Abstract
UNLABELLED PROBLEM DEFINITION: Increasing specialization can be observed in the various medical fields and as a consequence there is little professional exchange between ear nose and throat (ENT) specialists and general practitioners. At the same time there has been significant technological development in telemedicine over the last 5 years; however, this potential is not being sufficiently exploited. The objective of this project is to implement a practicable solution for teleconsulation between ENT specialists and general practitioners. MATERIALS AND METHODS The connection is based on a secure broadband internet connection, the corresponding server structure and a video endoscopic system. In the period from 01 January 2011 to 30 June 2012 (18 months) a total of 102 patients were included in the study in which 4 general practitioners and 5 ENT specialists participated. The protocol comprised the following parameters: indications and typical questions, number of patients presenting to the ENT specialist due to the available teleconsultation service (CBO), number of patients referred to the ENT specialist after teleconsultation (CIO), assessment of the quality of the additional expert opinion (LOQ GP), assessment of the accuracy of the specialist physician tele-diagnosis (TDS-FA) and assessment of the impact of the expert physician diagnosis on the general medical treatment (COS). RESULTS Teleconsultation was most frequently used for diagnostics on tonsils (37% of the presented cases), the external auditory canal (32%) and the inner nose (15%). Of the patients analyzed were 53.9% presented to the ENT specialist only because the teleconsultation service provided an effortless opportunity and after teleconsultation 40.1% of the patients were referred to the ENT specialist. General practitioners assessed the benefit from the specialist opinion with 64 points. Diagnostic certainty of the specialist opinion, i.e. the validity scale of the diagnosis made, was on average 2.0. In approximately 35.3% of the cases (36 out of 102 patients) participating general practitioners documented a considerable impact of teleconsultation on the diagnosis and/or therapy. CONCLUSIONS Teleconsultation between general practitioners and ENT specialists can provide an advantage in treatment quality and patient comfort. According to the experience gained there is a very low risk of diminishing the professional competency of ENT medicine and the involvement of the expert group in the early project stage allows a greater leeway in project implementation. This could also have an impact on future medical performance specifications. According to the ENT experts involved in the project further applications of teleconsultation are very conceivable.

Abstract
Imatinib has pronounced but brief antileukemic activity in advanced Philadelphia chromosome–positive acute lymphoblastic leukemia (Ph+ALL). We assessed the prognostic impact of pretreatment disease features and the early bone marrow (BM) response in 68 consecutive patients with Ph+ALL receiving imatinib salvage therapy. A complete hematologic or marrow response was achieved by 92% of patients with BM blasts below 5% on day 14, whereas 62.5% of patients with more than 5% BM blasts on day 14 were nonresponders. Similarly, time to progression (TTP) was superior in patients with a good day 14 response (5.2 versus 0.9 months; P < .0001). Prior complete remission of less than 6 months, white blood cell count of more than 10 × 109/L, circulating peripheral blood blasts at diagnosis, additional Philadelphia chromosomes, or at least 2 Bcr-Abl fusion signals were associated with significantly inferior remission rate and response duration. In patients without poor prognostic features, single-agent imatinib may be appropriate before transplant salvage therapy. Conversely, patients with clinically or cytogenetically defined poor-risk features are candidates for trials of upfront imatinib in combination with other agents.

Abstract
The BCR-ABL fusion, the molecular equivalent of the Philadelphia translocation, gains importance for treatment stratification in adult acute lymphoblastic leukemia (ALL). In this prospective study, samples from 478 patients with CD10(+) B-cell precursor ALL (c-ALL and pre-B ALL) underwent BCR-ABL reverse transcription-polymerase chain reaction (RT-PCR) analysis with double testing of positive samples. Patients were stratified according to the PCR result and treated in 2 German Multicenter Trials of Adult ALL. The outcome was followed and the prognostic impact of BCR-ABL was compared to clinical risk features. Of the 478 samples, 432 had an evaluable BCR-ABL result. Thirty-seven percent of the c-ALL and pre-B ALL patients were BCR-ABL(+) (p190, 77%; p210, 20%; simultaneous p190/p210, 3%). BCR-ABL positivity was associated with the high-risk features of older age (45 years versus 30 years median age; P =.0001) and higher white blood cell counts (23 500/microL versus 11 550/microL; P =.0001). Univariate and multivariate analyses revealed BCR-ABL as the leading factor for a poor prognosis (P =.0001) in comparison to clinical risk criteria. Irrespective of the breakpoint, presence of any BCR-ABL transcript predicted a lower chance of initial treatment response (68.4% versus 84.6%; P =.001) and a lower probability of disease-free survival at 3 years (0.13 versus 0.47; P =.0001). This bad outcome was not influenced by postinduction high-dose treatment stratifications. The results show a high prevalence of BCR-ABL fusion transcripts with predominance of p190. BCR-ABL RT-PCR is confirmed as a sensitive, rapid method to diagnose t(9;22), and p190 and p210 are unequivocally demonstrated as the most important predictors of poor long-term survival despite intensified chemotherapy.

