Article: [Multidrug intoxication].
[show abstract] [hide abstract]
ABSTRACT: The authors report an suicide attempt by a 43 years old woman treated by Previscan, Effexor, Rivotril, and Stilnox for phlebitis anteriority and anxious-depressive disorders. On arrival to the emergency unit, the medical status and the patient history required a cardiovascular reanimation and gastric washing. The haemostasis analysis demonstrates an anticoagulant overdose and the prescription of vitamine K1 and PPSB was necessary. Later, the multidrug poisoning was demonstrated thanks to blood, urinary and gastric fluid high performance liquid chromatography toxicological analyses. This case report points out that biological and toxicological analyses are complementary. The first ones are useful to determine the emergency symptomatic cares, and to check the drugs' efficiency. The second ones, although longer, are necessary to identify with certainty incriminated drugs.Annales de biologie clinique 04/2009; 67(2):227-32. · 0.34 Impact Factor -
Article: [Clinical and biological monitoring of nutritional status in severe burns].
[show abstract] [hide abstract]
ABSTRACT: Burn patients are subject to hypermetabolism and catabolic states. Aim was to evaluate our current practice in nutrition. Twenty-one severely burned patients were prospectively included during three months period. Body weight was measured at least two times in a week during all stay in burn ICU. Biological markers of inflammation (C-reactive protein, CRP) and nutrition (prealbumin) were performed weekly. Protocol included early nasogastric feeding, tolerated gastric stasis less than 250 mL at four hours nasogastric aspirations, caloric target value of 40 Kcal/kg per day and measurement of total daily calorie intakes. Patient demographics showed a mean percent total body surface burn of 51.1+/-27 % (range 20-90), age of 38.7+/-13.1 years (range 18-67) and 57.3 % of smoke inhalation. All patients were ventilated and 19 patients survived. Length of stay was 75.7+/-47 days (range 22-184). Patients received only 58.9+/-10 % of calorie intakes recommended by French burn society. Loss of body mass was 15.2+/-9 kg (range 3-31) or 19.1+/-10 % of admission weight (range 5-37). Erosion of body mass was not correlated with burned surface (p=0.08), calorie intakes (p=0.26), smoke inhalation (p=0.46), lengths of stay (p=0.53), lengths of ventilation (p=0.08) or nutrition (p=0.12), days of antibiotic (p=0.72), number of dressing changes (p=0.6) or surgery (p=0.64). Biological parameters showed CRP decreasing and prealbumin improving values. New strategies of nutrition are necessary to improve outcome and reduce body mass loss in burns.Pathologie Biologie 06/2008; 57(7-8):524-9. · 1.53 Impact Factor -
Article: [Determination of ciprofloxacin in human serum by high-performance liquid chromatography].
[show abstract] [hide abstract]
ABSTRACT: A high-performance liquid chromatography method was developed for the rapid determination of ciprofloxacin in human serum. After protein precipitation, chromatographic separation of ciprofloxacin in plasma was achieved with an octyl column and 20 mmol/L phosphate buffer, methanol and acetonitrile 76/12/12 (v/v/v), pH 4, as mobile phase. Quantitative determination was monitored on a fluorescence detector using an excitation and emission wavelength of 278 and 450 nm, respectively. Enrofloxacin was used as internal standard. Calibration curve is linear over the range 0,12 to 20 microg/mL (r=0,9992). Limit of detection and limit of quantification are 0,04 and 0,12 microg/mL, respectively. Within-day coefficient of variation (2,0 to 3,1 %) and day-to-day coefficient of variation (4,3 to 5,5 %) at three different concentrations are sufficient. Relative recovery ranged from 91,1 to 94,0 % at three different concentrations. Each analysis requires no longer than 7 min.Annales de biologie clinique 63(5):513-6. · 0.34 Impact Factor -
Article: [Acute methanol poisoning: about one case].
[show abstract] [hide abstract]
ABSTRACT: In this article, we report a case of metabolic coma with acidosis and elevated anion gap. The etiological investigation requires laboratory findings because clinical features are not enough specific in the early stage of intoxication. Measurement of methanol and formic acid, its toxic metabolite, is useful in confirming the diagnosis. The major differential diagnosis to discuss is ethylene glycol poisoning. Methanol poisoning is rare but potentially fatal; the toxicity of methanol is clearly correlated to the degree of metabolic acidosis. Formic acid accumulation is also associated with an increased risk for ocular and neurologic dysfunction. For preventing permanent visual damage, the acidosis should be corrected by antidotal treatment or haemodialysis in severe poisoning.Annales de biologie clinique 63(5):556-60. · 0.34 Impact Factor -
Article: [Diagnosis of adult-onset Still's disease: contribution of biology].
[show abstract] [hide abstract]
ABSTRACT: We report one case of adult-onset Still's disease. The diagnosis of this disease currently requires application of Yamaguchi's criteria and then exclusion of infectious, haematological, autoimmune and neoplasic disorders. The place of biology is enhanced with the use of new markers like ferritin and glycosylated ferritin. Low percentage of glycosylated ferritin (<20%) in presence of very high level of ferritin, unexplained prolonged fever with leukocytosis can help to diagnosis. However, glycosylated ferritin is not yet of in routine use.Annales de biologie clinique 65(3):303-7. · 0.34 Impact Factor -
Article: [A young woman with severe hyponatremia].
