Objective@#To investigate the clinical characteristics, diagnosis, treatment, and prognosis of descending necrotizing mediastinitis (DNM) to provide a reference for the early diagnosis and timely treatment of DNM.@*Methods@#Data on DNM in China was electronically retrieved from the core databases and comprehensively reviewed from June 2012 to June 2023. The infection, pathogenic microorganisms, main symptoms, comorbidities and treatment methods of DNM were analyzed.@*Results@#The data of a total of 781 DNM patients, with an average age of (52.97 ± 5.64) years, were retrieved, including 554 males and 227 females. Odontogenic source, tonsillitis, pharyngeal abscess, sialoadenitis, upper respiratory tract infection, foreign body injury, or iatrogenic traumatic procedures are common causes. Among these, odontogenic infection is the most common source. Streptococcus sp. (n = 217) and Staphylococcus sp. (n = 82) were most isolated, followed by Klebsiella pneumoniae and Pseudomonas aeruginosa (equally n = 59). A total of 69.4% (542/781) of DNM patients recruited in this study were discovered to have various comorbidities, and more than one-third of these patients (n = 185) had diabetes. Of the broad antibiotics, carbapenem was most frequently used as treatment, and vancomycin was the most frequently coadministered. The mediastinal drainage approach varies widely, and the optimal regimen is still unknown. Seventy-two patients were treated with video-assisted thoracoscopic/mediastinoscopic surgical drainage, 22 patients were treated with percutaneous catheter drainage, 30 underwent the transcervical approach, and 40 underwent thoracotomy. A total of 617 patients who were selected underwent the appropriate combined operation for surgical drainage according to the specific location of the infected focus. The overall mortality rate of all 781 DNM patients included was 11.2%.@*Conclusion@#The most effective diagnosis and treatment of DNM is a high degree of clinical vigilance followed by prompt and adequate drainage with intensive care, including hemodynamic monitoring, nutritional support, computer tomographic scanning repeated as necessary, and combined use of systemic antibiotics.

Fascitis necrotizante asociada a esteatohepatitis en el curso del lupus eritematoso sistémico

Introducción: La fascitis necrotizante es un cuadro muy grave causado por una infección bacteriana de la piel y de tejidos blandos subcutáneos, cuya evolución es hacia la destrucción y necrosis de los tejidos en un corto espacio de tiempo; el lupus eritematoso sistémico es una enfermedad autoinmune de causa desconocida que quienes la padecen tienen una mayor probabilidad de contraer infecciones debido al mal funcionamiento del sistema inmunológico y/o los efectos secundarios causados por los medicamentos. Objetivo: Observar la importancia de un tratamiento rápido y eficaz de la fascitis necrotizante en un paciente con lupus eritematoso sistémico y esteatohepatitis no alcohólica. Presentación de caso: Se presentó el caso clínico de un paciente de 30 años con diagnóstico de lupus eritematoso sistémico que desarrolló de forma concomitante de fascitis necrotizante y esteatohepatitis no alcohólica. A pesar de un tratamiento adecuado, el paciente fue agresivo. Tuvo una estadía hospitalaria de 83 días, con una evolución desfavorable que conllevó a la muerte.

Introduction: Necrotizing fasciitis is a very serious condition caused by a bacterial infection of the skin and subcutaneous soft tissues, whose evolution is towards the destruction and necrosis of the tissues in a short space of time; Systemic lupus erythematosus is an autoimmune disease of unknown cause that sufferers are more likely to contract infections due to poor immune system function and/or side effects caused by medications. Objective: To observe the importance of rapid and effective treatment of necrotizing fasciitis in a patient with systemic lupus erythematosus and non-alcoholic steatohepatitis. Case report: We report the clinical case of a 30-year-old patient diagnosed with systemic lupus erythematosus who concomitantly developed necrotizing fasciitis and nonalcoholic steatohepatitis. Despite adequate treatment, the patient was aggressive. The patient had a hospital stay of 83 days, with an unfavorable evolution that led to his death.

Fascitis necrosante periocular

La fascitis necrosante es una enfermedad rara y potencialmente mortal, que se produce por una infección grave que se disemina desde las fascias superficiales destruyendo el tejido celular subcutáneo y la piel suprayacente. Las formas perioculares de la enfermedad son aún más raras y pueden tener graves consecuencias para el paciente. El objetivo de este estudio fue contrastar los hallazgos clínicos y los resultados terapéuticos en una serie de cuatro casos diagnosticados en el Centro Oftalmológico de Holguín en el curso de cinco años. Entre 2017 y 2022 se diagnosticaron cuatro pacientes con formas perioculares de fascitis necrosante en el Centro Oftalmológico de Holguín. Dos pacientes tuvieron antecedentes de trauma menor. El dolor predominó entre los síntomas locales. Se identificaron dos patrones de lesiones: bilateral con ulceración y afectación de la región palpebral superior y unilateral con extensión en ambos párpados y apariencia oscura de la piel. Los pacientes evolucionaron a la gravedad con deterioro del estado general. El desbridamiento del tejido necrótico y el tratamiento con antibióticos de amplio espectro permitieron detener el progreso de la enfermedad, aunque quedaron secuelas anatómicas y funcionales. Un paciente falleció como consecuencia de una leucemia diagnosticada durante su ingreso. El reconocimiento temprano de la fascitis necrosante periocular y su inmediato tratamiento es indispensable para garantizar resultados óptimos y la supervivencia del paciente. Las formas perioculares pueden tener apariencia clínica diversa, lo que debe ser tenido en cuenta ante la sospecha de este cuadro, sobre todo por la similitud inicial con la celulitis preseptal.

