State of transition to Ministry of Health governance of prison healthcare in the Council of Europe region. Public Health 2024; 229:151-159. [PMID: 38442597 DOI: 10.1016/j.puhe.2024.01.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 12/16/2023] [Accepted: 01/22/2024] [Indexed: 03/07/2024]
Abstract
OBJECTIVES This study aimed to examine timebound prison healthcare governance amendments and current structures in Europe two decades after the World Health Organization (WHO) Declaration on Prison Health as part of Public Health adopted in Moscow on 24 October 2003 (Moscow Declaration), which recommended prison health care be closely linked with public health systems to ensure quality prison health care, connected health surveillance, and continuity of care. STUDY DESIGN We present here a regional evolutionary mapping of the Council of Europe Member State transfer of prison healthcare governance to the auspices of the Ministry of Health. METHODS The European Committee for the Prevention of Torture database and WHO Regional Office for Europe Health In Prison European Database were scrutinised for Council of Europe (CoE) Member State status regarding the Ministry responsible for prison healthcare governance and if this had changed since the adoption of the Moscow Declaration in 2003. RESULTS As of October 2023, completed transfer of governance to the Ministry of Health nationally is documented in 13 CoE Member States and in one CoE Member State candidate (Kosovo). Partial transfer is documented in Spain (Catalonia and Basque Autonomous Community) and Switzerland (cantons of Geneva, Valais, Vaud, Neuchatel, and Basel-Stadt). Three CoE Member States operate joint governance of prison health care between Ministries (Malta, Portugal, Türkiye). Transfer is a lengthy process (up to 10 years). CONCLUSIONS Successful transition requires political commitment, cooperation, needs assessment, resourcing, and evaluation. Monitoring of cost and prison healthcare standards, due process for complaints, and cooperation with independent/Committee against Torture inspections is critical.

Abstract
INTRODUCTION The aim of the study was to evaluate the use of intramammary antibiotics before, during and after the elimination of Staphylococcus aureus genotype B (SAGTB). Data on intramammary antibiotic use was collected in 65 dairy farms as part of a pilot project for SAGTB elimination in the canton of Ticino from 2017 to 2019. The investigated farms were divided into 46 affected farms (with at least one SAGTB-positive animal) and 19 control farms (SAGTB-free farms). Data on antibiotic use were requested from veterinarians and treatment incidence, as a measure of antibiotic use, was calculated based on medical records and veterinary prescriptions. In addition, the treatment incidence was calculated for 47 farms during alpine farming period. In 2018 (elimination year), the mean incidence of treatment during lactation in the SAGTB-positive farms was significantly higher than in the control farms (p=0,003). In 2019 no significantly lower antibiotic use during lactation or dry period was detected between 2017 (before elimination) and 2019 (after elimination). Alpine farming places where only S. aureus genotype B-negative animals had access to had a significantly lower antibiotic use during lactation (p=0,004). The new federal database (Antibiotics Information System in Veterinary Medicine, IS ABV) should allow continuous monitoring and to confirm the reduction of antibiotic use in the coming years.

Abstract
INTRODUCTION The use of antibiotics in Swiss veal production is considered an established method for controlling bacterial infectious diseases. Although the veterinary profession aims to ensure animal welfare, the veterinary business income needs to be ensured at the same time. Against the background of increasing problems with resistant pathogens in human and veterinary medicine, the use of antibiotics should be significantly reduced and used more selectively. The associated economic consequences for food animal practitioners are unknown. The aim of this study was to determine the economic importance of antibiotic sale volume for private food animal practitioners in veal production. An anonymized questionnaire was sent to 120 mixed veterinary practices in Switzerland, which offered services to veal and beef cattle farmers. Questions involved the pharmaceutical sale volume, details on veterinary invoices from three farms with average, below and above average animal health throughout 2017. Twenty-nine complete questionnaires (response rate: 24.2%) and veterinary invoices of 84 farms were returned. The study is not representative, but it allows a rough assessment of the economic framework in Swiss livestock practice. The majority of the total turnover with livestock farms was generated by the sale of antibiotics (54%). Antibiotic sales per animal were higher as expected in farms with a below-average animal health than in farms with an average or above-average animal health. Consulting services turnover contributed only 0.5% to the total sale volume in veal farming. The results document, that antibiotic reduction measurements in veal and beef production will have economic consequences for veterinary livestock practices. In the medium term, the profitable existence of livestock veterinary practice requires a change to cost based consulting services.

Abstract
It has been shown that the accuracy of mammographic abnormality detection methods is strongly dependent on the breast tissue characteristics, where a dense breast drastically reduces detection sensitivity. In addition, breast tissue density is widely accepted to be an important risk indicator for the development of breast cancer. Here, we describe the development of an automatic breast tissue classification methodology, which can be summarized in a number of distinct steps: 1) the segmentation of the breast area into fatty versus dense mammographic tissue; 2) the extraction of morphological and texture features from the segmented breast areas; and 3) the use of a Bayesian combination of a number of classifiers. The evaluation, based on a large kappa = 0.81 and 0.67 for the two data sets) between automatic and expert-based Breast Imaging Reporting and Data System mammographic density assessment.

Abstract
AIM To evaluate the influence of distinguishing between well and poorly differentiated nonfunctioning neuroendocrine pancreatic carcinomas (PC). METHOD Six well differentiated and 11 poorly differentiated nonfunctioning neuroendocrine PC were retrospectively analyzed for differences and compared with 340 ductal PC. RESULTS 1. There was no difference in pT categories between well differentiated and, poorly differentiated nonfunctioning neuroendocrine PC and ductal PC. 2. The rate of the pN1 category was lower in well differentiated lesions (20%) than in poorly differentiated lesions (66%) and in the ductal PC group (75%). 3. The outcome of patients with R0 resections was significantly better for well differentiated neuroendocrine PC with all patients alive than for poorly differentiated ones and for ductal PC (5-year survival rate 0% and 18%, respectively). 4. The outcome following R1/R2 resections for poorly differentiated neuroendocrine PC tended to be similar than for ductal PC (1-year survival rate 20% vs. 33%). 5. There was no difference in mean survival time (9 months) between poorly differentiated lesions and ductal PC after palliative procedures. CONCLUSIONS The better outcome of surgical treatment of nonfunctioning neuroendocrine PC vs. that of ductal PC was confined to well differentiated neuroendocrine lesions. For poorly differentiated lesions the outcome was as poor as for ductal PC. These results underscore the importance to distinguish between well and poorly differentiated nonfunctioning neuroendocrine PC.

Abstract
This multicenter randomized phase III study was designed to compare the efficacy and toxicity of IFN alpha-2c (3.5 MU/d) in combination with either araC (10 mg/m(2) d1-10) or hydroxyurea (HU: 25 mg/kg per day) in newly diagnosed CML patients. A total of 114 patients were randomized. Following a median observation period of 36 (range 1-73) months the major cytogenetic response rates were 25 and 27% and the 4-year survival probabilities 62.5 and 63% for the araC and HU group, respectively. While the overall toxicity profile was comparable between both groups, patients in the HU arm exhibited a slightly higher degree of WHO grades 3 and 4 non-hematological toxicities.

