Differential viral protein expression in Kaposi's sarcoma-associated herpesvirus-infected diseases: Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease.

Kaposi's sarcoma (KS)-associated herpesvirus (KSHV) is linked to KS, primary effusion lymphomas (PEL), and a subset of multicentric Castleman's disease (MCD). Transcript mapping studies using PEL cell lines have allowed preliminary classification of viral gene expression into constitutive (class I) and inducible (class II/III) categories. To determine whether viral gene expression differs in vivo, we examined tissue sections of KSHV-infected disorders, using specific antibodies against proteins that are representative of the different expression classes of KSHV genes. ORF73/LANA appears to be a surrogate marker for KSHV infection because it is constitutively expressed in vitro and in vivo in all KSHV-infected cells. Expression of vIRF1, vIL6, and PF-8 proteins in the infected B cells of MCD lymph nodes reproduces the expression pattern observed in TPA-stimulated KSHV-infected B-cell lines. In contrast, the protein expression of the inducible viral genes that we tested in KS and PEL biopsies is restricted to PF-8 and vIL6, respectively. The tightly restricted expression of KSHV proteins in vivo differs from the dysregulated expression of inducible KSHV genes in vitro and suggests that viral gene expression in KSHV-infected cell lines does not accurately reflect what occurs in diseased tissues. These differences may be related to either cell-specific or immune restriction of viral replication.

[Laparoscopic treatment of perforated duodenal ulcers. Results of a retrospective multicentric study. French Society of Laparoscopic Surgery].

STUDY AIM: The aim of this multicentric retrospective study was to report procedures, mortality and morbidity rate in a series of patients operated on for perforated duodenal ulcer with a laparoscopic approach. PATIENTS AND METHODS: Four-hundred and nineteen patients from 18 centers were included. The duration of the study was ten years (1990 to 1999). There were 299 men and 120 women aged from 19 to 98 years (mean: 48 years). The ASA scores were as follows: I (48.7%), II (31.3%), III (17.5%), IV (2.5%). The mean duration between the onset of perforation and the time of operation was 13.4 hours (range: 1-70). The surgical procedures were suture (76.7%), epiploplasty (9.9%), only irrigation of the abdominal cavity (2.7%). RESULTS: Conversion into laparotomy was performed in 10.6% of the patients. Mean operative time was 85 minutes. The morbidity and mortality rates were 13.4 and 1.4% respectively. Seventeen patients were reoperated because of fistula (n = 5), intra-abdominal abscess (n = 5), small bowel obstruction (n = 4), bleeding ulcer (n = 1), iatrogenic perforation of the gallbladder (n = 1) and small bowel (n = 1). Mean hospital stay was 8.5 days. All patients were discharged with a medical treatment of the peptic ulcer disease and in most of the cases, with antibiotics for Helicobacter pylori eradication. Six patients out of 96 with a medical history of chronic peptic ulcer underwent a vagotomy. CONCLUSION: Laparoscopic repair of perforated duodenal ulcer is a safe option providing low rates of morbidity, reoperation and mortality, and can be considered the treatment of choice.

Multicentric reference values for some quantities measured with the Elecsys 2010 analyser.

Several clinical laboratories in different regions of Spain have shared the search for reference individuals and the production of reference values for quantities concerning thyrotropin, non-protein bound thyroxine, triiodothyronine, cobalamines and folates, using an Elecsys 2010 analyser. All the logistic work has been done in co-operation with the supplier of the analyser (Roche Diagnostics España, S.L., Barcelona). The reference limits produced in the virtual laboratory are in fact derived from the blend of reference values obtained by each laboratory. The multicentric reference limits were estimated according to the recommendations of the International Federation of Clinical Chemistry. The work done represents a model of co-operation between the in vitro diagnostic industry and clinical laboratories for the production of reference values.

Multicentre evaluation of a new point-of-care test for the quantitative determination of D-dimer.