Necrotizing fasciitis is a rare and potentially fatal disease caused by a severe infection that spreads from the superficial fasciae destroying the subcutaneous cellular tissue and overlying skin. Periocular forms of the disease are even rarer and can have serious consequences for the patient. The aim of this study was to contrast clinical findings and therapeutic outcomes in a series of four cases diagnosed at the Holguin Ophthalmology Center over the course of five years. Between 2017 and 2022, four patients with periocular forms of necrotizing fasciitis were diagnosed at the Holguín Ophthalmologic Center. Two patients had a history of minor trauma. Pain predominated among the local symptoms. Two patterns of lesions were identified: bilateral with ulceration and involvement of the upper palpebral region and unilateral with extension in both eyelids and dark appearance of the skin. Patients progressed to severity with deterioration of general condition. Debridement of necrotic tissue and treatment with broad-spectrum antibiotics halted disease progression, although anatomical and functional sequelae remained. One patient died as a result of leukemia diagnosed during his admission. Early recognition of periocular necrotizing fasciitis and its immediate treatment is essential to ensure optimal outcome and patient survival. Periocular forms can have different clinical appearances, which should be taken into account when suspecting this condition, especially due to the initial similarity with preseptal cellulitis.

Standardization of reconstructions with flaps after Fournier's gangrene / Padronização das reconstruções com retalhos após gangrena de Fournier

Introduction: Fournier's gangrene is characterized by tissue necrosis, which requires treatment employing debridement and antibiotics with wounds of varying sizes. The objective is to standardize the surgical techniques of reconstructions with flaps used to treat wounds after Fournier's gangrene. Method: A study was conducted by searching the PubMed/Medline, SciELO, and LILACS databases. Results: In wounds with skin loss of 25% to 50%, a local advancement cutaneous flap or a pudendal flap from the thigh was used; in wounds, greater than 50%, a superomedial thigh flap or myocutaneous flap from the gracilis muscle was used, with the aim of to enable proper reconstruction. Conclusion: Advancement and pudendal thigh flaps were used for wounds with up to 50% loss of scrotal skin substance, while the myocutaneous gracilis flap and supero-medial flap of the thigh were indicated for wounds with more than 50% of the total scrotal surface affected, after Fournier gangrene.

Introdução: Gangrena de Fournier é caracterizada por necrose tecidual, que necessita de tratamento por meio de desbridamento e antibióticos, com feridas de dimensões variadas. O objetivo é padronizar as técnicas cirúrgicas de reconstruções com retalhos utilizadas no tratamento das feridas após gangrena de Fournier. Método: Realizou-se estudo por meio da busca nas bases de dados PubMed/Medline, SciELO e LILACS. Resultados: Nas feridas com perdas cutâneas de 25% a 50%, foram utilizados retalho cutâneo local de avanço ou retalho pudendo da coxa, nas maiores de 50% foram necessárias as confecções do retalho superomedial da coxa ou retalho miocutâneo do músculo grácil, com intuito de possibilitar a reconstrução adequada. Conclusão: Os retalhos de avanço e pudendo da coxa foram utilizados para feridas com perda de substância cutânea escrotal de até 50%, enquanto os retalhos miocutâneo de músculo grácil e superomedial da coxa foram indicados para as feridas com mais de 50% da superfície escrotal total acometida, após gangrena de Fournier.

Clinicoepidemiological profile of necrotizing fasciitis in a tertiary care center of western Odisha

