Efficacy of Orthoplastic Management in the Treatment of Traumatic Popliteal Artery Injury.

Popliteal artery injury (PAI) is a challenging condition. Even with appropriate initial treatment and reconstruction of the associated injuries, extensive soft-tissue necrosis may occur, requiring lower leg amputation. There are no reports on the effectiveness of orthoplastic surgery in treating traumatic PAI. However, orthoplastic surgery is also considered very effective in PAI treatment, which requires delicate handling of soft-tissue and blood vessels. This study aimed to examine the treatment outcomes of traumatic PAI at a trauma center with the capacity for orthoplastic management. Patients with PAI who were treated at our institution between August 2013 and December 2021 were included in this study. The surgeons included multiple orthoplastic surgeons with capabilities in vascular repair, bone and ligament reconstruction, and soft-tissue reconstruction. Patient demographics, injury characteristics, degree of ischemia, and treatment were investigated. We also investigated whether soft-tissue reconstruction and lower limb amputation were necessary as outcomes of treatment. Fifteen limbs of 14 patients with PAI met the inclusion criteria. Extensive soft-tissue necrosis was observed in three limbs. Two of these limbs were covered with a free latissimus dorsi flap and could be salvaged. In the remaining limb, lower limb amputation was unavoidable because of unexplained cardiac arrest during the initial surgery, but a fillet flap was used to successfully preserve the knee joint. Orthoplastic management has the potential to improve limb salvage rates and provide good outcomes for the treatment of traumatic PAI.

Overcoming Delayed Diagnosis of Chronic Invasive Fungal Sinusitis in the Immunocompetent Patient: A Case Report

Study Design Case report. Objective To highlight the diagnostic and treatment dilemma associated with chronic invasive fungal sinusitis (CIFS) in the immunocompetent individual. Methods The patient was initially treated for chronic bacterial sinusitis with antibiotic therapy and multiple surgical debridement with no evidence of fungal organisms. Following the completion of the left partial maxillectomy, mucormycosis was finally identified on histopathology, and the appropriate antimicrobial therapy was initiated. During this time, the patient received an interim maxillary obturator for speech and oral function. Following the resolution of CIFS, a computed tomography (CT) of the face was obtained for computer-aided surgical planning for a vascularized fibula flap reconstruction with endosseous dental implants using patient-specific surgical cutting guides and a reconstruction plate. Results Optimal esthetic and functional outcomes were achieved following the placement of the definitive dental prosthesis. The patient remained free of disease and without pain 2 years postoperatively. Conclusions Chronic invasive fungal sinusitis in the immunocompetent patient remains rare; however, delayed diagnosis can lead to inadequate treatment and extensive soft and hard tissue necrosis. Obtaining sufficient tissue sampling is essential for a definitive diagnosis of CIFS. This report demonstrates the challenge in diagnosing CIFS and the importance of the multidisciplinary approach to treat CIFS associated with extensive involvement of the maxilla.

Single stage chest wall soft tissue reconstruction with ipsilateral pectoralis major turnover flap, rhomboid skin flap, and inferior nipple transposition

Extravasation injury is a well-known complication of central venous catheter placement, with potential for extensive soft tissue necrosis. Here, we describe the case of a patient who developed a large right chest well soft tissue defect, due to a chest wall abscess from calcium gluconate infusion via a right internal jugular central venous catheter. After multiple debridements, the chest wall defect was reconstructed with a single stage ipsilateral pectoralis major turnover flap, rhomboid skin flap, and inferior nipple transposition to match the contralateral nipple. There was no further infection, no nipple necrosis, and patient regained full range of motion of the ipsilateral shoulder.

Medial thigh fasciocutaneous flaps for reconstruction of the scrotum following Fournier gangrene: A case report

Fournier's gangrene, a rapidly progressive necrotizing fasciitis of the perineum and external genitalia that leads to extensive soft tissue necrosis, remains a medical‐surgical emergency. The authors present a case of coverage of a scrotal loss of substance with testicular exposure by a medial fasciocutaneous flap of the unilateral thigh after debridement and initial medical treatment of Fournier's gangrene in a 50‐year‐old quadriplegic patient. The clinical examination at 8 months showed an aesthetic and functional result. The trophic‐cutaneous thigh flap that the authors propose for frail, elderly, and neurological subjects with low functional requirements allows coverage of the scrotal region with relatively thick skin, color, and texture close to those of the scrotum. It also offers technical simplicity, moderate scarring, and functional remnants at the price of less morbidity.

