Gracilis muscle transposition for treatment of recurrent anovaginal, rectovaginal, rectourethral, and pouch-vaginal fistulas in patients with inflammatory bowel disease.

BACKGROUND: The aim of this study was to evaluate the effectiveness of gracilis muscle transposition (GMT) to treat recurrent anovaginal, rectovaginal, rectourethral, and pouch-vaginal fistulas in patients with inflammatory bowel disease (IBD). METHODS: A retrospective study was conducted in patients with IBD who had GMT performed by a single surgeon between 2000 and 2018. Follow-up data regarding healing rate, complications, additional procedures, and stoma closure rate was collected. RESULTS: A total of 30 women and 2 men had GMT. In all patients fistula was associated with Crohn's disease. In 1 female patient, contralateral gracilis transposition was required after a failed attempt at repair. The primary healing rate was 47% (15/32) and the definitive healing rate (healed by the time of data collection and after secondary procedures) was 71% (23/32). Additional surgical procedures due to fistula persistence or recurrence were performed on 17 patients (53%).At least 7 patients (21%) suffered complications including one wound infection with ischemia of the gracilis muscle. Stoma closure was successful in 18 of 31 cases of patients with stoma (58% of the patients). CONCLUSIONS: GMT for the treatment of recurrent and complex anorectal fistulas in patients with IBD patient is eventually successful in almost 2/3 of patients.

Patient-reported quality of life in multiple sclerosis differs between cultures and countries: a cross-sectional Austrian-German-Polish study.

BACKGROUND: Patient-reported quality of life (QOL) is an outcome measure in clinical trials in multiple sclerosis (MS), but translated QOL instruments may affect the actual comparability of data. OBJECTIVES: We aimed to investigate possible differences in QOL in MS between cultures and countries. We employed the Functional Assessment of Multiple Sclerosis (FAMS) Version 4 questionnaire, which is a state-of-the-art QOL instrument. METHODS: Some 484 MS patients from Austria (145), Germany (144), and Poland (195) aged 20-60 years, and stratified for sex and disease severity as measured by the Expanded Disability Status Scale (EDSS) score completed the respective FAMS translation and a socio-demographic questionnaire. RESULTS: Analysis of variance and post-hoc Scheffé-test showed that 64% of the FAMS items were answered significantly differently (p < 0.001) between the three countries. A multivariate regression analysis including all the available disease-related and socio-demographic variables revealed the factors age, EDSS score, employment, social contacts, MS course, and country to be significant predictors of both the total FAMS score and the score for items answered differently between the three countries. CONCLUSIONS: Differences exist in the QOL of MS patients from Austria, Germany, and Poland which seem to lie beyond the impact of disease severity. They appear to be related to culture or other country-specific factors, as country was an independent predictor of differently answered items of the FAMS and thus also of the whole FAMS. QOL instruments should consider this aspect to faithfully reflect subjective information such as patient-reported benefit of treatment in multinational clinical trials.

Treatment of type 2 and 4 olecranon fractures with locking compression plate osteosynthesis in horses: a prospective study (2002-2008).

This prospective study describes a series of 18 olecranon fractures in 16 horses that were treated with locking compression plates (LCP). Twelve of the 18 fractures were simple (type 2), whereas six were comminuted (type 4). Six fractures were open and 12 were closed. Each horse underwent LCP osteosynthesis consisting of open reduction and application of one or two LCP. Complete fracture healing was achieved in 13 horses. Three horses had to be euthanatized: two because of severe infection and one because of a comminuted radial fracture 11 days after fixation of the olecranon fracture. Complications encountered after discharge of the horses from the Equine Hospital at the Vetsuisse Faculty (University of Zurich) included implant infection (n=2) and lameness (n=3), which were successfully treated with implant removal. Despite being easier to use, LCP osteosynthesis resulted in a clinical outcome similar to DCP osteosynthesis.

Innovative technique for the closure of rectovaginal fistula using Surgisis mesh.