Imprecision studies, interference testing and multicentre method comparisons using patient samples were carried out with of a new point-of-care test for D-dimer (CARDIAC D-Dimer). The CV of the within-series and the day-to-day imprecision with blood samples and control materials were between 7% and 13%. Compared with Tina-quant D-Dimer, CARDIAC D-Dimer showed a good correlation and accuracy (n=353; r=0.91; y=1.06x-0.03), compared with STA LIATEST D-Dimer some poorer accuracy (n=304; r=0.91; y=1.12x-0.03). No interference was detected for different hematocrit values (16% to 51%) and in investigations with hemoglobin (up to 0.13 mmol/l), biotin (up to 30 microg/l), bilirubin (up to 340 micromol/l), intralipid (up to 31.1 mmol/l) and rheumatic factor (up to 79 IU/ml). Overdosing or underdosing by 10 microl did not affect the test result. The diagnostic sensitivity of CARDIAC D-Dimer for the detection of acute venous thromboembolic diseases was 100% in our study. With CARDIAC D-Dimer reliable quantitative D-dimer results can be easily obtained. Because of the good analytical and clinical agreement with Tina-quant D-Dimer, it should be suitable for ruling out venous thromboembolic diseases.

Usefulness of a simple photometric determination of chymotrypsin activity in stools--results of a multicentre study.

The usefulness of a new photometric test for the determination of chymotrypsin activity in stools was evaluated in a multicentre study. By release of the enzyme from stool particles with a cationic detergent solution after, in most cases, 3 min of homogenization, a photometric measurement of the enzyme activity is possible both in the clear supernatant after centrifugation and in the diluted stool homogenate. The precision of the activity measurement in stool samples with pathologically lowered and normal chymotrypsin activity is good both for in-series (CV = 2.6%, scatter 0.6-5.7%) and for day-to-day determinations (CV = 7.2%, scatter 3.9-13.9%). The results obtained by the photometric determination also exhibit a close correlation with the values measured by pH-stat titrimetry (r = 0.901). The sample-preparation system with a sample-metering chamber is easy to use and gives good agreement with determinations in which the sample metering was done by weighing out the stool (r = 0.961). The photometric test for detection of exocrine pancreatic insufficiency is easy to perform, inexpensive and does not place any undue stress on the patient.

Blunt gastric injury. A multicentre experience.

A multicentre retrospective analysis of blunt gastric injuries from four trauma centres in Brazil was performed. From January 1982 to May 1996, 33 patients were found to have blunt gastric injury: 26 were male and the mean age was 26.2 years. The most frequent mechanism of injury was automobile versus pedestrian (17) followed by motor vehicle accidents (seven). Abdominal pain was the most common finding (29) and peritoneal signs were present in 14. There were 21 grade I, seven grade II, four grade III and one grade IV blunt gastric injuries. Simple suture was the treatment of choice in 24 patients, eight required no treatment, and only one patient underwent gastric resection. The liver and spleen were the most commonly associated injured organs. Two patients had isolated gastric injury. There were two gastric fistulae and both patients died. Overall morbidity and mortality was 12 (36%) and nine (27%), respectively. The ISS was higher in the non-survivor group (P=0.03) and the gastric organ injury score did not reach statistical significance when comparing survivors and non-survivors. We conclude that blunt gastric injury is uncommon and is associated with other injuries of greater magnitude, which generally influence mortality.

Treatment of diaphyseal fractures of the forearm using the Point Contact Fixator (PC-Fix): results of 387 fractures of a prospective multicentric study (PC-Fix II).

Fractures of the forearm are considered to be a very good indication for plating. Conventional plating is still technically demanding. Extensive animal studies show that there is potential for improvement. The method consists of using an internal fixator that minimizes implant contact to the bone to reduce biological damage. Furthermore, foregoing the need for precise reduction and interfragmental compression makes it easier to use and, therefore, it should be safer. The goal of the study was to observe handling qualities, healing, and complications. For this purpose the study was designed to yield a very high follow-up in clinics with adequate experience and with a number of different surgeons performing the internal fixation. The study was designed as a prospective multicentre investigation in 16 trauma centres worldwide. To test the new approach to internal fixation, diaphyseal fractures of the forearm were stabilized surgically with the PC-Fix (Point-Contact Fixator) system, namely, 387 fractured bones involving 277 forearms in 272 patients. Internal fixation was performed using 387 PC-Fixators. 21% of the fractures were open and 25% occurred in polytraumatized patients. The rate of follow-up was 97%. 355 fractured bones healed uneventfully within four months. Overall, there were 32 complications before bone union occurred; 27 of these bones required re-operation (27 of 387, 7%). All of them subsequently healed without further complications. There were 15 delayed or non-unions and seven implant loosenings, two of which were associated with infection. Two superficial (0.6%) and two deep infections (0.6%) occurred in 306 closed fractures. Deep infection developed in one of 81 osteosyntheses of open fractures (1.2%). Other complications included one synostosis, fractures with the implant in situ with adequate trauma involving three bones, and two secondary correction procedures for postoperative malalignment. There were seven refractures occurring at a mean of three weeks after the removal of 150 PC-Fixators (4.7%). This study demonstrated that the technique of using an internal fixator is a simple one for the fixation of forearm fractures, resulting in shorter duration of surgery with a low rate of complications compared with the data reported in the literature on conventional techniques for forearm fracture stabilization.

