Second-line treatment of limb-threatening diabetic foot infections with intravenous fosfomycin.

Diabetic foot infections (DFI) expanding to bones and joints are associated with a poor prognosis of limb salvage. The bactericidal epoxide fosfomycin accumulates in inflamed soft and bone tissue, and may represent a potential treatment option for targeting severe DFI. Fifty-two patients (35 men, 17 women, mean age 62.9 +/- SD 9.2 years) with limb-threatening DFI (that is, Wagner grade 3 and higher) were enrolled in a multi-center compassionate use program of fosfomycin. Twenty-two patients (42.4%) had unsuccessfully been pretreated with other antimicrobials. Besides standard treatment (topical wound care and surgical debridement), eligible subjects received a combination of 8 to 24 g fosfomycin daily, and a conventional antibiotic agent, usually a beta-lactam compound. Treatment duration averaged 14.4 +/- 8.3 days. Limb-sparing surgery was possible in 48 patients (92.3%, 95% confidence interval 81.5-97.9%). Only four participants faced mild drug-related side effects (nausea, rash). Logistic regression analysis showed a trend towards better results with prolonged treatment, whereas a dose increase above 12 g daily did not affect outcomes. In DFI being resistant to conventional antibiotic agents, intravenous fosfomycin offers an effective treatment choice that may increase the likelihood of limb preservation. The present data warrant a larger comparative trial to stabilize effect estimates.

The impact of resection margins in the treatment of primary sarcomas of the breast. A clinicopathological study of 8 cases with review of literature.

We reviewed the clinical and pathological features of eight patients (seven females, one male), who underwent surgery for sarcomas of the breast, to evaluate the effect of the margins of resection and histological tumor type on survival. Patients with carcinosarcoma, cystosarcoma phyllodes or dermatofibrosarcoma protuberans were excluded. Tumor size ranged between 4.5 and 26 cm (median 12.8 cm); there were three grade 3, four grade 2 and one grade 1 lesions. Of the five patients treated by radical resection margins, two with large grade 3 sarcomas died of distant metastasis 3 and 10 months later. One patient out of the five radical resected patients developed a local recurrence 96 months later. The recurrence was resected radically, radiotherapy was administered, and the patient is still alive at 168 months. The remaining four radical resected patients are free of disease until now. One of three patients, treated by wide or marginal resection, received adjuvant radiotherapy. This patient developed local recurrence and solitary distant metastasis at 26 and 49 months, respectively, and died of multiple distant metastasis at 54 months. Regional axillary lymph node metastasis was not observed in five patients in whom lymph node dissection was performed, with a median of 14.2 dissected lymph nodes. Two of eight patients received preoperative chemo- or radiotherapy because of large tumor size; five of eight received postoperative radiotherapy. Local tumor control was achieved in six of eight patients. The median follow-up time was 53.9 months (3-168 months), of all survivors median 72.2 months. Recurrence and disease-free survival rates were analysed according to histologic grade, tumor size, stage, surgical and adjuvant treatment.

The best TcpO(2) parameters to predict the efficacy of spinal cord stimulation to improve limb salvage in patients with inoperable critical leg ischemia.

AIM: Spinal cord stimulation (SCS) is available as an alternative therapy for patients suffering from inoperable critical limb ischemia (CLI). Selection of patients is essential to achieve the best treatment effect. For this purpose transcutaneous oxygen (TcpO(2)) measurements have frequently been applied. So far, it is unclear which TcpO(2) parameters serve this purpose best. METHODS: Studies in which inoperable CLI patients were treated with conservative treatment with or without SCS, and in whom various TcpO(2) measurements were performed before and during treatment were pooled to investigate which TcpO(2) parameter(s) were best to detect patients who benefit most from SCS treatment as to limb salvage. RESULTS: TcpO(2) in the supine position increased significantly (p<0.001) in patients after a short period of SCS treatment (from 9 to 22 mmHg), but not in those treated conservatively (from 7 to 7 mmHg). Baseline supine TcpO(2) (using a cut-off value of 10 mmHg), the baseline sitting-supine TcpO(2) difference (cut-off value: 17 mmHg), and the difference in TcpO(2) before and after test stimulation (cut-off value: 4 mmHg) were related to a significantly increased limb salvage. SCS patients with a sitting-supine TcpO(2) difference of >17 mmHg had a 1-year limb salvage of 83% vs 68% in the whole SCS-treated group irrespective of TcpO(2) selection. CONCLUSION: The TcpO(2) parameters mentioned above are capable of detecting the effect of SCS treatment. Selection using (a combination of) TcpO(2) measurements substantially improves limb salvage of patients treated with SCS for inoperable CLI.

