Research progress in diagnosis and treatment of scrotal masses / 中国基层医药

Scrotal mass is a common problem in the outpatient department of urology, accounting for 1% of all emergency patients. The diagnosis of scrotal masses is challenging due to the overlapping symptoms and signs of various scotal masses. Failure to correctly identify and treat scrotal masses, such as testicular torsion, testicular cancer, varicocele, and hydrocele, may lead to infertility, testicular loss, or even death. Misdiagnosis or missed diagnosis of scrotal masses may result in infertility, testicular loss, or even death. Therefore, we must maintain a high degree of vigilance and accurately identify scrotal masses that may affect life and testicular function. A full understanding of the manifestations and differences of various scrotal masses can help clinicians make accurate diagnoses and provide optimal treatment plans. The most critical aspect is to exclude emergency situations that may endanger life or testicular function, such as testicular torsion, testicular cancer, and necrotizing fasciitis, which require immediate medical attention. Scrotal ultrasonography is the best method for distinguishing scrotal masses based on their origin. Magnetic resonance imaging is the best tool for diagnosing scrotal hematoma. However, good clinical judgment and decision-making are still the most important factors for successful treatment of scrotal masses. The purpose of this article is to describe correct evaluation methods for scrotal masses and identify potential conditions that may threaten testicular survival, enabling accurate pathological diagnosis, evaluation, and treatment plans for each scrotal mass.

Emerging infection: streptococcal toxic shock-like syndrome caused by group B Streptococcus (GBS), Streptococcus agalactiae

ABSTRACT Streptococcus agalactiae or Group B Streptococcus (GBS) infections are commonly associated with infections in neonates and pregnant women. However, there has been a rising incidence in nonpregnant adults. The risk of GBS infection in nonpregnant adults is increased for patients of advanced age and those with underlying medical conditions such as diabetes mellitus and cancer. We present a 77-year-old female with type-2 diabetes mellitus, hypertension, and bilateral foot ulcers that presented in probable septic shock with necrotic foot ulcers and necrotizing fasciitis and underwent bilateral lower limb amputations. The patient fulfilled the Streptococcal Toxic Shock Syndrome (STSS) criteria as defined by The Working Group on Severe Streptococcal Infections. These criteria were created for group A Streptococcus (Streptococcus pyogenes). Our patient fulfilled the Working Group's criteria, except that the blood culture was positive for group B Streptococcus (Streptococcus agalactiae). Numerous studies demonstrate the importance of early detection and antibiotic treatment for GBS infections in general and early surgical management for necrotizing soft tissue infections (NSTIs) such as necrotizing fasciitis.

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.

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.

Uso de la membrana amniótica como material de apósito en paciente con fascitis necrotizante: A propósito de un caso

Introducción: La fascitis necrotizante es una infección grave que involucra la piel, el tejido celular subcutáneo y las fascias superficiales-profundas, progresa muy rápidamente y si no se trata a tiempo puede causar la muerte. Reporte de caso: Presentamos el caso de una paciente adulta con antecedentes de anemia, a quien se le diagnosticó fascitis necrosante de origen odontogénico, por lo que fue intervenida quirúrgicamente y se realizó un drenaje intraoral y extraoral más escarectomía. Además, se le administró tratamiento farmacológico (antibióticos intravenosos) y se colocó una membrana amniótica como material de apósito para reconstruir la superficie hemorrágica dejada por la fascitis necrotizante. 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.

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.

Retrospective analysis of treatment experience in 25 cases of lower extremity necrotizing fasciitis / 中国医师进修杂志

Objective:To retrospectively analyze the treatment of 25 cases of lower necrotizing fasciitis.Methods:A total of 25 patients with lower limb necrotizing fasciitis (13 males and 12 females), with mean age 63 years old (48-75 years old) in Dalian Municipal Central Hospital from September 2016 to December 2020. After admission, the patient′s general physical condition was strictly evaluated, the relevant preoperative examination was improved, and the necrotizing fasciitis laboratory risk index (LRINEC) score was performed. In the absence of surgical contraindication, multiple debridement was performed, leaving the necrotic tissue removed for general bacterial culture and drug sensitivity test in parallel. After debridement, eight patients showed a large area of skin necrosis, and amputation was selected. The other 17 patients chose limb protection treatment after debridement, and adopted debridement and free skin grafting. After surgery, patients were encouraged to strengthen rehabilitation exercise to restore limb function to the maximum extent.Results:With followed up 0.6 to 3.0 years, with an average of 1.8 years. Methods include outpatient return visit, WeChat contact or telephone inquiry. The skin survived in 17 patients with mean healing time (27.5 ± 6.9) d. Eighteen patients were multiple bacterial infections and seven patients were single bacterial infections. All patients had no joint dysfunction caused by scar contracture, and reinfection in the skin grafting area.Conclusions:Necrotizing fasciitis requires early diagnosis and early treatment, with correct choice of treatment method is closely related to the patient′s prognosis.