International Standards for hepatocyte growth factor/scatter factor: initial assessment of candidate materials and their evaluation by multicentre collaborative study.

Hepatocyte growth factor/scatter factor (HGF/SF) is a potent paracrine growth factor with motogenic, mitogenic and morphogenic activities, and a potential therapeutic role in hepatic and renal disease, as well as diagnostic and prognostic applications. It is synthesised as an inactive, single-chain precursor that is cleaved by serine proteases to give a biologically active, heterodimeric form. To develop World Health Organization (WHO) International Standards (IS) for HGF/SF, candidate preparations of the two forms were assessed in a multicentre study in which they were compared with local standards by bioassay and immunoassay. Among laboratories, there was a wide variation in the estimates of potencies of the candidate standards in terms of in-house reference preparations, but between-assay and within-assay variabilities were low within laboratories. In some assay systems, the precursor and heterodimer showed different responses. Since both molecular forms are widely used in current assay systems, this suggested that a reference preparation was required for each form of the HGF/SF molecule. Accordingly, the Expert Committee on Biological Standardization of WHO established the heterodimeric material (96/564) as the first IS for HGF/SF, human, recombinant, with an assigned unitage of 4000 IU/ampoule and, for the purpose of immunoassay calibration, a nominal HGF/SF content of 4 microg/ampoule. The precursor preparation (96/556) was established as the first IS for HGF/SF (precursor) with an assigned unitage of 2000 IU/ampoule and, for the purpose of immunoassay calibration, a nominal HGF/SF (precursor) content of 4 microg/ampoule. The preparations can be obtained upon written request to the National Institute for Biological Standards and Control (NIBSC, PO Box 1193), by e-mail (standards@nibsc.ac.uk) or ordered at http://www.nibsc.ac.uk.

Involvement of the spleen by renal angiomyolipoma: metastasis or multicentricity?

Angiomyolipoma has been regarded as a benign renal neoplasm composed of adult fat cells, atypical blood vessels and smooth muscle. We report a case in which a renal angiomyolipoma showed clear evidence of involvement of the spleen and regional lymph nodes. The consensus in the literature suggests that this phenomenon is a manifestation of the multicentric nature of angiomyolipoma, rather than metastasis.

Multicentric renal oncocytoma.

Renal cell oncocytomas are benign tumors of tubular epithelial origin. They usually occur as single nodules and may be confused clinically with renal cell carcinoma. We report an unusual case of multiple, discrete renal cell oncocytomas. The characteristic gross and light microscopic, and ultrastructural features are described. The potential of multicentricity is confirmed and its implications for therapy are discussed.

[Complications of surgical treatment of spinal deformities: a prospective multicentric study of 3311 patients].

