Manejo de hemangioma ulcerado segmentario: combinación de tratamiento sistémico y tópico en dos casos pediátricos / Management of ulcers on a segmental hemangioma: A combination of systemic and topical therapies in two pediatric cases

Los hemangiomas infantiles (HI) son los tumores benignos más frecuentes de la infancia; la variante segmentaria es rara y se asocia con un mal pronóstico. Una de sus principales complicaciones es la ulceración durante la fase de crecimiento del tumor, a pesar de no presentar características macroscópicas compatibles con una lesión agresiva. El manejo en estos casos es dificultoso e impone la necesidad de asociar múltiples estrategias, algunas orientadas específicamente a impedir la proliferación del hemangioma y otras orientadas a la curación de la herida, el manejo del dolor y la prevención de la infección agregada. Presentamos dos casos a fin de comunicar nuestra experiencia respecto del manejo de dicha patología y su evolución final.

Infantile hemangiomas (IHs) are the most common benign tumors of childhood, and segmental ones are rare and associated with a poor prognosis. While these tumors look harmless, one of their main related complications is ulceration during tumor growth. The management in these cases is extremely challenging, requiring a combination of multiple approaches, some specifically aimed at preventing the proliferation of the hemangioma and others aimed at wound care, pain management, and prevention of further infection. Here we discuss two cases to narrate our experience on the management of this condition and its outcome.

L-arginine-induced esophagitis, report of six cases / Reporte de seis casos de esofagitis inducida por L-arginina

Abstract Background: Drug-induced esophagitis is an uncommon diagnosis in the pediatric population. The following is a report of six adolescents with L-arginine-induced esophagitis. Case reports: All patients were under treatment with L-arginine for short stature. After using the prescribed medication for 1-3 months, all cases started with severe retrosternal pain, odynophagia, and dysphagia. The upper gastrointestinal endoscopies showed ulcers located in the mid esophageal mucosa. Conclusions: In the presence of acute severe odynophagia, dysphagia, and retrosternal pain, drug-induced esophagitis should be considered as a possible diagnosis. Treatment includes liquid diet, pain control, sucralfate, omeprazole, and interruption of L-arginine. In addition, the physician should explain preventive measures focused on patient and family education on the drug side effects and precise instructions on how to take medications, as well as a careful balance of risk and benefits of any medication. At present, there are no clinical trials that support the use of L-arginine in treatment of short stature.

Resumen Introducción: La esofagitis inducida por medicamentos es un diagnóstico poco frecuente en pacientes pediátricos. A continuación, se describe una serie de seis casos de pacientes menores de 15 años con esofagitis inducida por L-arginina. Casos clínicos: Los seis casos se encontraban en tratamiento con L-arginina por talla baja e iniciaron con dolor retroesternal, odinofagia y disfagia de rápida instalación. Cuatro de ellos acudieron al servicio de urgencias por la intensidad de los síntomas. Los hallazgos en la endoscopia del tubo digestivo alto fueron úlceras en la mucosa del esófago a la altura del tercio medio, zona de estrechez natural por la compresión del bronquio izquierdo. Conclusiones: En presencia de odinofagia, disfagia, dolor retroesternal y el antecedente de la ingesta de L-arginina, la esofagitis inducida por fármacos debe considerarse como una posibilidad diagnóstica. El tratamiento está basado en el manejo del dolor, sucralfato, omeprazol, así como la suspensión del medicamento y medidas preventivas centradas en la educación del paciente y los familiares sobre los riesgos y beneficios de un medicamento y la forma correcta de administrarlo.

Úlcera vulvar aguda de Lipschütz / Acute vulvar ulcer of Lipschütz

RESUMEN La úlcera de Lipschütz es una entidad poco frecuente e infradiagnosticada. Se presenta el caso de una paciente de 24 años sin antecedente de contacto sexual que consultó por aparición súbita de úlceras vulvares dolorosas, en el contexto de un cuadro pseudogripal. Se discuten los principales diagnósticos diferenciales, dado que es una enfermedad no relacionada con enfermedades de transmisión sexual y poco reconocida por los profesionales de la salud, que precisa de manejo conservador.