[show abstract] [hide abstract]
ABSTRACT: We report here the case of a young woman, who came by herself at the emergency department, presenting with a severe hyponatremia (106 mmol/L), as shown by her initial biological report. The biological comment leads us to review the hyponatremia considering on one hand osmolarity and on the other hand volemia. Patient's tests results showed hyponatremia with hypoosmolarity and isovolemia, due to her potomania. At last, the authors expose the main guidelines for the correction of hyponatremia.Annales de biologie clinique 62(5):563-7. · 0.34 Impact Factor -
Article: [Coma in type 2 diabete mellitus on metformin treatment].
[show abstract] [hide abstract]
ABSTRACT: Non traumatic coma in diabete mellitus has two origins : hypo- or hyperglycemia. Coma with hyperglycemia can be due to ketoacidosis, hyperosmolar state or lactic acidosis. The present observation reports on a type 2 diabete mellitus patient presenting with a coma while the patient was on metformin and glibenclamide treatment. On admission, biologicals tests showed major acidosis, hyperglycemia and hyperosmolarity. No metformine accumulation was demonstrated by analytical measure. In this case, the association of hyperosmolar state and metabolic acidosis prove the difficulty of the differential diagnosis.Annales de biologie clinique 61(1):84-7. · 0.34 Impact Factor -
Article: [Interference of hydroxocobalamine treatment on commun biochemical determinations].
[show abstract] [hide abstract]
ABSTRACT: Hydroxocobalamin, antidote of the cyanide poisoning, is a red and water soluble pigment, which colors biological mediums. The interferences caused by this molecule are studied for plasma pools overloaded with hydroxocobalamin for concentrations from 0 to 1,125 mg.L-1. The results of 16 biochemical parameters on Vitros 750 XRC (Ortho-clinical Diagnostics) and of 23 biochemical parameters on Cobas Integra 700 (Roche Diagnostics) are examined. With this analytical system, unconjugated and conjugated bilirubin, creatinin, and CK results are changed as soon as plasma concentration of hydroxocobalamin reachs 124 mg.L-1. For the Vitros 750 XRC, ASAT, iron, creatinin, phosphorus are more sensitive to this interference. But, other results are changed for the two analytical systems for superior hydroxocobalamin concentrations.Annales de biologie clinique 60(1):57-64. · 0.34 Impact Factor -
Article: [Evaluation of the Unicel DXC 600 (Beckman Coulter) and comparison with Integra 800 (Roche Diagnostics)].
[show abstract] [hide abstract]
ABSTRACT: The Unicel DXC 600 is an automated analytical system from Beckman Coulter for measuring usual biochemistry parameters (electrolytes, substrates and enzymatic activities), therapeutic drugs, drugs of abuse and specific proteins. According to the "Société française de biologie clinique (SFBC)" validation protocol, we tested the following parameters: electrolytes (sodium, potassium, chloride, total CO2), substrates (uric acid, calcium, phosphate, glucose, creatinine, urea, cholesterol, HDL cholesterol, bilirubin, iron, triglycerides), enzymes (ALAT, ASAT, amylase, CK, GGT, LDH, lipase, ALP), total proteins and specific proteins (albumin, CRP, haptoglobin). The results confirm the excellent analytical performances regarding imprecision. The comparison study shows differences between values obtained with Unicel DXC 600 and Integra 800 (Roche diagnostics), leading to the use of correcting factors for some parameters.Annales de biologie clinique 65(5):555-62. · 0.34 Impact Factor -
Article: [A "pulseless" woman with proteinuria!].
[show abstract] [hide abstract]
ABSTRACT: Takayasu arteritis, also called pulseless women disease, is a chronic vasculitis of unknown aetiology, which primarily involves the aorta, its branches and coronary and pulmonary arteries. It is an uncommon disease with a variety of presentations and most frequently found in Asia than in Europe. We report a case of a 52-year-old woman, suffering from Takayasu arteritis for 19 years. She was admitted to the hospital for diffuse pain and oedema. Biological tests pointed out proteinuria with renal failure, which was confirmed by a renal biopsy. The association of Takayasu arteritis and renal failure is unusual. This review focuses on the biological manifestations of Takayasu arteritis and on the link between this disease and the renal failure observed in this case.Annales de biologie clinique 62(4):441-5. · 0.34 Impact Factor -
Article: [Exertional heat stroke: biological survey interest].
[show abstract] [hide abstract]
ABSTRACT: We present a 27-year-old soldier exertional heat stroke case report. Clinical examination has been reassuring during hospitalization. However biological disorders, especially liver and haemostasis disturbances, show off exertional heat stroke is a serious pathology on which clinician and biologist attention must be focalized, even if evolution is the more often favourable when an adapted and rapid treatment is used.Annales de biologie clinique 67(3):333-7. · 0.34 Impact Factor
