Progress in diagnosis and treatment of gangrenous cholecystitis / 中华外科杂志

Gangrenous cholecystitis is a kind of acute cholecystitis, whose course of disease progresses rapidly, early diagnosis is difficult and mortality is high, and clinicians are prone to misdiagnosis and missed diagnosis in clinical work.However, gangrenous cholecystitis has been ignored in various guidelines.This paper systematically summarized the pathogenesis, pathological manifestations, epidemiology, clinical diagnosis and treatment of gangrenous cholecystitis, hoping to provide a complete and clear diagnosis and treatment process for clinicians.

Risk factors and interventions: Fournier gangrene in a tertiary hospital: A 10-year experience

@#<p style="text-align: justify;"><strong>Objective.</strong> The study aimed to describe the patient demographic characteristics, clinical factors, surgical interventions, and quality of care parameters in non-survivors and survivors of Fournier's gangrene (FG).</p><p style="text-align: justify;"><strong>Methods.</strong> A total of 131 cases of Fournier's gangrene (FG) were included in a retrospective chart review in the Philippine General Hospital over 10 years using the Department of Surgery research database. We collected data for various direct and derived variables from the identified population. The primary outcome was mortality rate, while other factors studied were genital and colorectal manipulation, bowel diversion, laboratory parameters (white blood cell count, creatinine, hemoglobin).</p><p style="text-align: justify;"><strong>Results.</strong> The mortality rate was 15%. Diabetes mellitus was common comorbidity among patients with Fournier's disease. The following were statistically more common in the non-survivor group: female sex, concomitant bowel diversion surgery. Admission data in the non-survivor group showed a lower serum hemoglobin, a higher serum creatinine, and an increased percentage of patients with an abnormal white blood cell count; these did not statistically differ between cohorts, however. The median time to first antibiotic infusion was six hours. The median time to surgery was 13 hours.</p><p style="text-align: justify;"><strong>Conclusions.</strong> Among patients with Fournier's gangrene, the proportion of women and those undergoing bowel diversion was higher in those who did not survive. The time of infusion of antibiotics or time to surgery did not differ significantly between survivors and non-survivors.</p>

Gangrena isquémica de miembro inferior en paciente con COVID-19 / Ischemic gangrene of low limb in patient with COVID-19

En diciembre de 2019 en la ciudad china de Wuham se reportaron los primeros casos de una nueva enfermedad asociada al SARS-Cov2, denominada COVID-19 y declarada como pandemia por la OMS, con alta letalidad en pacientes mayores de 60 años, que reportaban, en algunos casos, una predisposición a desarrollar microtrombosis y/o trombosis en el sistema arterial y venoso. Cuba presentó su primer caso en abril de 2020, con un comportamiento similar, por lo que nuestro sistema de salud aplicó medidas efectivas, así como puso en práctica el conocimiento acumulado por la comunidad científica. En este sentido, se presenta un caso de gangrena isquémica de miembro inferior en paciente con COVID-19, de interés científico. A la paciente de 42 años se le diagnosticaron COVID-19 y otras comorbilidades, así como un cuadro respiratorio agudo severo, asociado con un proceso de microtrombosis y lesiones de gangrena isquémica distal de los dedos del miembro inferior izquierdo, por la producción de microtrombosis relacionadas con excesiva inflamación, activación plaquetaria, disfunción endotelial y estasis. Según protocolos aplicados en Cuba, la paciente logró sobrevivir a dichas complicaciones. Este caso da a conocer una complicación no relatada en toda su magnitud hasta el momento, lo cual debe ser reportado y conocido como interés científico teórico-práctico de nuestros profesionales de la salud(AU)

In December, 2019 in the Chinese city of Wuhan were reported the first cases of a new disease associated to SARS-CoV-2, called COVID-19 and it was declared as a pandemic by WHO. This disease had high lethality in patients older than 60 years whom in some cases reported predisposition to develop microthrombosis and/or thrombosis in the arterial and venous system. Cuba presented its first case in April, 2020 with a similar behaviour, then our health system implemented effective measures and put into practice all the knowledge accumulated by the scientific community. In this sense, it is presented a scientific interest case of ischemic gangrene of low limb in a patient with COVID-19. The 42 years old female patient was diagnosed with COVID-19 and other comorbidities, as well as with a severe acute respiratory condition, associated to a microthrombosis process and lesions of distal ischemic grangrene of left low limb´s toes, due to the microthrombosis related with excesive inflammation, platelets activation, endothelial dysfunction and stasis. Thanks to the protocols applied in Cuba, the patient survived to those complications. This case shows a complication that is not fully described to the moment, something which must be reported and known as theoric-practical scientific interest of our health professionals(AU)

