In a retrospective auxological study of 145 patients seen in Belgium during a 9-year period for treatment of precocious puberty, 28% appeared to be foreign children (39 girls, one boy) who immigrated 4 to 5 years earlier from 22 developing countries, without any link to a particular ethnic or country background. The patients were either adopted (n = 28) or non-adopted (n = 12), the latter having normal weight and height at immigration and starting early puberty without evidence of earlier deprivation. This led to the hypothesis that the mechanism of precocious puberty might involve previous exposure to oestrogenic endocrine disrupters. A toxicological plasma screening for eight pesticides detected p,p'-DDE, which is derived from the organochlorine pesticide DDT. Median p,p'-DDE concentrations were respectively 1.20 and 1.04 ng/ml in foreign adopted (n = 15) and non-adopted (n = 11) girls with precocious puberty, while 13 out of 15 Belgian native girls with idiopathic or organic precocious puberty showed undetectable concentrations (<0.1 ng/ml). A possible relationship between transient exposure to endocrine disrupters and sexual precocity is suggested, and deserves further studies in immigrant children with non-advanced puberty. [less ▲]

Controversy still exists concerning the proper daily dose of methadone to be used in opiate dependency treatment. Because it is admitted that serum methadone concentration may be significantly correlated with the amount of drug available at the receptor level, it could be interesting to predict the methadone daily doses necessary to reach such a serum concentration. The authors have attempted to correlate the serum methadone level with the daily intake, considering the metabolic activity of the patients. A poor correlation was found between methadone doses and methadone serum concentrations (r2 = 0.0409, p = 0.048). The test used to determine the metabolic activity of patients is the 6-OH cortisol/17-OH corticosteroids ratio in urine. This urinary 6-OH cortisol/17-OH corticosteroids ratio was tested because cortisol is metabolized through the same P450 cytochromes as methadone, namely cytochrome P450 3A4. This determination could be of interest because it could be tested before methadone administration to predict optimal doses. But when the authors tried to correlate the methadone serum concentration with the steroid ratio, they failed to find a significant correlation (r2 = 0.0046, N.S.), even when they took into account the daily doses (r2 = 0.0015, N.S.), most probably because of some limitations of the cortisol ratio.

The relationship between clinical effects and plasma concentrations of citalopram, fluoxetine, clomipramine, paroxetine and venlafaxine was studied in 119 cases of major depression. Clinical effects were evaluated using the Clinical Global Impression (CGI) improvement scale. Antidepressants were quantified by a separative chromatographic methodology. Plasma concentrations in responder patients were compared with the plasma concentrations proposed in literature as effective values. We found that the usual therapeutic window is convenient for citalopram and clomipramine, but could be reduced for fluoxetine and increased for venlafaxine and paroxetine. Concurrent drug interactions were also evaluated and clomipramine or citalopram plasma levels were found to be influenced by the presence of associated drugs. A larger study is needed, taking into account not only plasma concentrations and clinical effects, but also some pharmacokinetic data, especially the metabolic activity characterising the patient, and the presence or not of associated drugs.

We evaluated the performance of the Emit® tox benzodiazepine and barbiturate assays (Dade Behring) and fluorescence polarisation immunoassay (FPIA) (Abbott) for use with serum determinations in preliminary therapeutic drug monitoring or acute drug intoxication detection. Performance, as indicated by CVs, of the Emit® tox benzodiazepine and barbiturate assays and FPIA showed that both immunochemical techniques are precise and have good reproducibility. For within-run studies, results from benzodiazepine determinations showed maximum CV values of 1.91% for the Emit® method and 2.65% for FPIA; results from barbiturate determinations showed maximum CV values of 2.01% for the Emit® method and 1.89% for FPIA. For between-run studies, results from benzodiazepine determinations showed maximum CV values of 1.79% for the Emit® method and 1.12% for FPIA; results from barbiturate determinations showed maximum CV values of 2.09% for the Emit® method and 2.02% for FPIA.

