Complications in surgical management of calcaneal fractures with anatomical plates

<p class="abstract"><span lang="EN-US">Calcaneal fractures, irrespective of their types, are treated non-operatively, one of the reasons being fear of complications. But conservatively managed fractures can result in equally problematic complications. Incidence of subtalar arthritis in such cases is reported to be 16.9% compared 3.3% in cases treated surgically. With surgical treatment aimed at achieving anatomical joint reduction, regaining calcaneal height, its length and width, successful attempts at curtailing the long-term complications can be made. This was a prospective study of 20 cases of calcaneal fractures, admitted to MNR Medical College and Hospital, Sangareddy from August 2020 to September 2021 were treated with ORIF with non-locking anatomical calcaneal plates using Fernandez’s approach, without use of bone graft. Essex Lopresti and Sander’s classification were used. Intra-operative assessment of reduction and articular surface reconstruction was done under fluoroscopic guidance. Regular follow up was done for assessment of fracture union and complications, assessment of late collapse. Among the 20 cases, 73% were men and 27% women. On typing the fractures based on Essex-Lopresti classification, intra-articular tongue type constituted 13% and 87% were of joint depression. Near normal anatomical reduction was obtained in all cases except in one where it was difficult due to comminution noted during surgery. 2 cases developed superficial skin necrosis at the surgical site, 1 case of deep infection and abscess formation and 3 cases of subtalar arthritis. This study showed that the incidence of long-term complications can probably be minimized by restoring the altered anatomy through surgical means; hence we advocate surgical management and accurate anatomical reduction in cases of displaced and comminuted calcaneal fractures with proper surgical principles. </span></p>

Rapidly Spreading Deep Dissecting Hematoma Occurring One Month After A Minor Trauma: A Case Report.

Background: Deep dissecting hematoma (DDH) is a rapidly extending blood collection that splits the hypodermis from muscle fascia, constituting a medical surgical emergency. The natural history of this condition includes trauma (even minor physical injury) shortly before onset of the lesion, occurring in a patient with advanced dermatoporosis. A delay of several weeks between the appearance of a superficial haematoma following a minor trauma and its sudden decompensation into a rapidly spreading DDH has been scarcely mentioned in the medical literature. Case presentation: We report the admission of a 70-year-old woman under anticoagulation to the emergency department of our hospital for the sudden appearance of a rapidly evolving hematoma one month after a negligible trauma to the right leg. A complete skin examination revealed clinical signs (spontaneous superficial skin haematomas, lacerations, wrinkles, stellate pseudo-scars) of advanced dermatoporosis, especially on the forearms. The initial biological testing disclosed an International Normalized Ratio of 3.15. The clinical aspect of the haematoma, its rapid extension and the cutaneous signs of dermatoporosis on the forearms allowed the diagnosis of DDH. Bedside ultrasound examination was used to eliminate differential or additional diagnoses and to assess the main features of the hematoma (dimensions, existence of blood supply). Due the extent of the lesion and the risk of extended skin necrosis, surgical debridement and hematoma drainage were performed. The operative report confirmed the diagnosis of DDH. Wound healing was obtained spontaneously after three months. Conclusion: DDH is the most serious complication of dermatoporosis. Given its rapid horizontal extension and the risk of skin necrosis it induces, DDH is a medical-surgical emergency and must be diagnosed early. This observation emphasises that in patients with severe dermatoporosis, on the occasion of a Vitamin K Antagonist overdose, a limb-threatening DDH can develop suddenly, even several weeks after a minor impact.

Safety and Efficacy of Collagen-Based Biological Dressings in the Management of Chronic Superficial Skin Wounds in Non-Complex Trauma: A Post-Marketing Surveillance Study

Biological dressings such as collagen and hyaluronic acid represent the main advanced tools that plastic surgeons, dermatologists and vulnologists use today to treat chronic wounds or ulcers that do not tend to heal. These types of dressings are important because they create a moist and physiological interface at the wound level, are of natural origin, easy to use, hypo-allergenic, economical and do not create discomfort for the patient during dressing changes. We treated 128 patients (divided into four groups based on type of dressing) with non-complex superficial chronic wounds in comparison with a traditional dressing (fitostimoline gauze or polyurethane foam). We analyzed wound characteristics, healing time, and operator and patient satisfaction. A significantly higher recovery rate was observed in the “Collagen-coated plates” treatment group compared to Standard Treatment. Additionally, a significantly higher probability of recovery was observed compared to the alternative two experimental devices (Collagen-coated plates + HA and Collagen-based spray). However, the main limitation of the randomization of this study is the presence in the “Collagen-based spray” group of localized wounds, mainly in the fingers and hand. No side effects were reported in relation to the procedures or the experimental products. Collagen may be considered as a valuable therapeutic tool in non-complex chronic wounds by virtue of its low immunogenicity, flexibility and applicability in biocompatible scaffolds, and represents driving force toward enhanced wound care.

