This feature reduces the direct stimulation to the spinal cord tissue by the elastomer and then reduces the immune response or resistance caused by the host spinal cord tissue. Second, the IKVAVS peptide modifies PSeD to create a bioactive interface to support NSC growth and differentiation. In the in vivo study, the number of CD68-positive macrophages decreased in the PSeD-IKVAVS/NSC group compared to that in the SCI group (20% vs 60%). The low inflammation induced by the scaffold was beneficial to NSCs, resulting in increased locomotor recovery, as indicated by the increased Basso-Beattie-Bresnahan score (5, the average score in the PSeD-IKVAVS/NSC group, vs 2, the average score in the SCI group). Based on the above two characteristics, a PSeD-IKVAVS bioelastomer is fabricated, which provides a beneficial and bioactive microenvironment for NSCs after transplantation.Structural bone allograft transplantation remains one of the common strategies for repair and reconstruction of large bone defects. Due to the loss of periosteum that covers the outer surface of the cortical bone, the healing and incorporation of allografts is extremely slow and limited. To enhance the biological performance of allografts, herein, we report a novel and simple approach for engineering a periosteum mimetic coating on the surface of structural bone allografts via polymer-mediated electrospray deposition. This approach enables the coating on allografts with precisely controlled composition and thickness. In addition, the periosteum mimetic coating can be tailored to achieve desired drug release profiles by making use of an appropriate biodegradable polymer or polymer blend. The efficacy study in a murine segmental femoral bone defect model demonstrates that the allograft coating composed of poly(lactic-co-glycolic acid) and bone morphogenetic protein-2 mimicking peptide significantly improves allograft healing as evidenced by decreased fibrotic tissue formation, increased periosteal bone formation, and enhanced osseointegration. Taken together, this study provides a platform technology for engineering a periosteum mimetic coating which can greatly promote bone allograft healing. This technology could eventually result in an off-the-shelf and multifunctional structural bone allograft for highly effective repair and reconstruction of large segmental bone defects. The technology can also be used to ameliorate the performance of other medical implants by modifying their surfaces.Providing control over the geometric shape of cell-laden hydrogel microspheroids, such as diameter and axial ratio, is critical for their use in biomedical applications. Building on our previous work establishing a microfluidic platform for production of large cell-laden microspheres, here we establish the ability to produce microspheroids with varying axial ratio (microrods) and elucidate the mechanisms controlling microspheroidal geometry. Microspheroids with radial diameters ranging from 300 to over 1000 μm and axial ratios from 1.3 to 3.6 were produced. Although for microfluidic devices with small channel sizes (typically less then 500 μm) the mechanisms governing geometric control have been investigated, these relationships were not directly translatable to production of larger microspheroids (radial diameter 102 - 103 μm) in microfluidic devices with larger channel sizes (up to 1000 μm). In particular as channel size was increased, fluid density differences became more influential in geometric control. We found that two parameters, narrowing ratio (junction diameter over outlet diameter) and flow fraction (discrete phase flow rate over total flow rate), were critical in adjusting the capillary number, modulation of which has been previously shown to enable control over microspheroid diameter and axial ratio. By changing the device design and the experimental conditions, we exploited the relationship between these parameters to predictably modulate microspheroid geometric shape. Finally, we demonstrated the applicability to tissue engineering through encapsulation of fibroblasts and endothelial colony forming cells (ECFCs) in hydrogel microspheroids with different axial ratios and negligible loss of cell viability. This study advances microfluidic production of large cell-laden microspheroids (microspheres and microrods) with controllable size and geometry, opening the door for further investigation of geometric shape-related biomedical applications such as engineered tissue formation.Recent advances in embedded three-dimensional (3D) bioprinting have expanded the design space for fabricating geometrically complex tissue scaffolds using hydrogels with mechanical properties comparable to native tissues and organs in the human body. The advantage of approaches such as Freeform Reversible Embedding of Suspended Hydrogels (FRESH) printing is the ability to embed soft biomaterials in a thermoreversible support bath at sizes ranging from a few millimeters to centimeters. In this study, we were able to expand this printable size range by FRESH bioprinting a full-size model of an adult human heart from patient-derived magnetic resonance imaging (MRI) data sets. We used alginate as the printing biomaterial to mimic the elastic modulus of cardiac tissue. In addition to achieving high print fidelity on a low-cost printer platform, FRESH-printed alginate proved to create mechanically tunable and suturable models. EGFR inhibitor This demonstrates that large-scale 3D bioprinting of soft hydrogels is possible using FRESH and that cardiac tissue constructs can be produced with potential future applications in surgical training and planning.The human amniotic membrane (HAM) has been viewed as a potential regenerative material for a wide variety of injured tissues because of its collagen-rich content. High degradability of HAM limits its wide practical application in bone tissue engineering. In this study, the natural matrix of the decellularized amniotic membrane was developed by the double diffusion method. The results confirmed a reduction of the amniotic membrane's degradability because of the deposition of calcium and phosphate ions during the double diffusion process. Real-time PCR results showed a high expression of osteogenesis-related genes from adipose-derived mesenchymal stem cells (ADMSCs) cultured on the surface of the developed mineralized amniotic membrane (MAM). Further in vivo experiments were conducted using an MAM preseeded with ADMSCs and a critical-size rat calvarial defect model. Histopathological results confirmed that the MAM + cell sample has excellent potential in bone regeneration.EGFR inhibitor

