Detection of Bartonella henselae DNA in the blood of patients with livedoid vasculopathy

Abstract Background: Livedoid vasculopathy (LV) manifests as ulcers and atrophic white scars on the lower extremities. The main known etiopathogenesis is hypercoagulability with thrombus formation, followed by inflammation. Thrombophilia, collagen and myeloproliferative diseases may induce LV, but the idiopathic (primary) form predominates. Bartonella spp. may cause intra-endothelial infection and skin manifestations caused by these bacteria may be diverse, including leukocytoclastic vasculitis and ulcers. Objective: The aim of this study was to investigate the presence of bacteremia by Bartonella spp. in patients with difficult-to-control chronic ulcers diagnosed as primary LV. Methods: Questionnaires and molecular tests (conventional PCR, nested PCR and real-time PCR) were applied and liquid and solid cultures were performed in the blood samples and blood clot of 16 LV patients and 32 healthy volunteers. Results: Bartonella henselae DNA was detected in 25% of LV patients and in 12.5% of control subjects but failed to reach statistically significant differences (p = 0.413). Study limitations: Due to the rarity of primary LV, the number of patients studied was small and there was greater exposure of the control group to risk factors for Bartonella spp. infection. Conclusion: Although there was no statistically significant difference between the groups, the DNA of B. henselae was detected in one of every four patients, which reinforces the need to investigate Bartonella spp. in patients with primary LV.

Marjolin ulcer: the importance of early diagnosis and excision / Úlcera de Marjolin: a importância do diagnóstico e excisão precoces

Introduction: Marjolin's ulcer is a rare disease characterized by the malignancy of chronic wounds that present healing disorders, often due to chronic irritation and repetitive trauma in this area. The diagnosis is made mainly through clinical history and histopathological examination. The differential diagnoses of other diseases that course with ulcers must always be researched and ruled out. Method: The present work presents a bibliographic review to elucidate the subject's relevance for medical students, physicians and nurses, to assist in early diagnosis. Results: Nine observational studies were selected to compose the discussion. Conclusion: The most effective treatment for this condition is surgery, and lymph node dissection is suggested in some cases. Chemotherapy has not shown satisfactory results, while radiotherapy is used in selected cases. Given the rapid evolution, tissue damage, and worse prognosis, diagnosis, and excision should be performed early for a better clinical outcome.

Introdução: A úlcera de Marjolin é uma doença rara, caracterizada pela malignização de feridas crônicas que apresentaram distúrbios cicatriciais, muitas vezes devido à irritação crônica e a traumas repetitivos nesta área. O diagnóstico é realizado sobretudo através da história clínica e de exame histopatológico. Os diagnósticos diferenciais de outras doenças que cursam com úlceras devem sempre ser pesquisados e afastados. Método: O presente trabalho apresenta uma revisão bibliográfica, a fim de elucidar a relevância do tema para acadêmicos de medicina, médicos e enfermeiros, com o propósito de auxiliar no diagnóstico precoce. Resultados: Foram selecionados 9 estudos observacionais para compor a discussão.

Screening tool development for hand surgery referrals in systemic sclerosis

Abstract Background Systemic Sclerosis (SSc) patients may need hand surgery. Objective To develop a screening tool for rheumatologists to identify potential candidates with systemic sclerosis for hand surgery, optimizing referrals. Methods A pilot cross-sectional study from January 2015 to December 2016. Sample size: 51 participants. Inclusion criteria: ≥ 18 years old, meeting the 2013 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for SSc and hand impairment. Data collected: age, sex, race, disease duration, SSc subtypes, vasodilator use, skin thickness, finger stiffness, presence of Digital Ulcers (DU) and/or calcinosis, presence of Raynaud's Phenomenon (RP) attacks, health status and disability, disease status, pain intensity and functional status of the hands. Data were analyzed by a multivariate logistic regression model. Results Fulfillment of surgical criteria: 68.8%. The surgical group had higher scores on the HAQ-DI (1.39 vs. 0.96, p =0.032) and CHFS (25.0 vs. 12.0, p =0.005) questionnaires, and a higher frequency of DU (91.43% vs. 18.75%, p <0.0010), calcinosis (60.0% vs. 0.0%, p <0.001), use of vasodilators (100.0% vs. 75.0%, p =0.007) and digital stiffness (28.57% vs. 0.0%, p =0.017). The presence of DU increased the chance of surgical indication by 46.2 times (ORIC 95% = 8.23 to 259.49). The statistical model showed good accuracy (86.3%, p <0.001), sensitivity (91.4%), and specificity (81.2%). Conclusion The presence of DU in SSc could be used as a screening feature for early identification and referral of potential candidates for hand surgery.

