed outcome.

  17. A Phase III placebo-controlled trial of oral pilocarpine in patients undergoing radiotherapy for head-and-neck cancer

    International Nuclear Information System (INIS)

    Purpose: To test the hypothesis that the use of oral pilocarpine during and after radiotherapy (RT) for head-and-neck cancer would reduce the symptoms of post-RT xerostomia. Methods and Materials: One hundred thirty patients were randomized in a double-blind method to receive either pilocarpine (5-mg tablets) or placebo three times daily starting on Day 1 of RT and continuing for 1 month after treatment. The eligibility criteria included a planned dose of >50 Gy as radical or postoperative RT for head-and-neck cancer, with at least 50% of both parotid glands included in the treatment fields. The primary outcome measure was the severity of xerostomia as assessed by a patient-completed linear analog scale 3 months after RT. Secondary outcome measures included quality of life during therapy (as assessed by the McMaster University Head-and-Neck Questionnaire) and severity of mucositis during RT (as assessed using Radiation Therapy Oncology Group scales). Results: No difference was observed between the pilocarpine-treated patients and the placebo group in the severity of xerostomia score as assessed by linear analog scale at baseline and 1, 3, and 6 months after treatment (repeated measures analysis, p=0.92). No difference was apparent in the severity of mucositis during RT; 56.3% of patients receiving pilocarpine had Grade III/IV mucositis compared with 50.8% treated with placebo. No difference in quality of life was noted between the treatment groups during or after RT. The questionnaire score at 3 months after RT was 5.0 (SD 1.0). in the pilocarpine group and 4.9 (SD 0.9) in the placebo group. Conclusion: We were unable to detect a beneficial effect of pilocarpine on RT-induced xerostomia when administered during RT for head-and-neck cancer

  18. Phase II study assessing the effectiveness of Biafine cream as a prophylactic agent for radiation-induced acute skin toxicity to the breast in women undergoing radiotherapy with concomitant CMF chemotherapy

    International Nuclear Information System (INIS)

    Purpose: To assess the efficacy of Biafine cream in preventing Grade 2 acute radiation dermatitis, according to the National Cancer Institute of Canada skin radiation toxicity criteria in patients undergoing concomitant adjuvant chemotherapy and radiotherapy to the breast. Methods and Materials: Sixty patients participated in this study. Patients were treated with a lumpectomy followed by concomitant chemotherapy and radiotherapy to the breast. Biafine cream was applied daily, starting on the first day and ending 2 weeks post-radiotherapy. Patients underwent weekly skin assessments throughout radiotherapy and at 2 and 4 weeks after treatment. Outcome measures were assessed using a Skin Assessment Questionnaire that was scored according to the National Cancer Institute of Canada skin radiation toxicity criteria and a self-administered questionnaire that evaluated skin symptoms. Results: The maximum skin toxicity observed during the course of treatment was as follows: less than Grade 2 toxicity, 15% (9 patients); Grade 2, 83% (50 patients); Grade 3, 2% (1 patient); Grade 4, 0% (0 patients). The majority of the radiation dermatitis was observed after 3 weeks of radiotherapy. Conclusion: The majority of patients who underwent concomitant chemo- and radiotherapy for breast cancer developed Grade 2 radiation dermatitis with the use of Biafine cream. However, no treatment delays or interruptions were observed because of skin toxicity

  19. Estimation of the risk of secondary cancer in the thyroid gland and the breast outside the treated volume in patients undergoing brain, mediastinum and breast radiotherapy

    International Nuclear Information System (INIS)

    The purpose of this study was to measure the peripheral dose which is the absorbed dose in organs located outside the treatment volume such as the thyroid gland and the breast in patients undergoing radiotherapy, utilising the MOSFET dosemeters, as well as to estimate the probability of secondary cancer. The thyroid gland doses, expressed as a percentage of the prescribed dose (%TD), were measured to be 2.0±0.3 %, in whole brain irradiation, 10.0±8.0 % in mediastinum treatment and 8.0±2.0 and 2.0±0.8 % in breast treatment, with and without the supraclavicular irradiation, respectively, with a corresponding risk of 0.2, 2.0, 1.0 and 0.3 %. The dose to the breast was 7.0±2.0 %, in the mediastinum treatment, and 4.0±1.0 and 2.0±0.8 %, in the breast treatment, with and without supraclavicular irradiation, respectively, with a corresponding risk of 4.0, 2.0 and 1.0 %. Although the results indicate that the risk is not negligible, its significance should be considered in conjunction with the existing pathology and age of the patients. (authors)

    1993-01-01

    In a multicentre, international double-blind trial, patients undergoing courses of five or more daily radiotherapy treatments to the upper abdomen were randomized to receive either oral ondansetron 8 mg t.d.s. or oral prochlorperazine 10 mg t.d.s. throughout their radiation course in order to try to prevent nausea and vomiting. A total of 192 patients were recruited, 135 of whom were included in the efficacy analysis; of these, 70 received ondansetron and 65 prochlorperazine. Forty-three (61%) of the patients prescribed ondansetron and 23 (35%) of those given prochlorperazine had a complete response, with no emetic episodes throughout their treatment course. There was, however, no significant difference between the two groups with respect to the incidence and severity of nausea. Seventeen (24%) of the patients on ondansetron and 19 (29%) of those given prochlorperazine were treatment failures, experiencing more than five emetic episodes on their worst day during the study. Both drugs were well tolerated, although constipation was seen more commonly with ondansetron. (author).

    Full Text Available Anaemia in pregnancy defined as haemoglobin (Hb level of < 10 gm/dL, is a qualitative or quantitative deficiency of Hb or red blood cells in circulation resulting in reduced oxygen (O 2 -carrying capacity of the blood. Compensatory mechanisms in the form of increase in cardiac output (CO, PaO 2 , 2,3 diphosphoglycerate levels, rightward shift in the oxygen dissociation curve (ODC, decrease in blood viscosity and release of renal erythropoietin, get activated to variable degrees to maintain tissue oxygenation and offset the decreases in arterial O 2 content. Parturients with concomitant medical diseases or those with acute ongoing blood losses may get decompensated, leading to serious consequences like right heart failure, angina or tissue hypoxemia in severe anaemia. Preoperative evaluation is aimed at assessing the severity and cause of anaemia. The concept of an acceptable Hb level varies with the underlying medical condition, extent of physiological compensation, the threat of bleeding and ongoing blood losses. The main anaesthetic considerations are to minimize factors interfering with O 2 delivery, prevent any increase in oxygen consumption and to optimize the partial pressure of O 2 in the arterial blood. Both general anaesthesia and regional anaesthesia can be employed judiciously. Monitoring should focus mainly on the adequacy of perfusion and oxygenation of vital organs. Hypoxia, hyperventilation, hypothermia, acidosis and other conditions that shift the ODC to left should be avoided. Any decrease in CO should be averted and aggressively treated.

    Full Text Available Vitamin B12 deficiency is uncommon in pregnancy, it occurs in 10–28% of uncomplicated pregnancies, and is associated with a few complications. We present a case report of a 21-year-old patient with severe anaemia during late pregnancy caused by vitamin B12 deficiency. At 38 weeks gestation and with a BMI of 48.9, a history of rupture of membranes was given but not confirmed. On examination, she appeared pale and therefore full blood counts were done. Interestingly her haemoglobin (Hb levels were 3.7 g/dL. Folate and vitamin B12 levels were also found to be low, and the diagnosis of anaemia caused by vitamin B12 deficiency was made. After treatment with vitamin B12 injections, folic acid and blood transfusions, the patient’s haemoglobin levels improved from 3.7 g/dL to 10.7 g/dL. The conclusion is that effective history taking, diagnosis, and management can prevent many complications that are usually associated with vitamin B12 deficiency anaemia.

    2015-04-01

    This report demonstrates pulmonary haemorrhage as a differential cause of anaemia. Idiopathic pulmonary hemosiderosis is a rare disease in children; it is classically described as a triad of haemoptysis, pulmonary infiltrates on chest radiograph, and iron-deficiency anaemia. However, anaemia may be the only presenting feature of idiopathic pulmonary hemosiderosis in children due to occult pulmonary haemorrhage. In addition, the serum ferritin is falsely high in idiopathic pulmonary hemosiderosis which increases the diagnostic difficulty. We recommend that pulmonary haemorrhage be suspected in any child presenting with iron-deficiency anaemia and persistent bilateral pulmonary infiltrates. PMID:25904566

The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. Objectives. - To update the Standards, Options and Recommendations clinical practice guidelines for the use of recombinant erythropoietin (epoietin alpha and beta darbepoietin-alpha, EPO) in the management of anaemia in oncology for patient undergoing radiotherapy. Methods. - The working group identified the questions requiring up-dating from the previous guideline. Medline and Embase were searched using specific search strategies from January 1999 to October 2002. Literature monitoring was performed to identify randomized clinical trials published between October 2002 to November 2003. In addition several Internet sites were searched in October 2002. Results. - There is no standard attitude for use of rHuEPO in patients undergoing radiotherapy. There is no evidence to support use of rHuEPO in patients with ENT cancer receiving radiotherapy alone. In patients undergoing curative radiotherapy, it is recommended to correct anaemia under 10 g/dL using transfusion rather than rHuEPO. When the haemoglobin concentration is between 12 g/dL and 14 g/dL initial use of rHuEPO can be an option under certain conditions for radio-chemotherapy if the risk of anaemia is

    The acute side effects of radiation therapy are of different quality while respect to the irradiated area. The frequency and severity of these side effects are determined by the primary goal of either a palliative or curative therapy. The through analysis of the extent of the tumour and the narrowing of the irradiated volume will allow a reduction of side effects without compromising the safety of local control. (orig.)

    Full Text Available New challenges and priorities are given in the EU Health programme 2007-2013. The objectives of the programme are to improve citizens’ health security, to promote health to improve prosperity and solidarity, and to generate and disseminate health knowledge. If challenges and priorities have been defined globally for rare diseases by the European Commission, persons involved in rare anaemias have taken the opportunity to contribute to the empowerment of patients with rare anaemias. One of the ENERCA partners objectives was the mapping of existing centres that take care of patients with rare anaemias in Europe. Another goal was to obtain a directory of facilities available per centre for patients with rare anaemias. We thought that with those results it could realistically help to define a consensus regarding the criteria to be recognised as a centre of expertise for haemoglobinopathies and very rare anaemias.

  10. The UK HeartSpare Study: Randomised evaluation of voluntary deep-inspiratory breath-hold in women undergoing breast radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To determine whether voluntary deep-inspiratory breath-hold (vDIBH) and deep-inspiratory breath-hold with the active breathing coordinator™ (ABCDIBH) in patients undergoing left breast radiotherapy are comparable in terms of normal-tissue sparing, positional reproducibility and feasibility of delivery. Methods: Following surgery for early breast cancer, patients underwent planning-CT scans in vDIBH and ABCDIBH. Patients were randomised to receive one technique for fractions 1–7 and the second technique for fractions 8–15 (40 Gy/15 fractions total). Daily electronic portal imaging (EPI) was performed and matched to digitally-reconstructed radiographs. Cone-beam CT (CBCT) images were acquired for 6/15 fractions and matched to planning-CT data. Population systematic (Σ) and random errors (σ) were estimated. Heart, left-anterior-descending coronary artery, and lung doses were calculated. Patient comfort, radiographer satisfaction and scanning/treatment times were recorded. Within-patient comparisons between the two techniques used the paired t-test or Wilcoxon signed-rank test. Results: Twenty-three patients were recruited. All completed treatment with both techniques. EPI-derived Σ were ⩽1.8 mm (vDIBH) and ⩽2.0 mm (ABCDIBH) and σ ⩽2.5 mm (vDIBH) and ⩽2.2 mm (ABCDIBH) (all p non-significant). CBCT-derived Σ were ⩽3.9 mm (vDIBH) and ⩽4.9 mm (ABCDIBH) and σ ⩽ 4.1 mm (vDIBH) and ⩽ 3.8 mm (ABCDIBH). There was no significant difference between techniques in terms of normal-tissue doses (all p non-significant). Patients and radiographers preferred vDIBH (p = 0.007, p = 0.03, respectively). Scanning/treatment setup times were shorter for vDIBH (p = 0.02, p = 0.04, respectively). Conclusions: vDIBH and ABCDIBH are comparable in terms of positional reproducibility and normal tissue sparing. vDIBH is preferred by patients and radiographers, takes less time to deliver, and is cheaper than ABCDIBH

    For fifty years, the radio therapists have been working on the concept of oxygen effect, that corresponds to the reduction of the biological effect observed with the low linear energy transfer radiation (Let) used in routine when irradiated cells are exposed to a low concentration in oxygen. The appearance of erythropoietin at the beginning of 1990 has reopened the debate: clean molecules without any risk in transfusion, allowing to increase the hemoglobin concentration for the cancerous patients. The benefit of anemia correction could be important and the article of Henke and al. constitutes a first step in the research of new therapies. (N.C.)

    International Nuclear Information System (INIS)

    Full text:Background: Tumour hypoxia is associated with disease progression and resistance to therapy. High grade cerebral gliomas have a poor outcome despite advancements in chemotherapy and radiotherapy. 18F-fluoromisonidazole (18F-FMISO) concentrates in hypoxic cells and is associated with tumour grade in gliomas. The aim of this study was to compare the patterns of uptake of 18F-FDG PET and 18F-FMISO PET post-surgery with MRI and areas of recurrence post-radiotherapy. Methods: Patients with high grade cerebral glioma were recruited into this prospective study. All patients had post-surgical, pre-radiotherapy 18F-FDG, 18F-FMISO and MRI scans, which were all repeated 4-6 weeks post-completion to radiotherapy. The patients were followed-up clinically three monthly and re-imaged if indicated. Results: Ten patients were enrolled in this study, mean age 62 years (range 55-69 years), who all had pre-radiotherapy scans performed. Seven patients had scans done pre- and post-radiotherapy, with 3 patients with only pre-therapy scans. Nine patients had significant FMISO uptake and 8 patients demonstrated abnormal FDG uptake. The areas of FMISO uptake on pre-radiotherapy scans correlated with the most abnormal areas of contrast-enhancement on pre-treatment MRI and areas of locally recurrent disease on post-treatment MRI in eight patients. Nine patients had locally recurrent disease on follow-up MRI. FMISO was more predictive of tumour recurrence compared to FDG. Conclusion: Post-surgical 18F-FMISO PET in patients with cerebral glioma is more predictive of areas of recurrent disease compared to 18F-FDG PET.

    Direct destruction and ineffective erythropoesis does not adequately explain the cause of anaemia in malaria. It is possible that there are more other mechanisms involved besides the causes described till date in malarial anaemia. The effect of NO on erythropoesis and a major haematological abnormality (microcytic/normocytic/megaloblastic picture) can significantly be observed on repeated exposure. In addition, NO can inhibit the enzyme methionine synthase so functional vit B12 deficiency sta...

    Background Anaemia and iron deficiency are common complications following post-bariatric abdominoplasty. Given the low oral absorbability of iron resulting from bariatric surgery, it has been hypothesised that postoperative intravenously administered iron supplementation could be used to treat anaemia and to prevent the development of iron deficiency in these patients. Methods/Design In this multicentre open-label randomised clinical trial, 56 adult women undergoing post-bariatric anchor-line...

    Full Text Available Background and Objectives: Oral mucositis is a common and debilitating complication of radiotherapy, which is associated with significant morbidity. It is therefore extremely important that mucositis be prevented, or at least treated to reduce its severity and sequelae. The objective of the study was to manage oral mucositis induced by radiotherapy and to reduce pain by using Benzydamine hydrochloride (0.15%, Chlorhexidine (0.2%, and Povidone iodine (5%. Results: Benzydamine hydrochloride was observed to be effective and delayed the development of severe form of mucositis and appears more efficient in the management of radiation-induced mucositis. Conclusion: Benzydamine hydrochloride (0.15% is safe, well tolerated, helps not just in delaying the progression of mucositis but also reduces the intensity of pain.

    Objectives: This study evaluated for the first time in intraindividual comparison the conception of care with creme or powder. Acute skin reactions on the left and right side of the neck during symmetrically performed radiotherapy and subjective impairment were assessed. Patients and Methods: Twelve patients receiving radiotherapy of the head-and-neck region up to 50, 60, 66 and 72 Gy, respectively, were asked to treat one side of the neck with creme, the contralateral side with powder after random assignment. Objective and subjective assessment and photodocumentation were performed at therapy onset and weekly during therapy. The photodocumentation provides an impressive course of acute skin reactions under these care concepts. Results: Altogether we saw no relevant difference in favor of care with creme or powder according to objective as well as subjective assessment criteria (Figures 2 and 3). In this intraindividual comparison the results are independent from interindividual different sensitivity to radiotherapy, total dose or fractionation. Therefore the small patient number is a minor limitation for evidence. Our results are in accordance to trials comparing other care concepts. Conclusions: A relevant effect concerning onset and degree of acute skin reactions or differences in symptom relief could not be demonstrated. Both conceptions are to be regarded equal in terms of subjective symptom relief and in extent of acute skin reactions. The lack of differences may be explained by the fact that the underlying pathophysiological processes cannot be influenced by topical agents. (orig.)

    Full Text Available O câncer de mama é a forma de câncer que mais causa mortes entre mulheres no Brasil. O tratamento consiste em intervenção cirúrgica, quimioterapia, hormonioterapia e radioterapia, esta última responsável por uma significativa diminuição na taxa de recorrência local do câncer, mas que pode afetar a função pulmonar. O objetivo deste estudo foi detectar alterações pulmonares funcionais decorrentes da radioterapia no tratamento do câncer de mama. Participaram do estudo 10 mulheres submetidas a tratamento do câncer de mama, avaliadas quanto à função pulmonar antes e após a radioterapia. Foram mensuradas capacidade inspiratória e capacidade vital forçada, por espirômetro de incentivo, e pressões inspiratória e expiratória máximas, por manovacuômetro. Embora tenha havido redução, em vários casos, dos valores medidos antes e depois da radioterapia, não foi encontrada diferença estatisticamente significativa. Nas pacientes avaliadas, pois, a radioterapia não parece ter prejudicado a função pulmonar.Breast cancer is the cancer that most causes death among women in Brazil. The treatment consists in surgery, chemotherapy, hormontherapy, and radiotherapy, the latter being responsible for important decrease in recurrence rates, though it may affect pulmonary function. The aim of this study was to detect lung function changes due to radiotherapy in breast cancer treatment. Ten women who were undergoing breast cancer treatment were assessed as to pulmonary function before and after radiotherapy. Measurements taken were inspiratory capacity and forced vital capacity, by means of incentive spirometer, and maximum inspiratory and expiratory pressures, using a pressure meter. Though in many cases measures found after radiotherapy were lower, no significant difference could be found. Thus radiotherapy did not seem to affect lung function in the assessed sample of women with breast cancer.

    The present study examined the relationship between anaemia and tumour response to radiation given in air or HPO in C{sub 3}H mice transplanted with a mammary adenocarcinoma using a growth delay assay to assess radiation response. Radiation studies with these anaemic mice demonstrated that the tumour radiosensitivity was decreased when treatment was given in air. HPO was successful in overcoming the increased radioresistance associated with anaemia. This result suggested that tumours grown in anaemic mice have a higher hypoxic fraction than those grown in control mice. Changes in host physiology with chronic anaemia may contribute to the benefit seen with HPO but such alterations per se may be inadequate to maintain tumour oxygenation when treatment is given in air.

    Full Text Available BACKGROUND: Anaemia is the commonest global public health problem and especially harmful when the pregnancy is complicated by anaemia. Women in reproductive age group are more vulnerable for iron deficiency anaemia with an estimated prevalence of around 70 to 80% in pregnant women. MATERIAL AND METHODS: The aim of the study was to analyse the foetal outcome in the hospitalised pregnant women with severe anaemia. This is a prospective study carried out at maternity ward of Government G eneral H ospital, Kurnool of Andhra Pradesh, India over a period of one year from October 2007 to September 2008. RESULTS: Total of 9731 deliveries occurred during the study period, 282 (2.89 % were severely anaemic at the time of delivery. Majority of the women w ere of 20 - 24 years age (68.4% with second gravidas 37.5%, term gestation 52.1%, preterm deliveries 47.9%, lower socio - economic status 87.6% and Unbooked cases 67.4% and low birth weight in 53.2% cases, intra uterine growth retardation and intra uterine foetal death contributes to 12.8% and 16.7% cases respectively. A total of 36 (12.8% neonates required admission in neonatal intensive care unit and 16(5.7% of them died. CONCLUSION: Severe anaemia during pregnancy has adverse perinatal outcome in the fo rm of low birth weight, preterm birth, intrauterine growth retardation and intrauterine death. Regular iron supplementation during the antenatal period, management of anaemia and improving the nutritional status of the mother will improve the adverse neona tal outcome and decreases perinatal morbidity and mortality.

  5. Inter- and Intrafractional Tumor and Organ Movement in Patients With Cervical Cancer Undergoing Radiotherapy: A Cinematic-MRI Point-of-Interest Study

    International Nuclear Information System (INIS)

    Purpose: Internal tumor and organ movement is important when considering intensity-modulated radiotherapy for patients with cancer of the cervix because of the tight margins and steep dose gradients. In this study, the internal movement of the tumor, cervix, and uterus were examined using serial cinematic magnetic resonance imaging scans and point-of-interest analysis. Methods and Materials: Twenty patients with Stage IB-IVA cervical cancer underwent pelvic magnetic resonance imaging before treatment and then weekly during external beam radiotherapy. In each 30-min session, sequential T2-sagittal magnetic resonance imaging scans were obtained. The points of interest (cervical os, uterine canal, and uterine fundus) were traced on each image frame, allowing the craniocaudal and anteroposterior displacements to be measured. The mean displacements and trends were analyzed using mixed linear models. Prediction intervals were calculated to determine the internal target margins. Results: Large interscan motion was found for all three points of interest that was only partially explained by the variations in bladder and rectal filling. The intrascan motion was much smaller. Both inter- and intrascan motion was greatest at the fundus of the uterus, less along the canal, and least at the cervical os. The isotropic internal target margins required to encompass 90% of the interscan motion were 4 cm at the fundus and 1.5 cm at the os. In contrast, smaller margins of 1 cm and 0.45 cm, respectively, were adequate to encompass the intrascan motion alone. Conclusion: Daily soft-tissue imaging with correction for interfractional motion or adaptive replanning will be important if the benefits of intensity-modulated radiotherapy are to be maximized in women with cervical cancer

  6. Quality of life assessment in advanced non-small-cell lung cancer patients undergoing an accelerated radiotherapy regimen: report of ECOG study 4593

    International Nuclear Information System (INIS)

    Purpose: To prospectively evaluate the quality of life (QOL) before, at completion, and after therapy for patients receiving an accelerated fractionation schedule of radiotherapy for advanced, unresectable non-small-cell lung cancer in a Phase II multi-institutional trial. Methods and Materials: The Functional Assessment of Cancer Therapy-Lung (FACT-L) patient questionnaire was used to score the QOL in patients enrolled in the Eastern Cooperative Oncology Group Phase II trial (ECOG 4593) of hyperfractionated accelerated radiotherapy in non-small-cell lung cancer. Radiotherapy (total dose 57.6 Gy in 36 fractions) was delivered during 15 days, with three radiation fractions given each treatment day. The protocol was activated in 1993, and 30 patients had accrued by November 1995. The FACT-L questionnaire was administered at study entry (baseline), on the last day of radiotherapy (assessment 2), and 4 weeks after therapy (assessment 3). The FACT-L includes scores for physical, functional, emotional, and social well-being (33 items), and a subscale of lung cancer symptoms (10 additional items). The summation of the physical, functional, and lung cancer symptom subscales (21 items) constitutes the Trial Outcome Index (TOI), considered the most clinically relevant outcome measure in lung cancer treatment trials. Results: The FACT-L completion rates at the designated study time points were as follows: baseline, 30 of 30 (100%); assessment 2, 29 (97%) of 30; and assessment 3, 24 (80%) of 30. At treatment completion, statistically significant declines in QOL scores were noted, compared with baseline for physical and functional well-being. Emotional well-being scores improved at both assessment 2 and assessment 3. The physical and functional scores returned approximately to baseline values at assessment 3. The change in TOI score was evaluated as a function of the clinical response to treatment, toxicity grade, and survival; no clear association was noted. A trend for the

  8. Iron deficiency anaemia in Sri Lanka

    International Nuclear Information System (INIS)

    The commonest cause of nutritional anaemia in the Sri Lankan population is iron deficiency. The diets of the population belonging to the lower socio-economic groups contain little food of animal origin. Thus, their diets are deficient in easily absorbable (haem) iron; and are also heavily cereal-based. Therefore interference in the absorption of dietary iron also occurs. Iron-deficiency anaemia is not restricted to the so-called ''vulnerable groups'' in Sri Lanka, however, their greater demands make the problem not only commoner but also more severe. Among pregnant and lactating women anaemia is often associated with folate deficiency. It must also be noted that the low availability of dietary iron is compounded in large population groups. Malaria, presently raging on an epidemic scale is also a major contributory factor to the incidence of anaemia. The purpose of this study was to examine the iron status of pre-school children and pregnant women; to establish normal levels of biochemical indices at different trimesters; to record the effect of iron supplementation during pregnancy; and to record the bioavailability of iron from weaning foods and common adult diets. 6 figs, 14 tabs

    Full Text Available Abstract Background Cancer is one of the major health issues worldwide. An increasing number of cancer patients are offered treatment with surgery, chemotherapy and radiotherapy. Traditional Chinese medicine (TCM is one of the most common complementary therapies offered to cancer patients in Taiwan. We designed a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy of TCM in patients with cancer. Methods/design In this study, inclusion criteria are postoperative patients with histologically confirmed cancer within 3 years who are undergoing chemotherapy or radiotherapy, more than 18 years old, have given signed informed consent, have the ability to read Chinese, and the ability for oral intake. Exclusion criteria include being pregnant, breast feeding, having completed chemotherapy or radiotherapy, brain metastasis with Eastern Cooperative Oncology Group (ECOG performance status of two to four, delusion or hallucinations, acute infection, and have received medications under other clinical trials. The patients were separated into an intervention group (Shen-Mai-San, SMS and a placebo group for four weeks using a randomized, double-blind procedure. The European Organization for Research and Treatment of Cancer (EORTC Quality of Life questionnaire (QOL-C30 was used to evaluate the quality of life. General data, hemoglobin (Hb, hematocrit (Hct, glutamic-oxalacetic transaminase (GOT, glutamic-pyruvic transaminase (GPT, blood urea nitrogen (BUN, creatinine, carcinoembryonic antigen (CEA, TCM diagnosis data and heart rate variability (HRV were also recorded. These data were collected at baseline, two weeks and four weeks after receiving medication. The patients were prescribed granules which contained therapeutic medicines or placebo.

  10. A randomized phase III prospective trial of bethanechol to prevent mucositis, candidiasis, and taste loss in patients with head and neck cancer undergoing radiotherapy. A secondary analysis

    International Nuclear Information System (INIS)

    The aim of this study was to determine the impact of bethanechol administration concomitant to radiotherapy (RT) on oral mucositis, candidiasis and taste loss. We performed a secondary analysis of a previously conducted prospective randomized trial which evaluated the effect of bethanechol on salivary gland dysfunction before, during, and after RT for head and neck cancer (HNC), in comparison to artificial saliva. Mucositis, candidiasis and taste loss were analyzed in 36 patients. Mucositis was scored using the World Health Organization (WHO) method; candidiasis was diagnosed by means of clinical examination, whereas taste loss was assessed by the patients' subjective report of absence of taste. No significant differences were observed between groups in relation to frequency and severity of mucositis or frequency of candidiasis and taste loss. In conclusion, bethanechol does not appear to reduce the incidence of mucositis, candidiasis, and taste loss when administered during RT. (author)

  11. FDG-PET-Detected Extracranial Metastasis in Patients with Non-Small Cell Lung Cancer Undergoing Staging for Surgery or Radical Radiotherapy

    International Nuclear Information System (INIS)

    The prognostic significance of extracranial distant metastasis detected by positron emission tomography (PET) was investigated in patients with non-small cell lung cancer (NSCLC). Forty-two patients staged with 18F-fluorodeoxyglucose-PET-detected distant metastasis before planned surgery (n=7) or radical radiotherapy (RT)/chemoradiotherapy (n=35) for NSCLC were identified from a prospective database. The influence of metastasis number and other prognostic factors was investigated using Cox's regression analysis. Treatment after PET included surgery (n=2), radical RT (n =5), palliative RT (n=25), chemotherapy (n=8) or supportive care (n=2). All but 4 patients had died by the last follow-up. Median survival was 9 months overall, 12 months for 27 patients with single PET-detected metastasis and 5 months for 15 patients with >1 metastasis (p=0.009). It was found that the Eastern Cooperative Oncology Group performance status (p=0.027) but not pre-PET stage, weight loss or metastasis site correlated with survival. PET-detected metastatic tumor burden appeared to influence survival and should be evaluated as a prognostic factor in NSCLC

  12. Increasing the effectiveness of hyperbaric oxygen in enhancing tumor oxygenation: Effect of perfluorochemical emulsion and moderate anaemia

    International Nuclear Information System (INIS)

    Attempts were made to increase the effectiveness of HBO in overcoming tumor hypoxia. Tumor blood flow and O/sub 2/ content were modified by inducing moderate anaemia and giving a perfluorochemical emulsion (PFC-E). Mice were anaesthetized with Ketamine and Diazepam. The PFC-E, FC-43 (0.35 ml/25 g mouse), given iv 1-2 h before irradiation, produced a favourable effect on regrowth delay in those mice treated with HBO. A 25 Gy dose produced a significantly longer regrowth delay (p<0.01) of 44 days in PFC-treated mice compared with a delay of 29 days for mice treated with HBO alone. O/sub 2/ toxicity was observed in some anesthetized mice, with or without PFC-E. Attempts were made to increase the O/sub 2/ sensitization afforded by FC-43/HBO/anaesthesia. Blood viscosity was reduced by inducing a moderate level of acute anaemia by the administration of a single of acute anaemia by the administration of a single ip injection of Phenylhydrazine HCl (40 mg/kg). This reduced the haematocrit from 42% to 32%. Tumour regrowth delay after 25 Gy was significantly reduced (p<0.02) from 44 to 37.3 days be anaemia. PFC's may prove the be useful adjuncts to radiotherapy. However, it must be established that they have no adverse effects and that normal tissue radiosensitivity is not enhanced

  13. Differentiation of irradiation and cetuximab induced skin reactions in patients with locally advanced head and neck cancer undergoing radioimmunotherapy: the HICARE protocol (Head and neck cancer: ImmunoChemo and Radiotherapy with Erbitux) – a multicenter phase IV trial

    International Nuclear Information System (INIS)

    In order to improve the clinical outcome of patients with locally advanced squamous cell carcinoma of the head and neck (LASCCHN) not being capable to receive platinum-based chemoradiation, radiotherapy can be intensified by addition of cetuximab, a monoclonal antibody that blocks the epidermal growth factor receptor (EGFR). The radioimmunotherapy with cetuximab is a feasible treatment option showing a favourable toxicity profile. The most frequent side effect of radiotherapy is radiation dermatitis, the most common side effect of treatment with cetuximab is acneiform rash. Incidence and severity of these frequent, often overlapping and sometimes limiting skin reactions, however, are not well explored. A clinical and molecular differentiation between radiogenic skin reactions and skin reactions caused by cetuximab which may correlate with outcome, have never been described before. The HICARE study is a national, multicenter, prospective phase IV study exploring the different types of skin reactions that occur in patients with LASCCHN undergoing radioimmun(chemo)therapy with the EGFR inhibitor cetuximab. 500 patients with LASCCHN will be enrolled in 40 participating sites in Germany. Primary endpoint is the rate of radiation dermatitis NCI CTCAE grade 3 and 4 (v. 4.02). Radioimmunotherapy will be applied according to SmPC, i.e. cetuximab will be administered as loading dose and then weekly during the radiotherapy. Irradiation will be applied as intensity-modulated radiation therapy (IMRT) or 3D-dimensional radiation therapy. The HICARE trial is expected to be one of the largest trials ever conducted in head and neck cancer patients. The goal of the HICARE trial is to differentiate skin reactions caused by radiation from those caused by the monoclonal antibody cetuximab, to evaluate the incidence and severity of these skin reactions and to correlate them with outcome parameters. Besides, the translational research program will help to identify and confirm novel

  14. Anaemia and other blood diseases induced by radiation

    International Nuclear Information System (INIS)

    The growing interest in the effects of radiation on blood formation is explained not only by the fact that haemopoietic tissue can be damaged in the event of accidents, but also by the fact that depression of medullary haemopoiesis is often a limiting factor in radiotherapy for various malignant diseases, in particular leukosis. The degree of cell alteration in the peripheral blood resulting from different types of exposure to ionizing radiation depends to a large extent on the lifetime of the cells since in irradiation it is primarily the balance between utilization and production of new cells that is disrupted. In animals that survive exposure to lethal doses of radiation a notable drop in the number of erythrocytes has been observed between the 10th and 30th days after irradiation. The most pronounced anaemia usually appears between the 15th and 20th days. In animals that do not survive a significant drop in the number of erythrocytes takes place the day before or the day on which death occurs. The decrease in the number of red blood cells is due mainly to a drop in their production, to increased destruction of erythrocytes and to haemorrhage

  15. A dosimetric comparison of three plans in simultaneous integrated boost intensity-modulated radiotherapy in cervical esophageal carcinoma undergoing prophylactic lymphatic irradiation

    International Nuclear Information System (INIS)

    Objective: To evaluate the optimized simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) plans in cervical esophageal carcinoma underwent prophylactic lymphatic irradiation. Methods: Six patients with cervical esophageal carcinoma were studied.The gross tumor volume (GTV) and clinical target volume (CTV) (including bilateral mid-lower neck and supraclavicular lymph drainage regions, upper mediastinal lymph drainage regions) were delineated on sim-CT images, GTV and CTV were uniformly expanded by 5 mm to create PGTV and PTV. Five fields (5F), 7F and 9F SIB-IMRT plans were designed. The prescribed doses to PGTV and PTV were 66 Gy and 60 Gy in 30 fractions respectively. The parameters of dose-volume histograms in three groups planning were compared. Results: The values of conformity index (CI) of PGTV were 0.56, 0.62 and 0.69 (F =6.22, P<0.01), the V66 with 88.24%, 95.03% and 94.91% (F=4.39, P<0.05) and D95 with 6539.67, 6601.83 and 6602.00 cGy (F=4.46, P<0.05) in 5F, 7F and 9F SIB-IMRT plans. The values of CI, V66 and D95 of PTV were 0.80, 0.85 and 0.87 (F=11.29, P<0.01), with 91.64%, 94.05% and 95.06% (F=4.10, P<0.05) and with 5934.00, 5987.17 and 6006.33 cGy (F=4.01, P<0.05). The values of maximal dose of spinal cord were 4707.17, 4497.83 and 4357.00 cGy (F=11.26, P<0.011) in 5F, 7F and 9F SIB-IMRT plans. The values of all dosimetric parameters about PGTV and PTV were same in 7F and 9F SIB-IMRT plans (all P>0.05). Conclusion: 7F-SIB-IMRT plan is best one scheme for cervical esophageal carcinoma underwent prophylactic lymphatic irradiation. (authors)

  16. The clinical and radiological features of Fanconi's anaemia pictorial review

    International Nuclear Information System (INIS)

    Fanconi's anaemia is a severe refractory anaemia, associated with congenital malformations in approximately two-thirds of cases. Although these malformations may involve every organ system, suggestive dysmorphic features include growth retardation, radial ray deformities and urinary malformations. These malformations are not specific for Fanconi's anaemia, but should be recognized during pregnancy, or later in childhood, and suggest the possibility of inherited haematopoiesis disorders.

    2010-01-15

    Erythropoietin (E.P.O.) is a glycoprotein hormone. This hormone is a growth factor for red blood cells precursors in the bone marrow. The decrease of oxygen partial pressure, a reduced number of erythrocytes caused by bleeding or excessive destruction, or increased tissues oxygen requirements lead to increased secretion of E.P.O.. Its action takes place on bone marrow erythroblastic cells through specific receptors. E.P.O. stimulates the proliferation of red cell precursors stem cells in the bone marrow, thus increasing their production in one to two weeks. The effectiveness of E.P.O. at increasing haemoglobin and improving patients quality of life has been demonstrated by several studies. However, its use in radiotherapy remains controversial. While tumour hypoxia caused by anaemia is a factor of radio resistance and thus a source of local failure, tumour expression of E.P.O. receptors presents a significant risk for tumour progression and neo-angiogenesis, which would be increased during the administration of E.P.O.. The purpose of this article is to answer the question: is there a place for E.P.O. in combination with radiotherapy in the management of cancer?

