Clinical comparative study of Aquacel and paraffin gauze dressing for split-skin donor site treatment

The management of split-thickness skin graft donor sites is targeted towards promoting the healing process, while minimizing adverse effects and complications. The aim of this study was to compare donor site treatment outcome between Aquacel, a carboxymethylcellulose-based hydrofiber dressing, and the standard mesh paraffin gauze dressing. The study included 23 adult patients. Half of the skin graft donor site in the proximal thigh was dressed with paraffin gauze and the rest with Aquacel. The results indicated that patients treated with Aquacel experienced significantly less pain and a more rapid rate of epithelialization compared with patients treated with mesh paraffin gauze dressing. Final scarring (ie, after the 1-year follow-up) was significantly better with the Aquacel dressing. We conclude that Aquacel dressing is superior to the standard mesh paraffin gauze dressing for split-thickness donor site area in pain relief, ease of treatment, promotion of epithelialization, and the quality of scarring.

A review of the applications of the hydrofiber dressing with silver (Aquacel Ag®) in wound care

Aquacel Ag((R)) (ConvaTec, Princeton, NJ, USA) is a new hydrofiber wound dressing consisting of soft non-woven sodium carboxymethylcellulose fibers integrated with ionic silver. It is a moisture-retention dressing, which forms a gel on contact with wound fluid and has antimicrobial properties of ionic silver. We present a current literature review on Aquacel Ag((R)), of both in vitro and in vivo efficacy and clinical applications. In vitro and in vivo studies have demonstrated the wide antimicrobial properties of Aquacel Ag((R)), and additionally demonstrated the cytotoxicity of ionic silver to keratinocytes and fibroblasts that cause delay in wound re-epithelialization. Clinical studies confirmed that Aquacel Ag((R)) is an effective and safe dressing for a variety of wound types, both acute and chronic. Incorporation of ionic silver into the hydrofibers does not cause undue alteration in the performance properties of the base dressing, which continues to provide favorable wound moisture and exudate management. The addition of ionic silver reduces local pain and dressing changes, and provides significant broad-spectrum antimicrobial properties, with no delay in wound healing.

The S Nipple-areola Reconstruction

Nipple reconstruction is performed as a last stage in breast reconstruction following mastectomy. Various methods of nipple reconstruction have been described, most of them utilizing either free composite grafts or local flaps. The main problem encountered using either method is the gradual absorption and flattening of the nipple. The technique we used in reconstructing 22 nipples, in preference over the various methods accepted in breast reconstruction, achieves a long-standing, protruding nipple constructed from two large local flaps raised from an S-shape design. The technique is simple and permits freedom in choosing the height of the nipple, even in the presence of a mastectomy scar. The size of the nipple thereby constructed is in excess of what was expected. Shrinkage occurs during the first 2 months, and the resulting size is more than adequate. The areola is reconstructed by a full-thickness skin graft harvested from a nonhairy area of the upper inner thigh. The local flaps lack the necessary color, which is achieved by tattooing.

Serious Infectious Complications of Midsternotomy: A Review of Bacteriology and Antimicrobial Therapy

49 patients with severe infectious complications of midsternotomy incision were treated at our referral center over a 3-year period. 43 species of microorganisms were identified in 38 patients, the most common being Pseudomonas aeruginosa (37%) and Staphylococcus aureus (30%). Most of the patients underwent aggressive debridement and chest wall reconstruction by muscle transposition in combination with antimicrobial therapy. Antimicrobial therapy was given perioperatively according to the in vitro susceptibility of the organisms. Treatment was continued beyond this period for 2-3 weeks in patients with extensive deep seated infection or in those with positive cultures from intraoperative specimens. Some patients needed a longer course of up to 6-8 weeks antimicrobial therapy because of insufficient response to the shorter course. In all, 45/49 patients had complete wound healing. 28 recovered within 2-5 weeks and 16 required a more protracted course with additional surgery in 8; 1 wound did not heal after 20 months and 4 patients died from non-infectious complications. Due to the lack of specific guidelines in the literature as to the proper choice and length of administration of antimicrobial therapy for midsternotomy wound infection, and in view of these favorable results, we recommend our protocol in the treatment of midsternotomy wound infection (in combination with appropriate surgery).