Necrotizing fasciitis and fatal septic shock associated with Streptococcus constellatus

ABSTRACT Streptococcus constellatus is usually a benign, commensal bacteria but has increased incidence in blood cultures and abscesses. This pathogenic involvement is most prevalent in individuals with underlying medical conditions, such as solid tumors and type 2 diabetes mellitus, as well as in cases of community-acquired infections. We report a 43-year-old male with a right medial thigh ulcer and necrotic scrotal skin. The wound culture from surgical debridement grew Streptococcus constellatus, and histology was consistent with stage III necrotizing fasciitis. Regardless of etiology, the mortality rate of patients with necrotizing fasciitis is greatly decreased with early intervention and thorough surgical debridement.

Effects and mechanism of pterostilbene on wound healing in diabetic skin ulcer model rats / 中国药房

OBJECTIVE To explore the effects of pterostilbene （PTE） on wound healing in diabetic skin ulcer model rats and its mechanism. METHODS Ten SD rats were grouped into control group； after diabetic skin ulcer model of other rats was induced by giving high-fat and high-sugar diet+intraperitoneal injection of streptozotocin+cutting off the skin and subcutaneous tissue in the marked area of the back， model rats were randomly divided into model group， PTE low-dose group （40 mg/kg）， PTE high-dose group （80 mg/kg）， PTE high-dose+PP2 group （80 mg/kg PTE+2 mg/kg SRC inhibitor PP2）， with 10 rats in each group. On the second day after modeling， the rats in each drug group were intraperitoneally injected with corresponding drug solutions， while the rats in control group and model group were intraperitoneally injected with normal saline， once a day， for 14 consecutive days. The wound healing rate of rats in each group was measured on the 7th and 14th day of administration； the contents of interleukin-1β （IL-1β）， IL-6， tumor necrosis factor-α （TNF-α） and vascular endothelial growth factor （VEGF） in the serum of rats were detected； the pathological changes of wound granulation tissue were observed， and the expressions of SRC/mitogen-activated protein kinase kinase （MEK）/extracellular signal-regulated kinase （ERK） signaling pathway-related proteins in wound granulation tissue were detected. RESULTS Compared with control group， the wound healing rate， serum content of VEGF， the phosphorylation levels of SRC， MEK1/2 and ERK1/2 were decreased significantly （P＜0.05）， while serum contents of IL- 1β， IL-6 and TNF-α were increased significantly （P＜0.05）； there was obvious infiltration of inflammatory cells in the wound granulation tissue， and the number of new blood vessels decreased. Compared with model group， above indexes of PTE low-dose and high-dose groups were improved significantly （P＜0.05）， and the pathological injury of granulation tissue in wound was improved. PP2 significantly reversed the improvement effects of PTE on the above indexes （P＜0.05）. CONCLUSIONS PTE can promote the wound healing of diabetic skin ulcer model rats， the mechanism of which may be related to activating SRC/MEK/ERK signaling pathway.

Guideline for the diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients (version 2023) / 中华创伤杂志

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Vulvar ulcerative cutaneous tuberculosis secondary to genital tract tuberculosis

Abstract Tuberculosis is a chronic infectious disease that gradually poses a certain threat to public health and economic growth. Tuberculosis typically affects the lungs, pleura, and lymph nodes and rarely the skin. Cutaneous tuberculosis manifesting as ulcerated lesions is also rare and often misdiagnosed and missed by clinicians. Here, the authors report a 29-year-old female patient presenting a vulvar ulcer for 10 months, accompanied by irregular menstruation and increased vaginal secretions. After a skin biopsy and endometrial PCR testing, it was finally diagnosed as vulvar ulcerative cutaneous tuberculosis secondary to genital tuberculosis. Antituberculosis treatment was effective. Cutaneous tuberculosis is called a great imitator. In order to facilitate the diagnosis and treatment of tuberculosis by clinicians, the authors systematically reviewed this disease as well.

Bullosis diabeticorum como diagnóstico diferencial de úlcera de membros: relato de caso / Bullosis diabeticorum as a differential diagnosis for limb ulcers: case report

Resumo A bullosis diabeticorum (BD) é uma manifestação cutânea infrequente do diabetes e pode afetar os membros superiores. Caracteriza-se pelo aparecimento espontâneo e indolor de flictenas não inflamatórias de aspecto sanguinolento, que podem evoluir para necrose, requerendo que se faça diagnóstico diferencial com doenças dermatológicas, como porfiria cutânea tarda, pseudoporfiria, epidermólise bolhosa adquirida e penfigoide bolhoso, e doenças vasculares, como vasculites, doença arterial periférica, doença de Buerger, entre outras. Neste relato, descreve-se o caso de um paciente masculino de 77 anos, hipertenso e diabético mal controlado, apresentando aparecimento espontâneo de lesões bolhosas de membros superiores, que evoluíram, após ruptura espontânea, para ulcerosas necróticas. A biópsia da lesão diagnosticou a presença de espessamento hialino de vasos dérmicos e de bolhas subcórneas, compatíveis com o diagnóstico de BD. Após a interrupção do tabagismo e a otimização do controle glicêmico associado a corticoterapia tópica, houve melhora, com cicatrização das lesões. A apresentação da BD em membros superiores é mais rara, sendo necessário o diagnóstico diferencial com outras lesões cutâneas e vasculares.

