Objective: To summarize current Canadian practice patterns in the diagnosis of and interventions for inhalation injuries (INHI).

Methods: A 10-question survey regarding the diagnosis of and interventions for INHI was sent to the medical directors of all 16 burn centres across Canada.

Results: The response rate to the survey was 50%. Fibreoptic bronchoscopy is required for the diagnosis of INHI in only four centres (50%). The departments of intensive care, plastic surgery, otolaryngology and respirology are involved in performing fibreoptic bronchoscopy in 87.5%, 37.5%, 12.5% and 12.5% of Canadian burn centres, respectively. Intubation for INHI is most often based on physical examination results (87.5%) and clinical history (75%). The most common physical features believed to be most consistent with INHI are dyspnea (87.5%) and hoarseness (87.5%). Common treatments include intubation (87.5%), routine ventilatory support (87.5%) and chest physiotherapy (75%). None of the centres used nebulized heparin. A total of five centres (62.5%) routinely changed the fluid resuscitation protocol when INHI was diagnosed. Only two centres (25%) routinely used prophylactic antibiotics for INHI.

Conclusion: Prospective, multicentre trials are needed to generate evidence-based consensus in the areas of diagnosis, grading and treatment for INHI in Canada.

Reduction mammoplasty is one of the most commonly performed procedures in plastic surgery. Occasionally, there are findings reported by pathologists that are unfamiliar to the treating surgeon. The aim of the present study was to determine the types of pathologies encountered in reduction mammoplasty specimens. From this list of diagnoses, a best practice guideline for management will be organized to better assist plastic surgeons in the management of patients with incidental findings on pathology reports. A total of 441 pathology reports from patients who underwent bilateral or unilateral reduction mammoplasty in the past three years were identified. A list of 21 different pathologies was generated from the pathology reports, along with supplemental data from recent texts and articles. Occult carcinomas were encountered in two cases (0.45%) and high-risk lesions were found in three cases (0.68%) at the authors' institution. An algorithm was then constructed to organize the pathologies according to risk of malignancy and assign them to a management guideline. There are many different lesions encountered incidentally in reduction mammoplasty specimens that may or may not confer some cancer risk. It is important for plastic surgeons to know which lesions need closer follow-up to provide the best care for their patients.

Background: Changes in sleep architecture are common phenomena observed in post-traumatic patients; such altered sleeping patterns have negative implications on various phases of rehabilitation. Sleep is an essential process, without which one cannot function effectively and, hence, any aberrations in the quality of sleep in such patients need to be critically analyzed.

Objective: To probe the quality of sleep in postburn patients at one year compared with a group of adequately matched controls.

Methods: Quality of sleep in postburn patients at one year was measured using the Pittsburg Sleep Quality Index questionnaire and compared with a group of adequately matched controls. Data were tabulated and subjected to statistical analysis using Pearson's χ(2) test.

Results: The relationship between the postburn state and sleep disturbances was found to be statistically significant. Other relevant parameters are also highlighted and discussed.

Discussion: Sleep is one of aspect of functioning that may be least taken into account by professionals during the phase of postburn rehabilitation because more obvious threats receive preferred treatment. Unless these problems are dealt with in the postburn period, rehabilitation can never be complete.

Conclusion: Postburn patients experience significant changes in sleep architecture, which need to be taken into account to enable complete rehabilitation of the patient.

The transverse upper gracilis free flap is a well-described option for breast reconstruction. The technique is a secondary choice for autologous breast reconstruction because the abdomen remains the primary donor site for breast reconstruction. However, in appropriately selected patients, the authors believe that the transverse upper gracilis flap remains a reliable flap for breast reconstruction. Its consistent anatomy, potentially reasonable donor site scar, limited functional morbidity and simultaneous two-team surgical approach make this flap a viable option for many patients. The technique, however, is not without drawbacks - known numbness of the medial thigh and the potential for chronic lymphedema of the lower leg, contour deformities of the medial thigh, and widening of the medial thigh scar need to be considered. The current article presents a harvest technique that is reliable, rapid and addresses each of the above-mentioned limitations with specific changes in the traditional technique. The article provides video documentation of the modified harvest technique using only monopolar cautery for the dissection.

