Timing of intra-lesion shaving for surgical treatment of chronic tophus.

OBJECTIVES: Gouty arthritis results from the deposition of monosodium urate crystals in synovial spaces. The literature shows that a tophus may require surgical treatment to improve cosmesis or function, to alleviate pain, to eradicate sinus drainage or to remove large urate deposits. However, forceful curettage to remove tophus particles embedded in the thin attenuated skin flap may compromise blood circulation and cause other complications. This series presents the experience of the authors in performing intra-lesion shaving during the surgical treatment of tophus patients. METHODS: This study analysed 147 surgical procedures performed in 108 patients with chronic tophus at a single hospital during November 2000 to July 2010. All patients underwent a soft-tissue shaver-assisted intra-lesion excavating technique developed by the authors. Bimanual palpation of the skin was performed to avoid trauma to the skin envelope. The shaving technique proved to be a simple and efficient method of reducing the total urate burden in the body. RESULTS: Compared to conventional surgical treatment, the shaver technique is a safer and more effective option for treating tophus lesions. In this series, wound cultures were positive in 18.4% of operations. Patients with positive wound cultures and chronic renal impairment had significantly longer hospital stays compared to patients with negative wound cultures and patients without chronic renal impairment (P=0.0019 and P=0.0045, respectively); patients with C-reactive protein (CRP)<5 mg l(-1) and white blood cell (WBC) count<10,000 µl(-1) had significantly shorter hospital stays compared to patients with CRP>5 mg l(-1) and WBC>10,000 µl(-1) (P=0.0002 and 0.006, respectively). The upper extremities group and the upper-lower extremities group had significantly shorter hospital stays compared to the lower extremities group (P=0.001 and P=0.0014, respectively). CONCLUSIONS: Medical treatment to control hyperuricaemia is important for reducing the risk of an acute attack of tophus formation. However, the data in this series show that surgery should be performed before the skin becomes ulcerated and before the tophus mass becomes infected. The proposed shaver technique markedly reduces tophus of the extremities with minimal surgical complications.

Management of recurrent ischial pressure sore with gracilis muscle flap and V-Y profunda femoris artery perforator-based flap.

BACKGROUND: Inappropriate seating has been implicated as a major contributing factor in ischial pressure-sore recurrence. During their lifetime, paraplegic patients may require several flaps for closure of the same or some other adjacent pressure sore. Despite a wide variety of flap reconstruction options being described, the ischium remains the most difficult pressure-sore site to treat. METHODS: From June 1998 to July 2006, there were 253 pressure-sore patients operated upon at Kaohsiung Medical University Hospital. Ten patients (eight men and two women) suffered from recurrent ischial pressure sores, and all of them received more than one flap reconstruction for the ischial defect. For the treatment of the recurrent ischial pressure sore, gracilis muscle flap and readvancement of the V-Y profunda femoris artery perforator-based flap were used to fill the dead space as well as cover the defect. RESULTS: Among these 10 recurrent ischial pressure-sore patients, six of them had suffered bilateral ischial ulcers. Eight of them had previous sacral pressure sores. In all, 32 flap reconstruction procedures were performed on these 10 patients. Unfortunately, one patient had recurrent grade II bilateral ischial pressure sores after 11 months of ulcer-free period. The other nine patients had no recurrence noted, and enjoyed their lives with an average 27.2 months ulcer-free period (range 9-53 months). CONCLUSIONS: The fasciocutaneous flap provides a higher mechanical resistance than the detached and transposed muscle. However, for the recurrent ischial ulcer patients, readvancement of the perforator-based fasciocutaneous flap alone cannot provide adequate bulk to obliterate the 'dead space' after debridement of the bursa and the surrounding necrotic tissue. By combining the readvancement of V-Y profunda femoris artery perforator-based fasciocutaneous flap and gracilis muscle flap, these recurrent ischial ulcers will heal without complication. Recurrence of ulceration often develops despite successful flap closure. Patients and their relatives have to be educated regarding pressure relief, personal skin, and self-care. Surgeons must collaborate with the rehabilitation department, nursing staffs, and social workers to improve long-term results.

Influencing factors of outcome after lower-limb amputation: a five-year review in a plastic surgical department.