ABSTRACT Lipschütz ulcer is a rare underdiagnosed entity. We present the case of a 24-year-old patient without history of sexual contact who consulted for sudden occurrence of painful vulvar ulcers, in the context of flu-like symptoms. The main differential diagnoses are discussed, as it is a disease unrelated to sexually transmitted diseases and little recognized by health professionals, which requires conservative management.

Flebectasia yeyunal como causa de hemorragia digestiva media masiva / Jejunal phlebectasia as a cause of massive gastrointestinal hemorrhage

Las anormalidades vasculares del tracto gastrointestinal son una causa común de sangrado digestivo. La mayoría se localizan al alcance de la endoscopía digestiva alta y/o colonoscopía, una vez descartado ello, obliga a considerar al intestino delgado como causa de la hemorragia. El manejo exitoso de una hemorragia digestiva depende principalmente de la localización oportuna de la fuente del sangrado, sin embargo esta tarea puede ser difícil, cuando la causa no está al alcance de los métodos convencionales. Presentamos el caso de un paciente varón de 21 años cuyo diagnóstico fue una flebectasia yeyunal sangrante, luego de una cuidadosa evaluación de los hallazgos de la cápsula endoscópica y laparoscopía.

Vascular abnormalities of the gastrointestinal tract are a common cause of gastrointestinal bleeding. Most of them are located within the reach of the upper endoscopy or colonoscopy, although once discarded, it forces to consider small bowel as the source of bleeding. The successful management of a gastrointestinal bleeding depends mainly on the timely location of the source of bleeding. Nevertheless this task can be difficult when the cause is not within the reach of conventional methods. We present a case of a 21 year-old men in which the diagnosis of bleeding yeyunal phlebectasia was made by the findings of the capsule endoscopy and laparoscopy.

Estenosis de las arterias cubital y radial en pacientes con esclerosis sistémica, comparado con un grupo control / Ulnar and radial stenosis in systemic sclerosis

Objetivos: describir la frecuencia de estenosis arterial (cubital y radial) en pa-cientes con esclerosis sistémica (ES); analizar la relación entre estenosis macro-vascular y úlceras digitales. Método: se incluyeron 57 pacientes con ES, según la clasificación del Colegio Americano de Reumatología de 1980 y 21 pacientes sin ES. Se realizó ecografía doppler arterial de miembros superiores. Resultados: la estenosis en al menos una arteria cubital se objetivó en 31% de pacientes con ES (18/57) (p=0.003). Se objetivó estenosis radial en 9 de 57 pacientes con ES (15%) y en uno de los 21 controles (p=0.19). En el modelo multivariado, los predicto-res de úlceras digitales fueron inicio de Raynaud antes de los 40 años (OR 5.3 IC95% 1.54-18.22, p=0.008) y patrón tardío en la capilaroscopia (OR 4.4 IC95% 1.29-15.63, p=0.018). Conclusiones: un tercio de los pacientes ES presentó este-nosis cubital. El compromiso de los grandes vasos no se asoció a úlceras digitales.

Objectives: to describe the frequency of ulnar and radial stenosis in SSc patients. Analyze the correlation between arterial stenosis and digital ulcers. Methods: we included 57 SSc consecutive patients who fulfilled ACR 1980 classification criteria, and 21 healthy controls. An arterial ecodoppler was performed to all participants. Results: the presence of stenosis in at least one ulnar artery was observed in 18 of 57 patients with SSc (31%) and in none of the 21 controls (p=0.003). Stenosis was present in at least one radial artery in 9 of 57 SSc patients (15%) (p=0.19). In multivariate model, the best predictors of digital ulcers were age at onset of Ray-naud phenomenon before 40 years (OR 5.3 95%CI 1.54-18.22, p=0.008) and late SD pattern (OR 4.4 95%CI 1.29-15.63, p=0.018). Conclusion: in the present series, ulnar stenosis was observed frequently in SSc patients. Stenosis of large vessels was not associated with digital ulcers.