Abstract
BACKGROUND This investigation evaluates prognostic variables in patients with seminomatous and non-seminomatous extragonadal germ-cell tumors (EGCT) in order to identify relevant factors for long-term outcome following cisplatin-based chemotherapy. PATIENTS AND METHODS Patients from six countries treated at 11 centers in Europe and the USA from 1975 to 1996 were evaluated retrospectively. Uni- and multivariate analyses of prognostic variables for survival and for response to chemotherapy were performed. RESULTS Data were available for 635 EGCT patients, 104 with seminomatous and 524 with non-seminomatous EGCT (n = 7 not specified). For non-seminomatous EGCT the following independent adverse factors were identified: presence of either liver, lung or central nervous system metastases, primary mediastinal tumor or elevation of pretreatment beta-human gonadotropin; for extragonadal seminoma (only univariate) adverse factors were: presence of liver metastases, two or greater metastatic sites or International Germ Cell Cancer Collaborative Group (IGCCCG) grouping (intermediate versus good). Integration of these variables produced the following prognostic risk groupings: 'excellent prognosis', all seminomatous EGCT (89% 5-year survival rate); 'intermediate low', 'intermediate high' and 'poor', all non-seminomatous EGCT with a 69, 55 and 17% 5-year survival rate, respectively. The decreased survival among the different groups was due to a lower rate of favorable objective remissions and a higher rate of relapses. Classification and regression tree (CART) modeling confirmed histology and location of primary tumor as the major prognosticators. For the subgroup of patients with mediastinal non-seminoma, the 2-year survival rate ranged from 34 to 84%. Multivariate testing for the probability to respond to chemotherapy revealed non-seminomatous histology, primary mediastinal tumor site, and the presence of liver, lung or CNS metastases as independent adverse factors. CONCLUSIONS In EGCT, prognostic variables for the outcome and for the response to chemotherapy could be identified, which in part differ from gonadal GCT. The proposed model might help to better understand the specific prognosis of EGCT and to tailor risk-adapted treatment strategies. In addition, CART analysis demonstrated the heterogenous prognosis of patients with mediastinal non-seminoma.

Abstract
BACKGROUND Alternative and effective drug regimens in patients with metastatic breast cancer progressing after adriamycin- and taxoid-containing regimens are urgently needed. PATIENTS AND METHODS In a phase II trial, 43 heavily pretreated patients with metastatic breast cancer were treated with both carboplatin 200 mg/m(2) i.v. and mitomycin C 10 mg/m(2) i.v. on day 1 every 4 weeks. In case of granulocytopenia or thrombocytopenia below grade 3 according to NCI-CTC, the carboplatin dosage was escalated to 300, 400, and 450 mg/m(2) in the next treatment cycle. RESULTS During the first 3 cycles the dose intensity of carboplatin could be increased from a mean of 50 to 74 mg/m(2)/week. Beyond this value the carboplatin dose intensity decreased because of hematotoxicity. Based on an intention-to-treat analysis, 9 of 43 patients responded to therapy (21%; 95% CI = 10.04-36.04) including 2 complete and 7 partial responses. 15 patients had no change, 13 progressed, and 6 patients were considered nonevaluable. The median time to progression was 3 (range 0-12) months. NCI-CTC grade 3 or 4 granulocytopenia was observed in 14 patients, grade 3 or 4 thrombocytopenia occurred in 32, grade 3 infections in 3, grade 3 hemorrhage in 1, and grade 3 cardiac dysrhythmias in 1 of the patients. CONCLUSIONS In anthracycline/ taxoid-pretreated patients, salvage treatment with a combination of carboplatin and mitomycin C seems to be effective and associated with foreseeable toxicity. Based on our results with an intraindividual dose escalation of carboplatin, a dosage of 300 mg/m(2) in combination with mitomycin C 10 mg/m(2) every 4 weeks seems to represent a recommendable starting dose for future studies.

Abstract
BACKGROUND The frequency of subsequent testicular cancer (referred to as metachronous testicular cancer) in men who have had previous testicular cancer is relatively high. The rate of metachronous testicular cancer in men with extragonadal germ cell tumors (EGCTs), however, is largely unknown. We conducted a retrospective study of EGCT patients to determine the incidence, cumulative risk, and specific risk factors for metachronous testicular cancers. METHODS A standardized questionnaire about patient characteristics, the extent of EGCT disease, any second malignancies, and treatments received was completed for 635 patients with EGCTs identified from the medical records of 11 cancer centers in Europe and the United States from 1975 through 1996. Comparisons with age group-specific data from the Saarland, Germany, population-based cancer registry were used to calculate the standardized incidence ratio (SIR). The Kaplan-Meier method was used to analyze survival data and cumulative risk. All statistical tests were two-sided. RESULTS Sixteen EGCT patients (4.1%) developed metachronous testicular cancers, with a median time between diagnoses of 60 months (range, 14-102 months). The risk of developing metachronous testicular cancers was statistically significantly increased in patients with EGCTs (observed = 16; expected = 0.26; SIR = 62; 95% confidence interval [CI] = 36 to 99) and in subsets of EGCT patients with mediastinal location (SIR = 31; 95% CI = 8 to 59), retroperitoneal location (SIR = 100; 95% CI = 54 to 172), and nonseminomatous histology (SIR = 75; 95% CI = 43 to 123). The cumulative risk of developing a metachronous testicular cancer 10 years after a diagnosis of EGCT was 10.3% (95% CI = 4.9% to 15.6%) and was higher among patients with nonseminomatous EGCTs (14.3%; 95% CI = 6.7% to 21.9%) and retroperitoneal EGCTs (14.2%; 95% CI = 5.6% to 22.8%) than among patients with seminomatous EGCTs (1.4%; 95% CI = 0.0% to 4.2%) and mediastinal EGCTs (6.2%; 95% CI = 0.1% to 12.2%). CONCLUSIONS Patients with EGCTs, particularly those with retroperitoneal or nonseminomatous tumors, but also those with primary mediastinal EGCTs, are at an increased risk of metachronous testicular cancer.

Abstract
The present analysis was performed to evaluate the impact of cytosine arabinoside (ara-C) dose escalation on hematological and cytogenetic responses in patients with chronic myelogenous leukemia (CML) who failed to respond to low-dose ara-C (LD ara-C) at a dose of 10 mg/m2/d over 10 days per month and interferon-alpha (IFNalpha, 3.5 MU/d). Following the same administration schedule, dose escalation of ara-C to 15 and 20 mg/m2/d 1-10 was performed in 36 of 119 patients (30%) due to inadequate hematological response and/or disease progression. As a result, improvement of hematological and cytogenetic responses was achieved in 22 (61%) and nine (25%) patients, respectively. Escalated ara-C dose levels were usually well tolerated, although some patients experienced deterioration of preexisting side effects. Our results support the critical role of ara-C dose towards a better disease control in CML.