Abstract
In patients with adult ALL, substantial progress has been made in the past 20 years. At present a cure rate of 30-40% can be achieved and varies in defined subgroups between 10-51%. ALL does not represent an uniform disease but is formed by biologic subentities, which differ in their natural history, clinical presentation and prognosis. A comprehensive diagnostic examination, including morphology, cytochemistry, immunology, cytogenetic and molecular genetic analysis is a precondition for prognostic assessment and therapeutic stratification. The basic principle of ALL treatment is a combination chemotherapy with sequential administration of induction, consolidation and maintenance therapy. Bone marrow transplantation has become an important part of the treatment strategy and is performed in patients with high risk. In the subgroup of T-ALL a significant progress has been made in the last years with survival rates of 40-50%. In B-ALL the results have been greatly improved to 48-51% by introduction of a specific treatment strategy. However, the results (about 30%) stagnate for the total group of B-lineage-ALL (common ALL, pre-B-ALL, pro-B-ALL). Patients with B-lineage-ALL can be subdivided in a high and low risk group according to the presence of risk factors (age, white blood cell count, time to achieve a complete remission, pro-B-ALL and the translocations t[4;11], t[9;22]). The outcome of the subgroup of adult pro-B-ALL has been substantially improved (50%). An increase of treatment results (20%) appears in outlines for patients above 50 years. The Ph/bcr-abl positive ALL has in spite of improved complete remission rates (60-70%) consistently unfavourable survival rates (10%).

Abstract
This prospective multicenter study examined whether simultaneous administration of granulocyte colony-stimulating factor (G-CSF; Filgrastim) and induction chemotherapy for adult acute lymphoblastic leukemia (ALL) could prevent treatment-related neutropenia, infections, and resulting treatment delays. Seventy-six patients were randomly assigned to receive either G-CSF (n = 37) or no growth factor (n = 39) in conjunction with a uniform chemotherapy consisting of cyclophosphamide, cytarabine, mercaptopurine, intrathecal methotrexate, and cranial irradiation. The median duration of neutropenia (absolute neutrophil count < 1 x 10(9)/L) during chemotherapy was 8 days in patients receiving C-CSF, compared with 12.5 days in the control group (P < .002). A similar reduction from 11.5 to 7 days was observed in patients with T-ALL receiving additional mediastinal irradiation (P = .13). Infections occurred in 43% and 56% of patients in the G-CSF and control arm, respectively (P = .25); the incidence of nonviral infections was reduced by 50%, from 32 episodes in the control arm to 16 episodes in the G-CSF arm. Prolonged interruptions of chemotherapy administration were less frequent, with delays of 2 weeks or more occurring in only 24% of patients receiving G-CSF as opposed to 46% in the control arm (P = .01). Accordingly, chemotherapy was completed significantly earlier with the use of G-CSF (39 v 44 days, P = .008). With a median follow-up of 20 months, the probability of disease-free survival was 0.45 in the G-CSF group and 0.43 in the control group (P = .34). In conclusion, adult ALL patients appear to benefit by the simultaneous administration of G-CSF with induction chemotherapy because of a significant reduction in the duration of neutropenia, a trend to fewer infections, and a more rapid completion of chemotherapy.