    A total of 8260 children between the ages of 6-59 months were analyzed to identify the risk factors associated with childhood anaemia in Ethiopia. The overall mean (SD/standard deviation) haemoglobin (Hgb) level among the under-five children was 10.7 (2.2) g/dl and 50.3% were anaemic. Childhood anaemia demonstrated an increasing trend with maternal anaemia levels of mild, moderate and severe anaemia: odds ratio of 1.82, 2.16 and 3.73 respectively (p< 0.01). Children whose mothers had no formal education were 1.38 times more likely to be anaemic (p<0.01). The poorest and poorer wealth index groups had 1.52 and 1.25 increased odds of childhood anaemia respectively (p< 0.01). Childhood anaemia in Ethiopia is a severe public health problem. Maternal anaemia and socio-economic status were found to be associated with anaemia in children. A holistic approach of addressing mothers and children is of paramount importance. PMID:24069773

    Full Text Available Background: Sickle cell anaemia is an inherited disease in which the red blood cells become rigid and sticky, and change from being disc-shaped to being crescent-shaped. The change in shape is due to the presence of an abnormal form of haemoglobin. This results in severe pain and damage to some organs. Aim and Objective: The study was carried out to determine the levels of cytokine in sickle cell anemia. Material and Methods: Thirty confirmed sickle cell patients in steady state (HbSS-SS and thirty persons with normal haemoglobin (HbAA as well as sixteen sickle cell disease in crises (HbSS-cr between the ages of 15 to 30 years were selected in this study. Cytokines including interleukin 1 beta (IL- 1β, interleukin 2 (IL- 2, interleukin (IL-6, tumour necrosis factor alpha (TNF-α, and interferon gamma (IFN- λ were measured by commercially available ELISA kits. Results: The results obtained showed that the levels of TNF-α and IL-6 in sickle cell anaemia patients in crisis were significantly elevated when compared with sickle cell in steady state (P<0.05. Similarly, the levels of IL-1β, IL-6, and IFN- λ were significantly increased in sickle cell anaemia stable state when compared to HbAA subjects (P<0.05. Conclusion: This may probably implies that cytokine imbalance is implicated in the pathogenesis of sickle cell crisis. Also, cytokines could be used as an inflammatory marker as well as related marker in disease severity and hence therapeutic intervention.

  2. Iron in haemoglobinopathies and rare anaemias

    Full Text Available Iron overload in haemoglobinopathies and rare anaemias may develop from increased iron absorption secondary to hepcidin suppression, and/or from repeated blood transfusions. While the accumulation of body iron load from blood transfusion is inevitable and predictable from the variable rates of transfusion in the different conditions, there are some important differences in the distribution of iron overload and its consequences between these. Transfusion-dependent thalassaemia (TDT is the best described condition in which transfusional overload occurs. Initially iron loads into macrophages, subsquently hepatocytes, and then the endocrine system including the anterior pituiatry and finally the myocardium. The propensity to extrahepatic iron spread increases with rapid transfusion and with inadequate chelation therapy but there is considerable interpatient and interpopulation variability in this tendency. The conduits though which iron is delivered to tissues is through non transferrin iron species (NTBI which are taken into liver, endocrine tissues and myocardium through L-type calcium channells and possibly through other channells. Recent work by the MSCIO group1 suggests that levels of NTBI are determined by three mechanisms: i increasing with iron overload; ii increasing with ineffective erythropoieis; iii and decreasing when level of transferrin iron utilisation is high. In TDT all three mechanisms increase NTBI levels because transferrin iron utilisation is suppressed by hypertransfusion. It is hypothesized that the transfusion regimen and target mean Hb may have a key impact on NTBI levels because high transfusion regimes may suppress the ‘sink’ effect of the erythron though decreased clearance of transferrin iron. In sickle cell disease (SCD without blood transfusion the anaemia results mainly from haemolysis rather than from ineffective erythropoiesis.2 Thus there is a tendency to iron depletion because of urinary iron loss from

    The Fanconi anaemia pathway repairs DNA interstrand crosslinks (ICLs) in the genome. Our understanding of this complex pathway is still evolving, as new components continue to be identified and new biochemical systems are used to elucidate the molecular steps of repair. The Fanconi anaemia pathway uses components of other known DNA repair processes to achieve proper repair of ICLs. Moreover, Fanconi anaemia proteins have functions in genome maintenance beyond their canonical roles of repairing ICLs. Such functions include the stabilization of replication forks and the regulation of cytokinesis. Thus, Fanconi anaemia proteins are emerging as master regulators of genomic integrity that coordinate several repair processes. Here, we summarize our current understanding of the functions of the Fanconi anaemia pathway in ICL repair, together with an overview of its connections with other repair pathways and its emerging roles in genome maintenance.

    Full Text Available Background: Nutritional anaemia in pregnant women is one of the India’s major public health problems, despite the fact that this problem is largely preventable & easily treatable. Objectives: 1.To determine the prevalence of anaemia in pregnant women. 2. To assess the epidemiological determinants of anaemia in pregnancy. Methodology: A descriptive case series study was conducted among the pregnant women from second trimester onwards from urban field practice area from 1st March 2010 to 31st July 2010 by using pre-designed, pre-tested, structured schedule. Haemoglobin estimation was done by Sahli’s method & anaemia was graded according to WHO criteria. Statistical analyses were done by percentages and proportions, Mean and Standard Deviation (S.D, Chi-square test. Results: A high prevalence (82.9% of anaemia (Haemoglobin - < 11.0gm/dl was observed among 228 pregnant women. Majority (50.4% had moderate degree of anaemia (Haemoglobin - 7.0 to 10.0 gm/dl and 7.0% had severe anaemia (Haemoglobin - < 7.0 gm/dl. Severity of anaemia was more in 26 years of age, from nuclear families, educated upto secondary level, having vegetarian diet, parity two or more & those in third trimester with two or more abortions, although statistically not significant. However, anaemia prevalence was significantly higher among those subjects from below Class IV socio-economic status, those with less than two years of spacing between previous and index pregnancies & with less than two months IFA tablet consumption. Conclusion: A very high prevalence of anaemia in pregnancy needs mandatory regular supply of IFA tablets to adolescent and pregnant women from 4th month onwards till 3-6 months post-partum along with correction of other nutritional deficiencies and timely intervention for reducing the burden of related diseases.

    Purpose: Stereotactic ablative radiotherapy (SABR) for primary kidney cancer often involves the use of high-energy photons combined with a large number of monitor units. While important for risk assessment, the additional neutron dose to untargeted healthy tissue is not accounted for in treatment planning. This work aims to detect out-of-field neutrons in vivo for patients undergoing SABR with high-energy (>10 MV) photons and provides preliminary estimates of neutron effective dose. Methods: 3 variations of high-sensitivity LiF:Mg,Cu,P thermoluminescent dosimeter (TLD) material, each with varying {sup 6}Li / {sup 7}Li concentrations, were used in custom-made Perspex holders for in vivo measurements. The variation in cross section for thermal neutrons between Li isotopes was exploited to distinguish neutron from photon signal. Measurements were made out-of-field for 7 patients, each undergoing 3D-conformal SABR treatment for primary kidney cancer on a Varian 21iX linear accelerator. Results: In vivo measurements show increased signal for the {sup 6}Li enriched material for patients treated with 18 MV photons. Measurements on one SABR patient treated using only 6 MV showed no difference between the 3 TLD materials. The out-of-field photon signal decreased exponentially with distance from the treatment field. The neutron signal, taken as the difference between {sup 6}Li enriched and {sup 7}Li enriched TLD response, remains almost constant up to 50 cm from the beam central axis. Estimates of neutron effective dose from preliminary TLD calibration suggest between 10 and 30 mSv per 1000 MU delivered at 18 MV for the 7 patients. Conclusion: TLD was proven to be a useful tool for the purpose of in vivo neutron detection at out-of-field locations. Further work is required to understand the relationship between TL signal and neutron dose. Dose estimates based on preliminary TLD calibration in a neutron beam suggest the additional neutron dose was <30 mSv per 1000 MU at 18 MV.

    Full Text Available Abstract Introduction Unexplained anaemia is a rare mode of presentation for prolactinoma. We describe a case of a man, with chronic anaemia ascribed to old age. Six years later, he was evaluated and diagnosed with a prolactinoma and resultant osteoporosis. Prolactinoma in old people may present insidiously with chronic anaemia and osteoporosis with or without sexual dysfunction. Case presentation We describe the case of a 70-year-old Caucasian man who presented with mild anaemia and tiredness. His anaemia was investigated and ascribed to senescence. Endocrine causes were not considered or tested for. Six years later, he was again referred. Reassessment and direct questioning revealed long-standing sexual dysfunction. It was also discovered that our patient had fractured his radius twice, with minor trauma, during the preceding year. His serum prolactin was massively increased and a magnetic resonance imaging (MRI scan of the head demonstrated a pituitary mass consistent with a prolactinoma. Dual X-ray absorptiometry revealed osteoporosis. Treatment of the prolactinoma led to a reduction in his serum prolactin with a rise in his haemoglobin to normal levels. This suggested that the prolactinoma was present during the initial presentation and was the cause of his anaemia. Conclusion This case highlights the importance of fully evaluating and investigating unexplained anaemia in older people and that endocrine causes should be considered. Osteoporosis also requires evaluation with secondary causes considered.

    Full Text Available Abstract Background Anaemia is an important problem amongst young children living in rural India. However, there has not previously been a detailed study of the biological aetiology of this anaemia, exploring the relative contributions of iron, vitamin B12, folate and Vitamin A deficiency, inflammation, genetic haemoglobinopathy, hookworm and malaria. Nor have studies related these aetiologic biological factors to household food security, standard of living and child feeding practices. Barriers to conducting such work have included perceived reluctance of village communities to permit their children to undergo venipuncture, and logistical issues. We have successfully completed a community based, cross sectional field study exploring in detail the causes of anaemia amongst young children in a rural setting. Methods and design A cross sectional, community based study. We engaged in extensive community consultation and tailored our study design to the outcomes of these discussions. We utilised local women as field workers, harnessing the capacity of local health workers to assist with the study. We adopted a programmatic approach with a census rather than random sampling strategy in the village, incorporating appropriate case management for children identified to have anaemia. We developed a questionnaire based on existing standard measurement tools for standard of living, food security and nutrition. Specimen processing was conducted at the Primary Health Centre laboratory prior to transport to an urban research laboratory. Discussion Adopting this study design, we have recruited 415 of 470 potentially eligible children who were living in the selected villages. We achieved support from the community and cooperation of local health workers. Our results will improve the understanding into anaemia amongst young children in rural India. However, many further studies are required to understand the health problems of the population of rural India, and

    International Nuclear Information System (INIS)

    Objectives: To determine the frequency of anaemia in married women in Jutial, and to find out the relationship of risk factors of anaemia with levels of anaemia. Study Design: Cross-sectional study. Place and Duration of Study: Household survey carried out in Jutial, Gilgit 1st February 2008 to 30th April 2009. Patients and Method: Interview administered questionnaire along with blood sample collection using sterilized disposable syringes was used in this study on a total of 382 randomly selected, willing, married, non-pregnant, non-lactating women with one or more children. Results were considered significant if r-value was more than 0.5 with p-value less than 0.05. Results: Clinical analysis of the blood samples showed that the average haemoglobin (Hb) level was 12.8 g/dl. According to WHO standards, no woman had severe anaemia with Hb level below 7 g/dl. Majority of the women (77.5%) had normal Hb >= 12 g/dl. The calculated anaemia frequency of 22.5% was found to be little lower than that of national anaemia frequency of around 29 to 33%. Conclusion: Frequency of anaemia 22.5% can be attributed to good education system in Northern Area and the awareness of people towards health concerns. Another reason can be the initiatives by different NGOs working in the area specially Aga Khan Foundation to eradicate anaemia by developing a vast network of health facilities. Further research on the native foods, their extract nutritional values / iron contents and any special foods at higher altitudes may be more than 1500 meters can open new horizon to our understanding of anaemia in the northern areas.

    Fanconi's anaemia (FA) is an autosomal recessive disorder that is clinically characterized by aplastic anaemia, congenital malformations of the renal, cardiac, skeletal and skin structures, and an increased predisposition to malignancies. Patients with FA often present with bleeding and infection, which are symptoms related to thrombocytopenia and neutropenia. There are few reports of the oral manifestations of FA. We describe oral aphthous ulcerations in two siblings with FA. There was a rapid improvement and healing of ulcers after blood transfusions and increased haemoglobin levels. This may support the role of severe anaemia in oral ulcerations. PMID:15139958

    Purpose: patients undergoing radiotherapy have physical and psychological symptoms related to the underlying disease and the treatment. In order to give the best possible support to the patients, more knowledge about the amount and the changing of distress in the course of radiotherapy is of essentially importance. Methods: The distress was measured in a consecutive sample of cancer patients (n=82) undergoing radiotherapy. Each patient was given the EORTC-QLQ-C30, the HADS and a special questionnaire which ascertain radiotherapy-specific items before starting the radiotherapy, at the onset of radiotherapy, in the third week of radiotherapy and 3 weeks after the end of radiotherapy. Results: within the first week of treatment the psychological distress of the patients is increasing; 98.8 % of the patients are 'moderate distressed', 46 % 'severe distressed'. General physical symptoms seem not to be affected by the radiotherapy, there is no changing. The distress caused by the organization of the radiotherapy is...

    Masking of the macrocytic expression of megaloblastic anaemia (MA) by coexisting thalassaemia, iron deficiency and chronic illness has been widely reported. We described the haematological and clinical features of 20 Chinese patients with MA presenting with mean corpuscular volume (MCV) values of haemoglobin, MCV, red cell distribution width (RDW), reticulocyte index, platelet count and serum bilirubin. All provided clues to maturation disorders within the marrow. A decision flowchart for the diagnosis of MA without macrocytosis was proposed. In the studied population, by using the parameters of haemoglobin or = 16% and reticulocyte index peripheral blood smear examination in the diagnostic procedures for such patients, as well as the importance of paying attention to patients' medical history, racial background and previous MCV value.

    Full Text Available Abstract. The aim of the investigation was to study the immunological characteristics of RA patients with anaemia. Clinical and laboratory data including the percentage of the main lymphocyte subclasses, phagocyte and DTH-effector activity, serum concentration of immunoglobulins, the percentage of cells producing IFNγ and/or IL-4 and percent of monocytes producing TNF. We revealed some significant clinical, laboratory and immunological differences between RA patients and healthy donors and between patients with and without anaemia. Our data demonstrate RA anemic patients to have more severe disorders than patients without anaemia. We also revealed some significant immunological differences between RA patients and healthy donors and between patients with and without anaemia, including percent of cells producing IFNγ and/or IL-4. Our data permit to conclude that RA patients have many different immunological disturbances, more severe in anaemic patients.

    Full Text Available Abstract Introduction Angiolipomas are frequently observed benign tumours. They have a typical vascular component and are often located in subcutaneous tissues, and more rarely, in the gastrointestinal tract. Case presentation We report an uncommon case of an angiolipoma found in the lower portion of the small bowel of an 80-year-old man who was undergoing evaluation for chronic anaemia. A standardised diagnostic pathway was followed. Endoscopic and radiological findings were negative. The diagnosis was finally established with the aid of capsule endoscopy. The case we report is the first in the literature of an angiolipoma without specific painful symptoms. In fact, the patient did not complain of abdominal pain or alvus changes, and abdominal examination did not suggest an expansive process. The endoscopic study performed with the capsule identified the lesion as the cause of the ingravescent anaemia. Intra-operative histological examination of the lesion made it possible to avoid a major surgical procedure and assured a short postoperative course for the patient. Conclusion This report focuses on the importance of correct pre- and/or intra-operative histological diagnosis in order to offer the best therapeutic choice. An angiolipoma was suspected in this case, even though they are rarely located in the ileum.

    Full Text Available Abstract Introduction Iron deficiency is the most common cause of anaemia worldwide. Pica, the ingestion of substances that are inappropriate for consumption, is associated with iron deficiency and may be under-diagnosed. Case presentation A 34-year-old woman presented with iron deficiency anaemia refractory to treatment for more than a decade. The clinical presentation, endoscopic findings and laboratory investigations were consistent with pica. Subsequent geophysical analysis confirmed that the ingested material was kaolin, a negatively charged silicate. Conclusion Prolonged unexplained iron deficiency anaemia should prompt clinicians to remember and inquire about pica. In our patient, this would have averted numerous unnecessary investigations and prevented a decade-long suffering.

    Full Text Available BACKGROUND: Severe anaemia is a major cause of morbidity and mortality in African children. The aetiology is multi-factorial, but interventions have often targeted only one or a few causal factors, with limited success. METHODS AND FINDINGS: We assessed the contribution of different pathophysiological mechanisms (red cell production failure [RCPF], haemolysis and blood loss to severe anaemia in Malawian children in whom etiological factors have been described previously. More complex associations between etiological factors and the mechanisms were explored using structural equation modelling. In 235 children with severe anaemia (haemoglobin<3.2 mMol/L [5.0 g/dl] studied, RCPF, haemolysis and blood loss were found in 48.1%, 21.7% and 6.9%, respectively. The RCPF figure increased to 86% when a less stringent definition of RCPF was applied. RCPF was the most common mechanism in each of the major etiological subgroups (39.7-59.7%. Multiple aetiologies were common in children with severe anaemia. In the final model, nutritional and infectious factors, including malaria, were directly or indirectly associated with RCPF, but not with haemolysis. CONCLUSION: RCPF was the most common pathway leading to severe anaemia, from a variety of etiological factors, often found in combination. Unlike haemolysis or blood loss, RCPF is a defect that is likely to persist to a significant degree unless all of its contributing aetiologies are corrected. This provides a further explanation for the limited success of the single factor interventions that have commonly been applied to the prevention or treatment of severe anaemia. Our findings underline the need for a package of measures directed against all of the local aetiologies of this often fatal paediatric syndrome.

    Cancer-associated microangiopathic haemolytic anaemia (CA-MAHA) is a syndrome characterised by Coombs-negative haemolytic anaemia and thrombocytopenia. It is primarily seen in advanced solid tumours and is distinct from thrombotic thrombocytopenic purpura/haemolytic uraemic syndrome. Diagnosis is often delayed and patients have a high mortality. We present the case of CA-MAHA in a patient with metastatic breast cancer treated successfully with early initiation of chemotherapy. In addition, we report longitudinal laboratory evaluation of circulating tumour cells and microparticles and suggest a hypothesis for the mechanism behind CA-MAHA. PMID:26744538

  12. Radioisotopes of iron in investigation of anaemia in malnutrition

    International Nuclear Information System (INIS)

    Iron absorption from a simple breakfast meal by a normal adult was done by the whole body counting system and blood radioactivity measurement. Results seem to be in good agreement and both the methods are found to be standard for measurements of iron absorption from food. In iron deficiency anaemia associated with malnutrition improvement of nutritional condition has been found to increase both haemoglobin level and iron absorption possibly by way of improving the ability of intestinal mucosa to absorb more iron from food and by better utilization of iron by erythropoietic system. Thus improvement of nutritional status is a prerequisite to treatment of iron deficiency anaemia. (author)

    Full Text Available Use of current models of Automated Haematology Analysers help in calculating the haemoglobin contents of the mature Red cells, Reticulocytes and percentages of Microcytic and hypochromic Red cells. This has helped the clinician in reaching early diagnosis and management of Different haemopoietic disorders like Iron Deficiency Anaemia, Thalassaemia and anaemia of chronic diseases. AIM This study is conducted using an Automated Haematology Analyser to evaluate anaemia using the Red Cell and Reticulocyte parameters. Three types of anaemia were evaluated; iron deficiency anaemia, anaemia of long duration and anaemia associated with chronic disease and Iron deficiency. MATERIALS AND METHODS The blood samples were collected from 287 adult patients with anaemia differentiated depending upon their iron status, haemoglobinopathies and inflammatory activity. Iron deficiency anaemia (n=132, anaemia of long duration (ACD, (n=97 and anaemia associated with chronic disease with iron deficiency (ACD Combi, (n=58. Microcytic Red cells, hypochromic red cells percentage and levels of haemoglobin in reticulocytes and matured RBCs were calculated. The accuracy of the parameters was analysed using receiver operating characteristic analyser to differentiate between the types of anaemia. OBSERVATIONS AND RESULTS There was no difference in parameters between the iron deficiency group or anaemia associated with chronic disease and iron deficiency. The hypochromic red cells percentage was the best parameter in differentiating anaemia of chronic disease with or without absolute iron deficiency with a sensitivity of 72.7% and a specificity of 70.4%. CONCLUSIONS The parameters of red cells and reticulocytes were of reasonably good indicators in differentiating the absolute iron deficiency anaemia with chronic disease.

  14. Effects of a dietary intervention on acute gastrointestinal side effects and other aspects of health-related quality of life: A randomized controlled trial in prostate cancer patients undergoing radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To study the effect of a dietary intervention on acute gastrointestinal side effects and other aspects of health-related quality of life (HRQOL) in prostate cancer patients referred to radiotherapy. Materials and methods: A total of 130 patients were randomly assigned to one of two groups: an intervention group (IG, n = 64), instructed to reduce their intake of insoluble dietary fibres and lactose, a standard care group (SC, n = 66), instructed to continue their normal diet. Gastrointestinal side effects and other aspects of HRQOL were evaluated from baseline up to 2 months after completed radiotherapy, using the EORTC QLQ-C30 and QLQ-PR25 and the study-specific Gastrointestinal Side Effects Questionnaire (GISEQ). A scale indicating adherence to dietary instructions was developed from a Food Frequency Questionnaire (FFQ), with lower scores representing better compliance. Descriptive and inferential statistical analyses were conducted. Results: There was an interaction effect between randomization and time in the FFQ Scores (p < 0.001), indicating that both groups followed their assigned dietary instructions. The dietary intervention had no effect on gastrointestinal side effects or other aspects of HRQOL. During radiotherapy, the percentage of patients with bowel symptoms and bloated abdomen was lower in IG compared to SC, but the between-group differences were not statistically significant. During radiotherapy, the percentage of patients with bowel symptoms, urinary symptoms, pain, fatigue and diminished physical and role functioning increased in both groups. Conclusions: The dietary intervention had no effect on gastrointestinal side effects or other aspects of HRQOL. The tendency towards lower prevalence of bowel symptoms in IG may indicate some positive effect of the dietary intervention, but methodological refinements, clearer results and longer follow-up are needed before the value of diet change can be established with certainty.

    Recombinant human erythropoietin (epoetin) has become the standard of care in the treatment of anaemia resulting from cancer and its treatment, and chronic kidney disease. The discovery that erythropoietin and its receptor are located in regions outside the erythropoietic system has led to interest in the potential role of epoetin in other tissues, such as the central nervous system. Animal studies have shown that systemically applied epoetin can cross the blood-brain barrier, where it reduces tissue injury associated with stroke, blunt trauma and experimental autoimmune encephalomyelitis. Pilot studies in humans have shown that epoetin treatment given within 8 h of stroke reduces infarct size and results in a significantly better outcome when compared with placebo treatment. Studies also suggest that epoetin has the potential to improve cognitive impairment associated with adjuvant chemotherapy in patients with cancer. Anaemia is a major factor causing tumour hypoxia, a condition that can promote changes within neoplastic cells that further tumour survival and malignant progression and also reduces the effectiveness of several anticancer therapies including radiotherapy and oxygen-dependent cytotoxic agents. Use of epoetin to prevent or correct anaemia has the potential to reduce tumour hypoxia and improve treatment outcome. Several therapeutic studies in anaemic animals with experimental tumours have shown a beneficial effect of epoetin on delaying tumour growth. Furthermore, clinical observations in patients with multiple myeloma and animal studies have suggested that epoetin has an antimyeloma effect, mediated via the immune system through activation of CD8+ T cells. Therefore, the role of epoetin may go well beyond that of increasing haemoglobin levels in anaemic patients, although additional studies are required to confirm these promising results.

    Sickle cell anaemia (SCA) is one of the commonest chronic hemolytic anaemias in the Sudan; it is a disease with high mortality and morbidity. This study was conducted aiming to observe the clinical pattern of cardiac abnormalities in children with sickle cell anaemia, and to assess the relationship between the cardiac abnormalities and the severity of the disease. The study was conducted in sickle cell disease clinic at Khartoum Children Emergency Hospital. The study group consisted of 289 patients with sickle cell anaemia, age range from 6 months to 18 years. Data were collected using a questionnaire which include full history, clinical examination findings, chest x-rays, and Electro-cardiography. Tachycardia, systolic murmurs, and cardiomegaly were detected in 28%, 61%, and 54% of patients with SCA respectively. Left ventricular dilatation was observed in 51% of the study group, while right ventricular dilatation was observed in 22% of the patients. Left and right atrial dilatations were observed in 16% and 6% of the patients respectively. Contractility, ejection fraction (EF) were found almost always normal in all study subjects. Chamber dilatations were not associated with any abnormality in Left ventricular functions. Hemglobin (Hb) levels correlated negatively with cardiomegaly. Left Ventricular End Diastolic Dimension (LVEDD) correlates negatively with Hb levels and positively with the severity index. Only four patients (1%) had abnormal valves. In conclusion, cardiac abnormalities in patients with SCA correlate with the age of the patients and the severity of the disease. PMID:27493331

  19. The adaptive response of mouse tumours to anaemia and retransfusion

    International Nuclear Information System (INIS)

    Exchange transfusion methods have been developed to alter the haematocrit of tumour-bearing mice. The effects of anaemia and its correction by blood transfusion on the radiosensitivity of two mouse tumours (SCCVII/St and RIF-1) were studied using excision, in vivo/in vitro assay. Acute reduction in haematocrit caused a high degree of radioresistance equivalent to an increase in the hypoxic fractions by factors of 10 (SCCVII/St) and 30 (RIF-1). As the duration of anaemia was prolonged, radioresistance was lost until within about 6 h normal radiosensitivity was observed even though the anaemia persisted. The restoration of the normal haematocrit by red blood cell transfusion after 24 h of anaemia caused increased radiosensitivity equivalent to a reduction in the hypoxic fraction by factors of 5 (SCCVII/St) and 10 (RIF-1), but again the effect was transient and normal radiosensitivity re-established within 24-48 h of retransfusion. Measurements of 14C misonidazole (MISO) binding to RIF-1 tumours after these procedures indicated changes in the number of hypoxic cells which were qualitatively almost identical to those using the cell survival endpoint, leading to the belief that changes in oxygenation were reponsible for the altered radiosensitivity.

    Full Text Available Introduction: Anaemia is associated with increased post-operative morbidity and mortality. We retrospectively assess the relationship between preoperative anaemia and in-hospital mortality in valvular cardiac surgical population. Materials and Methods: Data from consecutive adult patients who underwent valvular repair/ replacement at our institute from January 2010 to April 2014 were collected from hospital records. Anaemia was defined according to WHO criteria (hemoglobin <13g/dl for males and <12g/dl for females. 1:1 matching was done for anemic and non-anemic patients based on propensity for potentially confounding variables. Logistic regression was used to evaluate the relationship between anaemia and in-hospital mortality. MatchIt package for R software was used for propensity matching and SPSS 16.0.0 was used for statistical analysis. Results: 2449 patients undergoing valvular surgery with or without coronary artery grafting were included. Anaemia was present in 37.1% (33.91% among males & 40.88% among females. Unadjusted OR for mortality was 1.6 in anemic group (95% Confidence Interval [95% CI] - 1.041-2.570; p=0.033. 1:1 matching was done on the basis of propensity score for anaemia (866 pairs. Balancing was confirmed using standardized differences. Anaemia had an OR of 1.8 for mortality (95% CI- 1.042 to 3.094, P=0.035. Hematocrit of < 20 on bypass was associated with higher mortality. Conclusion: Preoperative anaemia is an independent risk factor associated with in-hospital mortality in patients undergoing valvular heart surgery.

    Full Text Available Abstract Background Post-transplant anaemia remains a common problem after kidney transplantation, with an incidence ranging from nearly 80% at day 0 to about 25% at 1 year. It has been associated with poor graft outcome, and recently has also been shown to be associated with increased mortality. Our transplant unit routinely administers oral iron supplements to renal transplant recipients but this is frequently accompanied by side effects, mainly gastrointestinal intolerance. Intravenous iron is frequently administered to dialysis patients and we sought to investigate this mode of administration in transplant recipients after noticing less anaemia in several patients who had received intravenous iron just prior to being called in for transplantation. Methods This study is a single-centre, prospective, open-label, randomised, controlled trial of oral versus intravenous iron supplements in renal transplant recipients and aims to recruit approximately 100 patients over a 12-month period. Patients will be randomised to receive a single dose of 500 mg iron polymaltose (intravenous iron group or 2 ferrous sulphate slow-release tablets daily (oral iron group. The primary outcome is time to normalisation of haemoglobin post-transplant. Prospective power calculations have indicated that a minimum of 48 patients in each group would have to be followed up for 3 months in order to have a 90% probability of detecting a halving of the time to correction of haemoglobin levels to ≥110 g/l in iron-treated patients, assuming an α of 0.05. All eligible adult patients undergoing renal transplantation at the Princess Alexandra Hospital will be offered participation in the trial. Exclusion criteria will include iron overload (transferrin saturation >50% or ferritin >800 μg/l, or previous intolerance of either oral or intravenous iron supplements. Discussion If the trial shows a reduction in the time to correction of anaemia with intravenous iron or less side

    Full Text Available Allogeneic blood transfusion (ABT is frequently used as the first therapeutic option for the treatment of acute anaemia in patients with inflammatory bowel disease (IBD, especially when it developed due to gastrointestinal or perioperative blood loss, but is not risk-free. Adverse effects of ABT include, but are not limited to, acute hemolytic reaction (wrong blood or wrong patient, febrile non-hemolytic transfusional reaction, bacterial contamination, transfusion-related acute lung injury, transfusion associated circulatory overload, transfusion-related immuno-modulation, and transmission of almost all infectious diseases (bacteria, virus, protozoa and prion, which might result in increased risk of morbidity and mortality. Unfortunately, the main physiological goal of ABT, i.e. to increase oxygen consumption by the hypoxic tissues, has not been well documented. In contrast, the ABT is usually misused only to increase the haemoglobin level within a fixed protocol [mostly two by two packed red blood cell (PRC units] independently of the patient’s tolerance to normovolemic anaemia or his clinical response to the transfusion of PRC units according to a “one-by-one” administration schedule. Evidence-based clinical guidelines may promote best transfusion practices by implementing restrictive transfusion protocols, thus reducing variability and minimizing the avoidable risks of transfusion, and the use of autologous blood and pharmacologic alternatives. In this regard, preoperative autologous blood donation (PABD consistently diminished the frequency of ABT, although its contribution to ABT avoidance is reduced when performed under a transfusion protocol. In addition, interpretation of utility of PABD in surgical IBD patients is hampered by scarcity of published data. However, the role of autologous red blood cells as drug carriers is promising. Finally, it must be stressed that a combination of methods used within well-constructed protocols

    Full Text Available INTRODUCTION Anaemia is a serious and prominent problem in the developing countries. This study evaluates the prevalence of anaemia in pregnant women attending the outpatient clinic in a semi-urban hospital for a period of six months. MATERIALS AND METHODS Data from a sample of 500 pregnant women was collected and the patients were screened for anaemia on their booking visit in KFMS&R for a period of six months from March-August 2015. Haemoglobin was estimated by cyanmethaemoglobin method using Systronic photocolorimeter on their first antenatal visit. The degree of anaemia was categorised according to ICMR datamild (10-10.99 g/dL, moderate (7-9.99 g/dL, severe (<7 g/dL. RESULTS It was observed that the prevalence of anaemia was 51.8% in the population under study. The prevalence of mild anaemia was 18.53%, that of moderate anaemia was 63.70% and that of severe anaemia was 17.76%. It was also noticed that the prevalence of anaemia was higher in young pregnant women between 17-21 years of age (63.26%. CONCLUSION Anaemia continues to be a major health problem in India and prevention and early diagnosis will significantly reduce maternal and perinatal morbidity and mortality.