Abstract
The majority of lymphomas of the mucosa-associated lymphoid tissue (MALT)-type arise in the stomach, but extragastric locations are also frequently encountered. Due to previous results indicating that somatostatin receptor (SSTR)-expression distinguishes between gastric and extragastric MALT-type lymphoma, we have initiated a study to evaluate the role of SSTR-scintigraphy for staging and follow-up of patients with extragastric manifestations of MALT-type lymphoma. A total of 30 consecutive patients, including 24 with primary extragastric MALT-type lymphoma, 5 patients with dissemination to extragastric sites (including colon, lung, parotid, ocular adnexa and breast) following an initial gastric MALT-lymphoma and one patient with spread to stomach, lung and lymph nodes following parotid lymphoma were prospectively studied. All patients had histologically verified MALT-type lymphoma: 2 patients had lymphoma presenting in the lung, 9 in the ocular adnexa, 7 had lymphomas in the parotid, 2 patients had disease located in the breast, 3 patients had lymph-node relapse following MALT-type lymphoma of the parotid, the lacrimal gland and the thyroid, and 1 had primary MALT-lymphoma of the liver. All patients underwent SSTR-scintigraphy using (111)In-DTPA-D-Phe(1)-Octreotide ((111)In-OCT) before initiation of therapy, while 13 also had a second scan after treatment. The results of gamma camera imaging were compared to conventional staging. No positive scans could be obtained in patients with dissemination following gastric lymphoma, while all patients with primary extragastric lymphoma had positive scans at the site of histologically documented involvement before initiation of therapy. In addition, also the patient with secondary spread to stomach, lung and lymph nodes was positive in all documented lymphoma sites. In one patient, focal tracer uptake in projection to the maxillary sinus was documented, which was bioptically verified as inflammation. In the scans performed after therapy, focal tracer accumulation in the left orbit indicated persistence of disease following irradiation in one patient with otherwise negative work-up, which was verified by MRI and biopsy 6 months later. In another patient, a positive scan indicated disease relapse in the lacrimal gland 9 months before clinical verification by means of ultrasound. In one patient, a focus not present in the pretherapeutic scan was found in the ethmoidal sinus, corresponding to a hyperplastic polyp. Both SST-scan as well as CT indicated disease persistence in one case, while negative scans corresponding to complete remission as judged by conventional staging were obtained following therapy in the remaining patients, and absence of relapse has been confirmed for a median follow-up of 2 years. These results indicate that (111)In-OCT is an excellent tool for staging and non-invasive therapy-monitoring in extragastric MALT-type lymphomas. These data further confirm our initial finding that gastric MALT-type lymphomas do not express relevant amounts of respective SSTR, and that SSTR-scanning is able to distinguish between gastric vs extragastric origin of MALT-type lymphoma irrespective of the site of presentation.

Abstract
PURPOSE To establish the predictive potential of 2-18fluoro-2-deoxy-D-glucose positron emission tomography (FDG PET) for detecting viable tumor tissue in residual postchemotherapy masses of seminoma patients. PATIENTS AND METHODS In this prospective multicenter trial, results of FDG PET studies in seminoma patients with postchemotherapy masses > or = 1 cm were correlated with either the histology of the resected lesion or the clinical outcome on follow-up without resection. Negative PET scans of residual lesions that were devoid of viable tumor tissue on resection or disappeared, shrunk, or remained stable in size for at least 2 years were rated as true-negative (TN). Positive scans without histologic or clinical evidence of tumor tissue were classified as false-positive. In patients with histologically positive or progressive lesions, positive PET scans were defined as true-positive (TP) and negative scans, false-negative (FN). RESULTS Thirty-seven PET scans of 33 patients were assessable at a median follow-up time of 23 months (range, 2 to 46 months). Histologic data were available from nine patients who had undergone resection. Twenty-eight patients were followed-up clinically and radiologically. Twenty-eight scans were TN, eight were TP, and one was FN. All 14 residual lesions more than 3 cm and 22 (96%) of the 23 < or = 3 cm were correctly predicted by FDG PET. The specificity (100%; 95% confidence interval [CI], 87.7% to 100%), sensitivity (89%; 95% CI, 51.7% to 99.7%), positive predictive value (100%), and the negative predictive value (97%) of FDG PET were superior to data obtained by assessing residual tumor size (< or = or > 3 cm). CONCLUSION FDG PET is a clinically useful predictor of viable tumor in postchemotherapy residuals of pure seminoma, especially those greater than 3 cm.

Abstract
PURPOSE: To assess the value of postsurgery chemotherapy in patients with disseminated nonseminomatous germ-cell tumors (NSGCTs) and viable residual disease after first-line cisplatin-based chemotherapy. PATIENTS AND METHODS: The outcome of 238 patients was reviewed. Tumor markers had normalized in all patients before resection. A multivariate analysis of survival was performed on 146 patients. RESULTS: The 5-year progression-free survival (PFS) rate was 64% and the 5-year overall survival (OS) rate was 73%. Three factors were independently associated with both PFS and OS: complete resection (P < .001), < 10% of viable malignant cells (P = .001), and a good International Germ Cell Consensus Classification (IGCCC) group (P = .01). Patients were assigned to one of three risk groups: those with no risk factors (favorable group), those with one risk factor (intermediate group), and those with two or three risk factors (poor-risk group). The 5-year OS rate was 100%, 83%, and 51%, respectively (P < .001). The 5-year PFS rate was 69% (95% confidence interval [CI], 62% to 76%) and 52% (95% CI, 40% to 64%) in postoperative chemotherapy recipients and nonrecipients, respectively (P < .001). No significant difference was detected in 5-year OS rates. After adjustment on the three prognostic factors, postoperative chemotherapy was associated with a significantly better PFS (P < .001) but not with better OS. Patients in the favorable risk group had a 100% 5-year OS, with or without postoperative chemotherapy. Postoperative chemotherapy appeared beneficial in both PFS (P < .001) and OS (P = .02) in the intermediate-risk group but was not statistically beneficial in the poor-risk group. CONCLUSION: A complete resection may be more critical than recourse to postoperative chemotherapy in the setting of postchemotherapy viable malignant NSGCT. Immediate postoperative chemotherapy or surveillance alone with chemotherapy at relapse may be reasonable options depending on the completeness of resection, IGCCC group, and percent of viable cells. Validation is necessary.

Abstract
BACKGROUND The objectives of this study were to evaluate the long term outcome of patients with extragonadal seminomatous germ cell tumors (GCT) so that prognostic variables for disease recurrence and patient survival could be identified and to access the efficacy of different treatment modalities. METHODS Six hundred thirty-five patients with extragonadal GCT who were treated consecutively at 11 centers in the United States and Europe during the cisplatin-based chemotherapy era between 1975 and 1996 were evaluated retrospectively. RESULTS Fifty-two patients with primary retroperitoneal GCT (50%) and 51 patients with primary mediastinal GCT (49%) of pure seminomatous histology were identified (n = 1 patient with a primary cervical lymph node) representing 16.4% of 635 patients with extragonadal GCT who were included in the data base. The median age was 37 years (range, 18-70 years). Treatment consisted of platin-based chemotherapy in 77 patients (74%), radiotherapy in 9 patients (9%), and combined modality in 18 patients (17%). Ninety-two percent of patients (95% confidence interval, 87-97%) achieved a favorable response to primary therapy. After a median follow-up of 61 months (range, 1-211 months), 18 patients (17%) have had recurrent disease: 14% of those who received chemotherapy and 67% of those who received radiation therapy. The 5-year progression free survival rate favored the chemotherapy group, with 87% compared with 33% for irradiated patients (P = 0.006), whereas the overall survival rates were equal (90% vs. 67%; P = 0.13). No differences in overall survival or progression free survival were observed among patients with primary retroperitoneal and mediastinal seminoma. Prognostic factors that were identified to influence survival negatively were liver metastases (P = 0.01) and two or more metastatic sites (P = 0.04). CONCLUSIONS In patients with extragonadal seminoma, a survival rate of > 90% at 5 years is achieved with adequate cisplatin-based chemotherapy. Compared with patients with nonseminomatous extragonadal GCT, no difference in long term survival exists between patients with primary retroperitoneal or mediastinal seminoma location. Primary radiotherapy seems to be associated with a significantly higher rate of disease recurrence, although most patients will be salvaged by subsequent chemotherapy.