Risk of digital ulcers occurrence in systemic sclerosis: a cross-sectional study

Abstract Background/objective: Digital ulcers (DUs) represent a frequent complication of systemic sclerosis (SSc). The aim of this study was to evaluate clinical, serological and capillaroscopy features that are associated with DUs in patients with SSc. Methods: In this bicentric cross-sectional study, 70 patients with SSc were consecutively selected from March 2016 to April 2017. Demographic and clinical features, including the presence of active DUs, were collected. Videocapillaroscopy was performed in all patients. Results: Among the 70 patients included (mean age of 46.8 years, mean disease duration of 9.41 years), 14 (20%) had active DUs. Based on multivariate analysis, the presence of anti-Scl-70 antibodies, the HAQ-DI score, and the capillary loss score were independently associated with DUs with odds ratios of 7.96 (95% CI 1.32-47.99), 55.77 (95% CI 1.76-1764.28), and 16.66 (95% CI 2.07-133.81), respectively. Conclusions: The presence of avascular areas in capillaroscopy, elevation of HAQ-DI score and anti-Scl-70 antibodies were independent factors associated with DUs in patients with SSc.

Late surgical complications after gastric by-pass: a literature review / Complicações cirúrgicas tardias após bypass gástrico: revisão da literatura

INTRODUCTION: Gastric bypass is today the most frequently performed bariatric procedure, but, despite of it, several complications can occur with varied morbimortality. Probably all bariatric surgeons know these complications, but, as bariatric surgery continues to spread, general surgeon must be familiarized to it and its management. Gastric bypass complications can be divided into two groups: early and late complications, taking into account the two weeks period after the surgery. This paper will focus the late ones. METHOD: Literature review was carried out using Medline/PubMed, Cochrane Library, SciELO, and additional information on institutional sites of interest crossing the headings: gastric bypass AND complications; follow-up studies AND complications; postoperative complications AND anastomosis, Roux-en-Y; obesity AND postoperative complications. Search language was English. RESULTS: There were selected 35 studies that matched the headings. Late complications were considered as: anastomotic strictures, marginal ulceration and gastrogastric fistula. CONCLUSION: Knowledge on strategies on how to reduce the risk and incidence of complications must be acquired, and every surgeon must be familiar with these complications in order to achieve an earlier recognition and perform the best intervention. .

INTRODUÇÃO: O bypass gástrico é hoje o procedimento bariátrico mais realizado, mas, apesar disso, várias complicações podem ocorrer com variada morbimortalidade. Provavelmente todos os cirurgiões bariátricos conhecem essas complicações, mas como a cirurgia bariátrica continua a se espalhar, o cirurgião geral deve estar familiarizado com essas complicações e seu manuseio. As complicações do bypass gástrico podem ser divididas em dois grupos: as precoces e tardias, tendo em conta o período de duas semanas após a operação. Este artigo irá focar as tardias. MÉTODO: Foi realizada revisão da literatura utilizando as bases Medline/PubMed, Cochrane Library, SciELO, e informações adicionais sobre sites institucionais de interesse cruzando os descritores: bypass gástrico AND complicações; seguimento AND complicações; complicações pós-operatórias AND anastomose, Roux-en-Y; obesidade AND complicações pós-operatórias. A língua usada para a busca foi o inglês. RESULTADOS: Foram selecionados 35 estudos que combinavam com os descritores. As complicações tardias foram consideradas como: estenose de anastomose, ulceração marginal e fístula gastrogástrica. CONCLUSÃO: O conhecimento sobre as estratégias de como reduzir o risco e incidência das complicações deve ser adquirido ao longo do tempo, e cada cirurgião deve estar familiarizado com essas complicações, a fim de reconhecê-las precocemente e realizar a melhor intervenção. .

Cell Therapy for Wound Healing

In covering wounds, efforts should include utilization of the safest and least invasive methods with goals of achieving optimal functional and cosmetic outcome. The recent development of advanced wound healing technology has triggered the use of cells to improve wound healing conditions. The purpose of this review is to provide information on clinically available cell-based treatment options for healing of acute and chronic wounds. Compared with a variety of conventional methods, such as skin grafts and local flaps, the cell therapy technique is simple, less time-consuming, and reduces the surgical burden for patients in the repair of acute wounds. Cell therapy has also been developed for chronic wound healing. By transplanting cells with an excellent wound healing capacity profile to chronic wounds, in which wound healing cannot be achieved successfully, attempts are made to convert the wound bed into the environment where maximum wound healing can be achieved. Fibroblasts, keratinocytes, adipose-derived stromal vascular fraction cells, bone marrow stem cells, and platelets have been used for wound healing in clinical practice. Some formulations are commercially available. To establish the cell therapy as a standard treatment, however, further research is needed.