    Full Text Available Endurance athletes require a very efficient oxygen transport system for maximal aerobic power during physical work performance. Many studies carried on endurance athletes suggested low levels of red blood cell markers leading to misconception of existence of so called sports anaemia in athletes. Sometimes athletes are on needless iron supplementation and are concern about anaemia. The main objectives of the study were to investigate the red cell population markers and to study the sports anaemia phenomenon in endurance athletes and the underlying responses responsible for ot. 60 male endurance track and field runners age group 18-21 were selected from the local city based club named Vasant Desai Krida Sangh Akola and were compared with the age, height sex matched non athletes students of Govt. Medical College Akola. The seven red blood cell markers were studied from the blood samples taken from the cubital vein under standard conditions. The blood variables for both the groups were analyzed with an automatic cell counter. The mean values of Hb(12.27 gm% +/- 0.782, RBC count in(3.64millions per cu mm+/-0.52, hematocrit ( 41.58 % +/- 1.32, mean corpuscular Hb conc (MCHC 29.49% +/- 1.198 were all very significantly lower ( p<0.0001 as compare to controls. Whereas the plasma volume (58.412% +/- 1.32, Mean Corpuscular volume (MCV 115.06 cu microns+/- 11.54, Mean Hb conc (MCH 33.998 picogms+/- 2.608, were significantly increased in endurance athletes. Though decrease in Hb conc, Low RBC count and less hematocrit in endurance athletes indicate presence of anaemia in them but it’s not a true anaemia as it is also confirmed by MCV, MCH, MCHC values between the two groups. The significant differences between the groups are due to the response to endurance training leading to hemo dilutional anaemia caused by plasma volume expansion which increases the blood volume in endurance athletes helping them for better oxygen supply and aerobic power needed

    The phenotypic expression of sickle cell anaemia varies greatly among patients and longitudinally in the same patient. It influences all aspects of the life of affected individuals including social interactions, intimate relationships, family relations, peer interactions, education, employment, spirituality and religiosity. The clinical manifestations of sickle cell anaemia are protean and fall into three major categories: anaemia and its sequelae;pain and related issues; andorgan failure including infection. Recent studies on the pathogenesis of sickle cell anaemia have centred on the sequence of events that occur between polymerisation of deoxy haemoglobin (Hb) S and vaso-occlusion. Cellular dehydration, inflammatory response and reperfusion injury seem to be important pathophysiological mechanisms. Management of sickle cell anaemia continues to be primarily palliative in nature, including supportive, symptomatic and preventative approaches to therapy. Empowerment and education are the major aspects of supportive care. Symptomatic management includes pain management, blood transfusion and treatment of organ failure. Pain managment should follow certain priniciples that include assessment, individualisation of therapy and proper utilisation of opioid and nonopioid analgesics in order to acheive adequate pain relief. Blood selected for transfusion should be leuko-reduced and phenotypically matched for the C, E and Kell antigens. Exchange transfusion is indicated in patients who are transfused chronically in order to prevent or delay the onset of iron-overload. Acute chest syndrome is the most common form of organ failure and its management should be agressive, including adequate ventilation, multiple antibacterials and simple or exchange blood transfusion depending on its severity. Preventitive therapy includes prophylactic penicillin in infants and children, blood transfusion (preferably exchange transfusion) in patients with stroke, and hydroxyurea in patients

    Congenital dyserythropoietic anaemia (CDA) is a heterogeneous group of rare genetic disorders that in humans is characterised by ineffective haematopoiesis with morphological abnormalities in erythroid precursor cells and secondary iron overload. In the 1990s, a syndrome of CDA with dyskeratosis and progressive alopecia was reported in Poll Hereford calves in Canada and the USA. We report the clinical and pathological findings in two Poll Hereford calves with this syndrome from separate properties in South Australia. The animals had a variably severe anaemia, associated with abnormal nucleated red blood cells in peripheral blood, and large numbers of rubricytes and metarubricytes with a characteristic nuclear ultrastructure in the bone marrow. Both calves were born with a wiry hair coat and a progressively 'dirty-faced' appearance associated with hyperkeratosis and dyskeratosis (apoptosis). PMID:23186092

    Anaemia of inflammatory disease is a common cause of anaemia in routine veterinary practice. It is most often mild to moderate, normocytic, normochromic and non-regenerative. Shortened red cell life span, inhibition of iron metabolism and impaired bone marrow response to erythropoietin all contribute to its development. Although anaemia of inflammatory disease is a well-known cause of anaemia in dogs and cats, there is a lack of epidemiological information because specific diagnostic criteria have not been established in veterinary species. Anaemia of inflammatory disease is associated with a poor outcome in various disease states in human medicine; however, its clinical significance and treatment in veterinary medicine are not well understood. This review article describes anaemia of inflammatory disease in dogs and cats and considers its potential significance. PMID:27385622

    International Nuclear Information System (INIS)

    To identify the etiological factors responsible for increased incidence of megaloblastic anaemia in district Gilgit. A retrospective analysis of sixty one patients (n=61) was done who were diagnosed as patients of chronic anaemia. They were referred for bone marrow examination. Out of these, twenty two cases (n=22) were diagnosed as megaloblastic anaemia. Serum samples of all the patients were sent to AFIP for estimation of B12 and folate levels. A detailed history with special emphasis on dietary habits was noted. Patients included in the study were either retired Armed Forces personal (n=6) who had been living in district Gilgit for over period of five years. Other patients (n=16) were serving Army personal who had been serving in district Gilgit for over one year. Out of twenty two patients (n=22), only three (n=3, 13.6 %) had poor dietary history. A total of sixteen (n=16, 72.7%) patients had diarrhoea .Out of these sixteen, ten patients (n=10, 62.5%) had vegetative forms of gardia lamblia in their stools specimens. All (n=10) patients, who had giardiasis, had dyspeptic symptoms as their initial complaints. Twenty two serum samples were sent to AFIP for Vit B12 and folate level estimation. A total of seven patients (n=7, 31.8%) had low Vit B12 levels, while one patient (n=1, 4.5 %) had decreased level of both Vit B12 and folate. Chronic giardiasis and dietary insufficiency may be a major cause for increased incidence of megaloblastic anaemia in district Gilgit. (author)

    Background & objectives: Fanconi anaemia (FA) is a syndrome with a predisposition to bone marrow failure, congenital anomalies and malignancies. It is characterized by cellular hypersensitivity to cross-linking agents such as mitomycin C (MMC). In the present study, a new approach was selected to investigate FANCA (Fanconi anaemia complementation group A) gene in patients clinically diagnosed with cellular hypersensitivity to DNA cross-linking agent MMC. Methods: Chromosomal breakage analysis was performed to prove the diagnosis of Fanconi anaemia in 318 families. Of these, 70 families had a positive result. Forty families agreed to molecular genetic testing. In total, there were 27 patients with unknown complementary types. Genomic DNA was extracted and total RNA was isolated from fresh whole blood of the patients. The first-strand cDNA was synthesized and the cDNA of each patient was then tested with 21 pairs of overlapping primers. High resolution melting curve analysis was used to screen FANCA, and LinReg software version 1.7 was utilized for analysis of expression. Results: In total, six sequence alterations were identified, which included two stop codons, two frames-shift mutations, one large deletion and one amino acid exchange. FANCA expression was downregulated in patients who had sequence alterations. Interpretation & conclusions: The results of the present study show that high resolution melting (HRM) curve analysis may be useful in the detection of sequence alteration. It is simpler and more costeffective than the multiplex ligation-dependent probe amplification (MLPA) procedure. PMID:27121516

  13. Hematopoiesis research in aplastic anaemia induced by accidental protracted radiation

    International Nuclear Information System (INIS)

    Over the past few years there have been 2 radiation-related accidents involving a large number of individuals: the April 1986 accident in Chernobyl nuclear power station in the Ukraine and the September 1987 accident in Goiania, Brazil. These 2 radiation-related accidents highlight the major question raised by radiation-induced injury to the haematopoietic system, that is: does a given patient suffer from a reversible or an irreversible haematopoietic stem cell damage ? Although about 350 radiation accidents involving several thousand people are known from the literature, in-depth haematopoiesis analyses of individuals after a radiation-related accident have rarely been reported. In this paper we present the case of a young man with radiation-induced aplasia and compare some biological data to those of 16 normal individuals and of 17 patients with acquired aplastic anaemia. Our patient was clinically and biologically (as assessed by long-term bone marrow culture) indistinguishable from patients with idiopathic acquired aplastic anaemia. Furthermore, therapeutic attitudes in this patient are discussed. In-depth study of such radiation-induced aplastic anaemia cases can shed some light in the understanding of this disease and may help in therapeutic decisions. (author)

  14. Frequency of anaemia in patients with systemic lupus erythematosus at tertiary care hospitals

    International Nuclear Information System (INIS)

    To analyze the frequency and causes of anaemia in systemic lupus erythematosus (SLE) patients attending in department of medicine at tertiary care hospitals. Methods: This retrospective, descriptive and analytical study was planned to analyze the frequency and causes of anaemia in SLE patients attending the department of medicine at (MMC) and (LUMHS) hospitals during the period of Jan 2006 to Nov 2008. The criteria used in this study were from the American College of Rheumatology. Investigations recorded were blood complete picture, absolute values, peripheral smear, and reticulocyte count in all patients of anaemia. These investigations were necessary to analyse the cases of anaemia in SLE. All investigations were not done in all cases. Patients with hypochromic microcytic anaemia were advised to have serum iron and ferritin levels, seven patients with macrocytic anaemia were advised to have direct and indirect coomb's test, LFTs, serum LDH, serum B12 and folate levels. Patients with normochromic and normocytic anaemia were considered to have anaemia of chronic disease. Bone marrow aspiration and Hb electrophoresis were done in two patients with anaemia of chronic disease. Thirty adult patients were included in this study. Special proforma were prepared to record the information from case sheets of patients including basic information, symptomatology and laboratory investigations. Severity and various types of anaemias were recorded. Anaemia was graded according to severity, as mild (Hb 10-12 G/dl), Moderate (Hb 8-10 G/dl) and severe (Hb 1:80; and nineteen (63.33%) patients had anti ds DNA positive, titres >1:10. Conclusion: Haematologic abnormalities are common manifestations in patients with SLE. Most patients exhibit anaemia at some point during their disease course. (author)

    We reviewed the records of antenatal clinic attendees over a period of 9 years to determine the prevalence of anaemia at booking. The laboratory records of 8751 out of a total of 37,506 pregnant women who booked for antenatal care between 2004 and 2013 at the BMSH were reviewed. The effects of maternal age, educational status, parity, gestational age, haemoglobin genotype and infections on the prevalence of anaemia were investigated. The prevalence of anaemia at booking was 69.6%, most of whom had moderate anaemia. Anaemia was significantly prevalent in the 10-19 year age group, and in women with secondary education, in their 2nd trimester and with SS genotype. Anaemia also increased with gestational age, this however was not statistically significant. There was no statistical difference between those who are human immunodeficiency virus (HIV) positive and had anaemia and those who are HIV negative who also had anaemia. This study shows that anaemia in pregnant women is still unacceptably high considering the consequences and despite interventions on the ground to reduce prevalence. There is a need to review the intervention measures with emphasis on programmes that would increase awareness among pregnant women and the general public. PMID:27110932

    The authors evoke some characteristics of the basal cell carcinoma (slow evolution, local morbidity) and report and discuss the case of a giant basal cell trunk carcinoma, associated with several symptoms (pain, bleeding, anaemia), already metastatic at the moment of diagnosis, and locally treated by irradiation. Due to its size and expansion, this carcinoma was considered as inoperable. An external radiotherapy has been performed and resulted in a significant clinical tumour reduction. But the metastatic risk is high in such cases. Radiotherapy is then a therapeutic option for a local treatment with a durable efficiency. Short communication

    Extramedullary haematopoiesis is sometimes encountered in serve anaemia. Rarely, it may cause neurological symptoms, leading to spinal cord or cauda equina compression. Three patients with thalassaemia intermedia, who developed neurological complications, are described. The diagnoses were based on the clinical findings, computed tomography and magnetic resonance imaging. Small doses of radiotherapy (10-20 Gy in 5-10 fractions) relieved symptoms in all of these patients. Our experience supports the role of radiation therapy as a treatment for this complication.

    Anti-tuberculosis drugs seldom cause serious haematological side effects. However, among these drugs, isoniazid and rifampicin, especially when administered intermittently, may very rarely be linked to acute autoimmune haemolytic anaemia. Ethambutol (EMB) can cause dose-related retrobulbar neuritis. In this paper, we present the first reported case of acute fatal autoimmune haemolytic anaemia due to EMB. PMID:27084828

    Late patronage of antenatal care by women in low-resource areas makes timely intervention at correcting anaemia difficult. This study aimed to identify modifiable sociodemographic factors that predict anaemia before commencing antenatal care and make appropriate recommendation. A survey of sociodemographic features and haemoglobin concentrations of 232 women booking for antenatal care was conducted. Anaemia was diagnosed in 119 (51.3%), of which 87 (37.5%) had mild anaemia and 32 (13.8%) were moderately anaemic. There was no severe anaemia. Anaemia was highest among respondents who were 35 years of age, Muslims, of Igbo ethnicity (64.3%), single (55.0%), student/unemployed (58.8%), nulliparous (57.3%) and those who registered at 21 weeks' gestation (54.2%). Only occupation of the woman showed association with anaemia before antenatal care (p 0.007). A personal source of income may reduce anaemia in pregnancy; and it is advisable to have a social welfare package for unemployed pregnant women. PMID:26214716

  9. Fatal cold agglutinin-induced haemolytic anaemia: a case report

    2010-08-01

    Full Text Available Abstract Introduction Cold agglutinin disease usually develops as a result of the production of a specific immunoglobulin M auto-antibody directed against the I/i and H antigens, precursors of the ABH and Lewis blood group substances, on red blood cells. Autoimmune and lymphoproliferative disorders, Mycoplasma pneumoniae and other infections can be associated with the production of cold agglutinins. In its classic presentation with haemolytic anaemia and Raynaud's syndrome, cold agglutinin disease is usually idiopathic. Several factors play a role in determining the ability of a cold agglutinin to induce a haemolytic anaemia such as antibody concentration and temperature range, in particular the highest temperature at which antibodies interact with red blood cells. Case presentation A 48-year-old Caucasian man presented to our hospital with symptoms of extreme asthenia caused by severe anaemia. The transfusion of red blood cells (O Rh-positive, started as prescribed by the emergency guidelines in force without pre-transfusion tests, induced fatal haemolysis because of the presence of high levels of anti-H antibodies in his blood, that reacted with the large amount of H antigen in universal (0 red blood cells. Conclusion Emergency transfusion of universal red blood cells (0 Rh-positive or negative is usually accepted by the international guidelines in force in emergency departments. In this report we describe a rare complication caused by the very high concentration in the recipient of cold agglutinins and the activation of the complement system, responsible for red blood cell lysis and consequent fatal cardiovascular shock. We conclude that emergency transfusion of universal red blood cells (0 Rh-positive or negative may be dangerous and its risk should be assessed against the risk of delaying transfusion until the pre-transfusion tests are completed.

    Purpose: To report our institution's experience using prone positioning for three-dimensional conformal radiotherapy (3D-CRT) to deliver post-lumpectomy whole breast irradiation (WBI) in a cohort of women with large and/or pendulous breasts, to determine the rate of acute and late toxicities and, more specifically, cosmetic outcomes. We hypothesized that using 3D-CRT for WBI in the prone position would reduce or eliminate patient and breast size as negative prognostic indicators for toxicities associated with WBI. Methods and Materials: From 1998 to 2006, 110 cases were treated with prone WBI using 3D-CRT. The lumpectomy, breast target volumes, heart, and lung were contoured on all computed tomography scans. A dose of 45-50 Gy was prescribed to the breast volume using standard fractionation schemes. The planning goals were {>=}95% of prescription to 95% of the breast volume, and 100% of boost dose to 95% of lumpectomy planning target volume. Toxicities and cosmesis were prospectively scored using the Common Terminology Criteria for Adverse Effects Version 3.0 and the Harvard Scale. The median follow-up was 40 months. Results: The median body mass index (BMI) was 33.6 kg/m{sup 2}, and median breast volume was 1396 cm{sup 3}. The worst toxicity encountered during radiation was Grade 3 dermatitis in 5% of our patient population. Moist desquamation occurred in 16% of patients, with only 2% of patients with moist desquamation outside the inframammary/axillary folds. Eleven percent of patients had Grade {>=}2 late toxicities, including Grade 3 induration/fibrosis in 2%. Excellent to good cosmesis was achieved in 89%. Higher BMI was associated with moist desquamation and breast pain, but BMI and breast volume did not impact fibrosis or excellent to good cosmesis. Conclusion: In patients with higher BMI and/or large-pendulous breasts, delivering prone WBI using 3D-CRT results in favorable toxicity profiles and high excellent to good cosmesis rates. Higher BMI was

  12. Psychological and physical distress of cancer patients during radiotherapy

    International Nuclear Information System (INIS)

    Purpose: patients undergoing radiotherapy have physical and psychological symptoms related to the underlying disease and the treatment. In order to give the best possible support to the patients, more knowledge about the amount and the changing of distress in the course of radiotherapy is of essentially importance. Methods: The distress was measured in a consecutive sample of cancer patients (n=82) undergoing radiotherapy. Each patient was given the EORTC-QLQ-C30, the HADS and a special questionnaire which ascertain radiotherapy-specific items before starting the radiotherapy, at the onset of radiotherapy, in the third week of radiotherapy and 3 weeks after the end of radiotherapy. Results: within the first week of treatment the psychological distress of the patients is increasing; 98.8 % of the patients are 'moderate distressed', 46 % 'severe distressed'. General physical symptoms seem not to be affected by the radiotherapy, there is no changing. The distress caused by the organization of the radiotherapy is decreasing, while therapy-related symptoms are increasing in the course of radiotherapy. Even after the end of the therapy these symptoms keep on causing distress, sometimes in a higher amount than before. A correlation between sex, sort of cancer and curative or palliative treatment and the amount of distress was found. Conclusion: the results stress the importance of adequate emotional support for patients undergoing radiotherapy especially in the first week of treatment and after the treatment. There is a need for the development of a valid radiotherapy - questionnaire in order to be able to measure the distress of these patients. (author)

    Full Text Available Anaemia is one of the significant public health problems among children in the world. Understanding risk factors of anaemia provides more insight to the nature and types of policies that can be put up to fight anaemia. We estimated the prevalence and risk factors of anaemia in a population-based, cross-sectional survey.Blood samples from 11,711 children aged between 6 months and 14 years were collected using a single-use, spring-loaded, sterile lancet to make a finger prick. Anaemia was measured based on haemoglobin concentration level. The generalized linear model framework was used to analyse the data, in which the response variable was either a child was anemic or not anemic.The overall prevalence of anaemia among the children in Kenya was estimated to be 28.8%. Across each band of age within which the definition of anaemia remained constant (0–4, 5–11, and 12–14 years old, the prevalence of anaemia declined with each year of age. [corrected]. The risk of anaemia was significantly higher in male than female children. Mothers with secondary and above education had a protective effect on the risk of anaemia on their children. Malaria diagnosis status of a child was positively associated with risk anaemia.Controlling co-morbidity of malaria and improving maternal knowledge are potential options for reducing the burden of anaemia.

    Full Text Available BACKGROUND AND OBJECTIVES: Hookworm infection is among the major causes of anaemia in poor communities, but its importance in causing maternal anaemia is poorly understood, and this has hampered effective lobbying for the inclusion of anthelmintic treatment in maternal health packages. We sought to review existing evidence on the role of hookworm as a risk factor for anaemia among pregnant women. We also estimate the number of hookworm infections in pregnant women in sub-Saharan Africa (SSA. METHODS: Structured searches using MEDLINE and EMBASE as well as manual searches of reference lists were conducted, and unpublished data were obtained by contacting authors. Papers were independently reviewed by two authors, and relevant data were extracted. We compared haemoglobin concentration (Hb according to intensity of hookworm infection and calculated standardised mean differences and 95% confidence intervals. To estimate the number of pregnant women, we used population surfaces and a spatial model of hookworm prevalence. FINDINGS: One hundred and five reports were screened and 19 were eligible for inclusion: 13 cross-sectional studies, 2 randomised controlled trials, 2 non-randomised treatment trials and 2 observational studies. Comparing uninfected women and women lightly (1-1,999 eggs/gram [epg] infected with hookworm, the standardised mean difference (SMD was -0.24 (95% CI: -0.36 to -0.13. The SMD between women heavily (4000+ epg infected and those lightly infected was -0.57 (95% CI: -0.87 to -0.26. All identified intervention studies showed a benefit of deworming for maternal or child health, but since a variety of outcomes measures were employed, quantitative evaluation was not possible. We estimate that 37.7 million women of reproductive age in SSA are infected with hookworm in 2005 and that approximately 6.9 million pregnant women are infected. CONCLUSIONS: Evidence indicates that increasing hookworm infection intensity is associated with

Of 52 cases subjected for electrophoresis 36 were homozygous, 15 were heterozygous and 1 case Sickle thalassemia. 7 cases showed HbF above 5%. Conclusions: Most of the patients were under 40 yrs suggesting decreased survival after that age. An increased level of HbF was associated with better prognosis suggesting the need to target at drugs which increase HbF. [Int J Res Med Sci 2016; 4(1.000: 246-251

  18. Ineffective erythropoiesis and regulation of iron status in iron loading anaemias.

    Science.gov (United States)

    Camaschella, Clara; Nai, Antonella

    2016-02-01

    The definition 'iron loading anaemias' encompasses a group of inherited and acquired anaemias characterized by ineffective erythropoiesis, low hepcidin levels, excessive iron absorption and secondary iron overload. Non-transfusion-dependent β-thalassaemia is the paradigmatic example of these conditions that include dyserythropoietic and sideroblastic anaemias and some forms of myelodysplasia. Interrupting the vicious cycle between ineffective erythropoiesis and iron overload may be of therapeutic benefit in all these diseases. Induction of iron restriction by means of transferrin infusions, minihepcidins or manipulation of the hepcidin pathway prevents iron overload, redistributes iron from parenchymal cells to macrophage stores and partially controls anaemia in β-thalassaemic mice. Inhibition of ineffective erythropoiesis by activin ligand traps improves anaemia and iron overload in the same models. Targeting iron loading or ineffective erythropoiesis shows promise in preclinical studies; activin ligand traps are in clinical trials with promising results and may be useful in patients with ineffective erythropoiesis.

    All viruses infecting fish must cross the surface mucosal barrier to successfully enter a host. Infectious salmon anaemia virus (ISAV), the causative agent of the economically important infectious salmon anaemia (ISA) in Atlantic salmon, Salmo salar L., has been shown to use the gills as its entry point. However, other entry ports have not been investigated despite the expression of virus receptors on the surface of epithelial cells in the skin, the gastrointestinal (GI) tract and the conjunctiva. Here we investigate the ISAV mucosal infection in Atlantic salmon after experimental immersion (bath) challenge and in farmed fish collected from a confirmed outbreak of ISA in Norway. We show for the first time evidence of early replication in several mucosal surfaces in addition to the gills, including the pectoral fin, skin and GI tract suggesting several potential entry points for the virus. Initially, the infection is localized and primarily infecting epithelial cells, however at later stages it becomes systemic, infecting the endothelial cells lining the circulatory system. Viruses of low and high virulence used in the challenge revealed possible variation in virus progression during infection at the mucosal surfaces. PMID:26490835

    Purpose: Tumor hypoxia is correlated with treatment failure. To date, there are no published studies investigating hypoxia in non-small cell lung cancer (NSCLC) patients undergoing SBRT. We aim to use 18F-fluoromisonidazole (18F-FMISO) positron emission tomography (PET) imaging to non-invasively quantify the tumor hypoxic volume (HV), to elucidate potential roles of reoxygenation and tumor vascular response at high doses, and to identify an optimal prognostic imaging time-point. Methods: SBRT-eligible patients with NSCLC tumors >1cm were prospectively enrolled in an IRB-approved study. Computed Tomography and dynamic PET images (0–120min, 150–180min, and 210–240min post-injection) were acquired using a Siemens BiographmCT PET/CT scanner. 18F-FMISO PET was performed on a single patient at 3 different time points around a single SBRT delivery of 18 Gy and HVs were compared using a tumor-to-blood ratio (TBR)>1.2 and rate of influx (Ki)>0.0015 (Patlak). Results: Results from our first patient showed substantial temporal changes in HV following SBRT. Using a TBR threshold >1.2 and summed images 210–240min, the HVs were 19%, 31% and 13% of total tumor volume on day 0, 2 (48 hours post-SBRT), and 4 (96 hours post-SBRT). The absolute volume of hypoxia increased by nearly a factor of 2 after 18 Gy and then decreased almost to baseline 96 hours later. Selected imaging timepoints resulted in temporal changes in HV quantification obtained with TBR. Ki, calculated using 4-hour dynamic data, evaluated HVs as 22%, 75% and 21%, respectively. Conclusions: ith the results of only one patient, this novel pilot study highlights the potential benefit of 18F-FMISO PET imaging as results indicate substantial temporal changes in tumor HV post-SBRT. Analysis suggests that TBR is not a robust parameter for accurate HV quantification and heavily influenced by imaging timepoint selection. Kinetic modeling parameters are more sensitive and may aid in future treatment individualization

    Full Text Available Anaemia is a major public health problem that has affected around 25% of the world’s population. An analytical cross-sectional study was performed on 313 female undergraduates residing in hostels of University of Sri Jayewardenepura, Sri Lanka, during year 2011. Objective of this study was to determine prevalence and contributing factors to anaemia among the study population. Haemoglobin concentration was assayed using cyanomethaemoglobin method. A pretested self-administered questionnaire was used to retrieve information regarding dietary habits and personal factors of participants. Descriptive statistical methods, chi-square test, and independent sample t-test were used to analyze data. Of the 302 females, 17.5% (n=53 had mild anaemia and 7.9% (n=24 had moderate anaemia. Severely anaemic individuals were not observed. Participants’ dietary habits and personal factors were not significantly associated with prevalence of anaemia (whether a participant is a vegetarian or not (P=0.525, drinking tea within one hour of a meal (P=0.775, frequency of consumption of red meat, fish, and eggs (P=0.499, antihelminthic treatment within past year (P=0.792, and menorrhagia (P=0.560. Anaemia in the study population is below the average for Sri Lankan data. Diet and selected medical conditions were not a causative factor for anaemia in this population.

  4. Palliative Radiotherapy

    Palliative care does not attempt to prolong survival but to the achieve the highest quality of life both for the patient and their family covering their physical, psychological, social and spiritual needs. Radiotherapy (RT), one of the most important therapeutic modalities, has a great significance in palliative medicine for cancer since it attempts to reduce as much as possible the acute reaction associated with the treatment for the patient.

    2014-12-01

    Full Text Available Background: About one-third of the global population is anaemic. WHO has estimated that prevalence of anaemia in pregnant women is 18% in developed countries and relatively high 56% in developing countries. Prevalence of anaemia in South East Asian countries is highest in the world. WHO estimates that even among the South East Asian countries, India has the highest prevalence of anaemia. Aims & Objectives: To determine the prevalence of anaemia among pregnant women and to determine association of anaemia with its socio-demographic factors. Material & Methods: A descriptive cross sectional study was conducted among pregnant women 2nd trimester onwards who came to ante natal clinic of obstetrics and gynaecology department during January-March 2014 by using pre-designed, pretested schedule. A total of 300 pregnant women were clinically examined. Written consent was taken. Haemoglobin estimation was done by Cyanmethaemoglobin method and anaemia was graded according to WHO criteria. Statistical analysis was done using Microsoft Excel 2007 and SPSS Version 17. Results: Overall prevalence of anaemia among the pregnant women was found to be 58.3%. It was seen that 31% of women were illiterate and 38.7% of them belong to upper middle class. Factors such as level of education of women, occupation and consumption of Iron Folic Acid were found to be significantly associated with prevalence of anaemia in pregnancy. Conclusion: A very high prevalence of anaemia in pregnancy needs awareness about late marriage, birth spacing, one or two child norm, antenatal care, green leafy vegetable in diet, mandatory regular supply of IFA tablets to adolescent and pregnant women along with correction of other nutritional deficiencies.

    A 64-year-old farmer developed aplastic anaemia after exposure to 2-methyl-4-chlorphenoxyactic acid while spraying weed killer. Muscular weakness, haemorrhagic gastritis and slight signs of liver damage occurred at the same time. All these symptoms, including blood dyscrasia , are consistent with those described as toxic effects of chlorphenoxyacetic acids in animal experiments. A causal relationship between aplastic anaemia and the 2-methyl-4-chlorphenoxyacetic acid thus seems probable. The anaemia was reversible, but the case serves as a warning that careful safety measures are required during the use of chlorphenoxyacetic acids and related compounds. PMID:804793

    Full Text Available Anaemia is a relatively common finding in HIV-positive patients, with rates (among females as high as 37%, compared with their HIV negative counterparts (17%. Anaemia of chronic disease plays a very important role in this population group, and is estimated to occur in 18 - 95% of cases. For this reason, it is imperative to distinguish this condition from other underlying or concurrent causes of anaemia that may warrant treatment. This clinical case illustrates the value of critically evaluating the parameters of a full blood count and haematinic screen, to so determine which patients warrant further workup.

    Computed tomography of the upper abdomen and of the heart was performed in 21 patients with severe anaemia (mean haematocrit value 0.23, mean haemoglobin content 39.6%). Gross morphology of the heart and great vessels (wall thickness, size of the chambers, lumina and walls of the vessels) were visualized in all patients without the use of contrast media. The smallest discernible difference between the normal heart muscle and blood filling its cavities was about 6-8 H and the smallest discernible difference between the aorta and the aortic blood was about 8-10 H (window width 150 H, window level 50 H). There were no CT signs of haemochromatosis of the heart, while CT measurements were highly suggestive of liver haemochromatosis in several cases. Visual evaluation of liver density in comparison to the density of blood in hepatic and portal vessels is misleading.

  9. Acute lymphoblastic leukemia in a child with fanconi's anaemia

    International Nuclear Information System (INIS)

    Fanconi anaemia (FA) is an autosomal recessive inherited disorder with progressive bone marrow failure, associated congenital malformation and solid and haematological malignancies. Acute myeloid leukemia is the commonest haematological malignancy followed by myelodysplastic syndrome in children with FA. FA transformed into acute lymphoblastic leukemia (ALL) is a rare phenomenon and one of the rarest haematological malignancies associated with this disorder. We are reporting a 13 years old girl with FA and positive chromosomal breakage. She required regular blood product transfusion. She was planned for haematopoietic stem cell transplantation (HSCT) but the sibling-matched donor was found to have chromosomal breaks as well. Later on, her peripheral smear showed blast cell. Bone marrow showed pre-B ALL. She was started on chemotherapy but died shortly due to complications of the treatment. For this rare condition conservative management is indeed essential, however, safe and appropriate chemotherapy regimen is needed. (author)

    S2 is an accessory protein of equine infectious anaemia virus (EIAV), the function of which is unknown. In order to gain insight into the function of S2, the intracellular localization of the protein, its interaction with viral proteins and its incorporation into viral particles have been investigated. Immunolocalization of S2 revealed punctate staining in the cytoplasm and the S2 protein co-precipitated with the EIAV Gag precursor. Despite overexpression of S2 through the use of a codon-optimized sequence, there was no preferential association of S2 with EIAV particles. These data suggest that S2 may function to organize the Gag protein during particle assembly in the cytoplasm but that it is unlikely to be involved in the early stages of the virus life-cycle.

    Objective:To assess the role of oxidative stress on anaemia in pregnancy.Methods:Blood samples were collected from pregnant and non-pregnant women who came for antenatal clinic and medical check at Comprehensive Health Center, Akungba-Akoko and Iwaro General Hospital in Akoko Area of Ondo State, Nigeria. Thick and thin blood films were prepared and used for malaria parasite counts. Haemoglobin level was determined by colorimetric method using Drabkin's solution. Oxidative status was determined using malondiadelhyde level as an indicator of lipid peroxidation, while ascorbic acid and reduced glutathione levels were measured by standard spectrophotometric methods.Results: Mean parasite density was significantly higher in pregnant women than non-pregnant women (P<0.05). Haemoglobin level was significantly reduced in malaria positive pregnant and non-pregnant women than malaria negative (8.3-10.0 g/dL) (P<0.05). The oxidative status indicated that malondialdehyde(MDA) was significantly increased in pregnant [(2.5±0.7) nmol/mL] than non-pregnant women [(1.8±0.1) nmol/mL] (P<0.05), while Vit C and superoxide dismutase(SOD) levels were significantly reduced in pregnant than non-pregnant women(P<0.05). There was an inverse correlation between Hb and MDA levels in pregnant women studied. Positive correlation was observed between the mean MDA level and parasite density (r = 0.53). The Hb level decreased as the parasite density and MDA level increased in pregnant women.Conclusions:This study shows that oxidative stress, caused by malaria infection could be part of the contributing factors responsible for anaemia in pregnancy.

    Since there have been few reports on postmastectomy radiotherapy having a high evidence level in Japan, the significance of postoperative radiotherapy and the irradiation techniques were reviewed based on reports from Western countries. Authors focused on the indications for postoperative irradiation, irradiation methods (irradiation sites, irradiation techniques; prosthetics, methods of irradiating the chest wall and lymph nodes, timing of irradiation), and complications, and discuss them. The factors thought to be adaptable to postmastectomy radiotherapy have been listed. Axillary lymph node metastasis and the size of the primary focus are thought to be important factors in locoregional recurrence. The chest wall and the supraclavicular lymph nodes are the usual sites of irradiation after mastectomy. The irradiation method consists of tangential irradiation of the chest wall and single-field irradiation of the supraclavicular lymph nodes, with 46-50 Gy in fractional doses of 1.8-2 Gy x 5/w is administered for 4.5-5.5 weeks. The timing of irradiation in the West is generally after chemotherapy. Adverse radiation effects include ischemic heart disease, pneumonitis, arm edema, rib fractures, and brachial plexus paralysis. The frequency of these complications is increased by the combined use of chemotherapy or surgery. The breast cancer cure rate in Japan is generally better than in the West. It remains to be determined whether the clinical data from Europe and America are applicable to the treatment of breast cancer in Japan. To address this issue, a clinical investigation should be performed in Japan with close cooperation between surgeons, physicians, pathologists, and radiotherapists. (K.H.)

  13. The role of anaemia in the effectivity of radiation treatment of cancer of the collum uteri

    International Nuclear Information System (INIS)

    The role of anaemia is studied in 129 patients with cancer of the collum uteri subjected to combined radiation treatment by comparing data on anaemia and five years survival rates. Since prognosis as well as incidence of anaemia depend on the extend of the disorder the comparison is done for each clinical stage separately. Only in patients found in clinical III b statistical verification (p<0.001) is present witnessing that survival of anaemia patients is shorter than in the rest of the patients. Factors contributing to these differences being discussed a conclusion is drawn that it may be due to a lowered effectivity of the radiation treatment induced by the existing hypoxy. With this regard the relationship is discussed between oxygen tissue diffusion, cellular proliferation of tumors and the effect of ionizing radiation. (author)

  16. Warm Autoimmune Haemolytic Anaemia and autoimmune hepatitis in an asymptomatic carrier of hepatitis B virus

    International Nuclear Information System (INIS)

    Warm antibody autoimmune haemolytic anaemia, a rare disease (0.2-1 per 100,000 populations), is due to the presence of warm agglutinins that react with protein antigens on the surface of red blood cells causing their premature destruction. Here, we present a case report of a 10 year old girl who came with features of haemolytic anaemia and history of blood transfusion since 3 years. On admission, laboratory test revealed that she had autoimmune hepatitis type 1 and was also an asymptomatic carrier of hepatitis B virus with positive HBs Ag. Steroid therapy resulted in clinical and laboratory remission. Direct antiglobulin test was negative after anaemia resolution, hepatitis B virus antigenemia persisted. To our knowledge, warm antibody autoimmune hemolytic anaemia has not previously been described in association with autoimmune hepatitis and asymptomatic carrier state of hepatitis B virus. (author)

  17. Intraoperative radiotherapy

    International Nuclear Information System (INIS)

    The potential benefit of intraoperative radiotherapy (IORT) was originally recognized years ago and has recently attracted renewed interest. Modern radiotherapeutic approaches may be more successful as a result of technical innovation, particularly in the use of electron beam accelerators. Preliminary studies, mainly uncontrolled and nonrandomized, have assessed the role of IORT for treatment of a variety of deep seated abdominal, retroperitoneal, and pelvic cancers. The results of some studies show much promise, but prospective trials are needed to scientifically validate these favorable initial observations. (Auth.)

    Early stage glottic carcinoma can be treated with primary radiotherapy reaching equally good results compared to primary surgery; for supraglottic carcinoma surgery offers only slight advantages over primary radiotherapy. Tumor control for recurrences is considerably improved by salvage surgery. The use of primary radiotherapy allows improved or at least preserved voice and reduced rated of acute complications and late treatment sequelae. However, treatment duration is longer and probably more expensive compared to function preservation microlaryngoscopic surgery. Which treatment approach is chosen, depends in individual patient factors and specific conditions in the clinical setting. In any case, primary radiotherapy deserves a stronger say in the early stage tumor situation. In our institution early stage supraglottic carcinoma undergo primary surgery. Advanced carcinomas (T2b and more) are rarely suited for primary radiotherapy with the exception of some very confined T3 tumors. Surgical approaches should be favoured, since they provide a detailed pathological tumor staging including R-classification, which would be lacking using primary radiotherapy. There are clear reasons to treat the lymph nodes for glottic carcinomas stage T2b and more and for all supraglottic carcinomas with radiotherapy. Specific risk factors are: tumor at the margins of the incision (R1), infiltration of the cartilage and pre-epiglottic space, paratracheal and subglottic extension more than 1 cm, perineural invasion, grade III and IV as well as emergency tracheostomy. Postoperative radiotherapy should be given to the lymph nodes for all positive neck-dissections. New therapeutic approaches are on the horizon, which may improve thee results of radiotherapy even for advanced larynx carcinomas, like hyperfractionation radiotherapy and simultaneous radio-chemotherapy combined enoral resection and postoperative radiotherapy may yield larynx preservation even for advanced stages.

    Full Text Available ABSTRACT: BACKGROUND: More than one - third of world’s women are a naemic with majority residing in developing countries and that too in rural areas. The most highly affected population in the decreasing order is pregnant women, school age children, non - pregnant women and preschool children. Nutritional anaemia has recent ly been ranked as the third leading problem among the women of reproductive age group. Most of the studies conducted so far have focused on pregnant ladies only so it was decided to take all the females in the reproductive age group as the study subjects. AIMS: To find out the prevalence of nutritional anaemia among married females of reproductive age group i.e., 15 - 49 years of age in a rural area of Jammu District. SETTINGS AND DESIGN : Across - sectional study was undertaken in rural settings. METHODS AND M ATERIAL: House to house visits were made and288married females in the reproductive age group were interviewed and their blood samples were taken for necessary haematological investigations which were done at GMC Jammu. STATISTICAL ANALYSIS : Percentages an d chi - square test . RESULTS AND CONCLUSION : More than 90% of the females were suffering from anaemia. Majority of them were having microcytic hypochromic blood picture. More than 50% of the subjects were having moderate anaemia as per WHO classification. Nu tritional anaemia was seen in 70.47% of the study subjects while the remaining females were having either no anaemia or anaemia due to other medical reasons. The prevalence of nutritional anaemia was even more among pregnant and lactating females and this finding was found to be statistically significant.

  3. Influence of Schistosoma mansoni and Hookworm Infection Intensities on Anaemia in Ugandan Villages.

    Full Text Available The association of anaemia with intestinal schistosomiasis and hookworm infections are poorly explored in populations that are not limited to children or pregnant women.We sampled 1,832 individuals aged 5-90 years from 30 communities in Mayuge District, Uganda. Demographic, village, and parasitological data were collected. Infection risk factors were compared in ordinal logistic regressions. Anaemia and infection intensities were analyzed in multilevel models, and population attributable fractions were estimated.Household and village-level predictors of Schistosoma mansoni and hookworm were opposite in direction or significant for single infections. S. mansoni was found primarily in children, whereas hookworm was prevalent amongst the elderly. Anaemia was more prevalent in individuals with S. mansoni and increased by 2.86 fold (p-value<0.001 with heavy S. mansoni infection intensity. Individuals with heavy hookworm were 1.65 times (p-value = 0.008 more likely to have anaemia than uninfected participants. Amongst individuals with heavy S. mansoni infection intensity, 32.0% (p-value<0.001 of anaemia could be attributed to S. mansoni. For people with heavy hookworm infections, 23.7% (p-value = 0.002 of anaemia could be attributed to hookworm. A greater fraction of anaemia (24.9%, p-value = 0.002 was attributable to heavy hookworm infections in adults (excluding pregnant women as opposed to heavy hookworm infections in school-aged children and pregnant women (20.2%, p-value = 0.001.Community-based surveys captured anaemia in children and adults affected by S. mansoni and hookworm infections. For areas endemic with schistosomiasis or hookworm infections, WHO guidelines should include adults for treatment in helminth control programmes.

    Full Text Available Introduction: Anaemia continues to be a major public health nutritional problem in India, and has adverse health and economic implications. Objective: The objective of the study was to assess the prevalence of anaemia among different physiological groups in the state of Maharashtra. Methodology: A community based cross-sectional study adopting multistage stratified random sampling procedure was carried out in rural Maharashtra. Information of socio-demographic particulars was collected with pretested questionnaire. A finger prick blood sample of 20 µL was collected from the subjects. Haemoglobin was estimated using cyanmethemoglobin method. Results: The overall prevalence of anaemia was 59%, 61%, 76% and 73% among pre-school children, adolescent girls, pregnant women and lactating mothers, respectively. Logistic regression analysis revealed that the risk of anaemia was two times higher among pregnant and lactating women and among the subjects belonged to scheduled caste and scheduled tribe communities. Conclusion: Anaemia is a severe public health problem among pre-school children and women of different physiological groups in rural Maharashtra. Therefore, there is a need to strengthen the existing national nutritional anaemia control programme and the community is encouraged to consume iron rich foods through health and nutrition education and information, education and communication (IEC activities.