In turn, high content of IL-6 in the medium activated JAK2/STAT3, MEK/ERK, and PI3K/AKT pathways in HiBECs, inducing HiBEC abnormal proliferation and migration. Together, these results suggested that MC-LR-mediated interaction between HiBECs and macrophages induced the M2-type polarization of macrophages, and activated IL-6/JAK2/STAT3, MEK/ERK, and PI3K/AKT pathways in HiBECs, further enhanced cell proliferation, improved cell migration, and hindered cell apoptosis by activating p-STAT3. MC-LR stimulates HiBECs to produce various inflammatory factors, recruiting a large number of macrophages and promoting the differentiation of macrophages into M2-type. In turn, the M2 macrophages could also produce amounts of IL-6 and activate STAT3 through JAK2/STAT3, MEK/ERK, and PI3K/AKT pathways in HiBECs, resulting in the promotion of cell proliferation, inhibition of apoptosis, and enhancement of migration.Transdermal drug delivery systems have become an intriguing research topic in pharmaceutical technology area and one of the most frequently developed pharmaceutical products in global market. The use of these systems can overcome associated drawbacks of other delivery routes, such as oral and parenteral. check details The authors will review current trends, and future applications of transdermal technologies, with specific focus on providing a comprehensive understanding of transdermal drug delivery systems and enhancement strategies. This article will initially discuss each transdermal enhancement method used in the development of first-generation transdermal products. These methods include drug/vehicle interactions, vesicles and particles, stratum corneum modification, energy-driven methods and stratum corneum bypassing techniques. Through suitable design and implementation of active stratum corneum bypassing methods, notably microneedle technology, transdermal delivery systems have been shown to deliver both low and high molecular weight drugs. Microneedle technology platforms have proven themselves to be more versatile than other transdermal systems with opportunities for intradermal delivery of drugs/biotherapeutics and therapeutic drug monitoring. These have shown that microneedles have been a prospective strategy for improving transdermal delivery systems.Asthma is a common, chronic inflammatory airway disease, characterised by unpredictable episodes of worsening symptoms, or exacerbations. Causes of asthma exacerbations include viral infections, exposure to allergen and air pollution, all of which increase the underlying inflammation that typifies asthma. Most (50-75%) patients are classed as having mild asthma, with symptoms that can be readily controlled with available inhaled medications. Paradoxically, for the past 30 years, the first treatment recommended in asthma management guidelines was short-acting β2-agonists (SABA), which not only have no anti-inflammatory properties but may, in fact, worsen inflammation. The Global Initiative for Asthma (GINA) 2019/2020 broke with this paradox by stating clearly that SABA should no longer be used alone as a reliever, for safety reasons. Instead, GINA now recommends an anti-inflammatory rescue/reliever approach for adult and adolescent patients, based on the combination of an inhaled corticosteroid with a rapid onset β2-agonist such as formoterol. This commentary highlights the fact that even patients with well-controlled mild asthma are at risk of severe, potentially life-threatening exacerbations, similar to those in patients with moderate or severe asthma, and therefore 'mild asthma', is a misnomer. The commentary describes the case history of a patient with mild asthma to illustrate how increasing use of SABA alone can worsen and prolong exacerbations when they occur. The author goes on to describe how the management of this patient's exacerbation could have been improved, and provides up-to-date advice on broader aspects of the management of mild asthma and exacerbations, supported by the recent changes to the GINA recommendations.
The DAPA-CKD trial assessed dapagliflozin in patients with chronic kidney disease (CKD) with or without type 2 diabetes (T2D). To aid interpretation of results, renal and cardiovascular outcomes plus healthcare resource utilization (HCRU) and costs were assessed in a real-world population similar to that of DAPA-CKD.