Background: Necrotizing fasciitis (NF) is a state of infection promptly intensifying the destruction of skin with underlying tissue leading to permanent infirmity and high mortality irrespective of good parenteral drug coverage and contentious surgical handling. NF normally begins as a confined infective focus that initially presents as cellulitis later rapidly progresses to large areas of infection which disproportionate to pain. Aims and Objectives: The primary aim of this study is to determine the incidence and management methods of NF in tertiary health-care center of western Odisha. Materials and Methods: A retrospective review of medical records of patients diagnosed with NF presenting to department of general surgery, Veer Surendra Sai Institute of Medical Sciences and Research Burla, from March, 2020 to February, 2022 was performed. Various information such as patient’s demographics, type of presentation at the time of admission, age group affected, body parts affected, mode of injury, and microbiological status were collected in a predesigned format for analysis. Data were presented in number and percentage. Results: A cumulative of 96 cases with clinical features of NF was reviewed. The median age group range was 31–40 years. Nearly 94.7% cases had significant underlying comorbidities. Extremities were most commonly affected part. About 82.2% cases had undergone surgical debridement, 13.5% cases fasciotomy, and 4.2% cases skin grafting. Most common mode of injury is trivial injury. Group A Streptococcus is most common cause of organism. Almost 78.3% cases were healed. Conclusions: NF can induce upscaled morbidity and mortality if left undetected and untreated in primordial stages. The medics, paramedics, and specialists including surgeons need to have a high degree of intuition to diagnose NF at its beginning stages and thus precisely put resuscitative efforts, plan for debridement, and need for any urgent referral.

Cervical necrotizing fasciitis caused by oral cavity infection: a case report considering therapeutic approach and its morphofunctional implications / Fascitis necrosante cervical causada por infección de la cavidad oral. Reporte de un caso considerando el abordaje terapéutico y sus implicaciones morfofuncionales

SUMMARY: Cervical necrotizing fasciitis (NF) is a rare complication of oral cavity infection with high morbi-mortality. Given its low prevalence, adequately reporting cases of NF, its therapeutic management, and associated morphofunctional modifications to the clinical and scientific community is pivotal. To that end, we herein describe a case of cervical NF in a 60-year-old patient with comorbidities and patient presented large, painful cervical swelling associated with a necrotic ulcer lesion in the anterior neck region. Intraoral examination indicated a periodontal abscess in the right mandibular area, while computed tomography indicated the lesion's extension from the right mandibular to the submandibular region. Following empirical intravenous antibiotic treatment, a broad surgical debridement was performed, and the foci of oral infection were removed. Debridement revealed communication between deep and superficial anatomical regions in the submandibular area, where we subsequently placed a Penrose drain. Biopsies showing acute inflammatory infiltrate associated with necrotic and hemorrhagic regions confirmed the diagnosis of NF. When an antibiogram revealed resistance to the empirical treatment, the antibiotic scheme was replaced with an adequate alternative. After a second debridement, we closed the defect with fascio-mucocutaneous advancement flaps with a lateral base while maintaining suction drainage. Having reacted positively, the patient was discharged 10 days after the operation. Despite an extensive morphofunctional change generated in the treated area, the patient showed no difficulties with breathing, phonation, swallowing, or mobilizing the area during control sessions. Altogether, this report contributes to the highly limited literature describing morphological aspects that can facilitate or delay the spread of infection or the morphofunctional disorders associated with the size and depth of surgical interventions for cervical NF, information that is relevant for the comprehensive, long-term prognosis of the treatment of NF.

La fascitis necrosante (FN) cervical es una rara complicación de una infección proveniente de la cavidad bucal asociada a una alta morbimortalidad. Por lo anterior, es fundamental informar a la comunidad clínica y científica los casos de FN, su manejo terapéutico y las modificaciones morfofuncionales asociadas. Se describe un caso de FN cervical en una paciente de 60 años quien presentó una gran tumefacción dolorosa asociada a una lesión ulcerosa necrótica en la región anterior del cuello. El examen intraoral mostró un absceso periodontal en el área mandibular derecha y la tomografía computarizada mostró la extensión de la lesión hacia la región submandibular. Tras el tratamiento antibiótico empírico, se realizó un desbridamiento quirúrgico extenso y se extirparon los focos de infección oral. El desbridamiento reveló comunicación entre las regiones anatómicas profundas y superficiales del área submandibular, donde se colocó un drenaje Penrose. Las biopsias mostraron un infiltrado inflamatorio agudo asociado con regiones necróticas y hemorrágicas, confirmando el diagnóstico de FN. El antibiograma reveló resistencia al tratamiento empírico, por lo que el esquema antibiótico se sustituyó. Tras un segundo desbridamiento, se cerró el defecto con colgajos de avance fascio-mucocutáneos de base lateral manteniendo drenaje aspirativo. El positivo progreso del paciente permitió su alta 10 días después. Aun cuando se generó una gran modificación morfofuncional en el área tratada, la paciente no presentó dificultades para respirar, hablar, deglutir o movilizar el área cervical intervenida durante las sesiones de control. Este informe contribuye a la limitada literatura que describe los aspectos morfológicos que pueden facilitar o retrasar la propagación de la FN y las consecuencias asociadas a los trastornos morfofuncionales provocadas por el tamaño y profundidad de las intervenciones quirúrgicas requeridas por la FN, información relevante para el pronóstico integral a largo plazo del tratamiento de la FN.

