ABSTRACT
Lipoid pneumonia, although uncommon, should be considered when patients had a chronic pneumonia. We report a case of a 40-year-old female who presented with a chronic pneumonia. The CT-scan analysis, then the bronchoalveolar lavage, revealed a lipoid pneumonia. This lipoid pneumonia was caused by chronic inhalation of niaoulis vapors. This etiology has not been described in the literature. Alveolar condensation disappeared one month after bronchoalveolar lavage. This suggests that bronchoalveolar lavage may contribute to opacity regression besides exogenous lipid eviction.

Thymomas are uncommon neoplasms that account for 50% of all masses in the anterior mediastinum. Medial sternotomy is the typical approach for resection. We report a case of an ectopic thymoma within the right pleural cavity in a 76-year old Caucasian women. This patient was diagnosed on preoperative assessment with a large nodal lesion, measuring 12.5 × 9 × 11 cm. Extensive imaging and histology hinted the diagnosis of an ectopic thymoma type B1 according to the World Health Organisation (WHO) classification. Due to the rare location of this tumor, we decided to use a right lateral thoracotomy instead of the more commonly used medial sternotomy. Complete resection of the tumor was performed with relative ease and histopathology verified the diagnosis of a thymoma type B1. No continuity towards the superior anterior mediastinum was documented and the thymoma was considered 'ectopic'. To our knowledge ectopic thymomas are very rare, and few reports have been made about removing thymic tumors by means of a lateral thoracotomy.

The following recommendations, which aim at improving the clinical diagnosis ofTRALI and the laboratory investigations that can support it, were drawn up by a working group of the Superior Health Council. TRALI is a complication of blood transfusion that is both serious and underreported. Systematic reporting may help to develop preventive actions. Therefore, the Superior Health Council recommends that there should be a more stringent surveillance of patients who receive a blood component transfusion. The clinician should pay very close attention to any change in the patient's respiratory status (cf. dyspnoea and arterial desaturation), which should be notified systematically to the haemovigilance contact person in the hospital.

BACKGROUND: This randomized, double-blind study tested the hypothesis that, in comparison with midazolam, premedication with oral clonidine reduces the incidence of emergence agitation in preschool children anaesthetized with sevoflurane. METHODS: Sixty-eight ASA I-II children undergoing circumcision were randomized into three groups to receive different oral premedication given 30 min before anaesthesia: midazolam 0.5 mg kg-1, clonidine 2 microg kg-1, and clonidine 4 microg kg-1. Sevoflurane anaesthesia was administered via a facemask (O2/N2O: 40/60). Analgesia was with penile block (bupivacaine 0.5% 0.3 ml kg-1) and rectal paracetamol (30 mg kg-1). During the first postoperative hour, children were evaluated using a modified 'objective pain scale'. RESULTS: Only the 4 microg kg-1 dose of clonidine was associated with a significant reduction in emergence agitation. Fewer children in the clonidine 4 microg kg-1 group displayed agitation (25%) than in the midazolam group (60%) (P=0.025). Incidence of hypotension and bradycardia, time to first micturition and first drink did not differ among groups. CONCLUSIONS: In comparison with midazolam, clonidine 4 microg kg-1 reduced sevoflurane-induced emergence agitation without increasing postoperative side-effects.

Despite the continuous efforts to increase the safety of blood components, red blood cell transfusions remain associated with some risks and side effects. Therefore, numerous techniques have been developed to decrease blood use, but they also carry risks and bear costs. Most of them are frequently used in cardiac surgery, which still consumes a large part of the available blood supply. Among western countries the use of alternative techniques, but also transfusion practice, has been shown to vary markedly. 'Blood conservation' is a global concept engulfing all possible strategies aimed at reducing patients' exposure to allogeneic blood components. The development of the 'best strategy' consists of the selection of those techniques that are most appropriate to the local specific situation. It implies the establishment of a reliable system, collecting data both at the surgical team and at the medical level.

Six separation methods, developed on conventional silica high performance liquid chromatography (HPLC) columns were transferred to monolithic silica columns of 5 and 10 cm length. The transferred methods include the separation of an alkylbenzene mixture, the separations of drugs from their impurities (nimesulide, tetracycline, phenoxymethylpenicillin and erythromycin) and the separation of a green tea extract. The transfer of the first three methods was successful while for the latter three it was not. Increasing the flow rate up to 9 ml/min (where possible) inversely decreased the analysis time of the successfully transferred methods to 48 s (alkylbenzene mixture) 1.8 min (nimesulide mixture) and 3 min (tetracycline mixture) while still reasonable well separated peaks were obtained. The robustness and repeatability of the transferred and accelerated separations was found to be acceptable. Despite the use of flow rates up to 9 ml/min and frequent mobile phase changes with pH values varying from 3.5 to 7, the column performance was found to be rather constant and the column ageing to be minimal.