Infective characteristics of Fournier gangrene and evaluation of effect of negative pressure wound therapy / 中华创伤杂志

Objective:To summarize the infective characteristics of Fournier's gangrene (FG) and evaluate the effect of negative pressure wound therapy (NPWT).Methods:A retrospective case control study was conducted to analyze the clinical data of 31 patients with FG admitted to Peking University First Hospital from May 2010 to September 2020, including 29 males and 2 females, aged 21-78 years [(55.2±2.0)years]. A total of 29 patients were caused by infectious diseases of the perianal and urinary system, and the rest two patients were caused by vulvar infection and retroperitoneal abscess. A total of 23 patients were treated with NPWT (Group A) and 8 patients were treated with conventional dressing (Group B). Characteristics of pathogen, drug-resistance rate, medical treatment and prognosis for all patients were summarized. The hospitalization duration, numbers of operation and wound healing time were compared between two groups.Results:Monomicrobial infection was identified in 14 patients, while polymicrobial infection in 15 patients, fungal infection in 1 and culture-negative in 1. Escherichia coli, Enterococcus faecalis, Enterococcus faecium, Klebsiella pneumoniae and Staphylococcus haemolyticus were the most common pathogenic bacteria. The resistance rate of gram-negative bacilli to third-generation cephalosporins was 37%. Staphylococcus haemolyticus were methicillin-resistant Staphylococcus. The carbapenem antibiotics combined with vancomycin antibiotics were used for all patients as the empirical anti-infection treatment. Three patients died, and the rest 28 patients were followed up for 3 to 12 months [(10.8±2.6)months] after discharge. All the wounds were healed well without recurrence. In Group A and Group B, the hospitalization duration was (37.4±15.0)days and (47.0±16.0)days, respectively ( P>0.05); the number of operation was 3(3, 6) times and 13(4, 17)times, respectively ( P<0.05); the wound healing time was (38.9±17.8)days and (61.8±14.2)days, respectively ( P<0.05). Conclusions:Enterobacteriaceae, Enterococcus and Staphylococcus haemolyticus are the most common pathogenic bacteria for FG, among which the proportion of drug-resistant bacteria is relatively high. NPWT is an effective adjuvant therapy for wound management with reduced operation times and short wound healing time compared to conrentional method.

Severe bacterial skin infections

Abstract The severe bacterial diseases discussed herein are those that present dermatological lesions as their initial manifestations, for which the dermatologist is often called upon to give an opinion or is even the first to examine the patient. This review focuses on those that evolve with skin necrosis during their natural history, that is, necrotizing fasciitis, Fournier gangrene, and ecthyma gangrenosum. Notice that the more descriptive terminology was adopted; each disease was individualized, rather than being referred by the generic term "necrotizing soft tissue infections". Due to their relevance and increasing frequency, infections by methicillin-resistant Staphylococcus aureus (MRSA) were also included, more specifically abscesses, furuncle, and carbuncle, and their potential etiologies by MRSA. This article focuses on the epidemiology, clinical dermatological manifestations, methods of diagnosis, and treatment of each of the diseases mentioned.

Diagnóstico e tratamento da síndrome do choque tóxico estreptocócico em unidade de terapia intensiva pediátrica: relato de caso / Diagnosis and treatment of streptococcal toxic shock syndrome in the pediatric intensive care unit: a case report

RESUMO Dentre as infecções causadas por Streptococcus β hemolyticus do grupo A de Lancefield, talvez a síndrome do choque tóxico seja a mais grave, com alto índice de mortalidade. A semelhança clínica com outras formas de choque, principalmente séptico, pode, muitas vezes, confundir o avaliador e interferir na escolha da terapêutica mais adequada. Esse relato tem o objetivo de auxiliar seus leitores quanto à necessidade de adicionar tal síndrome como diagnóstico diferencial, frente a quadros de choque, principalmente aqueles que não apresentam manifestações clínicas bem definidas. Para isso, apresentamos o quadro de um lactente com sintomas gripais comuns, que evoluiu rapidamente com exantema, rebaixamento do nível de consciência, sinais clínicos e laboratoriais de choque, com necessidade de suporte intensivo. Além de culturas indicando o agente etiológico, o aparecimento de exantema e fasciíte necrosante levou ao diagnóstico, mas, em menos de 50% dos casos temos sinais clínicos clássicos dessa entidade. As penicilinas em terapia combinada com aminoglicosídeos ainda são a terapia de escolha e possuem alto nível de evidência. Apesar da gravidade a evolução foi satisfatória.

