Continued exposure to silica after diagnosis of silicosis in Brazilian gold miners,

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 10 2006
Ana Paula Scalia Carneiro PhD
Abstract Background There is a paucity of studies analyzing the effect of continued silica exposure after the onset of silicosis with regard to disease progression. The present study investigates differences in clinical and radiological presentation of silicosis among former workers with a diagnosis of silicosis, and compares workers who continued to be exposed to silica with those who stopped silica exposure after having received their diagnosis. Methods A sample of 83 former gold miners with a median of 21 years from the first diagnoses of silicosis, had their clinical and occupational histories taken and underwent both chest radiography (International Labor Organization standards) and spirometry. Their silica exposure was assessed and an exposure index was created. The main outcome was the radiological severity of silicosis and tuberculosis (TB). The statistical analysis was done by multiple logistic regression. Results Among the 83 miners, 44 had continued exposed to silica after being diagnosed with silicosis. Continuation of silica exposure was associated with advanced radiological images of silicosis (X-ray classification in category 3, OR,=,6.42, 95% CI,=,1.20,34.27), presence of coalescence and/or large opacities (OR,=,3.85, CI,=,1.07,13.93), and TB (OR,=,4.61, 95% CI,=,1.14,18.71). Conclusions Differential survival is unlikely to explain observed differences in silicosis progression. Results reinforce the recommendation that silica exposure should be halted at an early stage whenever X-ray is suggestive of the disease. Am. J. Ind. Med. 49:811,818, 2006. © 2006 Wiley-Liss, Inc.

Tamoxifen and contralateral breast cancer in BRCA1 and BRCA2 carriers: An update

INTERNATIONAL JOURNAL OF CANCER, Issue 9 2006
Jacek Gronwald
Abstract Women with a mutation in BRCA1 or BRCA2 face a lifetime risk of breast cancer of ,80%, and following the first diagnosis the10-year risk of contralateral breast cancer is ,30%. It has been shown that both tamoxifen and oophorectomy prevent contralateral breast cancer, but it is not clear whether there is a benefit in giving tamoxifen to women who have previously undergone an oophorectomy. Furthermore, the relative degree of protection in BRCA1 and BRCA2 carriers has not been well evaluated. We studied 285 women with bilateral breast cancer and a BRCA1 or BRCA2 mutation, and 751 control women with unilateral breast cancer and a BRCA1 or BRCA2 mutation in a matched case-control study. Control women were of similar age and had a similar age of diagnosis of breast cancer and had been followed for as long as the case for a second primary breast cancer. The history of tamoxifen use for treating the first breast cancer was compared between bilateral and unilateral cases. The multivariate odds ratio for contralateral breast cancer associated with tamoxifen use was 0.50 for carriers of BRCA1 mutations (95% CI, 0.30,0.85) and was 0.42 for carriers of BRCA2 mutations (95% CI, 0.17,1.02). The protective effect of tamoxifen was not seen among women who had undergone an oophorectomy (OR = 0.83; 95%CI, 0.24,2.89) but this subgroup was small. In contrast, a strong protective effect of tamoxifen was apparent among women who were premenopausal or who had undergone natural menopause (OR = 0.44; 95% CI, 0.27,0.65). © 2005 Wiley-Liss, Inc.

First palaeopathological example of Kienböck's disease from early modern Sakhalin Ainu

INTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 2 2002
M. Nakai
Abstract A disorder of the carpal lunate has been diagnosed as Kienböck's disease in a skeleton of a middle-aged Ainu male that was excavated from Sakhalin Island, northeast Asia. The bone lesion is primarily and unilaterally associated with the right wrist, where the right carpal lunate is collapsed and the radiocarpal joint shows degenerative arthritis. Interestingly, the left arm is more robust than the right and the left elbow shows considerable osteoarthritis. The most plausible explanation for these pathologies is that after developing Kienböck's disease in the right wrist, excessive use of the left arm made his left arm robust and finally gave rise to osteoarthritis in the left elbow. In archaeology, where only a few osteochondroses have been reported up until now, the present example is the first diagnosis of Kienböck's disease in skeletal remains.

