Accidental Injection of Freund Complete Adjuvant With Mycobacterium Tuberculosis.

Accidental needlestick injuries are common in laboratory and health care workers. Injection of atypical pathogens, such as those encountered in the animal laboratory setting, may pose considerable problems at the site of inoculation. We present the case of an otherwise healthy laboratory worker who accidentally self-injected Freund complete adjuvant with heat-killed Mycobacterium tuberculosis into her hand, requiring multiple debridement operations over a prolonged treatment course.

Long-Term Health-Related Quality of Life Outcomes in Digital Replantation versus Revision Amputation.

Background Earlier, digit viability judged the success of digital replantation. Now, utility health-related quality of life (HRQOL) measures can better assess the impact of digital replantation. Methods Overall, 264 digital injury patients were sent a regimen of utility measures: Disabilities of the Arm, Shoulder and Hand (DASH) score, European Quality of Life 5 Dimensions, visual analog scale (VAS), time trade-off (TTO), and standard gamble (SG). Overall, 51 patients responded completely to all of these-36 replantation patients and 15 revision amputation patients. The utility results of these patients were stratified between replantation versus revision amputation; dominant hand replantation versus nondominant hand replantation; and dominant hand revision amputation versus nondominant hand revision amputation. Results The mean VAS score of replant (0.84) and revision amputation (0.75) groups was significantly different (p = 0.05). The mean DASH score of dominant hand replantations (29.72) and nondominant hand replantations (17.97) was significantly different (p = 0.027). The dominant hand revision amputation had higher anxiety levels in comparison to nondominant hand revision amputation (p = 0.027). Patients with two or more digits replanted showed a significant decrease in VAS, TTO, and SG scores in comparison to patients who only had one digit replanted (p = 0.009, 0.001, and 0.001, respectively). Conclusions This study suggests that HRQOL can offer better indices for outcomes of digital replantation. This shows some specific replantation cohorts have a significantly better quality of life when compared with their specific correlating revision amputation cohort. These findings can be employed to further refine indications and contraindications to replantation and help predict the quality of life outcomes.

Arthroscopic Trapeziectomy With Suture Button Suspensionplasty: A Retrospective Review of 153 Cases.

BACKGROUND: Arthroscopic trapeziectomy with suture button suspensionplasty (ATBS) is a relatively new surgical option for the treatment of thumb carpometacarpal (CMC) osteoarthritis. Although ATBS has many potential benefits over alternative surgical treatments for CMC arthritis, little data exist regarding its safety and complication rates. The purpose of this study was to demonstrate that ATBS is associated with a low risk of complications within 1 year of surgery. METHODS: A retrospective review of patients treated with ATBS by one senior hand surgeon over a span of 3 years was performed. RESULTS: A total of 153 cases of ATBS were performed in 136 patients. Ninety-seven cases involved arthroscopic hemitrapeziectomies, and 56 involved arthroscopic complete trapeziectomies. There were 44 males and 92 females with a mean age of 62. Thirty-eight percent of the cases were graded as Eaton stage IV, 46% stage III, and 14% stage II CMC arthritis, while 3 cases (2%) were performed as revisions. Mean follow-up duration was 58 weeks. Mean preoperative key pinch strength of the affected versus the unaffected side was 92% compared with 95% postoperatively. Revision surgery was performed in 9 out of 153 cases (<6%). Of those 9 cases, 5 had additional minor bony debridement with subsequent improvement in pain, 3 had the implant repositioned due to button prominence, and 1 patient presented with osteomyelitis of the first and second metacarpals that was successfully treated with button removal and an antibiotic regimen. CONCLUSIONS: ATBS is a safe, minimally invasive procedure for treatment of symptomatic stages II through IV thumb CMC arthritis.

Schwannoma of the median nerve.

A schwannoma is a benign tumour of Schwann cells that presents as a palpable and painless mass on the volar aspect of the hand and wrist. A 44-year-old, right-handed woman, presented for a volar swelling of her right hand. On examination she had a non-pulsatile mass with no fluctuation at the radiopalmar aspect of the right hand, and a soft mass on the volar aspect of the right palm. There was no pain on palpation. An excisional biopsy specimen showed an encapsulated and extrafascicular tumour that originated in the median nerve fascicules. Histological examination showed a median nerve schwannoma measuring 4.0 x 1.5 x 1.2 cm. Differential diagnosis of hand tumours is divided into three categories: tumours of the soft tissue, bone, and skin. Schwannomas of the median nerve make up 0.1%-0.3% of all hand tumours. Symptoms are caused by an entrapment syndrome resulting from the growing tumour. Pain is the most common complaint of schwannomas distal to the wrist. Imaging studies include computed tomography (CT) and magnetic resonance imaging (MRI). It is difficult to differentiate schwanommas from neurofibromas solely on the basis of an MRI. Neurofibroma grows intraneurally and infiltrates the nerve; it has the potential to require resection of all or part of the nerve, leaving a consequent functional deficit. Tumours of the hand are diagnostically challenging and median nerve shwannomas are rare.

Intravenous heparin use in digital replantation and revascularization: The Quebec Provincial Replantation program experience.