[Local vascular complications after iatrogenic femoral artery puncture]. / Lokale Gefässkomplikationen nach iatrogener Femoralarterienpunktion.

Over a period of 5 years 81 vascular complications after 15,460 catheterizations of the femoral artery for diagnostic (n = 11,883) or therapeutic (n = 3577) procedures were registered. The following complications were observed in declining frequency: 1. False aneurysm (n = 65), 2. arterial occlusion (dissection, embolia, thrombosis) (n = 8), 3. vascular lesion causing profuse bleeding (n = 7), 4. AV-fistula (n = 1). The total complication rate was 0.52%. The complication rate was significantly higher in therapeutical procedures (1,03%) than in diagnostic investigations (0.37%). Pseudoaneurysms were complicated by thrombosis of the femoral vein (n = 3), lymphatic fistula (n = 3) and deep wound infection (n = 9); secondary complication rate 18.5%. Risk factors for local vascular complications are old age, female gender, high grade arteriosclerosis at the puncture site, overweight, manifest arterial hypertension and medication with cumarin, acetylsalicylic acid or heparin. Further complicating factors are connected with technical risks such as duration of the procedure. French size of the catheter, the catheter sheath and multiple punctures. Vascular repair was performed by simple angiography in most cases, but in 14.8% more extensive surgical procedures were required. In patients with signs of occlusive vascular disease the external iliac artery was replaced by a PTFE-vascular access graft in 4 cases and an arterioplasty of the deep femoral artery was performed in 2 patients. 36% of the operations were undertaken as emergencies. Reintervention was necessary for a postoperative bleeding complication in 1 case (surgical complication rate 1.2%). A female patient suffering from aortic valve stenosis died during emergency operation due to massive retroperitoneal hemorrhage after cardiac catheterization (mortality rate 1.2%). Over a median follow-up period of 37 months no late complications of the intervention were recorded, nor recurrences of peripheral arterial occlusive disease.

Aplasia of the vena cava inferior as a cause for recurring thrombosis of the lower extremities and pelvic veins.

Congenital anomalies of the caval vein are often associated with other abnormalities such as heart defects, situs inversus or a polysplenia-asplenia-syndrome. An isolated, congenital malformation like aplasia of the inferior vena cava is a rare finding. A review of the embryology and abnormalities, diagnostics, clinical signs and treatment is given together with the histories of two patients having thrombosis of the lower extremities and pelvic veins, caused by aplasia of the inferior vena cava. After thrombotic complications caused by vena cava aplasia there is high risk of recurrence. Those patients should be anticoagulated for lifetime.

Endovascular stentgraft infection--a life-threatening complication.

The implantation of covered stents or stentgrafts has increased greatly in the last few years for the endovascular reconstruction of arterial aneurysms. We report of three patients experiencing severe septic complications after stentgraft implantation. Endovascular stentgraft infection is a serious complication with high morbidity and mortality. General antibiotic prophylaxis seems to be indicated when implanting stentgrafts.

[Transposition of the subclavian artery with endovascular stent graft implantation for therapy of acute type B aortic dissection]. / Die Transposition der Arteria subclavia mit endovaskulärer Stentgraft-Implantation zur Therapie der akuten Aortendissektion Typ B.

We report about a patient with a thoracic aneurysm caused by an acute type-B dissection. Due to the concomitant affections the risk of surgery was distinctly increased, the reconstruction was performed endo vascular by stentgraft implantation (Talent, World Medical Systems, Sunrise FL) after transposition of the left subclavian artery to create a sufficient neck for the proximal stent placement. Endoluminal treatment seems to be a promising, less invasive alternative method in the treatment of acute aortic dissections.

[Primary bacterial infection of an artery]. / Die primär bakteriell infizierte Arterie.

INTRODUCTION: Primary bacterial infection of an artery is difficult to diagnose, especially at the beginning of the illness. Most of the patients come for emergency treatment in the phase of rupture. METHODS: The course of illness in four patients serves as background for discussion of the problems of diagnosis and therapy. RESULTS: Bacterial infection of arteries shows a high rate of complications and, for the aorta, high mortality. CONCLUSION: If fever of uncertain origin is combined with pain of the stomach or of the back, or with a painful reddish swelling on a limb, this rare disease should be considered in the differential diagnosis.

Results and complications in endovascular treatment of abdominal aortic aneurysms--a single center experience.