Sequential immunohistochemical p53 expression in biopsies of oral lichen planus undergoing malignant evolution

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 3 2001
Guido Valente
Abstract: Transformation in squamous cell carcinoma (SCC) may occur in a small percentage of patients affected by oral lichen planus (OLP), but the pathogenesis remains to be elucidated. Overexpression of p53 protein was investigated immunohistochemically in 28 cases of OLP, followed up by sequential biopsies for up to 96 months. In 15 cases (Group 1), no dysplastic changes or neoplastic transformation occurred during the follow-up period; in 7 cases, OLP and SCC were synchronously observed (Group 2), whereas in another 6 cases (Group 3) SCC developed several months or years after diagnosis of OLP. The percentage of p53-positive epithelial cells at first diagnosis was significantly higher in the cases of Groups 2 and 3 than in those of Group 1. In contrast, evaluation of growth fraction by MIB-1 monoclonal antibody did not show any statistical differences among the three groups. Although no conclusions can be drawn about the molecular pathway leading to neoplastic transformation of OLP, or about the role of p53, the results indicate that immunohistochemical evaluation of p53 expression may be a practical tool to select cases of OLP with a high risk of neoplastic transformation.

M. ETMINAN
Summary Background, Gastrointestinal injuries including gastric ulcers have been reported with oral bisphosphonate therapy. However, the risk of the more serious upper gastrointestinal bleeding (UGB) especially in the community setting with these drugs remains unknown. Similarly, the risk of UGB among users of both bisphosphonates and non steroidal anti-inflammatory drugs (NSAIDs) in the community is also unknown. Aim, To explore the risk of more serious UGB among users of bisphosphonates and the risk of UGB among users of both bisphosphonates and NSAIDs in the community. Methods, We conducted a case-control study within a cohort of Quebec residents who had received a revascularization procedure from 1995 to 2004. Cohort members were followed up from the date of their first procedure until the earliest of: (1) study outcome, (2) date of death or (3) end of health care coverage. Cases were defined as those with the first diagnosis of a UGB. For each case, 20 controls were selected and matched to the cases by index date, age and cohort entry. Adjusted odds ratios for current use of bisphosphonates, NSAIDs and co-therapy of both drugs were computed. Results, Within the initial cohort, 3253 incident cases of UGBs and corresponding 65 060 matched controls were identified. The adjusted odds ratio (OR) for UGB by current users of bisphosphonates was 1.01 (95% CI, 0.72,1.43). Current NSAID use was associated with an increased risk of UGB OR = 1.75; 95% CI, 1.53,1.99. The OR for use of bisphosphonates and NSAIDs was elevated OR = 2.00; 95% CI, 1.12,3.57. This risk was still elevated for users of bisphosphonates and COX-2 inhibitors [OR = 2.38 (95% CI, 1.26,4.50)]. Conclusion, We found no evidence of an increase in the risk of UGB among current users of bisphosphonates. The risk of combined NSAID and bisphosphonate therapy was increased, but this risk was not higher than the risk for NSAID users alone. [source]


Systematic review: the epidemiology of gastro-oesophageal reflux disease in primary care, using the UK General Practice Research Database

