Editor's Choice - Treatment of Aortic Prosthesis Infections by Graft Removal and In Situ Replacement with Autologous Femoral Veins and Fascial Strengthening.

INTRODUCTION: Aortic prosthetic graft infection (AGI) is a major challenge in vascular surgery. Eradicating the infection requires prosthetic material removal, debridement, and lower limb revascularization. For the past 15 years, we have used femoral veins for aorto-iliac reconstruction and tensor fascia lata to strengthen the upper anastomosis. OBJECTIVE: The purpose of this single institution retrospective study is to present results regarding in situ replacement of infected aortic grafts with autologous femoral veins (FVs). METHODS: From October 2000 to March 2013, patients treated for AGI with graft removal and autologous FV reconstruction at Helsinki University Hospital were included. Primary outcome measures were 30 day mortality, long-term treatment related mortality, and re-infection rate. Secondary outcome measures were long-term all cause mortality and event free survival (graft rupture, re-intervention, major amputation). RESULTS: During a 13 year period 55 patients (42 male, 13 female) were operated on using a venous neo-aorto-iliac system for AGI. The mean follow up was 32 months (1-157 months). The 30 day mortality rate was 9% (5) and overall treatment related mortality 18% (10). All cause mortality during follow up was 22 (40%) and overall Kaplan-Meier survival was 90.7% at 30 days, 81.5% at 1 year, and 59.3% at 5 years. Graft rupture occurred in three (5%) cases, two of which were caused by graft re-infection (4%). Four patients required major amputation, one of them on arrival and three (5%) during the post-operative period. Nine (16%) patients needed interventions for the vein graft, and two graft limbs occluded during follow up. CONCLUSION: In situ reconstruction for aortic graft infection with autologous FV presents acceptable rates of morbidity and mortality, and remains the treatment of choice for AGI at Helsinki University Hospital.

Treatment of vocal cord granuloma.

Combined surgical and conservative therapy (voice therapy, treatment of infections, allergy, oesophageal reflux, and psychogenic stress) has been used in the treatment of non-specific vocal cord granuloma. Such tumors have a great tendency to recur. The 41 patients with vocal cord granuloma in our study (4 women, 37 men, mean age 56 years) were treated at our hospital during 1980-1986. Nine patients were healed with conservative treatment, 32 were treated by laryngomicrosurgery under general anesthesia and jet-ventilation. The latter group was divided into three treatment groups; 8 of these patients were treated with cryotherapy, 9 with postoperative steroids (Prednisolone 40 mg/day in decreasing doses) and antibiotics, and 15 only with microsurgery. At some phase in their treatment 41% of the patients were able to participate in voice therapy. The most recurrences were found in the group treated with cryotherapy, 2.7 rec./pat.; 1.8 rec./pat. were found in the group that underwent surgery, and 1.7 rec./pat. among the patients treated with steroid-antibiotics. In all three groups, some patients experienced recurrences. In the cryotherapy group, however, recurrent granulomas were large and required reoperation, while those in patients treated with steroid-antibiotics were small and could be cured using conservative therapy. If granuloma does not disturb the voice, cause respiratory obstruction or demand histopathological diagnosis, surgery is contraindicated. Cryotherapy does not help traditional surgery, while steroid-antibiotics administered postoperatively seem to help the healing process.

Articulatory disorders in speech among Finnish-speaking students according to age, sex, and speech therapy.

A group of Finnish-speaking students (n = 451) was examined clinically to study occurrence of articulatory disorders in speech, controlling for the possible effects of age, sex, and previous speech therapy. Distortions of the /s/ sound were found in 16%, of the /r/ sound in 3%, and of the /l/, /n/, or /d/ sounds in about 1% of the subjects; the rarest faultily produced sounds were usually combined with other articulatory disorders. According to fitted log-linear functions, age and sex were not related to prevalence of articulatory disorders in speech among young adults, while there was a tendency for subjects with previous speech therapy to have higher frequencies of articulatory disorders of /s/ and /r/ sounds than subjects with no such treatment, suggesting that exclusion of the treated subjects would have resulted in too low a prevalence of articulatory disorders in the sample.