Between 1987 and 1995, 52 breast cancer patients had a surgical resection of lung secondaries. In 40 patients, the diagnosis of metastatic breast cancer could be confirmed following pathological examination. Five-year survival rates of these 40 patients was 54 +/- 8% and 5-year disease free survival was 30 +/- 8%. The median survival (70 months) of these patients was better than that of 57 patients with isolated lung metastases who had been treated conservatively (chemo- or/and hormonotherapy) during the same time interval. Twenty-six patients benefitted from a radical excision and had a longer disease free interval (42 versus 27 months, p = 0.03) than patients who had had a wedge resection. Overall survival was not significantly different (71 versus 41 months, p = 0.07). We feel that isolated lung nodules may best be treated by radical (segment or lobe) excision, in particular since preoperative differential diagnosis with primary lung cancer may be difficult. In the presence of multiple nodules, first line medical treatment by chemo- or hormonotherapy should be advocated, allowing to reduce the tumor load and to optimize survival in association with surgery.

BACKGROUND AND OBJECTIVES: 0.1% bupivacaine for obstetric epidural analgesia is given by infusion, using a loading dose of a higher concentration alone or in combination with opioid analgesics. A single dose of 0.1% without any additive for relief of first-stage labor pain has not yet been documented. METHODS: Fifty-eight primiparae in active labor and with less than 5 cm cervical dilatation received 20 mg epidural bupivacaine diluted in 4 mL [group 1: 0.5% (I)], 10 mL [group 2: 0.2% (II)], or 20 mL [group 3: 0.1% (III)]. Pain relief, dermatomal spread, and motor block were assessed. RESULTS: Visual analog pain scale (VAS) was significantly lower in group 2 (0.88 +/- 1.34) and group 3 (0.25 +/- 0.61) than in group 1 (4.37 +/- 2.57). Onset and time to maximum analgesia was significantly shorter in group 2 than in group 3. Mean duration of analgesia was 120 +/- 21 minutes in group 3, 100 +/- 26 in group 2, and 43 +/- 21 in group 1. The mean numbers and upper limits of dermatomes blocked did not differ between groups 2 and 3, but were higher than in group 1. Motor blocks in groups 2 and 3 were more extensive than in group 1 with no difference between groups 2 and 3. Ten mL 0.2% or 20 mL 0.1% epidural bupivacaine results in a similar degree of pain relief, superior to that following 4 mL 0.5%, while duration was longest after 20 mL 0.1%. CONCLUSIONS: Analgesia lasts significantly longer following 20 mL 0.1% bupivacaine than following 10 mL 0.2% bupivacaine when given for first-stage labor pain. Four milliliters 0.5% bupivacaine results in inadequate pain relief.

PURPOSE: Analysis of the preliminary results of a phase I study investigating the feasibility of concomitant chemotherapy with daily doses of carboplatin (20 to 25 mg/m2/d over 45 or 10 min) and accelerated chest irradiation (60 to 64 Gy over 4 weeks, 2 Gy per fraction, using the concomitant boost technique). MATERIALS AND METHODS: This combination was given alone or following three cycles of induction chemotherapy (cisplatin, 25 mg/m2 per day from d1 to d5; 5-fluorouracil, 600 mg/m2 per day from d1 to d5 and vinorelbine, 25 mg/m2 per day at d1 and d5 with a 4-week interval) in 15 patients with locally advanced unresectable non-small cell lung cancer. All patients received the planned sequence. RESULTS: The dose-limiting toxicity was esophagitis (5 out of 15 grade 4). No toxic deaths were observed. The tumor response rate was high: six out of 15 complete responses and 14 out of 15 tumor regressions greater than 50%. The median survival was not reached after a mean follow-up of 14 months (range, 6-28 months). CONCLUSION: We are now planning a multicenter phase II study using the following combination: 20 mg/m2 of daily carboplatin over 10 min and a 60-Gy irradiation dose over 4 weeks.