  12. Hormone levels in radiotherapy treatment related fatigue

    International Nuclear Information System (INIS)

    Radiotherapy is known to cause debilitating treatment related fatigue. Fatigue in general is a conglomeration of psychological, physical, hematological and unknown factors influencing the internal milieu of the cancer patient. Radiotherapy can add stress at the cellular and somatic level to aggravate further fatigue in cancer patients undergoing radiotherapy. Stress related hormones might be mediating in the development of fatigue. This is an ongoing prospective study to evaluate if the hormonal profile related to stress is influenced by radiotherapy treatment related fatigue. The study was conducted from September 2002 onwards in the division of Radiotherapy and Oncology of our Medical School. Previously untreated patients with histopathology proof of malignancy requiring external beam radiotherapy were considered for this study. Selection criteria were applied to exclude other causes of fatigue. Initial fatigue score was obtained using Pipers Fatigue Score questionnaire containing 23 questions, subsequently final fatigue score was obtained at the end of radiotherapy. Blood samples were obtained to estimate the levels of ACTH, TSH, HGH, and cortisol on the final assessment. The hormone levels were compared with resultant post radiotherapy fatigue score. At the time of reporting 50 patients were evaluable for the study. The total significant fatigue score was observed among 12 (24%) patients. The individual debilitating fatigue score were behavioral severity 14 (28%), affective meaning 14(28%), Sensory 13 (26%) and cognitive mood 10 (20%) respectively. From the analysis of hormonal profile, growth hormone level > 1 ng/mL and TSH <0.03 appears to be associated with high fatigue score (though statistically not significant); whereas there was no correlation with ACTH and serum cortisol level. In our prospective study severe radiotherapy treatment related fatigue was found among our patient population. Low levels of TSH and high levels of GH appear to be associated

  13. Effect of severe anaemia on renal function: a case-control study

    International Nuclear Information System (INIS)

    Aim: Anaemia, if severe, causes multi systemic functional changes. We tried to find out the effect of severe anaemia on renal function. Materials and Methods: A total of 66 patients with severe anemia and 10 healthy controls were recruited in this study. The cases were divided into following groups: group A: patients with Hb≤3 gm/dl (n=33); group B: patients with Hb≤6 but > 3 gm/dl (n=33); group C: healthy controls with normal renal function and Hb>12gm/dl. Out of 66 anaemic patients, 36 had nutritional anaemia (mainly iron deficiency; group A=20, group B=16), 24 patients were suffering from aplastic anaemia (group A=11, group B=13) and rest 6 had megaloblastic anaemia (group A=2, group B=4). No subject had hypertension, diabetes, primary renal dysfunction or any other systemic illness, affecting kidney. Various renal function test parameters and diagnostic renal failure indices were obtained for all subjects. GFR with 2-sample method after injection of 99m-Tc DTPA and ERPF with single sample method after injection of 131-I OIH were also calculated. Results: Fourteen patients had mild to moderate pedal edema (10 in group A and 4 in group B). Out of these patients, 8 had palpable liver and signs of systemic congestion. Signs of raised systemic venous pressure (raised JVP) were found in 7 patients of group A. In about 55% of patients, chest x-ray showed mild to moderately enlarged heart with disturbed cardiophrenic angle. Urine output was >600 ml/day in all cases. Results are presented. All renal functional parameters and indices were significantly reduced in anaemic patients and were suggestive of pre-renal failure. The reduction was correlating well with the severity of anaemia.Conclusion: Severe anaemia leads to renal dysfunction with alteration of minor and major renal failure indices, which can be characterized by sub-clinical and pre-biochemical non-oliguric pre-renal failure

  14. Iron deficiency anaemia -a risk factor for febrile seizures in children

    International Nuclear Information System (INIS)

    Background: Iron deficiency anaemia and febrile seizures are two common diseases in children worldwide as well as in our country. Iron insufficiency is known to cause neurological symptoms like behavioural changes, poor attention span and learning deficits in children. Therefore, it may also be associated with other neurological disturbances like febrile seizures in children. Objective of our case-control study was to find association between iron deficiency anaemia and febrile seizures in children. Methods: This multicentre study was conducted in Department of Paediatrics HIT Hospital Taxila Cantt, Department of Paediatrics CMH Mangla and Department of Paediatrics POF Hospital Wah Cantt, from June 2008 to June 2010. Three hundred and ten children aged between 6 months to 6 years were included in the study. One hundred and fifty-seven children who presented with febrile seizures were our cases, while, 153 children who presented with febrile illnesses without seizures were recruited as controls. All patients were assessed for iron deficiency anaemia by measuring haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration (MCHC) and Mean Corpuscular Volume (MCV). Patients with iron deficiency anaemia amongst controls and cases were documented. Percentages and Odds ratio were derived from the collected data. Results: 31.85% of cases (50 out of 157) had iron deficiency anaemia whereas, 19.6% of controls (30 out of 153) were found to have iron deficiency anaemia as revealed by low levels of haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration and Mean Corpuscular Volume. Odds ratio was 1.93. Conclusion: Patients with febrile seizures are 1.93 times more likely to have iron deficiency anaemia compared to febrile patients without seizures. (author)

  15. Prevention of gamma radiation induced anaemia in mice by diltiazem

    International Nuclear Information System (INIS)

    Intraperitoneal administration of diltiazem (DTZ), half an hour prior to whole body gamma irradiation (2.5, 5.0, and 7.5 Gy), showed the protection of animals from radiation-induced anaemia. Radiation exposure significantly (p<0.001) reduced the number of pro- and normoblasts in bone marrow and red blood cell (RBC) counts, hemoglobin (Hb), hematocrit (Hct), and erythropoietin (EPO) level in blood, but increased myeloid/erythroid ratio. At all the radiation doses, the maximum decrease in these values was noted on the 3rd day, followed by a gradual recovery from the 7th day, but it was not recorded as normal even until the end of experimentation. In animals pretreated with DTZ, these values were measured higher at all the time periods in comparison to corresponding control, and these were almost normal at the last autopsy interval only at 2.5 Gy radiation dose. DTZ maintained the higher EPO level in blood, which acted on bone marrow and spleen colony forming unit for erythroblast (CFU-E), and stimulated such cells to produce RBCs. These results confirm that DTZ has the potency to alter anaemic condition favorably through the protection of bone marrow stem cells, and subsequently it maintains the higher number of pro-and normoblasts in bone marrow, RBC counts, Hb, Hct percentage, and EPO level in blood and the lower myeloid/erythroid ratio in bone marrow.

    For early-stage lung cancer, the treatment of choice is surgery. In patients who are not surgical candidates or are unwilling to undergo surgery, radiotherapy is the principal treatment option. Here, we review stereotactic body radiotherapy, a technique that has produced quite promising results in such patients and should be the treatment of choice, if available. We also present the major indications, technical aspects, results, and special situations related to the technique. (author)

    International Nuclear Information System (INIS)

    A retrospective study was done to ascertain the risks of cochlear damage from radiotherapy of the nasopharynx. Audiometric evaluation, pre- and post-radiotherapy, revealed that 7 out of 13 patients had sustained sensori-neural deafness. Contrary to what is generally believed of the resistance of the cochlea to radiotherapeutic damage, eventual loss of hearing can occasionally be expected in patients undergoing radiation therapy for head and neck tumors

    2014-09-01

    Full Text Available BACKGROUND: Adolescence is the formative period of life when the maximum amount of physical, psychological and behavioral changes takes place and this is a vulnerable period in the human life cycle for the development of nutritional anaemia, which has been constantly neglected by public health programs. The prevalence of anaemia is disproportionately high in developing countries than developed countries. It has mainly been ascribed to poverty, inadequate diet, certain diseases, pregnancy and lactation, and poor access to health services in developing countries Prevalence of anaemia in adolescents in India have been reported in limited studies available from 16.25% to 96.5%. Nutritional anaemia constitutes the most important cause of anaemia in adolescents. It is mainly due to deficiency of Iron, Vitamin B12 and Folate. Megaloblastic Anaemia resulting from deficiency of folate and B12 appears to be increasing over the last two decades. AIMS AND OBJECTIVES: 1.To study the types of nutritional anemia in adolescents (10-18 yrs. attending the hospital and correlate severity of nutritional anemia with serum levels of ferritin, Vit B12 & folate. 2. And also to determine demographic, socio-economic & nutritional factors for nutritional anemia in adolescents. STUDY DESIGN: A cross sectional study was conducted in selected sample of 200 subjects. SETTINGS: The study was conducted in the Department of General Medicine, Azeezia Medical College; during November 2011 to April 2013, as a cross-sectional observational study. MATERIALS AND METHODS: Subjects were selected based on the inclusion criteria set and evaluated with aid of laboratory investigation of blood samples collected from subjects. RESULTS AND CONCLUSION: Present study was undertaken to find out etiology and socio-demographic correlates of nutritional anaemia in adolescents. And it was found out that Folate deficiency was the most common followed by Vitamin B12 deficiency & then irons deficiency

    Full Text Available Aim. We determined the prevalence of anaemia and evaluated markers of iron homeostasis in a cohort of HIV patients. Methods. A comparative cross-sectional study on 319 participants was carried out at the Tamale Teaching Hospital from July 2013 to December 2013, 219 patients on HAART (designated On-HAART and 100 HAART-naive patients. Data gathered include sociodemography, clinical history, and selected laboratory assays. Results. Prevalence of anaemia was 23.8%. On-HAART participants had higher CD4/CD3 lymphocyte counts, Hb, HCT/PCV, MCV, MCH, iron, ferritin, and TSAT (P<0.05. Hb, iron, ferritin, and TSAT decreased from grade 1 to grade 3 anaemia and CD4/CD3 lymphocyte count was lowest in grade 3 anaemia (P<0.05. Iron (P=0.0072 decreased with disease severity whilst transferrin (P=0.0143 and TIBC (P=0.0143 increased with disease severity. Seventy-six (23.8% participants fulfilled the criteria for anaemia, 86 (26.9% for iron deficiency, 41 (12.8% for iron deficiency anaemia, and 17 (5.3% for iron overload. The frequency of anaemia was higher amongst participants not on HAART (OR 2.6 for grade 1 anaemia; OR 3.0 for grade 3 anaemia. Conclusion. In this study population, HIV-associated anaemia is common and is related to HAART status and disease progression. HIV itself is the most important cause of anaemia and treatment of HIV should be a priority compared to iron supplementation.

    Full Text Available Anaemia is known to have an impact on child development and mortality and is a severe public health problem in most countries in sub-Saharan Africa. We investigated the consistency between ecological and individual-level approaches to anaemia mapping by building spatial anaemia models for children aged ≤15 years using different modelling approaches. We aimed to (i quantify the role of malnutrition, malaria, Schistosoma haematobium and soil-transmitted helminths (STHs in anaemia endemicity; and (ii develop a high resolution predictive risk map of anaemia for the municipality of Dande in northern Angola. We used parasitological survey data for children aged ≤15 years to build Bayesian geostatistical models of malaria (PfPR≤15, S. haematobium, Ascaris lumbricoides and Trichuris trichiura and predict small-scale spatial variations in these infections. Malnutrition, PfPR≤15, and S. haematobium infections were significantly associated with anaemia risk. An estimated 12.5%, 15.6% and 9.8% of anaemia cases could be averted by treating malnutrition, malaria and S. haematobium, respectively. Spatial clusters of high risk of anaemia (>86% were identified. Using an individual-level approach to anaemia mapping at a small spatial scale, we found that anaemia in children aged ≤15 years is highly heterogeneous and that malnutrition and parasitic infections are important contributors to the spatial variation in anaemia risk. The results presented in this study can help inform the integration of the current provincial malaria control programme with ancillary micronutrient supplementation and control of neglected tropical diseases such as urogenital schistosomiasis and STH infections.

  2. Frequency of anaemia an d renal insufficiency in patients with heart failure

    International Nuclear Information System (INIS)

    Background: Heart Failure (HF) is a common disease with a high mortality rate. Anaemia and renal failure (RF) are often present in patients with HF and associated with worse prognosis. Objective of study was to evaluate the prevalence of anaemia and RF in patients with HF. Methods: Patients admitted in Punjab institute of cardiology Lahore with diagnosis of heart failure were enrolled from February, 2008 to December, 2008. Anaemia was defined as haemoglobin levels <13 mg/dl for men and 12 mg/dl for women. Renal function was assessed by the glomerular filtration rate (GFR), calculated by the simplified formula of the MDRD (Modification of Diet in Renal Disease) study. Results : Of the 276 patients included in this study, 42.03% (116) had anaemia and 38.40% (106) had moderate to severe renal failure (GFR <60 ml/min). Conclusion: The prevalence of anaemia and renal failure was high in this population and was associated with the severity of the HF (functional classes III and IV). (author)

    2014-01-01

    Full Text Available Background: Sickle cell haemoglobin (HbS is the commonest abnormal haemoglobin and it has a worldwide distribution. Reports have shown that patients with sickle cell anaemia (HbSS have an increased susceptibility to infection leading to increased morbidity and mortality. Impaired leucocyte function and loss of both humoral and cell-mediated immunity are some of the mechanisms that have been reported to account for the immunocompromised state in patients with sickle cell disease. This study was carried out to determine the CD4+ T lymphocytes count in patients with sickle cell anaemia. Materials and Methods: A comparative cross-sectional study of 40 sickle cell anaemia patients in steady state (asymptomatic for at least 4 weeks attending haematology clinic and 40 age and sex-matched healthy HbA control were recruited into the study. Both HbS patients and the controls were HIV negative. The blood samples obtained were analyzed for CD4+ T cell by Flow cytometry. Results: The study found that there was no significant difference in the number of CD4+ T lymphocyte count between individuals with sickle cell anaemia and HbA (1016 ± 513 cells/μL vs 920 ± 364cells/μL. Conclusion: It is recommended that the functionality of CD4+ T lymphocyte should be considered rather than the number in further attempt to elucidate the cellular immune dysfunction in patients with sickle cell anaemia.

  4. Incidence of nutritional anaemia among the under five children attending Ahmed Gasim hospital

    International Nuclear Information System (INIS)

    A survey was carried out in Khartoum North Ahmed Gasim specialist Hospital for children to identify aetiological factors that lead to incidence of nutritional anaemia among children under under five years of age. The sample consists of 192 patients taken from the hospital wards (experimental group), and 60 healthy children taken from out patient vaccination department of same hospital. A questionnaire was used as a tool for collection data regarding children and their families with emphasis to general information, socio-economic information, dietary information, anthropometric information, medical history and laboratory investigations including haemoglobin, hematocrit (PCV)%, peripheral blood picture, serum ferritin, serum folate and serum B12. Results show no correlation between anaemia and age R(0.1048) p12 deficiency. Some children affected had mixed deficiency anaemia (3.182). Iron deficiency without anaemia was common among healthy children (control) 22.8%. Some recommendations were set for the improvement of the existing situation e.g. health education, nutrition education with emphasis on intake of supplements and weaning diets rich in iron and folate. Follow up and surveillance program to compact nutritional anaemia should be adopted.(Author)

    International Nuclear Information System (INIS)

    An anthropological study has been carried out in order to evaluate the need expressed by patients undergoing radiotherapy treatment. The study was mostly qualitative and based on the radiotherapy experiences of 13 women with breast cancer and six men with head and neck cancer. A 24-year-old female anthropologist spent one year in the department of radiotherapy at the Bergonie Institute in Bordeaux. She collected data on patients' needs through the observation of their experience of treatment and personal interviews. These were put in context, analyzed both by qualitative and quantitative methods. The results pointed out the need for more information on the different steps of treatment and the patient's need 'for a smile'front the medical team; in other words, emphatic support. (author)

  6. Quality control guarantees the safety of radiotherapy

    International Nuclear Information System (INIS)

    While radiotherapy equipment has seen some decisive improvements in the last few decades, the technology has also become more complicated. The advanced equipment produces increasingly good treatment results, but the condition of the equipment must be controlled efficiently so as to eliminate any defects that might jeopardise patient safety. The quality assurance measures that are taken to show that certain equipment functions as required are known as quality control. The advanced equipment and stricter requirements set for the precision of radiotherapy have meant that more attention must be paid to quality control. The present radiation legislation stipulates that radiotherapy equipment must undergo regular quality control. The implementation of the quality control is supervised by the Finnish Centre for Radiation and Nuclear Safety (STUK). Hospitals carry out quality control in accordance with a programme approved by STUK, and STUK inspectors periodically visit hospitals to check the results of quality control. (orig.)

  7. Radiotherapy: what are the patients' needs

    International Nuclear Information System (INIS)

    Although there is a substantial body of research into the impact of cancer therapies such as surgery and chemotherapy, little is known about the experiences of cancer patients receiving radiotherapy. Serial interviews with 39 patients undergoing radical radiotherapy to the oral cavity revealed that misunderstandings and groundless fears about this form of treatment were widespread. A majority were unprepared for the severity and duration of their side-effects. These results suggest that written information for patients about radiotherapy and its side-effects should be made available routinely. There is also scope for nutritional support. Finally, as a supplement to out-patient attendance, informal contact with the hospital in the immediate post-treatment phase would provide invaluable reassurance to patients. (author)

    Full Text Available CASE REPORT A 63-year old man with refractory anaemia with excess of blasts and a history of heart failure, diabetes and hyperuricaemia, presented with pain, warmth and swelling in the left knee. Blood sample showed white cell blood count 3,840/μL (normal formula, haemoglobin 7.1 g/dL, platelets 117,000/L, eritrosedimentation rate 66 mm/h, normal serum creatinine and uric acid. He had no history of neutropenia, fever or recurrent infections. X-ray of the knee did not show any erosion or lytic lesion. Arthrocentesis produced turbid fluid, with elevated cell count (81,000/μL, mainly polimorphonuclear cells, no urate crystals, normal chemical pattern, sterile culture. Synovial fluid smear showed a huge neutrophilic cellularity with scattered mononuclear cells looking like medullar myeloid blasts. The microscopic examination identified a myeloid infiltration as the cause of arthritis. DISCUSSION AND CONCLUSIONS Rheumatic phenomena in myelodysplastic syndromes have a prevalence of 10% and include vasculitis, neuropaties, glomerulonephritis, lupus-like syndrome, inflammatory bowel disease, lung infiltrates and arthritis. The pathogenesis is usually autoimmune, as in all paraneoplastic syndromes. In our case, arthritis was due to a direct invasion of blasts. This phenomenon is rarely observed in acute leukemias and was not described yet in myelodysplastic syndromes. Synovial fluid analysis is critical to define the ethiology of an articular effusion, microscopical examination is strongly recommended but it is not always carried out. This case shows how simple diagnostic tests can easily disclose rare conditions.

  9. Successful allogeneic stem cells transplantation in severe aplastic anaemia complicated by dengue fever

    International Nuclear Information System (INIS)

    Aplastic anaemia is characterized by severe compromise of haematopoiesis and hypocellular bone marrow. Haemorrhagic episodes in patients with aplastic anemia occur usually secondary to thrombocytopenia and require frequent support with platelet concentrates and other blood products. Infection with dengue virus (particularly dengue sero type-2 of South Asian genotype) is associated with dengue haemorrhagic fever. Dengue infection further worsens the disease process in patients with aplastic anaemia due to uncontrolled haemorrhagic diathesis and major organ failure, which may prove fatal in these already immunocompromised patients, if not treated in time. Recent epidemics of dengue haemorrhagic fever has not only affected the southern region of our country but also spread to other areas of the country. With this background, we report a case of aplastic anaemia complicated by dengue haemorrhagic fever who achieved successful engraftment after allogeneic stem cell transplantation from sibling brother and is having normal healthy post transplant life.

    Erythropoietin regulates erythropoiesis in a hypoxia-inducible manner. Here we generate inherited super-anaemic mice (ISAM) as a mouse model of adult-onset anaemia caused by erythropoietin deficiency. ISAM express erythropoietin in the liver but lack erythropoietin production in the kidney. Around weaning age, when the major erythropoietin-producing organ switches from the liver to the kidney, ISAM develop anaemia due to erythropoietin deficiency, which is curable by administration of recombinant erythropoietin. In ISAM severe chronic anaemia enhances transgenic green fluorescent protein and Cre expression driven by the complete erythropoietin-gene regulatory regions, which facilitates efficient labelling of renal erythropoietin-producing cells. We show that the majority of cortical and outer medullary fibroblasts have the innate potential to produce erythropoietin, and also reveal a new set of erythropoietin target genes. ISAM are a useful tool for the evaluation of erythropoiesis-stimulating agents and to trace the dynamics of erythropoietin-producing cells. PMID:23727690

Megaloblastic anaemia is not uncommon in India , but data are insufficient regarding its prevalence , causative factors and precipitating factors. AIMS & OBJECTIVES : To evaluate the clinic o - haematological profile in patients of macrocytic anaemia. MATERIAL AND METHODS : In the present study , 50 patients of >20years of age with hemoglobin 95 fl and PBF showing macrocytosis and pancytopenia were included. Detailed history with clinical examination was performed and investigations (Bone Marrow aspiration , Serum Folate and cobalamin assays were carried out. RESULTS : The peak incidence of megaloblas tic anaemia was in the age group of 41 - 50 years (48% , with male preponderance (71% . ( The predominant symptoms were fatigue (54% followed by low grade fever (52% , breathlessness (50% , and mild jaundice (22% . ( Physicalfindingswere pallor (88 % , hepatomegaly (80% , knuckle hyperpigmentation (68% , glossitis (50% , peripheral neuropathy (28% and mild icterus was the least common finding in 22% of patients. 64% patients of macrocytic anaemia were found to be lactovegetarian. Cobalamin deficiency wa s present in maximum patients (50% , followed by combined cobalamin and folate deficiency in 34% and folate deficiency in 16% of patients. Bonemarrowsmears revealed megaloblastic picture in 58% of patients and 42% patients had non - megaloblastic bone marrow picture. C ONCLUSION : Megaloblastic anaemia must be considered in the differential diagnosis of patients presenting with pyrexia of unknown origin , mild ic terus or pancytopenia. Therefore , the early screening for cobalamin and folic acid deficiency can lead to improvement in the wellbeing and prolongs the life of people in our community.

    Addressing the complex, multi-factorial causes of childhood anaemia is best done through integrated packages of interventions. We hypothesized that due to reduced child vulnerability, a “buffering” of risk associated with known causes of anaemia would be observed among children living in areas benefiting from a community-based health and nutrition program intervention. Cross-sectional data on the nutrition and health status of children 24–59 mo (N = 2405) were obtained in 2000 and 2004 from p...

Fe2+ ions are converted to Fe3+ ions with a corresponding change in paramagnetic properties that may be quantified using NMR relaxation measurements or optical techniques. Due to predominantly diffusion-related limitations (and references therein), alternative polymer gel dosimeters were subsequently suggested. In polymer gels, monomers such as acrylamide and N,N'-methylene-bis-acrylamide are usually dispersed in a gelatin or agarose matrix. Monomers undergo a polymerisation reaction as a function of absorbed dose resulting in a 3D polymer gel matrix. The radiation-induced formation of polymer influences NMR relaxation properties and results in other physical changes that may be used to quantify absorbed radiation dose. As well as MRI, other quantitative techniques for measuring dose distributions include X-ray computer tomography, vibrational spectroscopy and ultrasound. Clinical applications of these radiologically tissue equivalent gel dosimeters have been reported in the literature. For further information of gel dosimetry and specifically clinical applications the proceedings of the 2nd International Conference on Radiotherapy Gel Dosimetry and references therein should be consulted

  17. 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

  18. Effectiveness of Radiotherapy for Elderly Patients With Glioblastoma

    International Nuclear Information System (INIS)

    Purpose: Radiotherapy plays a central role in the definitive treatment of glioblastoma. However, the optimal management of elderly patients with glioblastoma remains controversial, as the relative benefit in this patient population is unclear. To better understand the role that radiation plays in the treatment of glioblastoma in the elderly, we analyzed factors influencing patient survival using a large population-based registry. Methods and Materials: A total of 2,836 patients more than 70 years of age diagnosed with glioblastoma between 1993 and 2005 were identified from the Surveillance, Epidemiology, and End Results (SEER) registry. Demographic and clinical variables used in the analysis included gender, ethnicity, tumor size, age at diagnosis, surgery, and radiotherapy. Cancer-specific survival and overall survival were evaluated using the Kaplan-Meier method. Univariate and multivariate analysis were performed using Cox regression. Results: Radiotherapy was administered in 64% of these patients, and surgery was performed in 68%. Among 2,836 patients, 46% received surgery and radiotherapy, 22% underwent surgery only, 18% underwent radiotherapy only, and 14% did not undergo either treatment. The median survival for patients who underwent surgery and radiotherapy was 8 months. The median survival for patients who underwent radiotherapy only was 4 months, and for patients who underwent surgery only was 3 months. Those who received neither surgery nor radiotherapy had a median survival of 2 months (p < 0.001). Multivariate analysis showed that radiotherapy significantly improved cancer-specific survival (hazard ratio [HR], 0.43, 95% confidence interval [CI] 0.38-0.49) after adjusting for surgery, tumor size, gender, ethnicity, and age at diagnosis. Other factors associated with Cancer-specific survival included surgery, tumor size, age at diagnosis, and ethnicity. Analysis using overall survival as the endpoint yielded very similar results. Conclusions: Elderly

    Full Text Available Background. Iron status in patients with sickle cell anaemia is a matter of continuing investigation. Objective. This paper aims to determine the serum iron status of under-five, sickle cell anaemia patients. Methods. The study spanned from December 2009 to February 2010 at the Consultant Outpatient Clinics involving 97 HbSS subjects and 97 age- and sex-matched HbAA controls. Biochemical iron status was assayed in subjects and controls. Results. Age range of the children was seven months to five years, with a mean of 30.6 (±15.97 months. Irrespective of gender, mean serum iron values were higher in HbAA controls than their HbSS counterparts but the observed difference was not significant ( and 0.111, resp.. The mean total iron binding capacity values of males and females were also not significantly different for sickle cell anaemia subjects and controls (. Males and females with HbAA had significantly lower serum ferritin when compared with their HbSS counterparts. Irrespective of gender, mean transferrin saturation was lower in HbSS subjects but the difference was not statistically significant (. Conclusion. Children with sickle cell anaemia have higher serum ferritin than controls, implying relatively higher iron content in the reticuloendothelial cells.

    Patients with chronic hypoxaemia develop secondary polycythaemia that improves oxygen-carrying capacity. Therefore, normal haemoglobin and haematocrit values in the presence of chronic arterial hypoxaemia in cystic fibrosis constitute \\'relative anaemia\\'. We sought to determine the cause of this relative anaemia in patients with cystic fibrosis. We studied haematological indices and oxygen saturation in healthy volunteers (n=17) and in adult patients with cystic fibrosis (n=15). Patients with cystic fibrosis had lower resting arterial oxygen saturation when compared with normal volunteers (P<0.0001), and exercise led to a greater reduction in arterial oxygen saturation (P<0.0001). However, haemoglobin and haematocrit values in patients with cystic fibrosis did not significantly differ from normal volunteers. Serum iron (P=0.002), transferrin (P=0.02), and total iron-binding capacity (P=0.01) were lower in patients with cystic fibrosis. There were no significant differences in serum ferritin, percentage iron saturation, serum erythropoietin or red cell volume between the groups. The data presented demonstrate a characteristic picture of anaemia of chronic disease in adult patients with cystic fibrosis, except for normal haemoglobin and haematocrit values. Normal haemoglobin and haematocrit values in patients with cystic fibrosis appear to represent a combination of the effects of arterial hypoxaemia promoting polycythaemia, counterbalanced by chronic inflammation promoting anaemia of chronic disease.

  6. HIF prolyl hydroxylase inhibitors for the treatment of renal anaemia and beyond.

    2016-03-01

    Small-molecule stabilizers of hypoxia inducible factor (HIF) are being developed for the treatment of renal anaemia. These molecules inhibit prolyl hydroxylase domain-containing (PHD) enzymes, resulting in HIF activation and increased production of erythropoietin. Currently, renal anaemia is treated with recombinant human erythropoietin or related analogues, referred to as conventional erythropoiesis stimulating agents (ESAs). Advantages of PHD enzyme inhibitors over conventional ESAs include their oral administration and their simpler - and potentially cheaper - production. Importantly, inhibition of PHD enzymes is likely to have a range of consequences other than increasing levels of erythropoietin, and these effects could be beneficial - for instance by reducing the need for parenteral iron - but might in some instances be harmful. Several companies are currently testing PHD enzyme inhibitors in patients with renal anaemia and have reported clear evidence of efficacy without serious safety concerns. A central question that current studies are beginning to address is whether using PHD enzyme inhibitors will influence hard end points, including mortality and the rate of cardiovascular events. In terms of approaches to therapy, the exquisite specificity of conventional ESAs is a striking contrast to the pleiotropic effects of activating HIF. Excitingly, PHD inhibitors could also be useful for conditions besides renal anaemia, such as protection from ischaemic injury. PMID:26656456

    Full Text Available BACKGROUND: Given that micronutrient deficiency, neglected intestinal parasitic infections (IPIs and poor socioeconomic status are closely linked, we conducted a cross-sectional study to assess the relationship between IPIs and nutritional status of children living in remote and rural areas in West Malaysia. METHODS/FINDINGS: A total of 550 children participated, comprising 520 (94.5% school children aged 7 to 12 years old, 30 (5.5% young children aged 1 to 6 years old, 254 (46.2% boys and 296 (53.8% girls. Of the 550 children, 26.2% were anaemic, 54.9% iron deficient and 16.9% had iron deficiency anaemia (IDA. The overall prevalence of helminths was 76.5% comprising Trichuris trichiura (71.5%, Ascaris lumbricoides (41.6% and hookworm infection (13.5%. It was observed that iron deficiency was significantly higher in girls (p = 0.032 compared to boys. Univariate analysis demonstrated that low level of mother's education (OR = 2.52; 95% CI = 1.38-4.60; p = 0.002, non working parents (OR = 2.18; 95% CI = 2.06-2.31; p = 0.013, low household income (OR = 2.02; 95% CI = 1.14-3.59; p = 0.015, T. trichiura (OR = 2.15; 95% CI = 1.21-3.81; p = 0.008 and A. lumbricoides infections (OR = 1.63; 95% CI = 1.04-2.55; p = 0.032 were significantly associated with the high prevalence of IDA. Multivariate analysis confirmed that low level of mother's education (OR = 1.48; 95 CI% = 1.33-2.58; p<0.001 was a significant predictor for IDA in these children. CONCLUSION: It is crucial that a comprehensive primary health care programme for these communities that includes periodic de-worming, nutrition supplement, improved household economy, education, sanitation status and personal hygiene are taken into consideration to improve the nutritional status of these children.

  12. Severe anaemia is not associated with HIV-1 env gene characteristics in Malawian children

    Full Text Available Abstract Background Anaemia is the most common haematological complication of HIV and associated with a high morbidity and a poor prognosis. The pathogenesis of HIV-associated anaemia is poorly understood and may include a direct effect of HIV on erythropoiesis. In vitro studies have suggested that specific HIV strains, like X4 that uses the CXCR4 co-receptor present on erythroid precursors, are associated with diminished erythropoiesis. This co-receptor affinity is determined by changes in the hypervariable loop of the HIV-1 envelope genome. In a previous case-control study we observed an association between HIV and severe anaemia in Malawian children that could not be fully explained by secondary infections and micronutrient deficiencies alone. We therefore explored the possibility that alterations in the V1-V2-V3 fragment of HIV-1 were associated with severe anaemia. Methods Using peripheral blood nucleic acid isolates of HIV-infected children identified in the previous studied we assessed if variability of the V1-V2-V3 region of HIV and the occurrence of X4 strains were more common in HIV-infected children with (cases, n = 29 and without severe anaemia (controls, n = 30. For 15 cases bone marrow isolates were available to compare against peripheral blood. All children were followed for 18 months after recruitment. Results Phylogenetic analysis showed that HIV-1 subtype C was present in all but one child. All V1-V2-V3 characteristics tested: V3 charge, V1-V2 length and potential glycosylation sites, were not found to be different between cases and controls. Using a computer model (C-PSSM four children (7.8% were identified to have an X4 strain. This prevalence was not different between study groups (p = 1.00. The V3 loop characteristics for bone marrow and peripheral blood isolates in the case group were identical. None of the children identified as having an X4 strain developed a (new episode of severe anaemia during follow up. Conclusion

    Full Text Available Abstract Background A Phase 1-2b study of the blood stage malaria vaccine AMA1-C1/Alhydrogel was conducted in 336 children in Donéguébougou and Bancoumana, Mali. In the Phase 2 portion of the study (n = 300, no impact on parasite density or clinical malaria was seen; however, children who received the study vaccine had a higher frequency of anaemia (defined as haemoglobin Methods To further investigate the possible impact of vaccination on anaemia, additional analyses were conducted including patients from the Phase 1 portion of the study and controlling for baseline haemoglobin, haemoglobin types S or C, alpha-thalassaemia, G6PD deficiency, and age. A multiplicative intensity model was used, which generalizes Cox regression to allow for multiple events. Frailty effects for each subject were used to account for correlation of multiple anaemia events within the same subject. Intensity rates were calculated with reference to calendar time instead of time after randomization in order to account for staggered enrollment and seasonal effects of malaria incidence. Associations of anaemia with anti-AMA1 antibody were further explored using a similar analysis. Results A strong effect of vaccine on the incidence of anaemia (risk ratio [AMA1-C1 to comparator (Hiberix]= 2.01, 95% confidence interval [1.26,3.20] was demonstrated even after adjusting for baseline haemoglobin, haemoglobinopathies, and age, and using more sophisticated statistical models. Anti-AMA1 antibody levels were not associated with this effect. Conclusions While these additional analyses show a robust effect of vaccination on anaemia, this is an intensive exploration of secondary results and should, therefore, be interpreted with caution. Possible mechanisms of the apparent adverse effect on haemoglobin of vaccination with AMA1-C1/Alhydrogel and implications for blood stage vaccine development are discussed. The potential impact on malaria-associated anaemia should be closely

    Inequitable access to healthcare has a profound impact on the health of marginalised groups that typically suffer an excess burden of infectious disease morbidity and mortality. The Yanomami are traditionally semi-nomadic people living in widely dispersed communities in Amazonian Venezuela and Brazil. Only communities living in the vicinity of a health post have relatively constant access to healthcare. To monitor the improvement in the development of Yanomami healthcare a cross-sectional survey of 183 individuals was conducted to investigate malaria and anaemia prevalence in communities with constant and intermittent access to healthcare. Demographic and clinical data were collected. Malaria was diagnosed by microscopy and haemoglobin concentration by HemoCue. Prevalence of malaria, anaemia, splenomegaly, fever and diarrhoea were all significantly higher in communities with intermittent access to healthcare (anaemia 80.8% vs. 53.6%, P<0.001; malaria 18.2% vs. 6.0%, P=0.013; splenomegaly 85.4% vs.12.5%, P<0.001; fever 50.5% vs. 28.6%, P=0.003; diarrhoea 30.3% vs.10.7% P=0.001). Haemoglobin level (10.0 g/dl vs. 11.5 g/dl) was significantly associated with access to healthcare when controlling for age, sex, malaria and splenomegaly (P=0.01). These findings indicate a heavy burden of anaemia in both areas and the need for interventions against anaemia and malaria, along with more frequent medical visits to remote areas. PMID:18405929

    Full Text Available Introduction: The prevalence of anaemia among children less than five years of age in India is around 70%. Anaemia in young children puts them at a higher risk of experiencing health problems such as stunted growth, mental retardation, and increased susceptibility to infectious diseases. The present study was undertaken to evaluate the effectiveness of IFA supplementation (daily vs. biweekly vs. weekly regime on haemoglobin levels of young children. Materials and Methods: A total 740 children in age group of six months to five years were included in this community based interventional study using Systemic random sampling. The children having mild to moderate anaemia were then divided into three groups A, B and C by simple random sampling and were given Iron and Folic acid supplementation daily, biweekly and weekly respectively. Follow up data was collected after 3 months and analysed using appropriate tests. Results: Prevalence of Anaemia was 91.1% among study participants. Comparison after 3 months showed significant change in haemoglobin levels in all three groups with mean improvement of 1.31 gm%, 0.89 gm% and 0.85 gm% in group A, B and C respectively. However, no significant difference was noted among the groups in pre as well as post intervention phase. Conclusion: Weekly regime is as effective as daily or biweekly regime in improving haemoglobin levels in children. Moreover, it has better compliance, lesser side effects and cost of therapy. So, the same should be recommended for prophylaxis as well as treatment of mild to moderate anaemia cases. [Natl J Med Res 2014; 4(1.000: 33-36

    Full Text Available BACKGROUND: Studies conducted in high income countries have shown that anaemia is a common medical condition among older people, but such data are scarce in Africa. The objectives of this study were to estimate the prevalence, types, risk factors and clinical correlates of anaemia in older people. METHODS: Participants were aged (≥ 50 years recruited from a general population cohort from January 2012 to January 2013. Blood samples were collected for assessing hemoglobin, serum ferritin, serum vitamin B12, serum folate, C-reactive protein, malaria infection and stool samples for assessment of hookworm infection. HIV status was assessed using an algorithm for HIV rapid testing. Questionnaires were used to collect data on sociodemographic characteristics and other risk factors for anaemia. RESULTS: In total, 1449 people participated (response rate 72.3%. The overall prevalence of anaemia was 20.3 % (95% CI 18.2-22.3%, and this was higher for males (24.1%, 95% CI=20.7-27.7% than females (17.5%, 95% CI=15.0-20.1%. In males, the prevalence of anaemia increased rapidly with age almost doubling between 50 and 65 years (p-trend<0.001. Unexplained anaemia was responsible for more than half of all cases (59.7%. Anaemia was independently associated with infections including malaria (OR 3.49, 95% CI 1.78-6.82, HIV (OR 2.17, 1.32-3.57 heavy hookworm infection (OR 3.45, 1.73-6.91, low fruit consumption (OR 1.55, 1.05-2.29 and being unmarried (OR 1.37 , 95% CI 1.01-1.89. However, the odds of anaemia were lower among older people with elevated blood pressure (OR 0.47, 95% CI 0.29-0.77. CONCLUSION: Anaemia control programmes in Uganda should target older people and should include interventions to treat and control hookworms and educational programs on diets that enhance iron absorption. Clinicians should consider screening older people with HIV or malaria for anaemia. Further studies should be done on unexplained anaemia and serum ferritin levels that predict

  19. Mucosal regeneration during radiotherapy

    International Nuclear Information System (INIS)

    Background and purpose: Regeneration of the aerodigestive mucosa is known to occur during conventionally fractionated radiotherapy. The circumstances surrounding its time of onset and magnitude are not well understood, however. Material and methods: Mucosal reactions were observed in 100 patients undergoing conventionally fractionated treatment at 2 Gy/day over 7 weeks and 88 receiving accelerated treatment at 1.8 Gy twice daily over 3(1(2)) weeks on the Trans Tasman Radiation Oncology Group head and neck cancer trials. Similar observations in 61 patients treated palliatively at dose rates between 0.8 and 240 Gy/h using ten 3.0-4.2 Gy fractions over 2 weeks are compared. Results: Several findings emerged from these studies: 1. Reactions evolved more quickly at oropharyngeal sites than in the hypopharynx. 2. Reactions at both sites evolved more rapidly at greater rates of dose accumulation. 3. The timing of reactions suggested the presence of a strong regenerative mucosal response that started before the manifestation of 'patchy' (grade II) mucosal reactions. 4. The regenerative response was strong enough to 'make good' damage accumulated at a rate of 2 Gy/day in over a third of cases. 5. The linear quadratic model without time correction failed to provide an adequate prediction of the frequency or intensity of mucosal reactions produced by any of the regimes. A simple model of the regenerative response is presented. Conclusions: This study suggests that the timing and magnitude of the regenerative response vary between sites and individuals but are linked to the amount of epithelial cellular depletion occurring during treatment

  20. Quality Assurance in Radiotherapy

    Science.gov (United States)

    Mckenzie, Alan

    A common feature of the Radiotherapy Centres where there have been major accidents involving incorrect radiotherapy treatment is that they did not operate good Quality Assurance systems. A Quality Assurance system is sometimes called a Quality Management system, and it is designed to give assurance that quality standards are being met. One of the "spin offs" from operating a Quality Management system is that it reduces the likelihood of a radiotherapy accident. A detailed account of how to set up a quality system in radiotherapy has been given in an ESTRO booklet.2

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Cancer is a major cause of mortality worldwide (1). A large fraction of cancer patients undergo external radiotherapy, delivering a lethal dose of radiation to the patient’s tumour(s). The main problem with this approach is the collateral damage caused to healthy, surrounding tissue and the side...... damage produced by Low-LET radiation used in current radiotherapy (2-3) Considerable efforts have been made in the past twenty years to develop Auger emitter-based radiotherapy However, previous studies lack precise measurement of RBE, which is the fundamental factor defining the relationship between...... local radiation dose and biological damage done for the given Auger emitter, thereby brought the development to a halt. We believe we have the techniques to quantify the biological damage done for a given Auger emitter and thereby pushing the development of Auger emitterbased radiotherapy into reality...