Henry Ford Health System (2006-2016) data were used to identify patients with CKD stages 2-4 [estimated glomerular filtration rate (eGFR) 25-75ml/min/1.73m
at index and urine albumin-to-creatinine ratio (UACR) 0-5000mg/g; n = 22,251]. Included patients had confirmatory eGFR ≥ 90days post-index and no kidney transplant or progression to end-stage kidney disease during 12months pre-index. The final population (n = 6557) was stratified by UACR (0-29, 30-199 and 200-5000mg/g; the last comprising the DAPA-CKD-like cohort). Patients were followed for 5years post-index.

Adverse clinical outcomes incidence increased with UACR and was highest for the DAPA-CKD-like cohort (UACR 200-5000mg/g) versus significant adverse renal and cardiovascular outcomes observed, particularly in the DAPA-CKD-like cohort, represent a substantial burden resulting in increased mortality, HCRU and costs, demonstrating the need for additional treatment options.
Our aim is to propose an evidence-based strategy for screening postpartum dysglycemia.

This study included adult non-pregnant women who were diagnosed with gestational diabetes (GDM) using International Association of Diabetes in Pregnancy Study Group (IADPSG) criteria during their index pregnancy (2012-2019). Eligible participants underwent a concurrent oral glucose tolerance test (OGTT) and glycated hemoglobin (HbA1c) test. A detailed questionnaire documenting relevant personal and medical history was filled, and the relevant anthropometric parameters were recorded.

We evaluated data from 377 women at a mean (± SD) age of 32.1 ± 4.6years and at a median duration of 15 (10-33) months following childbirth. Diabetes was diagnosed in 42 (11.1%) women. Use of a combination cutoff [fasting plasma glucose (FPG) ≥ 6.1mmol/L or glycated hemoglobin (HbA1c) ≥ 6.0% (42mmol/mol)] avoided OGTT in 80.9% of the study cohort, without missing the diagnosis of diabetes in any study subject. The diagnosis was missed in 2.check details

There were 3 revisions; one each for taper corrosion, recurrent dislocation, and infection. Radiographically, all cups had evidence of osteointegration and none had radiographic evidence of loosening. The mean Harris Hip Score improved from 50 to 84 postoperatively (P < .0001).

Contemporary porous titanium acetabular components with supplemental screws provided excellent implant fixation in patients with prior therapeutic pelvic radiation. At 10 years, 100% of these components were free of revision for aseptic loosening and 100% were radiographically well-fixed.

Unicompartmental knee arthroplasty (UKA) indications have expanded during the past two decades to include some morbidly obese patients (body mass index (BMI) > 40 kg/m
). Few published studies have compared UKA and total knee arthroplasty (TKA) in this unique patient subgroup with conflicting observations.

We retrospectively compared 89 mobile bearing UKA (71 patients) and 201 TKA (175 patients) performed at a single institution with a minimum 2-year follow-up (mean 3.4 years). Demographic characteristics were similar for both patient cohorts. A detailed medical record review was performed to assess the frequency of component revision, revision indications, minor secondary procedures (components retained), and infections.

UKA was more frequently associated with clinical failure (29.2% vs 2.5%, P < .001) and component revision (15.7% vs 2.5%, P < .001), TKA was more frequently associated with extensor mechanism complications or knee manipulation (5.5% vs 0.0%, P= .02), and there was no difference in the infection rate (3.0% vs 2.2%, P= 1.0).

Early complications were lower following UKA but were outweighed by higher component revision rates for arthritis progression and implant failure. The study findings suggest that TKA provides a more predictable mid-term outcome for morbidly obese patients considering knee arthroplasty surgery.