Treatment of earlobe keloids by extralesional excision combined with preoperative and postoperative "sandwich" radiotherapy.

Background: Earlobe keloids can form after cosmetic ear piercing, trauma, infection, or burns, or spontaneously. These keloids are highly resistant for treatment and are followed by severe cosmetic implications. There are various surgical and nonsurgical treatment modalities for earlobe keloids, with no universally accepted treatment policy and a wide range of reported recurrence rates. The authors present their experience of treating earlobe keloids using the “sandwich” technique protocol; extralesional excision and external-beam radiotherapy are given a day before and a day after the operation. Methods: The authors retrospectively reviewed all patients with earlobe keloids treated by the “sandwich” technique between the years 1996 and 2005. Patients were categorized into two groups: a high-risk group for previously treated patients and patients with a tendency for hypertrophic scars and keloids, and a low-risk group for the others. All patients underwent extralesional excision of the keloid and local radiotherapy before the excision and following it. Follow-up was a minimum of half a year and included a patient satisfaction questionnaire and documentation of keloid recurrence or cure. Results: A total of 23 patients were treated by this protocol; 57 percent were male. Patients had an average age of 24 years. The most common keloid etiology was earlobe piercing. Recurrence rates for the low-risk and high-risk groups were 25 and 27 percent [percent of the patients], respectively. Overall patient satisfaction was high. Conclusion: The combined excision and “sandwich” radiotherapy technique is a simple and effective method for treating earlobe keloids, with high patient satisfaction and low recurrence and complication rates.

Our experience with Wisebands: a new skin and soft-tissue stretch device.

Complex wounds that involve skin and soft-tissue defects that are unsuitable for primary closure by conventional suturing are common in the field of surgery. Among the many surgical options available to overcome these problems are various mechanical devices that have recently been proposed for delayed primary closure of such wounds. The authors present their experience with a new complex wound closure device, Wisebands, a device uniquely designed for skin and soft-tissue stretching. During the last 2 years, the authors have treated 20 patients with 22 skin and soft-tissue wounds for which primary closure was not feasible. The Wisebands devices were applied to the wounds, stretching the skin and underlying soft tissue, gradually closing the defects until the edges were sufficiently approximated for primary closure. Successful wound closure was achieved in 18 patients (90 percent). The Wisebands devices were removed in two patients (10 percent) because of major wound complications. In two other patients (10 percent), minor wound complications had occurred that did not necessitate removal of the device. At a mean follow-up of 1 year (range, 10 months to 2 years), stable scarring with no functional or significant aesthetic deficit was achieved. The authors conclude that the Wisebands device facilitates closure of complex skin and soft-tissue wounds, with low morbidity and complication rates, and can provide the surgeon with another important tool for closing complex wounds. Nevertheless, appropriate patient selection, intraoperative judgment, and close postoperative care are essential to ensure closure and avoid undue complications.

Median sternotomy wound complication : The effect of reconstruction on lung function

The objective of the study was to evaluate the lung function of patients with median sternotomy wound complication during the early postmedian sternotomy period and to compare the long-term pulmonary effects of reconstruction using pectoralis major and rectus abdominis muscle flaps. The percentage of predicted, standardized forced vital capacity (FVC); the standardized forced expiratory volume in 1 second (FEV1), and FEV1/FVC ratios of 45 patients with a median sternotomy wound complication were evaluated before and at a mean time of 10.6 months after wound reconstruction. Both mean FVC and FEV1 increased after wound revision compared with the prereconstruction results (8.4% and 9.2% increase, respectively). Patients with painful chest wall movement had the worst (60%) mean FVC and FEV1 before reconstruction when compared with a nonpainful complication. Reconstruction with a muscle flap was followed by an increase of 8.6% and 7.3% in FEV1 and FVC, respectively, from prereconstruction results. However, long-term results indicate that these patients have a mild, restrictive impairment of their lung function tests (LFTs), with about 80% of the predicted FVC and FEV1. Among the muscle flaps, the best improvement and best longterm LFT results were after sternectomy and reconstruction with a pectoralis major muscle flap as compared with a rectus abdominis muscle flap. Sternectomy and reconstruction with a muscle flap is a well-tolerated procedure associated with improvement of lung function compared with prereconstruction values. A pectoralis major muscle flap should be the first choice for muscle flap reconstruction while a rectus abdominis muscle flap should be reserved only for patients with good LFTs before reconstruction.

