Ultrasound-guided antegrade femoral access: comparison between the common femoral artery and the superficial femoral artery.

PURPOSE: The aim of this study was to compare ultrasound-guided access of the superficial femoral artery and the common femoral artery. MATERIAL AND METHODS: 100 patients were randomized to ultrasound-guided access either into the SFA or the CFA. The two groups were compared with respect to technical success, access time and complications. In addition, a subgroup analysis was performed to compare the complication rate using manual compression versus closure devices for haemostasis. RESULTS: In the SFA group 49/50 patients were successfully accessed in the assigned location, compared to 41/50 in the CFA group (p = 0.016). The median access time was significantly faster in the SFA group (3 min 25 s) compared to the CFA group (5 min 26 s) (p < 0.001). The most frequent complications in the SFA group were pseudoaneurysms (16.3%) whereas access site haematomas (14.6%) were the most common complication in the CFA group. However, when looking at subgroup with closure devices there was no difference between the SFA group compared to CFA group (p = 1.000). CONCLUSION: Accessing the SFA was more often successful and significantly faster than puncturing the CFA. The pseudoaneurysm rate was higher in the SFA group when using manual compression, but similar when using closure devices.

Extracorporeal shockwave therapy for Peyronie's disease does not correct penile deformity.

To evaluate whether extracorporeal shockwave therapy (ESWT) offers an effective treatment for the main complications of Peyronie's disease (PD), that is, penile deformity and angulation, painful erection and most importantly unsatisfied sexual intercourse. From September 1999 to January 2001, 52 patients with PD were treated with ESWT. Pain during erection was assessed with a visual analogue scale. Penile deviation was determined by photographs with a goniometer. Five treatment sessions were performed at weekly intervals. Each consisted of 3000 shockwaves with an emission frequency of 120 shockwaves/min and a mean intensity of 0.17 mJ/mm(2). A Storz Minilith SL 1 with integrated inline ultrasound probe was used. In all, 52 patients were evaluated 6 weeks after ESWT for early follow-up. Before ESWT intercourse was difficult or impossible for 40 men; 29 patients suffered mainly from penile deformity, 14 from painful erection and eight mainly from loss of distal rigidity. A total of 30 patients mentioned painful erection before treatment. In 28 patients (93%) pain reduction was achieved. A total relief of pain was observed in 19 patients (63%). Mean pain score dropped from 4.2 to 1.3 in patients who suffered predominantly from painful erections. Intercourse satisfaction improved in 11 patients after therapy. Mean angulation before (40 degrees ) and after (37 degrees ) ESWT did not change significantly. Late follow-up after 11.1 months (4-17 months) could be completed in 36 patients. In total, 19 men reported that ESWT improved their PD. Of these, 16 noted no change. Only one of the patients noticed a worsening of his disease during or after treatment. Complication rate was low with only minor side effects such as minimal skin bruising; one urethral bleeding occurred. ESWT did reduce pain during erection in patients suffering mainly from painful erection due to PD. However, penile angulation did not improve significantly in our setup and thus intercourse difficulties did improve only in 28% of the patients. Therefore, we do not recommend ESWT as a primary treatment for PD.

Treatment of varicocele: a prospective randomized comparison of laparoscopy versus antegrade sclerotherapy.

OBJECTIVES: To compare the therapeutic success, the morbidity and the costs of antegrade sclerotherapy versus laparoscopic varicocelectomy. METHODS: Seventy-six consecutive varicocele patients were randomly assigned to two treatment arms. Preoperative and 3 month postoperative sperm density, motility and morphology were analysed. The diagnosis of the varicocele was established clinically and with Doppler ultrasonography. RESULTS: Fifty-eight patients treated by either of the two methods were followed up. The recurrence rate increased progressively with the size of the varicocele in both groups. The postoperative incidence of complications particularly hydrocele formation was significantly higher in the laparoscopic group. The costs of the disposable material for laparoscopic varicocelectomy was twice as high as for sclerotherapy. CONCLUSIONS: Antegrade sclerotherapy is the less invasive treatment method of male varicocele with lower costs and better outcome and should therefore be the preferred treatment method for male varicocele.

