A comparison of competing methods for the detection of surgical-site infections in patients undergoing total arthroplasty of the knee, partial and total arthroplasty of hip and femoral or similar vascular bypass

Recent research suggests that the retrospective review of the International Classification of Disease (ICD-9-CM) codes assigned to a patient episode will identify a similar number of healthcare-acquired surgical-site infections as compared with prospective surveillance by infection control practitioners (ICP). We tested this finding by replicating the methods for 380 surgical procedures. The sensitivity and specificity of the ICP undertaking prospective surveillance was 80% and 100%, and the sensitivity and specificity of the review of ICD-10-AM codes was 60% and 98.9%. Based on these results we do not support retrospective review of ICD-10-AM codes in preference prospective surveillance for SSI. (C) 2004 The Hospital Infection Society. Published by Elsevier Ltd.

Surgical resection of retrobulbar infiltrative lipomas in two dogs

Two dogs were presented for referral with nonpainful exophthalmia due to a retrobulbar mass. Incisional biopsies confirmed a histological diagnosis of infiltrative lipoma in both cases. Infiltrative lipomas are rare tumours of soft tissues and are invasive to adjacent tissue. Wide surgical resection is required to prevent local recurrence of the disease. Computed tomography of the head was performed in both cases to evaluate the extent of the masses and to plan surgical resection. Both dogs underwent a partial orbitectomy and were disease free 24 and 21 months later. The cosmetic appearance was good and both dogs maintained vision in the affected eyes.

Soft tissue sarcomas in dogs: A study assessing surgical margin, tumour grade and clinical outcome

The purpose of this prospective clinical study was to quantify the surgical margin necessary to maximise local disease control for canine soft tissue sarcoma of various grades. This was achieved via gross and histopathologic studies. Fourteen dogs underwent surgical treatment for 15 localised, measurable, subcutaneous sarcomas. Surgery and histopathologic evaluation were performed to standardised protocols. Regular examinations for local recurrence and distant metastases were performed for at least 12 months postoperatively. One hundred percent local disease control was achieved with deep margins >10mm and 93% one year disease-free survival with wide margins (i.e. >10mm laterally and one fascial plane or >10mm in depth). There was one case of recurrence. Fascial planes appear to act as biological barriers to local tumour invasion but this protective effect may be overcome with high-grade lesions.

Canine intra-nasal squamous cell carcinoma treated with chemotherapy prior to surgical resection

A 12-year-old male castrated Samoyed dog was presented with left-sided epistaxis and sneezing. Diagnostic procedures included haematology and biochemistry testing, thoracic radiography, fine needle aspiration of regional lymph nodes, CT, rhinoscopy, incisional biopsy and histopathology. Squamous cell carcinoma of the rostral nasal cavity was diagnosed, with no evidence of metastatic disease. External beam radiation was not an accessible treatment option. Complete surgical resection of the tumour would have required a larger, more disfiguring resection of nasal planum and maxilla than the owner was prepared to accept and may have been associated with an unacceptable morbidity. As an alternative, the extent of disease was reduced using a combination of carboplatin, doxorubicin and piroxicam chemotherapy. This allowed a less extensive nasal planum removal to be performed to remove residual disease with clean margins. The patient achieved a 14 month disease free interval from the time of surgery to the time of local recurrence. Survival time from diagnosis to eventual euthanasia for progressive local disease was 18 months.

The surgical management of consecutive exotropia

Purpose: To review the results and techniques of surgical treatment of consecutive exotropia. Methods: We performed a retrospective chart review of all patients who underwent surgery for consecutive exotropia in a pediatric ophthalmology practice between 1992 and 2001. Patients were excluded if follow-up lasted < 6 weeks or if exotropia was caused by other ocular disorders such as previous trauma or congenital cataracts. Results: Fifty-nine patients were identified. The procedure performed in the majority of cases was unilateral lateral rectus recession and medial rectus advancement to the original insertion. Seven patients underwent bilateral lateral rectus recession, and 6 underwent lateral rectus recession combined with medial rectus resection. The mean interval between original surgery and surgery for consecutive exotropia was 14.1 years (range 4 months to 47.5 years). The mean preoperative distance exodeviation was 31.7 prism diopters (PD). Satisfactory alignment lie, within 10 PD of orthophoria) was achieved in 36 patients (61%) at week 1 and 42 patients (71%) at final follow-up. Mean follow up was 16.0 months. Thirty-nine patients (66%) demonstrated an exodrift after surgery (mean 7.6 PD). Conclusion: Consecutive exotropia may occur many years, even decades, after esotropia surgery. Lateral rectus recession with advancement of the previously recessed medial rectus is an effective treatment. An exotropic drift occurs after consecutive exotropia surgery, usually within the first 6 weeks. A suitable ocular alignment immediately after surgery for consecutive exotropia is a small-angle esotropia of 5 to 10 PD.