Genetic Diversity of Staphylococcus aureus Strains from a Tertiary Care Hospital in Rawalpindi, Pakistan

Staphylococcus aureus is an important healthcare-associated bacterium that causes a multitude of infections in humans such as superficial skin and soft tissue infections, necrotizing pneumonia, foodborne illnesses and postsurgical infections. Treatment of S. aureus infections has become more complicated due to the emergence of Methicillin-Resistant Staphylococcus aureus (MRSA), some of which are multidrug resistant. The present study aimed to characterize S. aureus isolates from a tertiary care hospital in the Rawalpindi district of Pakistan. Staphylococci were isolated from 300 clinical samples collected from January 2018 to January 2019 and S. aureus isolates were tested for antimicrobial susceptibility and analyzed using Pulsed-Field Gel Electrophoresis (PFGE), Multi-Locus Sequence Typing (MLST), staphylococcal cassette chromosome mec (SCCmec) and spa typing. Approximately 25.3% (76/300) of the clinical samples were positive for S. aureus; of those, 88.2% (67/76) were mecA+ (MRSA). In addition to the β-lactam antibiotics, high levels of resistance were also found to the fluoroquinolones (ciprofloxacin, gatifloxacin and levofloxacin (73.7% each)). Of the 23 different spa types identified, the majority of isolates belonged to spa type t632 and t657 (9/66; 13.6% each spa type). ST772-t657 (Bengal Bay clone) was the most commonly identified clone in this study although other clones circulating around different regions of the world were also found indicating the diversity in MRSA isolates from this area of Pakistan. This study emphasizes the need to monitor MRSA in the clinical setting for improved infection control and treatment options.

Donor Site Morbidity in Unilateral and Bilateral Transverse Musculocutaneous Gracilis (TMG) Flap Breast Reconstruction: Sensation, Function, Aesthesis and Patient-Reported Outcomes

The transverse musculocutaneous gracilis (TMG) flap has become a popular choice for breast reconstruction. This study aimed to compare the donor site morbidity in unilateral and bilateral procedures. Patients receiving a TMG flap (January 2008–October 2019) were invited to a follow-up and grouped according to unilateral (UL group) or bilateral (BL group) breast reconstruction. Outcome criteria included sensation, function and aesthesis of the thighs. Patient-reported outcomes were surveyed using validated questionnaires. The number and kind of refinement procedures for aesthetic purposes on the donor thighs were evaluated. Thirty-eight patients with 59 TMG flaps were included in the study (UL group: n = 17, BL group: n = 21). Normal to slightly diminished superficial skin sensation was maintained in most of the thigh skin (98.4%). Strength and mobility were without impairment in >80% of the thighs in both groups. Thigh symmetry was achieved in both groups. Symmetrisation procedures were significantly more often performed in the UL group (p = 0.005). The total number of refinement procedures was similar in both groups. Patient-reported outcomes were similar with good appearance of the thighs and scars, excellent function and low pain levels. The TMG flap offers excellent function and sensation on the donor thigh. Thigh symmetry and good patient satisfaction may be achieved in both unilateral and bilateral breast reconstructions.

Morphological diagnosis and successful treatment of chorioptic mange in 2 South American coatis (Nasua nasua)

Two female South American coatis (Nasua nasua) kept in a zoo in Southern Germany presented with pruritus and moderate hair loss at the dorsal trunk, thigh areas and alongside the tail. Otherwise the animals showed no clinical signs. While the clinical general examination as well as cytology of dermatologic samples showed no pathologic changes, Chorioptes sp. mites could be identified in a superficial skin scraping. Two consecutive topical applications of a selamectin/sarolaner spot-on formulation 4 weeks apart lead to a complete resolution. No side effects were observed.

EP.FRI.537 Post-operative antibiotics for cutaneous abscess after incision and drainage: Variations in Clinical Practice or lack of guidelines

Aims Acute cutaneous abscess is a common surgical condition which mostly require incision and drainage. Despite this, there is no standardised national or international guidance on the post-operative antibiotics prescription. Traditionally, antibiotics are not indicated unless complications and/or risk factors such as immunocompromisation, diabetes or cellulitis exist. We aimed to study the local practice of the post-operative antibiotics prescription for cutaneous abscesses in a University teaching hospital in London. Methods A retrospective data collection of emergency general surgical admissions for a period of six months from July to December 2020 was carried out. All patients with superficial skin abscess were included in this analysis. Scrotal, breast and limb abscesses were excluded. Patients’ demographics, Co-morbidities, local and systemic complications were studied. Results A total of 149 patients presented during this period. Mean age was 40 (54% were male). Most common site of abscess was perianal (24%), followed by pilonidal, axilla, back, gluteal, neck, abdominal wall and groin. At total of 108 (72.5%) were managed surgically with incision and drainage, 70 (65%) got antibiotics and only 23 (33%) had indications for it (i.e. diabetic, immunocompromised, sepsis, cellulitis, MRSA carriage) = (χ2[1] =22.03, p&lt;.0001). Co-amoxiclav was the most common post-operative empirical antibiotic prescribed in 61% of the patients. Conclusions This study has identified significant variation in clinical practice regarding post-operative antibiotic usage in superficial abscesses. Further research is required in cooperation with microbiologists to develop standardised evidence-based treatment protocol for management of such common surgical condition.