Conclusiones: La membrana amniótica como material de apósito presentó resultados favorables en la paciente al obtenerse una rápida regeneración de la secuela producida por la fascitis necrotizante.

Introduction: Necrotizing fasciitis is a serious infection that involves the skin, the subcutaneous tissue, and the superficial-deep fascia, it progresses very quickly and if not treated in time it can cause death. Report case: We present the case of an adult patient with a history of anemia, who was diagnosed with odontogenic necrotizing fasciitis, for which she underwent surgery and underwent intraoral and extraoral drainage plus escharectomy. In addition, pharmacological treatment (intravenous antibiotics) was administered, and an amniotic membrane was placed as a dressing material to reconstruct the hemorrhagic surface left by the necrotizing fasciitis. Conclusions: The amniotic membrane as a dressing material presented favorable results in the patient, obtaining a rapid regeneration of the sequel produced by necrotizing fasciitis.

Clinical characteristics, ultrasonic diagnosis, treatment and outcomes of eosinophilic fasciitis: a retrospective single-center analysis of 45 cases / 南方医科大学学报

OBJECTIVE@#To evaluate the clinical features, laboratory and imaging results, treatment and outcomes of eosinophilic fasciitis (EF) and assess the value of ultrasound in the diagnosis of EF.@*METHODS@#We retrospectively analyzed the clinical data of 45 patients with EF treated in our center from January 1, 2006 to February 28, 2022. The consistency between the diagnoses of EF based on ultrasound and MRI findings was assessed.@*RESULTS@#In the 45 EF patients (male/female ratio 3.5:1), the age of onset ranged from 16 to 64 years with a mean disease course of 22.6 months. The average time from symptom onset to diagnosis was 16 months. The most common possible trigger of the disease was vigorous exercise (10/45), causing symmetrical lesions in the limbs, most commonly in the forearms (86.7%) and lower legs (80%). Clinical features of EF included subcutaneous swelling and induration (95.6%), arthralgia and arthritis (55.6%), groove sign (42.2%), hand joint contractures (42.2%), skin pigmentation (37.8%), and peau d'orange appearance (13.3%). Eosinophilia was found in 31 patients (68.9%). Hypergammaglobulinemia was seen in 23/44 (52.3%) and positive antinuclear antibodies in 9 (20%) of the patients. Twentyone of the patients were treated with high-dose methylprednisolone (≥200 mg daily for 3 to 5 consecutive days), and compared with the patients who did not receive this treatment, these patients more frequently experienced relapse before admission, had more extensive involvement, and had a higher rate of hypergammaglobulinemia without fever, but these differences were not statistically significant. Of the 31 patients (68.9%) with follow-up data (for a median of 3.2 years [range 0.2-15.9]), complete remission was achieved in 12 (38.7%) patients, and the accumulative complete remission rate was 44.1% at 5.5 years. No specific baseline characteristics or immunosuppressants were found to correlate with the treatment response. A total of 26 patients underwent both ultrasound and MRI examination, and the Kappa value of the diagnostic results between ultrasound and MRI was 0.91.@*CONCLUSION@#EF is characterized by symmetrical subcutaneous swelling and induration in the limbs, accompanied by eosinophilia and hypergammaglobulinemia. Glucocorticoid is effective for treating EF. Ultrasound examination can identify thickening of subcutaneous fascia for an early diagnosis of EF.

Immune checkpoint inhibitor-induced eosinophilic fasciitis: a case report and literature review / 中华内科杂志

A 58-year-old male patient with angioimmunoblastic T-cell lymphoma developed a rash and skin tightness on the face, limbs, and trunk together with joint stiffness and dysfunction after 6 months of treatment with the programmed cell death protein-1 inhibitor camrelizumab. Laboratory tests revealed progressive eosinophilia over 6 months, with the eosinophil count increasing from 0.07×10 9/L to 3.3×10 9/L. Magnetic resonance imaging showed thickened skin of both forearms, while T 2-weighted imaging showed markedly increased signal intensity within the myofascia. Skin biopsy of the right forearm showed thickened and fibrosed fascia and infiltration of inflammatory cells, including lymphocytes, plasma cells, and eosinophils. The patient was diagnosed with immune checkpoint inhibitor (ICI)-induced eosinophilic fasciitis (EF). After beginning treatment with methylprednisolone (40 mg daily), methotrexate (10 mg/week), and baricitinib (4 mg daily), his symptoms of skin tightness and joint dysfunction significantly improved within 1 month, and his peripheral blood eosinophil count decreased to 0.17×10 9/L. ICI-induced EF is a rare immune-related adverse reaction. To date, only 20 cases have been reported in published foreign literature, and their clinical characteristics are summarized here. The time from ICI treatment to EF was 12 (8,15) months, and the main clinical manifestations included skin involvement ( n=19), joint dysfunction ( n=11), myalgia/muscle weakness ( n=9), and peripheral eosinophilia ( n=16). After treatment, the clinical symptoms of EF improved in 17 patients, and eosinophil counts returned to normal after 3 (1,8) months. EF is a dysfunctional adverse response to ICI therapy. Tumor patients undergoing immunotherapy should be monitored for symptoms of EF. Early treatment is essential for preventing complications.