This was a retrospective study on pediatric patients with mandible fracture. The primary objective was a comparison of outcomes in terms of bone healing, maximal incisal opening (MIO), and occlusion, and the secondary objective was to review complications. A total of 77 pediatric patients (age less then 12 years) were managed with closed treatment and 23 with ORIF. In all, 62 patients were found with a single fracture (22 patients with parasymphysis fracture and 21 with condyle fracture, followed by symphysis, angle, and body fracture) and 38 patients with more than one fracture, with symphysis and bilateral condyle fracture being the most common. Bone healing was observed in all the patients. Mean MIO was 26.9 ± 2.8 mm and 29.3 ± 1.7 mm in the closed and ORIF group, respectively, and the difference was statistically nonsignificant (p = 0.5). One patient (1.3%) had deranged occlusion, and mobility was observed in one patient (1.3%) in the closed treatment group. Infection and nerve paresthesia were not seen in any patient at follow-up. Although closed treatment is preferred, as it preserves the soft tissue and periosteum, a displaced mandible fracture especially with co-existing condylar fracture should be treated by ORIF.This study investigated the cotransplantation of bone marrow mesenchymal stromal cells (BMSC) and human umbilical cord endothelial cells (HUVEC), and evaluated their contribution to vascular and bone tissue engineering in vivo. To evaluate the success of osteogenic differentiation and timely vascularization of different osteoconductive scaffolds in vivo, we transferred BMSC and HUVEC pre-cultivated calcium carbonate (CaCO3) and hydroxylapatite (HA) matrices into immunocompromised RNU-rats, and analyzed mineralization, expression of osteopontin, and vascular integration via new vessel formation. After in vivo transplantation, pre-cultivated scaffolds demonstrated overall improved mineralization of 44% for CaCO3 (p = 0.01, SD ± 14.3) and 34% for HA (p = 0.001, SD ± 17.8), as well as improved vascularization of 5.6 vessels/0.1 mm2 on CaCO3 (p less then 0.0001, SD ± 2.0) and 5.3 vessels/0.1 mm2 on HA (p less then 0.0001, SD ± 2.4) compared with non-pre-cultivated controls. NX-5948 supplier However, no significant differences between the implantation of BMSC-only, HUVEC-only, or BMSC + HUVEC cocultures could be observed. There is an increasing demand for improved bone regeneration in tissue engineering. Cotransplantation of mesenchymal stromal cells and endothelial cells often demonstrates synergistic improvements in vitro. However, the benefits or superiority of cotransplantation was not evident in vivo and so will require further investigation.Acute kidney injury is a major cause of in-hospital morbidity and mortality because of the serious nature of the underlying illnesses and the high incidence of complications. The two major causes of acute kidney injury that occur in the hospital are prerenal disease and acute tubular necrosis. Acute tubular necrosis has a histological definition, even if a kidney biopsy is rarely performed. Kidney injuries occurring during acute tubular necrosis are underlined by different pathophysiological mechanisms that emphasize the role of hypoxia on the tubular cells such as apoptosis, cytoskeleton disruption, mitochondrial function and the inflammation mediated by innate immune cells. The microcirculation and the endothelial cells are also the targets of hypoxia-mediated impairment. Repair mechanisms are sometimes inadequate because of pro-fibrotic factors that will lead to chronic kidney disease. Despite all the potential therapeutic targets highlighted by the pathophysiological knowledge, further works remain necessary to find a way to prevent these injuries.NX-5948 supplier