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 5 2009
H. EL-SERAG
Summary Background, Gastro-oesophageal reflux disease (GERD) is a common diagnosis in primary care; however, there has been no comprehensive review of the epidemiology of GERD in this setting. Aim, To review systematically articles that used the General Practice Research Database to study the epidemiology of GERD. Methods, Systematic literature searches. Results, Seventeen articles fulfilled the inclusion criteria. The incidence of GERD in primary care was 4.5 new diagnoses per 1000 person-years in 1996 (95% CI: 4.4,4.7). A new diagnosis of GERD was associated with being overweight, obese or an ex-smoker. Prior diagnoses of ischaemic heart disease, peptic ulcer disease, nonspecific chest pain, nonspecific abdominal pain, chronic obstructive pulmonary disease and asthma were associated with a subsequent new GERD diagnosis. A first diagnosis of GERD was associated with an increased risk of a subsequent diagnosis of oesophageal adenocarcinoma, oesophageal stricture, chronic cough, sinusitis, chest pain, angina, gallbladder disease, irritable bowel syndrome or sleep problems. Mortality may be higher in patients with a GERD diagnosis than in those without in the first year after diagnosis, but not long term. Conclusion, The General Practice Research Database is an effective way of studying the epidemiology of GERD in a large population-based primary care setting. [source]


Time trends in first-diagnosis rates of colorectal adenomas: a 24-year population-based study

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2008
V. COTTET
Summary Background, Little is known about the descriptive epidemiology of colorectal adenomas diagnosed in the population. Aim, To describe time trends in the rate of first diagnosis of colorectal adenomas and estimate the proportion of adenoma-bearing individuals detected over a 24-year period. Methods, A total of 11 027 patients were first-diagnosed with colorectal adenomas among Côte-d'Or residents (France) between 1976 and 1999. Annual percentage changes were estimated using a Poisson regression model. The proportion of diagnosed adenoma-bearing individuals was estimated using the prevalence of adenomas in an autopsy study performed in the area. Results, Standardized diagnosis rates were 89.6/100 000 men and 50.3/100 000 women. During the period 1976,1993, diagnosis rates significantly increased with annual percentage changes in men and women of respectively +17.1% and +22.3% for proximal adenomas, +7.5% and +9.1% for distal adenomas and +7.2% and +8.0% for advanced adenomas. Changes were less marked during the period 1994,1999. The estimated proportion of adenoma-bearing individuals diagnosed during the 24-year period was 20.0% in men and 16.0% in women. Conclusion, Despite a marked increase in the rate of first adenoma diagnosis, the proportion of diagnosed adenoma-bearing individuals seems too low to induce a significant decrease in colorectal cancer incidence.

Intracavitary cisplatin therapy for pediatric malignancies,

PEDIATRIC BLOOD & CANCER, Issue 3 2010
Howard M. Katzenstein MD
Abstract Background Local control is essential for the successful treatment of pediatric solid tumors. Complete excision is often not possible and local control therapies are limited. Intracavitary cisplatin (IC-CDDP) may be utilized to supplement local control. The aim of the study was to determine the toxicity and efficacy of locally instilled intracavitary cisplatin in patients with recurrent tumors in closed body cavities. Procedure From 2001 to 2009, 12 patients (1,20 years) with recurrent or unresectable malignant tumors were treated with IC-CDDP. Nine had pulmonary lesions. Three patients had abdominal tumors. CDDP (200,mg/m2) was instilled by chest tube or Tenckhoff catheter. Patients were shifted every 15,30,min to allow distribution. After 4,hr, residual was drained by gravity. In 10/13 courses, sodium thiosulfate (STS) was administered to prevent nephrotoxicity. Three other patients received amifostine. Results Malignant pleural effusions resolved in 5/7 patients. This response was temporary in three patients. No patients had ascites prior to treatment. Three patients are alive and disease-free, 18 months, 4 years, and 6 years from treatment. They also had surgery and chemotherapy. Transient renal toxicity was noted in most patients. One patient, treated with amifostine, had persistent renal dysfunction. Conclusions IC-CDDP was effective in treating malignant pleural effusions and may be a palliative option for refractory disease. Long-term survival was achieved in two patients, treated at first diagnosis. The benefit of IC-CDDP in these patients is difficult to assess. Renal dysfunction is usually mild, and typically resolves, but warrants preventive measures with IC-CDDP therapy. Pediatr Blood Cancer. 2010;55:452,456. © 2010 Wiley-Liss, Inc. [source]