The incidence and risk factors of lumbodorsal fasciitis in osteoporotic vertebral compression fractures / 中华骨科杂志

Objective:To identify the incidence and risk factors related to lumbodorsal fasciitis in acute osteoporotic vertebral compression fractures (OVCF).Methods:The clinical data of 1182 acute OVCF hospitalized in Zhongda Hospital Southeast University between June 2016 and October 2020 were retrospectively analyzed, including 219 males and 963 females, aged 72.19±9.39 years (range, 45-98 years). The demographics, comorbidity profile, spine trauma, back pain duration, and vertebral fracture number of the OVCF with or without lumbodorsal fasciitis were summarized and compared. The independent risk factors of lumbodorsal fasciitis were identified by binary logistic regression analysis.Results:There were 532 cases of OVCF complicated with lumbodorsal fasciitis among 1,182 patients, and the incidence was 45.01%. The OVCF with fasciitis had higher ratio of males (23.5%, 125/532) than the OVCF without (14.5%, 94/650) fasciitis (χ 2=15.82, P<0.001). The OVCF with fasciitis were aged 74.57±9.21 years and significantly older than the OVCF (aged 70.24±9.60 years) without fasciitis ( t=7.85, P<0.001). The highest proportion of patients with OVCF combined with fasciitis was ≥80 years old (36.1%, 192/532), while most (34.6%, 225/650) of the OVCF without fasciitis were aged 60-70 years (χ 2=56.27, P<0.001). The OVCF with fasciitis had higher ratio of no evident spine trauma (37.0%, 197/532) and multiple vertebral fractures involving ≥3 vertebra (10.5%, 56/532) than the OVCF without fasciitis [26.3% (171/650), 3.2% (21/650); χ 2=17.67, P<0.001; χ 2=40.63, P<0.001]. The ratio of pre-hospital back pain >4 weeks was higher in the OVCF with (20.7%, 110/532) than without (7.4%, 48/650) fasciitis (χ 2=62.46, P<0.001). The OVCF with fasciitis had higher comorbidity of hypertension (52.8%, 281/532), coronary heart disease (14.7%, 78/532), and cerebral infarction (24.8%, 132/532) than the OVCF without fasciitis [42.8% (278/650), 9.9% (64/650), 17.9% (116/650); χ 2=11.85, P<0.001; χ 2=6.42, P=0.011; χ 2=8.56, P=0.003]. The OVCF with fasciitis had higher ratio of two comorbidities (23.7%, 126/532) than the OVCF without fasciitis (16.1%, 105/650) (χ 2=21.15, P<0.001). Binary logistic regression analysis showed significantly higher risk of lumbodorsal fasciitis in males than in females ( OR=1.69, P=0.001), in age group 60-<70、70-<80 and ≥80 years than in <60 years ( OR=2.28, P=0.002; OR=2.64, P<0.001; OR=4.90, P<0.001), in back pain for 2-<4 weeks and >4 weeks than in ≤1 week ( OR=1.70, P=0.005; OR=3.81, P<0.001), and in multiple fractures involving 2 and ≥3 vertebra than in single vertebrae ( OR=1.75, P=0.003; OR=3.36, P<0.001). Conclusion:Up to 45% of acute OVCF have concurrent lumbodorsal fasciitis. Male, aged ≥60 years, pre-hospital back pain ≥2 weeks, and fractures in ≥2 vertebra are independent risk factors of lumbodorsal fasciitis in OVCF.

Reconstrução escrotal após gangrena de Fournier / Scrotal reconstruction after Fournier's gangrene

Introdução: Gangrena de Fournier é uma infecção polibacteriana, geralmente causada por bactérias anaeróbias e aeróbias, sendo caracterizada por fasciite necrosante escrotal e perineal. Seu tratamento é embasado em intervenção cirúrgica com excisão da área necrótica e antibioticoterapia precoces. Diversas são as estratégias de reconstrução do defeito resultante do desbridamento, devendo ser salientado que perdas teciduais maiores do que 50% costumam ser reconstruídas com retalhos. Métodos: Análise retrospectiva da série de casos de reconstrução escrotal após gangrena de Fournier procedidos pelos autores ao longo de 2020, totalizando oito pacientes. Resultados: O retalho mais utilizado foi o fasciocutâneo de coxa, que apresentou taxa de necrose parcial de 14,29%, sem necrose total. Em um dos casos foi possível reconstruir uma uretra esponjosa com músculo grácil sem fistulização, evitando que o paciente fosse submetido a uma uretrostomia definitiva. Quanto às complicações, foi comum a ocorrência de intercorrências menores que necessitaram de procedimentos revisionais simples. Destaca-se a prevalência de 75% de diabetes mellitus em nossa casuística, o que pode ter interferido negativamente no processo cicatricial. Conclusão: A reconstrução escrotal com retalhos é importante para acelerar a cicatrização da ferida proveniente do desbridamento de gangrena de Fournier e para manter o aspecto de bolsa necessário para a termorregulação do testículo. Nossa opção primária foi o retalho fasciocutâneo de coxa, que se mostrou seguro. Pequenas intercorrências foram frequentes nesta série, sem comprometimento do resultado final.