Introduction Hospitalized patients are at risk of unrecognized clinical deterioration that may lead to adverse events.Context Rapid Response Teams (RRTs) exist around the world as a strategy to improve patient safety.Objective To explore how RRTs work, their characteristics, impacts, and methods of implementation.Design Literature review.Method Consultation of the databases CINAHL, MEDLINE, PUBMED, COCHRANE library, SCOPUS, and PROQUEST Dissertations and Theses. Keywords “health care team” and “rapid response team”.Results 121 articles were included. The collected data were divided into five categories 1) composition and operation of RRTs, 2) benefits and limitations of RRTs, 3) perceptions of RRTs by health care teams, organizations, and patients, 4) implementation strategies, and 5) facilitators and barriers to implementation.Discussion Although there are many articles related to RRTs, it appears that 1) few studies analyze the difference in outcomes in hospitalized patients related to the composition of RRTs, 2) few studies describe how RRTs should work, 3) more studies are needed on the impacts of RRTs on hospitalized patients, 4) organizations’ and patients’ perceptions of RRTs are not well studied, and 5) more studies are needed on the best way to implement an RRT.Conclusion The results show that there is a lack of studies on the difference in outcomes in hospitalized patients related to the composition of RRTs, on how RRTs should work, on the impacts of RRTs on hospitalized patients, on organizations’ and patients’ perceptions of RRTs, and on the factors that influence the success or failure of the implementation of an RRT.Introduction Wound care represents a public health issue and is an important concern for nursing care.Context Despite the availability of best practice recommendations and clinical practice guidelines, there is a lack of use of this evidence in clinical practice.Objectives The aim of this integrative review is to identify the barriers to nurses’ optimal knowledge transfer in wound care.Method An integrative literature review based on Whittemore and Knalf’s (2005) methodology was conducted ; six databases were searched.Results Of the 82 articles that were retrieved, 13 were retained for analysis. PI3K inhibitor They were all published in English. The literature highlights a theory–practice gap in wound care. Barriers related to knowledge, attitudes, and environmental factors contribute to this gap.Discussion Nursing could benefit from interventions to improve its role in wound care. The perspectives of new graduate nurses as well as nurses working in rural healthcare settings were limited.Conclusion A strategic plan, adapted to the situation of each healthcare facility, could improve the quality of wound care practice.Introduction Compliance with hygiene rules constitutes a central element of care practices in general and nursing training in particular. This study seeks to comprehend the behaviors associated with adherence to rules of hygiene based on the discourse of students in nursing training. The theoretical frame of reference is ethogenic and aims to explain the behaviors through the social conventions, culture and environment of care professionals.Method 159 students in training were interviewed in focus groups to evoke the themes of violation of and adherence to hygiene rules.Results The participants’ comments collected illustrate that behaviors depend upon the perception of the contexts of care, skills and recognition within an in-training professional care work group.Conclusion The results emphasize the importance of developing rules-based education on hygiene, while avoiding the establishment of resistance associated with the application of rules of hygiene in the workplace.Introduction People living with type 2 diabetes are brought to make demanding behavioral changes that can lead to self-management difficulties.Background The guidelines recommend that healthcare professionals follow a person-centered approach (PCA) when caring. However, this approach seems difficult to adopt in practice.Objective Coconstruct an intervention inspired by the concept map (CM) to promote the adoption of PCA by nurses during self-management support encounters.Method This study is based on a model for developing evidence-based nursing interventions. Five experts (2 patients, 2 nurses, 1 educational specialist) collaborated in the coconstruction of the intervention.Results The Person-Centered Approach Diabetes Self-Management Support (PCA-DSMS) intervention has been developed in accordance with the foundations of a PCA and the CM. It includes four steps 1) Introduce the intervention ; 2) Develop the Needs Map ; 3) Intervene according to priority needs ; 4) Conclude and plan a follow-up.Discussion More studies are needed to explore whether the intervention is acceptable and feasible as well as its ability to lead nurses to adopt PCA.Conclusion The PCA-DSMS could bring nurses to adopt a PCA.Introduction The caritative impact of nursing care provided in forensic mental health settings is rarely questioned.Context Caritative nursing care is indirectly regulated by the Review Board (RB), a para-judicial court which ensures public safety.Objective This study presents a critical reflection on the political and social effects of the RB, forensic psychiatry hospitals and practices of forensic mental health nurses.Method The reflection is centered on the concepts of biopower, degradation ceremonies, moral career and identity (re)construction.Results ‘Therapeutic’ nursing practices are useful for disciplinary purposes in the forensic psychiatric hospital, insofar as they permit the identification and management of dangerous persons. However, the practices also fall within the biopolitical scope of the RB, since they assist the latter in ensuring public safety.Discussion The forensic psychiatric environment can prove problematic for nurses, requiring a double allegiance, whereby their responsibilities to patients (consent and confidentiality) and to the institution (protection of the public) can lead to tension.PI3K inhibitor

