RESUMO

Although antimony (Sb) contamination has been documented in urban areas, knowledge gaps remain concerning the contributions of the different sources to the Sb urban biogeochemical cycle, including non-exhaust road traffic emissions, urban materials leaching/erosion and waste incineration. Additionally, details are lacking about Sb chemical forms involved in urban soils, sediments and water bodies. Here, with the aim to document the fate of metallic contaminants emitted through non-exhaust traffic emissions in urban aquatic systems, we studied trace element contamination, with a particular focus on Sb geochemistry, in three highway stormwater pond systems, standing as models of surface environments receiving road-water runoff. In all systems, differentiated on the basis of lead isotopic signatures, Sb shows the higher enrichment factor with respect to the geochemical background, up to 130, compared to other traffic-related inorganic contaminants (Co, Cr, Ni, Cu, Zn, Cd, Pb). Measurements of Sb isotopic composition (δ123Sb) performed on solid samples, including air-exposed dusts and underwater sediments, show an average signature of 0.07 ±â€¯0.05‰ (n = 25, all sites), close to the δ123Sb value measured previously in certified reference material of road dust (BCR 723, δ123Sb = 0.03 ±â€¯0.05‰). Moreover, a fractionation of Sb isotopes is observed between solid and dissolved phases in one sample, which might result from Sb (bio)reduction and/or adsorption processes. SEM-EDXS investigations show the presence of discrete submicrometric particles concentrating Sb in all the systems, interpreted as friction residues of Sb-containing brake pads. Sb solid speciation determined by linear combination fitting of X-Ray Absorption Near Edge Structure (XANES) spectra at the Sb K-edge shows an important spatial variability in the ponds, with Sb chemical forms likely driven by local redox conditions: "dry" samples exposed to air exhibited contributions from Sb(V)-O (52% to 100%) and Sb(III)-O (<10% to 48%) species whereas only underwater samples, representative of suboxic/anoxic conditions, showed an additional contribution from Sb(III)-S (41% to 80%) species. Altogether, these results confirm the traffic emission as a specific source of Sb emission in surface environments. The spatial variations of Sb speciation observed along the road-to-pond continuum likely reflect a high geochemical reactivity, which could have important implications on Sb transfer properties in (sub)surface hydrosystems.

RESUMO

Type 1 diabetes mellitus (T1DM) is associated with a high risk of cardiovascular (CV) complications, even after controlling for traditional CV risk factors. Therefore, determinants of the residual increased CV morbidity and mortality remain to be discovered. This prospective cohort of people living with T1DM in France (SFDT1) will include adults and children aged over six years living with T1DM, recruited throughout metropolitan France and overseas French departments and territories. The primary objective is to better understand the parameters associated with CV complications in T1DM. Clinical data and biobank samples will be collected during routine visits every three years. Data from connected tools, including continuous glucose monitoring, will be available during the 10-year active follow-up. Patient-reported outcomes, psychological and socioeconomic information will also be collected either at visits or through web questionnaires accessible via the internet. Additionally, access to the national health data system (Health Data Hub) will provide information on healthcare and a passive 20-year medico-administrative follow-up. Using Health Data Hub, SFDT1 participants will be compared to non-diabetic individuals matched on age, gender, and residency area. The cohort is sponsored by the French-speaking Foundation for Diabetes Research (FFRD) and aims to include 15,000 participants.