Women with hypertrophic breasts often experience body pain and posture problems, which tend to be reduced or even eliminated after reduction mammoplasty. The present study aimed to analyze the effects of reduction mammoplasty on anthropometric variables, body posture and pain in women with breast hypertrophy. Eleven women (mean [± SD] age 31.3±10.4 years) participated in the present study. Anthropometric variables, body posture and pain perception were evaluated pretest, and 60 (post60) and 90 (post90) days after reduction mammoplasty. Commercially available posture analysis software was used to analyze the following variables: acromial horizontal alignment (AHA), angle between acromial and anterior superior iliac spines (A-AAIS), vertical alignment of right (R) and left (L) trunk (VAT), vertical alignment of R and L body (VAB) and horizontal alignment of R and L pelvis (HAP). Descriptive statistics and ANOVA for repeated measures were used, and effect sizes (ES) were measured; the level of significance was set at P<0.05. There were no significant differences in anthropometric variables among the assessments. Only HAP-R showed a significant decrease; however, when analyzed, ES, VAT- L and HAP- L in post60, and VAT-R, VAT-L, HAP-R, HAP-L and VAB-L in post90 showed large ES after mammoplasty (ES>0.70). There were significant reductions in pain at post60 and post90 in the neck, cervical spine, back, shoulder and arm (P<0.05). Following mammoplasty, an improvement in body posture, primarily in the alignment of shoulders, trunk and pelvis, and a decrease in pain in the upper limbs and spine, were observed.

Background/objective: Few options, apart from the buttock area, are available for autologous breast reconstruction in thin teenagers. The aim of the present study was to objectively evaluate and compare donor-site morbidity of the inferior gluteal artery perforator (IGAP) flap with that of the previously described inferior gluteal musculocutaneous flap.

Method: A retrospective review of all IGAP flaps for breast reconstruction performed in teenagers between June 2006 and April 2011 at the Centre Hospitalier Universitaire Sainte-Justine, Montreal, Quebec, was performed. Patients were invited to undergo a specific physical evaluation and complete a questionnaire on aesthetic and functional outcomes.

Results: Thirteen records and 11 photographic charts were reviewed. Lateral buttock flattening was noticeable in nine of 11 cases. Three patients experienced some degree of inferior displacement of the gluteal crease. All six patients available for the appointment presented with a zone of dysesthesia or hypoesthesia in the territory of the operated buttock and/or posterior thigh. No motor impairment was found. The questionnaire, completed by eight patients, revealed that six were satisfied or very satisfied with the surgery. Appearance of the operated buttock was rated 3.4 on a scale from 1 to 5 (5 = normal) compared with the normal side.

Conclusions: The IGAP flap remains a suitable option for breast reconstruction in slim teenagers. Similar to the myocutaneous flap, the major donor-site morbidity of the IGAP flap remains sensory impairment involving the posterior femoral cutaneous nerve. There is, however, less visible lateral depression when it is harvested as a perforator flap.

Creation of an aesthetically pleasing nipple plays a significant role in breast reconstruction as a determining factor in patient satisfaction. The goals for nipple reconstruction include minimal donor site morbidity and appropriate, long-lasting projection. Currently, the most popular techniques used are associated with a significant loss of projection postoperatively. Accordingly, the authors introduce the angel flap, which is designed to achieve nipple projection with lasting results. The lateral edges of the flap and the area surrounding the top of the nipple are de-epithelialized and the flaps are wrapped to create a nipple mound composed primarily of dermis. Decreasing the amount of fat within core of the nipple and enhancing dermal content promotes long-lasting projection. Furthermore, the incision pattern fits within a desired areolar size, preventing unnecessary superfluous extension of the incisions. Thus, the technique described herein achieves the goals of nipple reconstruction, including adequate and long-lasting projection, without extension of the lateral limb scars.