PURPOSE OF THE STUDY: The incidence of complications secondary to surgical treatment of spinal deformations remains imprecise. The purpose of this prospective multicentric observational study was to assess the incidence of intra- and postoperative complications secondary to this type of surgery to detail the observed complications and to identify favoring factors. MATERIAL AND METHODS: For this study, we included 3311 patients who underwent surgery during a 12-month period for spinal deformation, defined as idiopathic or secondary scoliosis or kyphosis, irrespective of the localization, severity, or type of surgery performed. Four main categories of complications were studied: general, infectious, neurological, and mechanical. Pre- and intraoperative variables recorded were: epidemiological and morphological data, history of surgery for the same spinal deformation, comorbid conditions, type of deformation treated (nature, anatomic localization, severity, reducibility), type of surgery performed (approach, duration of the operation), operative blood loss, extent and localization of the fusion, associated neurological release, vertebral osteotomy or not, type of graft used. Two types of analysis were performed. The first was a descriptive analysis to detail the overall incidence of complications and the incidence of each of the four main categories. The second was a multivariate analysis designed to determine factors significantly associated with complication occurrence. RESULTS: Mean age of the cohort was 27 +/- 18 years; 6.8% of the patients had had a prior operation for the spinal deformation. The deformation was scoliosis in 90% (mean angle 56 +/- 20 degrees) and kyphosis in 10% (mean angle 47 +/- 23 degrees). An isolated posterior approach was used for 72.5% of patients, an isolated anterior approach for 6.4%, and a combined anteroposterior approach for 21.1%. Seven hundred four patients (21.3%) had one or more complications (850 complications) during or shortly after their operation. The incidences of general, infectious, mechanical and neurological complications were: 5.7%, 4.7%, 11.5%, and 1.8% respectively. Globally, considering all types of complications, the following factors were found to be significantly associated with complication occurrence: patient age, ASA score, extent of the fusion, presence of vertebral osteotomy, inclusion of the sacrum in the arthrodesis, and initial angle of the treated deformation. For patients with scoliosis, the following factors were significantly associated with a secondary central neurological disorder: initial angle of the deformation, use of vertebral osteotomy, type of curvature with greater risk for thoracic curvatures and double thoracic and lumbar curvatures. CONCLUSION: This work enabled us to determine the overall rate of complications after surgical treatment of spinal deformations. Certain risk factors related with complication occurrence were identified, but the heterogeneous nature of the population and the methodology used to identify these factors only allowed detection of trends. A future study by etiological group or focusing on specific complications should allow a more precise analysis of these risk factors. This overall rate of complications should be used to better inform patients and their family about the risks of this type of surgery.

[Arthroscopic repair of full-thickness cuff tears: a multicentric retrospective study of 576 cases with anatomical assessment].

PURPOSE OF THE STUDY: Totally arthroscopic repair of rotator cuff tears is now common practice. The techniques used were evaluated by a retrospective multicentric analysis conducted by the French Society of Arthroscopy. MATERIAL AND METHODS: The series was limited to arthroscopic repair of full thickness tears of the supraspinatus or infraspinatus evaluated using the Constant score and arthro-MRI or arthroscan performed with at least one year follow-up. Data were processed with SPSS 10. The series included 576 patients who underwent surgery between January 2001 and June 2003. Mean patient age was 57.7 years; 52% were men and 60% were manual laborers. The mean preoperative Constant score was 46.4 +/- 13.4/100. The tear was limited to the supraspinatus in 69% of shoulders, with extension to the upper third of the infraspinatus in 23.5% and the entire infraspinatus in 7.5%. The supraspinatus tear was distal in 41.7% of shoulders, intermediary in 44% and retracted in 14.3%. Fatty degeneration of the supraspinatus was noted grade 0 in 60%, 1 in 27%, 2 in 11% and 3 in 2%. Arthroscopic repair was performed in all cases, with locoregional anesthesia in 60.9%. Bioresorbable implants were used in 33% and metallic implants in 62.1%. Acromioplasty was performed in 92.7% and capsulotomy in 14.9%. RESULTS: On average, the subjective outcome was scored 8.89/10. The Constant score improved from 46.3 +/- 13.4 to 82.7 +/- 10.3 with 62% having a strictly pain free shoulder. Muscle force improved from 5.8 +/- 3.7 to 13.6 +/- 5.4. Outcome was excellent in 94% of shoulders at 18.5 months mean follow-up. The complication rate in this series was 6.2% with 3.1% prolonged stiffness, 2.7% reflex dystrophy, 0.2% infection, and 0.2% anchor migration. The cuff was considered normal in 55.7% of shoulders with an intratendon addition image in 19%, i.e. 74.7% of non-ruptured cuffs. Minimal loss of integrity was noted in 9.5% and was marked in 15.7%, i.e. 25.2% iterative tears.ANATOMOCLINICAL CORRELATIONS: The Constant score was strongly correlated with rotator cuff integrity (p<0001). This correlation was also found for force (p<0001), motion (0.01) and activity (0.04), but not for pain. The clinical outcome was correlated with extension, retraction, intrasubstance tear, and fatty degeneration of the lesion preoperatively. Anatomic results were statistically less favorable for tears which were older, extensive, retracted or associated with fatty degeneration. Age was correlated with extent of the initial tear and also with less favorable anatomic and clinical outcome. Occupational accidents were correlated with less favorable clinical outcome. CONCLUSION: Functional improvement after healing is a strong argument for repair. Arthroscopy has the advantage of combining a low complication rate with good clinical and anatomic results. Age is correlated with functional outcome and healing, but is not a contraindication.

