Introduction: Fournier's gangrene is currently defined as a specific form of synergistic, rapid, progressive and multibacterial necrotizing fasciitis, which mainly affects the muscular fascia of the perineal, genital, or perianal region and even the abdominal wall; with genitourinary, colorectal, or idiopathic starting point. All of this, accompanied by skin gangrene in these areas due to thrombosis of subcutaneous blood vessels. Objectives: To describe the epidemiological and surgical characteristics of the sequelae patients of Fournier's disease in the Plastic Surgery Unit of the Hospital de Clínicas in a period of 2 years. Materials and methods: Observational, descriptive, cross-sectional, temporally retrospective, case series type study. The type of sampling was non-probabilistic at convenience. Eighteen sequelae patients of Fournier's disease reconstructed in the Plastic Surgery Unit of Hospital de Clínicas between 2020 and 2021 are presented. Results: During the study period, 395 surgeries were performed in the Plastic Surgery Service of the Hospital de Clínicas, of which 18 patients underwent surgery for sequelae of Fournier's disease, which represents 5% of the total. Regarding demographic variables, age ranged between 37 and 85 years with greater impact in the sixth decade of life with an average of 61 years. 94% of the patients were male; 89% of the patients had type 2 diabetes mellitus as an underlying pathology, followed by obesity in 72% and high blood pressure in 56% of cases; In 83% of the cases, the scrotal region was affected, followed by the perineal region in 56% of the patients and the penis in 50% of the cases. The most frequently used reconstructive technique was flaps in 10 patients, followed by skin grafting in 8 patients, and primary closure in 6 patients. It is worth mentioning that in some patients several reconstructive techniques were used following the concept of reconstruction by sub- anatomical units, among the flaps the most used were the medial femoral circumflex perforator flap (gracilis perforator) with 50% of the cases followed by the fasciocutaneous transposition flap of the internal pudendal with 30%, and finally the fasciocutaneous advancement flap with 20% (Table 3). The average hospital stay was 3 days, with a minimum of 1 day and a maximum of 5 days postoperatively. Suture dehiscence was reported as a complication in 3 patients; no complications were observed in 77% of the cases. Conclusion: The sequelae of Fournier's disease undergoing surgeries represent 5% of the total number of surgeries performed in our Service, they are more prevalent in the sixth decade of life, it affects more males with type 2 diabetes mellitus as the underlying pathology, the reconstructive techniques used in the sequelae are variable according to the anatomical regions affected and can range from primary closure to the use of flaps for repair.

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.

Aesthetic Reconstruction of Scrotum after Founiers Gangrene using Laterally based Medial Thigh Fasciocutaneous Flap

Introduction : Fournier抯 Gangrene is a rapidly progressive necrotising faciitis affecting the genital region, perineum, perianal region and the abdominal wall. It can have an adverse effect on the functional and psychological aspects of the patient. Many flaps are available for the defect coverage. Aim : The aim of this prospective study was to analyse the effectiveness of laterally based medial thigh flap for scrotal reconstruction. This is a fasciocutaneous flap just below the Scrotum which covers moderate to large sized scrotal defects successfully. Methods and Materials : This study was done at a teaching hospital in South India on patients with major scrotal defects secondary to Fournier抯 Gangrene. Ten patients with major scrotal defects secondary to Fournier抯 gangrene were subjected to reconstruction of scrotum by medial thigh fasciocutaneous flap. Results and Conclusions : All ten flaps survived and provided a durable and aesthetic cover for exposed testes. Only one flap had necrosis of distal 2cm, which was successfully managed by secondary suturing. The donor areas were primarily covered with placement of a small graft near the base of the flap, which healed well with an inconspicuous scar. In conclusion, the laterally based medial thigh fasciocutaneous flap provides excellent closure for extensive scrotal skin loss. It is a robust flap, easy to mobilise, rarely undergoes necrosis, provides a sensate cover with excellent aesthetic results. The technique is simple, less time consuming and can be easily incorporated by plastic Surgeons and General Surgeons

Implementación artesanal del sistema VAC en pacientes con Gangrena de Fournier: serie de casos