Expression of MAC-1 (CD11b) in acute myeloid leukemia (AML) is associated with an unfavorable prognosis

AMERICAN JOURNAL OF HEMATOLOGY, Issue 4 2006
Michaela Graf
Abstract There is evidence to suggest, that cellular adhesion molecules and receptors could play a role in leukemia, e.g., through altered adhesive qualities of leukemic blasts. We have studied the expression of the ,2 -integrin Mac-1 (CD11b) on mononuclear cells in 48 patients with AML at first diagnosis by flow cytometry using a direct fluorescein-conjugated antibody. A case was defined as positive if more than 20% of the cells expressed Mac-1. Within the FAB types, we observed a high expression rate in cases with M5 (100% MAC-1+ cases, 73% MAC-1+ cells), M4 (75% MAC-1+ cases, 48% MAC-1+ cells) and in cases with FAB-M1 with 71% MAC-1+ cases and 29% MAC-1+ cells. Separating our patients' cohort in cytogenetic risk groups, we could detect significant higher proportions of MAC-1+, cases (88% vs. 27%, P = 0.005) and cells (51% vs. 16%, P = 0.015) with poor cytogenetic risk compared to the favorable risk group. For clinical evaluations only patients treated according to the protocols of the German AML Cooperative Group (AML-CG) were included (n = 29, cases with AML-M3 were excluded). More MAC-1+ cases and cells were found in the "non-responders" group (n = 8) compared to the "responders" group (n = 24). We can conclude that AML cases with high MAC-1 expression are characterized by a worse prognosis. Evaluation of MAC-1 expression in AML might therefore contribute clinically important data with respect to develop new therapies that influence the interactions between integrins like MAC-1 on leukemic cells and endothelial or immunoreactive cells.

Supportive-expressive group therapy for women with metastatic breast cancer: survival and psychosocial outcome from a randomized controlled trial

PSYCHO-ONCOLOGY, Issue 4 2007
David W. Kissane
Abstract Background: Mixed reports exist about the impact of supportive-expressive group therapy (SEGT) on survival. Methods: From 485 women with advanced breast cancer recruited between 1996,2002, 227 (47%) consented and were randomized within an average 10 months of cancer recurrence in a 2:1 ratio to intervention with 1 year or more of weekly SEGT plus three classes of relaxation therapy (147 women) or to control receiving three classes of relaxation therapy (80 women). The primary outcome was survival; psychosocial well-being was appraised secondarily. Analysis was by intention-to-treat. Results: SEGT did not prolong survival (median survival 24.0 months in SEGT and 18.3 in controls; univariate hazard ratio for death 0.92 [95% CI, 0.69,1.26]; multivariate hazard ratio, 1.06 [95% CI, 0.74,1.51]). Significant predictors of survival were treatment with chemotherapy and hormone therapy (p<0.001), visceral metastases (p<0.001) and advanced disease at first diagnosis (p<0.05). SEGT ameliorated and prevented new DSM-IV depressive disorders (p = 0.002), reduced hopeless,helplessness (p = 0.004), trauma symptoms (p = 0.04) and improved social functioning (p = 0.03). Conclusions: SEGT did not prolong survival. It improved quality of life, including treatment of and protection against depression. Copyright © 2007 John Wiley & Sons, Ltd. [source]


Aneusomy of chromosomes 7 and 17 predicts the recurrence of transitional cell carcinoma of the urinary bladder