Between September 1996 and February 2000 five female and 62 male patients with an abdominal aortic aneurysm, requiring therapy, underwent endoluminal treatment. Their age ranged from 51 to 81 years (mean 72 years). Preoperative evaluation was done with spiral computed tomography (CT) and angiography. All procedures were performed under general anesthesia in a radiologically adapted operating room. Postoperative complications occurred in 28.4%. The total conversion rate was 13.4%, the 30-day lethality rate was 1.4%. During the mean follow-up of 15.1 months 19 secondary interventions were necessary in 13 patients. The results presented in this study do not justify the wide use of this method and indicate a stricter form of patient selection.

[Isolated pelvic vein thrombosis in a young marathon runner]. / Isolierte Beckenvenenthrombose bei einer jungen Marathonläuferin.

The case of a 20-year old female patient who developed an isolated thrombosis of the pelvic vein after a marathon run, is presented. After surgical treatment and anticoagulation for one year, complete restitution was seen. The possible relation between marathon running and venous thrombosis without other risk factors is discussed.

[Development of acne following pregnancy (postgestational acne)]. / Auftreten einer Akne nach Schwangerschaft (Postgestative Akne).

A woman is reported, in whom acne appeared after pregnancy. There are similar conditions in postcontraceptive acne and in acne after pregnancy. For acne after pregnancy the term "postgestative acne" is proposed.

[Primary bacterial aortitis]. / Die primär bakterielle Aortitis.

Primary bacterial aortitis represents a rare disease with a high lethality. From June 1997 to April 1999 5 patients with an abdominal aortic infection were treated by resection of the infected aorta and in-situ reconstruction or by extra-anatomic bypass. There was no treatment in one case because of the infaust prognosis. 3 patients survived, one with a paraparesis as a result of spinal ischemia. On the basis of our patients the pathogenesis, clinical symptoms with diagnosis and the therapeutic options are discussed.

[Treatment of acute myocardial infarction in Switzerland: is emergency PTCA more costly than thrombolysis?]. / Behandlungskosten des akuten Myokardinfarkts in der Schweiz: Ist die Akut-PTCA teurer als die Thrombolyse?

Confirming earlier studies with a lower number of patients, the Gusto IIb Angioplasty Substudy has shown that in the treatment of acute myocardial infarction emergency PTCA is superior to thrombolysis in reducing the combined clinical endpoints of death, reinfarction and cerebrovascular infarction. The aim of this study was to assess whether, in the Swiss study population of Gusto IIb, emergency PTCA was associated with higher procedural costs than thrombolysis over a median follow-up of 16 months. Therefore, we compared the costs of the initial and the follow-up hospitalisations. There were no differences in clinical characteristics in the Swiss subpopulation compared to the total study population. In a total of 46 patients, PTCA was performed in 22 and thrombolysis with rtPA in 24. During follow-up, 4 patients died, one in the PTCA group and 3 in the thrombolysis group (p = ns). The median total costs of the initial hospitalisation were somewhat higher in the PTCA group than in the group with thrombolysis. During follow-up only 38% of the patients in the PTCA group had to be rehospitalised, compared to 50% in the thrombolysis group. Median total costs within 16 months, therefore, were similar in the two therapeutic groups, but mean total costs per patient were somewhat lower for the PTCA versus the thrombolysis group (p = ns). Based on this comparison of Swiss procedural costs, emergency PTCA should not, in hospitals with the necessary infrastructure, be withheld in the treatment of acute myocardial infarction on the grounds of initially higher procedural costs, especially as the invasive strategy is associated with a more favourable long-term outcome.

[Posttraumatic aneurysm of the brachiocephalic trunk: a rare injury]. / Aneurysma des Truncus brachiocephalicus nach stumpfem Thoraxtrauma. Eine seltene Verletzung.

We report on a posttraumatic aneurysm of the brachiocephalic trunk, something which is rather rare. The injury was caused by blunt chest trauma following a car accident. Computed tomography could not find the brachiocephalic lesion. In patients with fractures of the upper ribs after blunt chest trauma, angiography should be done to exclude severe injuries of the aorta and brachiocephalic vessels.

Spinal cord stimulation in the treatment of non-reconstructable stable critical leg ischaemia: results of the European Peripheral Vascular Disease Outcome Study (SCS-EPOS).