The crude major lower limb amputation procedure rate is 8.8 per 100,000 of the population per year in Taiwan. From January 2002 to October 2006, patients that received major lower limb amputation in our department were enrolled in this study. Retrospective chart reviews concerning different factors that can affect the eventual postoperative functional status were investigated. Factors that affected the length of hospital stay included duration before amputation (P < 0.001) and renal function (P = 0.045). Phantom limb pain was affected by wound healing time (P = 0.006). Factors that affected the daily prosthesis usage time were initial infection status (P = 0.021), renal function (P = 0.01), patient educational level (P = 0.016), and pretraining waiting time (P = 0.003). The duration of prosthetic training was affected by patient educational level (P = 0.004) and marital status (P = 0.024). In addition, subjective satisfaction about the usage of prosthesis was affected by pretraining waiting time (P = 0.001) and daily prosthesis usage time (P < 0.001). The daily prosthesis usage time was closely related to life quality improvement (P < 0.001) and subjective satisfaction of prosthesis usage (P < 0.001). Despite reported unchangeable factors like age, end-stage renal disease, dementia, coronary artery disease, and level of amputation, preprosthesis training waiting time significantly affected the satisfaction and daily usage time of the prosthesis. Surgeons can make some contribution to accelerate amputation wound healing and stump maturation by choosing the correct operating procedure, delicately managing the soft tissue, and ascertaining proper wound care to improve the outcome.

Experiences of interprofessional implementation of a healthcare matrix.

The Taiwan Joint Commission on Hospital Accreditation endorsed the Institute of Medicine (IOM) dimensions of health care quality as safe, timely, effective, efficient, equitable, and patient-centered. The Taiwan Association of Medical Education has also adopted the Accreditation Council for Graduate Medical Education (ACGME) outcome project and core competencies for Taiwan physicians in training. These schemes focus on patient care, medical knowledge and skills, interpersonal and communication skills, professionalism, system-based practice and practice-based learning and improvement. Bingham (2004) described a Healthcare Matrix that links to the ACGME Core Competencies and the IOM Dimensions of Quality as a tool to improve health care. The matrix provides a blueprint to help residents learn the core competencies in patient care, and to help the faculty to link mastery of the competencies with improvements in quality of care. However, the "six-by-six" framework was too complicated to fill in. Furthermore, the translation of the IOM aims and ACGME core competencies into the Chinese language seemed incoherent and difficult to remember. We simplified the matrix by merging some columns of the original Healthcare Matrix, and reduced the 6 x 6 form into a 4 x 5 framework. The matrix was applied in case conferences, mortality and morbidity conferences, combined meetings and nursing quality assurance meetings in different departments. This format organizes the presentation and discussion, highlighting strengths or deficiencies in key aspects of patient care. With interprofessional collaboration, the matrix has been used in the departments of Plastic Surgery, and Nursing and Performance Management in our hospital. The achievements are encouraging. The Taiwan Edition Healthcare Matrix is worthy of consideration, having been used in a Mandarin-speaking region of Asia.

"Shift to right flypaper technique" a refined method for postage stamp autografting preparation.

"Lack of donor skin" is a challenge condition for autografting in the treatment of extensive burns. The modified Meek technique seems to be a practical solution for this problem. However, the equipment and consumed materials for the modified Meek technique are expensive which limits routine use. Designing a less expensive, efficient and easy to apply expansion method may improve burn care quality and shorten hospital stay period. Our previous study reported the "flypaper technique" for preparation of postage stamp autografting. The time for confluence of the burned wound depends on the size of the skin islands and expansion ratio. In clinical practice, 5mm skin squares is the preferred size of the skin islands; however, the positioning procedure can be modified to improve the wound healing process. According to the chessboard diagram, the "shift to right" positioning technique shortens the 10% biggest distance in six times expansion diagrams and 20% biggest distance in nine times expansion diagrams. By using a quick cutting plate, chessboard tray and petrolatum gauze, the skin islands can be uniformly located and correctly oriented on the gauze. This method allows a true expansion ratio up to nine times. In comparison with the modified Meek technique, this method also offers rapid wound reepithilization but with lower cost. However, the burn scar needs further rehabilitation and compression therapy to improve the functional and cosmetic result. This "shift to right flypaper technique" is worthy of consideration in dealing with extensive burns.