Drug-induced cutaneous vasculitis and anticoagulant-related cutaneous adverse reactions: insights in pathogenesis, clinical presentation, and treatment

Drug-induced vasculitis and anticoagulant-related skin reactions are commonly encountered in the inpatient and outpatient settings. The spectrum of clinical presentation is broad and ranges from focal, skin-limited disease, to more extensive cutaneous and soft tissue necrosis, to potentially fatal systemic involvement. The prompt recognition of these adverse events can have a significant impact on patient morbidity and mortality. We highlight the key features of the clinical presentation with an emphasis on primary lesion morphology, distribution, and epidemiology of purpuric drug reactions. The proposed pathophysiology, histologic findings, and therapeutic interventions of these potentially life-threatening diseases are discussed.

Auditing the Routine Microbiological Examination of Pus Swabs From Uncomplicated Perianal Abscesses: Clinical Necessity or Old Habit?

BackgroundObtaining pus swabs from perianal abscesses after incision and drainage for subsequent microbiological analysis is traditionally performed by general surgeons. Our aim is to assess the current practice in our institution, emphasizing on whether pus swabs were sent or not, as well as to identify any associations between the revealed microbiology and the occurrence of immediate post-operative complications and re-admission rates with fistula-in-ano up to 12 months post the emergency drainage. Finally, we aimed to identify if the any members of the surgical team reviewed at any stage post-operatively the results of the microbiological examination of the obtained pus swabs and if that resulted in changes of the patient management.MethodsWe reviewed the operative findings and perioperative antimicrobial management of all patients within our institution that required surgical treatment of perianal abscesses over a 6-week period and re-assessed them after 12 months from the performed drainage, with respect to re-admission and identification of occurred fistula-in-ano.ResultsA total of 24 patients met our inclusion criteria. Pus swabs were sent in 66.7% of cases and only a third of the requested microbiology reports were reviewed by a part of the surgical team. All patients were discharged prior to the release of the microbiology results with no subsequent change in the management plan. We did not find any consistent association between the microbiology results and re-admission with perianal abscess, with or without fistula-in-ano.ConclusionsWe do not recommend routine use of pus swabs when draining perianal abscesses unless clinical concerns arise, including recurrent perianal sepsis, immuno-compromised status or extensive soft tissue necrosis, especially when these features are associated with systemic sepsis.

ISCHEMIC SKIN NECROSIS SECONDARY TO THE USE OF TERLIPRESSIN

We present the case of a 45-year-old male with alcoholic liver cirrhosis Child-Pugh C and chronic left lower limb lymphedema, hospitalized because of ascites and renal impairment (Cr 2.33 mg/dl). He received intravenous albumin and terlipressin (1 mg every 4h) for suspected hepatorenal syndrome. After 48 hours, purpuric skin lesions appeared on both lower extremities, scrotum and umbilical hernia. Renal function improved (Cr 0.49 mg/dl). Nevertheless, terlipressin was discontinued as the skin lesions worsened due to epidermal detachment, and oral sildenafil was administered at 50 mg twice per day. The left lower limb was severely affected with extensive skin and soft tissue necrosis, which led to supracondylar amputation. All the other lesions had a satisfactory evolution, with reepithelialization of the damaged areas.

Calciphylaxis — pathogenesis and clinical picture

Calciphylaxis, also known as calcific uremic arteriolopathy (CUA), is a rare vascular disease caused by deposition of calcium salts in vessel walls, accompanied by coagulation disorders, which leads to extensive skin ulceration and soft tissue necrosis. Typical cases of calciphylaxis are usually described in patients with renal failure, though it is currently known that approx. 1/10th of all cases stem from other causes, including systemic inflammation, metabolic disorders and endocrine disorders. This article shows an overview of the most important pathophysiological phenomena which accompany calciphylaxis, characterizes the clinical picture of the disease and presents available approaches to therapeutic management.

Analysis of prognostic factors affecting poor outcomes in 41 cases of Fournier gangrene.

