Marjolin’s ulcer of the forearm from 30-year-neglection of external fixator

BackgroundMarjolin’s ulcers are a rare form of malignancy that present at regions exposed to chronic infection. They present with a clinical triad of nodularity, induration, and ulceration greater than 3 months.Case reportWe present herein, an extremely rare case of Marjolin’s ulcer of the forearm, secondary to osteomyelitis, resulting from a 30-year neglection of external fixator used to treat a war injury of the forearm.DiscussionMarjolin’s ulcers are classically encountered in lower extremities at sites of burns, trauma or complicated wounds. In the upper extremity however, they are seldom mentioned in literature. The presence of risk factors raise the suspicion of the disease.ConclusionMarjolin’s ulcer is rare sequelae of chronic wound infection. Patients often present after a latency period with exacerbated pain, discharge, and exophytic mass. This disease should be suspected in every case of chronic ulcer, where histological studies of the lesion must be conducted to exclude or confirm the diagnosis.     

Marjolin’s Ulcers in sub-Saharan Africa

Background  

Cutaneous malignancies are considered rare among Africans. Trauma, its sequelae, and other chronic non-healing wounds are known to predispose to malignant degeneration. Not much is known of the demographics of Marjolin’s ulcers in sub-Saharan Africa.     

One center’s experience developing a burn outpatient registry

IntroductionRecent advances in burn care have resulted in the transition of care from inpatient to outpatient. There is a growing appreciation that with improved survival, meaningful markers of quality need to include recovery of form, function, and reconstruction. Capture of the data describing care delivered in the outpatient setting is being missed.MethodsDevelopment of our outpatient database included providers, registrar, program manager, and outpatient nursing staff. Data points were included if they described the population, and epidemiology of our patients, were useful for programmatic changes and improvements as well as anticipated research focus areas.ResultsThe database platform chosen was Midas+™ because it was in use by hospital quality and integrated with the electronic medical record. Fields were customized based on changing program needs and are updated for new programs or outcomes measures. Reports can be easily built and both outpatients and inpatients are included. This allows for longitudinal tracking of burn patients. Ongoing additions to original data points include variables to track outcomes related to laser therapy for scar management, time to custom garment donning, and to track functional outcomes. Epidemiologic data collected is used to target high-risk populations for prevention and outreach efforts. Outcome data is used for evaluation of programs and care.ConclusionsHigh quality databases serve to measure effectiveness of care and offer insight for areas of improvement. There is a clear need for inclusion of outpatient activity in the National Burn Registry (NBR).     

Malignant melanoma in a skin graft: burn scar neoplasm or a transferred melanoma?

Malignant melanomas (MM) arising in burn scars are rare with 16 cases previously reported. Malignant melanomas arising on skin grafts are even more rare with only two cases reported. We present the case of MM arising on a burned area that had been previously grafted with a split thickness skin graft. A 19-year-old patient sustained 20% burns in a road traffic accident. The burned areas were debrided and skin grafted. Six months later, the patient developed MM on the left calf (an area that was burned and grafted). The tumour was excised with wide margins. Six months following the excision of the MM, the patient started to develop multiple dysplastic naevi in the skin grafted burned areas. In the present case, the main question to be answered is whether the MM arose from the donor or the recipient site of the split thickness skin graft. After thorough discussion of the two options and reviewing the literature, the authors believe that the MM and the atypical naevi were transferred to the recipient site with the skin graft. Therefore, it is suggested that in the process of harvesting skin grafts, any pre-existing naevi should be avoided or removed, and if this is not feasible, should be recorded in detail in the operation notes. Also, patients at discharge should be advised that any change in the appearance of the grafts or any new lesions in the engrafted areas should be reported to their physicians.     

Patterns and predictors of burn scar outcome in the first 12 months after burn: The patient’s perspective

ObjectiveThis study aimed to provide insight into the patterns and factors that predict burn scar outcomes at 3, 6 and 12 months after burn.MethodsThe Patient and Observer Scar Assessment Scale (POSAS) was used to assess the scar formation of each patient. Structural equation modelling was used. The predictor variables used in this study were sex, three age categories, TBSA, depth of the wound and cause of the burn.ResultsThe POSAS patient total and individual item scores demonstrated a statistically significant decrease in the first 12 months after burn, except for the relief item. Male patients had a lower total and items scores (better scar quality) for pain and pruritus compared with female patients. Full thickness burns had a higher scores for pruritus, pliability, thickness and relief compared to the partial-thickness burns. Ages younger than 5 years, higher TBSA values and flame burns were predictors of various POSAS items at 3 and 6 months after burn.ConclusionThe POSAS patient total and individual item scores demonstrated a statistically significant improvement in the scar quality in the first 12 months after burn, except for the relief. Sex, age, depth of the wound, the percentage of TBSA and flame burns were predictors of various POSAS patient items at 3, 6 and 12 months after burn.     