BACKGROUND: The aim of this prospective study was to analyse the efficacy of Surgisis mesh for closure of rectovaginal fistulas. Prospective data were collected from two centres. METHODS: All patients with a rectovaginal fistula who underwent definitive surgery using Surgisis mesh were prospectively enrolled in this study. Inclusion criteria included a rectovaginal fistula in the lower two-thirds of the rectovaginal septum. Surgery was performed with a standardized technique including combined transrectal and transvaginal excision of the rectovaginal fistula with transvaginal placement of the mesh. Success was defined as closure of both internal and external (perianal and vaginal) openings, absence of drainage without further intervention, and no abscess formation. RESULTS: Over a period of 16 months, a total of 21 mesh procedures were performed in two centres. The mean age of the patients was 47 years (18-59 years). Of the 21 patients, 18 (86%) had recurrent rectovaginal fistula, and the mean number of prior attempts was 2.3 (0-8). The majority of patients (nine) had Crohn's disease-associated fistula, followed by six with iatrogenic fistula, two with radiation-induced fistula, two with obstetric injury-induced fistula, and two with idiopathic fistula. The mesh procedure was performed under faecal diversion in eight patients (38%). The mean operative time was 38 min; no intraoperative morbidity occurred. Patients were discharged from hospital on day 4. After a mean follow-up of 12 months (range, 3-18 months), the overall success rate after primary mesh procedure was 71% (15/21; 6 patients had failure or recurrence). All patients with failure or recurrence were reoperated upon. Out of these six patients who were reoperated upon, four had definite healing (75%). Among the eight patients who had faecal diversion, four (50%) had reversal of their stoma. CONCLUSION: The preliminary success rate for this innovative technique using Surgisis mesh for the closure of rectovaginal fistulas is promising. Further studies are needed to assess the definite role of this novel technique in comparison to traditional surgical procedures.

Fracture configurations of the equine radius and tibia after a simulated kick.

The objective of this postmortem study was to determine the fracture configurations of the equine radius and tibia after a simulated kick. Fracture configurations of 35 radii and 36 tibiae from 19 adult horses were evaluated after a simulated kick in an experimental ex-vivo study. The bones were dissected, the proximal and distal ends were embedded in resin, fixed horizontally and preloaded in compression, and a steel impactor, designed to simulate a shod equine hoof, was dropped from a height of three to six metres onto the diaphysis. The experiments were filmed with a high-speed camera (30,000 pictures/second). The bones were then photographed and radiographed using a C-arm based 3D imaging device. A software programme (Osirix) was used to reconstruct the fissured and fractured bones three-dimensionally on a computer screen for assessment of the fracture configuration and fissure lines. Incomplete fractures occurred in 26 bones and complete fractures in 42. The complete fractures included 22 butterfly and 20 simple fractures; the latter included 17 oblique, two transverse and one longitudinal fracture. Additional longitudinal fissures occurred in 98% of the fractures. The butterfly fragment was always located on the side opposite the impact. There was a significant correlation between the type of bone and the fracture configuration: butterfly and oblique fractures occurred more frequently in the tibia, and incomplete fractures occurred more frequently in the radius. The data collected can be used to optimize evaluation of fractures and fissures caused by a kick and thereby improve surgical stabilization.

Initial experience on efficacy in closure of cryptoglandular and Crohn's transsphincteric fistulas by the use of the anal fistula plug.