PurposeWe present our experience involving the management of this disease, identifying prognostic factors affecting treatment outcomes.MethodsThe patients treated for Fournier gangrene at our institution were retrospectively reviewed. Data collected included demographics, extent of soft tissue necrosis, predisposing factors, etiological factors, laboratory values, and treatment outcomes. The severity index and score were calculated. Multivariate regression analysis was used to determine the association between potential predictors and clinical outcomes.ResultsA total of 41 patients (male:female = 33:8) were studied. The mean age was 54.4 years (range, 24–79 years). The most common predisposing factor was diabetes mellitus (n = 19, 46.3%). Sixteen patients (39.0%) were current smokers. Seven patients had chronic kidney disease. The most frequent etiology was urogenital lesion (41.5%). The mortality rate was 22.0% (n = 9). Multivariate regression analyses showed that extension of necrosis beyond perineal/inguinal area and pre-existing chronic kidney disease were significant and independent predictors of mortality. Extension of necrosis beyond perineal/inguinal area was a significant predictor of increased duration in the intensive care unit and hospital stay. In addition, pre-existing chronic kidney disease was a significant predictor of flap reconstruction in the wound.ConclusionFournier gangrene with extensive soft tissue necrosis and pre-existing chronic kidney disease was associated with poor prognosis and complexity of patient management. Early recognition of dissemination and premorbid renal function is essential to reduce mortality and establish a management plan for this disease.

Cadaver-based Necrotizing Fasciitis Model for Medical Training.

Necrotizing fasciitis is a devastating infectious disease process that is characterized by extensive soft tissue necrosis along deep fascial planes, systemic toxicity, and high mortality. Ultrasound imaging is a rapid and non-invasive tool that can be used to help make the diagnosis of necrotizing fasciitis by identifying several distinctive sonographic findings. The purpose of this study is to describe the construction of a realistic diagnostic training model for necrotizing fasciitis using fresh frozen cadavers and common, affordable materials.Presently, fresh non-embalmed cadavers have been used at medical institutions for various educational sessions including cadaver-based ultrasound training sessions. Details for the preparation and construction of a necrotizing fasciitis cadaver model are presented here. This paper shows that the images obtained from the cadaver model closely imitate the ultrasound appearance of fluid and gas seen in actual clinical cases of necrotizing fasciitis.Therefore, it can be concluded that this cadaver-based model produces high-quality sonographic images that simulate those found in true cases of necrotizing fasciitis and is ideal for demonstrating the sonographic findings of necrotizing fasciitis.

Extensive Soft Tissue Necrosis Due to Extravasation of Computed Tomography Contrast Medium

Combined Vascular and Orthopaedic Approach for a Pseudotumor Causing Deep Vein Thrombosis after Metal-on-Metal Hip Resurfacing Arthroplasty.

Introduction. Metal-on-metal (MoM) hip resurfacings have been associated with a variety of complications resulting from adverse reaction to metal debris. Pseudotumors have rarely been reported to cause deep venous thrombosis (DVT). Study Design. A case report and a review of the literature. Case Presentation. A 75-year-old female who had left metal-on-metal hip resurfacing 6 years ago presented with left groin pain associated with unilateral lower limb edema and swelling. By duplex and MRI studies, our patient had an extensive soft tissue necrosis associated with a large pelvic mass causing extensive DVT of the lower limb secondary to mechanical compression of the left iliac vein. Results. Our case was initially treated for DVT followed by dual surgical approach. The pseudotumor was excised through a separate iliofemoral approach and revision of the hip implant was undertaken through a posterior approach in the same setting. An inferior vena cava (IVC) filter was inserted to minimise the perioperative risks of handling the iliac veins. Conclusion. A combined approach with vascular surgeons is required. Combined resection of the pseudotumor and revision of the metal bearing surfaces is essential, in order to achieve a good surgical outcome in this rare complication.

Implant based differences in adverse local tissue reaction in failed total hip arthroplasties: a morphological and immunohistochemical study.