  3. The effects of radiotherapy and surgery on the sexual function of women treated for cervical cancer

    International Nuclear Information System (INIS)

    Purpose: This study investigated the short- and medium-term effects of pelvic radiotherapy and surgery on the sexual function of women treated for cervical cancer. Methods and Materials: Sixteen women with Stages I, II, or III disease referred for radiotherapy treatment were assessed. Six had undergone prior hysterectomy. The women were assessed with questionnaires prior to radiotherapy, at completion of radiotherapy, and at 6 weeks and 14 weeks after radiotherapy treatment. The clinical findings at routine follow-up were noted. Results: The study showed significant changes in sexual activity and satisfaction as a result of treatment. This was due to a number of physical and psychological factors. The level of sexual activity was lowest at completion of radiotherapy treatment. A feeling of vaginal shortening was the most frequent reason and was more common in women who were treated with surgery and radiotherapy. Dyspareunia, bleeding, and concern of bleeding and/or recurrence were all significant factors. Conclusions: The questionnaires were an effective way of assessing women's sexual function. Radiotherapy caused sexual dysfunction in one-half of women. Combined treatment with radiotherapy and surgery results in a higher risk than radiotherapy alone. Women with cervical cancer and undergoing radiotherapy treatment require considerable counseling and support

    Hepatitis-associated aplastic anaemia (HAAA) is an uncommon but distinct variant of aplastic anaemia in which pancytopenia and bone marrow failure appears 2-3 months after an acute attack of hepatitis. Although bilateral vision loss may rarely be the initial presentation of aplastic anaemia, no such report is known in HAAA. Here the authors report such a case presenting with large premacular subhyaloid haemorrhages secondary to severe anaemia and thrombocytopenia. Anaemic hypoxic damage to the vessel wall together with increased cardiac output and low platelet counts are interacting causal factors in the development of bleeding. Though these haemorrhages are benign and usually improve spontaneously, the presence of blood may cause permanent macular changes before it resolves. Posterior hyaloidotomy enabled rapid resolution of premacular subhyaloid haemorrhage thereby restoring vision and preventing need for vitreo-retinal surgery. These patients should be advised to refrain from valsalva manoeuvres, ocular rubbing and vigorous exercise to prevent ocular morbidity. PMID:22674943

    Anaemia is a negative prognostic factor for patients with heart failure and impaired renal function, but its role in stroke patients is unknown. Furthermore, anaemia has been shown to influence the level of N-terminal pro-brain natriuretic peptide (NT-proBNP), but this is only investigated in...... patients with heart failure, not in stroke patients. Two-hundred-and-fifty consecutive, well-defined ischemic stroke patients were investigated. Mortality was recorded at 6 months follow-up. Anaemia was diagnosed in 37 patients (15%) in whom stroke severity was worse than in the non-anaemic group, whilst...... the prevalence of renal affection, smoking and heart failure was lower. At 6 months follow-up, 23 patients were dead, and anaemia had an odds ratio of 4.7 when adjusted for age, Scandinavian Stroke Scale and a combined variable of heart and/or renal failure and/or elevation of troponin T using...

    Full Text Available Abstract Background Hyperlactataemia is often associated with a poor outcome in severe malaria in African children. To unravel the complex pathophysiology of this condition the relationship between plasma lactate levels, parasite density, pro- and anti-inflammatory cytokines, and haemozoin-containing leucocytes was studied in children with severe falciparum malarial anaemia. Methods Twenty-six children with a primary diagnosis of severe malarial anaemia with any asexual Plasmodium falciparum parasite density and Hb Results Parasite density was associated with lactate levels on admission (r = 0.56, P r = 0.60, P = 0.003 and r = -0.46, P = 0.02, respectively. These associations were not found in controls with uncomplicated malarial anaemia. Conclusion These data suggest that blood stage parasites, haemozoin and low levels of IL-12 may be associated with the development of hyperlactataemia in severe malarial anaemia.

    Objective: To investigate the prevalence and socio-demographic factors associated with iron deficiency anaemia among blood donors in Sokoto, North Western, Nigeria using a combination of haemoglobin haematocrit and serum ferritin measurements. Methods: One hundred and fifty consecutively recruited whole blood donors, comprising of 148 (98.7%) family replacement donors and 2 (1.3%) voluntary non-remunerated donors aged 18-60 years and mean age 39±21 years constituted the subjects for this study. The full blood count was carried out using Mythic 22 CT fully automated haematology analyser (Orphee SA, Switzerland). Serum was tested for ferritin using a human ferritin enzyme immunoassay kit-ACCU Diag™ ELISA Ferritin kit (Diagnostic Automation/Cortez Diagnostic Inc. California, USA). Results: The prevalence of anaemia (haemoglobin<11.0 g/dL) was evident in 24 (16%) and iron deficiency anaemia (serum ferritin<12 ng/mL+haemoglobin<11 g/dL) in 5 (10%) of donors. The haemoglobin and ferritin levels was significantly lower among regular voluntary remunerated blood donors (13.50±0.00 and 34.88±0.00) compared to family replacement donors (14.10±2.40 and 74.12±45.20) respectively (P=0.01 and 0.05 respectively). The mean haemoglobin and ferritin level was compared among donors based on gender. The haemoglobin and ferritin was significantly higher among male donors (14.20±2.00, 78.02±49.10) compared to female donors (12.35±2.5 and 42.20±32.13) (P=0.01). The mean haemoglobin and ferritin level was compared among donors based on occupational groups. The haemoglobin and ferritin was significantly higher among civil servants compared to farmers and students (P=0.01). Conclusions: Iron deficiency anaemia is prevalent among blood donors in Sokoto, North Western, Nigeria. There is need to include routine ferritin in the blood donor testing protocol in the area to enable the diagnosis of donors with latent iron deficiency anaemia to facilitate iron supplementation for regular

    The indications of radiotherapy for skin cancers are not clearly defined because of the lack of randomised trials or prospective studies. For basal cell carcinomas, radiotherapy frequently offers a good local control, but a randomized trial showed that surgery is more efficient and less toxic. Indications of radiotherapy are contra-indications of surgery for patients older than 60, non-sclerodermiform histology and occurring in non-sensitive areas. Adjuvant radiotherapy could be proposed to squamous cell carcinomas, in case of poor prognostic factors. Dose of 60 to 70Gy are usually required, and must be modulated to the size of the lesions. Adjuvant radiotherapy seems beneficial for desmoplastic melanomas but not for the other histological types. Prophylactic nodal irradiation (45 to 50Gy), for locally advanced tumours (massive nodal involvement), decreases the locoregional failure rate but do not increase survival. Adjuvant radiotherapy (50 to 56Gy) for Merckel cell carcinomas increases also the local control rate, as demonstrated by meta-analysis and a large epidemiological study. Nodal areas must be included, if there is no surgical exploration (sentinel lymph node dissection). Kaposi sarcomas are radiosensitive and could be treated with relatively low doses (24 to 30Gy). Also, cutaneous lymphomas are good indications for radiotherapy: B lymphomas are electively treated with limited fields. The role of total skin electron therapy for T-lymphomas is still discussed; but palliative radiotherapy is very efficient in case of cutaneous nodules. PMID:27522189

  14. The impact of renal insufficiency and anaemia on survival in patients with cardiovascular disease: a cohort study.

    LENUS (Irish Health Repository)

    Anderson, Jocelyn

    2009-01-01

    BACKGROUND: The simultaneous occurrence of cardiovascular disease (CVD), kidney disease, and anaemia is associated with increased morbidity and mortality. In the community setting, little data exists about the risk associated with milder levels of anaemia when it is present concurrently with CVD and chronic kidney disease (CKD). The aim of this study was to establish the prevalence of CKD and anaemia in patients with CVD in the community and to examine whether the presence of anaemia was associated with increased morbidity and mortality. METHODS: This study was designed as a retrospective cohort study and involved a random sample of 35 general practices in the West of Ireland. A practice-based sample of 1,609 patients with established cardiovascular disease was generated in 2000\\/2001 and followed for five years. The primary endpoint was death from any cause. Statistical analysis involved using one-way ANOVA and Chi-squared tests for baseline data and Cox proportional-hazards models for mortality data. RESULTS: Of the study sample of 617 patients with blood results, 33% (n = 203) had CKD while 6% (n = 37) had CKD and anaemia. The estimated risk of death from any cause, when compared to patients with cardiovascular disease only, was almost double (HR = 1.98, 95% CI 0.99 to 3.98) for patients with both CVD and CKD and was over 4 times greater (HR = 4.33, 95% CI 1.76 to 10.68) for patients with CVD, CKD and anaemia. CONCLUSION: In patients with cardiovascular disease in the community, chronic kidney disease and anaemia occur commonly. The presence of chronic kidney disease carries an increased mortality risk which increases in an additive way with the addition of anaemia. These results suggest that early primary care diagnosis and management of this high risk group may be worthwhile.

    Full Text Available INTRODUCTION: Brain tumors are the most common solid tumors and the second largest group of neoplasms diagnosed in childhood. Treatment includes surgery, radiotherapy, and chemotherapy. However, radiotherapy can cause complications, e.g., cognitive deficits. CASE DESCRIPTION: We describe the case of a child diagnosed with a brain tumor evaluated before and after radiotherapy to investigate cognitive decline after treatment. The results showed a decline in Intelligence Quotient (IQ scores and reversal of the predominance of verbal and nonverbal skills. After radiotherapy, the subject showed slowness, academic deficits, and difficulties learning new information. COMMENTS: Even though the post-treatment evaluation showed scores compatible with the average, comparison between pre- and post-treatment evaluations demonstrated the impact of radiotherapy on the subject's cognitive profile. These results highlight the importance of evaluating patients who undergo radiotherapy before and after treatment and understanding neuropsychological scores associated with the subjects' complaints.

    Necrotizing fasciitis (NF) is an uncommon soft-tissue infection in children that carries a high mortality rate. We present a 15-year-old girl with chronic pancytopenia secondary to Fanconi anaemia who developed extensive NF of the lower limb, which unfortunately resulted in a fatal outcome. Immunodeficiency is a known risk factor for the development of this condition. The findings in this case demonstrate that patients with Fanconi anaemia may be susceptible to NF and that the clinical course may be more aggressive due to underlying immunosuppression. Prompt diagnosis of NF is vital in order to initiate appropriate treatment and to optimize patient outcome. Radiological investigation demonstrated extensive soft-tissue gas and destruction affecting the entire lower limb, abdominal wall and retroperitoneum, which led to timely definitive diagnosis and management.

    Coeliac disease (CD) occurs in individuals sensitive to gluten protein contained in wheat products. It affects at least 1:100 children and may present with extra-intestinal manifestations such as iron deficiency anaemia, short stature and delay in puberty. A case of severe iron deficiency anaemia as a manifestation of CD is described here. There is a need to raise awareness among health professionals about CD and its extra-intestinal presentations. Suspicion of CD should lead to antibody screening tests and positive results should be followed by an intestinal biopsy for a definitive diagnosis. Involvement of a paediatric dietitian is vital in the management of CD and lifelong adherence to a gluten-free diet is necessary. We hope this article leaves the reader with a heightened awareness about CD and will lead to appropriate early referral to the paediatric services. PMID:20518373

In thalassaemic children the calculated parameters denote that the shorting of the mean cell life is due to early senescence alone, while there is some evidence that in thalassaemic adults additional extracellular destruction mechanisms participate as well. Red cell survival curves from patients with sickle-cell anaemia and s-..beta..-thalassaemia resemble each other, while their parameters indicate an initial rapid loss of radioactivity, early senescence and the presence of extracellular red cell destruction factors.

    A seven-year-old flat-coated retriever presented with a history of lethargy, dyspnoea and inappetence of several days' duration. Clinical examination revealed pale mucous membranes and tachypnoea, and haematology demonstrated marked autoagglutination. Thoracic radiographs revealed an increased opacity in the perihilar region. The owners declined further evaluation and the dog was treated symptomatically with immunosuppressive doses of prednisolone and azathioprine. The dog's demeanour improved, although it was eventually euthanased seven weeks later because of dysphagia and worsening dyspnoea. Postmortem examination revealed a widespread, poorly differentiated sarcoma involving the lungs, pericardium, thoracic lymph nodes and spleen. Immune-mediated haemolytic anaemia is a well recognised condition in dogs and is occasionally associated with neoplastic conditions. This is the first case report to describe immune-mediated haemolytic anaemia associated with a diffuse, poorly differentiated sarcoma. PMID:14756205

    The identification process based on measuring the level of haemoglobin and the classification of red blood cells using microscopic examination of blood smears is the principal way to diagnose anaemia. This paper presents a proposed algorithm for detecting some anaemia types like sickle and elliptocytosis and trying to count them with healthy ones in human red blood smears based on the circular Hough transform and some morphological tools. Some cells with unknown shapes (not platelets or white cells) also have been detected. The extracted data from the detection process has been analyzed by neural network. The experimental results have demonstrated high accuracy, and the proposed algorithm has achieved the highest detection of around 98.9% out of all the cells in 27 microscopic images. Effectiveness rates up to 100%, 98%, and 99.3% have been achieved by using neural networks for sickle, elliptocytosis and cells with unknown shapes, respectively.

    2016-05-01

    Malaria and anaemia which jointly account for high proportion of morbidity and mortality among young children in developing countries have been individually studied using binary regression model. We adopt geoadditive latent variable model for binary/ordinal indicators to analyze the influence of variables of different types on the morbidity among young children in Nigeria. Latent variable models allow for the analysis of multidimensional response variables that reveal the indicator's underlying relationship that are caused by the latent variables. We extend the structural model to a semi-parametric geoadditive model in order to quantify the joint spatial structure of morbidity from malaria and anaemia. Findings revealed substantial geographical variations and the generated maps can guide policy makers and donors on how to prudently utilize the scarce resources for designing more cost-effective interventions.

    At present lung tumor radiation therapy has entered the accurate radiotherapy era. Precise radiotherapy includes intensity modulated radiotherapy (IMRT), image-guided radiotherapy (IGRT) and stereotactic body radiotherapy (SBRT). During the process of implementing precise radiotherapy, these problems should be fully considered to ensure executing precise radiotherapy accurately: patient positioning, controlling of the lung tumor motion, selecting of image techniques, PTV margin, dose prescrip...

  12. Iron deficiency and malaria as determinants of anaemia in African children

    OpenAIRE

    Verhoef, H.

    2001-01-01

    Approximately three quarters of east African children <5 y of age suffer from anaemia, which is due, at least in part, to malaria and iron deficiency. In children in areas of seasonal malaria, the benefits of iron supplementation may not outweigh possible inherent risks of adverse effects caused by malaria. Intermittent administration of sulfadoxine-pyrimethamine (SP) might improve haemoglobin concentrations while allowing children to develop protective immunity against severe disease and ...

    Recurrent gastrointestinal haemorrhage is an uncommon manifestation of systemic sclerosis. We report a case of gastrointestinal bleeding due to gastric antral vascular ectasia (GAVE) in a patient with systemic sclerosis. Failure to recognise the condition as a cause of gastrointestinal bleeding may delay the instigation of appropriate treatment. GAVE should be considered in the differential diagnosis of anaemia in patients with autoimmune conditions such as systemic sclerosis and primary biliary cirrhosis.

  13. Giant Brunner’s gland adenoma as an unusual cause of anaemia: report of a case

    International Nuclear Information System (INIS)

    Brunner’s gland adenoma (BGA) is a rare benign duodenal tumour proliferating from Brunner’s glands. Here, we present a giant BGA leading to anaemia, with its clinical, endoscopic, radiological, surgical and pathological findings. A 48-year-old Turkish man complained of a six months history of vague epigastric discomfort, loss of appetite and nausea after meals without vomiting. The physical examination had no unremarkable finding. Laboratory findings, including liver function tests, were within normal limits except a hypochromic, microcytic anaemia. The upper gastrointestinal endoscopic examination revealed a lobulated, red, polypoid tumour with a smooth surface covered with normal mucosa. The tumour was located on the anterior surface of duodenal bulb and had a wide base measuring 3.5 × 4 cm in size. Endoscopic ultrasonography revealed a submucosal polypoid mass located at the anterior surface of duodenal bulb. The endoscopic excision was tried but was not successful. The patient was operated and transduodenal polypectomy was done. The postoperative period was uneventful and the pathologic diagnosis was assessed as Brunner’s gland adenoma. During the follow-up period, the endoscopic examination was normal at 12th month postoperatively. BGA is a rare benign cause of anaemia that can be treated with excellent results

    Objective:To determin the extent to which parvovirus B19 (B19V) and co-infection of B19V and malaria contribute to risk of anaemia in children. Methods: B19V DNA and malaria parasites were screened for 234 children at the PML Children’s Hospital in Accra. The role of B19V and co-infection with B19V and malaria in anaemia was evaluated by analysing full blood cell counts, malaria and B19V DNA results from these children. Results: The prevalence of B19V, malaria and co-infection with B19V and malaria was 4.7%, 41.9%and 2.6%, respectively. Malaria posed a greater risk in the development of mild anaemia compared to severe anaemia (OR=5.28 vrs 3.15) whereas B19V posed a higher risk in the development of severe anaemia compared to mild anaemia (OR=4.07 vrs 1.00) from a non-anaemic child. Persons with co-infection with B19V and malaria had 2.23 times the risk (95%CI=0.40-12.54) of developing severe anaemia should they already have a mild anaemia. The degree of anaemia was about three times affected by co-infection (Pillai’s trace=0.551, P=0.001) as was affected by malaria alone (Pillai’s trace=0.185, P=0.001). B19V alone did not significantly affect the development of anaemia in a non-anaemic child. Microcytic anaemia was associated with B19V and co-infection with B19V and malaria more than normocytic normochromic anaemia. Conclusions: B19V was associated with malaria in cases of severe anaemia. The association posed a significant risk for exacerbation of anaemia in mild anaemic children. B19V and co-infection with B19V and malaria may be associated with microcytic anaemia rather than normocytic normochromic anaemia as seen in cases of B19V infection among persons with red cell abnormalities.

    Full Text Available BACKGROUND: In malaria endemic countries, children who have experienced an episode of severe anaemia are at increased risk of a recurrence of anaemia. There is a need to find ways of protecting these at risk children from malaria and chemoprevention offers a potential way of achieving this objective. METHODS: During the 2003 and 2004 malaria transmission seasons, 1200 Gambian children with moderate or severe anaemia (Hb concentration <7 g/dL were randomised to receive either monthly sulfadoxine-pyrimethamine (SP or placebo until the end of the malaria transmission season in which they were enrolled, in a double-blind trial. All study subjects were treated with oral iron for 28 days and morbidity was monitored through surveillance at health centres. The primary endpoint was the proportion of children with moderate or severe anaemia at the end of the transmission season. Secondary endpoints included the incidence of clinical episodes of malaria during the surveillance period, outpatient attendances, the prevalence of parasitaemia and splenomegaly, nutritional status at the end of the malaria transmission season and compliance with the treatment regimen. RESULTS: The proportions of children with a Hb concentration of <7 g/dL at the end of the malaria transmission season were similar in the two study groups, 14/464 (3.0% in children who received at least one dose of SP and 16/471 (3.4% in those who received placebo, prevalence ratio 0.89 (0.44,1.8 P = 0.742. The protective efficacy of SP against episodes of clinical malaria was 53% (95% CI 37%, 65%. Treatment with SP was safe and well tolerated; no serious adverse events related to SP administration were observed. Mortality following discharge from hospital was low among children who received SP or placebo (6 in the SP group and 9 in the placebo group respectively. CONCLUSIONS: Intermittent treatment with SP did not reduce the proportion of previously anaemic children with moderate or severe anaemia

    Full Text Available Objective: To determine the prevalence of iron deficiency and megaloblastic anaemia at booking in the Specialist Hospital Gombe. Patients and methods:This was a cross sectional study of 461 women attending the antenatal clinic for their booking visit. The capillary technique was used for the estimation of the packed cell volume (PM/ while the morphologic type of anaemia was determined by the blood film appearance. The age, parity social class and gestational age at booking were obtained and analyzed. Results:Among the 461 women studied, 239 were anaemic thus making the prevalence of anaemia at booking to be 51.8%. Most, 67.4% were mildly anaemic, 30.5% were moderately anaemic while 2.1 % were severely anaemic. Three hundred and sixteen, (68.5% of the women booked in the second trimester while only 3.0% booked in the first trimester. The majority of the women, 293 (63.5% were in lower social class. Of the 239 anaemic women, 155 (64.9% had features of pure iron deficiency anaemia while only 1(0.4% had features of pure megaloblastic anaemia. Eighty three (34.7% had dim orphic blood picture while 238 (99.6% in total had features of iron deficiency anaemia. Although not anaemic by PCV the blood film of 26(5.6% showed features of pure iron deficiency. Conclusion: The contribution of iron deficiency to anaemia in pregnancy is exceedingly high. This further supports the continued use of iron supplements for all pregnant women preferably at no cost in the short run and economic empowerment of the women folk in the long run.

It is the commonest medical disorder of pregnancy and a major cause of morbidity and mortality in most developing countries. Aim: This study aimed at assessing the prevalence of anaemia in pregnancy and to identify the confounding socio-demographic factors. Methods: This is a cross-sectional descriptive study designed to determine the socio-demographic characteristics and prevalence of anaemia among pregnant women at their booking antenatal visit in a teaching hospital in South-western Nigeria. Pregnant women were enrolled for the study by consecutive sampling method at their first antenatal visit and the packed cell volume (PCV was used to assess level of anaemia. Socio-demographic information was obtained from the case records of the enrolled women. Results: One hundred and thirty-eight (27.6% of the 500 enrolled women were found to be anaemic at the time of antenatal booking. Anaemia were more prevalent among primigravidae (33.9% than the multigravidae (25.3%, although this difference was not statistically significant (P=0.079. Anaemia was higher among women with no formal education, those unemployed, single mothers and women with sickle cell traits. Conclusion: Anaemia in pregnancy remains a major health challenge in Nigeria with primigravidae identified as being those at most risk. So also are pregnant teenagers and women that book late for antenatal care (ANC. It is therefore important to educate women on early ANC booking and the need for compliance with prescribed medications in pregnancy.

When several imaging devices work based on DICOM standard; they can connect to each other without any interface. There are many applications for DICOM standard in radiotherapy; however its main usage is in imaging. It has other applications such as RT Structure Set, RT Dose, RT Plan and RT Brachy Treatment. "nNow DICOM is a complete and widespread standard to use in radiotherapy. Most of the radiotherapy machines have ability to use DICOM. Before installing a new Linac, it is necessary to predict all aspects of DICOM standard in this device. Therefore, as regards to entrance of 12 Linac to Iran, it is important to have enough knowledge about it. This article is a review about development of DICOM in radiotherapy. We try to stress on DICOM applications and abstain from technological agenda.

  19. Radiotherapy cure: safety

    International Nuclear Information System (INIS)

    In radiotherapy, a precisely measured dose of ionising radiation is directed at a limited tumour area so as not to damage healthy tissues. The most important form of therapy is external radiation therapy given by means of radiotherapy equipment. The bigger the tumour, the more cancer cells it contains and the higher the radiation dose that is needed to destroy the tumour. Different cancer types respond differently to radiation. Healthy tissues also respond in different ways to radiotherapy, e.g. the reaction may come during the treatment or later. The growth of some cancer types accelerates in two to four weeks after the initiation of the therapy. This information has brought about a reduction in treatment times so as to avoid cell growth that might endanger the treatment result. The radiotherapy that is given today by specialist doctors is safe because the side effects of the treatment are well under control. (orig.)

Aim: This study aimed to determine the prevalence of anaemia and evaluate the relationship of intestinal helminth infection on the anaemia status of children in the rural communities of Evbuomore, Isiohor, and Ekosodin. in the Ovia North East local government area of Edo State, Nigeria. Subjects and Methods : Faecal samples and blood samples were obtained from 316 children aged 1-15 years. Faecal samples were examined using standard parasitological techniques, and anaemia was defined as blood haemoglobin <11 g/dL. Results : Of the 316 children, 38.6% were anaemic: 75.9% of children in Evbuomore, 42.3% in Isiohor and 26.8% in Ekosodin. The overall parasite prevalence in the three communities were: Ascaris lumbricoides (75.6%, hookworm (16.19% and Trichuris trichiura (7.3%. Malnutrition was patent; 37.0% of the children were stunted, 19.3% wasted, and 44.0% underweight. There was a statistically significant association between hookworm and Ascaris lumbricoides infection and anaemia (P < .001. Serum ferritin levels were more sensitive than haemoglobin in detecting anemia and were correlated with intestinal helminth infection. Conclusion : Intestinal helminth infection in a concomitant state of malnutrition is observed in this population. Intervention programmes should be aimed at control of intestinal helminth infection and iron supplementation.

  7. Late bilateral temporal lobe necrosis after conventional radiotherapy. Case report

    International Nuclear Information System (INIS)

    A 63-year-old woman presented with radionecrosis in the bilateral temporal lobes manifesting as dementia about 30 years after undergoing conventional radiotherapy for pituitary adenoma. Computed tomography and magnetic resonance (MR) imaging showed edema and cystic lesions in both temporal lobes. The mass in the left temporal lobe was excised. MR imaging 12 days after surgery showed reduced edema. Her dementia had improved. Radionecrosis usually occurs between several months and a few years after radiotherapy. The incidence of radionecrosis is estimated as 5%, but may be higher with longer follow-up periods. Clinical reports have suggested that larger total doses of radiation are associated with earlier onset of delayed necrosis and the fractional dose is the most significant factor causing cerebral radionecrosis. Radionecrosis can occur long after conventional radiotherapy or stereotactic radiosurgery using a linac-based system or a gamma knife unit. (author)

    Full Text Available Background. Diabetes mellitus characterized by hyperglycaemia presents with various complications amongst which anaemia is common particularly in those with overt nephropathy or renal impairment. The present study has examined the contribution of the hyperglycaemic environment in diabetic rats to the anaemia associated with diabetes mellitus. Method. Sixty male albino rats weighing 175–250 g were selected for this study and divided equally into control and test groups. Hyperglycaemia was induced with 170 kgbwt−1 alloxan intraperitoneally in the test group while control group received sterile normal saline. Blood samples obtained from the control and test rats were assayed for packed cell volume (PCV, haemoglobin (Hb, red blood cell count (RBC, reticulocyte count, glucose, plasma haemoglobin, potassium, and bilirubin. Result. Significant reduction (P<0.01 in PCV (24.40±3.87 versus 40.45±3.93 and haemoglobin (7.81±1.45 versus 13.39±0.40 with significant increase (P<0.01 in reticulocyte count (12.4±1.87 versus 3.69±0.47, plasma haemoglobin (67.50±10.85 versus 34.20±3.83, and potassium (7.04±0.75 versus 4.52±0.63 was obtained in the test while plasma bilirubin showed nonsignificant increase (0.41±0.04 versus 0.24±0.06. Conclusion. The increased plasma haemoglobin and potassium levels indicate an intravascular haemolytic event while the nonsignificant increased bilirubin showed extravascular haemolysis. These play contributory roles in the anaemia associated with diabetes mellitus.

  13. Increased microerythrocyte count in homozygous alpha(+-thalassaemia contributes to protection against severe malarial anaemia.

    Directory of Open Access Journals (Sweden)

    Freya J I Fowkes

    2008-03-01

    Full Text Available BACKGROUND: The heritable haemoglobinopathy alpha(+-thalassaemia is caused by the reduced synthesis of alpha-globin chains that form part of normal adult haemoglobin (Hb. Individuals homozygous for alpha(+-thalassaemia have microcytosis and an increased erythrocyte count. Alpha(+-thalassaemia homozygosity confers considerable protection against severe malaria, including severe malarial anaemia (SMA (Hb concentration 1.1 x 10(12/l as a result of the reduced mean cell Hb in homozygous alpha(+-thalassaemia. In addition, children homozygous for alpha(+-thalassaemia require a 10% greater reduction in erythrocyte count than children of normal genotype (p = 0.02 for Hb concentration to fall to 50 g/l, the cutoff for SMA. We estimated that the haematological profile in children homozygous for alpha(+-thalassaemia reduces the risk of SMA during acute malaria compared to children of normal genotype (relative risk 0.52; 95% confidence interval [CI] 0.24-1.12, p = 0.09. CONCLUSIONS: The increased erythrocyte count and microcytosis in children homozygous for alpha(+-thalassaemia may contribute substantially to their protection against SMA. A lower concentration of Hb per erythrocyte and a larger population of erythrocytes may be a biologically advantageous strategy against the significant reduction in erythrocyte count that occurs during acute infection with the malaria parasite Plasmodium falciparum. This haematological profile may reduce the risk of anaemia by other Plasmodium species, as well as other causes of anaemia. Other host polymorphisms that induce an increased erythrocyte count and microcytosis may confer a similar advantage.

  15. Advice concerning radiotherapy

    International Nuclear Information System (INIS)

    Dutch National cancer incidence figures were calculated by using the reliable data on cancer incidence in the Eindhoven area and population forecasts and information obtained from the Central Bureau of Statistics. Several radiotherapy departments suffer from under capacity (a lack of resources and understaffing). Data have also shown that 35% of cancer patients receive radiotherapy, instead of 50%. Calculations have been made by the committee on the present and future needs with regard to equipment and staff. In 1983, the number of megavoltage therapy units amounted to 38, but should have been 65. It should be 80 in 1990 and 90 in 2000. Since building and installing such equipment is a lengthy process a considerable effort is needed to make up for the arrears. The committee advocates the extension of the system of regional cooperation in cancer care (comprehensive cancer centres), in which radiotherapy departments play a crucial role. Working parties from the committee provided a comprehensive description of current radiotherapy practice with reference to physical, technical, clinical and management aspects. Another working party assessed the results of cancer treatment with regard to many different tumour sites. Recent and expected developments were analysed or indicated. The Radiotherapy Committee commissioned an external team to conduct a project to achieve a picture of future developments using methods different to those of the committee's. An interim advice has been added on this subject. (Auth.)

    Aplastic anaemia (AA) can precede acute lymphoblastic leukaemia (ALL) in 2% of children but this is rarely reported to occur in adults. A 21-year-old male presented with bone marrow failure and bone marrow biopsy showed a profoundly hypocellular marrow. He recovered spontaneously but represented 2 months later when he was diagnosed with pre-B acute lymphoblastic leukaemia. Chromosomal examination revealed 46,XY,del(9)(q13q34). To the best of our knowledge this is the first case to be reported of aplasia preceding ALL with 9q minus as the sole chromosomal abnormality.

    How the Fanconi anaemia (FA) chromosome stability pathway functions to cope with interstrand crosslinks and other DNA lesions has been elusive, even after FANCD1 proved to be BRCA2, a partner of Rad51 in homologous recombination. The identification and characterization of two new Fanconi proteins having helicase motifs, FANCM and FANCJ/BRIP1/BACH1, implicates the FANC nuclear core complex as a participant in recognizing or processing damaged DNA, and the BRIP1 helicase as acting independently of this complex.

    The escalating burden, pathogenesis, and clinical sequel of malaria during pregnancy have combinatorial adverse impact on both mother and foetus that further perplexed the situation of diagnosis, treatment, and prevention. This prompted us to evaluate the status of population at risk of MIP in Hazaribag, Jharkhand, India. Cross-sectional study was conducted over a year at Sadar Hospital, Hazaribag. Malaria was screened using blood smear and/or RDT. Anaemia was defined as haemoglobin concentration. Pretested questionnaires were used to gather sociodemographic, clinical, and obstetrical data. The prevalence of MIP was 5.4% and 4.3% at ANC and DU, and 13.2% malaria was in women without pregnancy. Interestingly, majority were asymptomatically infected with P. vivax (over 85%) at ANC and DU. Peripheral parasitemia was significantly associated with fever within past week, rural origin of subjects, and first/second pregnancies in multivariate analysis, with the highest risk factor associated with fever followed by rural residence. Strikingly in cohort, anaemia was prevalent in 86% at ANC as compared to 72% at DU, whereas severe anaemia was 13.6% and 7.8% at ANC and DU. Even more anaemia prevalence was observed in MIP group (88% and 89% at ANC and DU), whereas severe anaemia was 23% and 21%, respectively. In view of observed impact of anaemia, parasitemia and asymptomatic infection of P. vivax during pregnancy and delivery suggest prompt diagnosis regardless of symptoms and comprehensive drug regime should be offered to pregnant women in association with existing measures in clinical spectrum of MIP, delivery, and its outcome.

    Most uveal melanomas are treated with radiotherapy. An adequate understanding of the effects of radiation on the tumour and the healthy ocular tissues is necessary. Ionizing radiation damages cell membranes, organelles, and DNA. Irradiated cells are lysed or undergo apoptosis, necrosis, and senescence. These effects occur in tumour cells and vascular endothelial cells, resulting in tumour shrinkage, ischaemia, infarction, exudation, and fibrosis, which can cause exudative maculopathy, serous ...