La fascitis necrosante es una infección de los tejidos blandos profundos que provoca la destrucción progresiva de la fascia muscular y subcutánea. Una de sus presentaciones es la Gangrena de Fournier (GF) para el cual el diagnóstico debe de ser preciso y asociado a desbridamiento quirúrgico precoz y antibioticoterapia de amplio espectro. Si existe retraso del manejo, la repercusión en el pronóstico es negativa. Entre las opciones actuales para el tratamiento destaca una técnica para mejorar la limpieza y granulación del área cruenta mediante el uso del dispositivo tecnológico y el sistema de cierre asistido por vacío (VAC). Describimos el manejo y la técnica de la terapia VAC implementado artesanalmente en una serie de casos de pacientes masculinos con diagnóstico de GF, en respuesta a los escasos recursos económicos de los pacientes que generalmente son afectados en nuestro medio; proponiendo una opción más económica, segura y replicable para nuestro entorno.

Necrotizing fasciitis is a deep soft tissue infection that causes progressive destruction of the muscle fascia and subcutaneous . One of its presentations is Fournier's Gangrene (FG) for which the diagnosis must be accurate and associated with early surgical debridement and broad-spectrum antibiotic therapy. If management is delayed, the impact on prognosis is negative. Current treatment options include a technique to improve cleaning and granulation of the cruciate area using a technological device and the vacuum assisted closure system (VAC). We describe a handmade technique of VAC therapy implemented in a series of cases of male patients diagnosed with FG, in response to the scarce economic resources of patients who are generally affected in our environment; proposing a more economical, safe and replicable option for our environment.

The Osseous Pathology of Purpura Fulminans in a TwoYear-Old Child: A Case Report

@#Purpura fulminans (PF) is a severe clinical manifestation of Neisseria meningitides infection that is associated with high mortality rates in children. Survivors are frequently left with debilitating musculoskeletal sequelae. There is a paucity of reports on the musculoskeletal pathology of purpura fulminans. We report on a 2-year-old boy with purpura fulminans due to meningococcemia. The child developed distal gangrene in both the upper and lower limbs. Amputations were done for both lower limbs. Histological examination of the amputated specimens showed an inflammatory process and features of osteonecrosis. The latest follow-up at the age of 6 years showed a right knee valgus due to asymmetrical growth arrest of the proximal tibia. PF and its complications are challenging to treat and may require a multidisciplinary approach to improve patient’s functional ability.

Varicella gangrenosa: A rare chickenpox complication

Varicella gangrenosa is a rare but life-threatening dermatological complication of infection with varicella-zoster virus. A healthy 37-year-old male who had been diagnosed with varicella 20 days back was admitted to our hospital with complaints of fever and painful necrotic skin lesions. Physical examination revealed multiple round to oval ulcers covered with eschar predominantly over arms, lower limbs, back of trunk and flanks. Streptococcus pyogenes and Staphylococcus aureus grew in wound culture. Biopsy revealed ulceration and necrosis of epidermis, and edema, hemorrhage and granulation tissue formation involving the dermis and subcutaneous tissue. The patient was treated with acyclovir - parenteral followed by oral, antibiotics and supportive measures. The lesions healed and he was discharged after 20 days. We report this case to draw attention to the fact that varicella gangrenosum, even though a rare complication, may occur in the lesions of chicken pox and that the survival of patient depends on early diagnosis and aggressive treatment

Symmetrical peripheral gangrene in a chronic kidney disease patient on hemodialysis

Symmetrical peripheral gangrene (SPG) is a rare but well-described condition characterized by ischemic changes in the distal limbs with preserved flow in the major vessels. It results from thrombosis of the microcirculation resulting from a complex interplay of infectious and non-infectious factors. Often described as a complication of disseminated intravascular coagulation (DIC), it has got multiple aggravating factors. Timely recognition and management is important as significant residual disability is noted in surviving patients. Here, we describe a patient with chronic kidney disease on maintenance hemodialysis presenting with SPG associated with spontaneous bacterial peritonitis and DIC. She had multiple aggravating factors such as hypotension, use of inotropes, and renal failure. As there were no evidence-based guidelines and since the general condition of the patient was poor, she was managed with supportive care.

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.