Thirty-three patients, with histologically proven advanced nonsmall cell lung cancer (NSCLC) were treated at Institut Curie with a three-drug combination chemotherapy. The regimen consisted of cisplatin 25 mg/m2 per day continuous infusion (CI) and 5-fluorouracil (5-FU) CI 600 mg/m2 on 5 consecutive days with 30 minutes infusion navelbine 25 mg/m2 on days 1 and 5 only. Cycles were repeated every 28 days. Response was evaluated after three cycles. One patient died of an ischemic cerebrovascular stroke after the third cycle. Thirty-two pts were evaluable. Partial response was achieved in 11/20 patients with stage III disease (55%) and in 7/12 patients with stage IV disease (58%). WHO grade 4 toxicities were leucopenia 31%, thrombocytopenia 4%, and mucositis 4%. The tolerance was acceptable. Median survival was 19 months for stage III and 9.5 months for stage IV. We conclude that the combination of 5-FU, navelbine, and cisplatin is an effective chemotherapy regimen for patients with advanced stage NSCLC.

PURPOSE: To assess the diagnostic value of parametric magnetic resonance images that display the first pass (FP) of gadopentetate dimeglumine. MATERIALS AND METHODS: Dynamic, contrast material-enhanced, fast low-angle shot MR imaging was performed of 100 musculoskeletal lesions in 36 female and 64 male patients (aged 9-81 years [mean, 34 years]). The highest slope value of the time-intensity curve was calculated pixel by pixel and displayed on the FP image, with a gray-scale value equal to the slope value. Tissue vascularization and perfusion were evaluated at pathologic and angiographic examinations in 33 lesions. RESULTS: A significant difference (P < .001) was found between the FP slope values of benign (mean, 36.2% per second) and malignant (mean, 67.4% per second) lesions. FP images depicted tissue vascularization and perfusion rather than benignity or malignancy, because there is an overlap in the slope values of highly vascular benign lesions and malignant lesions. CONCLUSION: FP images provide diagnostically useful information by depicting tissue vascularization and perfusion.

The purpose of this study was to evaluate the diagnostic value of parametric images which display the first-pass of Gd-DTPA after intravenous bolus injection. Single slice dynamic contrast-enhanced MRI (Turbo-FLASH) with a temporal resolution of 2.41 s was performed in 40 benign and malignant musculoskeletal lesions. Parametric 'first-pass' images were obtained by using a new postprocessing technique, derived from a home written computer program, which calculated the steepest slope of the time-intensity curve pixel by pixel. First-pass images provided qualitative and quantitative information, which was useful for diagnosis and therapy. Demonstration of the areas with the highest vascularization was very helpful in planning the best biopsy site in 6 patients and to delineate tumor from peritumoral muscle edema in 4 patients. In 10 patients the first-pass images provided additional information, which was not visible on the conventional spin-echo images. The most promising application was the ability to evaluate the response to preoperative chemotherapy in a patient with Ewing's sarcoma. Although a highly statistically significant difference (p < 0.001) was found between the first-pass slope values of benign and malignant lesions, the sensitivity (77%) and specificity (71%) of this method were too low to permit a definite differentiation of highly vascular benign from malignant lesions. Pathologic examination of 17 lesions, performed in the plane of the first-pass image, showed a good correlation between the first-pass slope values and the vascularization of the tissues.(ABSTRACT TRUNCATED AT 250 WORDS)

The DNA content of the cell nuclei of Ewing's sarcoma was analysed by means of cytophotometry in situ with image analysis in Feulgen-stained sections in 37 patients, and by retrospective flow cytometry according to the method of Hedley in 26 patients. Different histogram patterns were obtained: normal unimodal or bimodal DNA distributions and abnormal DNA distributions with one or two stem lines, or an abnormal DNA distribution with no stem lines. Both methods enabled us to make a distinction between two groups of Ewing's sarcomas with a different prognosis. All patients with aneuploid tumours died within 5 years after the initial diagnosis. Eleven of 19 (58%) patients with a normal DNA distribution in their tumour, as determined by cytophotometry, are still alive and in good health with a mean survival period of 7.5 years, ranging from 2 to 19 years. Of the group of patients in which flow cytometry revealed a normal DNA pattern, eight of 15 (53%) are still alive and in good health, with a mean survival period of 8 years. These results indicate that both techniques are reliable methods for obtaining prognostic information in Ewing's sarcomas. However, cytophotometry in situ yielded a better discrimination for the overall survival (P < 0.01) than did flow cytometry (P < 0.05). In 19% of the cases there was a discrepancy between the DNA histograms obtained with the two techniques. In five of 26 cases the DNA distributions were classified as normal by one method and aneuploid by the other. Tumour cell representation or selective loss of cells during enzymatic treatment may be responsible for this discrepancy.