Malignant melanoma and pregnancy: second thoughts.

Malignant melanoma (MM) was considered a hormone-sensitive tumour, and pregnancy was thought to increase its risk and cause faster progression and earlier metastasis. Several controlled studies demonstrated similar survival rates between pregnant and non-pregnant patients and concluded that early reports of advanced MM of pregnancy were probably due to late diagnosis. We retrieved information from our database between 1997 and 2006 on all patients diagnosed as having MM during and up to 6 months after pregnancy (n=11) and compared them to age-matched, non-pregnant, MM patients (n=65, controls) treated by us during that period. The mean Breslow thickness was 4.28mm for the pregnant patients and 1.69mm for the controls (p=0.15). The sentinel nodes were metastatic in five pregnant patients compared to four controls (p<0.0001). Two patients in the pregnancy group and one control died of MM (p=0.0532). Our results indicate a negative effect of pregnancy on the course of MM.

Clinical-radiological evaluation of poststernotomy wound infection.

&NA; The presumption that computed tomography is the “gold standard” imaging method for diagnosing poststernotomy sternal wound infection was never validated. This study was designed to evaluate the accuracy and role of computed tomography in diagnosing the extent of infectious complications following sternotomy. A high postoperative infection recurrence rate in our earliest cases (30 percent, 1984 to 1988) motivated us to assess whether this modality enables the surgeon to choose the optimal surgical approach, which will make it possible to reduce morbidity and mortality rates. Two‐hundred three patients with poststernotomy sternal wound infections were operated upon between 1984 and 1993. All pertinent clinical and radiological data of these patients were collected retrospectively and reinterpreted by an unbiased radiologist; the radiological data were correlated both to the intraoperative clinical findings and to histological interpretation of the surgical specimens. The study group available for statistical analysis included 160 patients. Predictive statistical analysis confirmed that computed tomography is a highly reliable imaging method for identifying the different pathologies as soft tissue, sternum mediastinal infections, in sternal wound infection with overall sensitivity of 93.5 percent and specificity of 81.7 percent. New radiographic findings were identified for the distinction of costochondral infection. This complication was, and still is, a major deceptive clinical problem in these patients and the major contributor to recurrences. We propose a sternal wound infection classification system that outlines the recommended approach for each clinical‐radiological condition. Since computerized tomography was found to be a highly accurate modality, we strongly believe that the surgeon should take its pathological‐radiographic findings into serious consideration, even if there are no “clear‐cut” clinical signs for an existing or recurring infection.

Simultaneous contralateral breast adjustment in unilateral deep inferior epigastric perforator breast reconstruction.

BACKGROUND Breast symmetry is a key factor in deep inferior epigastric perforator (DIEP) flap breast reconstruction, which necessitates in many cases contralateral breast adjustment, traditionally done at a second stage. We present our experience with simultaneous contralateral breast adjustment in unilateral DIEP breast reconstruction. METHODS We retrospectively reviewed all consecutive unilateral DIEP breast reconstructions done in our institution. The patients were divided into three groups according to contralateral breast surgery performed: simultaneous adjustment, late adjustment, and no contralateral breast adjustment surgery. The groups were compared by aesthetic outcome and patient satisfaction using the BREAST-Q questionnaire. RESULTS A total of 77 unilateral breast reconstructions were performed using the DIEP flap. Fifty-one eligible patients agreed to respond to the questionnaire by telephone and were enrolled in the study; 33 underwent simultaneous contralateral breast adjustment, eight underwent late adjustment procedure, and 10 had no contralateral surgery performed. Aesthetic outcome and patient satisfaction was comparable in the simultaneous and late adjustment groups, but was reduced during the latent period. CONCLUSION Simultaneous contralateral breast adjustment in unilateral DIEP breast reconstruction is a safe and a worthwhile procedure that should be offered to the patient when appropriate.