Unusual clinical presentations of scrub typhus, a neglected tropical disease: A case series from north India

Background & objectives: Scrub typhus is a neglected tropical disease common in Asia and Africa. It usually presents with non-specific symptoms like fever, rashes, and lymphadenopathy. It has a varying range of clinical picture that often leads to misdiagnosis and initiation of non-specific treatment. This disease is thus associated with high morbidity and mortality. We aim to highlight the uncommon presentations of this common disease to create awareness regarding the unusual presentations of scrub typhus. Methods: This prospective study was performed over a period of two months enrolling eleven adult patients with serological evidence of anti-scrub typhus IgM antibodies. Results: All enrolled 11 cases [5 males (45.5%) and 6 females (54.5%)] were positive for anti-ST IgM antibodies and negative for other tested microbial agents. 7/11 (63.6%) patients were admitted with a clinical diagnosis of acute encephalitis syndrome (AES as per standard WHO definition), 3/11 (27.3%) patients presented with jaundice and 1/11 (9.1%) patients presented with rashes. Two out of 7 (28.6%) AES cases had developed peripheral gangrene of extremities. Interpretation & conclusion: Scrub typhus is a common tropical disease that can have various unusual clinical presentations like meningoencephalitis, vasculitis, acute kidney injury, jaundice, MODS. It closely mimics other infective etiologies making its diagnosis difficult. A high index of suspicion and clinical awareness is required in clinical practice to identify the different presentations of this disease so that early treatment can be initiated to reduce morbidity and mortality associated with this disease.

The role of hyperbaric oxygen therapy in Fournier's Gangrene: A systematic review and meta-analysis of observational studies

ABSTRACT Purpose: Management of Fournier's Gangrene (FG) includes broad-spectrum antibiotics with adequate surgical debridement, which should be performed within the first 24 hours of onset. However, this treatment may cause significant loss of tissue and may delay healing with the presence of ischemia. Hyperbaric oxygen therapy (HBOT) has been proposed as adjunctive therapy to assist the healing process. However, its benefit is still debatable. Therefore, this systematic review and meta-analysis aimed to evaluate the effect of HBOT as an adjunct therapy for FG. Materials and Methods: This study complied with the Preferred Reporting Items for Systematic Reviews and Meta-analyses protocol to obtain studies investigating the effect of HBOT on patients with FG. The search is systematically carried out on different databases such as MEDLINE, Embase, and Scopus based on population, intervention, control, and outcomes criteria. A total of 10 articles were retrieved for qualitative and quantitative analysis. Results: There was a significant difference in mortality as patients with FG who received HBOT had a lower number of deaths compared to patients who received conventional therapy (Odds Ratio 0.29; 95% CI 0.12 - 0.69; p = 0.005). However, the mean length of stay with Mean Difference (MD) of -0.18 (95% CI: -7.68 - 7.33; p=0.96) and the number of debridement procedures (MD 1.33; 95% CI: -0.58 - 3.23; p=0.17) were not significantly different. Conclusion: HBOT can be used as an adjunct therapy to prevent an increased risk of mortality in patients with FG.

EFFECTS OF HYPERBARIC OXYGEN THERAPY IN PATIENT WITH ACUTE UPPER LIMB FINGER GANGRENE WITH COVID-19

The COVID-19 pandemic (Corona Virus Diseas) was caused by a new beta coronavirus in early 2020, also called Severe Acute Respiratory Syndrome (SARS-CoV-2). Predilection sites of virus entry are the lungs, intestines, blood vessels, kidney, and adipose tissue cells are the virus reservoir. The virus causes a violent reaction of in?ammatory cytokines - cytokine storm, activation of coagulation and formation of thrombin. The initial coagulopathy of COVID-19 is manifested by a pronounced disorder of D-dimer and ?brin/?brinogen degradation products, while abnormalities in prothrombin time, partial thromboplastin time and platelet count are relatively rare at the onset of the disease. Later, the phenomenon of thrombotic microangiopathy occurs, which is a consequence of in?ammation of the blood vessels endothelium. In severe cases of infection, thromboembolism or acute thrombosis of peripheral blood vessels may occur. The paper presents a case of a patient with COVID-19 infection in whom, in addition to the usual clinical picture of the disease with changes in lung parenchyma (bilateral pneumonia), thrombosis of the a. radialis and a. ulnaris of the left hand developed, and ?fteen days after the infection development, the development of gangrene of the distal articles II, III and IV of the ?nger occurs. In addition to therapy used according to the national guide to COVID-19, hyperbaric oxygen therapy (HBOT) was used. The effect of this therapy was used to increase vascular permeability and create factors that affect angiogenesis and improve blood ?ow in the ischemic region. HBOT also affected the demarcation of necrotic from healthy tissue, and stimulated wound healing. After two sessions of HBOT treatment, there was a complete restitution of blood ?ow with full function of the left hand and all its ?ngers.