Major extremity amputations: Indications and post surgery challenges in a Nigeria tertiary institution

Amputation is an ancient procedure which has been practiced for centuries for a variety of indications. The goal of the procedure is to eliminate potential threat to the patient while producing a viable stump for easy rehabilitation.Objective: To identify the indications, postoperative complications and peculiarities of patients with amputation in a native African population.Materials and Methods: This was a prospective study carried out on all consenting patients who had extremity amputation at Federal Medical Centre, Birnin Kebbi, from June 2015 to May 2016. Results: During the study period, there were 47 amputations in 47 patients (34 males and 13 females). The mean age of the patients was 35.73 ± 19.43 years. The most common indication for amputation was traditional bone setter's (TBS) gangrene accounting for 44.7% of cases, followed by diabetic foot syndrome at 25.5%. Camel bites accounted for 6.4% of the amputations. The most common type of amputation was below­knee amputation (46.8%), followed by above­knee amputation (25.5%). Five (10.7%) patients had surgical site infection and only 2.1% of the patients developed phantom limb sensation. None of these patients was fitted with a prosthesis due to the high cost or nonavailability of the prosthesis.Conclusion: Complications of TBS intervention were the leading cause of amputation in this study. Gangrene following camel bites was also found to be a peculiar cause for amputation in this environment. Appropriate public health interventions are necessary to reduce the incidence of preventable gangrene. Provision of prosthesis with adequate technical support is essential to proper rehabilitation of the amputees

Sobre el mal de los ardientes o del fuego de San Antonio / Saint Anthony's fire illness

Resumen El ergotismo es el resultado de la intoxicación con alcaloides derivados del ergot. Durante la edad media y hasta el siglo XIX fue el responsable de grandes epidemias en Europa por el consumo de granos contaminados con el cornezuelo del centeno provocando manifestaciones isquémicas características y afección del sistema nervioso. El ergotismo como se conoció en el Medioevo ha desaparecido, pero aún hoy en día se reportan casos en el marco de uso terapéutico de ergotamínicos. Se pretenden describir algunos de sus aspectos históricos y clínicos distintivos.

Abstract Ergotism is the result of intoxication with alkaloids derived from ergot. During the middle ages and until the nineteenth century it was responsible for major epidemics in Europe for the consumption of grains contaminated with ergot, causing characteristic ischemic manifestations and nervous system involvement. Ergotism as it was known in the Middle Ages has disappeared, but even today cases are reported in the therapeutic use of ergotamine. Some of its distinctive historical and clinical aspects are intended to be described.

Prognostic Factors in Patients Treated with Drug-Coated Balloon Angioplasty for Symptomatic Peripheral Artery Disease

PURPOSE: Aim of this study is to report real-life experience on the treatment of peripheral artery disease (PAD) with a specific drug-coated balloon (DCB), and to evaluate potential prognostic factors for outcomes. MATERIALS AND METHODS: This is a retrospective study reporting outcomes in patients with PAD who were treated with the Lutonix DCB during a four-year period. Major outcomes included: all-cause mortality, amputation, clinical improvement, wound healing and target lesion revascularization (TLR). Mean follow-up was 24.2±2.3 months. RESULTS: Overall, 149 patients (mean age: 68.6±8.3 years; 113 males) were treated, either for intermittent claudication (IC) (n=86) or critical limb ischemia (CLI) (n=63). More than half the target lesions (n=206 in total) were located in the superficial femoral artery and 18.0% were below-the-knee lesions. CLI patients presented more frequently with infrapopliteal (P=0.002) or multilevel disease (P=0.0004). Overall, all-cause mortality during follow-up was 10.7%, amputation-free survival was 81.2% and TLR-free survival was 96.6%. CLI patients showed higher all-cause mortality (P=0.007) and total amputation (P=0.0001) rates as well as lower clinical improvement (P=0.0002), compared to IC patients. Coronary artery disease (CAD), gangrene and infrapopliteal disease were found to be predictors for death whereas CLI and gangrene were found to be predictors for amputation, during follow-up. CONCLUSION: PAD treatment with Lutonix DCBs seems to be an efficient and safe endovascular strategy yielding promising results. However, CAD, gangrene, CLI and infrapopliteal lesions were found to be independent predictors for adverse outcomes. Larger series are needed to identify additional prognostic factors.