Drug monitoring of anticancer chemotherapies.Drug doses used in anticancer treatments are mostly calculated by the use of clinical criteria, sometimes by using nomograms providing a posology based on the body surface area (BSA) but rarely by taking into account classical pharmacokinetic parameters, as usually for optimizing the treatment with other pharmaceutical classes of drugs (antibiotics, antiepileptics,…). Because the narrow therapeutic index and important intra- and interindividual variations of the pharmacokinetic parameters, anticancer drugs could constitute a pharmacological class for which the posology could be defined by a classical therapeutic drug monitoring. Of course, the determination of the plasmatic level of anticancer drug does not always permit to predict their pharmacological efficacy and toxicity. To reach it, it is necessary to calculate the area under the curve obtained on base of several blood concentrations. [less ▲]

Cyanide is a highly toxic poison, able to very rapidly induce the death. Thiocyanate anion (SCN-) is a metabolic product of cyanide and cyano-containing organic substances, produced by two major enzymes : thiosulfate sulfure transferase and β mercaptopyruvate transsulfurase. Determinations of blood cyanide is important to confirm the diagnostic of intoxication. A survey of methods for the quantitative determination of cyanide and thiocyanate in biological matrices is presented. Particular attention is paid to the rapidity and to the sensitivity of the method. [less ▲]

Reduced vitamins K are acting as cofactors of glutamic carboxylation of procoagulant factors (II, VII, IX and X). The reduction of these vitamins is inhibited by oral anticoagulants. The response to antivitamins K is individual and may change during the treatment of a patient. The determinations of plasmatic vitamin K and acenocoumarol may help to explain the mechanism of a resistance to the anticoagulant therapy. Quantifications of vitamin K1 are realized after liquid-liquid extraction with liquid chromatography and fluorescence detection after post-column reduction. For acenocoumarol, plasma concentration is measured, after liquid-liquid extraction, by liquid chromatograph, with ion trap mass spectrometer detector. [less ▲]

We investigated hemodynamics and plasma catecholamine concentrations in eight consecutive patients undergoing laparoscopic adrenalectomy for suspected pheochromocytoma. The same anesthesia protocol was used in all patients: a continuous infusion of sufentanil 0.5 microg x kg(-1) x h(-1) and isoflurane 0.4% (end-tidal) in 50% N2O/O2. Systolic arterial pressure was maintained between 120 and 160 mm Hg by adjusting an infusion of nicardipine, a calcium-channel blocker, while tachycardia (>100 bpm) was treated by 1-mg boluses of atenolol. Hemodynamics (thermodilution technique) and plasma catecholamine concentrations were measured before surgery, after the induction of anesthesia, after turning the patient to the lateral position, during pneumoperitoneum, during tumor manipulation, after adrenalectomy, and at the end of surgery. Two events resulted in significant catecholamine release: creation of the pneumoperitoneum and adrenal gland manipulation. As a consequence, a twofold increase in cardiac output was recorded. Adjustments of nicardipine infusion (2-6 microg x kg(-1) x min(-1)) minimized changes in mean arterial pressure. Beta-adrenergic blockade was necessary in six patients. In conclusion, laparoscopic adrenalectomy for pheochromocytoma results in marked catecholamine release during pneumoperitoneum and tumor manipulation. Titration of a nicardipine infusion allowed easy and quick control of the hemodynamic aberrancies related to these processes. IMPLICATIONS: Pneumoperitoneum during laparoscopy, now used for adrenalectomy, may complicate anesthetic management of patients with pheochromocytoma. In this study, laparoscopic adrenalectomy was associated with catecholamine release during the creation of pneumoperitoneum and tumor manipulation. Adjustments of a nicardipine infusion readily attenuated the subsequent hemodynamic aberrancies. [less ▲]

The objectives of the therapeutic drug monitoring are to assume the efficacy and inocuity of a medical treatment and the patient's observance. The administration of a drug to a patient is not always performed in the same conditions and therefore treatment has to be adapted. When necessary, this one is very often based on empiric or very approximative notions and, more seldom, on results of plasmatic concentrations of the drug. The CAPCIL program allows the possibility to objectivate the medical decision and adapt the posology on the basis of two kinetic parameters: the biological half-life and the distribution volume. Indeed, most of pharmacokinetics modifications (drug interactions, diseases, ...) are affecting the two parameters. With basic informations so as height and weight, posology, treatment objectives and peak/trough plasmatic concentrations of the drug, the program is proposing several posology adaptation schemes. The example of a once-a-day administration of amikacin is discussed. [less ▲]