Aplicação do ultrassom point of care e relevância da anatomia na fasciite necrosante / Application of point of care ultrasound and relevance of anatomy in necrotizing fasciitis

Introdução: O ultrassom tem sido utilizado na atualidade na medicina intensiva. A fasciite necrosante quando não diagnosticada e tratada rapidamente apresenta progressão rápida e alta mortalidade. O objetivo é apresentar a importância da anatomia na fasciite necrosante e o uso do ultrassom no diagnóstico precoce. Métodos: Apresentou-se a aplicação do ultrassom point of care e a relevância da anatomia na fasciite necrosante. Resultados: As comunicações anatômicas entre as fáscias das regiões escrotal, perineal, peniana e abdominal permitem a disseminação do processo infeccioso decorrente da gangrena de Fournier para as regiões adjacentes. O ultrassom possibilitou o diagnóstico precoce na fasciite necrosante. Conclusão: As comunicações entre as fáscias das regiões escrotal, perineal, peniana e abdominal contribuíram para a progressão do processo infeccioso decorrente da gangrena de Fournier e o ultrassom possibilitou o diagnóstico precoce.

Introduction: Ultrasound is currently being used in intensive care medicine. When not diagnosed and treated quickly, necrotizing fasciitis has a rapid progression and high mortality. The objective is to present the importance of anatomy in necrotizing fasciitis and the use of ultrasound in early diagnosis. Methods: The application of point-of-care ultrasound and the relevance of anatomy in necrotizing fasciitis were presented. Results: The anatomical communications between the fasciae of the scrotal, perineal, penile and abdominal regions allow the spread of the infectious process resulting from Fournier's gangrene to the adjacent regions. Ultrasound enabled early diagnosis of necrotizing fasciitis. Conclusion: Communications between the fasciae of the scrotal, perineal, scrotal, penis and abdominal regions contributes to the progression of the infectious process resulting from Fournier gangrene and ultrasound permitted earlier diagnose.

Symmetrical Peripheral Gangrene – A Rare Clinical Manifestation of Hodgkin’s Lymphoma

Symmetrical peripheral gangrene (SPG) is a cutaneous manifestation of a wide array of infective and noninfective etiological factors and occurs due to hypoxemia, vasoconstriction, primary endothelial damage and/or decreased cardiac output. It is a devastating complication of underlying septicemia and disseminated intravascular coagulation (DIC) with a high mortality rate and commonly requiring amputation of the affected limb in those who survive. We here describe a case that presented with fever, cough, blackish discoloration of fingers and generalized lymphadenopathy. Investigation revealed anemia, leukocytosis, coagulopathy and positive D-dimer test. Fine-needle aspiration cytology (FNAC) showed evidence of Hodgkin’s lymphoma.

Related factors of intestinal necrosis caused by midgut volvulus in neonates / 中国新生儿科杂志