RESUMO

PURPOSE: Although one in three patients with diabetes in Western countries is over 70 years-old, geriatric syndromes and their relationship with survival remain seldom studied. The present aim of the GERODIAB study was to examine the evolution of geriatric disorders and their relationship with survival in older type 2 patients with diabetes with initial sufficient autonomy. METHODS: We performed a prospective, observational study over 5 years in patients with diabetes aged 70 years or above. A total of 987 consecutive type 2 patients with diabetes (mean age 77 years, range 70-94 years, 65.2% were 75 years and above, 52.1% women) were included from 56 French diabetic centres. Individual characteristics, diabetes parameters and geriatric parameters (autonomy, nutrition, cognitive alteration, depression, orthostatic hypotension, falls) were annually recorded. Survival was analysed using the Kaplan-Meier method and proportional hazards regression models. RESULTS: Institutional living, impaired activity and difficulties in instrumental daily activity, cognitive disorders, malnutrition, depression, orthostatic hypotension and hypoglycaemia strongly increased during the follow-up. Institutional living, impaired activity and difficulties in instrumental daily activity, cognitive disorders and hypoglycaemia were strongly associated with reduced survival, but not falls. In hazard ratio models, living in an institution (HR = 2.39; CI = 1.77-3.24; p < 0.0001) and impaired Activity of Daily Living scale score were the most significant and independent predictors of death (HR = 1.59; CI = 1.19-2.13; p = 0.0016), associated with HbA1c ≥ 70 mmol/mol (HR = 1.62; CI = 1.12-2.36; p = 0.011). CONCLUSION: Our findings show the considerable alteration of geriatric parameters and their relationship with decreased survival after a 5-year follow-up in type 2 patients with diabetes, independent of HbA1c and age. They, therefore, confirm the prognostic interest of using yearly geriatric markers in older diabetic patient management, especially the ADL, IADL and MMSE scales. Taking into account these prognostic parameters should contribute to target appropriate HbA1c goals. TRIAL REGISTRATION: Registered at clinicaltrials.gov (21/01/2011): NCT01282060.

RESUMO

G6PD deficiency is very frequent with almost 400 millions of patients worldwide in Asia, Africa and Mediterranean. G6PD deficiency is involved in mild or severe haemolysis and the precipitating factor is usually a drug. More than 100 drugs have been implicated and fluoroquinolones are one of the more classic. However, the literature review shows that only a few observations have been clearly documented.

RESUMO

Bourneville tuberous sclerosis is a phacomatosis characterized by skin, neurological and ophthalmological lesions. At first, seizure can reveal cerebral lesions, but other causes may be suspected. We report a case of a Bourneville tuberous sclerosis in a 41-year-old-man with hypoglycemia leading to seizures, resulting from an insulinoma.

RESUMO

UNLABELLED: Multicentric registers such as The French Acromegaly Register provide data on rare disorders that are otherwise difficult to obtain, so avoiding extrapolation from limited data sets. This study focuses on clinical, hormonal and therapy characteristics of acromegaly in people over 70 years old. The objective was to compare this population with the youngest to disclose if the medical management was similar. PATIENTS AND METHODS: The data were obtained from the 30 centres that have registered patients in the Acromegaly Register since 1999. RESULTS: The register listed 644 acromegaly patients on 1st January 2005, of whom 68 (22 men and 46 women) were over 70 years old, independently of the diagnosis date of their disease. Their average age was 76.8 + or - 5 years (range: 70-95) and they had suffered from acromegaly for 11 + or - 6 years (compared to 7 years in those aged less than 70). Their BMI were similar. Diabetes and hypertension were more frequent than in younger acromegalic patients and in the general French population matched for age. Circulating GH and IGF-1 concentrations were lower than in the younger acromegalic patients on inclusion and 1 year after treatment. There was no significant difference in the tumor size. Only 44% of the patients over 70 underwent surgery, against 90% of patients under 70 years. However, the fractions of young and elderly patients with a controlled disease 1 year after inclusion were the same (51%). CONCLUSION: In the limits of the use of register, these data reveal a high prevalence of diabetes and hypertension in the eldest acromegalic patients. Despite much less frequent surgical intervention, patients' disease under control is equivalent to the younger population 1 year after the initial interview, confirming the effectiveness of the choices of treatment.

RESUMO

UNLABELLED: All diabetes specialists are aware of the frequency and severity of coronary disease in diabetics. Non-invasive diagnostic tests perform well, but they could be better. AIM: To assess the role of computed tomographic coronary angiography in diabetics. New cardiac imaging techniques such as CT coronary angiography are promising tools for the selection of patients for conventional X-ray coronary angiography, which remains the key for diagnosis and angioplasty. The limitations of CT coronary angiography, even using the most advanced machines with a 64-slice capacity, are its resolution, the need for an iodine contrast agent and the cumulative radiation from repeated examinations. CONCLUSION: CT coronary angiography appears to have great potential for patients at risk where non-invasive tests cannot absolutely exclude coronary disease and for the follow-up of coronary bypass surgery.