BACKGROUND AND AIMS: It was the aim of this prospective study to analyze the efficacy of the Cook Surgisis AFP anal fistula plug (AFP) for the closure of cryptoglandular and Crohn's disease-associated transsphincteric anorectal fistulas. MATERIALS AND METHODS: All patients with transsphincteric anorectal fistulas who underwent a surgical procedure using the AFP were prospectively enrolled in this study. Inclusion criteria included transsphincteric, single-tract fistulas. Patients' demographics, fistula etiology, surgical variables, continence (Cleveland Clinic Florida incontinence score), quality of life (fecal incontinence quality of life), and success rates were prospectively recorded. Surgery was performed in a standardized technique including irrigation of the fistula tract, placement, and internal fixation of the Cook Surgisis AFP anal fistula plug. No flap or excision of the fistula tract was performed. Success was defined as closure of both internal and external openings, absence of drainage without further intervention, and absence of abscess formation. Follow-up information was derived from clinical examination 3, 6, 9, and 12 months postoperatively. RESULTS: Within 6 months (August 2006 to January 2007), a total of 19 AFPs were inserted in 19 patients (8 females, 11 males; mean age, 38 years). Out of 19 patients, 12 had cryptoglandular and 7 had Crohn's associated transsphincteric fistulas. Three patients were smokers, one patient had methicillin-resistant Staphylococcus aureus infection. Mean operative time was 15 min (range, 8-22); no morbidity occurred. After a mean follow-up of 279 days (SD = 68.0) and one patient lost to follow-up, the overall success rate was 61% (12 of 18) at 9 months postoperatively. Focusing solely on cryptoglandular fistulas, the success rate was 45.5% (5 of 11), whereas it was 85.7% (6 of 7) in transsphincteric fistulas associated with Crohn's disease. Five patients with failure of AFP (plug dislodgement, n = 2; persistent secretion, n = 3) had reoperation (27.8%). The reasons for failure were infection requiring drainage (n = 2) and persistent drainage (n = 3). No deterioration of continence was documented. CONCLUSION: The success rate for the Cook Surgisis AFP anal fistula plug for the closure of complex anorectal fistulas both in cryptoglandular and Crohn's associated fistulas was 45.5 and 85.7%, respectively. Further analysis is needed to explain the definite role of this innovative technique in comparison to traditional surgical techniques.

Use of a parathyroid hormone peptide (PTH(1-34))-enriched fibrin hydrogel for the treatment of a subchondral cystic lesion in the proximal interphalangeal joint of a warmblood filly.

To describe the treatment of a subchondral bone cyst in the proximal phalanx with parathyroid hormone peptide-enriched fibrin hydrogel in a warmblood filly. The cyst was localized with computer-assisted orthopaedic surgery, then curetted and finally filled with parathyroid hormone fragment peptide 1-34 (PTH(1-34)) covalently attached to a fibrin hydrogel. The cyst healed quickly without any complications. This result supports the hypothesis that PTH(1-34) delivered locally in a fibrin hydrogel may improve the postoperative prognosis of surgical management of subchondral bone cysts in horses. Subchondral bone cysts are fairly common in horses. Especially in older horses, the prognosis is poor, even after surgical curettage. Therefore, different management protocols have been investigated in conjunction with surgical curettage to improve prognosis. Locally delivered PTH(1-34) seems to be a new method in the treatment of subchondral bone cysts.

Quality of life changes during conformal radiation therapy for prostate carcinoma.

BACKGROUND: The objective of this study was to describe prospectively quality of life (QOL) before and after radiotherapy for patients with prostate carcinoma. METHODS: Forty-three patients with T1-T3 prostate carcinoma who underwent conformal external beam radiation therapy were randomized either to the complete European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaire (EORTC QLQ-C30) or the Medical Outcomes Study Group Short Form Health Survey (SF-36) at baseline, at 3 weeks and 6 weeks after initial treatment, and at 6 weeks and 5 months after the completion of radiotherapy. The measures were self-reported patient QOL, and values are given as the mean +/- standard error of the mean. Changes in QOL are described from baseline to the end of treatment in both questionnaire groups. RESULTS: Emotional role functioning, as measured with the SF-36 questionnaire, significantly improved from 68.2 +/- 9.9 at baseline to 93.3 +/- 5.2 at the end of therapy (P = 0.02). The EORTC QLQ-C30 questionnaire revealed consistent values of emotional functioning during treatment (72.7 +/- 5.9 at baseline) but showed a significant improvement 6 weeks after therapy (89.0 +/- 4.4; P = 0.01). Role functioning deteriorated from 80.1 +/- 6.5 at baseline to 62.5 +/- 8.8 at the end of radiotherapy (P = 0.02). Symptoms of fatigue were shown to increase significantly from 26.9 +/- 6.0 at baseline to 37.7 +/- 7.6 at the end of therapy (P = 0.02). No significant changes in the other dimensions were observed in either questionnaire. CONCLUSIONS: After radiotherapy for prostate carcinoma, patients experience a temporary deterioration of fatigue and role functioning, as measured with the EORTC QLQ-C-30. Despite physical deterioration, the authors observed an improvement in emotional functioning scores with both questionnaires. This may have been due to psychological adaptation and coping.