Objective:To study the characteristics and related factors of neonatal intestinal necrosis caused by midgut volvulus.Methods:We retrospectively analyzed the clinical data of neonates with midgut volvulus who were admitted to Guangzhou Women and Children's Medical Center, from January 2009 to December 2019 and confirmed by surgery. The cases with intestinal necrosis belong to the intestinal necrosis group, and those without intestinal necrosis, the non-intestinal necrosis group which was randomly sampled at a ratio of about 4∶1 to the number of cases in the intestinal necrosis group. The two groups were compared in terms of personal history, age of onset, initial symptoms, vital signs within 2 h after admission, time from symptom onset to operation, clinical outcome, laboratory indicators within 2 h after admission, etc. Multivariate Logistic regression analysis was used to screen the related factors of intestinal necrosis in midgut volvulus. The effective warning indexes are screened by receiver operating characteristic (ROC) curve.Results:(1) Among 231 cases of midgut volvulus, 21 cases (9.1%, 21/231) had intestinal necrosis at the time of operation, 87 cases were included in the non-intestinal necrosis group. (2) The levels of heart rate within 2 h after admission, mean arterial pressure, WBC, C reactive protein (CRP), blood glucose and potassium in intestinal necrosis group were significantly higher than those in non-intestinal necrosis group ( P<0.05). Admission days of age, hemoglobin, serum albumin, serum sodium, pH and BE levels were significantly lower than those in the group without intestinal necrosis ( P<0.05). (3) In the multivariate analysis, increased heart rate, mean arterial pressure, serum CRP, and decreased serum sodium, serum albumin, and pH levels were predictors related to intestinal necrosis in patients with midgut volvulus. (4) The area under the ROC curve (AUC) of CRP was 0.883, the cutoff value was 9.88 mg/L, the sensitivity was 76.2%, and the specificity was 94.3%. The ROC curve of serum albumin was 0.792, the cut-off value was 36.65 g/L, the sensitivity was 70.1%, and the specificity was 94.3%. Conclusions:Heart rate, mean arterial pressure, increased CRP, decreased serum sodium, serum albumin and pH are helpful to predict whether intestinal necrosis occurs in midgut volvulus, and CRP > 9.88 mg/L and serum albumin < 36.65 g/L are likely warning indicators.

Foreign body induced penile gangrene in mentally challenged patient - A case report

Penile gangrene is extremely rare. It spreads very rapidly to surrounding structures and have high mortality rate. Its etiology can be infectious, traumatic or vasculogenic. Precipitating factors can be elicited with careful history and examination. Its management depends upon clinical presentation, which includes serial debridement, partial or total penectomy and treatment of underlying pathology[1]. In the present case 75 year old mentally retarded male presented with an ulceration over urethra. Relatives gave history of foreign body insertion. On examination blackish discoloration of distal half of penis was seen. Penectomy was performed as an emergency operation. On histopathology it was reported as penile gangrene.

Experiencia y manejo de dos casos de gangrena de Fournier en pacientes pediátricos en el Instituto Nacional de Salud del Niño - San Borja / Experience and management of two cases of fournier's gangrene in pediatric patients at the Instituto Nacional de Salud del Niño - San Borja, Lima, Peru

RESUMEN La gangrena de Fournier es una patología que se encuentra predominantemente en varones adultos y extremadamente rara en niños. Se han descrito múltiples factores predisponentes en los niños, incluyendo la circuncisión, la dermatitis del pañal, la presencia de abscesos, traumatismos anorrectales y deficiencias inmunológicas. Los signos y síntomas característicos incluyen edema e hiperemia de rápida evolución en la región perineal acompañados de dolor intenso y fiebre. Una vez que se diagnostica la gangrena de Fournier, se debe instaurar tratamiento de forma inmediata, antibióticos endovenosos de amplio espectro y debridamiento quirúrgico temprano del tejido desvitalizado. A continuación presentamos un reporte de casos que incluye las características clínicas y epidemiológicas de dos pacientes pediátricos con gangrena de Fournier que recibieron tratamiento médico y quirúrgico en el Instituto Nacional de Salud del Niño de San Borja.

ABSTRACT Fournier's gangrene is a condition mainly found in adults and it very rarely occurs in children. Multiple predisposing factors have been identified for children, including circumcision, diaper dermatitis, the occurrence of abscesses, anorectal trauma, and immune deficiency. Characteristic signs and symptoms include rapidly progressing edema and hyperemia in the perineal region, accompanied by intense pain and fever. Once Fournier's gangrene is diagnosed, therapy must be immediately instituted, using wide spectrum intravenous antibiotics and early surgical debridement of devitalized tissues. We present a case report including clinical and epidemiological characteristics of two pediatric patients with Fournier's gangrene who received medical and surgical therapy at the Instituto Nacional de Salud del Niño in San Borja, Lima, Peru.