Abstract
A sprightly 79-year-old woman was treated for high blood pressure with indapamide (2.5 mg/day) and the angiotensin converting enzyme (ACE) inhibitor lisinopril (5 mg/day). About 12 months after starting treatment a blood count carried out because of a syncopal attack revealed pancytopenia (haemoglobin 3.3 g/dl, erythrocytes 1.0 x 10(6)/microliters, leucocytes 1100/microliters, platelets 8000/microliters). Until then the blood count had been unremarkable. The bone marrow showed severe hypoplasia of all three cell lines with reactive plasmocytosis. Malignant cells were not present. The patient received a total of nine units of erythrocytes and seven units of platelets. Her care included reverse barrier nursing and antibiotic treatment. She was also given high dose steroid therapy (methylprednisone up to 150 mg/day) and granulocyte colony stimulating factor (filgrastim 300 micrograms/day subcutaneously for 25 days), and after a latent period of several weeks juvenile myeloid precursors reappeared in the blood. Before discharge from hospital the results rose to subnormal levels without further transfusions (haemoglobin 8.5/dl, erythrocytes 3.1 x 10(6)/microliters, leucocytes 3900/microliters, platelets 21.000/microliters). In the bone marrow, all three cell lines were beginning to recover. The final diagnosis was incompletely reversible pancytopenia resulting from secondary aplastic anaemia during ACE inhibitor therapy.

Abstract
A 43-year-old homosexual man was hospitalized in April 1988 because of acute epigastric pain. It was known that he had had a HIV infection for a year, and in April 1988 it was defined as stage Walter Reed I. Acute, exudative, nonspecific pancreatitis was diagnosed. Three weeks later cerebral symptoms (disturbances of consciousness), hypoacusis, and impaired vision developed. The ocular fundus displayed areas of edema and whitish clouding in the retina, first in the left eye and later also in the right. These were initially assumed to be anemic infarctions until the differential diagnosis of acute retinal necrosis with possible herpesvirus infection was made. On the basis of ophthalmoscopic findings cytomegalovirus retinitis appeared improbable. Serologic examinations showed increased levels of IgG antibody titers of cytomegalovirus and herpes simplex virus (both 1:20,000). Therapy with intravenous infusions of Acyclovir was instituted (1500 mg/d). After a few days the patient regained consciousness as well as his hearing and vision. There was complete resolution of the retinal exudates. This excellent therapeutic result of Acyclovir therapy confirmed the diagnosis of acute retinal necrosis syndrome, identified the cerebral symptoms as herpes encephalitis, and explained the entire disease process as the first opportunistic infection in HIV infection, i.e., by that time the patient had developed stage Walter Reed 6 (AIDS). Problems of differential diagnosis and the therapeutic schedule with Acyclovir are discussed.

Abstract
Excess red blood cells (RBC) in patients with polycythemia vera (PV) are usually removed by repeated phlebotomy. In order to improve the efficacy of this treatment, we used isovolemic large-volume erythrocytapheresis (EA) by a cell separator. A retrospective analysis of our experience with 69 PV patients (206 EA procedures) is reported. EA induced a rapid, well-tolerated, and long-lasting reduction of Hct, Hb, and RBC counts, as well as an immediate disappearance or reduction of clinical symptoms of PV, while tissue oxygen tension - as measured in 8 patients - increased. Hct was reduced by EA from 56.8% +/- 5.6% to 41.9% +/- 6.6%, Hb from 17.5 +/- 2.3 to 12.7 +/- 2.4 g%, RBC counts from 7.4 +/- 0.9 to 5.4 +/- 0.9 x 10(6)/mm3. The mean volume of the apherisate was 1410 +/- 418 ml, (mean Hct 79.7% +/- 9.3%), and the actual RBC volume removed 1113 +/- 367 ml. The isovolemic procedure was well tolerated and the acceptance by patients seemed to be better than with repeated phlebotomy. In 21 patients whose Hct values (Hct before and after EA 58% +/- 5.7% and 41.5% +/- 4.9%) were regularly followed after EA the mean period with Hct less than 50% after a single EA procedure was 6.1 +/- 4.1 months (median, 6); in 14 out of these 21 patients a Hct of less than 43% after EA was reached and their mean period with Hct less than 50% after EA was 7.6 +/- 4.0 months (median, 7.5). For three patients this period was 11, 13, and 15 months, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Glucocorticoid receptors (GR) have been suggested to have prognostic significance in patients with CLL treated with chemotherapy containing glucocorticoid. In this study, the GR levels in 65 patients with advanced CLL and immunocytoma (clinical stages III and IV according to Rai) were determined by means of a whole cell assay. The median GR-level was 1,920 bs/c with a range from 0 to 9591. The patients were subsequently treated according to a prospective, randomized trial with either a combination of chlorambucil and prednisolone, or with prednimustine. No significant difference in receptor levels was found between responders (median = 1940 bs/c; n = 47) and nonresponders (median = 1950 bs/c; n = 14). To assess the influence of receptor content on prognosis we have analyzed the relationship between GR content and survival time and duration of response. There was no significant difference in duration of response and in survival between those patients with high (greater than 1920 bs/c) and those with low GR levels (less than 1920 bs/c) (log-rank test). Our data suggest that determination of GR provides no reliable indicator for clinical response to regimens with glucocorticoid as a component in patients with CLL and immunocytoma.