An unusual case of invasive aspergillus ulcerative tracheobronchitis without involvement of lung parenchyma in a post-renal transplant patient.

We present the case of a 54-year-old male, who presented with respiratory complaints four months after he underwent renal transplantation. Bronchoscopy showed ulcerated mucosa of the left main bronchus and computed tomography (CT) of the thorax showed foci of air within the bronchial wall. A biopsy from the lesion showed septate fungal hyphae, dichotomously branching at acute angles. A locally invasive Aspergillus ulcerative tracheobronchitis with no parenchymal involvement is an important cause of tracheobronchitis in post-renal transplant patients. An early diagnosis and institution of appropriate treatment can improve the outcome. A combination treatment of caspofungin and voriconazole can be considered if patient is not responding to voriconazole alone.

Pneumomediastino espontâneo associado a lesões laríngeas e úlceras traqueais na dermatomiosite / Spontaneous pneumomediastinum associated with laryngeal lesions and tracheal ulcer in dermatomyositis

O presente estudo descreve uma paciente de 41 anos de idade com dermatomiosite, doença pulmonar intersticial e vasculopatia cutânea que desenvolveu pneumomediastino. Durante exame de broncoscopia foram encontradas lesões pálidas na laringe, que se estendiam para a árvore traqueobrônquica, e úlceras profundas na parede membranácea da traqueia. O exame histopatológico revelou presença de processo inflamatório secundário à vasculite, mas sem sinais de infecção. Lesões nas vias aéreas superiores e inferiores em paciente com dermatomiosite são raríssimas. A associação de dermatomiosite com úlceras profundas de mucosa e pneumomediastino não está bem esclarecida, mas a broncoscopia é um exame que deve ser utilizado para aperfeiçoar a avaliação.

We described a 41-year-old woman with dermatomyositis, interstitial lung disease, and cutaneous vasculopathy who developed a pneumomediastinum. The routine bronchoscopy investigation found pale lesions in the larynx, that extended to the tracheobronchial tree, and deep ulcers in the membranous wall of the trachea. The histopathology examination revealed an inflammatory process that was diagnosed secondary to the vasculitis, but no infections. Superior and inferior airway lesions in the same patient with dermatomyositis is a very rare condition. The association of dermatomyositis with deep mucosal ulcers and pneumomediastinum is not clear, but a bronchoscopic examination should be used to improve evaluation.

Tratamento cirúrgico da úlcera loxoscélica: solução prática para um problema de difícil resolução / Surgical treatment of ulcer loxoscélica: practical solution to a difficult problem to solve

Contexto: O manuscrito descreve a reparação cirúrgica de uma úlcera crônica resultante da picada de uma aranhamarrom,um problema de difícil resolução, o qual habitualmente demora meses até a cicatrização.Descrição do caso: A vítima foi picada na coxa direita e desenvolveu fases de envenenamento típicas da picada deLoxosceles, incluindo a placa mármore, a escara e a úlcera profunda e de bordos emoldurados, características doacidente. Devido ao processo cicatricial lento, cuidados intensivos com curativos, dificuldade na deambulação, além dofator estético, optou-se por cirurgia excisional da lesão e sutura direta das bordas. O tratamento cirúrgico proporcionoucicatrização total da lesão dentro de 15 dias.Conclusões: A úlcera loxoscélica apresenta difícil cicatrização, evoluindo para a cronicidade. A cirurgia com excisãocompleta e síntese primária constitui técnica adequada para a cura da doença.