BackgroundAdverse local tissue reaction (ALTR) is characterized by periprosthetic soft tissue inflammation composed of a mixed inflammatory cell infiltrate, extensive soft tissue necrosis, and vascular changes. Multiple hip implant classes have been reported to result in ALTR, and clinical differences may represent variation in the soft tissue response at the cellular and tissue levels. The purpose of this study was to describe similarities and differences in periprosthetic tissue structure, organization, and cellular composition by conventional histology and immunohistochemistry in ALTR resulting from two common total hip arthroplasty (THA) implant classes.MethodsConsecutive patients presenting with ALTR from two major hip implant classes (N = 54 patients with Dual-Modular Neck implant; N = 14 patients with Metal-on-Metal implant) were identified from our prospective Osteolysis Tissue Database and Repository. Clinical characteristics including age, sex, BMI, length of implantation, and serum metal ion levels were recorded. Retrieved synovial tissue morphology was graded using light microscopy and cellular composition was assessed using immunohistochemistry.ResultsLength of implantation was shorter in the DMN group versus MoM THA group (21.3 [8.4] months versus 43.6 [13.8] months respectively; p < 0.005) suggesting differences in implant performance. Morphologic examination revealed a common spectrum of neo-synovial proliferation and necrosis in both groups. Macrophages were more commonly present in diffuse sheets (Grade 3) in the MoM relative to DMN group (p = 0.016). Perivascular lymphocytes with germinal centers (Grade 4) were more common in the DMN group, which trended towards significance (p = 0.066). Qualitative differences in corrosion product morphology were seen between the two groups. Immunohistochemistry showed features of a CD4 and GATA-3 rich lymphocyte reaction in both implants, with increased ratios of perivascular T-cell relative to B-cell markers in the DMN relative to the MoM group (p = 0.032).ConclusionOur results demonstrate that both implant classes display common features of neo-synovial proliferation and necrosis with a CD4 and GATA-3 rich inflammatory infiltrate. Qualitative differences in corrosion product appearance, macrophage morphology, and lymphocyte distributions were seen between the two implant types. Our data suggests that ALTR represents a histological spectrum with implant-based features.

Infections Caused by Acinetobacter baumannii in Recipients of Hematopoietic Stem Cell Transplantation.

Acinetobacter baumannii (A. baumannii) is a Gram-negative, strictly aerobic, non-fermentative coccobacillus, which is widely distributed in nature. Recently, it has emerged as a major cause of health care-associated infections (HCAIs) in addition to its capacity to cause community-acquired infections. Risk factors for A. baumannii infections and bacteremia in recipients of hematopoietic stem cell transplantation include: severe underlying illness such as hematological malignancy, prolonged use of broad-spectrum antibiotics, invasive instrumentation such as central venous catheters or endotracheal intubation, colonization of respiratory, gastrointestinal, or urinary tracts in addition to severe immunosuppression caused by using corticosteroids for treating graft versus host disease. The organism causes a wide spectrum of clinical manifestations, but serious complications such as bacteremia, septic shock, ventilator-associated pneumonia, extensive soft tissue necrosis, and rapidly progressive systemic infections that ultimately lead to multi-organ failure and death are prone to occur in severely immunocompromised hosts. The organism is usually resistant to many antimicrobials including penicillins, cephalosporins, trimethoprim–sulfamethoxazole, almost all fluoroquinolones, and most of the aminoglycosides. The recently increasing resistance to carbapenems, colistin, and polymyxins is alarming. Additionally, there are geographic variations in the resistance patterns and several globally and regionally resistant strains have already been described. Successful management of A. baumannii infections depends upon appropriate utilization of antibiotics and strict application of preventive and infection control measures. In uncomplicated infections, the use of a single active beta-lactam may be justified, while definitive treatment of complicated infections in critically ill individuals may require drug combinations such as colistin and rifampicin or colistin and carbapenem. Mortality rates in patients having bacteremia or septic shock may reach 70%. Good prognosis is associated with presence of local infection, absence of multidrug resistant strain, and presence of uncomplicated infection while poor outcome is associated with severe underlying medical illness, bacteremia, septic shock, multi-organ failure, HCAIs, admission to intensive care facilities for higher levels of care, and culture of certain aggressive genotypes of A. baumannii.

Inflammatory Pseudotumor Causing Deep Vein Thrombosis After Metal-On-Metal Hip Resurfacing Arthroplasty

Metal-on-metal hip resurfacings have recently been associated with a variety of complications resulting from adverse reaction to metal debris. We report a case of extensive soft tissue necrosis associated with a huge pelvic mass causing extensive deep vein thrombosis of the lower limb secondary to mechanical compression of the iliac vein. This is a rare and unusual cause of deep vein thrombosis after metal-on-metal hip resurfacing arthroplasty.