Introduction: Fournier's gangrene is a polybacterial infection, usually caused by anaerobic and aerobic bacteria, characterized by scrotal and perineal necrotizing fasciitis. Its treatment is based on surgical intervention by excision of the necrotic area and early antibiotic therapy. There are several strategies to reconstruct the defect resulting from debridement, and it should be noted that tissue losses greater than 50% are usually reconstructed with flaps. Methods: Retrospective analysis of the series of cases of scrotal reconstruction after Fournier's gangrene performed by the authors throughout 2020, totaling eight patients. Results: The most used flap was thigh fasciocutaneous flap, which presented a partial necrosis rate of 14.29%, without total necrosis. In one of the cases, it was possible to reconstruct a spongy urethra with gracilis muscle without fistulization, preventing the patient from undergoing a definitive urethrostomy. As for complications, the occurrence of minor complications that required simple revision procedures was common. The prevalence of 75% of diabetes mellitus in our series is highlighted, which may have negatively interfered with the healing process. Conclusion: Scrotal reconstruction with flaps is important to accelerate wound healing from Fournier gangrene debridement and to maintain the pouch aspect necessary for testicular thermoregulation. Our primary option was thigh fasciocutaneous flap, which proved to be safe. And minor complications were frequent in this series, without compromising the final result.

Resumen: Introducción: la fascitis o fasciosis plantar es una causa de dolor en el pie, en la cual frecuentemente se encuentran casos resistentes al tratamiento conservador. La cirugía queda reservada para los pacientes que no han respondido a tratamientos conservadores, ondas de choque o infiltraciones con corticosteroides. El objetivo de este trabajo es realizar una revisión sistemática de la literatura disponible y describir una técnica para el tratamiento de la fascitis o fasciosis plantar consistente en el rasgado longitudinal de la aponeurosis plantar asistido con ecografía. Material y métodos: se realizó una búsqueda sistemática de publicaciones previas sobre la tenotomía longitudinal en el tratamiento de la fascitis plantar. Se incluyeron los encabezados de temas médicos o MeSH (Medical subjects headings por sus siglas en inglés), en inglés: Curettage, Tenotomy y Plantar Fasciitis. La búsqueda electrónica incluyó las bases de datos de PubMed, Embase, Cochrane central register of controlled trials, Trip database y National Institute for Health and Care Excellence (NICE por sus siglas en inglés). Se realizó una descripción detallada de la técnica con la intención de que pueda ser reproducida. Conclusión: la tenotomía longitudinal representa una alternativa para el tratamiento de la fascitis plantar. Se basa en la extrapolación del conocimiento en el territorio Aquíleo con una base fisiopatológica de respaldo. Se trata de una técnica no invasiva que se puede realizar de forma ambulatoria y que permitiría la rápida incorporación del paciente a sus actividades. La tenotomía longitudinal podría evitar al paciente someterse a cirugías de mayor envergadura.

Abstract: Introduction: plantar fasciitis or fasciosis is a cause of foot pain with cases resistant to conservative treatment. Surgery is reserved for patients who have not responded to conservative treatment, shock waves, or corticosteroid injections. The aim of this publications is to carry out a systematic review of the available literature and to describe a specific technique for the treatment of plantar fasciosis consisting of the longitudinal tearing of the plantar aponeurosis assisted with ultrasound. Material and methods: a systematic search was carried out for previous publications on longitudinal tenotomy in the treatment of plantar fasciitis. The Medical Subject Headings (MeSH) terms «Curettage¼, «Tenotomy¼ and «Plantar Fasciitis¼ were included. The electronic search included PubMed, Embase, Cochrane central register of controlled trials, Trip database, and National Institute for Health and Care Excellence (NICE) databases. A detailed description of the technique was included with the intention that it can be reproduced. Conclusion: longitudinal tenotomy represents an alternative for the treatment of plantar fasciitis. It is based on the extrapolation of knowledge in the Achilles tendon territory with a supporting pathophysiological basis. It is a non-invasive technique that can be performed on an outpatient basis and that would allow the rapid incorporation of the patient to their activities. Longitudinal tenotomy would prevent the patient from undergoing major surgeries.