Ulceración rectal como una complicación del uso de sistema de control fecal Fexi-Seal: relato de casos / Ulceração retal como uma complicação do uso do sistema de controle fecal Fexi-Seal: relato de casos / Rectal ulceration due to using the Fexi-Seal fecal management system: a case report

El Sistema Fexi-Seal es un dispositivo desarrollado para proporcionar mejores cuidados a los pacientes críticos con incontinencia fecal. Existen trabajos que demuestran la seguridad y eficacia del dispositivo, siendo escasos los relatos relacionados con eventos adversos. El presente artículo presenta dos casos de pacientes críticos portadores de Fexi-Seal que desarrollaron complicaciones con su uso. El sistema se mostró eficaz para el tratamiento, sin embargo, es necesaria atención especial en su manejo, particularmente en cuanto al alivio periódico de la presión de la ampolla rectal y al posicionamiento correcto de la bolsa colectora en la cama para evitar tracción excesiva. El Sistema Flexi-Seal permite manejar adecuadamente la diarrea en pacientes críticos, mejorando su bienestar y disminuyendo las complicaciones asociadas a ella, aunque se torna necesario aumentar el conocimiento sobre las complicaciones relacionadas con su empleo.

O Sistema Fexi-Seal é um dispositivo desenvolvido com o objetivo de proporcionar melhores cuidados aos pacientes críticos com incontinência fecal. Existem trabalhos que demonstram a segurança e a eficácia do dispositivo, sendo, porém, escassos os relatos relacionados aos eventos adversos. O presente artigo apresenta dois casos de pacientes críticos portadores de Fexi-Seal que desenvolveram complicações com seu uso. O Sistema mostrou-se eficaz para o tratamento, no entanto, é necessária atenção especial no seu manejo, particularmente quanto ao alívio periódico da pressão na ampola retal e o posicionamento correto da bolsa coletora na cama para evitar tração excessiva. O Sistema Fexi-Seal permite manejar adequadamente a diarreia em pacientes críticos, melhorando o bem-estar e diminuindo as complicações associadas a ela, porém faz-se necessário aumentar o conhecimento sobre as complicações relacionadas ao seu emprego.

The Flexi-Seal Fecal Management System is a device designed to offer improved care to critical care patients with fecal incontinence. Studies have proven the safety and effectiveness of the device, but there are scarce reports on the adverse events. This article presents two cases of critical care patients who developed complications associated with the use of the Flexi-Seal FMS. The System proved to be effective for the treatment; however, it requires special care in the handling, particularly regarding the periodical relief of pressure from the retention balloon and the correct positioning of the collection bag on the bed, so as to avoid excessive traction. The Flexi-Seal is useful to manage diarrhoea in critical patients, improving their well-being and reducing associated complications. Nevertheless, there is a need to improve knowledge related to the complications that may occur.

Cutaneous CD30 positive anaplastic large cell lymphoma

An adult Caucasian male presented with a solitary abscess-like lesion on his left thigh. The lesion later on ulcerated and developed a central eschar. The initial differential diagnoses included deep mycosis, insect bite reaction or atypical mycobacterial infection. Histology confirmed it to be a CD30 positive anaplastic large cell lymphoma. Haematologyoncology screen was carried out and the patient started on local field radiotherapy. Localized lymphomatous lesions can be treated with surgical excision or local radiotherapy. Systemic treatments are reserved for generalized disease. The prognosis depends on the extent of involvement

Scleral ulceration after vitreoretinal surgery.

Scleral ulceration after ocular surgery is a rare but serious complication. Determination of the underlying systemic and local causes is critical for treatment. An unusual case of ischemic scleral ulceration after vitreoretinal surgery in a diabetic patient is reported. Patient was successfully treated with a pedicle conjunctival graft.

Quality of reporting and of methodology of studies on interventions for trophic ulcers in leprosy: a systematic review.

BACKGROUND: In the process of conducting a systematic review on interventions for skin lesions due to neuritis in leprosy, we assessed several primary papers with respect to the quality of reporting and methods used in the studies. Awareness of what constitutes weak points in previously conducted studies may be used to improve the planning, conducting and reporting of future clinical trials. AIMS: To assess the quality of reporting and of methodology in studies of interventions for skin lesions due to neuritis in leprosy. METHODS: Items of importance for preventing selection bias, detection bias, attrition bias and performance bias were among items assessed. The items for assessing methodological quality were used as a basis for making the checklist to assess the quality of reporting. RESULTS: Out of the 854 references that we inspected eight studies were included on the basis of the inclusion criteria. The interventions tested were dressings, topical agents and footwear and in all studies healing of ulcers was the main outcome measure. Reporting of both, methods and results suffered from underreporting and disorganization. The most under-reported items were concealment of allocation, blinding of patients and outcome assessors, intention to treat and validation of outcomes. CONCLUSION: There is an apparent need to improve the methodological quality as well as the quality of reporting of trials in leprosy ulcer treatment. The most important threat in existing studies is the threat of selection bias. For the reporting of future studies, journals could promote and encourage the use of the CONSORT statement checklist by expecting and requiring that authors adhere to it in their reporting.