BJU INTERNATIONAL, Issue 1 2000
A.D. Watters
Objective,To determine if changes in chromosome 7 and 17 copy number can be used to predict recurrence in patients with primary noninvasive (pTa) or superficially invasive (pT1) transitional cell carcinoma (TCC) of the urinary bladder. Patients and methods,Tissue specimens for 129 tumours from 52 patients (38 men and 14 women) with pTa/pT1 TCC at first diagnosis were retrieved from pathology archives. All patient notes were accessed and disease outcome documented for superficial (pTa/pT1) recurrence or progression to detrusor muscle invasion ( pT2). The tumours were examined for chromosomal copy number of chromosomes 7 and 17 using fluorescence in situ hybridization (FISH) with chromosome-specific probes. The copy number of chromosomes 7 and 17 was determined in interphase nuclei on intact 6 µm tissue sections. Results,Aneusomy of chromosomes 7 and 17 was detected in the index primary tumours of 10 of 32 (31%) patients with subsequent recurrent disease. No aneusomy for these chromosomes was detected in primary tumours from 20 patients with no detect-able recurrence (P = 0.0082). The relative risk of recurrence was 3.62 times greater (95% confi-dence interval 1.6,8.1, Cox's multiple regression P = 0.0019) for patients with chromosomal aneusomy in primary TCC. Neither stage nor grade of the primary tumours was associated with recurrence in these patients, nor was there a significant association with increased grade (G2/3) or stage ( pT2) at recurrence. Conclusion,These results suggest that the measurement of aneusomy by FISH, using markers for chromosomes 7 and 17, predict recurrence in a subgroup of patients with pTa/pT1 tumours at presentation. This finding may offer a new objective and quantitative test for patients destined to recur. [source]


Accuracy of the BRCAPRO model among women with bilateral breast cancer

CANCER, Issue 4 2009
Kaylene J. Ready MS
Abstract BACKGROUND: The likelihood of identifying a BRCA mutation was often calculated using the BRCAPRO model. A previous study suggested that this model may overestimate the chance of detecting a BRCA mutation among women diagnosed with bilateral breast cancer. Studies also suggested that few patients with bilateral breast cancer whose age at first diagnosis is >40 years were mutation carriers. The objectives of this study were to determine the accuracy of the BRCAPRO model among women with bilateral breast cancer and to determine whether their mutation status was dependent on their age at first diagnosis. METHODS: A retrospective chart review was performed. Women who were diagnosed with bilateral or unilateral breast cancer and who had undergone comprehensive BRCA1 and BRCA2 genetic testing at M. D. Anderson Cancer Center between 1997 and 2006 were included in the study. RESULTS: For individuals with pre-test carrier probabilities >31%, the proportion of positive tests was significantly lower than predicted by the BRCAPRO model (P < .05). In addition, the carrier rate of BRCA mutations was significantly higher (P = .002, Fisher exact test) in women with bilateral breast cancer whose age at first diagnosis was ,40 years compared with those diagnosed >40 years. CONCLUSIONS: The BRCAPRO model was overestimating the relative contribution bilateral breast cancer had on the likelihood of detecting a BRCA1 or BRCA2 mutation. Bilateral breast cancer did not appear to be a good indicator of mutation status, particularly for women whose age at first diagnosis is >40 years. Cancer 2009. © 2009 American Cancer Society.

4364: Direct intra-arterial (ophthalmic artery) chemotherapy with melphalan for advanced intraocular retinoblastoma: the Italian experience

ACTA OPHTHALMOLOGICA, Issue 2010
T HADJISTILIANOU
Purpose To report the preliminary results of the conservative treatment of advanced retinoblastoma (Stage Va e Vb) obtained with the melphalan protocol (direct intraarterial-ophthalmic artery infusion ). Methods 33 children (35 eyes) with advanced retinoblastoma who were eligible for enucleation were entered in phase two of one center open study-approved protocol of ophthalmic artery infusion of Melphalan to avoid enucleation (Italian Melphalan protocol, approved by the Ethic Commettee , University Hospital of Siena). Two cases have been treated bilaterally. 15 eyes were first diagnosis and 18 were relapses following chemo and/or radiotherapy. In two cases has not been possible to conclude the procedure due to haemodynamic problems. Results The ophthalmic artery was successfully cannulated in 35 eyes (total, 121 procedures). In 2 attempts was impossible to successfully conclude the procedure due to hemodynamic problems. Cannulation of the ophthalmic artery was performed by a femoral artery approach using microcatheters (magic 1.5) while the children were under general anesthesia and anticoagulated. Melphalan was infused into the artery over a 30-minute period (dose of 3-7 mg according to the age and size of the globe). Local and systemic toxicity have been evaluated and documented. Conclusion 33 children (35 eyes) with advanced retinoblastoma (Stage Va and Vb Reese classification) were eligible for the Melphalan Italian Protocol. The 78.7% of treated eyes is in complete remission. Superselective chemotherapy delivered through the ophthalmic artery can avoid enucleation, primary radiation or abuse of systemic chemotherapy.