OBJECTIVE: To determine the effect of spinal cord stimulation (SCS) on limb survival in patients with non-reconstructable critical leg ischaemia, and the value of patient selection on the basis of transcutaneous oxygen pressure (TcpO2) measurements and trial screening. DESIGN: A prospective, controlled, European multicentre study. METHODS: Non-reconstructable patients with stable critical leg ischaemia were divided into three groups. The SCS-Match group comprised patients with a baseline forefoot TcpO2 of < 30 mmHg and both sufficient pain relief and sufficient paraesthesia coverage (> 75%) after a test stimulation period of at least 72 h. If baseline TcpO2 was < 10 mmHg, the TcpO2 should have exceeded 20 mmHg after test stimulation. The SCS-Match group was compared with patients not meeting these criteria, who were treated either with SCS (SCS-No-Match) or without SCS (No-SCS). RESULTS: At baseline, the mean (+/- SD) supine TcpO2 was 14.9 +/- 8.3 mmHg in the SCS-Match group (n = 41), 11.3 +/- 13.3 mmHg in the SCS-No-Match group (n = 32) and 15.3 +/- 17.1 mmHg in the No-SCS group (n = 39). In the SCS-Match group a significant improvement in pain relief (p < 0.005) and TcpO2 (p < 0.001) was seen. After 12 months, cumulative limb survival of patients treated with SCS was significantly better than that of patients not treated with SCS (p < 0.03), and limb survival in the SCS-Match group was significantly higher (p < 0.03) than that in the SCS-No-Match and No-SCS groups (78, 55 and 45%, respectively). CONCLUSION: SCS treatment of non-reconstructable critical leg ischaemia provides a significantly better limb survival rate compared with conservative treatment. Patient selection based on TcpO2 and the results of trial screening further increase the probability of limb survival after SCS therapy.

Endovascular treatment of proximal anastomotic aneurysms after aortic prosthetic reconstruction.

PURPOSE: To describe the efficacy and value of endovascular stent-grafts for the treatment of aortic anastomotic pseudoaneurysms. METHODS: Three patients with proximal aortic anastomotic pseudoaneurysms 8--15 years after prosthetic reconstruction were treated by transfemoral stent-graft implantation. In two patients the pseudoaneurysms were excluded by Talent prostheses [tube graft (n = 1), bifurcated graft (n = 1)]. In one patient an uniiliac Zenith stent-graft was implanted and an extra-anatomic crossover bypass for revascularization of the contralateral lower extremity was performed. RESULTS: All procedures were successful with primary exclusion of the pseudoaneurysms. During the follow-up (mean 16 months) one endoleak occurred due to migration of the tube stent-graft. The endoleak was sealed successfully by implanting an additional bifurcated stent-graft. CONCLUSION: Stent-graft exclusion of aortic pseudoaneurysms offers a minimally invasive and safe alternative to open surgical reconstruction.

Endovascular stent-graft repair of acute thoracic aortic dissection--early clinical experiences.

BACKGROUND: Standard treatment of acute thoracic aortic dissection type B is the medical therapy used for most patients, according to Stanford. Surgical therapy involves a high mortality rate and is reserved for patients with complicated dissections. We report from four patients with acute thoracic aortic dissection, treated endoluminally by stent-graft implantation. METHODS: Four patients with complicated acute thoracic aortic dissections type B were treated endoluminally by transfemoral stent-graft implantation. Preoperative evaluation was performed with spiral-computed tomography and calibrated aortography. The Talent stent-graft system (Metronic) was used in all patients. RESULTS: The primary entry tear could be sealed successfully and complete thrombosis of the false thoracic aortic lumen was obtained in all cases. In one patient, transposition of the left subclavian artery was performed, in two patients the stent-grafts had to be placed across the origin of the left subclavian artery. No severe intra- or postoperative complications occurred. CONCLUSION: Endoluminal treatment of acute thoracic aortic dissection seems to be a less invasive and effective therapy. Long-term results for this method are necessary.

Biochemical and hormonal parameters in patients with multiple trauma.

We measured amount, course and duration of different parameters in order to assess metabolic-endocrine changes in patients with multiple trauma and the final outcome. Injures were initially quantified according to the Injury Severity Score. Serum levels of lactate, creatinine, bilirubin, somatomedin and thyroid hormons were measured in 51 patients (39 survivors, 12 deceased patients) for six days following the injury. In addition, neopterin levels were measured in 26 patients (19 survivors, 7 deceased patients). The patients were devided into two groups (survivors vs non-survivors). Global Index Scores and Septic Severity Scores were significantly different at the 1% and 5% level (p less than 0.05 to p less than 0.01). The same statistical differences were shown for lactate, somatomedin, neopterin and thyroid hormones.

[Arterial complications caused by using an axillary crutch]. / Arterielle Komplikation durch Verwendung einer Achselstützkrücke.

BACKGROUND: Of all upper extremity emboli, up to twenty percent arise from an arterial, not a cardiac source. METHOD: We report about a patient with recurrent embolism, caused by an axillary crutch-induced aneurysm of the axillary artery. RESULT: After revascularisation by embolectomy and axillo-brachial vein graft bypass, the patient was free of symptoms. CONCLUSION: Angiography and duplex scanning were necessary for the correct diagnosis.