BACKGROUND: No consensus exists among microsurgeons regarding the role of intravenous (IV) heparin in digital replantation/revascularization. The current experience of the Provincial Replantation Center in Quebec was reviewed over a 4-year period. METHODS: An initial retrospective review of all revascularized or reimplanted digits at our Replantation Center from April 2004 to April 2006 was conducted. Then, data of all patients treated at our center from January 08 to September 08 were prospectively collected. The two cohorts were compared with regards to demographics, injury characteristics, postoperative thromboprophylaxis medication as well as complication and success rates. Proportions were compared using χ(2) tests/Fisher's exact tests. Multivariate analysis was conducted with logistic regression. RESULTS: 175 digits were treated from April 2004 to April 2006, including 104 revascularizations and 71 amputations. IV heparin was used in 35.1% of the cases and was associated with a 3.59-fold (95% CI, 1.55-8.31) increase risk of developing a complication compared with cases where heparin was not used (P = 0.001). In 2008, 106 digits were treated. IV heparin was used in 14.6% of the cases and was not significantly associated with a higher complication rate compared with cases where heparin was not used (P = 0.612). Both cohorts' success rates were very similar (P = 0.557). The number of complications decreased from the first period (20.5%) to the second one (12.8%). CONCLUSION: Routine use of IV heparin following digital replantation and revascularization is not warranted. Surgical technique and type of injury remains the most important predictors for success in these complex procedures.

Venous thromboembolism in plastic surgery: incidence, current practice and recommendations.

Venous thromboembolic events (VTEs) are an important concern due to their frequently asymptomatic presentation and significant morbidity and/or mortality. The true incidence of this disease process is unknown as (i) screening procedures and (ii) prophylaxis protocols are frequently lacking in this patient population. The purpose of this study was to identify published thromboprophylactic recommendations established in the plastic surgery literature and to provide a review on thromboembolism and current methods of prophylaxis. A systematic evaluation of all published guidelines for thromboembolism prophylaxis in plastic surgery was conducted. We report on 24 studies in favour of, and three studies against, mechanical and/or pharmacological prophylaxis. Thromboprophylactic recommendations were published by a small randomised trial (grade B, level 2), six retrospective studies (grade C, level IV), two literature reviews (grade C, level V), two surveys (grade C, level V), three narrative reviews (Continuing Medical Education) (grade C, level V) and 10 expert recommendations (grade C, level V). The three publications against prophylaxis were composed of a retrospective study (grade C, level IV) and two case series with no control group (grade C, level V). There is a significant paucity of category A or B evidence favouring thromboprophylaxis in the plastic surgery patient population. There is a need for further research in established thromboprophylaxis guidelines in plastic and reconstructive surgery.

Prevention of surgical site infection and appropriateness of antibiotic prescribing habits in plastic surgery.

OBJECTIVES: The use of antimicrobial prophylaxis against surgical site infection (SSI) is widespread in plastic surgery, while results from prospective randomised controlled trials in guiding antibiotic use are lacking. The purpose of this study was to identify the incidence and risk factors for SSI in plastic surgery, and to evaluate the appropriateness of prophylactic antibiotic prescribing habits in a tertiary university centre. METHODS: A retrospective chart review was conducted over a 6-month period. Co-morbidities, types of procedure, prophylactic antimicrobial administration, SSI rates, and clinical outcomes were evaluated. RESULTS: The incidence of SSI was 9.3% for 335 procedures. The cumulative incidence of SSI for breast surgery (n=80) was 16.3%, with a 78.8% prescription rate. For head and neck procedures (n=68), the incidence of SSI was 10.3%, with 80.9% of patients receiving antibiotic prophylaxis. For hand and upper limb procedures (n=170), 70.6% of patients received antimicrobial prophylaxis, with a 4.7% SSI incidence. According to category A prophylaxis guidelines published in the plastic surgery literature, over prescribing was identified in 27.5% of breast, 61.8% of head and neck, and 19.4% of hand and upper limb procedures. CONCLUSIONS: This is the first study evaluating appropriateness of antimicrobial prophylaxis use by plastic surgeons. Despite widespread use of prophylactic antibiotics, significant SSI rates were still present and frequently responsible for re-hospitalisations and re-interventions. The appropriateness of administration and indications for perioperative prophylactic antibiotic use must be evaluated.

Outcomes in the management of sternal dehiscence by plastic surgery: a ten-year review in one university center.

PURPOSE: Infection rates following median sternotomy vary between 0.2% and 10%. These cases are associated with morbidity and mortality rates between 10% and 25% and 5% and 20%, respectively. The purpose of this study was to evaluate patient outcomes following plastic surgery correction of sternotomy dehiscence (SD). METHODS: All patients operated on for an SD following coronary artery bypass graft surgery (CABG), between 1995 and 2005, with 1 or more flaps, were included. RESULTS: Eighty cases were identified over a 10-year period. The mean age was 64 (+/-9.1) years. Two or more procedures were required in 17.5% of patients, and the mortality rate within 30 days was 12.5%. Significant variability was revealed between the cumulative mortality rates of plastic surgeons, from 0.0% to 50.0%. Multiple associations were identified for poor outcome, including chronic renal insufficiency and early mortality, and obesity with risk of reintervention. CONCLUSION: Although patients who undergo surgical correction of a deep sternal infection usually tolerate their intervention well, the mortality within 30 days remains high. This study has identified several factors explaining morbidity and mortality in this patient population.