Risk of graft fracture after dorso-ventral thoraco-lumbar spondylodesis: is there a correlation with graft size?

Study design

Retrospective clinical study in patients with dorso-ventral thoraco-lumbar spondylodesis.

Objective

To investigate whether the ratio between graft cross sectional area and the surface area of the adjacent endplates has any effect on the midterm stability of the spondylodesis.

Summary of background data

Dorso-ventral spondylodesis in the region of the thoraco-lumbar spine is one of the most frequent operations in orthopaedic surgery. Anterior stabilization with autologous iliac crest graft currently is a standard approach in many hospitals. Although numerous recommendations are given how to perform this technique, no clinical advice is available with regard to minimum graft size.

Methods

Sixty-four-slice CT-scans were obtained from 82 patients 4–12 months after posterior spondylodesis with anterior implantation of iliac crest graft and stabilization with an internal fixator. The scans were analyzed using image analysis software. First, the cross sectional area of the graft was calculated and then the surface area of the adjacent endplates. The ratio between graft cross sectional area and endplate surface area was then calculated from these two values. The grafts were then evaluated in sagittal reconstruction for signs of fracture.

Results

The probability for graft fracture in autologous tricortical grafts was >0.1% (p < 0.001) if the graft cross sectional area exceeded 23.9% of the surface area of the adjacent endplates. Patients with lower ratio values had a higher fracture risk and below a value of 10% all grafts fractured.

Conclusion

The relationship between graft cross sectional area and adjacent endplate area has an important effect on graft midterm stability in ventral spondylodesis of the thoraco-lumbar spine. In our opinion, the risk of graft fractures in dorso-ventral spondylodesis can be reduced by implantation of an appropriately sized graft without any additional procedures or instrumentation.     

Donor’s site evaluation after restoration with autografts or synthetic plugs in rabbits

AIM: To investigate donor site's area histological and immunohistochemical knee cartilage appearances after resurfacing iatrogenic defects with biosynthetic plugs orautografts. METHODS: Thirty New Zealand White rabbits were used in this study. A full-thickness cylindrical defect of 4.5 mm(diameter) × 7 mm(depth) was created with a hand drill in the femoral groove of every animal. In Group A(n = 10) the defect of the donor site was re-paired with a biosynthetic osteochondral plug, in Group B(n = 10) with an osteochondral autograft, while in Group C(control group of 10) rabbits were left untreated. RESULTS: Twenty-four weeks postoperatively, smooth articular cartilage was found macroscopically in some trocleas' surfaces; in all others, an articular surface with discontinuities was observed. Twenty-eight out of 30 animals were found with predominantly viable chondrocytes leaving the remaining two-which were found only in the control group- with partially viable chondrocytes. However, histology revealed many statistical differences between the groups as far as the International Cartilage Repair Society(ICRS) categories are concerned. Immunofluoresence also revealed the presence of collagen Ⅱ in all specimens of Group B, whereas in Group A collagen Ⅱ was found in less specimens. In Group C collagen Ⅱwas not found. CONCLUSION: The matrix, cell distribution, subchondral bone and cartilage mineralization ICRS categories showed statistically differences between the three groups. Group A was second, while group B received the best scores; the control group got the worst ICRS scores in these categories. So, the donor site area, when repairing osteochondral lesions with autografting systems, is better amended with osteochondral autograft rather than bone graft substitute implant.     

Does pretransplant soluble CD30 serum concentration affect deceased-donor kidney graft function 3 years after transplantation?

Elevated serum concentrations of soluble CD30 molecule (sCD30) have been related to acute cellular rejection and poor graft outcomes in kidney transplantation. This historical cohort study investigated the association of pretransplant sCD30 serum concentrations with kidney graft function expressed as estimated glomerular filtration rate (GFR) at 3 years after transplantation. Pretransplant sera from 176 adult deceased-donor kidney graft recipients were tested for sCD30 content using a commercially available automated enzyme-linked immunosorbent assay. The immunosuppression consisted of induction therapy with monoclonal anti-CD25 antibodies and a maintenance regimen of cyclosporine (CsA)-based therapy. GFR was estimated (eGFR) by the four-variable Modification of Diet in Renal Disease (MDRD) Study equation. According to the distribution of pretransplant sCD30 levels (median 66.7 U/mL; interquartile range, 46.6 to 98.6 U/mL), a concentration of 66 U/mL or higher was defined as high (n = 89) and below 66 U/mL as low (n = 87). Three years after transplantation, eGFR was not significantly different among recipients in high versus low sCD30 groups (69 +/- 23 mL/min/1.73m2 vs 66 +/- 21 mL/min/1.73m2; P = .327) and there was no correlation between eGFR and pretransplant sCD30 levels (r2 = 0.001; P = .73). Upon multivariate regression analysis, donor age, recipient body mass index at transplantation, and acute rejection episodes were independent variables affecting eGFR at 3 years after transplantation. This study showed that pretransplant sCD30 serum concentrations were not associated with deceased-donor kidney graft function at 3 years after transplantation. The immunosuppression with anti-CD25 antibodies and a triple CsA-based maintenance regimen could possibly be decisive for our findings.     

