Prevalence and prognostic implication of restenosis or dilatation at the aortic coarctation repair site assessed by cardiovascular MRI in adult patients late after coarctation repair

Background

Cardiovascular magnetic resonance (CMR) is ideal for assessing patients with repaired aortic coarctation (CoA). Little is known on the relation between long-term complications of CoA repair as assessed by CMR and clinical outcome. We examined the prevalence of restenosis and dilatation at the repair site and the long-term outcome in patients with repaired CoA.

Methods and results

CMR imaging and clinical data for adult CoA patients (247 patients aged 33.0 ± 12.8 years, 60% male), were analyzed. The diameter of the aorta at the repair site was measured on CMR and its ratio to the aortic diameter at the diaphragm (repair site-diaphragm ratio, RDR) was calculated. Restenosis (RDR ≤ 70%) was present in 31% of patients (and significant in 9% [RDR < 50%]), and dilatation (RDR > 150%) in 13.0%. A discrete aneurysm at the repair site was observed in 9%. Restenosis was more likely after resection and end–end anastomosis, whereas dilatation after patch repair. Systemic hypertension was present in 69% of patients. Of the hypertensive patients, blood pressure (133 ± 20/73 ± 10 mm Hg) was well controlled in 93% with antihypertensive therapy. Mortality rate over a median length of 5.9 years was low (0.69% per year, 95% CI: 0.33–1.26), but significantly higher than age-matched healthy controls (standardised mortality ratio 2.86, CI 1.43–5.72, p < 0.001).

Conclusion

Restenosis or dilatation at the CoA repair site as assessed by CMR is not uncommon. Medium term survival remains good, however, albeit lower than in the general population. Life-long follow-up and optimal blood pressure control are likely to secure a good longer term outlook in these patients.     

HyperCVAD for VAD-resistant multiple myeloma

More effective and safer regimens are needed for patients who have advanced multiple myeloma resistant to or relapsing despite prior treatment with alkylating agents and VAD. We treated 58 such patients using the combination of twice daily cyclophosphamide (total dose 1.8 g/m²) and VAD (hyperCVAD). Treatment was given to outpatients followed by G-CSF at 5 μg/kg/d until granulocyte recovery. Twenty-three patients responded (40%), with a median duration of granulocyte depression to less than 500/μl of 4 days and a mortality rate of 2%. The median survival time for all patients was 15 months, and the median remission time of responding patients was 8 months. Patients who had low LDH, low B₂M, or primary resistant disease lived significantly longer than patients without these features. The combination of fractionated cyclophosphamide and VAD provided an effective and safe rescue treatment for many patients who had advanced myeloma resistant to standard therapies. © 1996 Wiley-Liss, Inc.     

European Myeloma Network recommendations on the evaluation and treatment of newly diagnosed patients with multiple myeloma

Multiple myeloma management has undergone profound changes in the past thanks to advances in our understanding of the disease biology and improvements in treatment and supportive care approaches. This article presents recommendations of the European Myeloma Network for newly diagnosed patients based on the GRADE system for level of evidence. All patients with symptomatic disease should undergo risk stratification to classify patients for International Staging System stage (level of evidence: 1A) and for cytogenetically defined high- versus standard-risk groups (2B). Novel-agent-based induction and up-front autologous stem cell transplantation in medically fit patients remains the standard of care (1A). Induction therapy should include a triple combination of bortezomib, with either adriamycin or thalidomide and dexamethasone (1A), or with cyclophosphamide and dexamethasone (2B). Currently, allogeneic stem cell transplantation may be considered for young patients with high-risk disease and preferably in the context of a clinical trial (2B). Thalidomide (1B) or lenalidomide (1A) maintenance increases progression-free survival and possibly overall survival (2B). Bortezomib-based regimens are a valuable consolidation option, especially for patients who failed excellent response after autologous stem cell transplantation (2A). Bortezomib-melphalan-prednisone or melphalan-prednisone-thalidomide are the standards of care for transplant-ineligible patients (1A). Melphalan-prednisone-lenalidomide with lenalidomide maintenance increases progression-free survival, but overall survival data are needed. New data from the phase III study (MM-020/IFM 07-01) of lenalidomide-low-dose dexamethasone reached its primary end point of a statistically significant improvement in progression-free survival as compared to melphalan-prednisone-thalidomide and provides further evidence for the efficacy of lenalidomide-low-dose dexamethasone in transplant-ineligible patients (2B).     

Versagung einer Apothekenbetriebserlaubnis wegen Vereinbarung einer Umsatzmiete für ein Medizinisches Versorgungszentrum

Abstrakt 1. Die Vereinbarung einer am Umsatz oder Gewinn einer Apotheke ausgerichteten Miete ist nach § 8 S. 2 ApoG unzul?ssig. Das Verbot der Umsatzmiete gilt insbesondere für die Anmietung von Apothekenbetriebsr?umen. 2. Aus dem Gesamtgefüge der Vereinbarungen kann sich ergeben, dass die Vertragsparteien die Miete am Umsatz oder Gewinn ausgerichtet haben und der Vermieter dadurch an den Ertr?gnissen der Apotheke teilhat. 3. Ein immens hoher Mietzins engt die wirtschaftliche Bewegungsfreiheit des Apothekers erheblich ein und macht ihn zumindest indirekt vom Vermieter abh?ngig. 4. Der Umstand, dass die Apothekenansiedlung im Kontext eines Medizinischen Versorgungszentrums geplant ist, ?ndert nichts an der uneingeschr?nkten Geltung des § 8 S. 2 ApoG.