RESUMO

INTRODUCTION: Hypercalcemia is a rare complication of non-Hodgkin lymphoma. Usually, hypercalcemia occurs late in the disease course, except for high-grade lymphoma. Most often hypercalcemia is related to excessive level of circulating PTH-rP or sometimes, 1,25(OH)2D3. Concomitant high plasmatic concentration of PTH-rP and 1,25(OH)2D3 is uncommon. EXEGESIS: We report the case of a 82-year-old man who presented with abdominal pain and weight loss, leading to the diagnosis of diffuse large-B-cell lymphoma (high-grade lymphoma) associated with symptomatic hypercalcemia (3.21mmol/l). PTH-rP and 1,25(OH)2D3 plasmatic levels were high. Calcium concentration was normalized with glucocorticoids and sequential chemotherapy. CONCLUSION: This case report confirms that hypercalcemia, as consequence of excessive plasmatic level of PTH-rP secreted by tumoral cells, can occur early in the course of high-grade lymphoma. Glucocorticoids and chemotherapy are the best treatment options.

RESUMO

The disorder now known as metabolic syndrome has been recognized for 50 years, but its multiple definitions have led to some confusion and even doubt about its very nature. Metabolic syndrome is directly linked to the presence of android obesity, which indicates insulin resistance and lies at the root of all risk factors and early indications of type 2 diabetes. It is diagnosed by systematic measurements of waist size and its direct interpretation taking ethnic origin into account. This pragmatic approach avoids the uncertainties generated by differing definitions and is subtler than the presence or absence of metabolic syndrome in a given patient. Drug-free treatment of an android obese patient is inexpensive and effective, but this apparently simple approach masks difficulties of application. However, these are sociological problems.

RESUMO

UNLABELLED: Multi centre registries such as the French Acromegaly Registry created in 1999 provide data on rare disorders that are otherwise difficult to obtain. This study focuses on the characteristics of high blood pressure in people aged of over 70 years old. PATIENTS AND METHODS: The data were obtained from the thirty centres where patients had been recorded on the Acromegaly Registry since 1999. RESULTS: The Register listed a total of 644 patients with acromegaly at January 1st 2005, of whom 68 (22 men and 46 women) were aged over 70 years old (10.6%). Their mean age was 76.8 +/- 5 years (range 70 - 95) and they had been presenting acromegaly for 11 +/- 6 years (compared to 7 years in those aged less than 70). Their BMI were 27.9 +/- 4 kg/m2 for men, 27.7 +/- 4 for women (respectively 28.4 +/- 4.3 and 26.7 +/- 4.4 in those aged less than 70 years). Hypertension was particularly frequent in this population, reaching 80% vs. 27% under 70 years (p=0.0001). Prevalence was then higher than in general population (referring to FLAHS study). Mean blood pressure was 143 +/- 12 / 84 +/- 15 mmHg for men and 141 +/- 17 / 79 +/- 9 for women. 46% of men and 30% of women treated or not, had blood pressure over 140 / 90 mmHg. Data showed 12% of arrhythmic cardiopathy, 8% of cardiac insufficiency, 12% of ischemic cardiopathy and 12% of patients suffering from arteritis or stroke. Although various therapeutic strategies had been applied for young and elderly patients, 51% in each group were in remission one year after inclusion. DISCUSSION: More than 10% of patients are aged over 70 years in the French Acromegaly Registry and hypertension is very frequently observed in this population. The increasing life expectancy due to currently available treatments justifies a strict management of patients in order to reduce cardiovascular risks, which stay the main cause of morbidity and mortality.