A randomized, controlled trial to determine the efficacy of paper tape in preventing hypertrophic scar formation in surgical incisions that traverse Langer's skin tension lines

Background: How a scar is managed postoperatively influences Its cosmetic outcome. After Suture removal, scars are susceptible to skin tension, which may be the trigger for hypertrophic scarring. Paper tape to support the scar may reduce multidirectional forces and prevent hypertrophic scarring. Methods: Seventy patients who had under gone cesarean section at the Royal Brisbane and Women's Hospital were randomized to treatment and control groups. Patients in the control group received no postoperative intervention. Patients in the treatment group applied paper tape to their scars for 12 weeks. Scars were assessed at 6 weeks, 12 weeks, and 6 months after surgery using Ultrasound to measure intradermal scar volume. Scars were also assessed using the International Clinical Recommendations. Results: Paper tape significantly decreased scar volume by a mean of 0.16 cm(3), (95 percent confidence Interval, 0.00 to 0.29 cm(3)) At 12 weeks after surgery, 41 percent of the control group developed hypertrophic scars compared with none in the treatment group (exact test, p = 0.003). In the treatment group, one patient developed a hypertrophic scar and four developed stretched scars only after the tape was removed. The odds of developing a hypertrophic scar were 13.6 times greater in the control than in the treatment group (95 percent confidence interval, 3.6 to 66.9). Of the 70 patients randomized, 39 completed the study. Four patients in the treatment group developed a localized red rash beneath the tape. These reactions were minor and transient and resolved without medical intervention. Conclusions: The development of hypertrophic and stretched scars in the treatment group only after the tape was removed suggests that tension acting on a scar is die trigger for hypertrophic scarring. Paper tape is likely to be an effective modality for the prevention of hypertrophic scarring through its ability to eliminate scar tension.

Pressure support ventilation with the ProSeal (R) laryngeal mask airway. A comparison of sevoflurane, isoflurane and propofol

Background and objective: There are no data about the influence of anaesthetics on cardiovascular variables during pressure support ventilation of the lungs through the laryngeal mask airway. We compared propofol, sevoflurane and isoflurane for maintenance of anaesthesia with the ProSeal (R) laryngeal mask airway during pressure support ventilation. Methods: Sixty healthy adults undergoing peripheral musculo-skeletal surgery were randomized for maintenance with sevoflurane end-tidal 29%, isoflurane end-tidal 1.1% or propofol 6 mg kg(-1) h(-1) in oxygen 33% and air. Pressure support ventilation comprised positive end-expiratory pressure set at 5 cmH(2)O, and pressure support set 5 cmH(2)O above positive end-expiratory pressure. Pressure support was initiated when inspiration produced a 2 cmH(2)O reduction in airway pressure. A blinded observer recorded cardiorespiratory variables (heart rate, mean blood pressure, oxygen saturation, air-way occlusion pressure, respiratory rate, expired tidal volume, expired minute volume and end-tidal CO2), adverse events and emergence times. Results: Respiratory rate and minute volume were 10-21% lower, and end-tidal CO2 6-11% higher with the propofol group compared with the sevoflurane or isoflurane groups, but otherwise cardiorespiratory variables were similar among groups. No adverse events occurred in any group. Emergence times were longer with the propofol group compared with the sevoflurane or isoflurane groups (10 vs. 7 vs. 7 min). Conclusion: Lung ventilation is less effective and emergence times are longer with propofol than sevoflurane or isoflurane for maintenance of anaesthesia during pressure support ventilation with the ProSeal (R) laryngeal mask airway. However, these differences are small and of doubtful clinical importance.