Age-related penetrance of endocrine tumours in multiple endocrine neoplasia type 1 (MEN1): a multicentre study of 258 gene carriers

CLINICAL ENDOCRINOLOGY, Issue 4 2007
Andreas Machens
Summary Objective, In multiple endocrine neoplasia type 1 (MEN1), age-related tumour penetrance according to the type of MEN1 germline mutation has not been investigated in-depth. This study was conducted to examine whether carriers of out-of-frame/truncating and in-frame MEN1 mutations differ in age-related tumour penetrance. Design, A multicentre study with biochemical, hormonal and radiological screening for MEN1-associated tumours. Patients, A total of 258 MEN1 carriers from six major German tertiary referral centres averaging 43 years of age at last follow-up. Measurements, Main outcome measure was time to first diagnosis of MEN1-associated tumours. Results, Independent of the year of birth and observation period, time to first tumour diagnosis did not vary much by the type of MEN1 germline mutation or endocrine organ system, and perhaps not even by the type of endocrine tumour when the amount of time was considered by which the diagnosis probably has been advanced through the manifestation of hormonal symptoms. Parathyroid hyperplasia and adenomas developed almost twice as often as enteropancreatic and pituitary tumours (77%vs. 49,32%), and more than five to sevenfold as often as adrenal cortical tumours and carcinoids (77%vs. 15,10%), reaching penetrance rates of up to 90%, 60%, 40%, 26% and 17%, respectively. The heterogeneity of tumour penetrance was marked, ranging from 9 years to 25 years for the earliest, and from 68 years to 77 years for the latest tumour manifestation. Conclusions, Because of our inability of predicting tumour penetrance and malignant transformation individually, life-long follow-up of MEN1 carriers is warranted to prevent tumour morbidity.

Anastomotic leakage after curative anterior resection for rectal cancer: short and long-term outcome

COLORECTAL DISEASE, Issue 7Online 2010
C. A. Bertelsen
Abstract Objective, The influence of symptomatic anastomotic leakage (AL) after anterior resection (AR) for rectal cancer on short and long-term mortality and local and distant recurrence was analysed. Method, All patients with a first diagnosis of rectal carcinoma were prospectively registered in a national database. This comprised 1494 Danish citizens who had had a curative AR between May 2001 and December 2004. Data on survival and recurrence were obtained from the National Patient Register. Multivariate analyses were performed. Results, Anastomotic leakage increased the 30-day mortality [odds ratio (OR) 4.01 (95% CI 2.24,7.17)]. Of other possible risk factors, only age had a significant interaction with leakage, as the risk of death within 30 days of AR decreased with increasing age. Long-term survival decreased significantly after AL [hazard ratio (HR) of 1.63, CI 1.21,2.19]. A total of 97 (6.7%) and 258 (18.0%) patients had local and distant recurrence respectively in the follow-up period. The risk of local and distant recurrence after AL was not different with HR of 1.50 (CI 0.84,2.69) and 1.13 (CI 0.76,1.69) respectively. No other factors influenced the risk of recurrence due to AL. Conclusion, Anastomotic leakage after AR for rectal cancer increases the 30-day and long-term mortality, but AL did not increase the risk of local and distant recurrence. [source]