Abstract
PURPOSE Relapsed extragonadal germ cell tumors patients (EGGCT) are treated with identical salvage chemotherapy regimens, as are patients with metastatic testicular cancer. This investigation evaluates the results of second-line chemotherapy in nonseminomatous EGGCT and tries to identify prognostic factors for survival. PATIENTS AND METHODS We conducted a retrospective review of 142 patients treated at eleven European and American centers between 1975 and 1996. All had received cisplatin-containing regimens as induction treatment. RESULTS Twenty-seven of 142 patients (19%) were long-term disease-free, 11% with primary mediastinal and 30% of patients with primary retroperitoneal disease. Median follow-up since start of salvage treatment was 11 months (range, 1 to 157) for all patients and 45 months (range, 6 to 157) for surviving patients. Forty-eight patients (34%) received high dose chemotherapy with autologous bone marrow transplant at relapse, and 10 of these patients (21%) are continuously disease-free. Primary mediastinal location (P =.003), sensitivity to cisplatin (P =.003), elevated beta-HCG at relapse (P: =.04), and normal LDH at diagnosis (P =.01) were shown to be significant negative prognostic factors for overall survival in univariate; mediastinal location [relative risk ratios (HR) = 1.9; 95% confidence intervals (CI), 1.2 to 3.0] and sensitivity to cisplatin [HR = 2.4; 95% CI, 1.1 to 5.2] were significant negative prognostic factors in multivariate analysis. CONCLUSION Although current salvage strategies will cure between 20% and 50% of recurrent metastatic testicular cancer, relapsed nonseminomatous EGGCT patients appear to have an inferior survival rate, in particular in case of primary mediastinal location. Mediastinal primary tumor and inadequate response to cisplatin-based induction chemotherapy have been identified as independent negative prognostic factors, both associated with an approximately two-fold higher risk for failure of salvage treatment.

Abstract
BACKGROUND & AIMS Appropriate management of primary gastric lymphoma is controversial. This prospective, multicenter study aimed to evaluate the accuracy of endoscopic biopsy diagnosis and clinical staging procedures and assess a treatment strategy based on Helicobacter pylori status and tumor stage and grade. METHODS Of 266 patients with primary gastric B-cell lymphoma, 236 with stages EI (n = 151) or EII (n = 85) were included in an intention-to-treat analysis. Patients with H. pylori-positive stage EI low-grade lymphoma underwent eradication therapy. Nonresponders and patients with stage EII low-grade lymphoma underwent gastric surgery. Depending on the residual tumor status and predefined risk factors, patients received either radiotherapy or no further treatment. Patients with high-grade lymphoma underwent surgery and chemotherapy at stages EI/EII, complemented by radiation in case of incomplete resection. RESULTS Endoscopic-bioptic typing and grading and clinical staging were accurate to 73% and 70%, respectively, based on the histopathology of resected specimens. The overall 2-year survival rates for low-grade lymphoma did not differ in the risk-adjusted treatment groups, ranging from 89% to 96%. In high-grade lymphoma, patients with complete resection or microscopic tumor residuals had significantly better survival rates (88% for EI and 83% for EII) than those with macroscopic tumor residues (53%; P < 0.001). CONCLUSIONS There is a considerable need for improvement in clinical diagnostic and staging procedures, especially with a view toward nonsurgical treatment. With the exception of eradication therapy in H. pylori-positive low-grade lymphoma of stage EI and the subgroup of locally advanced high-grade lymphoma, resection remains the treatment of choice. However, because there is an increasing trend toward stomach-conserving therapy, a randomized trial comparing cure of disease and quality of life with surgical and conservative treatment is needed.

Abstract
BACKGROUND Apart from a recognized association between extragonadal mediastinal germ cell tumors (GCT) and the occurrence of hematologic malignancies, the risk of developing second nongerminal solid tumors after the diagnosis or treatment of extragonadal GCT is unknown. METHODS Six hundred thirty-five consecutive patients with extragonadal GCT treated at 11 centers in the U.S. and Europe during the era of cisplatin-based chemotherapy (1975-1996) were included into a large database. These patients were evaluated for the occurrence of second malignancies. RESULTS No treatment-related leukemia was observed in 611 patients treated with chemotherapy. In 7 patients, second solid tumors were observed, resulting in a frequency of 1.86% (95% confidence interval [95% CI], 1.79-1.93%) after a median follow-up of 55 months (95% CI, 50-60 months) (annual incidence, 0.30% [95% CI, 0.14-0.59]). Four solid tumors (57%) developed in patients with primary mediastinal and 3 tumors (43%) developed in patients with retroperitoneal GCT. Three patients (43%) had a nonseminomatous and 4 patients (57%) had a seminomatous histology. Six patients had been treated with chemotherapy and one patient with radiotherapy. Six of 7 solid tumors (86%) had developed within 5 years and 7 of 7 solid tumors within 10 years of diagnosis. The median time period to the occurrence of neoplasia was 47 months (range, 9-145 months). Four cutaneous tumors were observed (melanoma, two patients; basal cell carcinoma, one patient; and squamous cell carcinoma, one patient); the other three tumors were angiosarcoma, nonsmall cell lung carcinoma, and colorectal carcinoma. The overall risk for developing a second tumor was not increased compared with an age-matched general population with a standard incidence ratio (SIR) of 1.49 (95% CI, 0.60-3.06). An elevated risk for skin tumors was observed in all extragonadal GCT patients (SIR, 4.00 [95% CI, 1. 09-10.24]), as well as in the subgroup of patients treated with chemotherapy (SIR, 5.33 [95% CI, 1.45-13.65]). CONCLUSIONS This analysis excludes an increased biologic risk of developing second solid malignancies in patients with extragonadal GCT except for the previously reported association between primary mediastinal nonseminoma and hematologic disorders. The overall risk of developing second malignancies in extragonadal GCT patients appears to be comparable to that in patients with primary testicular carcinoma. The incremental occurrence of skin malignancies in patients treated with chemotherapy should be investigated further.