Since 1963, 53 cases of Ewing's sarcoma have been diagnosed at the N. Goormaghtigh Institute of Pathological Anatomy. All tumours were classified according to their growth pattern as described by Kissane: diffuse, lobular or organoid, the latter with pseudorosettes, or belonging to the fillagree type. In 45 cases, an immunohistochemical examination was carried out on routinely processed material in order to determine the immunophenotype of the tumours and to get more information on the histogenesis of the tumours. Antibodies against cytokeratin, desmin, vimentin, neurofilaments, neuron-specific enolase, Leu7, synaptophysin, chromogranin, the muscle-specific actin, the Von Willebrand factor and the common leucocyte antigen were used in a biotin-streptavidin procedure. The presence of neural markers such as neuron-specific enolase, synaptophysin and Leu7 was proved in the majority of the cases. The expression of the three markers was absent in only two cases. Neurofilaments were demonstrated to be present in 5 of the 6 cases for which fresh material was available. The results of this study point towards a possible neuroectodermal origin of Ewing's sarcoma. This is in agreement with the results of cell culture experiments and of cytogenetic studies.

INTRODUCTION: the association of acute febrile neutrophilic dermatosis (Sweet's syndrome) with malignant haemopathies is well known and characterized by an usual lack of hyperleukocytosis: indeed, moderate neutropenia is often reported. However, cases of Sweet's syndrome in the agranulocytosis stage are exceptional (7 in the literature). CASE-REPORT: We report the case of a woman with acute myeloblastic leukaemia who had presented with Sweet's syndrome in the phase of therapeutic aplasia during induction of treatment, in the absence of white blood cells transfusion or treatment with haematopoietic growth factor (GM CSF, GCSF). COMMENTS: the physiopathology of Sweet's syndrome is unknown. Various mechanisms have been suggested, including immune reaction type III, increased interleukin-1 synthesis, increased chemotaxis of neutrophils, action of haematopoietic growth factors, iatrogenic effect of some drugs (e.g. cotrimoxazole, furosemide or minocycline). Yet none of these mechanisms involving circulating polymorphonuclears or their bone marrow precursors can explain the occurrence of Sweet's syndrome in the phase of agranulocytosis. CONCLUSION: the diagnosis of Sweet's syndrome must be considered in patients with agranulocytosis in order to avoid ineffective antibiotics and to initiate a corticosteroid therapy that will accelerate the cure of this benign dermatosis.

Tumors of nerves are classified into benign (schwannoma and neurofibroma) and malignant nerve sheath tumors. Schwannomas almost always occur as solitary lesions, whereas neurofibromas may occur alone or in a greater number, especially in patients with the peripheral form of von Recklinghausen's disease. Benign nerve sheath tumors often present as asymptomatic, slowly growing soft tissue masses. Although malignant nerve sheath tumors are relatively rare, a sudden increase in the size of a lesion, in particular in a patient with neurofibromatosis, should raise the suspicion of malignant change. On computed tomography (CT) and magnetic resonance imaging (MR) a benign nerve sheath tumor usually appears as a well-defined, oval, spherical or fusiform mass with smooth borders and distinct outlines, located in the subcutaneous tissue or centered at the expected anatomic location of a nerve, with displacement of adjacent soft tissues. Generally nerve sheath tumors have a low density on unenhanced CT scans. On MR they are isointense to muscle on T1-weighted images, whereas on T2-weighted images the signal intensity is high. Both on CT and MR the degree of contrast enhancement is moderate to marked and may be homogeneous or inhomogeneous. MR has become the method of choice for evaluating the anatomic location, contour, and relation of a nerve sheath tumor to adjacent neural, vascular, and muscular structures. The imaging criteria for malignant nerve sheath tumors are not specific enough to distinguish them from other malignant soft tissue tumors, so that neither CT nor MR can establish a definite diagnosis.

As reported before elastofibroma dorsi is a rare benign tumor of elastic connective tissue with typical clinical and suggestive radiological features. We evaluated the CT and MR characteristics of this periscapular lesion in a new case, before and after contrast enhancement, and tried to determine in how far the nature and extent of the tumor can be predicted.

Fluorescence in situ hybridization (FISH) using chromosome-specific plasmid libraries and chromosome region-specific DNA markers allowed the characterization of a t(10;22;11) (p11.2;q12;q24) in a Ewing's sarcoma (ES). This study illustrates the usefulness of molecular cytogenetic analysis of ES, especially for determining the localization of the translocated 11q24-25 segment in complex or variant translocations.