Ludwig's angina complicated with a massive necrotizing fasciitis caused by an unusual pathogen: Bacillius spp

Ludwig's angina and necrotizing fasciitis are aggressive infectious manifestations that can present in the cervicofacial region. The severity of these entities depends, up to some extent, to the immunological state of the patient. Diabetes mellitus alters the immune system, allowing maxillofacial infections to progress aggressively. Bacillius spp. is a group of typically innocuous bacteria; however, they can unchain relevant infectious pathologies in immunocompromised patients. The purpose of this study is to describe a case of an uncontrolled diabetic patient with a Ludwig's angina which progressed to a massive necrotizing fasciitis caused by bacillius spp. Explaining the severity of this class of infections and the special attention that should be paid to this type of case; Furthermore, when the culture reveals pathogens that are usually not involved in the development of this class of conditions.

Pulmonary inflammatory myofibroblastic tumor coexisting with lymphangitis carcinomatosis: Mimicking metastatic papillary thyroid carcinoma with nodular fasciitis-like stroma

Inflammatory myofibroblastic tumors (IMTs) are uncommon; intermediate grade soft tissue tumors occurring in young individuals with an uncertain behaviour. The incidence of pulmonary lymphangitis carcinomatosis (PLC) is around 6-8% of all pulmonary metastases. However, PLC due to papillary thyroid carcinoma (PTC) is very uncommon. We present a case of a 26-year-old male, who presented with a solitary left lung nodule on radiological scans. There was also a past history of thyroid surgery done two years back for PTC. Histology revealed a soft tissue tumor reminiscent of IMT. The periphery of the IMT nodule showed metastatic PTC in the form of extensive PLC. In view of this unusual histology, a diagnosis of PTC with nodular fasciitis-like stroma (PTC-NFS) was initially considered. However, molecular studies for anaplastic lymphoma kinase (ALK) gene rearrangement confirmed the diagnosis of IMT. This case highlights the unusual occurrence of tumor-to-tumor metastasis causing diagnostic challenges and also the importance of molecular testing.

Factores de riesgo asociados a evolución desfavorable en el tratamiento de las infecciones de partes blandas

Introducción: Las infecciones de piel y partes blandas (IPPB) son una consulta frecuente y los casos graves conllevan morbimortalidad, por lo que su identificación y manejo precoz es fundamental para mejorar el pronóstico. Objetivo: Identificar los factores de riesgo asociados a una evolución desfavorable y mortalidad en pacientes tratados por IPPB en nuestro centro. Materiales y Método: Se realizó un estudio de casos y controles de una serie consecutiva de 172 pacientes con diagnóstico de IPPB entre enero de 2018 y enero de 2019, se recolectaron variables clínicas, de laboratorio e imagenológicas. Se definió como casos aquellos que requirieron cirugía, ingresaron a una unidad de paciente crítico o fallecieron, y como controles a los pacientes con buena respuesta al tratamiento médico. Resultados: Al realizar el análisis estadístico: la leucocitosis > 12.000 cel/mm3 (OR 6,56; IC 95%; 3,21-13,42), y la PCR > 150 mg/dl (OR 7,79; IC 95%; 3,59-16,91), resultaron ser factores de riesgo para evolución desfavorable. El puntaje LRINEC elevado (25,5% vs. 15,1%, p = 0,1034) y la cirugía tardía al ingreso (31,3% vs. 16,2%, p = 0.2632) fueron más frecuente en los casos de evolución desfavorable, pero sin diferencia significativa. Discusión: El uso de parámetros clínicos, de laboratorio e imágenes es fundamental para un diagnóstico precoz y tratamiento oportuno. Conclusiones: La leucocitosis, la elevación de la PCR y la cirugía tardía son factores de mal pronóstico en IPPB. El puntaje LRINEC aún es controversial por su baja sensibilidad.

Introduction: Skin and soft tissue infections (SSTI) are a frequent consultation and severe cases carry morbidity and mortality, so their early identification and management is essential to improve prognosis. Aim: To identify the risk factors associated with an unfavorable evolution and mortality in patients treated for SSTI in our center. Materials and Method: A case-control study of a consecutive series of 172 patients diagnosed with SSTI between January 2018 and January 2019 was carried out, clinical, laboratory and imaging variables were collected. Cases were defined as those that required surgery, were admitted to a critical patient unit or died, and as controls were patients with a good response to medical treatment. Results: When performing the statistical analysis: leukocytosis > 12,000 cel/mm3 (OR 6.56; 95% CI; 3.21-13.42), and CRP > 150 mg/dl (OR 7.79; 95% CI; 3.59-16.91), turned out to be risk factors for unfavorable evolution. The high LRINEC score (25.5% vs. 15.1%, p = 0.1034) and late surgery on admission (31.3% vs. 16.2%, p = 0.2632) were more frequent in cases of evolution unfavorable but without significant difference. Discussion: The use of clinical, laboratory and imaging parameters is essential for an early diagnosis and timely treatment. Conclusions: Leukocytosis, elevated CRP, and late surgery are poor prognostic factors in SSTI. The LRINEC score is still controversial due to its low sensitivity.