Abstract
BACKGROUND The association between primary germ cell tumors of the mediastinum (the space between the lung pleura that contains the heart and other chest viscera) and hematologic malignancies has been described by retrospective analysis of patients treated at individual clinical centers. To better characterize the risk of hematologic disorders in patients with extragonadal germ cell tumors and to describe the clinical and biologic features of the disorders, we studied an unselected population in a large, international, multicenter database. METHODS Six hundred thirty-five patients treated at 11 centers in the United States and Europe from 1975 through 1996 were evaluated retrospectively. RESULTS A hematologic disorder was observed in 17 patients with germ cell tumors. All cases developed among the 287 patients with primary mediastinal nonseminomatous germ cell tumors, giving an incidence rate in this group of 2.0% (95% confidence interval [CI] = 1.1%-3.1%) per year over a median follow-up time of 3 years. The risk of developing hematologic disorders was statistically significantly increased in patients with primary mediastinal nonseminomatous germ cell tumors in comparison with the age-matched general population (standardized incidence ratio = 250; 95% CI = 140-405). The median time to onset of hematologic neoplasia was 6 months (range, 0-47 months), and the median survival after diagnosis of the hematologic disorder was 5 months (range, 0-16 months) (two-sided P<.0001, comparing survival from the time of diagnosis of the germ cell tumor of patients with and without hematologic disorders). CONCLUSION In our study, approximately one in 17 patients with primary mediastinal nonseminomatous germ cell tumors was affected by a hematologic disorder, whereas no cases were seen among 334 patients with other extragonadal germ cell tumors. The hematologic disorder had a statistically significant impact on prognosis, with none of the 17 reported patients surviving for more than 2 years.

Abstract
More than half of the patients with testicular germ-cell cancer show impaired spermatogenesis before undergoing cytotoxic treatment. The known pre-treatment infertility and the reversibility of the fertility problems observed in some after successful anti-cancer treatment have so far prevented an assessment of the true role of cytotoxic therapy in long-term fertility. The introduction of wait-and-see strategies (surveillance) for testicular cancer patients and recent prospective trials comparing patients with and without cytotoxic treatment have provided the means for estimating the extent to which treatment itself affects long-term fertility. Whether or not spermatogenesis is irreversibly impaired by chemotherapy is determined by the cumulative dose of cisplatin: at doses below 400 mg/m2, long-term effects on sperm production as well as on endocrine function are unlikely to occur. Higher doses should be expected to cause long-term losses of exocrine and endocrine gonadal function. In contrast, for adjuvant retroperitoneal radiotherapy in stage I seminoma patients, no data are available comparing long-term gonadal function with patients on surveillance. However, using modern radiation techniques, radiation doses to the para-aortic field (< 30 Gy) and testis shielding providing testis scatter radiation (< 30 cG), radiation-induced impairment of fertility is very unlikely.

Abstract
BACKGROUND Multiinstitutional experience with the management of cerebral metastases from malignant germ cell tumors (MGCT) is presented. METHODS Clinical data regarding brain metastases from MGCT at diagnosis (Group 1 [56 patients]) or after cisplatin-based chemotherapy (Group 2 [83 patients]) were collected retrospectively. All patients in Group 1 received "conventional" cisplatin-based chemotherapy supplemented by cerebral radiotherapy (36 patients) and/or neurosurgery (10 patients). In the patients in Group 2 cerebral metastases were detected a median of 9 months after the initiation of chemotherapy. Thirty-five patients received chemotherapy, 59 patients received radiotherapy, and 25 patients underwent neurosurgery. RESULTS The 5-year cause specific survival rate in Group 1 was 45% (95% confidence interval [CI], 31-59%). Neurosurgery and the absence of extracerebral, nonpulmonary visceral disease, but not cerebral radiotherapy, were independent predictors of good prognosis. The 5-year cause specific survival rate in Group 2 was 12% (95% CI, 4-20%), but was 39% among patients with an isolated brain recurrence (24 patients). Radiotherapy, but not chemotherapy, represented an independent predictor of good prognosis together with brain metastases at first recurrence and the absence of extracerebral recurrence. CONCLUSIONS Among patients with brain metastases at the time of diagnosis of an MGCT, cisplatin-based chemotherapy resulted in a 5-year cause specific survival rate of 45%, with cerebral radiotherapy having limited impact. The 5-year cause specific survival rate for all patients with brain metastases after cisplatin-based chemotherapy was 12%, but increased to 39% in patients with an isolated brain recurrence. Cerebral radiotherapy (and neurosurgery) represent essential treatment modalities for patients in whom brain metastases are diagnosed after induction chemotherapy.

Abstract
It is well known that peptide-producing endocrine tumours cosecrete immunoreactive chromogranin A with their characteristic hormones. Into this study 187 patients with the diagnosis malignant carcinoids or other malignancies were entered. Using chromogranin A at a cut-off level of 30.3 U/ml it was possible to discriminate between patients in remission and patients suffering a relapse with a sensitivity of 91.7% and a specificity of 96.4%, which may be of important diagnostic value. In our study that lasted over one year we could clearly show that the measurement of chromogranin A is impressively superior to 5-hydroxyindoleacetic-acid for detecting a relapse of carcinoids.

Abstract
The present retrospective analysis is based on data of 213 patients with chronic myeloid leukaemia (CML). They were treated with interferon (IFN)alpha-2C (Berofor) at daily doses of 3.5 MU subcutaneously (s.c.), alone or in combination with low-dose ara-C or hydroxyurea, according to four consecutive studies of the Austrian CML Study Group. Comparisons were made between 41 patients aged > or = 60 years and 172 younger patients. The elderly patients (median: 64 years; range: 60-73) showed similar pretreatment characteristics compared with the younger group, but included a higher percentage of Sokal Stage three (51 vs 20%). Median observation periods were similar (38 vs 39 months), whereas the duration of IFNalpha treatment was shorter in the elderly group (median 57 vs 42 weeks). The rate of overall haematological responses (73 vs 78%) and complete haematological response (44 vs 54%), was similar in both cohorts. Differences seen in partial (5 vs 12%) and complete cytogenetic response (10 vs 13%), were not statistically significant, but a tendency in favour of the younger cohort had to be noted. Summing up, in elderly patients acceptable rates of haematological and cytogentic response can be expected after treatment with IFNalpha alone or in combination with LD ara-C or HU.

Abstract
We report a case of a 66-year-old white woman with calcium pyrophosphate dihydrate (CPPD) crystal deposition disease. The patient related a 2-month history of swelling with tenderness over the left pre-auricular region. A CT scan suggested a synovial chondromatosis. Surgical removal was done and histologic study showed CPPD crystals. This disease rarely involves the temporomandibular joint (TMJ) and is not usually considered in the differential diagnosis. To our knowledge, only 14 cases have been reported in the literature.

Abstract
BACKGROUND In most patients with advanced refractory germ cell tumors undergoing high-dose chemotherapy with stem cell support (HDCT) the disease progresses after HDCT. This study was designed to shed light on the unestablished role of post-HDCT chemotherapy. PATIENTS AND METHODS In a retrospective multicenter study data of 47 evaluable patients from nine centers subjected to post-HDCT chemotherapy for progression of their germ cell tumors were collected in a questionnaire survey and analyzed for treatment response and survival. RESULTS Of 191 patients pretreated by HDCT, 48 (25%) were subjected to post-HDCT chemotherapy for disease progression. Remission was achieved in 17 (36%) and marker-negative remission in eight (17%). The median survival time was 26 weeks, 65 weeks for responders and 13 weeks for non-responders. Only one of 47 evaluable patients achieved sustained complete remission. Remissions significantly correlated with the post-HDCT interval, the use of ifosfamide and the combination regimens of cisplatin + etoposide i.v. or ifosfamide and of paclitaxel + ifosfamide or cisplatin. On univariate analysis a longer post-HDCT interval, the use of cisplatin, paclitaxel and ifosfamide and the combined use of paclitaxel + ifosfamide and/or cisplatin significantly improved the chances of survival. On multivariate analysis only treatment with paclitaxel and ifosfamide retained independent prognostic significance for survival. CONCLUSIONS One third of the patients considered to be candidates for further chemotherapy once progressive after HDCT went into remission with a gain in survival time. Sustained remissions may occur, but are rarely seen. Paclitaxel and ifosfamide appear to be the most effective drugs in these heavily pretreated patients.