RESUMO

UNLABELLED: The new recommendations of the French national authority for health (or Haute Autorité de Santé: HAS) concerning management of high blood pressure (HBP) deserve to be compared with real clinical practices in a large population. MATERIAL AND METHODS: [corrected] EPIMIL is a prospective epidemiological study designed to assess the prevalence of the metabolic syndrome and the risk factors in a 2045 French male military personnel coming from Paris area. The different recommendations of the HAS have been applied to these subjects, and the aim of this work is to compare these theoretical objectives to what is done in real practice. RESULTS: Among these 2045 subjects aged of mean 38,6 +/- 8,8 years, 78 (4%) are known and treated for HPB. Although half of them present more than two associated risk factors, the means of systolic blood pressure and diastolic blood pressure stay at high levels. The blood pressure (BP) targets established at 140/90 mmHg are only reached by 33 patients (42%). Among the 1967 subjects considered to have normal BP, the BP considered as optimal (120/80 mmHg) is only found in 695 subjects (35.3%) and 428 (21.7%) do present ignored or neglected HBP, in spite of the presence of important associated risk factors. Then, the cardiovascular risk stratification into levels, as recommended by the HAS, shows that for these subjects considered to have normal BP, risk is finally low for 6%, moderate for 12%, and high for 3.5%. COMMENTS: In a selected and in theory regularly followed population, the recommendations of the HAS are insufficiently applied, as well for detection or treatment of HBP. Then, information of both medical personnel and also the interested parties should be necessary, in order to see these recommendations applied in real practice.

RESUMO

UNLABELLED: The aim of this study was to assess the responsibility of night-time blood pressure in the onset of nephropathy in diabetic patients. PATIENTS AND METHODS: This study included 98 diabetic patients (mean age: 54 +/- 15 years, diabetes duration: 15 +/- 10 years). An evaluation of diabetes and a 24-h ambulatory blood pressure were performed at the initial evaluation (Y0) and about five years later (Y5). At Y0, all patients had normal urinary albumin excretion (UAE) (<30 mg/24h). They were separated into two groups according to urinary albumin excretion at Y5: group (N +): UAE>30 mg/24h and group (N-): UAE<30 mg/24h. Twenty four hours ambulatory blood pressure, clinical and biological parameters recorded at Y0 were compared in both. RESULTS: At Y5, there was 18 patients in group (N +) and 78 in group (N-). Patients of group (N +) were older than those of group (N-): 62.9 +/- 9.5 vs. 52.6 +/- 15.7 years, p<0.01, and their BMI was higher (28 +/- 5 vs. 25 +/- 4 kg/m2, p<0.03). Diabetes duration and Hb A1c levels did not differ from significant manner in both. At Y0, UAE was significantly higher in group (N +) than in group (N-): 13 +/- 7 vs. 8 +/- 6 mg/24h, p<0.01. At the initial evaluation, daytime systolic and diastolic blood pressures did not differ from significant manner in both. Systolic and diastolic BP night-time were higher in diabetic patients who developed microalbuminuria (SBP: 122 +/- 19 vs. 113 +/- 13 mmHg, p<0.05 and DBP: 70 +/- 6 vs. 65 +/- 10 mmHg, p<0.03). UAE collected at Y5 was correlated to night-time BP recorded at Y0 (SBP: r=0.381, p=0.001 and PAD: r=0.294, p=0.004) and night-time systolic BP explained 12.3% of the UAE variance. Progression of UAE between the two evaluations was found to be correlated to the night-time systolic BP recorded at Y0 (r=0.335, p=0.0008) and night-time systolic BP explained 11.7% of the progression variance. There was a negative correlation between UAE at A5 and the difference between daytime and night-time BP recorded during the same evaluation (r=- 0.230, p=0.024 with SBP and r=- 0.243, p=0.017 with DBP). CONCLUSION: The results underlign the resposability of night-time blood pressure, and more especially of nighttime systolic blood pressure, for the onset of nephropathy in diabetic patients.