Genotyping of Plasmodium falciparum infections by PCR: a comparative multicentre study.

Genetic diversity of malaria parasites represents a major issue in understanding several aspects of malaria infection and disease. Genotyping of Plasmodium falciparum infections with polymerase chain reaction (PCR)-based methods has therefore been introduced in epidemiological studies. Polymorphic regions of the msp1, msp2 and glurp genes are the most frequently used markers for genotyping, but methods may differ. A multicentre study was therefore conducted to evaluate the comparability of results from different laboratories when the same samples were analysed. Analyses of laboratory-cloned lines revealed high specificity but varying sensitivity. Detection of low-density clones was hampered in multiclonal infections. Analyses of isolates from Tanzania and Papua New Guinea revealed similar positivity rates with the same allelic types identified. The number of alleles detected per isolate, however, varied systematically between the laboratories especially at high parasite densities. When the analyses were repeated within the laboratories, high agreement was found in getting positive or negative results but with a random variation in the number of alleles detected. The msp2 locus appeared to be the most informative single marker for analyses of multiplicity of infection. Genotyping by PCR is a powerful tool for studies on genetic diversity of P. falciparum but this study has revealed limitations in comparing results on multiplicity of infection derived from different laboratories and emphasizes the need for highly standardized laboratory protocols.

Respiratory obstruction caused by a multicentric granular cell tumor of the laryngotracheobronchial tree.

An unusual case of acute respiratory obstruction caused by multicentric granular cell tumors of the laryngotracheobronchial tree is presented. The patient also had granular cell tumors in the tongue, vulva, and chest wall. Multiplicity of the lesions in the left lung and recurrent episodes of intercurrent pulmonary infections necessitated left pneumonectomy. The extreme rarity of such a clinical circumstance is illustrated by a review of the literature. Salient clinical and pathological features of the tumor are briefly discussed.

Multicentric giant lymph node hyperplasia: an immunohistochemical study.

Biopsy specimens from five cases of multicentric giant lymph node hyperplasia were studied by standard histochemical techniques and by immunoperoxidase staining and double immunoenzyme labeling to determine the distribution of intracytoplasmic immunoglobulins and kappa and lambda light chains. Microscopically, the affected lymph nodes showed a nodular pattern characterized by multiple lymphoid follicles permeated by numerous small vessels. A striking proliferation of post-capillary venules with many plasma cells and immunoblasts was observed in the interfollicular areas. Immunoperoxidase staining revealed that the cells were positive for IgG, IgA, and IgM with both kappa and lambda chains in the normal ratio. The IgM-positive cells had a perifollicular distribution, whereas the IgG- and IgA-positive cells were located mainly in interfollicular areas. The presence and distribution of different classes of intracytoplasmic immunoglobulins seemed to reflect a normal, albeit tumultuous, immunologic response. Therefore, the disease can be considered a lymphoproliferative disorder due to an inappropriate immunologic reaction.

Multicentric renal angiomyolipoma associated with pulmonary lymphangioleiomyomatosis: case report, with histologic, immunohistochemical, and DNA content analyses.

A 26-year-old pregnant woman presented with pulmonary lymphangioleiomyomatosis (LAM) and multicentric angiomyolipoma (AML) involving the left kidney and perirenal lymph nodes. In both tumors, smooth muscle cells were the predominant component. Immunohistochemically, these cells stained for vimentin, smooth muscle actin, desmin, and HMB-45. Estrogen receptors were weakly positive in LAM and negative in AML. Progesterone receptors were negative for both lesions. DNA content analysis studies showed the renal AML to be diploid with a minor aneuploid component, the lymph node AML aneuploid, and the LAM diploid. The diagnostic and prognostic significance of hormonal studies and DNA content analysis are discussed.