Abstract
High-dose chemotherapy (HDCT) is a promising treatment for patients with germ cell tumours and a poor prognosis. The selection of patients who may profit from this intervention is challenging for the urologist, as the indication has to be carefully established. Exclusion criteria primarily concern impaired organ functions. Prior to HDCT haematopoietic stem cells are obtained after the administration of conventional-dose chemotherapy plus G- or GM-CSF stimulation. HDCT consists of a combination of carboplatin, etoposide and ifosfamide or cyclophosphamide. After HDCT, haematologic monitoring and maximal supportive care are essential. It is therefore recommended that HDCT only be administered at specialized centres.

Abstract
Primary end point of this trial was to reduce neutropenic infections during the treatment of aggressive NHL with CEOP/IMVP-Dexa (cyclophosphamide, epirubicin, vincristine, prednisolone ifosfamide, methotrexate, VP-16, and dexamethasone). Further, we studied the influence of filgrastim on dose intensity of CEOP/IMVP-Dexa, on the rate of complete remissions, on the time to relapse, and on survival. Eighty-five patients with untreated large-cell NHL were randomized to one of two treatment arms; 74 patients were eligible. Thirty-eight patients in arm 1 were treated with CEOP/IMVP-Dexa chemotherapy and filgrastim, 36 in arm 2 with CEOP/IMVP-Dexa chemotherapy alone. In arm 1 filgrastim was self-injected by the patients at 5 micrograms/kg body wt. s.c. daily, except on the days when cytotoxic drugs were given. During treatment we did weekly complete blood counts. Median leukocyte counts were 10.91 x 10(9)/l and 5.46 x 10(9)/l in arm 1 and 2, respectively (p = 10(-6)). Median neutrophil counts were 7.7 x 10(9)/l in arm 1 and 2.72 x 10(9)/l in arm 2 (p < 10(-6)). Median neutrophil nadirs were 0.199 x 10(9)/l and 0.213 x 10(9)/l in arm 1 and 2, respectively (p = 0.09). Mean platelet nadirs were 95 and 152 x 10(9)/l (p = 0.000004) and mean hemoglobin nadirs 83.95 g/l and 92.78 g/l (p = 0.00558) in arm 1 and 2, respectively. Dose intensity of CEOP/IMVP-Dexa was 82.3% and 76.2% in arm 1 and 2, respectively (p = 0.041). Forty-two percent and 58% of patients experienced a febrile neutropenia in arm 1 and 2, respectively (not significant, NS). Median time to first neutropenic infection was in treatment week 11 and 6 in arm 1 and 2, respectively (NS). There was no significant difference in rate, duration, and kind of infection, duration of hospitalization, or antibiotic treatment. Seven toxic deaths occurred, all due to neutropenic infection, 6 and 1 in arm 1 and 2, respectively (p = 0.0732). Four of the six patients, who died of infection in arm 1 were older than 60 years. Complete remission rate was 83% and 66.7% in arm 1 and 2, respectively (NS). After a median observation time of 3 years there was no difference in time to relapse or survival. Filgrastim increases leukocyte and neutrophil counts and dose intensity, if used with CEOP/IMVP-Dexa chemotherapy in high-grade lymphomas. There was no significant effect on febrile neutropenia or infections. The more frequent fatal neutropenic infection rate in the filgrastim arm was not statistically significant. It is most appropriate to explain it by the patient's age in combination with the high dose intensity. The small increase in dose intensity had no effect on survival but probably decreased hemoglobin levels and platelet counts in arm 1. We were unable to show a benefit for filgrastim in combination with CEOP/IMVP-Dexa.

Abstract
OBJECTIVE To investigate the impact of cytostatic chemotherapy on long-term fertility in patients with testicular germ cell cancer. BACKGROUND Many patients with testicular germ cell cancer show impaired spermatogenesis before undergoing cytotoxic chemotherapy. The known infertility before treatment and the reversibility of the fertility problems observed in some of them after successful anticancer treatment so far have prevented an assessment of the true impact of chemotherapy on long-term fertility. The introduction of a wait-and-see strategy (surveillance) for patients with testicular cancer and recent prospective trials comparing patients with and without cytotoxic chemotherapy now have provided the means for estimating the extent to which chemotherapy itself affects long-term fertility. RESULT(S) Whether spermatogenesis is impaired irreversibly by chemotherapy is determined by the cumulative dose of cisplatin. At cumulative doses > 400 mg/m2, irreversible impairment of gonadal function should be expected. CONCLUSION(S) At cumulative cisplatin doses < 400 mg (equivalent to 4 courses of state-of-the-art treatment), chemotherapy is unlikely to cause irreversible damage to fertility.

Abstract
OBJECTIVE To evaluate the indications, techniques and outcome of organ-preserving tumour enucleation in patients with bilateral testicular germ cell tumours (BTGCT) rather than standard bilateral radical orchidectomy which results in loss of fertility and a lifelong requirement for androgen replacement. PATIENTS AND METHODS In 13 patients with BTGCT of 6-30 mm in diameter, the tumours were enucleated under cold ischaemia after inguinal testicular exploration, and biopsies of the tumour bed and the peripheral parenchyma were taken. Histology of the orchidectomy specimen revealed a seminoma in four cases, an embryonal carcinoma in three, a teratocarcinoma and a mixed-germ cell tumour in two each, and a mature teratoma in one. Histology of the enucleated tumours showed a seminoma in seven cases, an embryonal carcinoma in five and a mature teratoma in one. Six of the 13 patients underwent testicular radiation (20 Gy) for carcinoma in situ (CIS) and five patients had adjuvant local therapy. Six months postoperatively a testicular biopsy was taken to determine the success of therapy. RESULTS The median follow-up was 62 months (range 14-163) and the 13 patients are currently free of disease; one patient had local recurrence 9 months after tumour enucleation but after orchidectomy the patient is free of disease after a follow-up of 156 months. Serum concentrations of luteinizing hormone and testosterone were within the normal range in all patients and no androgen substitution was necessary. A testicular biopsy taken 6 months post-operatively revealed Sertoli cells only in all patients who had received radiation therapy. CONCLUSIONS These results suggest that organ-sparing surgery in patients with BTGCT represents a new therapeutic approach with endocrinological and psychological advantages. In our experience, enucleation resection of testicular tumours is possible with certain prerequisites, i.e. the tumour is organ-confined with no infiltration of the rete testis, multiple biopsies of the tumour bed and peripheral parenchyma should be taken, any associated CIS treated by radiation therapy, and patients must be followed closely.