RESUMO

UNLABELLED: The purpose of this study was to assess the blood pressure modifications in type 1 diabetic patients who present reduction of heart rate variability. PATIENTS AND METHODS: This study included 70 type 1 diabetic patients (mean age: 42 +/- 13 years, diabetes duration: 13.2 +/- 9 years. They were free for complications and did not receive other treatment than insulin. Heart rate variability was evaluated using 24-h continuous ECG record spectral analysis. Patients were divided into two groups according to whether log high frequency power was lower (group 1, N=36) or higher (group 2, N=3 4) than 70 patients'mean. Clinical and biological features and 24-h ambulatory blood pressure measurement were compared in both groups. RESULTS: Patients of group 1 were older than group 2 (47.8 +/- 11.2 vs. 35.7 +/- 12.2 years, p<0.0001) and diabetes duration was higher (16.9 +/- 8.4 vs. 9.4 +/- 8 years, p<0.001). BMI and Hb A1c did not differ from significant in both. Night-time blood pressure was upper in group 1 (SBP: 112 +/- 13 vs. 103 +/- 11 mmHg, p<0.01 and DBP: 66 +/- 8 vs. 60 +/- 7 mmHg, p<0.001). The difference between blood pressures during day and night (DeltaBP) were lower in group 1 than in group 2 (DeltaSBP: 10 +/- 9 vs. 15 +/- 7 mmHg, p<0.02 and DeltaDeltaBP: 9 +/- 7 vs. 12 +/- 5 mmHg, p<0.04). DSBP and DDBP were found to be correlated with log HF power (r=0.356, p<0.003), which could explain 11.8% and 12% of their variance. Urinary albumin excretion rate was higher in group 1 (8 +/- 4 vs. 5 +/- 3 mg/24h, p<0.01). CONCLUSION: In type 1 diabetic patients free for complications, reduction in heart rate variability linked to age and diabetes duration is associated with a reduction in nighttime BP fall. These two parameters of autonomic neuropathy could have a pathogenic role in the development of incipient nephropathy.

RESUMO

PURPOSE: Nelson's syndrome is a severe complication of bilateral adrenalectomy performed in the treatment of some Cushing's diseases, and its management remains difficult. Trough the observation of a patient suffering from a severe form of Nelson's syndrome for more than 10 years, the authors review the literature and discuss the main current therapeutic possibilities. CURRENT KNOWLEDGE AND KEY POINTS: Many molecules have been used with variable results. In our observation cabergoline at 2 mg per week seems to be efficient after a 3 and a half years follow-up, in accordance with some recent publications. More than bromocriptine, this dopamine agonist provides interesting prospects for this disease's management. Moreover, if the conventional treatments as valproic acid or cyproheptadine are not very efficient, somatostatin analogs seem to be of some therapeutic interest. FUTURE PROSPECTS AND PROJECTS: New molecules are currently evaluated, but studies are difficult to conduct because of the low disease prevalence. Tumour receptors analysis undoubtedly constitutes an attractive way to find new therapeutic targets.

RESUMO

While hypothyroidism secondary to treatments by lithium are well known, cases of hyperthyroidism are less common. A 48 years old patient under lithium carbonate from about 10 years ago presents hyperthyroidism without any auto-immunity biological markers, associated with a very low thyroid tracer uptake on scintigraphy. Treatments by anti thyroid agents will be necessary during months in order to normalize the hormone level, whereas lithium is maintained. Only few tens of cases of hyperthyroidism related to lithium have been reported in the literature. This observation shows the importance of the thyroid hormonal follow up for patients under lithium, in order to treat them before the outbreak of a thyroid dysfunction. The causal toxic mechanism is still unclear, and may be related with a direct damage of lithium to follicular cells.

RESUMO

INTRODUCTION: Healthy pets contact are able to induce unusual and severe diseases. CLINICAL CASE: This case reports the medical history of a dorsal spondylodiscitis in a diabetic patient admitted for a chronic wound of his toes. He had a long-standing history of regular consumption of alcohol and tobacco. Blood bottles and biopsy of intervertebral disc infected discovered Pasteurella dagmatis, commonly colonizing the oropharynx of healthy dogs and cats. In this case, licking of his injured toe by his dog was the likely source of entry of the organism. DISCUSSION: We found no identical cases in the medical literature. Diabetes mellitus and other immunocompromised disorders justify to change behaviours toward domestic animals.