Abstract
In the risk-adapted multicenter trial (02/84) for adult ALL the effectiveness of a consolidation therapy consisting of VM26 and Ara-C for high-risk patients was tested. Out of a total of 442 patients in the study, 79.2% achieved a complete remission. For the 182 high-risk patients the median remission duration is 17 months and the probability of being in continuous complete remission (CCR) is 34%. Improved results were found for elderly ALL patients between 35 and 65 years of age, whose median remission duration and CCR rate are 19 months and 40% respectively, compared to 15 months and 26% in the former study 01/81. The consolidation therapy has apparently also benefited patients with the immunological subtype c-ALL, for whom the CCR rate at 3 years is 53% in comparison to the previous value of 34%.

Abstract
Both mitoxantrone and etoposide have been shown to be active in monotherapy trials of relapsed and refractory acute myelogenous leukemia (AML). This phase II study was undertaken to assess the antitumor activity and toxicity of the combination in refractory and poor-risk AML. The regimen consisted of mitoxantrone, 10 mg/m2/d intravenously (IV), and etoposide, 100 mg/m2/d as short infusion, both on days 1 to 5. Sixty-one patients are evaluable for response and toxicity. Twenty-one were primarily refractory to conventional courses of cytarabine, daunorubicin, and thioguanine; 20 patients had poor-risk first relapse (relapse within 6 months of first complete remission [CR] or relapse under continuous maintenance therapy); 11 had second or subsequent relapses; and nine developed secondary AML after myelodysplastic phase or myelofibrosis. Twenty-six patients (42.6%) attained a CR and seven (11.5%) a partial remission (PR). The median duration of continuous CR was 4.7 months, with a range of 21 days to 14 months, excluding four patients who underwent autologous bone marrow transplantation. Severe myelosuppression was observed in all patients, with a median time to CR of 49 days. Nonhematologic toxicity included stomatitis (mainly grade 1 and 2) in 41 patients, nausea (mainly grade 1 and 2) in 44, infections (mainly grade 3) in 33, and fever of unidentified origin in 11. Other than transient, mild cardiac failure in nine patients, in some of them combined with grade 1 to 2 tachyarrhythmia, no other drug-related cardiac events were observed. Two cases of early death within the first 6 weeks of treatment were registered. Thus, the combination of mitoxantrone and etoposide is a highly active and well-tolerated regimen for refractory and poor-risk AML.

Abstract
We have investigated the efficacy of mitoxantrone in combination with etoposide in patients with refractory acute myelogenous leukemia. The regimen consisted of 10 mg/m2/day of mitoxantrone given iv on Days 1-5; and 100 mg/m2/day of etoposide as short infusion, initially on Days 1-3 and extended to Days 4 and 5 as appropriate. Of the 26 patients treated with this combination, nine (34.6%) have achieved complete remission and two have achieved partial remission. The median duration of continuous complete remission was 85 days (range, 21-183+). Toxicity was mild and only one case of early death was observed. This combination seems to be an active regimen in refractory acute myelogenous leukemia, and its incorporation in front-line therapy seems warranted.

Abstract
Phase I/II-studies suggested that mitoxantrone is effective in the treatment of acute leukemia. In this study we have investigated its efficacy in combination with VP-16 in patients with refractory acute myelogenous leukemia. The regimen consists of: mitoxantrone 10 mg/m2/day i.v. from days 1 to 5, VP-16 100 mg/m2/day as short infusion from days 1 to 3. A dosis escalation of VP-16 was attempted. As of August 1985, 27 patients have been enrolled in the study and 21 patients are now evaluable. Of these 21 patients, 6 (28.6%) have achieved complete remission including 3 with primary refractory disease, 2 with early relapse (less than 6 months after CR), and 1 with relapse under maintenance therapy. Two other patients have attained a partial remission. Toxicity was mild and, except one case of early death, no life threatening complications were observed. This combination seems to be an active regimen in refractory acute myelogenous leukemia and its incorporation in front line therapy seems warranted.