    International Nuclear Information System (INIS)

    Mouth cancer is the sixth most frequent type in the world's population, affecting mostly developing countries. The treatment of choice for this neoplasm is the surgery associated with radiotherapy and / or chemotherapy, which often cause mouth adverse effects. The periodontal reaction to the suffering irradiation morphological and histological alterations decreased the ability of repairing and increased vulnerability to infections. The mouth conditions of the patients who will undergo cancer therapy should be assessed prior to initiation of treatment, mainly to prevent complications.

    Abstract Background Hodgkin's lymphoma (HL) survivors who undergo radiotherapy experience increased risks of second cancers (SC) and cardiac sequelae. To reduce such risks, extended-field radiotherapy (RT) for HL has largely been replaced by involved field radiotherapy (IFRT). While it has generally been assumed that IFRT will reduce SC risks, there are few data that quantify the reduction in dose to normal tissues associated with modern RT practice for patients with mediastinal HL, and no es...

    Cryopreservation of oocytes has been proposed as a way of storing gametes in young patients at high risk of infertility and premature ovarian failure. Recent advances in cryobiology have yielded promising results, leading to oocyte cryopreservation becoming a mainstay of fertility preservation. In this case series, we describe the feasibility of performing ovarian stimulation, and the ethical challenges faced, in teenage girls, aged 14-18 years, prior to undergoing bone marrow transplant for sickle cell anaemia. All eight consecutive cases completed ovarian stimulation and oocyte retrieval with mature oocytes being found and cryopreserved for each patient. The mean dose of gonadotrophin stimulation was 2134.38 IU (95% CI 1593.34-2675.4) and the mean duration of treatment was 11 days (95% CI 10.02-11.98). The mean number of oocytes retrieved was 14.88 (95% CI 7.39-22.36), of which a mean of 12.13 (95% CI 4.72-19.54) oocytes were mature and cryopreserved. There was one case of moderate ovarian hyperstimulation syndrome that required hospital admission for supportive treatment. Oocyte cryopreservation is a technique that can be successfully employed after the retrieval of mature oocytes from the peripubertal ovary, restoring hope to these patients, and their families, of having their own genetic children in the future.

    International Nuclear Information System (INIS)

    Full text: Background: Between 2000 and 2005, at Vidt Medical Center, 85 patients were treated with 3D and IMRT radiotherapy after undergoing radical prostatectomy for localized prostate adenocarcinoma. Objective: To evaluate biochemical recurrence and specific disease free survival and global survival. Materials and method: These patients were divided into two groups: those who engaged in what is called adjuvant therapy (20 patients), who after surgery had increased risk factors and / or persistence of the disease. These risk factors were positive margins, seminal vesicles involvement, capsule infiltration or persistent PSA. The other group were 65 patients referred to as rescue therapy: they were those that presented PSA increase after having undetectable levels as observed nadir after surgery, understanding > 0.2 ng / ml as a high value or palpable nodule on rectal touch with or without positive biopsy. Follow up was between 24 and 84 months, the dose delivered was between 6500 - 7000 cGy. Also evaluated the early and late toxicity, urinary and rectal, according to RTOG criteria. Conclusion: The results obtained confirm the benefits of postoperative radiation therapy for both groups of patients, showing a more favorable trend on those treated with adjuvant therapy. (authors)

  10. Chemical modifiers of radiotherapy

    International Nuclear Information System (INIS)

    Only two groups, anticancer drugs and radiosensitizers are discussed among many groups of chemical modifiers. In combined radiotherapy (RT) with chemotherapy (CT), sequential administration seems to be superior to concomitant administration, because simultaneous use enhances intensively normal tissue damage. In sequential administration, interruption of CT during RT causes growth of distant metastases. So, alternating scheme of RT and CT is proposed and evaluated clinically. Hypoxic cell sensitizers including well-known misonidazole and PLDR inhibitors (Ara-A etc.) are promising in radiotherapy. They should be used intermittently two or three times during RT in order to avoid neurotoxicity of misonidazole. (author) 70 refs

    Full Text Available David Alimi Department of Anesthesiology, University of Pittsburgh Medical Center, Pittsburgh, PA, USAWe read with great interest the excellent review on xerostomia induced by radiotherapy, by Pinna et al.1 The authors should be congratulated for a very detailed review of the physiopathology, clinical symptoms, and therapeutic management of an extremely difficult condition. Although we agree that the use of anticholinergic medication represents treatment, it requires the patient to have residual salivary gland function. Unfortunately, it is well established that in most cases radiotherapy destroys most of the salivary gland and associated salivary secretions.

    Full Text Available Background. Sickle cell disorders are known to have a negative effect on linear growth. This could potentially affect proportional growth and, hence, Cormic Index. Objective. To determine the Cormic Index in the sickle cell anaemia population in Lagos. Methodology. A consecutive sample of 100 children with haemoglobin genotype SS, aged eight months to 15 years, and 100 age and sex matched controls (haemoglobin genotype AA was studied. Sitting height (upper segment and full length or height were measured. Sitting height was then expressed as a percentage of full length/height (Cormic Index. Results. The mean Cormic Index decreased with age among primary subjects (SS and AA controls. The overall mean Cormic Index among primary subjects was comparable to that of controls (55.0±4.6% versus 54.5±5.2%; 54.8±4.5% versus 53.6±4.9% in boys and girls, respectively. In comparison with AA controls, female children with sickle cell anaemia who were older than 10 years had a significantly lower mean Cormic Index. Conclusion. There was a significant negative relationship between Cormic Index and height in subjects and controls irrespective of gender. Similarly, a significant negative correlation existed between age, sitting height, subischial leg length, weight, and Cormic Index in both subjects and controls.

  13. The role of host nutrition in the pathogensis of liver fluke anaemia

    International Nuclear Information System (INIS)

    Although it is widely accepted that the course of many helminth diseases of sheep is determined by two main variables, namely the level of infection and the host's nutritional status, the importance of the latter in the pathogenesis of ovine fascioliasis remains to be determined. The results of the experiment described here demonstrate that dietary quality has no significant effect upon fluke establishment but profoundly influences the severity of the disease as evidenced by the more rapid development of anaemia and by earlier mortalities among sheep restricted to a maintenance ration (containing about 6% crude protein) compared with similarly infected animals receiving a diet commensurate with growth (13% crude protein). Concurrent measurements of blood volume and of red cell turnover using radioisotopic methods revealed that in all animals the anaemia was caused by a combination of haemodilution, intra-hepatic and biliary haemorrhage, but that the earlier and more severe disturbances in protein-restricted sheep reflected the earlier development of these changes in association with a faster rate of fluke migration, and was ultimately complicated by impaired erythropoiesis arising from iron deficiency.

  14. The Fanconi anaemia pathway orchestrates incisions at sites of crosslinked DNA.

    Science.gov (United States)

    Crossan, Gerry P; Patel, Ketan J

    2012-01-01

    Fanconi anaemia (FA) is a rare, autosomal recessive, genetically complex, DNA repair deficiency syndrome in man. Patients with FA exhibit a heterogeneous spectrum of clinical features. The most significant and consistent phenotypic characteristics are stem cell loss, causing progressive bone marrow failure and sterility, diverse developmental abnormalities and a profound predisposition to neoplasia. To date, 15 genes have been identified, biallelic disruption of any one of which results in this clinically defined syndrome. It is now apparent that all 15 gene products act in a common process to maintain genome stability. At the molecular level, a fundamental defect in DNA repair underlies this complex phenotype. Cells derived from FA patients spontaneously accumulate broken chromosomes and exhibit a marked sensitivity to DNA-damaging chemotherapeutic agents. Despite complementation analysis defining many components of the FA DNA repair pathway, no direct link to DNA metabolism was established until recently. First, it is now evident that the FA pathway is required to make incisions at the site of damaged DNA. Second, a specific component of the FA pathway has been identified that regulates nucleases previously implicated in DNA interstrand crosslink repair. Taken together, these data provide genetic and biochemical evidence that the FA pathway is a bona fide DNA repair pathway that directly mediates DNA repair transactions, thereby elucidating the specific molecular defect in human Fanconi anaemia.

  15. Marrow uptake index (MUI): A quantitative scintigraphic study of bone marrow in aplastic anaemia

    International Nuclear Information System (INIS)

    Aplastic anaemia affects the entire bone marrow. This prospective study was undertaken to develop and standardise a new nuclear medicine technique called 'dynamic bone marrow imaging'. Eleven patients and ten controls were studied. Serial images of the pelvis were obtained in frame mode following intravenous injection of 185-370 mBq of 99mTc S. Colloid, and an index, called the bone marrow uptake index was calculated by taking into consideration the time activity curve obtained over the iliac crest. This was followed by static imaging of the entire bone marrow in all cases. It was possible to obtain excellent information regarding topographic distribution of bone marrow as well as detect early changes in bone marrow function following treatment. An attempt was also made to correlate bone marrow cellularity as obtained by bone marrow biopsy with results of dynamic bone marrow scintigraphy. On the basis of the encouraging results obtained in the present study, the authors feel that dynamic bone marrow imaging is an excellent technique for the objective evaluation of bone marrow in aplastic anaemia. 20 refs.; 4 figs.; 5 tabs

    Kuliszkiewicz-Janus, Małgorzata; Zimny, Anna

    2003-11-01

    Glucose-6-phosphate dehydrogenase (G6PD) is one of the most important cytoprotective enzymes for oxidative stress. The WHO classification of G6PD deficiency, based on enzyme activity and clinical significance, distinguishes five variants. Chronic haemolytic process is rare and the main factors causing haemolysis are: infections, substances derived from plants, drugs with high oxidation-reduction potential, stress, ketoacidosis in diabetes and surgery operations. We report two cases of women belonging to the class 3 of the WHO classification in whom haemolysis occured during pregnancy. One of the patients developed two incidents of haemolytic anaemia. The cause of the first episode, nine months before pregnancy, was probably infection of the urinary tract caused by Escherichia coli, but the influence of the drugs also cannot be excluded. Because of the genetic background of this enzymopathy we also examined members of the patients, families but did not find any evidence of G6PD deficiency among them. The reported cases indicate that haemolytic anaemia caused by G6PD deficiency may occur during pregnancy what can lead to many not only haematological but also serious obstetrical complications such as infertility, fetus malformations and even its death. We also draw attention to several difficulties in diagnosing G6PD deficiency especially during haemolysis. PMID:16737003

    Drug-induced immune haemolytic anaemia is a rare but serious condition. This study investigated the possibility of drug aetiology of immune haemolytic anaemia (IHA) in 134 patients with new onset of IHA who were identified in the Berlin Case-Control Surveillance Study between 2000 and 2009. Single drugs related to IHA in three or more patients and assessed more than once as a certain or probable cause of IHA in a standardized causality assessment included diclofenac, fludarabine, oxaliplatin, ceftriaxone and piperacillin. In a case-control study including all 124 IHA cases developed in outpatient care and 731 controls, significantly increased odds ratios (OR) were observed for beta-lactam antibiotics (OR=8·8; 95% confidence interval [CI] 3·2-25·2), cotrimoxazole (OR=6·5; CI 1·1-37·9), ciprofloxacin (OR=6·9, CI 1·3-38·5), fludarabine (OR=22·2; CI: 2·8-454·5) and lorazepam (OR=5·3; CI: 1·2-21·2). Excluding new onset cases with a chronic IHA disease course, an increased risk became also apparent for diclofenac with an OR of 3·1 (CI 1·3-7·0). This is the first case-control study investigating drugs as risk factors for IHA. It corroborates an increased risk for several drugs that have been implicated as a cause of IHA in the standardized causality assessment of individual cases. PMID:21749359

  18. Cloning, expression and preliminary crystallographic analysis of the equine infectious anaemia virus (EIAV) gp45 ectodomain

    International Nuclear Information System (INIS)

    The equine infectious anaemia virus gp45 ectodomain was cloned, expressed and crystallized. Preliminary crystallographic analysis showed that the protein belonged to space group P63 and contained one molecule per asymmetric unit. Like human immunodeficiency virus (HIV), equine infectious anaemia virus (EIAV) belongs to the lentivirus genus. The first successful lentiviral vaccine was developed for EIAV. Thus, EIAV may serve as a valuable model for HIV vaccine research. EIAV glycoprotein 45 (gp45) plays a similar role to gp41 in HIV by mediating virus–host membrane fusion. The gp45 ectodomain was constructed according to the structure of HIV gp41, with removal of the disulfide-bond loop region. The protein was expressed in Escherichia coli and crystallized following purification. However, most of the crystals grew as aggregates and could not be used for data collection. By extensively screening hundreds of crystals, a 2.7 Å resolution data set was collected from a single crystal. The crystal belonged to space group P63, with unit-cell parameters a = b = 46.84, c = 101.61 Å, α = β = 90, γ = 120°. Molecular replacement was performed using the coordinates of various lengths of HIV gp41 as search models. A long bent helix was identified and a well defined electron-density map around the long helix was obtained. This primary model provided the starting point for further refinement

    Full Text Available At present lung tumor radiation therapy has entered the accurate radiotherapy era. Precise radiotherapy includes intensity modulated radiotherapy (IMRT, image-guided radiotherapy (IGRT and stereotactic body radiotherapy (SBRT. During the process of implementing precise radiotherapy, these problems should be fully considered to ensure executing precise radiotherapy accurately: patient positioning, controlling of the lung tumor motion, selecting of image techniques, PTV margin, dose prescription and reporting, arrangement of beams, controlling of dose volume and treatment delivering.

    Full Text Available A recently published paper addressed the interesting topic of prevention of erectile dysfunction (ED with tadalafil, a phosphodiesterase-type 5 inhibitor (PDE5i in patients undergoing radiation therapy for localized prostate cancer. [1] Tadalafil 5 mg or placebo was administered once-daily for 24 weeks in patients undergoing external-beam radiotherapy (EBRT or brachytherapy (BT for prostate cancer. This randomized trial did not show superior efficacy of the active drug compared with placebo 4-6 weeks after stopping the study drug. Furthermore, patients younger than 65 years did not respond significantly better than older patients.

  1. Utility of an Australasian registry for children undergoing radiation treatment

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the utility of an Australasian registry ('the Registry') for children undergoing radiation treatment (RT). Children under the age of 16years who received a course of radiation between January 1997 and December 2010 and were enrolled on the Registry form the subjects of this study. A total of 2232 courses of RT were delivered, predominantly with radical intent (87%). Registrations fluctuated over time, but around one-half of children diagnosed with cancer undergo a course of RT. The most prevalent age range at time of RT was 10–15years, and the most common diagnoses were central nervous system tumours (34%) and acute lymphoblastic leukaemia (20%). The Registry provides a reflection of the patterns of care of children undergoing RT in Australia and a mechanism for determining the resources necessary to manage children by RT (human, facilities and emerging technologies, such as proton therapy). It lacks the detail to provide information on radiotherapy quality and disease outcomes which should be the subject of separate audit studies. The utility of the Registry has been hampered by its voluntary nature and varying needs for consent. Completion of registry forms is a logical requirement for inclusion in the definition of a subspecialist in paediatric radiation oncology.

  2. Quality indicators in radiotherapy

    International Nuclear Information System (INIS)

    Background and purpose: There is a widespread and increasing tendency to develop hospital performance indicators in the field of accreditation/certification systems and quality benchmarking. A study has been undertaken to develop a set of performance indicators for a typical radiotherapy Centre and to evaluate their ability to provide a continuous quality improvement. Materials and methods: A working group consisting of radiation oncologists, medical physicists and radiation technologists under the coordination of experts in health technology assessment has elaborated a set of general indicators able to monitor performances and the quality level of a typical radiotherapy Centre. The work has been carried out through four steps: a preliminary set of indicators was selected; data on these indicators were collected in a number of Italian radiotherapy Centres and medical physics Services; problems in collection and analysis of data were discussed; a final set of indicators was developed. Results: A final set of 13 indicators is here presented. They concern general structural and/or operational features, health physics activities and accuracy and technical complexity of the treatment. Conclusions: The indicators tested in a few Italian Centres of radiotherapy and medical physics Services are now ready to be utilized by a larger community

  3. Bowel disease after radiotherapy

    International Nuclear Information System (INIS)

    The clinical presentation, operative findings and outcome in 40 patients who required surgery for bowel disease after radiotherapy are presented. The type of presentation varied according to the time after radiotherapy. In the first month, many patients had a proctitis but none required surgery. Five patients were operated on within one month, 2 for radiation-induced acute ileitis and 3 for exacerbations of pre-existing disease (diverticular disease 2, ulcerative colitis 1). The commonest time of presentation was between 3 and 18 months after radiotherapy, when 20 patients needed surgery for bowel disease caused by radiation-induced local ischaemia. Twelve of these patients had chronic perforation, 6 had severe rectal bleeding and 2 had painful anorectal ulceration. Fifteen patients presented between 2 and 24 years after radiotherapy, usually with incomplete intestinal obstruction due to a fibrous stricture, but 2 patients had rectal carcinoma. Wide resection of the involved bowel was the principal method of treatment but any anastomosis was protected by a proximal defunctioning stoma. There was no operative mortality but 10 patients have died subsequently. The danger of dismissing these patients as having incurable malignancy is stressed because, although the condition is infrequent, it is usually amenable to adequate surgery. (author)

  6. Quality assurance in radiotherapy

    International Nuclear Information System (INIS)

    Good radiotherapy results and safety of treatment require the radiation to be optimally applied to a specified target area and the correct dose. According to international recommendations, the average uncertainty in therapeutic dose should not exceed 5%. The need for high precision in therapeutic dose requires quality assurance covering the entire radiotherapy process. Besides the physical and technical characteristics of the therapy equipment, quality assurance must include all radiotherapy equipment and procedures that are significant for the correct magnitude and precision of application of the therapeutic dose. The duties and responsibilities pertaining to various stages of treatment must also be precisely defined. These requirements may be best implemented through a quality system. The general requirements for supervision and quality assurance of medical radiation apparatus are prescribed in section 40 of the Radiation Act (592/1991, amendment 1142/1998) and in sections 18 and 32 of the Decree of the Ministry of Social Affairs and Health on the medical use of radiation (423/2000). Guide ST 2.2 imposes requirements on structural radiation shielding of radiotherapy equipment and the premises in which it is used, and on warning and safety arrangements. Guide ST 1.1 sets out the general safety principles for radiation practices and regulatory control procedure for the use of radiation. Guide ST 1.6 provides general requirements for operational measures in the use of radiation. This Guide sets out the duties of responsible parties (the party running a radiation practice) in respect of arranging and maintaining radiotherapy quality assurance. The principles set out in this Guide and Guide ST 6.3 may be applied to radionuclide therapy

  7. Dietary Intake of Iron Rich Food and Awareness on Iron Deficiency Anaemia among Female Students in Rawalpindi

    International Nuclear Information System (INIS)

    Objective: To assess the awareness and intake of iron rich diet amongst college girls with a particular focus on the knowledge about the iron deficiency anaemia. Materials and Methods: A cross sectional survey was conducted in Government College for Women Rawalpindi, during September - December 2010. One hundred and thirty five students of intermediate level aged 17-19 years were selected through convenient sampling technique. The sample size was calculated by WHO-sample size calculator, keeping 95 percent Cl, p<0.05 statistically significant, anticipated population proportion of iron deficiency anaemia 35 percent and absolute precision at 0.08. Results: The awareness about iron rich diet and iron deficiency anaemia was satisfactory (86 percent), while poor intake of iron rich diet amongst adolescent college girls (52 percent) was found. About 65 percent of the participants had knowledge about the causes of iron deficiency anaemia (IDA); while 72 percent and 80 percent knew about the prevention and treatment of IDA respectively. Conclusions: Results indicate the gap between knowledge and practices about IDA; it highlights the need of an effective health promotional programme to raise awareness about the significance of iron in young female diet and to highlight the consequences when it is absent.

    2000-12-01

    A prospective study, aimed to investigate the aetiology of an unusual clustering of cases of severe acute haemolytic anaemia affecting a high percentage of the adult population, was carried out in two isolated Yanomamo communities of the Upper Orinoco basin in Venezuela. Twenty-six patients with active or recent episodes of severe haemolysis were evaluated. All of them exhibited massive liver and spleen enlargement and fulfilled the diagnostic criteria of the hyperreactive malarious splenomegaly (HMS) syndrome. In four cases with advanced non-alcohol-related chronic liver disease, hypersplenism, severe haemolytic anaemia and acanthocytosis, the characteristic clinical and laboratory findings of spur cell anaemia were documented. Chronic infection by the HBV and HCV was present in three of them. However, in most of the 22 additional HMS cases, the acute haemolytic condition appeared associated with the occurrence of a cold agglutinin-mediated autoimmune response. The clustering of a significant number of cases of severe acute haemolysis in HMS patients from this small isolated aboriginal community is most unusual, and represents a serious complicating factor for a population already beleaguered by a high prevalence of malaria due to multiresistant strains of Plasmodium falciparum. Moreover, the coexistence of HMS and severe chronic HBV or HCV infection may further aggravate the course of the haemolytic disorder, because of the occurrence of spur cell anaemia. PMID:11114387

    A 38-day-old male warthog (Phacochoerus aethiopicus) with marked anaemia (haematocrit = 14 %) presented to the Denver Zoological Gardens hospital with ataxia, tachypnoea, suspected stunted growth and cardiomegaly. The piglet demonstrated some features consistent with both iron deficiency anaemia and autoimmune haemolytic anaemia. Serum-soluble iron was below the level of detection (< 8.96 micromol/l). Iron deficiency anaemia is a well recognised entity in domestic swine reared on concrete and denied access to soil. Fifteen captive warthogs were subsequently evaluated for serum soluble iron content (mean = 21.62 +/- 4.36 micromol/l as well as 5 neonatal warthog piglets that required hand-rearing. Only 1 of 5 neonatal warthog piglets had measurable serum soluble iron (9.50 micromol/l). These data suggest that warthogs are similar to domestic swine and are born with low iron stores. Some form of iron supplementation should be considered for captive neonatal warthog piglets, especially if they are reared on concrete. PMID:12515305

  19. A 3-marker index improves the identification of iron disorders in CKD anaemia.

    Directory of Open Access Journals (Sweden)

    Lucile Mercadal

    Full Text Available BACKGROUND: Iron disorders are common and complex in chronic kidney disease (CKD. We sought to determine whether a 3-marker index would improve the classification of iron disorders in CKD anaemia. METHODS: We studied the association between Hb level and iron indexes combining 2 or 3 of the following markers: serum ferritin (<40 ng/mL, transferrin saturation (TSAT<20% and total iron binding capacity (TIBC<50 µmol/L in 1011 outpatients with non-dialysis CKD participating in the Nephrotest study. All had glomerular filtration rates measured (mGFR by (51Cr-EDTA renal clearance; 199 also had hepcidin measures. RESULTS: The TSAT-TIBC-ferritin index explained Hb variation better than indexes combining TSAT-TIBC or ferritin-TSAT. It showed hypotransferrinaemia and non-inflammatory functional iron deficiency (ID to be more common than either absolute or inflammatory ID: 20%, 19%, 6%, and 2%, respectively. Hb was lower in all abnormal, compared with normal, iron profiles, and decreased more when mGFR was below 30 mL/min/1.73 m(2 (interaction p<0.0001. In patients with mGFR<30 mL/min/1.73 m(2, the Hb decreases associated with hypotransferrinaemia, non-inflammatory functional ID, and absolute ID were 0.83±0.16 g/dL, 0.51±0.18 and 0.89±0.29, respectively. Compared with normal iron profiles, hepcidin was severely depressed in absolute ID but higher in hypotransferrinaemia. CONCLUSIONS: The combined TSAT-TIBC-ferritin index identifies hypotransferrinaemia and non-inflammatory functional ID as the major mechanisms of iron disorders in CKD anaemia. Both disorders were associated with a greater decrease in Hb when mGFR was <30 mL/min/1.73 m(2. Taking these iron profiles into account may be useful in stratifying patients in clinical trials of CKD anaemia and might improve the management of iron therapy.

  1. Non-invasive anesthesia for children undergoing proton radiation therapy

    International Nuclear Information System (INIS)

    Background: Proton therapy is a newer modality of radiotherapy during which anesthesiologists face specific challenges related to the setup and duration of treatment sessions. Purpose: Describe our anesthesia practice for children treated in a standalone proton therapy center, and report on complications encountered during anesthesia. Materials and methods: A retrospective review of anesthetic records for patients ⩽18 years of age treated with proton therapy at our institution between January 2006 and April 2013 was performed. Results: A total of 9328 anesthetics were administered to 340 children with a median age of 3.6 years (range, 0.4–14.2). The median daily anesthesia time was 47 min (range, 15–79). The average time between start of anesthesia to the start of radiotherapy was 7.2 min (range, 1–83 min). All patients received Total Intravenous Anesthesia (TIVA) with spontaneous ventilation, with 96.7% receiving supplemental oxygen by non-invasive methods. None required daily endotracheal intubation. Two episodes of bradycardia, and one episode each of; seizure, laryngospasm and bronchospasm were identified for a cumulative incidence of 0.05%. Conclusions: In this large series of children undergoing proton therapy at a freestanding center, TIVA without daily endotracheal intubation provided a safe, efficient, and less invasive option of anesthetic care

  2. External audit in radiotherapy dosimetry

    International Nuclear Information System (INIS)

    Quality audit forms an essential part of any comprehensive quality assurance programme. This is true in radiotherapy generally and in specific areas such as radiotherapy dosimetry. Quality audit can independently test the effectiveness of the quality system and in so doing can identify problem areas and minimize their possible consequences. Some general points concerning quality audit applied to radiotherapy are followed by specific discussion of its practical role in radiotherapy dosimetry, following its evolution from dosimetric intercomparison exercises to routine measurement-based on-going audit in the various developing audit networks both in the UK and internationally. Specific examples of methods and results are given from some of these, including the Scottish+ audit group. Quality audit in radiotherapy dosimetry is now well proven and participation by individual centres is strongly recommended. Similar audit approaches are to be encouraged in other areas of the radiotherapy process. (author)

    The findings about the regular, spontaneous and complete regression of cavernous skin hemangiomas occurring in infants and those findings about the damaging effects due to ionising radiation - here particularly local growth disturbances - led to the development of very cautious diagnostic methods and to a considerate individual dosage and radiotherapy, which always takes into consideration the spontaneous regression tendency of the hemangiomas. However, a function-impairing localisation at the orifices, fulminant macrosomia, tendency to hemorrhages and poly-infection with superficial ulceration and even thrombopenic syndromes of the Kasabach-Merritt type may become necessary, urgent and also vital indications for a particular radiotherapy. For the sake of the patients, irradiation methods, which do not provoke any risk of radiation hazards, have to be preserved and applied in practice. Certainly further research and the nosologic nature of hemangiomas is required. A general non-treatment of hemangiomas is refused.

  4. Nutrition and radiotherapy

    International Nuclear Information System (INIS)

    Full text: Radiation is a common method of treating large tumours, however one of the major problems in radiation therapy is the severe side effects that may limit its efficacy. Utilising nutrients can assist in the control of these side effects which will greatly enhance the quality of life of the patient plus improve the effectiveness of the radiation. Another controversial point regarding radiation and nutrition is the concurrent use of antioxidants and radiotherapy. The science literature is in agreement that supplementing with antioxidants after radiation is essential. In addition, most studies now show that antioxidants do not interfere with the efficacy of radiotherapy. These issues and suggestions for nutrients to assist during and after radiation will be discussed

    The neurological condition triggered by anaesthesia with nitrous oxide involves the cyanocobalamine pathway and is characterised by progressive demyelination and axonal lesions of the peripheral nerves and cervicothoracic spinal cord (posterior and anterolateral columns) giving a peripheral neuropathy and very frequently subacute combined degeneration of the spinal cord. It is possible to show these demyelinating lesions by MRI of the spine, allowing early diagnosis and follow-up. We describe a case of myeloneuropathy with onset a few hours after nitrous oxide anaesthesia in a patient with macrocytic anaemia and possible subclinical vitamin B{sub 12} deficiency and MRI evidence of a lesion of the cervical spinal cord. Neurological and haematological improvement followed cyanocobalamine replacement. (orig.) With 2 figs., 15 refs.

  7. Radiation protection of the patient radiotherapy

    International Nuclear Information System (INIS)

    Systematic studies of gonadal doses to patients undergoing therapy on 60Co and X-ray machines were carried out using thermoluminescence dosimeters (TLD). Phantom and in vivo measurements were performed for various field sizes and for different positions of the centre of the field on the patient's body with the exception of fields including the gonads during radiotherapeutic treatment. It was shown that there is no effect of various SSD and that most radiation reaching gonads is transmitted axially through the body and therefore, it is impossible to reduce this dose with a simple shielding. The figures presented allow prediction of gonadal doses at various conditions. The efficiency of lung, mouth etc. shielding during radiotherapy was also investigated. (orig.)

  8. Radiotherapy for aggressive fibromatosis

    International Nuclear Information System (INIS)

    Purpose/Objective: To evaluate local control with radiotherapy for aggressive fibromatosis. Materials and Methods: Fifty-three patients with histologically confirmed aggressive fibromatosis were treated with radiotherapy at the University of Florida between March 1975 and June 1992. The minimum length of follow-up was 2 years; 88% of patients had follow-up for at least 5 years. Thirty-nine patients had lesions in an extremity and 14 patients had lesions in the trunk. Twenty-nine patients were treated for gross disease. Patients were treated with total doses between 35 Gy and 70 Gy; 83% of patients received 50 Gy to 60 Gy. Results: Local control was achieved in 23 of 29 patients (79%) treated for postoperative microscopic residual disease. Local control was achieved in 21 of 24 patients (88%) treated for gross disease; gross disease was controlled in 8 of 8 patients with previously untreated lesions, and in 13 of 16 patients treated for postoperative gross residual and recurrent disease. Overall, aggressive fibromatosis was locally controlled in 83% of treated patients. All 9 treatment failures occurred with extremity lesions 4 to 68 months after initiation of treatment. Of the 9 recurrences, 4 were out-of-field, 3 were in-field, and 4 occurred at the margin of the irradiated field. Salvage was successful in 8 of 9 patients in whom salvage was attempted with surgery alone or combined with postoperative radiotherapy. A functional limb was maintained in 38 of 39 patients with extremity or limb girdle lesions. The most serious complication of treatment was pathologic fracture, which occurred in 3 of 53 treated patients; all 3 fractures healed with conservative management. Conclusion: Radiotherapy is a valuable adjunct to surgery in the management of aggressive fibromatosis and can be used alone in patients with unresectable or inoperable disease

  9. Conformal radiotherapy: a glossary

    International Nuclear Information System (INIS)

    Most of the concepts and terms related to conformal radiotherapy were produced by English-speaking authors and eventually validated by international groups of experts, whose working language was also English. Therefore, a significant part of this literature is poorly accessible to the French-speaking radiation oncology community. The present paper gathers the 'official' definitions already published in French, along with propositions for the remaining terms which should be submitted to a more formal and representative validation process.

    Full Text Available Background: Abnormal lipid homeostasis has been reported in sickle cell anaemia (SCA as well as in other haematological disorders. However, there is little information on the lipid profile of SCA subjects in vaso-occlusive crisis (VOC. This study determined the lipid profile of adult SCA subjects in VOC and in steady state (SSCA. Materials and Methods: Fifty-eight (58 adults with HbSS (30 in steady state and 28 in vaso-occlusive crisis and 24 age-matched healthy individuals with HbAA genotype were recruited into this study. Standard methods were used for the determination of blood pressure (BP, packed cell volume (PCV, total white blood cell count (WBC and haemoglobin phenotype. After an overnight fast, 5 ml of venous blood was obtained from each SSCA and the controls while samples were collected upon admission in the VOC group. Plasma lipid profile was determined using enzymatic method. Differences between two groups were determined using independent Student′s t-test or Man-Whitney U as appropriate. P-values less than 0.05 were considered significant. Results: Plasma total cholesterol (TC and high density lipoprotein (HDL were significantly lower while the ratio of triglyceride (TG to HDL (TG/HDL was significantly higher in SSCA compared with the controls. Low density lipoprotein (LDL and TC were significantly lower in SCA subjects in VOC compared with controls. However, TC, TG, LDL and TG/HDL were significantly lower while HDL was significantly higher in VOC compared with SSCA. Conclusion: Sickle cell anaemia subjects have defective fasting lipid metabolism which becomes pronounced with VOC.

    AIM: Anaemia caused by acute upper gastrointestinal bleeding is treated with blood transfusion or iron, but patients usually face a two-month recovery period from posthaemorrhage anaemia. This prospective, randomised, open,pilot study was designed to investigate whether recombinant human erythropoietin (Epoetin) therapy accelerate haematocrit increase in the post-bleeding recovery period.METHODS: We studied hospitalised patients admitted because of acute ulcer bleeding or haemorrhagic gastritis,who had a haematocrit of 27-33% and did not receive blood transfusions. One day after the endoscopic confirmation of cessation of bleeding, they were randomised either to erythropoietin (20 000 IU Epoetin alfa subcutaneously, on days 0, 4 and 6) plus iron (100 mg im, on days 1- 6, (G1) or iron only (G2). Haematocrit was measured on days 0, 6, 14,30, 45, and 60, respectively.RESULTS: One patient from G1 and two from G2 were lost to follow-up. Therefore, 14 and 13 patients from G1 and G2respectively were analysed. Demographic characteristics, serum iron, ferritin, total iron binding capacity, reticulocytes, and haematocrit were not significantly different at entry to the study.Median reticulocyte counts were significantly different between groups on day six (G1: 4.0, 3.0-6.4 vsG2: 3.5, 2.1-4.4%,P=0.03) and median haematocrit on day fourteen [G1: 35.9,30.7-41.0 vsG2: 32.5, 29.5-37.0% (median, range), P=0.04].CONCLUSION: Erythropoietin administration significantly accelerates correction of anemia after acute ulcer bleeding.The haematocrit gain is equivalent to one unit of transfused blood two weeks after the bleeding episode.

    Vitamin B(12) stores at birth are adequate for infants until the end of the first year of life even if it 's concentration in maternal breast milk is low. However, there are some situations in which infants have depleted vitamin B(12) stores and in addition have a low dietary intake of cobalamin. Vitamin B(12) depletion occurs in infants who are exclusively breastfed by mothers who have unrecognized pernicious anemia or are strict vegetarians for many years. In those infants symptoms of bone marrow disfunction and impaired development of the central nervous system appear already in the first months of life. Unrecognized cobalamin deficiency may lead to serious neurologic consequences, and even to the death of the child. The authors present a case of a 7.5 month old girl admitted to the Department of Paediatrics, Haematology, Oncology and Endocrinology. Gdańsk Medical University suspected of acute leukaemia. Based on a detailed diagnostic procedure a final diagnosis of vitamin B(12) deficiency anaemia was established. The child was exclusively breast-fed. Results of investigations into the reason for cobalamin deficiency in the patient s organism. Led to the diagnosis of pernicious anaemia in the mother. Such a suspicion had been made during pregnancy, but no continuation of investigations nor appropriate treatment were implemented. After treatment with vitamin B(12) supplements and modification of the diet the patient improved quickly and remarkably. A few months follow-up was enough to observe remarkable improvement of psychomotor development of this child. PMID:15738604

    Full Text Available Objectives. Sickle cell anaemia (SCA is one of the commonest genetic disorders in the world. It is characterized by anaemia, periodic attacks of thrombotic pain, and chronic systemic organ damage. Recent studies have suggested that individuals with SCA especially from developing countries are more likely to be iron deficient rather than have iron overload. The study aims to determine the iron status of SCA patients in Ilorin, Nigeria. Methods. A cross-sectional study of 45 SCA patients in steady state and 45 non-SCA controls was undertaken. FBC, blood film, sFC, sTfR, and sTfR/log sFC index were done on all subjects. Results. The mean patients’ serum ferritin (589.33 ± 427.61 ng/mL was significantly higher than the mean serum ferritin of the controls (184.53 ± 119.74 ng/mL. The mean serum transferrin receptor of the patients (4.24 ± 0.17 μg/mL was higher than that of the controls (3.96 ± 0.17 μg/mL (p=0.290. The mean serum transferrin receptor (sTfR/log serum ferritin index of the patients (1.65 ± 0.27 μg/mL was significantly lower than that of the control (1.82 ± 0.18 μg/mL (p=0.031. Conclusion. Iron deficiency is uncommon in SCA patients and periodic monitoring of the haematological, biochemical, and clinical features for iron status in SCA patients is advised.