002). The mean time to return to nicotine postoperatively was 2.4 months. The number of preoperative cigarettes per day was the only independent predictor of tobacco use relapse (P=0.005). Conclusion Mandatory preoperative nicotine cessation prior to elective hip surgery demonstrates a 46.7% nicotine-free survivorship at final follow-up with the number of preoperative cigarettes per day found to be the only independent predictor of nicotine use relapse. Level of evidence The level of evidence of this research study is Level III since it is a non-experimental study with a cohort of patients.Odontoid fracture is the most common type of cervical spine fracture in the elderly. Neurological injury due to odontoid fracture is uncommon, but if the injury is severe, it can lead to cardiac arrest. We present a case of odontoid fracture with transient cardiac arrest just after the fall, which fully recovered in a few minutes before arrival at the hospital. A 62-year-old man fell down on a street, and compressions were performed by a witness. On arrival of the emergency medical service, he showed pulseless electrical activity. After two minutes of cardiac resuscitation, he experienced a return of spontaneous circulation and was breathing spontaneously. On arrival at our hospital, his blood pressure was 171/106 mmHg, heart rate was 100 beats per minute, and respiratory rate was 12 times per minute, but he was at Glasgow Coma Scale 3 with an alcohol odor from exhaled breath. Six hours after admission, his level of consciousness improved, and he complained of neck pain and difficulty in movement of his arms and legs. CT revealed a fracture and posteriorly displaced C2 bone. MRI showed a hyper-intense area from C1 to C2. We made a diagnosis of spinal cord injury caused by an odontoid fracture that led to cardiac arrest. An odontoid fracture can cause transient cardiac arrest just after a fall. The possibility of odontoid fracture associated cervical spine injury should be considered in elderly and unconscious patients with minor trauma. Early CT cervical spine in selected patients can be helpful, especially in patients with cardiac arrest, even if it lasted for only a short prehospital period.A rectus sheath hematoma (RSH) is a rare medical condition that consists of blood accumulating in the rectus abdominis muscle sheath. RSH is most frequently due to a hemorrhage from the superior or inferior epigastric artery. RSH has many specific risk factors, such as anticoagulant use. As the use of anticoagulants increases, the incidence of RSH has also increased. This condition can present with the infrequent complication of abdominal compartment syndrome (ACS), which can require surgical decompression of the abdomen to avoid high morbidity and mortality. We present the case of a 79-year-old male who, after receiving anticoagulants, developed a right-sided RSH which progressed to ACS. The patient was transferred to our care for community-acquired pneumonia, pneumothorax, and increasing respiratory support. He was admitted to the medical intensive care unit (MICU), was placed on a nasal cannula, and given vancomycin and Zosyn for pneumonia. After two days, the patient was switched to enoxaparin for anticoaause there is an absence of the posterior rectus sheath which enables the hematomas to spread. Chroman 1 An RSH can be treated with conservative measures, but for patients who continue to bleed, more aggressive measures should be taken to avoid life-threatening complications, such as ACS.Renal-limited pauci-immune necrotizing glomerulonephritis presenting as acute encephalopathy is a rare occurrence. A 67-year-old Hispanic male presented to the hospital after being found down. He was found to have acute renal failure and high anion gap metabolic acidosis. Hemodialysis did not improve his encephalopathy. A vasculitis workup resulted in a high antimyeloperoxidase (MPO) antibody level. Renal biopsy revealed globally sclerotic glomeruli with focal thickened capillary loops, suggestive of pauci-immune necrotizing and crescentic glomerulonephritis (GN). Treatment consisted of high dose methylprednisolone and rituximab for induction, and three cycles of plasmapheresis, in addition to hemodialysis for uremia. Upon discharge, he was continued on hemodialysis and continued treatment with prednisone. Patients who present acutely with persistent uremic encephalopathy despite hemodialysis may warrant pursuing an alternative diagnosis, such as glomerulonephritis. Prompt diagnosis and treatment are necessary to improve the prognosis since untreated pauci-immune glomerulonephritis carries a high mortality rate.There are many well-known risk factors for keloids and hypertrophic scars (HTS) including ethnicity, family history, and history of previous keloids or HTS. An association, which has been previously observed, exists between pregnancy and growth and worsening of keloid and HTS. This association is less well known amongst physicians and less documented in the literature. In this paper we discuss two cases of extreme worsening of keloid scars during pregnancy. We have also witnessed the transformation of a pre-existing scar into a keloid scar during puberty. We attribute this to the hormonal effects of pregnancy and puberty hormones which could potentially trigger the growth of pre-existing keloids and HTS. This may have an impact on many patients and we therefore recommend women and girls who have keloid and hypertrophic scarring be made aware of this potential effect.Necrotizing fasciitis is an uncommon and deadly disease entity characterized by rapidly progressing skin and soft tissue destruction. It presents on a spectrum from an initially indolent appearing sub-acute form to a hyperacute fulminant course. It may often be misdiagnosed due to the paucity of signs early in the disease course and as it can initially mimic other less serious soft tissue infections. Necrotizing soft tissue infections have both high morbidity and mortality. We present a case of a 72-year-old male patient with two anatomically and temporally separate necrotizing infections. The first necrotizing infection was diagnosed after an extended time, due to the subacute disease course in the setting of an abdominal wall infection. The second presentation was a hyperacute fulminant course in the setting of a necrotizing infection of the scrotum. In both instances, once identified, appropriate management was followed resuscitation, broad-spectrum antibiotics, and most importantly radical surgical debridement.Chroman 1