Superficial mycosis, at the site or distant to the surgical site, appears to predispose patients to bacterial periprosthetic joint infections

Background: It is traditionally believed that presence of fungal infection in the nail or skin of patients is a risk factor for subsequent infection. The literature is devoid of any evidence to confirm or refute this belief. This study examined a possible relationship between the presence of superficial skin or nail mycoses and subsequent periprosthetic joint infection (PJI) in patients undergoing total joint arthroplasty (TJA). Methods: This is a single-centre, retrospective study of patients who underwent primary TJA between 2000 and 2018. 55 patients with superficial mycoses of skin or nail, at the time of arthroplasty were identified and a variable number matching with up to a 1:5 ratio was performed with 182 patients undergoing TJA who had no superficial mycosis. The groups were further divided into knee and hip TJA. The outcome of TJA in the cohorts was compared. Results: Preoperative demographics were similar between the 2 groups. The incidence of PJI in patients undergoing TKA within a year was significantly higher in patients with superficial mycosis at 8.6% (3/35) compared to 0% (0/120) in patients without mycosis. However, all infections were caused by bacterial species and none were fungal. Multiple regression analysis demonstrated that the presence of superficial mycosis had a strong correlation with development of PJI postoperatively in our TKA cohort. Conclusions: Identification of fungal infection (mycosis) of skin and nail in patients awaiting TJA is important. These patients appear to have a higher risk for developing bacterial PJI than those without fungal infections. Further study is needed to determine if treatment of these patients prior to arthroplasty stands to reverse the high risk for PJI that these patients carry.

Antimicrobial and Wound Healing Activity of Gardenia aqualla Stem Bark Methanol Extract

Aim: This study was aimed at examining the antimicrobial and wound healing activities of Gardenia aqualla stem bark methanol extract (GASBME) in order to provide scientific basis for its antimicrobial and wound healing properties. Methodology: Preliminary phytochemical screening was done and antimicrobial activity determined using some pathogenic micro-organisms were evaluated following its wound healing effectiveness in Wistar rats using the model of superficial skin excision wound. Data were analysed using one-way analysis of variance (ANOVA) followed by Dunnet’s t-test. Results: The results of preliminary phytochemical screening revealed the presence of carbohydrate, cardiac glycosides, saponins, flavonoids, triterpenes, tannins, alkaloids with anthraquinones being absent. The extract showed antimicrobial activity on Staphylococcus aureus, Corynebacterium ulcerans, Escherichia coli, Klebsiella pneumonia and Salmonella typhi and significant (p< 0.05, p< 0.001) decrease in wound measurement by the 11th day. Conclusion: This study demonstrated that GASBME possesses antimicrobial activity with wound healing properties that justifies the ethno-medicinal use of the plant in wound/ulcer healings.

The perils of penile enhancement: case report of a fulminant penile infection

Background Penile enhancement with injectable agents is a rising trend and yet has received little scientific attention despite the potential for serious complications. These include cosmetic, functional and systemic complications that may require complex penile reconstructive surgery. We report a case of delayed severe infection following penile filler insertion leading to multi-organ failure and intensive care support. Case presentation A 31-year-old man presented with fevers and progressive pain and swelling of the penile shaft, 3 days after unprotected sexual intercourse. The patient received subcutaneous hyaluronic filler injections at a cosmetic clinic for penile enlargement two months prior to presentation. Relevant social history include polysubstance abuse and multiple sexual partners. Physical examination revealed gross penile oedema and erythema, with a ventral curvature of the penile shaft and a superficial abrasion on the distal ventral penile shaft. Within 24 h the patient developed septic shock with anuria, hypotension and fevers to 40 °C, requiring transfer to the Intensive Care Unit (ICU) for vasopressor and inotropic support. Intraoperative penile exploration revealed multiple pus stained fillers which were drained and grew Streptococcus Pyogenes on cultures. There was no abscess or evidence of necrotising fasciitis intraoperatively. The patient improved with intravenous antibiotics and was stepped down from the ICU after four days and discharged on day eight. One month post admission there was significant superficial skin loss to both ventral and lateral aspect of the penis, with healthy granulation tissue at the base. The patient opted for conservative management with regular dressings. He reported normal sexual and urinary function three months post admission. Conclusion This is the first published case of sepsis from a penile infection in the context of hyaluronic acid penile fillers. In an era of escalating demand for penile cosmetic procedures, there is an increasing need for early recognition and appropriate management of penile filler infections. We report an unusual case of a localised penile infection rapidly progressing to sepsis with multi-organ failure requiring intensive care support. The case demonstrates early surgical intervention with targeted antimicrobials can result in successful eradication of infection, with satisfactory cosmetic and functional outcomes for patients.