Úlcera de lengua como presentación del Histoplasma capsulatum / Tongue ulceration as a presentation of Histoplasma capsulatum infection

La histoplasmosis diseminada progresiva es una enfermedad que se manifiesta como reactivación de una infección latente en pacientes inmunodeprimidos, especialmente en personas con déficit en la inmunidad celular. Existen formas agudas, subagudas y crónicas. Las lesiones focales, en especial úlceras mucocutáneas, predominan en la forma diseminada crónica. Reportamos el caso de una paciente con artritis reumatoidea, que controlaba su patología con fármacos antirreumáticos modificadores de la enfermedad (DMARD), la que consultó por úlcera de lengua como única manifestación de una histoplasmosis diseminada crónica. La histopatología fue compatible y el cultivo positivo para Histoplasma capsulatum. La serología para el HIV fue negativa. Existen pocos casos publicados de pacientes con esta localización atípica en forma aislada, en particular aquellos HIV negativos. El itraconazol y la anfotericina B son las dos drogas más utilizadas para tratar esta enfermedad. Los datos clínicos sobre los nuevos azoles, voriconazol y posaconazol son limitados.

The progressive disseminated histoplasmosis is a disease produced by reactivation of latent infection in immunocompromised host, specially in persons with defective cell-mediated immunity. There are acute, subacute and chronic forms in the progressive illness. Focal lesions, specially mucocutaneous ulcers, are most frequent in the chronic disseminated forms. We reported a patient with rheumatoid arthritis treated with disease modifying antirheumatic drug (DMARD), with an ulcer of the tongue as only clinical manifestation of a chronic disseminated histoplasmosis. The histopathology was compatible, and the culture was positive for Histoplasma capsulatum. The serology for the HIV was negative. There are few published cases of this isolated form, particularly in patients with HIV negative serological test. Itraconazole and amphotericin B are the most frequently drugs used for the treatment in this disease. Clinical data on the new azoles, voriconazole and posaconazole, are limited.

Local variations in the frequency and pattern of dermatoses in amputees in earthquake affected areas

To study the regional variations in the frequency and pattern of dermatoses in amputees in earthquake affected areas. District headquarter hospitals, Mansehra and Abbottabad. All patients with amputations and associated skin disease belonging to any age groups and gender were enrolled for the study. Three visits were made to the research areas. The first visit was for publicizing the time and venue of camps. In the second visit all patients presenting with any major or minor amputation acquired after the earthquake were enrolled in the study. A detailed history was taken and physical examination carried out by a qualified dermatologist. The presence or absence of amputation related dermatoses were specifically recorded and treated. At the third visit all the patients who were managed at the last visit were re-evaluated and assessed in relation to the guidelines provided to them. A total of 210 amputees [159 males and 51 females] volunteered for the study and were enrolled. Their ages ranged from 2 years to 85 years. A total of 210 cases 54 [25.7%] persons had skin lesions including ulcers [n=15], contact dermatitis [10 M, 4 F], adherent scars [6 M, 5 F], abrasions [5 M, 4 F], folliculitis [2 M], inclusion cyst [1 M], hypopigmentation [IF] and hyperpigmentation [IF]. Of the total 54 lesions, 31 lesions were seen in lower and 23 lesions were seen in the upper limb. Ulcers were the most common findings followed by allergic contact dermatitis is another significant problem. Measures should be taken to avoid unnecessary trauma and all patients with dermatitis on the residual limb should be patch tested to determine the cause

Esophageal ulcers caused by reactivation of ganglionary tuberculosis: a case report

The involvement of the esophagus in tuberculosis (TB) is extremely rare. This is a case report of an immunocompetent male patient, who presented ganglionary TB reactivation, with the development of extensive esophageal ulcers. The endoscopic approach made the diagnosis possible and there was a total resolution of the symptoms after the treatment.