RESUMO

CONTEXT: The Metabolic syndrome is considered to be an important public health problem, but few epidemiological studies have defined the present situation in France. EPIMIL is a prospective epidemiological study that began on February 1, 2003. SUBJECTS AND METHODS: This study was designed to identify the clinical and laboratory parameters of metabolic syndrome and cardiovascular risk factors in a population of 2045 male military personnel based in the Paris region. The initial 1-year cross-sectional study will be followed by a 10-year follow-up and patient care. RESULTS: The 2045 subjects included 185 (9%) presented at least 3 of the 5 NCEP ATP III criteria defining metabolic syndrome. They were significantly older (42.2 +/- 8.5 yrs) than the other subjects (37.3 +/- 8.7 yrs, P<0.001), had a higher BMI (29.5 +/- 3.4 vs 24.8 +/- 2.9 kg/m2, P<0.001) and a greater body weight at age 20 (75.4 +/- 11 vs 70.4 +/- 8.5 kg, P<0.01). Smoking, little physical activity and family histories of diabetes and arterial hypertension were more frequent in these men. While levels of the cholesterol and CRP us were higher, Lp(a) and homocysteine concentrations were normal. Plasma insulin and BMI (r = 0.456 P<0.0001) and plasma insulin and waist circumference (r = 0.446 P<0.0001) were well correlated. Lastly, plasma insulin, free fatty acids and cardiovascular risk increased steadily with the increase in the number of metabolic syndrome criteria. CONCLUSIONS: These results in a large and particularly uniform population of men show the prevalence of metabolic syndrome in adult men, and demonstrate its link with insulin resistance. Men with several risk factors require specific care, particularly for hypertension and dyslipidemia; the effectiveness of this care will be evaluated during the follow-up period.

RESUMO

INTRODUCTION: Metabolic syndrome is a cardiovascular risk factors cluster and hyperhomocysteinemia an obvious independant risk factor. OBJECTIVE: To ascertain if hyperhomocysteinemia is associated with the metabolic syndrome. METHODS: "Epimil" is a prospective epidemiologic survey, which began by a cross-sectionnal study of cardiovascular risk factors in a French population, which then will be followed for ten years for supervision and intervention. Initial data collection, blood pressure measurement, ECG and blood samples (biology and DNA) have been performed. For the metabolic syndrome, we used the criterias of the third report of the national cholesterol education program expert panel on detection, evaluation, and treatment of high blood cholesterol in adults (NCEP ATP III). RESULTS: Out of 2045 men aged from 20 to 58 years (37.7+/-8.7 years), 185 (9%) have metabolic syndrome (at least three criterias), 587 (29%) a blood homocysteine>or=12 micromol/L and 202 (10%)>or=15 micromol/L. Homocysteinemia is 10.97+/-5.01 micromol/L for the whole population and doesn't differ with (11.4+/-6 micromol/L) or without (10.9+/-5 micromol/L) the metabolic syndrome, as does its values distribution. It's not correlate with the body mass index, waist and hip measurements, nor with glycemia, HbA1c, insulin resistance and cardiovascular risk markers (CRPus, microalbuminuria). It weakly correlates with systolic and diastolic blood pressure, creatinine clearance, tobacco use, cholesterolemia, triglycerides and free fatty acids but not with HDL and LDL fractions, nor lipoprotein (a). Among this population, it slightly contributes to the ten years vascular risk evaluated according to Framingham equations or Score system. CONCLUSIONS: Homocysteinemia and the prevalence of hyperhomocysteinemia don't differ with or without the metabolic syndrome and doesn't correlate its main criterias.

RESUMO

INTRODUCTION: Imaging of the pancreas soon after diagnosis of diabetes can help screen for tumors. CASE: A 45 year-old man with recently diagnosed insulin-dependent diabetes and no other notable history was found to have intraductal papillary mucinous tumour of the pancreas (IPMTP), a month after an unexplained and benign acute pancreatitis. DISCUSSION: The histology of IPMTP differs from that of the adenocarcinomas usually described in these circumstances, and they are far rarer. Because they carry the risk of malignant degeneration, early diagnosis is important. Surgery is the only curative treatment and should therefore be discussed.