Abstract
Small pilot studies of patients with CML have reported on encouraging response rates after treatment with interferon-alpha (IFNalpha) in combination with low-dose cytosine arabinoside (LD ara-C). We therefore initiated a multi-center phase II trial in order to investigate the efficacy and tolerability of this combination in newly diagnosed patients with Ph-positive chronic myelogenous leukemia (CML). Eighty-four patients were treated with IFN-alpha-2c at daily subcutaneous doses of 3.5 MU and LD ara-C added subcutaneously for 10 days every month at a dose of 10 mg/m2, following an initial reduction of WBC to less than 20 x 10(9)/l with hydroxyurea (HU). Within a median observation period of 28 (5-59) months the patients received a median of 7 (1-35) IFNalpha and LD ara-C cycles. Treatment was stopped due to side effects in 16 cases (19%) and to primary or secondary treatment failure in 38 cases (45%). In 45 patients (54%) complete hematological response (CHR) was achieved; in 39 patients (46%) cytogenetic responses including 15 (18%) complete cytogenetic responses (CHR) were observed. Median duration of cytogenetic responses was 15 months. Relapses were seen in 8/15 patients (53%) with complete cytogenetic remission (CCR), in 3/6 patients (50%) with partial cytogenetic response and in 9/18 patients (50%) with minor cytogenetic response. In conclusion, the combination of IFNalpha and LD ara-C resulted in encouraging rates of hematological and cytogenetic responses in patients with CML with low to moderate toxicity.

Abstract
PURPOSE To assess the impact of short-term adjuvant chemotherapy on relapse rates, treatment-related morbidity, and long-term toxicity in patients with clinical stage I nonseminomatous testicular germ cell tumor (NSGCT I) who carry a high risk of relapse, ie, who show blood-vessel invasion (VI) by the primary tumor. PATIENTS AND METHODS From January 1985 to January 1995, 42 NSGCT I patients with VI were treated with two courses of cisplatin, etoposide, and bleomycin (PEB) after orchidectomy. Of these, 29 patients with a follow-up time of more than 2 years are the subject of this report. NSGCT I patients without VI were assigned to a surveillance program and served as controls for the assessment of long-term toxicity. RESULTS During a median follow-up time of 79 months (range, 27 to 119), two patients relapsed. One developed fully differentiated mature teratoma; the other was a true chemotherapy failure and again developed embryonal carcinoma. Twenty-seven patients (93%) are alive without evidence of disease; one patient (3%) died of progressive testicular cancer and another of lung cancer. The two courses of PEB did not cause any severe acute adverse reactions. The assessment of late sequels of adjuvant chemotherapy based on clinical and laboratory evidence of cardiovascular and pulmonary disease, fertility, and secondary neoplasms, as well as on a psychosocial questionnaire, did not show any significant disadvantages versus the control group. CONCLUSION Adjuvant chemotherapy with two courses of PEB is an effective and reasonable treatment option for patients with clinical stage I NSGCT who carry a high risk of relapse. No adverse late sequelae were detected within a median follow-up time of more than 6 years.

Abstract
PURPOSE This trial evaluated the efficacy, toxicity, and practicability of a new intensive chemotherapy regimen in a multicenter setting of university and community hospitals. PATIENTS AND METHODS We tested a hybrid protocol of two non-cross-resistant regimens, cyclophosphamide, epirubicin, vincristine, and prednisolone (CEOP) and ifosfamide, etoposide (VP-16), methotrexate, and dexamethasone (IMVP-Dexa) given every fourth week, three to six times according to response, in patients with untreated intermediate- and high-grade non-Hodgkin's lymphoma. Ten Austrian centers entered 81 patients onto this multicenter trial. Eleven patients were excluded. The median age was 55 years. Twenty-six of 70 patients had stage III or IV disease. The distribution among international risk categories low, intermediate-low, intermediate-high, and high was 20%, 34%, 23%, and 23%, respectively. RESULTS Of 70 eligible patients, 56 (80%) had a complete remission and seven (10%) a partial remission. After a median observation time of 36 months, the estimated time to relapse and overall survival rates are 67% and 72%, respectively. Age and Karnofsky index were the only independent risk factors for survival. Toxicity was primarily hematologic, with a median granulocyte nadir of 0.56 x 10(9)/L. Sixty-seven percent of patients had infections; 25.7% were severe World Health Organization (WHO) grade III or IV. There were three treatment-related deaths. CONCLUSION CEOP-IMVP-Dexa chemotherapy is safe and feasible on a groupwide basis even when used in community hospitals. Neutropenic infections are the major complications. A 72% 3-year survival rate in patients with intermediate- and high-grade non-Hodgkin's lymphoma warrants further studies. These data are the basis for a randomized trial to compare cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) with CEOP/IMVP-Dexa.

Abstract
Three patients with persistent parvovirus B19 infection, as documented by the prolonged presence of IgM directed to the viral capsid proteins and detection of viral DNA in serum by dot-blot hybridization or polymerase chain reaction (PCR), were investigated for the presence of antibodies to the nonstructural protein NS-1 of parvovirus B19. This was done by using an ELISA based on recombinant NS-1 protein. Whereas control sera displayed no reactivity, sera from persistently infected patients showed a strong specific antibody response to NS-1. Patients were followed for 3-18 months, during which IgM titers declined but IgG directed to the nonstructural protein remained detectable. The appearance of NS-1-specific antibodies might indicate an altered course of viral infection leading to the establishment of persistently active infection and subsequent destruction of cells of nonerythroid lineage.

Abstract
In 1989, 1990 and 1992, 19%, 15% and 10%, respectively, of all prisoners newly admitted to prisons and penitentiary institutions in Austria underwent HIV antibody tests. Based on the HIV test outcome in prisons in which more than 80% of the newly admitted inmates were tested, annual HIV prevalences among prison inmates in Austria were determined. These were 0.5% (11/2,223), 1.3% (19/1,466) and 0.9% (14/1,509) in 1989, 1990 and 1992, respectively. The prevalence rates among prison inmates in Austria are thus 5 times higher than those in the general Austrian population. About 5% of all inmates belong to the high-risk group of intravenous drug users. Inquiries into HIV risk behavior among prison inmates showed that, in Austrian prisons just like in those of many other countries, intravenous drug use and sexual contacts are common practices. As disposable needles and condoms are not available to prison inmates, these practices carry a particularly high risk of HIV transmission. The data collected can be taken as a basis for developing strategies which are designed to reduce the risk of HIV transmission in prisons and which have a major bearing on the development of the HIV pandemic.

Abstract
Five patients with severe aplastic anaemia (SAA) who, simultaneously (n = 3) or consecutively (n = 2), presented with multiple sclerosis (MS) (n = 2) or immune hyperthyroidism (IHT) (n = 2) or subacute thyroiditis (n = 1) are described. Two female patients with MS developed SAA after a small dose of azathioprine. Another patient simultaneously presented with IHT and SAA. SAA and MS responded to cyclosporine while IHT required 131I. Relapsing SAA in 1 patient with MS was treated with antithymocyte globulin (ATG) which induced acute exacerbation of MS. Despite the low total dose of ATG (31.5 mg/kg), complete remission of SAA was obtained. Two other patients developed thyroid disorders, 42 and 106 months after successful immunosuppression with ATG/high-dose methylprednisolone. IHT and subacute thyroiditis were successfully treated with 131I or prednisolone, respectively, without recurrence of SAA in both cases. These are the first documented cases of SAA evolving in the course of MS while the coincidence with IHT was already described. Since enhanced expression of interferon-gamma plays a crucial role in SAA as well as in MS and in IHT, similar pathogenetic principles may apply for these seemingly unrelated disorders.