    Full Text Available Background: Sickle cell anaemia (SCA remains associated with high risks of morbidity and early death. Children with SCA are at high risk for ischaemic stroke and transient ischaemic attacks, secondary to intracranial arteriopathy involving carotid and cerebral arteries. Allogeneic haematopoietic stem cell transplantation (HSCT is the only curative treatment for SCA. We report our experience with transplantation in a group of patients with the Black African variant of SCA. Patients and Methods: This study included 31 consecutive SCA patients who underwent bone marrow transplantation from human leukocyte antigen (HLA-identical sibling donors between 2010 and 2014 following a myeloablative-conditioning regimen. Results: The median patient age was 10 years (range 2-17 years. Before transplantation, 14 patients had recurrent, painful, vaso-occlusive crisis; ten patients had recurrent painful crisis in association with acute chest syndrome; three patients experienced ischaemic stroke and recurrent vaso-occlusive crisis; two patients experienced ischaemic stroke; one patient exhibited leukocytosis; and one patient exhibited priapism. Of the 31 patients, 28 survived without sickle cell disease, with Lansky/Karnofsky scores of 100. All surviving patients remained free of any SCA-related events after transplantation. Conclusion: The protocols used for the preparation to the transplant in thalassaemia are very effective also in the other severe haemoglobinopathy as in the sickle cell anaemia with 90% disease free survival. Today, if a SCA patient has a HLA identical family member, the cellular gene therapy through the transplantation of the allogeneic haemopoietic cell should be performed. Tomorrow, hopefully, the autologous genetically corrected stem cell will break down the wall of the immunological incompatibility.

  17. Parenteral iron sucrose in iron deficiency anaemia of paediatric chronic kidney disease

    International Nuclear Information System (INIS)

    Background: Erythropoietin (Epo) and iron therapy plays a major role in the management of renal anaemia. Iron sucrose (IS) has been used to treat iron deficiency anaemia (IDA) and to maintain adequate iron store in chronic kidney disease (CKD). The objective of the study was to determine the response and safety of IS in the treatment of IDA. Methods: This retrospective study was carried out in the Department of Nephrology, National Institute of Child Health, Karachi from Dec 2008 to Dec 2010. Children aged 6 months to 14 years, CKD-stage 2-5, and IDA were included. Pertinent data including age, gender, serum creatinine (SCr), CKD-stage, aetiology, treatment mode, IS dose, pre- and post-treatment parameters and side effects were collected and analysed. Results: Among 35, majority (66%) were boys. Mean age was 6.97+-4.13 years and mean SCr was 3.78+-3.1 mg/dl. Majority were in CKD-stage 4-5 and treated conservatively. Major aetiologies were hypoplasia-dysplasia (40%), juvenile nephronophthiasis (17.14%), posterior urethral valves, and stones. Baseline mean Hb and Transferrin Saturation (TS) was 7.38+-1.38 g/dl and 11.19+-5.28% respectively. Mean Hb increased to 9.22+-16.32 g/dl with correction of iron deficit (p<0.001) and a sustained rise in Hb was observed after Epo and maintenance iron sucrose. Mean TS% increased to 49.13+-18% (p<0.001). No major side effects were observed except iron overload. Conclusion: Iron sucrose was effective in improving IDA in CKD without significant side effects. Iron sucrose may be used to treat IDA with monitoring for iron overload. (author)

  18. Photoscanning of the Spleen Using Heat-Treated Cr51-Labelled Erythrocytes in Congenital Haemolytic Anaemias

    International Nuclear Information System (INIS)

    The delineation of the spleen by photoscanning after the intravenous injection of heat-treated Cr51-labelled erythrocytes is valuable when investigating congenital haemolytic anaemias, especially thalassaemia, a disease which is recognized as one of the most important public health problems in Greece. Heat-treated Cr51-labelled erythrocytes were prepared as follows: blood was taken from the subject by venepuncture and delivered into a sterile bottle containing acid-citrate-dextrose. The red cells were separated by centrifugation and the plasma discarded. 50 - 150 μc Cr51-chromate was added to the red cells and the mixture allowed to stand for 30 min at room temperature. The labelled cells were washed once with saline and re-suspended in saline. The suspension was heated at 49.5°C for one hour. The heated cells were washed once with saline and re-suspended in saline. The suspension was then injected intravenously into the subject. Scanning was performed one hour later. Cases of thalassaemia major, sickle cell haemoglobin/thalassaemia and thalassaemia trait have been investigated by this method. All the cases studied, with the exception of one carrier of thalassaemia trait, whose spleen was not palpable, showed varying degrees of splenomegaly. The size and configuration of the spleen could be well demonstrated. A constant finding in spleen scans on patients with congenital haemolytic anaemia, not observed in scans on normal subjects, was the presence of regions of lower average radioactivity throughout the organ. The interpretation of this finding is discussed. (author)

  19. Erythrokinetics, ferrokinetics and red cell survival in sickle cell anaemia under subtropical climatic conditions

    International Nuclear Information System (INIS)

    Ferrokinetic parameters were evaluated with 59Fe and red-cell survival with 51Cr by classical techniques in a total of 17 patients with sickle-cell disease. The mean plasma 59Fe half-disappearance time in these patients was 29.5 min as compared with a normal value of 92 min, and the t1/2 51Cr 8.0 days as compared with a normal value of 26.0 days. The mean red-cell iron turnover rate was elevated to 9 times normal. The increased destruction of red cells appeared to take place predominantly, though not entirely, in the spleen. Eight of the 17 patients studied were identified as having intercurrent complications, but these did not significantly affect the results of the investigations. A group of 5 boys in whom the red-cell iron turnover rate was elevated to a lesser degree than in the other patients were subjected to more detailed studies of plasma 59Fe clearance with particular reference to ineffective erythropoiesis. In these patients, the plasma 59Fe clearance curves showed precocious humps characteristic of ineffective erythropoiesis. Detailed analysis of the results indicated ineffective erythropoiesis corresponding to 3.6, 16.0, 22.6, 32.0 and 50.0 % of the iron initially taken up by the bone marrow. It is concluded that while the anaemia in most patients with sickle-cell disease is mainly due to shortened survival of the circulating red cells, with increased destruction of red cells in the spleen, ineffective erythropoiesis may none the less be an important factor determining the actual degree of this anaemia

    In order to confirm feasibility of MOSFET modality in use of in vivo dosimetry, evaluation of gonad shielding in order to minimize gonadal dose of patients undergoing radiotherapy by using MOSFET modality was performed. Gonadal dose of patients undergoing radiotherapy for rectal cancer in the department of radiation oncology of Seoul National University Hospital since 2009 was measured. 6 MV and 15 MV photon beams emitted from Varian 21EX LINAC were used for radiotherapy. In order to minimize exposed dose caused by the scattered ray not only from collimator of LINAC but also from treatment region inside radiation field, we used box.shaped lead shielding material. The shielding material was made of the lead block and consists of 7.5 cm x 9.5 cm x 5.5 cm sized case and 9 cm x 9.5 cm x 1 cm sized cover. Dosimetry for evaluation of gonad shielding was done with MOSFET modality. By protecting with gonad shielding material, average gonadal dose of patients was decreased by 23.07% compared with reference dose outside of the shielding material. Average delivered gonadal dose inside the shielding material was 0.01 Gy. By the result of MOSFET dosimetry, we verified that gonadal dose was decreased by using gonad shielding material. In compare with TLD dosimetry, we could measure the exposed dose easily and precisely with MOSFET modality.

  2. Vitamin B12 deficiency - a major cause of megaloblastic anaemia in patients attending a tertiary care hospital

    International Nuclear Information System (INIS)

    Folate and vitamin B12 deficiencies have been known to cause megaloblastic anaemia. Since the deficiencies of these two vitamins are very common in Pakistani population, it would be imperative to investigate their role in causing megaloblastic anaemia. The objective of this study was to find out the contribution of folate and vitamin B12 deficiencies in causing megaloblastic anaemia in our patient population. Methods: In this retrospective cohort study, clinical records of 220 patients (101 females and 119 males with an age range of 1 - 80 years) who presented themselves with macrocytic anaemia at the Aga Khan University Hospital were collected. Data pertaining to complete blood count and serum levels of folate and vitamin B12 were analysed. Results: The mean haemoglobin (Hb) level was 6.8 +- 0.2 gm/dl. Sixty-nine percent of the patients had severe anaemia (Hb<8 gm/dl). Mean +- SEM values of haemoglobin, serum folate and serum B12 were not significantly different between males and females (Hb 6.4 +- 0.3 gm/dl vs 6.3 +- 0.3 gm/dl; folate 6.9 +- 0.8 mu g/ml vs 7.8 +- 1 mu g/ml; B12 259 +- 65 mu g/ml vs 225 +- 45 mu g/ml, respectively). Linear regression analysis showed that serum folate was inversely related with the mean corpuscular volume (MCV, p=0.04). Spearman's correlation analysis indicated an inverse mild association between MCV and serum folate (correlation coefficient= -0.18). Folate deficiency was 43.4%, while vitamin B12 deficiency was 78.5% in these patients. Seventy-one percent of folate-deficient patients had vitamin B12 deficiency as well, while 26.1% of patients with B12 deficiency had a co-occurrence of folate deficiency. Conclusion: Vitamin B12 deficiency appears to be the major factor leading to megaloblastic anaemia in our study population. Inadequate dietary intake, over-cooking of our food and poor absorption might be contributing to high prevalence of vitamin B12 deficiency in this population. (author)

    Full Text Available Radiotherapy has impact in oral health especially on the secretion capacity of the salivary glands. Another impact is the increase of Candida albicans colony. Objectives: To evaluate salivary flow in relation with Candida albicans colony in head and neck cancer patients during and after radiotherapy. Methods: Twenty-four head and neck cancer patients in Dharmais Cancer Hospital, Jakarta who were undergoing radiotherapy or had undergone radiotherapy and 24 match healthy volunteers were included in the study. Clinical observation carried out by collecting unstimulated salivary flow rate and followed by culture of Candida in Saboraud agar medium. Data were analyzed statistically by Chi-square. Results: Nasopharynx cancer was the most frequent type of head and neck cancers (87.5% followed by tongue cancer (12.5% and and found in 41-50 years old patients and 51-60 years old patients respectively, with male predilection compare to female (17:7. Approxiamtely 87.5% of subjects showed decreased salivary flow rate (1.01-1.50mL/10min during and after radiotherapy. However, 91.7% of cancer patients had increased C.albicans colony during and after radiotherapy compared to control (p=0.00. Conclusion: This study showed that radiotherapy induced hyposalivation and might increase the C.albicans colony.  

  4. Effect of fractionated regional external beam radiotherapy on peripheral blood cell count

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study was to assess the need for obtaining weekly complete blood count (CBC) values and to identify the pattern of changes in CBC during regional conventional fractionated radiotherapy. Methods and Materials: A retrospective analysis of CBC data on 299 adult cancer patients who received definitive conventional radiotherapy to head and neck (n=95), chest (n=96), and pelvis (n=108) was performed. Temporal patterns and magnitude of change in white blood cells, neutrophils, lymphocytes, and platelets during radiotherapy were examined. Results: There were statistically significant declines in all counts, albeit not clinically significant. Notable differences between disease sites were found. The greatest weekly interval change in counts occurred during the first week of radiotherapy for all groups of patients. The mean WBC nadir values during treatment were 5.8 for head and neck, 6.8 for chest, and 5.4 for pelvis. The nadirs for all counts occurred toward the middle-to-end of radiotherapy. Lymphocytes were found to be more sensitive to radiotherapy than other leukocyte subcomponents. Conclusion: Our study suggests that weekly CBC monitoring is not necessary for all patients undergoing standard fractionated radiotherapy. Baseline blood counts may be used to determine an optimal schedule for monitoring CBCs in patients receiving conventional radiation alone. Reduced monitoring of CBC may result in significant financial savings

  5. The impact of postmastectomy radiotherapy on local control in patients with invasive lobular breast cancer

    International Nuclear Information System (INIS)

    Purpose: The aim of this population-based study was to examine the impact of postmastectomy radiotherapy on the risk of local recurrence in patients with invasive lobular breast cancer (ILC). Methods: The population-based Eindhoven Cancer Registry was used to select all patients with ILC, who underwent mastectomy in five general hospitals in the southern part of Netherlands between 1995 and 2002. Of the 499 patients 383 patients fulfilled the eligibility criteria. Of these patients, 170 (44.4%) had received postmastectomy radiotherapy. The median follow-up was 7.2 years. Fourteen patients (3.7%) were lost to follow-up. Results: During follow-up 22 patients developed a local recurrence, of whom 4 had received postmastectomy radiotherapy. The 5-year actuarial risk of local recurrence was 2.1% for the patients with and 8.7% for the patients without postmastectomy radiotherapy. After adjustment for age at diagnosis, tumour stage and adjuvant systemic treatment, the patients who underwent postmastectomy radiotherapy were found to have a more than 3 times lower risk of local recurrence compared to the patients without (Hazard Ratio 0.30; 95% Confidence Interval: 0.10-0.89). Conclusion: Local control is excellent for patients with ILC who undergo postmastectomy radiotherapy and significantly better than for patients not receiving radiotherapy.

  7. Chronic fatigue in cancer patients treated with radiotherapy

    International Nuclear Information System (INIS)

    Fatigue is one of the most prevalent and profound symptoms related to both malignancy and anti-neoplastic treatment. It is being reported in 60% to 80% of cancer patients. We review the correlation between the cancer-related fatigue syndrome and radiotherapy. In patients undergoing radiotherapy, fatigue is often cumulative and may reach its peak during the last weeks of treatment. The presence of fatigue prior to therapy initiation is the most important predictive factor of the occurrence of radiotherapy-related cancer fatigue syndrome. Occasionally, fatigue persists for a prolonged period of months and even years beyond radiotherapy. Anemia may be one of major causative factors responsible for the development of the cancer-related fatigue syndrome. Fatigue has an enormous physical, mental, emotional, and economic impact on cancer patients, their families and care-providers. The treatment of radiation-related fatigue remains unknown. The initial approach should cover efforts aimed at the correction of potential etiologies, especially anemia. Education concerning fatigue greatly benefits some patients. It seems that exercise may be beneficial in relieving fatigue, bearing in mind that the exercise program for cancer patients should be initiated gradually and significantly individualized. (author)

  9. Radiotherapy of presenile spinal osteoporosis

    International Nuclear Information System (INIS)

    Painfull conditions of presenile spinal osteoporosis may no longer respond to medication or physical therapy. Analgesic radiotherapy coupled with mild physical therapy and if necessary supported by orthopedic measures frequently results in pain relief and physical stability. Fifty-two cases of osteoporosis and osteoporotic spinal fractures illustrate how better longterm results are achieved by increasing the customary dosage and speeding up radiotherapy. (orig.)

    Some studies on radiotherapy for eyelid cancer have been reported, but the optimal radiation doses for different histological types and tumor sizes have not been detailed. So I studied the optimal radiation doses in radiotherapy for eyelid cancer. The patients were fourteen and histological diagnoses were made on the basis of biopsies or surgery before radiotherapy. Surgical cut margins were positive in 10 cases. In 5 of these cases, tumors were visible. There were 9 sebaceous adenocarcinomas (SAC), 4 squamous cell carcinomas (SCC), and 1 basal cell carcinoma (BCC). In 13 of 14 cases, radiation was applied to eyelids in which tumor-surgical cut margin distances were 3 mm or less. The eyeballs were covered with lead or tungsten shields, and the eyelids were irradiated with a total dose of 50 to 66.6 Gy. In 5 cases, radiation was applied prophylactically for ipsilateral pre-auricle lymph node areas. 11 of 13 cases were locally controlled. I gave greater radiation doses for SAC than for SCC or BCC. I also gave greater doses for in visible tumors than for invisible ones. In the acute phase dermatitis, inflammation of the cornea, conjunctivitis, etc. occurred but they were mild. Later reactions were decreased cilia, dry eye, inflammation of cornea, conjunctivitis, discomfort of the scar, etc. Cataracts were also seen, but they were of senile origen. Because 81.8% of the tumors were controlled, this radiation method was useful with salvage therapies to select an optimal radiation dose according to the differences among histological types and tumor sizes. 60% of visible tumors were also controlled so I think that radical therapy using radiation alone is possible.

    2010-09-01

    Modern radiobiology is undergoing rapid change due to new discoveries contradicting the target concept which is currently used to predict dose-response relationships. Thus relatively recently discovered radiation-induced bystander effects (RIBEs), that include additional death, mutation and radio-adaptation in non-irradiated cells, change our understanding of the target concept and broadens its boundaries. This can be significant from a radioprotection point of view and also has the potential to reassess radiation damage models currently used in radiotherapy. This article reviews briefly the general concepts of RIBEs such as the proposed underlying mechanisms of signal induction and propagation, experimental approaches and biological end points used to investigate these phenomena. It also summarises several mathematical models currently proposed in an attempt to quantify RIBE. The main emphasis of this article is to review and highlight the potential impact of the bystander phenomena in radiotherapy. PMID:20857259

  15. Hypnotherapy in radiotherapy patients: A randomized trial

    International Nuclear Information System (INIS)

    Purpose: To determine whether hypnotherapy reduces anxiety and improves the quality of life in cancer patients undergoing curative radiotherapy (RT). Methods and materials: After providing written informed consent, 69 patients were randomized between standard curative RT alone (36 controls) and RT plus hypnotherapy (33 patients). Patients in the hypnotherapy group received hypnotherapy at the intake, before RT simulation, before the first RT session, and halfway between the RT course. Anxiety was evaluated by the State-Trait Anxiety Inventory DY-1 form at six points. Quality of life was measured by the Rand Medical Outcomes Study 36-item Health Survey (SF-36) at five points. Additionally, patients answered a questionnaire to evaluate their experience and the possible benefits of this research project. Results: No statistically significant difference was found in anxiety or quality of life between the hypnotherapy and control groups. However, significantly more patients in the hypnotherapy group indicated an improvement in mental (p < 0.05) and overall (p < 0.05) well-being. Conclusion: Hypnotherapy did not reduce anxiety or improve the quality of life in cancer patients undergoing curative RT. The absence of statistically significant differences between the two groups contrasts with the hypnotherapy patients' own sense of mental and overall well-being, which was significantly greater after hypnotherapy. It cannot be excluded that the extra attention by the hypnotherapist was responsible for this beneficial effect in the hypnotherapy group. An attention-only control group would be necessary to control for this effect

    Full Text Available Iron deficiency anaemia (IDA is the most common nutritional deficiency in the world including developed and developing countries. Despite intensive efforts to improve the quality of life of rural and aboriginal communities in Malaysia, anaemia and IDA are still major public health problems in these communities particularly among children. A randomized, double-blind, placebo-controlled trial was conducted on 250 Orang Asli (aboriginal schoolchildren in Malaysia to investigate the effects of a single high-dose of vitamin A supplementation (200,000 IU on iron status indices, anaemia and IDA status. The effect of the supplement was assessed after 3 months of receiving the supplements; after a complete 3-day deworming course of 400 mg/day of albendazole tablets. The prevalence of anaemia was found to be high: 48.5% (95% CI = 42.3, 54.8. Moreover, 34% (95% CI = 28.3, 40.2 of the children had IDA, which accounted for 70.1% of the anaemic cases. The findings showed that the reduction in serum ferritin level and the increments in haemoglobin, serum iron and transferrin saturation were found to be significant among children allocated to the vitamin A group compared to those allocated to the placebo group (p < 0.01. Moreover, a significant reduction in the prevalence of IDA by almost 22% than prevalence at baseline was reported among children in the vitamin A group compared with only 2.3% reduction among children in the placebo group. In conclusion, vitamin A supplementation showed a significant impact on iron status indices and IDA among Orang Asli children. Hence, providing vitamin A supplementation and imparting the knowledge related to nutritious food should be considered in the efforts to improve the nutritional and health status of these children as a part of efforts to improve the quality of life in rural and aboriginal communities.

    International Nuclear Information System (INIS)

    iron deficiency anaemia (IDA) is a public health problem throughout the world. Childhood iron deficiency anaemia. A prospective survey (systematic, cluster sampling) was carried out among pre-school children in Alshigla area (Khartoum State), to study the prevalence and aetological factors of IDA. 170 children selected for general nutritional evaluation, 110 of them for haemoglobin levels and morphological classification of anaemia, 70 for further investigations(serum iron, unsaturated iron binding capacity, total iron binding capacity). The population at Alshigla were living in poor condition 85.3% relied on water brought by tankers which showed poor hygienic standard, 90% lived in extended families 54.1% had income level less than LS 3000/day irrespective of family size or mode of spending. A sample of 170 children showed (84.1%) normal nutritional status with 4.7% severe cases with high consumption of cereals low meat, fish and poultry group and vitamin C(22.9%). Disease episodes showed 67.7% had diarrhoea, 22.4% had giardia, 12.9% had malaria and 10.6% had worm infestation. This most probably due to unsanitary living condition. Haemoglobin analysis using Enzyme Linked Immunosorbent assay technique (ELISA) for 110 of the children, showed high prevalence of anaemia (96.4%), 66% prevalence of IDA. Further haematological investigations of 50 of the children confirmed them as IDA cases.Thus the high prevalence of IDA in Alshigla was multi-factorial, inadequate take of dietary iron and of vitamin C, high intake of cereals and legumes, low intake of meat, poultry and fish group (MPF),and high tea consumption, thus food provides inadequate supply of iron and were rich in inhibitors of iron absorption. In addition episodes of diseases that may influence food (hence iron) utilisation contributed to the prevalence of IDA

  5. Transverse tomography and radiotherapy

    International Nuclear Information System (INIS)

    This study was intended to delineate the indications for radiotherapy treatment-planning with the help of computerized axial tomography (C.T.) and transverse analog tomography (T.A.T.). Radiotherapy localisation procedures with the conventional method (simulator), with the CT-scanner and with the transverse analog tomograph (T.A.T., Simtomix, Oldelft) were compared. As criterium for evaluation differences in reconstruction drawing based on these methods were used. A certain method was judged ''superior'' to another if the delineation of the target volume was more accurate, if a better impression was gained of the site of (for irradiation) organs at risk, or if the localisation could only be performed with that method. The selected group of patients consisted of 120 patients for whom a reconstruction drawing in the transverse plane was made according to the treatment philosophy. In this group CT-assisted localisation was judged on 68 occasions superior to the conventional method. In a number of cases it was found that a ''standard'' change in a standard target volume, on the base of augmented anatomical knowledge, made the conventional method sufficient. The use of CT-scanner for treatment planning was estimated. For ca. 270/1000 new patients a CT-scan is helpful (diagnostic scan), for 140 of them the scan is necessary (planning scan). The quality of the anatomical information obtained with the T.A.T. does not yet fall within acceptable limits, but progress has been made. (Auth.)

  6. Imaging in radiotherapy

    International Nuclear Information System (INIS)

    The diagnostic methodologies used for the radiotherapy planning have undergone great developments in the last 30 years. Since the 1980s, after the introduction of the CT scanner, the modality for the planning moved beyond the planar 2D assessment to approach a real and more realistic volumetric 3D definition. Consequently the dose distribution, previously obtained by means of an overly simple approximation, became increasingly complex, better tailoring the true shape of the tumour. The final therapeutic improvement has been obtained by a parallel increase in the complexity of the irradiating units: the Linacs for therapy have, in fact, been equipped with a full accessory set capable to modulate the fluence (IMRT) and to check the correct target position continuously during the therapy session (IMRT-IGRT). The multimodal diagnostic approach, which integrates diagnostic information, from images of the patient taken with CT, NMR, PET and US, further improves the data for a biological and topological optimization of the radiotherapy plan and consequently of the dose distribution in the Planning Target Volume. Proteomic and genomic analysis will be the next step in tumour diagnosis. These methods will provide the planners with further information, for a true personalization of the treatment regimen and the assessment of the predictive essays for each tumour and each patient.

    Monitoring an epidemic of an emerging vector-borne disease can be problematic; particularly in a country where vector-borne disease has previously had minimal impact on livestock. This paper describes methods of past and current surveillance of the Theileria-associated bovine anaemia (Ikeda; TABA) epidemic in New Zealand, and the resulting inferences made. Over the three year period of the TABA epidemic a portfolio of surveillance methods has been used: case reporting (with subsidised PCR testing), syndromic surveillance, sentinel surveillance, testing convenience samples for herd infection, as well as specific active surveillance initiatives to understand the tick vector distribution. Surveillance data have shown that the number of affected cattle herds has continued to increase over time with seasonal peaks in spring and autumn coinciding with peak activity of nymph and adult ticks respectively. In spring 2014, the epidemic extended south into areas that were previously considered to be unsuitable for the tick vector. As a result a survey was initiated that showed that ticks were present in areas outside of the known distribution. Testing pooled blood samples from cattle herds across New Zealand showed there still remained a significant percentage of herds where only non-Ikeda type infections were present, indicating that these herds were at risk of future TABA (Ikeda) outbreaks. For some regions there had been a noticeable increase in the percentage of herds infected, yet with only a small increase in the number of outbreaks compared with the previous year. Thus, outbreaks had either gone unobserved or had not been confirmed by testing. In these regions extensive low-input beef farming could explain the non-detection observed. There was a close relationship between the number of syndromic reports of anaemia and the number of confirmed cases of TABA (Ikeda), (P<0.01, adjusted R-squared=0.74). Active monitoring of the epidemic for a three year period has provided

  8. Advances in radiotherapy

    International Nuclear Information System (INIS)

    Radiation therapy is in the midst of a rebirth largely driven by the use of computers for treatment planning and beam delivery. The first edge of this renaissance was the advent of three-dimensional conformal radiation therapy (3-D CRT). This was enabled by the widespread availability and utilization of three-dimensional imaging such as computed tomography and magnetic resonance scanning, themselves products of the computer revolution. For the first time this allowed radiation oncologists to segment and visualize the tumor in association with it neighboring sensitive soft-tissue structures. Software tools to visualize the beam paths through the body enabled the beam directions and beam shapes to be manually optimized. Simultaneously, improved dose calculations utilizing the CT images of the patient anatomy produced more accurate distributions of dose. The dose was delivered with custom-shaped blocks or recently collimators with multiple leaves that allow complex shaped fields to be delivered without the need for block fabrication. In the last couple of decades new treatment delivery methodologies have emerged. The first has been stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT) which is the purview of neurosurgeons (who call it SRS) as well as radiation oncologists (who usually call it SRT). SRS and SRT are premised on multiple beams focusing on one location typically with circular aperture collimators but increasingly with fields shaped by multi-leaved collimators. Often only a single treatment session (the usual for SRS) is used when the treatment volume is small, but for larger lesions several treatment sessions, or fractions, are used (most often for SRT) to allow for normal tissue repair. The new equipment market for SRS and SRT is about 10% of the total for radiation therapy. Intensity-modulated radiation therapy (IMRT) is the latest treatment methodology and its adoption has been extremely rapid, particularly in the United States. IMRT uses

  10. Radiotherapy in a public health

    International Nuclear Information System (INIS)

    The aim of our publication is to evaluate the state of radiotherapy, its role and place in oncology and in the public health system, in order to plan necessities. The cost and economical effectiveness are objectives of the current evaluation. Radiotherapy is strongly dependant of introducing new technologies and the need of gross capital investments. However, their relative cost is reduced due to their long-term use. Because of the serious delay of Bulgaria from the world standards in radiotherapy, the analysis is based on the data published in the scientific literature. The main tendencies and ideas for development are based on the analysis of The Swedish Council on Technology Assessment in Health Care (SBU) and the ESTRO QUARTS project. We use Swedish model for estimating the expenses, having in mind the conditions in Bulgaria (salary, management, patient cares). The main conclusions are: 1) Radiotherapy is basic curative and palliative method in oncology; 2) Bulgarian radiotherapy is at one of the last places in Europe (therapeutic units are 30 years old average, despite their recommended exploitation of 12-20 years); 3) In contradiction to the world tendencies delay grows during the last 10 years; 4) In countries with low or average GDP radiotherapy should be prioritized, due to its low cost in comparison to the other treatment methods in oncology; 5) The need of radiotherapy will continue to grow, this necessitate not only replacement of the old machines but increasing their number 3 times during the next few years; 6) It is necessary to form a modern radiotherapy centers, equipped with at least two compatible units, based on the currently existing radiotherapy departments.

    Hair cortical cell counting (HCCC) represents a non-invasive, in-vivo measure of cell kill in the human integument. Sixty-six patients undergoing conventionally fractionated, external beam radiotherapy for early stage carcinoma of the prostate had groin hair samples counted. This technique is a sensitive and reproducible measure of radiation effect and may have applicability as an in-vivo prediction tool or in the field of biological dosimetry. A repopulative follicular response occurring at 3-4 weeks may explain flattening of the dose response curve

  12. How PET is changing the management of cancer with radiotherapy

    International Nuclear Information System (INIS)

    Information from PET scanning is transforming the management of many malignancies and the impact of PET is likely to increase further as new indications are recognised. PET is of particular value in patients treated with radiotherapy (RT) with curative intent. These patients rarely undergo invasive surgical staging and therefore imaging is crucial in determining the extent of disease before treatment. More accurate staging with PET means that futile aggressive RT or chcmoRT can be avoided in patients with incurable extensive disease. FDG-PET is of proven value in the staging of common metabolically-active malignancies treated with radiotherapy. These include lung cancer, head and neck cancer, lymphomas and oesophageal carcinoma. It has been shown that PET can improve the selection of patients for radical surgery or radiotherapy in lung cancer and that PET-based staging more accurately predicts survival than conventional staging. For those patients that remain eligible for definitive RT after PET. treatment can be more accurately targeted at the tumour and involved regional nodes. The value of PET for treatment planning is enhanced significantly when PET and CT scans are acquired on a combined PET/CT scanner. Fused PET-CT images can be imported into the radiotherapy planning computer and used to accurately target tumour with the best beam arrangement. After treatment, response may be hard to assess with structural imaging. PET-rcsponse to chemotherapy or radiotherapy in non-small cell lung cancer (NSCLC) predicts survival in NSCLC more accurately than CT response. However, PET has much more potential than imaging with FDG alone can realise. Markers such as FLT can be used to image proliferation in tumours, misonidazole or FAZA can be used to image hypoxia and labeled metabolites of anti-cancer drugs such as 5-FU can be used to study pharmacokinetics. New combinations of radiation and drugs may emerge that can be selected based on biological characteristics of

    External-beam radiotherapy has long been challenged by the simple fact that patients can (and do) move during the delivery of radiation. Recent advances in imaging and beam delivery technologies have made the solution--adapting delivery to natural movement--a practical reality. Adaptive Motion Compensation in Radiotherapy provides the first detailed treatment of online interventional techniques for motion compensation radiotherapy. This authoritative book discusses: Each of the contributing elements of a motion-adaptive system, including target detection and tracking, beam adaptation, and pati

  14. Development of targeted radiotherapy systems

    International Nuclear Information System (INIS)

    Conventional or external beam radiotherapy, has been a viable alternative for cancer treatment. Although this technique is effective, its use is limited if the patient has multiple malignant lesions (metastases). An alternative approach is based on the design of radiopharmaceuticals that, to be administered in the patient, are directed specifically toward the target cell producing a selective radiation delivery. This treatment is known as targeted radiotherapy. We have summarized and discussed some results related to our investigations on the development of targeted radiotherapy systems, including aspects of internal dosimetry

  15. Radiotherapy in paediatric oncology

    International Nuclear Information System (INIS)

    Full text: Radiation therapy has always been one of the most powerful tools in the fight against childhood cancer. Since the middle of the last century, we have known that most paediatric tumours are exquisitely sensitive to radiation. The early application of radiotherapy alone led to the first cures of retinoblastoma, Hodgkin lymphoma, as well as certain sarcomas and brain tumours. The generous application of radiation in conjunction with chemotherapy led to further extraordinary increases in survival rates for leukemias, Wilms tumour, sarcomas, and other paediatric malignancies. Over the past 40 years, the overall cure rate for childhood cancer has climbed from 25% to 75% in the USA. With this success, however, came the knowledge that radiation can be associated with significant late effects. We now have a much better understanding of both the benefits and risks of using radiation to treat children as we seek to optimize and refine its role in curative therapy. Leukemias constitute approximately one third of paediatric cancer diagnoses and most of these patients are successfully treated with chemotherapy alone. Central nervous system (CNS) radiation is still recommended for patients at highest risk of CNS failure and total body radiation is useful for the small percentage of patients who require bone marrow transplant. Brain tumours also make up almost one-third of paediatric neoplasms and children with most kinds of brain tumours will require high dose radiotherapy. Many of the other types of paediatric tumours (Wilms, neuroblastoma, sarcomas, etc.) also require radiotherapy as part of curative treatment. There have been considerable advances in radiation technology including three dimensional planning, intensity modulated radiation therapy, and protons. Individual paediatric patients may or may not benefit from advanced technologies based on numerous patient and disease related factors. Examples will be illustrated. We must also be mindful of economic and

    Archived sera from Atlantic salmon (Salmo salar) that returned to the Penobscot River (Maine), Merrimack River (Massachusetts), and Connecticut River (in Massachusetts) from 1995 to 2002 were analysed for antibodies against infectious salmon anaemia virus (ISAV) using an enzyme-linked immunosorbent assay (ELISA). Up to 60 samples were archived per river system per year. In a given year, the number of fish sampled by ELISA for ISAV antibodies in the Penobscot River ranged from 2.9 to 11.2, and the range of salmon sampled in the Merrimack River and the Connecticut River was 31.3-100 and 20.0-67.5, respectively. Archived sera were not available for the 1995 and 2002 year classes from the Connecticut River. In all, 1141 samples were processed; 14 serum samples tested positive for antibodies to ISAV. In the Penobscot River, serum from one fish tested positive in each of the 1995 and 1999 year-class returns, and sera from two fish tested positive in the 1998 returns. In the Merrimack River, sera from four fish tested positive in each of the 1996 and 1997 returns, and sera from two fish were positive in the 2002 return. None of the archived sera from Atlantic salmon that returned to the Connecticut River tested positive. ?? 2009 United States Government, Department of the Interior.

    Feline immunodeficiency virus (FIV) grown in cat lymphocyte and thymocyte cultures was labelled with L-[35S]methionine or [3H]glucosamine and virus-coded proteins were identified using immunoprecipitation. Polypeptides with apparent Mr values of 15K, 24K, 43K, 50K, 120K and 160K were detected. An additional polypeptide of 10K was detected by Western blot analysis. The two highest Mr species sometimes appeared as one band, of which only the 120K polypeptide was glycosylated. In the presence of tunicamycin gp120 was no longer detectable and a non-glycosylated precursor of 75K was found instead. Pulse-chase experiments suggested that the smaller polypeptides p24 and p15 are cleavage products of both p160 and p50. Western blot analysis using a rabbit serum directed against p26 of equine infectious anaemia virus (EIAV) and an anti-EIAV horse serum from a field case of infection revealed a cross-reactivity with p24 of FIV. Cat sera collected late after experimental FIV infection recognized p26 of EIAV, indicating a reciprocal cross-reactivity. PMID:1690264

    Full Text Available Nigeria has the fourth highest prevalence of TB and the highest prevalence of Sickle cell anaemia (SCA in the world. SCA patients have impaired immunity and are vulnerable to TB. Hence, we studied the haematological indices of SCA patients with TB in Nigeria. A total of 23 SCA patients with TB were studied in parallel with equal number of age and sex matched SCA patients without TB. SCA patients with TB had significantly lower haematocrit, higher level of circulating sickle cells (CSCs and similar level of reticulocyte count in comparison to patients without TB. SCA patients with TB had significantly higher mean WBC count associated with higher frequency of neutrophilia in comparison to those without TB. Monocytosis and eosinopenia were exclusively found in SCA patients with TB at frequencies of 52% and 65% respectively. Lymphocyte and basophil counts were normal in all patients with and without TB. Mean platelet counts were high in both patient groups but the frequency of thrombocytosis was significantly higher in patients with TB. SCA patients with TB had significantly higher mean ESR than their counterparts without the infection. The findings of this study  revealed that TB in SCA patients was associated with rising level of CSCs, falling level of haematocrit, sub-optimal reticulocytosis, neutrophilia, monocytosis, thrombocytosis, eosinopenia and rising level of ESR. Hence, SCA patients presenting with these haematological indices should be investigated for TB.

  19. Observations on the pathogenesis of anaemia in fascioliasis and on immunoglobulin metabolism

    International Nuclear Information System (INIS)

    Proline, an excretory/secretory product of liver flukes, was investigated as a possible mediator of anaemia through haemolysis or dyshaemopoiesis in fluke infected animals. Infusion of 700 μmol proline per rabbit per day for 14 days did not significantly alter the halflife (t1/2) of 51Cr labelled erythrocytes nor did it interfere with plasma clearance and utilization of 59Fe in rabbits. Consequently, it was concluded that proline did not interfere with haemoglobin synthesis or induced haemolysis in rabbits at test dose level. The metabolism of radiolabelled IgG was also investigated in calves infected with Fasciola gigantica. In two calves given 1,000 metacercariae of F. gigantica ten weeks earlier, the mean t1/2 of 125I labelled IgG was 74 h, compared with 100 h in uninfected controls. The faecal clearance of 125I labelled IgG was correspondingly higher among infected calves, indicating that serum IgG was being lost into the gut in excessive quantities, probably via the bile.