Staged lower lip reconstruction following gangrenous stomatitis in an immunosuppressed patient

A 70-year-old male with a history of diabetes mellitus, hypertension, and coronary stent insertion visited our hospital 7 days after biting his lower lip. Swelling and inflammation had worsened despite debridement and antibiotic treatment. On the 8th hospital day, fungal infection with Candida albicans and superimposed bacterial infection with Klebsiella pneumoniae were found on tissue culture. Extensive necrosis resulted in a defect of approximately 3/4 of the entire lower lip and a full-layer skin defect from the vermilion to the gingivobuccal sulcus at the right corner of the mouth. To correct drooling, incomplete lip sealing, and trismus, staged reconstruction was performed with consideration of cosmetic and functional features. The treatment process using staged reconstruction and antifungal treatment for an extensive lower lip defect caused by fungal stomatitis is described.

Usefulness of Percutaneous Transluminal Angioplasty before Operative Treatment in Diabetic Foot Gangrene / 대한족부족관절학회지

PURPOSE: Diabetic foot gangrene has a high morbidity rate and a great influence on the quality of life. Amputation is an appropriate treatment if conservative treatment is impossible according to the severity of gangrene and infection. The purpose of this study was to evaluate the usefulness of preoperative percutaneous transluminal angioplasty for the postoperative outcome. MATERIALS AND METHODS: From February 2013 to April 2016, among 55 patients with diabetic foot gangrene, who require surgical treatment, percutaneous transluminal angioplasty was performed on patients with an ankle brachial index (0.9 and stenosis) 50% on angiographic computed tomography. The study subjects were 49 patients, comprised of 37 males (75.5%) and 12 females (24.5%). The mean age of the patients was 70.0±9.6 years. The treatment results were followed up according to the position and length of the lesion and the changes during the follow-up period. RESULTS: As a result of angiography, there were 13 cases of atherosclerotic lesions in the proximal part, 11 cases in the distal part and 25 cases in both the proximal and distal parts. As a result of the follow-up after angiography, in 13 patients, the operation was not performed and only follow-up and dressing were performed around the wound. Sixteen patients underwent debridement for severe gangrene lesions and 20 patients, in whom the gangrene could not be treated, underwent amputation (ray amputation or metatarsal amputation, below knee amputation). CONCLUSION: Preoperative percutaneous angioplasty in diabetic foot gangrene patients with peripheral vascular occlusive disease is simple, and 59.2% of the patients with diabetic foot gangrene could be treated by conservative treatment or debridement.

Ecthyma gangrenosum: a report of eight cases

Abstract: Ecthyma gangrenosum is a rare skin infection classically associated with Pseudomonas aeruginosa. We performed a retrospective study of all cases diagnosed with ecthyma gangrenosum from 2004-2010 in a university hospital in Mexico (8 cases, 5 female patients and 3 male patients, ages between 4 months and 2 years). The most common risk factor for ecthyma gangrenosum is neutropenia in immunocompromised patients. In previously healthy patients, immunological evaluation is important to rule out underlying immunodeficiency. Ecthyma gangrenosum in healthy patients has a high mortality rate and early diagnosis and aggressive antibiotic treatment is imperative as it can improve patients' prognosis.

Factores predictivos de colecistitis aguda gangrenosa / Predictive factors of acute gangrenous cholecystitis

Introducción: La colecistitis aguda gangrenosa (CAG) es una complicación severa de la colecistitis aguda, afectando entre el 2 y 20% de las mismas. En la actualidad no hay disponibles guías definidas para detectar estos casos y definir su conducta quirúrgica con rapidez. El objetivo de este trabajo es contribuir al estudio de los factores predictivos de la CAG para identificar los pacientes que requieren cirugía de urgencia. Material y métodos: Se realizó una búsqueda retrospectiva de pacientes que fueron sometidos a colecistectomía con diagnóstico preoperatorio de colecistitis aguda en el Nuevo Hospital San Roque, entre enero de 2011 y diciembre de 2012. El Nuevo Hospital San Roque es un centro público de atención de tercer nivel al que acceden de forma gratuita los habitantes de la Ciudad de Córdoba (Argentina) y alrededores que no cuentan con cobertura de salud privada. Los factores de riesgo preoperatorios evaluados incluyeron sexo, edad, diabetes, obesidad, vómitos, fiebre, recuento de glóbulos blancos, eritrosedimentación, enzimas hepáticas, amilasa y hallazgos ecográficos como diámetro de la pared vesicular y líquido perivesicular. Los pacientes fueron divididos en 2 grupos de acuerdo con el diagnóstico anatomopatológico: el grupo 1 incluyó pacientes con CAG y el grupo 2, pacientes con colecistitis aguda no gangrenosa. Resultados: De un total de 183 pacientes sometidos a colecistectomía, 101 (55,1%) presentaron CAG. El análisis multivariado determinó que en nuestro grupo de estudio la razón de probabilidades de CAG asociadas a las variables fiebre, diabetes, y sexo masculino son mayores de 2 y estadísticamente significativas. Asimismo, la razón de probabilidades de CAG aumenta con el nivel de glóbulos blancos y eritrosedimentación. Conclusión: Las variables fiebre, diabetes, sexo masculino, glóbulos blancos, y eritrosedimentación pueden ser consideradas factores predictivos independientes en nuestro caso de estudio.