Comparison of radiotherapy alone with radiotherapy plus hyperthermia in locally advanced pelvic tumours: a prospective, randomised, multicentre trial. Dutch Deep Hyperthermia Group.

BACKGROUND: Local-control rates after radiotherapy for locally advanced tumours of the bladder, cervix, and rectum are disappointing. We investigated the effect of adding hyperthermia to standard radiotherapy. METHODS: The study was a prospective, randomised, multicentre trial. 358 patients were enrolled from 1990 to 1996, in cancer centres in the Netherlands, who had bladder cancer stages T2, T3, or T4, NO, MO, cervical cancer stages IIB, IIIB, or IV, or rectal cancer stage M0-1 were assessed. Patients were randomly assigned radiotherapy (median total dose 65 Gy) alone (n=176) or radiotherapy plus hyperthermia (n=182). Our primary endpoints were complete response and duration of local control. We did the analysis by intention to treat. FINDINGS: Complete-response rates were 39% after radiotherapy and 55% after radiotherapy plus hyperthermia (p<0.001). The duration of local control was significantly longer with radiotherapy plus hyperthermia than with radiotherapy alone (p=0.04). Treatment effect did not differ significantly by tumour site, but the addition of hyperthermia seemed to be most important for cervical cancer, for which the complete-response rate with radiotherapy plus hyperthermia was 83% compared with 57% after radiotherapy alone (p=0.003). 3-year overall survival was 27% in the radiotherapy group and 51% in the radiotherapy plus hyperthermia group. For bladder cancer, an initial difference in local control disappeared during follow-up. INTERPRETATION: Hyperthermia in addition to standard radiotherapy may be especially useful in locally advanced cervical tumours. Studies of larger numbers of patients are needed for other pelvic tumour sites before practical recommendations can be made.

Surgery and postoperative radiotherapy versus surgery alone for patients with stage-1 endometrial carcinoma: multicentre randomised trial. PORTEC Study Group. Post Operative Radiation Therapy in Endometrial Carcinoma.

BACKGROUND: Postoperative radiotherapy for International Federation of Gynaecology and Obstetrics (FIGO) stage-1 endometrial carcinoma is a subject of controversy due to the low relapse rate and the lack of data from randomised trials. We did a multicentre prospective randomised trial to find whether postoperative pelvic radiotherapy improves locoregional control and survival for patients with stage-1 endometrial carcinoma. METHODS: Patients with stage-1 endometrial carcinoma (grade 1 with deep [> or =50%] myometrial invasion, grade 2 with any invasion, or grade 3 with superficial [<50%] invasion) were enrolled. After total abdominal hysterectomy and bilateral salpingo-oophorectomy, without lymphadenectomy, 715 patients from 19 radiation oncology centres were randomised to pelvic radiotherapy (46 Gy) or no further treatment. The primary study endpoints were locoregional recurrence and death, with treatment-related morbidity and survival after relapse as secondary endpoints. FINDINGS: Analysis was done according to the intention-to-treat principle. Of the 715 patients, 714 could be evaluated. The median duration of follow-up was 52 months. 5-year actuarial locoregional recurrence rates were 4% in the radiotherapy group and 14% in the control group (p<0.001). Actuarial 5-year overall survival rates were similar in the two groups: 81% (radiotherapy) and 85% (controls), p=0.31. Endometrial-cancer-related death rates were 9% in the radiotherapy group and 6% in the control group (p=0.37). Treatment-related complications occurred in 25% of radiotherapy patients, and in 6% of the controls (p<0.0001). Two-thirds of the complications were grade 1. Grade 3-4 complications were seen in eight patients, of which seven were in the radiotherapy group (2%). 2-year survival after vaginal recurrence was 79%, in contrast to 21% after pelvic recurrence or distant metastases. Survival after relapse was significantly (p=0.02) better for patients in the control group. Multivariate analysis showed that for locoregional recurrence, radiotherapy and age below 60 years were significant favourable prognostic factors. INTERPRETATION: Postoperative radiotherapy in stage-1 endometrial carcinoma reduces locoregional recurrence but has no impact on overall survival. Radiotherapy increases treatment-related morbidity. Postoperative radiotherapy is not indicated in patients with stage-1 endometrial carcinoma below 60 years and patients with grade-2 tumours with superficial invasion.