  20. Evolutionary mechanisms involved in the virulence of infectious salmon anaemia virus (ISAV), a piscine orthomyxovirus

    International Nuclear Information System (INIS)

    Infectious salmon anaemia virus (ISAV) is an orthomyxovirus causing a multisystemic, emerging disease in Atlantic salmon. Here we present, for the first time, detailed sequence analyses of the full-genome sequence of a presumed avirulent isolate displaying a full-length hemagglutinin-esterase (HE) gene (HPR0), and compare this with full-genome sequences of 11 Norwegian ISAV isolates from clinically diseased fish. These analyses revealed the presence of a virulence marker right upstream of the putative cleavage site R267 in the fusion (F) protein, suggesting a Q266 → L266 substitution to be a prerequisite for virulence. To gain virulence in isolates lacking this substitution, a sequence insertion near the cleavage site seems to be required. This strongly suggests the involvement of a protease recognition pattern at the cleavage site of the fusion protein as a determinant of virulence, as seen in highly pathogenic influenza A virus H5 or H7 and the paramyxovirus Newcastle disease virus

    2014-12-01

    Full Text Available The Community added value of Centres of Expertise (CoE and European Reference Networks (ERN is particularly high for rare diseases (RD due to the rarity of these conditions, which implies both a small number of patients and scarcity of expertise within a single country. Gathering expertise at the European level is therefore, paramount in order to ensure equal access to accurate information, appropriate and timely diagnosis and high quality clinical care and follow up for patients with rare diseases. This applies particularly to rare anaemias due to the high number of different rare diseases that constitute this group. In this context, the European Network for Rare and Congenital Anaemias (ENERCA, co-financed by the European Commission, was created in 2002 with the aim of prevention and management of rare anaemias (RA and the development and promotion of policies to improve the well-being of European Union citizens. The ENERCA White Book is a position paper, developed as a deliverable of the ENERCA (phase 3 project that intends to contribute to the creation of a ERN in RA (ERN-RA by preparation of the recommendations and, in particular, the definition of the criteria that CoE, local centres (LC and their interrelations have to fulfil as healthcare providers. It has been nourished by all the activities that have been performed over the past ten years within the ENERCA framework. The White Book is addressed to authorities in charge of the identifying CoE, as an essential requirement for the official recognition of the ERN, to European and national health authorities, Healthcare centres and health professionals, as well as to all other stakeholders interested in RA. It is also addressed to the patients, as a way to empower their community in this process. One particular characteristic of the White Book is the integration of the three main aspects of a CoE: a ethical and legal frameworks to ensure the non-discrimination and non-stigmatisation of rare

    Full Text Available Background: Traditional wisdom is that wound healing is directly related to haemoglobin level in the blood; therefore blood transfusion is given in anaemic patients to raise the haemoglobin level for better wound healing. Methods: Evaluation of wound healing in the form of split thickness skin graft take was done in 35 normovolaemic anaemic patients (haemoglobin level of < 10 gm/ dl and compared with control group (patients with haemoglobin level of 10 or > 10 gm/ dl. Results: There was no statistically significant difference in mean graft take between the two groups. Conclusion: It is not mandatory to keep haemoglobin level at or> 10 g/dL or PCV value at or> 30% for skin graft take, as mild to moderate anaemia per se does not cause any deleterious effect on wound healing; provided perfusion is maintained by adequate circulatory volume. Prophylactic transfusion to increase the oxygen carrying capacity of the blood for the purpose of wound healing is not indicated in asymptomatic normovolemic anaemic patients (with haemoglobin levels greater than 6g/dL without significant cardiovascular or pulmonary disease.

  3. Localised Infection of Atlantic Salmon Epithelial Cells by HPR0 Infectious Salmon Anaemia Virus.

    Directory of Open Access Journals (Sweden)

    Maria Aamelfot

    Full Text Available Infectious salmon anaemia (ISA is an important, systemic viral disease of farmed Atlantic salmon, Salmo salar L. Endothelial cells are the main target cells for highly virulent HPR-deleted ISA virus (ISAV types. Here we examine the pathogenesis of non-virulent ISAV HPR0 infections, presenting evidence of an epithelial tropism for this virus type, including actual infection and replication in the epithelial cells. Whereas all HPR0 RT-qPCR positive gills prepared for cryosection tested positive by immunohistochemistry (IHC and immunofluorescent labelling, only 21% of HPR0 RT-qPCR positive formalin-fixed paraffin-embedded gills were IHC positive, suggesting different methodological sensitivities. Only specific epithelial cell staining was observed and no staining was observed in endothelial cells of positive gills. Furthermore, using an ISAV segment 7 RT-PCR assay, we demonstrated splicing of HPR0, suggesting initial activation of the replication machinery in the epithelial gill cells. Immunological responses were investigated by the expression of interferon-related genes (e.g. Mx and γIP and by ELISA for presence of anti-ISAV antibodies on samples taken sequentially over several months during an episode of transient HPR0 infection. All fish revealed a variable, but increased expression of the immunological markers in comparison to normal healthy fish. Taken together, we conclude that HPR0 causes a localized epithelial infection of Atlantic salmon.

  4. I-131 therapy for hyperthyroidism in carbimazole induced acute aplastic anaemia

    International Nuclear Information System (INIS)

    Full text: We present a case of a 39 year old previously well woman who developed carbimazole-induced acute aplastic anaemia. Following 6 weeks of carbimazole for Grave's disease she presented with fever, sore throat and lethargy and was found to be pancytopaenic. Haemoglobin fell to 79g/l (normal>120g/l), neutrophils to an undetectable level and platelets to 4,000/ml (normal>150,000/ml). From the MIRD schema it was estimated that a therapeutic dose of 444 MBq (12mCi) to treat her hyperthyroidism would deliver a red marrow radiation dose of about 30 mSv, at least an order of magnitude below any expected demonstrable deleterious effect on the marrow. Subsequently a dose of 444 MBq of I-131 was given and within 2 weeks the marrow had begun to recover, eventually to normal. This case would support the use of 1-131 for hyperthyroidism in carbimazole-induced marrow aplasia, even in profoundly depressed marrow

    Sickle cell anaemia (SCA) is the most frequent genetic haemoglobinopathy, which exhibits a highly variable clinical course characterized by hyper-coagulable and pro-inflammatory states, as well as endothelial dysfunction. Extracellular microvesicles are released into biological fluids and play a role in modifying the functional phenotype of target cells. We hypothesized that potential differences in plasma-derived extracellular microvesicles (EV) function and cargo from SCA patients may underlie divergent clinical trajectories. Plasma EV from SCA patients with mild, intermediate and severe clinical disease course were isolated, and primary endothelial cell cultures were exposed. Endothelial cell activation, monocyte adhesion, barrier disruption and exosome cargo (microRNA microarrays) were assessed. EV disrupted the endothelial barrier and induced expression of adhesion molecules and monocyte adhesion in a SCA severity-dependent manner compared to healthy children. Microarray approaches identified a restricted signature of exosomal microRNAs that readily distinguished severe from mild SCA, as well as from healthy children. The microRNA candidates were further validated using quantitative real time polymerase chain reaction assays, and revealed putative gene targets. Circulating exosomal microRNAs may play important roles in predicting the clinical course of SCA, and in delineation of individually tailored, mechanistically-based clinical treatment approaches of SCA patients in the near future.

    The medical records of 21 dogs with concurrent immune-mediated haemolytic anaemia (imha) and severe thrombocytopenia (defined as an automated platelet count of less than 50x10(9)/l, confirmed by the examination of a blood smear) were reviewed. Their mean (sd) age was 5.8 (2.5) years. When compared with the 24,759 dogs in the hospital population for the same period Airedale terriers and dobermanns appeared to be over-represented with odds ratios of 22.5 (95 per cent confidence interval [ci] 5.2 to 97.9) and 7.6 (95 per cent ci 1.8 to 32.7) respectively. The median duration of the dogs' clinical signs was seven days, with a range from one to 17 days. Eleven of the dogs had a history of a tendency to bleed, and 15 had evidence of bleeding when examined. Twenty of the 21 dogs had been treated with glucocorticoids, nine with vincristine, and seven with azathioprine. Their median stay in hospital was four days, with a range from one to 17 days. The median period for which they survived after admission to hospital was five days, with a range from one to 558 days, and 16 of the 21 dogs had died or been euthanased within 30 days of their admission.

    Objectives: To find out the preva-lence of worm infestation and anaemia among pregnant women along with their socio-demographic characteristics, dietary habits and state of personal hygiene and elicit the association, if any, with anemia and worm infestation Materials and methods: A cross-sectional study was carried out among pregnant mothers attending the antenatal clinic at Nasibpur Union Health Center. All antenatal mothers who came for antenatal checkup for the first time to the health centre on two prefixed days of the week during the study period were interviewed. The reports of their stool and haemoglobin examination were followed up. Results: 82% of the pregnant women were suffering from anemia.25% of the study population had worm infestation. Age at marriage, green leafy vegetable, fruit and flesh food intake of at least 4 days a week, use of lemon with food most of the time, avoiding the practice of eating last in the family, handwashing with soap and water before eating and use of footwear outside the house were statically significant with hemoglobin concentration. Only religion and handwashing practice with soap and water before eating had statistically significant association with worm infestation. Conclusion: The study showed that certain protective factors like diet and personal hygiene if addressed at the time of antenatal checkup can reduce the number of cases of anemia significantly.

    Present case report refers to a 48-year-old man with genetic haemochromatosis (C282Y mut/mut) diagnosed at the age of 26. After aggressive iron depleting regimen carried out up to normalization of iron-related indexes, he received a maintenance regimen based on regular phlebotomies for about 20 years. In 2014, a marked reduction of both serum ferritin and transferrin saturation percent, without concomitant anaemia, was noted on two different occasions at 5-month interval. An obscure occult GI bleeding was suspected, but both upper and lower GI tract endoscopy were negative for abnormal findings, as also was a detailed abdominal US scan. The persistence of low iron-related indexes prompted the physicians to perform a videocapsule endoscopy, which showed an ulcerative bleeding lesion in the small bowel, not confirmed however by both anterograde and retrograde double-balloon enteroscopy. Further MRI and PET allowed the identification of a 3.5 cm large lesion, located outside the small bowel wall, suspected to be a gastrointestinal stromal tumour (GIST). A further laparoscopic procedure allowed the resection of 10 cm of midileum, which included the mass, fully consistent with GIST at pathology. PMID:26210325

    Lentiviral vectors are being developed to satisfy a wide range of currently unmet medical needs. Vectors destined for clinical evaluation have been rendered multiply defective by deletion of all viral coding sequences and nonessential cis-acting sequences from the transfer genome. The viral envelope and accessory proteins are excluded from the production system. The vectors are produced from separate expression plasmids that are designed to minimize the potential for homologous recombination. These features ensure that the regeneration of the starting virus is impossible. It is a regulatory requirement to confirm the absence of any replication competent virus, so we describe here the development and validation of a replication competent lentivirus (RCL) assay for equine infectious anaemia virus (EIAV)-based vectors. The assay is based on the guidelines developed for testing retroviral vectors, and uses the F-PERT (fluorescent-product enhanced reverse transcriptase) assay to test for the presence of a transmissible reverse transcriptase. We have empirically modelled the replication kinetics of an EIAV-like entity in human cells and devised an amplification protocol by comparison with a replication competent MLV. The RCL assay has been validated at the 20 litre manufacturing scale, during which no RCL was detected. The assay is theoretically applicable to any lentiviral vector and pseudotype combination.

    Full Text Available BACKGROUND: to discuss and analyse the evolutive, diagnostic and therapeutic features in a patient with recurrent episodes of bleeding from the lower gastrointestinal tract, due to a rare cause. METHODS: the case of a zoung male patient with a severe acute posthaemorrhagic anaemia caused by an serious episode of bleeding from the lower gastrointestinal tract is disscussed. We comment upon the efficiency of our diagnostic procedures and therapeutic strategy in this case, with a final review of the literature. RESULTS: gastro-duodenal endoscopy and colonoscopy couldn't establish the source of bleeding but gave a valuable guide for our suspicions. Not even the scintigraphic study with Tc –99m per technectate was able to give us more information. Laparotomy revealed a Meckel's diverticulum with a bleeding ulcer; segmentary enterectomy was performed. CONCLUSIONS: obviously neither upper nor lower endoscopy could establish the source of bleeding in our case; still they guiding our suspicions toward this kind of lesion. Laparoscopy if available could have established the diagnosis and give the terapeutic solution at the time. Considering the severity of bleeding episods, laparotomy was, at that time, the single valid option; we think it should have been performed much earlier, after the first bleeding episodes.

    Recent technological developments led to develop the concept of focused liver radiation therapy. We must distinguish primary and secondary tumors as the indications are restricted and must be discussed as an alternative to surgical or medical treatments. For hepatocellular carcinoma 5 to 10cm (or more), a conformational radiation with or without intensity modulation is performed. Stereotactic body radiotherapy (SBRT) is being evaluated and is increasingly proposed as an alternative to radiofrequency ablative treatment for primary or secondary tumors (typically less than 5cm). Tumor (and liver) movements induced by respiratory motions must be taken into account. Strict dosimetric criteria must be met with particular attention to the dose-volume histograms to liver and the hollow organs, including cases of SBRT. PMID:27521035

  12. Radiotherapy for bone metastases

    International Nuclear Information System (INIS)

    Between December 1986 and January 1978, 68 patients with bone metastases were analyzed to evaluate the effect of radiation for the relief of pain. The 68 patients, who had a total of 97 lesions, complained of pain caused by their bone metastasis. The good, fair, and poor responses were found to be 18%, 60%, and 22%, respectively. With reference to the primary neoplasms, the effective response rate was 73% in lung cancer, 100% in breast cancer, 75% in gastric cancer, 100% in hepatic cancer, 100% in bladder cancer, 25% in epipharyngeal cancer, and 70% in the other neoplasms. Depending on the cell types of the lung cancer, the effective response rate was 80% for small cell carcinomas, 72% for adenocarcinomas and 40% for squamous cell carcinomas. Our results suggest that radiotherapy for bone metastases is to be recommended, since the effective response rate was 78% for the relief of pain. (author)

  13. Radiotherapy in pancreatic cancer

    International Nuclear Information System (INIS)

    Purpose and approach: to summarize the current knowledge on the role of radiotherapy in the treatment of pancreatic ductal adenocarcinoma (PDAC). The results of meta-analyses, phase III-studies, and phase II-studies using chemoradiation (CRT) and chemotherapy for resectable and non-resectable PDAC are reviewed. Results and conclusion: the role of CRT is undefined in the adjuvant setting but there may be a role as additive treatment after R1 resection. Locally advanced borderline resectable tumors may shrink down and be subject to potentially curative resections. In locally advanced clearly unresectable cancers the effect of CRT as well as chemotherapy is poorly defined and the sequence of chemotherapy and CRT should be re-evaluated. Patients with PDAC should always be treated within studies to identify optimal treatment results. (orig.)

  14. Tumours following retinoblastoma radiotherapy

    International Nuclear Information System (INIS)

    Radioinduced tumours in young patients irradiated in childhood for retinoblastoma take on a particularly deadly aspect. The onset of this true clinical entity characterized by a long post-irradiation latency period induced by a dose above 6000 rads is a real tragedy. The vast majority of patients then enter into a long martyrdom ending in death. The only cure is surgical, but seldom possible. Treatment is limited to palliative radiotherapy, effective for a while, and chemiotherapy as a last resort but often difficult to prescribe. Prevention alone is the answer. The quality and reliability of the radiotherapeutic treatment depend not only on the personal talent of the radiotherapist but above all on the standard of the equipment. A strong reduction in the doses employed as well as recent technological progress improving the material, its precision and reproducibility appear already to have lowered the frequency curve of these fatal radioinduced tumours

    The goal of radiation therapy is to achieve maximal therapeutic benefit expressed in terms of a high probability of local control of disease with minimal side effects. Physically this often equates to the delivery of a high dose of radiation to the tumour or target region whilst maintaining an acceptably low dose to other tissues, particularly those adjacent to the target. Techniques such as intensity modulated radiotherapy (IMRT), stereotactic radiosurgery and computer planned brachytherapy provide the means to calculate the radiation dose delivery to achieve the desired dose distribution. Imaging is an essential tool in all state of the art planning and delivery techniques: (i) to enable planning of the desired treatment, (ii) to verify the treatment is delivered as planned and (iii) to follow-up treatment outcome to monitor that the treatment has had the desired effect. Clinical imaging techniques can be loosely classified into anatomic methods which measure the basic physical characteristics of tissue such as their density and biological imaging techniques which measure functional characteristics such as metabolism. In this review we consider anatomical imaging techniques. Biological imaging is considered in another article. Anatomical imaging is generally used for goals (i) and (ii) above. Computed tomography (CT) has been the mainstay of anatomical treatment planning for many years, enabling some delineation of soft tissue as well as radiation attenuation estimation for dose prediction. Magnetic resonance imaging is fast becoming widespread alongside CT, enabling superior soft-tissue visualization. Traditionally scanning for treatment planning has relied on the use of a single snapshot scan. Recent years have seen the development of techniques such as 4D CT and adaptive radiotherapy (ART). In 4D CT raw data are encoded with phase information and reconstructed to yield a set of scans detailing motion through the breathing, or cardiac, cycle. In ART a set of

Phantom study concerned geographic distortion and the total accuracy of MRSS, the former revealed the result lesser than 1 mm within 90 mm-distance between MR slices and Center of magnetic field, the latter showed maximal errors 2 mm in the field size, and 3 mm in the iso-center. This system was applied to 15 patients with intracranial or head and neck lesions and all procedures were smoothly performed. To evaluate the usefulness of MRSS, 6 radiation oncologists compared the difference between MRSS and CT simulation system in setting radiation field. The results were satisfactory especially in cases with lesions the extent of which was unclear on CT images. It was considered that this system could support the radiotherapy planning for intracranial or head and neck lesions. (author)

  19. Anatomical imaging for radiotherapy

    International Nuclear Information System (INIS)

    The goal of radiation therapy is to achieve maximal therapeutic benefit expressed in terms of a high probability of local control of disease with minimal side effects. Physically this often equates to the delivery of a high dose of radiation to the tumour or target region whilst maintaining an acceptably low dose to other tissues, particularly those adjacent to the target. Techniques such as intensity modulated radiotherapy (IMRT), stereotactic radiosurgery and computer planned brachytherapy provide the means to calculate the radiation dose delivery to achieve the desired dose distribution. Imaging is an essential tool in all state of the art planning and delivery techniques: (i) to enable planning of the desired treatment, (ii) to verify the treatment is delivered as planned and (iii) to follow-up treatment outcome to monitor that the treatment has had the desired effect. Clinical imaging techniques can be loosely classified into anatomic methods which measure the basic physical characteristics of tissue such as their density and biological imaging techniques which measure functional characteristics such as metabolism. In this review we consider anatomical imaging techniques. Biological imaging is considered in another article. Anatomical imaging is generally used for goals (i) and (ii) above. Computed tomography (CT) has been the mainstay of anatomical treatment planning for many years, enabling some delineation of soft tissue as well as radiation attenuation estimation for dose prediction. Magnetic resonance imaging is fast becoming widespread alongside CT, enabling superior soft-tissue visualization. Traditionally scanning for treatment planning has relied on the use of a single snapshot scan. Recent years have seen the development of techniques such as 4D CT and adaptive radiotherapy (ART). In 4D CT raw data are encoded with phase information and reconstructed to yield a set of scans detailing motion through the breathing, or cardiac, cycle. In ART a set of

    Full Text Available With increasing scrutiny of prostate cancer (PCa diagnosis and treatment, much attention has been given to the morbidity caused by radical prostatectomy (RP and/or radiotherapy (RT. One of the most common side-effects of either treatment is erectile dysfunction (ED. [1] Approximately, 40% of patients will experience ED after RT for PCa. The post-RT ED causes significant patient dissatisfaction with cancer treatment as well as decrease in patient and partner psychosocial function. [2] To address this issue in patients undergoing RT, Pisansky et al. [3] conducted a prospective, randomized, double-blinded, placebo-controlled trial to assess the efficacy of a phosphodiesterase enzyme-5 inhibitor (PDE5i, tadalafil, as a preventive measure for patients undergoing RT for PCa and found no difference in erectile function between the control and treatment groups.

  2. Radiotherapy: yesterday, today and tomorrow

    International Nuclear Information System (INIS)

    The inaugural lecture starts with a brief history of the discovery of x-rays and the development of radiotherapy. In a modern radiotherapy department, cancer is diagnosed and mostly treated non-surgically. The modern treatment of many cancers is complex and involves a choice between at least 3 modalities; namely surgery, radiotherapy and cancer chemotherapy. One or a combination of these can be used. A discussion is given of a radiotherapy department as it functions at the University of Cape Town. At the University, cancer is not managed by any one treatment modality, but by a group of specialists who have a major intersest in a particular field. The personnel of the radiotherapy department consists of various people such as a radiographer, radiotherapist, radiobiologist and others, who are all experts in a particular area. Together they form the radiotherapy team. An individual treatment plan is drawn up for each patient. An indication is given of the cost of a major linear accelerator and the patient treatment cost on such an accelerator. Cancer chemotherapy comprises an important part in any radiotherapy department and is used to prevent the appearance of microscopic disease or to reduce and even cure established disease. A summary is given of the cost attached to chemotherapy. An indication of cure rates with the present methods of treatment is given. The reason why oxygen is necessary in the radiation of tumours is discussed. The radiobiologist plays an important role in this respect. A look is also taken at the future prospects of radiotherapy

    International Nuclear Information System (INIS)

    This report aims at assessing safety, indications, the role in therapeutic strategy, and efficiency of contact radiotherapy. It also aims at answering questions like: is the contact radiotherapy technique validated? What are the indications for contact radiotherapy? What about the efficiency and safety of contact radiotherapy? After a presentation of preliminary notions on radiotherapy (radiation types, dose, and irradiation techniques), the report presents this specific technique of contact radiotherapy: definition, devices, use recommendations, issues of radiation protection, modalities of performance of a contact radiotherapy session, and concerned pathologies. Then, based on a literature survey, this report addresses the various concerned tumours (skin, rectum, brain, breast), indicates some general information about these tumours (epidemiological data, anatomy and classification, therapeutic options, radiotherapy), and proposes an assessment of the efficiency and safety of contact radiotherapy

    There is an established role for post-operative radiotherapy in the treatment of benign and malignant salivary gland tumours. For benign disease, the addition of radiotherapy improves local tumour control in cases with incomplete excision, involved surgical margins or multi-focal disease recurrence. After capsule rupture or spillage alone, surveillance should usually be advised. For malignant disease, post-operative radiotherapy is recommended for an advanced tumour stage, high-grade tumour, perineural or lympho-vascular invasion, close or positive resection margins, extra-parotid extension or lymph node involvement. The main benefit is increased loco-regional tumour control, although this may translate into a modest improvement in survival. The possible late side effects of parotid bed irradiation include skin changes, chronic otitis externa, sensorineural hearing loss, osteoradionecrosis and secondary malignancy. Severe complications are rare, but patients should be counselled carefully about the risks. Primary radiotherapy is unlikely to be curative and is reserved to cases in which resection would cause unacceptable functional or cosmetic morbidity or would likely result in subtotal resection (R2) or to patients with distant metastases to gain local tumour control. There are provisional data on the use of charged particle radiotherapy in this setting. Some patients may benefit from synchronous chemotherapy with radiotherapy, but this group is not defined, and data from comparative prospective studies are required before routine clinical use of this treatment.

  5. Education in physics of radiotherapy

    International Nuclear Information System (INIS)

    Radiotherapy is the clinical application which requires the highest precision in dose delivery because of the very high doses administrated to patients, taking into account that new diagnostic methods and new modalities and treatment machines give greater possibilities of dose escalation. These higher doses may also produce serious side effects if not accurately administered. High qualified personnel is therefore needed for dealing with these new complex modalities, assuring that dose prescribed is correctly administered and providing adequate radiation protection to patients, public and staff. Education in Physics of Radiotherapy aims to provide students with solid theoretical and practical basis in order to be able to work with great responsibility and understanding in a Radiotherapy Department and assure that appropriate radiation protection to patients, public and staff. Since 1964 the National Atomic Energy Commission (CNEA) gives course related to Radiotherapy and since 2002, due to a collaborative project, these courses are given at the Oncology Institute 'Angel H. Roffo' (IOAR) which belongs to the University of Buenos Aires (UBA). The IOAR is well equipped in Radiotherapy and new techniques are continuously introduced. That is why, being a University Institution and having highly specialized staff, it is the ideal hospital for teaching Radiotherapy in Buenos Aires, not only for regular courses but also for implementing workshops, seminars and updating courses as well. Continuous education helps to create and increase awareness of the importance of radiation protection in patients as well as in public and staff. (author)

Its incidence is higher in immunocompromised hosts than in the general population. In children and during hemodialysis, TB is characterized by the frequency of extrapulmonary localizations and diagnostic difficulties. The aim of this retrospective study is to evaluate the incidence of TB in Tunisian children undergoing hemodialysis and to determine its clinical features as well as the results of chemotherapy.Method: This retrospective study includes seven TB children among 112 children on hemodialysis at the pediatric nephrology department in Charles Nicolle Hospital from 2002 to 2008. The diagnosis of TB was established by a combination of clinical, radiological, biochemical, microbiological, and histological examinations. Treatment with anti-TB drugs, the results of therapy, and the outcome of patients were noted.Results: There were four girls and three boys aged 10 to 16 years (mean, 13 years. They had been on hemodialysis for 2 to 5 years (mean, 3 years. Noted clinical features were weight loss and fever in five cases, chest pain in one case, cervical lymph node in one case, and spinal pain in one case. The organ systems involved were pleural in two cases, pulmonary in one case, peritoneal in one case, cervical lymphatic in one case, and spinal in one case. One patient was treated empirically with a good response. Diagnosis was made by isolation of mycobacterium TB in three cases, by specific histological signs observed in a lymph node biopsy in one case, in peritoneal biopsy in one case, and in discovertebral biopsy in one case. In the remaining patient, the clinical and radiological presentations were compatible with pulmonary TB. All patients received four anti-TB drugs: isoniazid, rifampicin, pyrazinamide

    This review article focuses on clinically relevant radioprotectors and their mechanisms of radioprotection. Radiotherapy is the most common modality of human cancer therapy. Obtaining optimal results requires a judicious balance between the total dose of radiotherapy delivered and the threshold limit of critical surrounding normal tissues, and the normal tissues need to be protected against radiation injury to obtain better tumor control by using a higher dose. For this reason, radiation-protective agents play an important role in clinical radiotherapy. Radiation-protective agents can be classified into three groups: radioprotectors, adaptogens, and absorbents. The first group generally consists of sulfhydryl compounds and other antioxidants. They include several myelo-, entero-, and cerebro-protectors. Adaptogens act as promotors of radioresistance. They are natural protectors that offer chemical protection against low levels of ionizing radiation. Absorbents protect organs from internal radiation and chemicals. They include drugs that prevent incorporation of radioiodine by the thyroid gland and absorption of radionuclides. This article thoroughly describes the properties, mechanisms of action, and perspectives on clinical application of the following categories of radioprotectors: sulfhydryl compounds (e.g., cysteine, cysteamine, glutathione, AET, WR 2127, and other WR-compounds), antioxidants (e.g., tempace, Hoechst 33342, vitamin A, E, and C, TMG, melatonin), angiotensin-converting enzyme (ACE) inhibitors (e.g., captopril, elanopril, penicillamine, pentoxifylline, L-158, 809), cytoprotective agents (mesna, dexrazoxane, and amifostin), metalloelements (e.g., manganese chloride, cadmium salts, bismuth subnitrate), immunomodulators (gamma-interferon, polysaccharides AM5, AM218, heat-killed lactobacillus cells, broncho-vaxom, trehalose dicorynomycolate, and AS101), lipopolysaccharides and prostaglandins, plant extracts and compounds isolated from plants (curcmin

    Full Text Available The aim of this study was to evaluate the early acute side effects following radiation and chemotherapy in patients with head and neck cancer (HNC, namely: to ascertain main patient complaints; to investigate saliva properties and to determine the microecology of the oral cavity in patient with HNC before and after radiation and chemotherapy. Eighteen patients with HNC which were prescribed gamma therapy on two buccal submandibular fields combined with close-focus roentgenotherapy and methotrexate as a cytostatic were examined. It was established that 3 weeks after the radio- and chemotherapy 100 % of patients pointed at xerostomia, dysgeusia, disturbances during speech, burning, pricking and itching in oral cavity. After cancer treatment the speed of salivation decreased two times and pH was 15 % lower than before radio and chemotherapy. Anti-cancer treatment caused significant decrease of lysozyme level (34 % lower and secretory immunoglobulin A (1,5 times lower in patients with HNC. After radio and chemotherapy different fungi of Candida genus from oral cavity were inoculated in high concentrations (from 4,0 ± 0.07 to 6,9 ± 0.07 lg CFU/ml, such as С. Аlbicans, C. Kruzei, С. Tropicalis, C. Stellatoidea.Thus significant negative changes from the side of speed and character of salivation, decrease of saliva pH, depression of both non-specific and specific components of immune defense and high contamination of oral mucosa with fungi of Candida genus considerably worsenpost-cancer rehabilitation.

    Pain in head and neck cancer represents a major issue, before, during and after the oncological treatments. The most frequent cause of pain is chemo/radiation related oral mucositis, which involves 80% of the patients and worsens their quality of life inhibiting speaking, eating, drinking or swallowing and sometimes reducing the treatment compliance, the maximum dose intensity and thus the potential efficacy of treatment. Nevertheless pain is still often under estimated and undertreated. An Italian multidisciplinary group of head and neck cancer specialists met with the aim of reaching a consensus on pain management in this setting. The Delphi Appropriateness method was used for the consensus. External expert reviewers evaluated the final statements. The paper contains 30 consensus-reached statements about pain management in HNC patients and offers a review of recent literature in these topics. PMID:26712589

  12. Management in progression of prostatic adenocarcinoma after definitive radiotherapy

    International Nuclear Information System (INIS)

    Follow-up of prostate cancer patients after radical radiotherapy includes clinical examination, periodical measurements of PSA level, bone scan and CT or x-ray examinations. Biochemical progression (3 consecutive results of elevated PSA) does not always equal clinical progression. In all patients with elevated PSA it is necessary to confirm, diagnose or to exclude local progression, which has to be distinguished from systemic progression. All patients should undergo bone scan, chest x-ray and ultrasound of the abdomen. Digital rectal and transrectal ultrasound examinations are vital for local relapse assessment. To confirm local progression (up to 30% of biochemical progressions) rebiopsy (tru-cut) may be performed, but pathological interpretations of findings are difficult due to post-radiotherapy alterations and inflammatory reactions. In selected cases salvage local treatment may be offered after pathological confirmation of the local relapse, although usually patients are offered hormonal therapy only. Because the number of young and fit patients diagnosed with recurrent prostate cancer is increasing some institutions introduce salvage brachytherapy after local failure of radical radiotherapy. The data concerning this management is scant, but promising. (author)

    Hydroxycarbamide (hydroxyurea) provides laboratory and clinical benefits for adults and children with sickle cell anaemia (SCA). Given its mechanism of action and prior reports of genotoxicity, concern exists regarding long-term toxicities and possible carcinogenicity. We performed cross-sectional analyses of chromosome stability using peripheral blood mononuclear cells (PBMC) from 51 children with SCA and 3-12 years of hydroxycarbamide exposure (mean age 13·2 ± 4·1 years), compared to 28 children before treatment (9·4 ± 4·7 years). Chromosome damage was less for children receiving hydroxycarbamide than untreated patients (0·8 ± 1·2 vs. 1·9 ± 1·5 breaks per 100 cells, P = 0·004). There were no differences in repairing chromosome breaks after in vitro radiation; PBMC from children taking hydroxycarbamide had equivalent 2 Gy-induced chromosome breaks compared to untreated patients (30·8 ± 16·1 vs. 31·7 ± 8·9 per 100 cells, P = not significant). Radiation plus hydroxycarbamide resulted in similar numbers of unrepaired breaks in cells from children on hydroxycarbamide compared to untreated patients (95·8 ± 44·2 vs. 76·1 ± 23·1 per 100 cells, P = 0·08), but no differences were noted with longer exposure (97·9 ± 42·8 breaks per 100 cells for 3-6 years of hydroxycarbamide exposure vs. 91·2 ± 48·4 for 9-12 years of exposure). These observations provide important safety data regarding long-term risks of hydroxycarbamide exposure for children with SCA, and suggest low in vivo mutagenicity and carcinogenicity. PMID:21542824

    Full Text Available Background: Many adolescents with sickle cell disease (SCD have adjustment difficulties in the transition period from paediatric care to the adult system because they find themselves in unfamiliar waters where they have to learn to manage themselves. The aim of this study is to evaluate the prevalent crises and morbidities associated with SCD in adolescents in Babcock University Teaching Hospital (BUTH, to also assess the level of knowledge of these adolescents about SCD and to determine their emotional response to the disease. Materials and Methods: This was a retrospective review of case notes of adolescents with sickle cell anaemia that were seen in BUTH, from May 2013 to April 2014. Data extracted from the case notes was entered into a Microsoft (MS Excel and analysed using descriptive statistics. Results were presented in tables. Results: A total of 50 subjects were seen in the department during this study period. Vaso-occlusive crises in the form of bone pains (93.1% were the commonest crises encountered. Associated morbidities were malaria 34 (85%, tonsilitis 1 (2.5%, pneumonia 1 (2.5%, leg ulcer 1 (2.5%, azotaemia 1 (2.5% and subarachnoid haemorrhage 2 (5%. Majority (88% had adequate knowledge about general health maintenance while knowledge on nutrition and appropriate analgesia use is still inadequate. Eleven (22% had symptoms of depression, four (8% had suicidal ideation while one (2% had a history of attempted suicide. Conclusion: This study emphasizes the importance of psychosocial intervention as part of a comprehensive health management for people with SCD.

  15. Integrity of the iron transport process in mice with X-linked anaemia

    International Nuclear Information System (INIS)

    The defect in iron (Fe) absorption in X-linked anaemia (sla) remains an enigma; absorption of a tracer dose of Fe is impaired in mice raised on an iron-containing cube diet but not in those raised on an iron-deficient diet. Because cobalt (Co) shares a similar intestinal transport pathway with Fe, a study was made of the effect of iron deficient diet on Co absorption. The duodenum of sla and genetically normal mice was perfused for 30 min with labelled solutions containing Co or Fe. Co uptake and transfer were similar in sla and normals fed cubes whereas Fe uptake and transfer were less in sla than in normals. The iron deficient diet caused an increase in the uptake and transfer of Co and Fe in sla and normals. When Co and Fe were perfused together in sla fed deficient diet, the uptake and transfer of each metal was less than when perfused alone. The distribution of Fe and Co in subcellular mucosal fractions was determined by a differential centrifugation technique. Deficient diet resulted in a directionally similar change in the subcellular distribution of Co and Fe in sla and normals. The increase in Co as well as Fe absorption in the sla on an iron deficient diet to the same high level found in genetically normal animals, and the inhibitory effect of each metal on the absorption of the other suggests that the absorption defect in sla is unlikely to be due to a primary defect in the function of the transport carrier.

    Full Text Available Fanconi anaemia (FA is a rare genetic chromosomal instability syndrome caused by impairment of DNA repair and reactive oxygen species (ROS imbalance. This disease is also related to bone marrow failure and cancer. Treatment of these complications with radiation and alkylating agents may enhance chromosomal breakage. We have evaluated the effect of amifostine (AMF on basal and mitomycin C (MMC-induced chromosomal breakage in FA blood cells using the micronucleus assay. The basal micronuclei count was higher among FA patients than healthy subjects. Pre-treatment with AMF significantly inhibited micronucleation induced by MMC in healthy subjects (23.4 ± 4.0 – MMC vs 12.3 ± 2.9 – AMF →MMC MN/1000CB, p < 0.01, one way ANOVA as well as in FA patients (80.0 ± 5.8 – MMC vs 40.1 ± 5.8 – AMF →MMC MN/1000CB, p < 0.01, ANOVA. Release of ROS by peripheral blood mononuclear cells treated with AMF →MMC and measured by chemoluminometry showed that AMF-protection was statistically higher among FA patients than in healthy individuals. Based on these results we suggest that AMF prevents chromosomal breakage induced by MMC, probably by its antioxidant effect.

    2011-09-01

    Full Text Available  Determination of eye absorbed dose during head & neck radiotherapy is essential to estimate the risk of cataract. Dose measurements were made in 20 head & neck cancer patients undergoing 60Co radiotherapy using LiF(MCP thermoluminescent dosimeters. Head & neck cancer radiotherapy was delivered by fields using SAD & SSD techniques. For each patient, 3 TLD chips were placed on each eye. Head & neck dose was about 700-6000 cGy in 8-28 equal fractions. The range of eye dose is estimated to be (3.49-639.1 mGy with a mean of maximum dose (98.114 mGy, which is about 3 % of head & neck dose. Maximum eye dose was observed for distsnces of about 3 cm from edge of the field to eye.