Choledocholithiasis after Bariatric Surgery—More than a Stone’s Throw to Reach?

Background

Gallstone disease is common after bariatric surgery, and patients with bile duct stones in this cohort can be difficult to treat, due to the altered anatomy. This review aims to analyse the various management options available for choledocholithiasis in post-bariatric surgery patients.

Methods

A literature search of PubMed, Medline and Cochrane library databases was carried out for studies on this subject, between January 1970 and March 2017. After initial screening and further full text review, suitable studies were identified after applying the inclusion criteria.

Results

Twenty-nine studies were identified and analysed. Overtube-assisted endoscopy appears to be a popular technique, and 10 studies employing this technique were identified. Though there are minor variations between the three different types of overtube endoscopy, the success rate for ERCP with this approach is between 60 and 70%. Studies using a combination of radiological and endoscopic techniques report a success rate of 60–70%, though the endoscopic ultrasound-guided technique has been reported to have higher success rates (90–100%). Surgery-assisted ERCP also appears to be widely reported and has a consistently high ERCP success rate (80–100%), with an added advantage of the option to perform a concomitant cholecystectomy. There are very few reports on using surgery as the sole option in this scenario.

Conclusion

Both overtube-assisted endoscopy and laparoscopy-assisted ERCP appear to be safe, with good success rates. The other methods may be suitable for selected patients and centres with specific interest in such techniques.

     

Impact of the affordable care act’s medicaid expansion on burn outcomes and disposition

BackgroundWe aimed to analyze the impact of the Affordable Care Act’s Medicaid Expansion on clinical outcomes and patient disposition after burn injury. We hypothesized that increased insurance coverage results in improved outcomes and higher rates of discharge to inpatient rehabilitation.MethodsWe reviewed the University of Washington Regional Burn Center registry data for patients admitted from 2011 to 2018. Patients were grouped into two categories: before (2011–2013) and after (2015?2018) Medicaid expansion; we excluded 2014 data to serve as a washout period. Outcomes assessed included length of hospital stay, patient disposition, and mortality. Multivariable logistic and linear regression models with covariates for sex, age, burn size, ethnicity ethnicity, distance from burn center, etiology of burn, and presence of inhalation injury were used to determine the impact of Medicaid expansion on outcomes.ResultsRates of uninsured patients decreased while Medicaid coverage increased. Despite increased median burn size after Medicaid expansion, inpatient mortality rates did not change, but average acute care length of stay increased. More patients were discharged to rehabilitation centers.ConclusionsOur study corroborates prior findings of increased insurance coverage since Medicaid expansion. Increased insurance coverage is associated with higher rates of discharge to inpatient rehabilitation programs after burn injury.     

Esophageal adenocarcinoma after Nissen’s fundoplication for Barrett’s esophagus: report of a case

It remains unclear whether surgical treatment of gastro-esophageal reflux disease (GERD) and Barrett’s esophagus (BE) decreases the long-term risk of lower esophagus malignancy; yet, proposed reductions in Barrett’s epithelial transformation have been used as a rationale for antireflux surgery. We report the case of a 63-year-old woman with a 40-year history of GERD, whose symptoms returned after a Nissen fundoplication. A gastroscopy done 3 years later revealed BE. Despite close surveillance, adenocarcinoma of the lower esophagus was diagnosed 8 years after the original surgery. Thus far, there is insufficient evidence to convince practitioners that surgery should be the first line of treatment to prevent malignant change in BE. Further well-standardized, prospective trials are required. Our case demonstrates that antireflux surgery in a patient with GERD and BE cannot be relied upon to prevent adenocarcinoma.     

Multiple graft injury due to migrated nonbroken sternal wires 2 years after cardiac surgery

The migration of sternal wires into vital structures is a rare but potentially life-threatening complication and associated with infection in some cases. While a few cases have been reported the sternal wires were broken in those cases. To our knowledge, this is the first report of multiple, nonbroken, migrated sternal wires stabbing vascular grafts.     

Women’s recovery,negotiation of appearance,and social reintegration following a burn

The gendered nature of postburn coping has received scant research attention in South Africa, a country that has a high rate of burns with significant concentrations among women. In this study, narratives that emerged from in-depth interviews with seven women were examined. The narratives emphasized essential needs of these burn survivors for personal support, the complexities of negotiating intimate relationships, struggles with the humiliation from family and friends, in some instances strained relationships with children, the support found through religious beliefs and institutions, and often frustratingly slow psychological acceptance of scars. These difficulties faced by women survivors of burns have highlighted the need to include religion/spirituality, intimate male partners, and women’s children into the psychological recovery process, in an attempt to assist women’s journey to psychological and emotional healing after burn.