Abstract
The reverse transcriptase-polymerase chain reaction (RT-PCR) for the fusion transcript of PML-RAR alpha can be used to detect minimal residual disease (MRD) in acute promyelocytic leukemia (APL). We have applied a semi-quantitative two-step PCR assay (sensitivity: step 1 = 1 in 10(3) cells; step 2 = 1 in 10(6) cells) to monitor the dynamics of MRD after combined therapy with all-trans-retinoic acid (ATRA) and chemotherapy (CT) in 5 patients in whom complete clinical remission (CR) was achieved. The patients received an induction treatment with ATRA for 47, 40, 38, 14 or 10 days. In three patients ATRA was followed by CT. Two patients with hyperleukocytosis at diagnosis or after ATRA received an overlapping CT starting from day 3 or 7. Four of the five patients became two-step PCR-negative in their bone marrow within 43 to 82 days after onset of therapy. Two-step PCR-negatively was achieved with ATRA plus one course of CT in these four patients who are still in continuous complete remission after 19, 18, 7 and 5 months. One of these patients did not even receive consolidation CT because of congestive heart failure. The fifth patient remained second-step PCR-positive and relapsed after 5 months. Our results indicate that the combined regimen can rapidly reduce MRD below a detection limit of 1 in 10(6) cells within 1-3 months and that these results can even by achieved by a short course of ATRA together with only one cycle of CT.

Abstract
A needs survey was administered by mail in the Coalfields area of the Hunter region (a lower socioeconomic area around Cessnock) and in a higher socioeconomic area of Newcastle. The purpose was to assist planning for Coalfields Healthy Heartbeat--a community-action heart disease prevention program. Response rates from random samples of residents were 435/897 (49 per cent) for the Coalfields and 565/875 (65 per cent) for Newcastle. In both study areas heart attack was ranked eleventh from a list of 17 potential community worries, well below drugs, crime, road safety, the environment, cancer and 'loss of health'. Coalfields respondents were more worried about all issues on the list than were the residents in Newcastle and were less likely to have heard about recent health promotion campaigns. Coalfields respondents felt that heart disease prevention was the responsibility of the individual, the family, and the medical profession, in that order, and much less the responsibility of local community groups. Results suggest that health promotion strategies incorporating values, language and symbols that are meaningful to distinct subgroups may be more successful than disease-specific programs aimed at the general population.

Abstract
OBJECTIVE To describe the clinical features of serum sickness-like diseases (SSLD) in cefaclor-treated patients. DESIGN Analysis of a case series spontaneously reported to Lyons Pharmacovigilance Center. SETTING General and hospital practitioners and the French Network of Regional Pharmacovigilance Centers (FNRPC). PATIENTS All reported cases with a possible causative relationship between cefaclor treatment and SSLD. MAIN RESULTS Eight cases of SSLD following cefaclor treatment are described. The clinical features included cutaneous reactions, arthralgias, and moderate hyperthermia. In 50 percent of the patients, hospitalization was required because of incapacitating symptoms. The outcome was benign in all cases following discontinuation of the offending drug. All eight cases were reported in children under five years of age. Among 137 cefaclor-associated drug reactions collected by FNRPC, 27 cases of SSLD have been reported; 23 of these patients were younger than five years of age. A literature survey confirmed the higher reporting of SSLD in children with cefaclor compared with other antibiotics and suggested an incidence of 0.024-0.2 percent of SSLD per drug course of cefaclor. CONCLUSIONS The case reports and epidemiologic studies confirmed the presumed role of age (patients under five years of age) in cefaclor-induced SSLD and the benign outcome despite severe clinical presentations in some reports.

Abstract
We report a case of persistent infection with human parvovirus B19 (PVB19), manifesting clinically as recurrent agranulocytosis and in bone marrow biopsy as recurrent pure granulocytic aplasia. Persistence of parvovirus infection was documented by the presence of PVB19 DNA and anti-PVB19-IgM antibodies in the serum for a period of 19 months. Granulocytic aplasia occurred only when anti-PVB19-IgG antibodies were not detectable in the serum and granulopoiesis showed immediate recovery with high dose intravenous immunoglobulin treatment. This case report suggests that the erythroid precursor cell may not be the only target cell of PVB19 infection. We suggest testing for active parvovirus infection in cases of aplasia of any lineage of the haematopoietic system.

Abstract
Surveillance has become an alternative treatment modality for stage I non-seminomatous germ cell tumours with reported relapse rates of up to 30% in retrospective studies. Results obtained in our retrospective study showed vascular invasion in primary tumours to be the risk factor with the highest negative predictive value. Since January 1985 patients with stage I non-seminomatous germ cell tumours have been stratified by the presence or absence of vascular invasion in the primary tumour: those without vascular invasion (n = 26; group A) were subjected to a rigorous surveillance programme, while those with vascular invasion (n = 22; group B) were given 2 chemotherapy courses of bleomycin, etoposide and platinum in the hope of preventing progression. Relapse rates were 3.8% and 9% in groups A and B, respectively. The pooled relapse rate for both groups A and B (n = 48) was 6.2% (3/48). After a mean follow-up time of 36 months 95.8% (46/48) of the patients were without evidence of disease.

Abstract
UNLABELLED From 1985 to 1990 the sera of 372 newly imprisoned intravenous drug users (IDU) were tested for HIV-1 antibodies. The seroprevalence was 18%, males 16% and females 31%. HIV-1 seroprevalence in Austrian IDU has not increased since 1986. All sera tested for HTLV-I-antibodies were negative. The majority of the HIV-1 seropositive drug users had been infected before 1985. The reported frequency of needle sharing has decreased since 1986. Of 151 IDU tested for HCV antibodies 75% were positive for anti-HCV, 68% were positive for hepatitis B markers, 59% were positive for both HBV and HCV markers, and 13% were positive for HIV-1 antibodies. IN CONCLUSION in Austrian IDU HCV seems to be the most frequent parenterally transmitted virus; HIV-1 seroprevalence has not increased since 1986; HLTV-I infection has not yet begun.

Abstract
Fifteen patients with advanced urothelial cancer were treated with carboplatin 300 mg/m2, methotrexate 30 mg/m2, and vinblastin 3 mg/m2 on day 1 and the same dosage of methotrexate and vinblastin on days 15 and 22. Six patients were pretreated with radiotherapy and or chemotherapy; 7 patients had impaired renal function due to obstructive uropathy. Eight patients achieved a partial remission; 4 patients achieved a minor remission or stabilization of progressive disease. Mean duration of response was 8+ month (2+ to 12+ month). Subjective tolerance of the treatment was excellent but there was considerable bone marrow toxicity in the pretreated patients. The data show that Carbo-MV (carboplatin, methotrexate, and vinblastin) is effective and subjectively well tolerated in advanced urothelial carcinoma.