ABSTRACT Among the infections caused by Streptococcus β hemolyticus from the Lancefield serogroup A, toxic shock syndrome is perhaps the most severe, and its mortality rate is high. Its clinical similarity to other forms of shock, especially septic shock, can often confuse the evaluator and interfere with the selection of the most appropriate therapy. This report aims to inform readers of the need to add this syndrome as a differential diagnosis in cases of shock, especially those with no well-defined clinical manifestations. For this purpose, we present the case of an infant with common flu-like symptoms who progressed rapidly with a rash, a reduced level of consciousness and clinical and laboratory signs of shock that required intensive support. In addition to cultures indicating the etiological agent, the appearance of exanthema and necrotizing fasciitis led to the diagnosis. However, less than 50% of cases present classic clinical signs of this entity. Penicillins combined with aminoglycosides are still the therapy of choice and are supported by a high level of evidence. Despite the severity of this patient's presentation, the progression was satisfactory.

CONCLUSION: Assistance to patients with Fournier Syndrome is poorly standardized, resulting in high mortality rates. Development of specific protocols is necessary.

Comprehensive treatment on ten patients with perianal necrotizing fasciitis / 中华烧伤杂志

Ten patients with perianal necrotizing fasciitis were admitted to our department from June to December 2016. There were 8 men and 2 women among the patients, aged 42 to 69 years. Early and complete debridement surgery and comprehensive supportive treatment during perioperative period were carried out to quickly stabilize the patient′s overall condition, and wounds were sutured directly or repaired with autologous scalps and or adjacent local random flaps. After debridement, wound areas ranged from 10 cm×8 cm to 54 cm×21 cm, and area of the flap was about 8 cm×5 cm. The donor site of flap was sutured directly. After the operation, all skin grafts and the flap survived, and wounds of all patients healed. During follow-up of six months to one year, there was no recurrence of perianal necrotizing fasciitis, and functions of the involved lower extremities didn′t be influenced.

Las infecciones necrosantes de partes blandas constituyen un grupo heterogéneo de afecciones, poco frecuentes pero potencialmente letales, caracterizadas por la infección de la piel, el tejido celular subcutáneo y el músculo. La fascitis necrosante es una rara enfermedad. En Cuba no existen estudios de incidencia. Su etiología es generalmente polimicrobiana. El Streptococcus pyogenes es el germen más frecuente. Las toxinas bacterianas, mediante su actividad citopática y protrombótica, son las responsables de la necrosis tisular. Su curso clínico no es uniforme, los médicos solo logran hacer un diagnóstico inicial correcto del 15 % al 30 % de los casos. Si los signos y los síntomas iniciales se detectan a tiempo su índice de mortalidad puede lograr reducirse hasta el 12 %. El objetivo de este trabajo es hacer una revisión del tema y presentar los criterios actuales de diagnóstico y tratamiento.

Necrotizing lesions in soft tissues are a heterogeneous type of illnesses. infrequent but potentially fatal, characterized by skin infection, of the subcutaneous tissue and muscle. Necrotizing fasciitis is an unsual disease. There no incidence studies in Cuba. Its etiology is generally polymicrobial. Streptococcus pyogenes is the most frequent germ. Bacterial toxins, through its cytopathic and thrombotic activity, are responsible of tissue necrosis. Its clinical development is not uniform, doctor only achieve an initial correct diagnosis in the 15 to 30 % of the cases. If initial sings and symptoms are identified its mortality may be reduced to 12%. The objective of this work is to review the topic and present the current diagnosis and treatment criteria.

Técnica ahorradora de tejidos con injertos de piel parcial: sistema Meek versus sistema convencional mallado. Reporte de caso / Tissue sparing technique using partial skin transplantation: Meek technique versus conventional mesh technique. A case report

La técnica Meek es útil en pacientes con sitios donantes limitados, ya que es relativamente eficiente en cuanto a la expansión de la piel; llegando a expandirse hasta 9 veces en comparación al tamaño original, se realizó la evaluación de la cicatrización entre dos técnicas de expansión de tejidos de 1:3 veces entre la técnica Meek y la técnica mallado convencional. Cabe destacar que, con los avances de la bioingeniería, la técnica Meek se integra como un método completo para el tratamiento de autoinjertos. Presentamos un caso de un paciente varón de 34 años con una enfermedad infecciosa poli bacteriana "fascitis necrotizante"; con pérdida de tejidos que comprometen el tórax, abdomen y región inguino perineal, con un 14% de superficie corporal total comprometida. En la valoración cualitativa con la escala de Vancouver y POSAS se observaron mejores resultados de cicatrización con la técnica Meek.

The Meek technique is useful in patients with limited donor sites. It is a relatively efficient technique due to its ability to expand the skin up to nine times its original size. Scarring was assessed using two tissue expansion techniques, i.e. the Meek technique and the conventional mesh technique, which achieved an expansion ratio of 1:3. It should be noted that, with advances in bioengineering, the Meek technique is integrated as a complete method for autografting.1,2 We present the case of a 34-year-old male patient with a polymicrobial infectious disease called "necrotizing fasciitis". He had lost tissues of the thorax, abdomen and inguinal-perineal region, affecting 14% of his total body surface area. A qualitative assessment using the Vancouver scale and the Patient Objective Scar Assessment Scale (POSAS) showed better scarring results with the Meek technique