Introduction: Acute gangrenous cholecystitis (AGC) is a severe complication of acute cholecystitis affecting between 2 and 20% of them. To date, there are no defined guidelines available to triage high-risk surgical patients. Our objective is to contribute to the literature studying predictive factors of AGC aimed at identifying patients who require emergency surgery. Materials and methods: We conducted a retrospective search of patients who underwent cholecystectomies with preoperative diagnosis of acute cholecystitis at Nuevo Hospital San Roque between January 2011 and December 2012. Nuevo Hospital San Roque is a public hospital in Argentina that provides health services to non-privately insured residents of the Cordoba metropolitan area. The resulting sample was used to perform a multivariate analysis encompassing the following preoperative risk factors: gender, age, diabetes, obesity, vomiting, fever, white blood cell count, erythrocyte sedimentation rate, liver enzymes, amylase and sonographic findings like diameter of gallbladder wall and perivesicular liquid. Patients were divided into two groups according to pathological diagnosis: group 1 included patients with acute AGC and group 2 with no gangrenous acute cholecystitis. Results: One hundred and one patients presented AGC out of a total of 183 patients analyzed. Our multivariate analysis determined that the odds ratio of CAG associated with the variables fever, diabetes, and male gender are greater than 2 and statistically significant. Likewise, the odds ratio of CAG is increasing in the level of white blood cells and in the erythrocyte sedimentation rate. Conclusion: We found that fever, diabetes, male gender, white blood cells, and erythrocyte sedimentation rate can be considered independent predictors in our sample.

An unexpected gangrenous duplication of ileum

Alimentary tract duplication is a rare congenital anomaly which may involve any part of the alimentary tract extending from stomach to rectum. Clinical presentation may mimic an inflamed appendix as described in this case. A 9-year-old boy with a clinical diagnosis of perforated appendix was noted to have a normal appendix intra-operatively. On further search for an underlying pathology, a gangrenous ileal duplication was discovered. En-bloc resection with primary bowel anastomosis was done. Histopathology report revealed a gangrenous small bowel duplication. We discuss the preoperative diagnostic dilemma and management options in approaching this rare entity.

Vacuum sealing drainage as an adjuvant treatment of penile and scrotal gangrene: Clinical analysis of 4 cases / 中华男科学杂志

Objective@#To search for an optimal strategy for the treatment of penile and scrotal gangrene by analyzing the clinical effect of vacuum sealing drainage (VSD) as an adjuvant treatment on this disease.@*METHODS@#We retrospectively analyzed the clinical data about 4 cases of penile and scrotal gangrene treated by VSD as an adjuvant treatment from January 2015 to June 2016. The 4 patients all underwent early extensive and radical debridement of gangrene of the scrotum and penis and received intravenous injection of two broad-spectrum antibiotics, followed by VSD for wound drainage and irrigation.@*RESULTS@#Adequate wound drainage was achieved in all the 4 cases, the gangrene range rapidly localized and testicular necrosis avoided. The wound surface healed satisfactorily after cleansing and suturing. The patients were followed up for 3 months after discharged from the hospital and none experienced recurrence.@*CONCLUSIONS@#VSD combined with early adequate debridement can effectively localize the gangrene range, significantly reduce the frequency of changing dressings and shorten the hospitalization time of the patient, and therefore is a very effective adjuvant treatment of penile and scrotal gangrene.