Influencia de la densidad de energía de ondas de choque focalizadas en el tratamiento de la fascitis plantar / Influence of energy density on the effectiveness of the treatment of plantar fasciitis with focused extracorporeal shock waves

Resumen La fascitis plantar (FP) es una patología frecuente e invalidante que puede tratarse con ondas de choque focalizadas. El objetivo principal del estudio fue valorar la eficacia del tratamiento con ondas de choque focalizadas en la FP según la densidad de energía utilizada. Se incluyeron 82 pacientes con diagnóstico clínico de FP que fueron asignados mediante muestreo aleatorio simple a dos grupos de tratamiento: densidad de energía media- alta (0,59mJ/mm2) y densidad de energía media-baja (0,27mJ/mm2). Se evaluaron el dolor y la funcionalidad, mediante las escalas EVA (Escala Visual Analógica) y AOFAS (American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale) respectivamente, al inicio del estudio (consulta base), y al primer, tercer y sexto mes tras el tratamiento. Por último, se evaluó el grado de satisfacción de los pacientes mediante la escala de Roles y Maudsley. Se compararon los resultados de las escalas en las revisiones posteriores al tratamiento, obteniéndose significación estadística para las variables principales del estudio (dolor y funcionalidad) en cada grupo de intervención. Aunque los niveles de dolor y la funcionalidad mejoraron en ambos grupos de estudio, se obtuvo una respuesta analgésica y funcional mayor y más precoz en el grupo tratado con densidad de energía media-alta.

Abstract Plantar fasciitis (FP) is a frequent and disabling condition that can be treated with focused extracorporeal shock waves. The main objective of this study was to assess the effectiveness of focused extracorporeal shockwave treatment in FP according to the energy density used. Eighty-two patients with a clinical diagnosis of FP were included and assigned, by simple random sampling, to two treatment groups: medium-high energy density (0.59mJ/mm2) and low-medium energy density (0.27mJ/mm2). Pain and functionality were assessed using the VAS (Visual Analogical Scale) and AOFAS (American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale) scales, respectively, at the start of the study (baseline consultation), and at the first, third and sixth month post-treatment. Finally, the degree of patient satisfaction was evaluated using the Roles and Maudsley score. The results of the scales in the post-treatment reviews were compared, and statistical significance was obtained for the main study variables (pain and functionality) in each intervention group. Although pain levels and functionality improved in both study groups after treatment, a greater and earlier analgesic and functional response was obtained for the medium-high energy density group.

Cervical Necrotizing Fasciitis: An Uncommon Fulminant Disease Entity

Cervical necrotizing fasciitis is an uncommon fulminant disease of single or polymicrobial infectious origin characterized by rapid necrosis of the subcutaneous tissue and fasciae. The disease has high mortality rate. Early identification, timely surgical debridement, broad spectrum antibiotic therapy, aggressive wound care and intensive medical care of the patient are of paramount importance for better prognosis. We present a case report and review of literature of cervical necrotizing fasciitis with a thorough insight into its epidemiology, etiology, pathogenesis, diagnosis and management.

Graft versus host disease-related eosinophilic fasciitis: cohort description and literature review

Abstract Background: Chronic graft versus host disease (cGVHD) simulating eosinophilic fasciitis (EF) is an underdiagnosed and challenging complication due to the lack of knowledge about its pathogenesis, refractoriness to traditional immunosuppressive agents and their negative impact on the physical function and quality of life. The aim of this study is to describe the clinical-biological characteristics and response to treatment of a case series and to provide a comprehensive literature review on cGVHD related EF involvement. Methods: Prospective observational study to describe the clinical and diagnostic evaluation characteristics of patients with EF-like follow-up as part of our multidisciplinary cGVHD consultations. In addition, the literature on joint and/or fascial musculoskeletal manifestations due to cGVHD was comprehensively reviewed. Results: 118 patients were evaluated in multidisciplinary cGVHD consultations, 39 of whom (33%) developed fasciitis. Notably, 11 patients had isolated joint contractures without sclerotic skin. After a median of three lines of treatment, the vast majority of patients achieved some degree of response. 94 potentially eligible articles were identified by the search strategy, with 17 of them, the majority isolated case reports, making the final selection. The validated staging scales used for the assessment were the Joint and Fascial Score and the Photographic Range of Motion. Conclusion: Fascial/articular involvement needs to be recognized and evaluated early. To our knowledge, our cohort is the second largest series to have been reported. Literature addressing fascial/joints complications related to cGVHD is scarce. The search for new biomarkers, the use of advanced imaging techniques and multidisciplinary approach may help improve the prognosis of patients with cGVHD.