Canine Streptococcal Toxic Shock Syndrome associated with Necrotizing Fasciitis: An Overview

Canine Toxic Shock Syndrome (CSTSS) is a serious often fatal disease syndrome seen in dogs caused as a result of an infection caused by gram positive cocci of the family Streptococci. The main bacterium involved in the etiology of Canine Streptococcal Toxic Shock Syndrome is Streptoccoccus canis, which was discovered by Deveriese in 1986 and implicated as a cause of this disease syndrome in 1996 by Miller and Prescott. The clinical findings in this syndrome are very much similar to those seen in the infamous 'Toxic Shock 'caused by staphylococcal toxins in humans, especially females. Like in humans, the reason for emergence/reemergence of Canine Streptococcal Toxic Shock Syndrome (CSTSS) is unclear and very little is known about its transmission and prevention. The disease is characterized by multi systemic organ failure and a shock like condition in seemingly healthy dog often following an injury. In absence of proper and prompt diagnosis and subsequent treatment by injectable antibiotics and aggressive shock therapy, dog often succumbs to the disease within a few hours. The dog may have some rigidity and muscle spasms or convulsions and a deep unproductive cough followed by haemorrhage from nasal and mouth along with melena. On necropsy, these dogs show severe edema of the gastrointestinal tract, congestion of multiple organs, severe pulmonary congestion and evidence of thrombo embolism. Necrotizing fasciitis is a localized form of streptococcal infection seen as extensive soft tissue sloughing and necrosis along the fascial planes. No vaccination is available so avoidance of the probable causal factors mainly participation in community events, estrus, change of environment and shipping is the only way to keep pet dogs away from this disease.

Index of Suspicion in the Nursery

Twins are born at 37-5/7 weeks gestation to a 41-year-old G4P2 woman who had unremarkable serology results. The delivery is via cesarean section because of a nonreassuring fetal heart rate. Twin B appears to be acrocyanotic and initially requires positive-pressure ventilation for 30 seconds before being able to maintain her oxygen saturation on her own. Apgar scores are 7 and 8 at 1 and 5 minutes, respectively. She also appears to be “jittery,” and her screening glucose concentration is 24 mg/dL (1.3 mmol/L). She consumes 20 mL of infant formula and a 10% dextrose (D10) infusion is begun at a rate of 60 mL/kg per day. Three hours after birth, a follow-up glucose evaluation measures 30 mg/dL (1.7 mmol/L), prompting administration of a 4-mL/kg bolus of D10 over 20 minutes and increase of the maintenance infusion rate to 100 mL/kg per day. Six hours after birth, glucose measures 80 mg/dL (4.4 mmol/L), and the infusion rate is decreased to 60 mL/kg per day. She is transferred to a hospital that has a neonatal intensive care unit (NICU) for close monitoring. On transfer, the oxygen saturation dips into the upper 80s/lower 90s, and nasal cannula administration of oxygen is initiated. Furthermore, during transfer (8 to 9 hours after birth), the blood glucose value is 44 mg/dL (2.4 mmol/l), so the D10 infusion rate is increased back to 100 mL/kg per day. On arrival at the second hospital, her oxygen saturation is about 85% and glucose is 50 mg/dL (2.8 mmol/L). In the NICU, she receives noninvasive respiratory support as well as 15% dextrose (D15) at a rate of 70 mL/kg per day. Twin A remains stable and continues to receive routine newborn care in the newborn nursery of the first hospital. Two days after birth, twin B continues to have glucose …

Extensive muscle necrosis and infection following treatment of a lower extremity vascular malformation with Sotradecol and absolute ethanol

Venous malformations are a subset of low-flow vascular malformations. These are usually present at birth and grow commensurate with the child. The treatment of low-flow vascular malformations has been studied extensively. Many interventions have been devised to benefit this patient population in regard to the pain, ulcerations, infections, cosmetic concerns, and overall bulk associated with these malformations. Treatment can begin with compression garments. Another treatment is sclerotherapy. This can be done as a stand-alone treatment or as an adjunct to surgical excision. Percutaneous sclerosis of venous malformations has an efficacy of between 74 and 90% in relieving symptoms. We present a case of percutaneous sclerotherapy with Sotradecol and ethanol into an extensive lower extremity venous malformation in the setting of orthopedic megaprosthesis. We feel that this led to extensive soft tissue necrosis and infection of the limb and created a precipitous situation.