Symmetrical peripheral gangrene complicating ventricular pseudoaneurysm: a report of an unusual case and a brief review of the literature

Abstract Symmetrical peripheral gangrene is an ischemic necrosis simultaneously involving the distal portions of two or more extremities without any proximal arterial obstruction or vasculitis. It may occur as a result of a large number of infectious and non-infectious causes. A few cases of symmetrical peripheral gangrene associated with cardiac disease have been described in the literature. We describe a case of symmetrical peripheral gangrene complicating ventricular pseudoaneurysm, probably a hitherto unreported occurrence. In this report, we sought to emphasize the importance of cardiac evaluation while dealing with a case of symmetrical peripheral gangrene.

Ectima gangrenoso secundario a Staphylococcus aureus / Ecthyma gangrenosum caused by Staphylococcus aureus

El ectima gangrenoso es una vasculitis necrosante poco frecuente, en la mayoría de los casos secundaria a sepsis por Pseudomonas aeruginosa en pacientes inmunocomprometidos. Sin embargo, existen reportes de ectima gangrenoso secundarios a otras etiologías infecciosas. Presentamos un caso de ectima gangrenoso asociado a una infección por Staphylococcus aureus resistente a meticilina en una paciente sin los factores de riesgo clásicos de inmunosupresión que se describen en la literatura médica.

Ecthyma gangrenosum is an uncommon necrotizing vasculitis, in most cases secondary to sepsis by Pseudo-mona aeruginosa in immunocompromised patients. However, there have been several reports of ecthyma gangre-nosum caused by other infectious etiologies. We report an unusual case of ecthyma gangrenosum associated with methicillin-resistant Staphylococcus aureus infection in a patient without the classic immunological risk factors described in the literature.

Otitis externa maligna con ectima gangrenoso en un paciente con infección por VIH / Malignant otitis externa with ecthyma gangrenosum in an hiv-positive patient

La otitis externa maligna es considerada una infección invasiva del conducto auditivo externo, infrecuente y sumamente agresiva, que llega, en ocasiones, a comprometer la base del cráneo. Se presenta habitualmente en inmunocomprometidos, incluidos aquellos con infección por VIH. El ectima gangrenoso es una infección cutánea localizada, inusual, causada, en la mayoría de los casos por Pseudomonas aeruginosa, con compromiso multisistémico y evolución tórpida. La asociación entre ambas entidades es aún más rara. A continuación, presentamos el caso de una mujer de 37 años, con el antecedente principal de infección por VIH desde hace 10 años, adherente al tratamiento antirretroviral y, a pesar de mantener una adecuada respuesta inmunológica y virológica, se presenta a la urgencia de nuestro hospital en shock séptico por otitis externa maligna, con ectima gangrenoso y posible síndrome hemofagocítico como complicación, aislándose Pseudomonas aeruginosa como agente causal.

Malignant otitis externa is an aggressive, infrequent and invasive infection of the external auditory canal. In some cases it leads to skull base compromise, particularly in immunocompromised individuals, including HIV-positive patients. Ecthyma gangrenosum is an unusual, localized cutaneous infection, caused mostly by Pseudomonas aeruginosa, with systemic compromise and a torpid evolution. An association between these 2 entities is even more rare. We present the case of a 37-year old woman with a history of 10 years’ HIV infection and good adherence to antiretroviral therapy. Although she had an adequate immunological and virological response, she presented at our emergency department in septic shock due to malignant otitis externa with ecthyma gangrenosum and possible haemophagocytic syndrome as a complication, with Pseudomonas aeruginosa determined to be the causative agent.

Gas Gangrene Caused by Streptococcus anginosus / 대한내과학회지

Gas gangrene, a subset of necrotizing myositis, is a bacterial infection that produces gas in tissues in gangrene. It is usually caused by Clostridium species, most commonly Clostridium perfringens. Streptococcus anginosus is a rare cause of gas gangrene, with very few cases reported. We report a rare case of traumatic gas gangrene caused by S. anginosus in a 57-year-old female with diabetes after being stabbed with scissors.

Pulmonary Embolism Associated with Scrub Typhus / 대한내과학회지

Acute pulmonary embolism is a cardiovascular emergency and is a major cause of morbidity and mortality. Endothelial damage secondary to invasion by Orientia tsutsugamushi can lead to focal occlusive endangiitis, causing microinfarcts in various tissues. This localized process can also cause venous thrombosis and peripheral gangrene. However, pulmonary embolism associated with scrub typhus has not been reported in Korea. Here, we report a patient diagnosed with pulmonary embolism associated with scrub typhus, the first report of its kind. The patient had an eschar with detection of anti-tsutsugamushi antibody, fever, dyspnea, and a maculopapular rash over the entire body. He was treated with doxycycline and anticoagulation therapy.