Laparoscopy in the evaluation of women with unexplained ascites: an invaluable diagnostic tool

STUDY OBJECTIVE: To assess whether laparoscopy is a reliable technique for the investigation of women presenting with ascites and in whom the diagnosis remains obscure. DESIGN: Prospective nonrandomized clinical study (Canadian Task Force classification II-2). SETTING: University Departments of a tertiary referral center. PATIENTS: Women presenting in our institution with ascites in whom the diagnosis remained obscure after an extensive nonoperative diagnostic work-up. INTERVENTION: Undiagnosed cases were submitted to laparoscopy, and selective biopsy specimens were taken for histologic study. MEASUREMENTS AND MAIN RESULTS: Over a 3-year period, 73 patients were admitted to our institution with diffuse ascites. In 9 patients (12.3%), the diagnosis remained obscure, and these patients were further investigated with laparoscopy. Selective biopsy specimens obtained at laparoscopy clarified the specific cause of the ascites in all 9 patients. Peritoneal carcinomatosis was responsible in 5 patients (a metastatic gastrointestinal tumor in 1 patient, a malignant mesothelioma of the peritoneum in 1 patient, and a serous papillary carcinoma of the peritoneum and of the ovary in 2 and 1 patients, respectively). Three patients were found with miliary peritoneal tuberculosis, and the last patient had an unusual peritoneal reaction to methylene blue after laparoscopic adhesiolysis. CONCLUSION: Laparoscopy is a valuable means of assessing the peritoneal cavity in patients with unexplained ascites, where the primary cause remains unclear. The diagnosis can be accurately made with selective biopsy specimens, and appropriate treatment can be instituted without delay.     

Community-acquired <Emphasis Type="Italic">Stenotrophomonas maltophilia</Emphasis> infections: a systematic review

Stenotrophomonas maltophilia is a pathogen that causes infections mainly in immunocompromised patients. However, community-acquired S. maltophilia infections have been occasionally reported. The objective of this paper was to collect and evaluate the available published data referring to community-acquired S. maltophilia infections. We searched PubMed, the Cochrane Library, and Scopus for articles providing data for patients with community-acquired S. maltophilia infections. Eight case series and 23 case reports (involving 77 and 26 patients with community-acquired S. maltophilia infections, respectively) were regarded as eligible for inclusion in our review. Regarding the 77 patients with community-acquired S. maltophilia infections included in the identified case series, 45 had bacteremia, six ocular infections, five respiratory tract infections, four wound/soft tissue infections, two urinary tract infections, one conjunctivitis, one otitis, and one cellulitis; data were not reported for the remaining 12 patients. Comorbidity (such as malignancy, HIV infection, prior hospitalization) was common. Data included in the eight case series regarding the outcome of infection were limited. From the 26 patients with community-acquired S. maltophilia infections reported in the case reports, 22 were cured from the infection, whereas 4 of 26 patients died; one death was attributed to septic shock due to S. maltophilia. Several publications report patients with community-acquired S. maltophilia infections; the majority of them refer to patients with some kind of comorbidity. Physicians should be aware that S. maltophilia infections are not restricted to hospitalized patients.     

Biweekly gemcitabine and cisplatin in platinum-resistant/refractory, paclitaxel-pretreated, ovarian and peritoneal carcinoma

OBJECTIVES: Synergism between gemcitabine and cisplatin is supported by preclinical and clinical data. The present study explores the efficacy of a biweekly regimen in platinum-resistant/refractory, paclitaxel-pretreated ovarian and peritoneal cancer. METHODS: 50 paclitaxel-pretreated patients with platinum-resistant/refractory ovarian or peritoneal carcinoma who had previously received paclitaxel chemotherapy, were treated with six cycles of gemcitabine 1000 mg/m(2) followed by cisplatin 40 mg/m(2) on days 1 and 15, repeated every 4 weeks. RESULTS: The median platinum-free interval (PFI) was 4 months while the median number of previous treatment lines was 2. Chemotherapy was well tolerated. Objective responses were observed in 31.5% of evaluable patients (n=35). CA125 response was observed in 68% of patients with elevated CA125 (n=41). Median overall survival (OS) was 13.2 months (95% Confidence Interval, CI: 10.2-16.2) while progression-free survival (PFS) was 4.9 months (95%CI: 3.5-6.4). A PFI of less than 3 months was associated with lower objective response rates (15.8% versus 50%, p=0.03). CONCLUSIONS: Biweekly gemcitabine and cisplatin is feasible for patients with platinum-resistant ovarian or peritoneal cancer and is associated with a favorable toxicity profile. In a population with recent exposure to platinum, a PFI of less than 3 months was the major factor influencing response to chemotherapy.     

Potential risk factors for infection with Candida spp. in critically ill patients

The incidence, risk factors and prognostic factors for candidal infection were determined in a prospective study of 280 infected patients. Thirty-one (11%) patients were infected with Candida spp., sub-divided into 18 (58%) with C. albicans, and 13 (42%) with non-albicans spp. (six C. glabrata, three C. parapsilosis, and one each of C. krusei, C. tropicalis, C. guilliermondii and C. lusitaniae). Infection with Candida spp. was always associated with concurrent bacterial infection. By univariate logistic regression analysis, the degree of morbidity and the duration of mechanical ventilation were independent predictive factors for death, but infection with Candida spp., was not. Factors associated with Candida spp. infection were the degree of morbidity, intensive care unit length of stay, alterations of immune response, and the number of medical devices involved. By multivariate logistic regression analysis, the only independent risk factor for candidal infection was intensive care unit length of stay.