In vitro resistance of Bacillus anthracis Sterne to doxycycline, macrolides and quinolones.

Bacillus anthracis is a potential biological warfare agent. Its ability to develop resistance to antimicrobial agents currently recommended for the treatment of anthrax infection is a major concern. B. anthracis Sterne was grown from a live veterinary vaccine and used it to test for the development of resistance after 21 sequential subcultures in sub-inhibitory concentrations of doxycycline and three quinolones (ciprofloxacin, alatrofloxacin and gatifloxacin) and 15 sequential subcultures in sub-inhibitory concentrations of three macrolides (erythromycin, azithromycin and clarithromycin). After 21 subcultures the minimal inhibitory concentrations (MICs) increased from 0.1 to 1.6 mg/l for ciprofloxacin, from 1.6 to 12.5 mg/l for alatrofloxacin, from 0.025 to 1.6 mg/l for gatifloxacin and from 0.025 to 0.1 mg/l for doxycycline. After 15 passages of sequential subculturing with macrolides, the MICs increased from 12.5 to 12.5 or 50.0 mg/l for azithromycin, from 0.2 to 1.6 or 0.4 mg/l for clarithromycin and from 6.25 to 6.25 or 50 mg/l for erythromycin. After sequential passages with a single quinolone or doxycycline, each isolate was cross-tested for resistance using the other drugs. All isolates selected for resistance to one quinolone were also resistant to the other two quinolones, but not to doxycycline. The doxycycline-resistant isolate was not resistant to any quinolone.

Transient paralysis of the bladder due to wound botulism.

In the last 10 years, wound botulism has increasingly been reported and nearly all of these new cases have occurred in injecting-drug abusers. After absorption into the bloodstream, botulinum toxin binds irreversibly to the presynaptic nerve endings, where it inhibits the release of acetylcholine. Diplopia, blurred vision, dysarthria, dysphagia, respiratory failure and paresis of the limbs are common symptoms of this intoxication. Surprisingly and despite the well-known blocking action of the botulinum toxin on the autonomic nerve system, little attention has been paid to changes in the lower urinary tract following acute botulinum toxin poisoning. Here we report a case of bladder paralysis following wound botulism. Early diagnosis and adequate management of bladder paralysis following botulism is mandatory to avoid urologic complications. Accordingly, the prognosis is usually favorable and the bladder recovery complete.

Spontaneous perirenal hemorrhage after rupture of an aneurysm in case of polyarteritis nodosa along with anuric renal failure. Case report and review of the literature.

We report a case of massive perirenal hemorrhage owing to an inferior segmental arterial rupture of an aneurysm, alongside a primarily inapparent polyarteritis nodosa associated with hepatitis B and C. We come to speak of the diagnostic procedure such as angiography, computerized tomography and MRI as well as the intervening measures like catheter embolization and surgical revision.

[Endotoxinemia in liver cirrhosis]. / Endotoxinämie bei Leberzirrhose

Endotoxins of gram-negative bacteria and of intestinal origin, insufficiently cleared by the hepatic reticulo-endothelial system are of an increasing interest within the pathogenesis of liver diseases. With purpose to obtain data concerning incidence and course of endotoxaemia in patients with liver cirrhosis an unselected group of these patients, sequentially admitted, was investigated by means of the Limulus-gelation test, regarded as most sensitive to endotoxins. At the admittance, 65% of the patients had endotoxaemia, further 14% developed endotoxaemia later. In total 79% of the patients investigated had endotoxaemia.---Bleeding from oesophageal varices was associated with endotoxaemia in 78%, functional renal impairment in 75%, consumption coagulopathy in 81%, encephalopathy in 77% and a pyrogen reaction in 82% of the patients. Regarding the Limulus assay, the dilution technique was more sensitive in detection of free endotoxaemia as opposed to the chloroform extract. It is concluded from the results that endotoxaemia in patients with liver cirrhosis is frequent and has to be viewed as relevant within the pathogeneses of chronic liver diseases.