Abstract Bullosis diabeticorum (BD) is an uncommon cutaneous manifestation of diabetes that can affect the upper limbs. It is characterized by spontaneous and painless non-inflammatory bloody blisters, which can progress to necrosis, requiring differential diagnosis to rule out other dermatological diseases, such as porphyria cutanea tarda, pseudoporphyria, epidermolysis bullosa acquisita, and pemphigoid, and vascular diseases, such as vasculitis, peripheral arterial disease, and Buerger's disease, among others. In this report, we describe a 77-year-old male patient with poorly controlled diabetes and hypertension who presented with spontaneous onset of lesions on the upper limbs, initially with bullous characteristics, progressing to necrotic ulcers after spontaneous rupture. A biopsy revealed hyaline thickening of the dermal vessels and subcorneal bullae, consistent with a diagnosis of BD. After smoking cessation and optimization of glycemia control combined with topical corticosteroid therapy, the condition improved and lesions began to heal. This presentation of BD involving the upper limbs is rare, requiring differential diagnosis to rule out other cutaneous and vascular lesions.

Calcinose distrófica cutânea na doença venosa crônica de membros inferiores / Dystrophic calcinosis cutis in chronic venous disease of the lower limbs

Resumo As úlceras de membros inferiores, secundárias à doença venosa crônica (DVC), constituem um problema significativo de saúde pública no Brasil e representam cerca de 70% do total dessas úlceras. Apesar dos recentes avanços tecnológicos e das diversas opções terapêuticas utilizadas para essas lesões crônicas, existem diversos fatores que podem estar implicados na resistência ao tratamento. A calcificação distrófica cutânea (CDC) é uma condição rara e frequentemente subdiagnosticada, que, quando associada à DVC, pode estar associada à refratariedade no processo cicatricial. Neste artigo, relatamos um caso de CDC em paciente portador de DVC e discutimos a sua etiologia, fisiopatologia e possíveis opções de tratamento.

Abstract Lower limb ulcers secondary to chronic venous disease (CVD) are a significant public health problem in Brazil and account for about 70% of these ulcers. Despite recent technological advances and the various therapeutic options for treatment of these chronic injuries, several factors may be involved in resistance to treatment. Dystrophic calcinosis cutis (DCC) is a rare and often underdiagnosed condition that, when in conjunction with CVD, may be associated with a refractory healing process. In this article, we report a case of DCC in a patient with CVD and discuss its etiology, pathophysiology and possible treatment options.

Lobomycosis: exuberant presentation with malignant transformation

Abstract Lobomycosis is a chronic granulomatous infection caused by the yeast Lacazia loboi, typically found in tropical and subtropical geographical areas. Transmission occurs through traumatic inoculation into the skin, especially in exposed areas, of men who work in contact with the soil. Lesions are restricted to the skin and subcutaneous tissue, with a keloid-like appearance in most cases. The occurrence of squamous cell carcinoma on skin lesions with a long evolution is well known; however, there are scarce reports of lobomycosis that developed into squamous cell carcinoma. The authors report a patient from the Brazilian Amazon region, with lobomycosis and carcinomatous degeneration, with an unfavorable outcome, due to late diagnosis.

Vasculopatía Livedoide, la punta del témpano: a propósito de un caso / Livedoid vasculopathy, the tip of the iceberg: a case report

Resumen La vasculopatía livedoide (VL), es una enfermedad vascular oclusiva que afecta la microvasculatura, se caracteriza por ser recurrente y no inflamatoria. Su incidencia es de 1/100.000 casos por habitantes, afectando en su mayoría a mujeres de edad media. Su patogenia se desconoce, pero se destaca el componente trombótico de la misma, causado por un estado de hipercoagulabilidad, que conduce a la oclusión vascular, debiendo distinguirse una forma primaria y una secundaria.Clínicamente se observan úlceras dolorosas a nivel maleolar que evolucionan progresivamente a una cicatrización atrófica, blanquecina nacarada y estrellada característica.Presentamos un caso clínico en un varón con múltiples comorbilidades y difícil tratamiento, el cual requirió un trabajo multidisciplinario.

Abstract Livedoid vascular disease (VL), is an occlusive vascular disease that affects the microvasculature, is characterized by being recurrent and non-inflammatory. Its incidence is 1 / 100,000 cases per inhabitant, affecting mostly middle-aged women. Its pathogenesis is unknown, but its thrombotic component stands out, caused by a state of hypercoagulability, which leads to vascular occlusion, and a primary and secondary form must be distinguished. Clinically, painful ulcers are observed at the malleolar level, progressing progressively to characteristic atrophic, pearly whitish and starry healing. We present a clinical case in a male with multiple comorbidities and difficult management, which required multidisciplinary work.

Lymphocytic thrombophilic arteritis with lower-limb ulcers

Abstract Lymphocytic thrombophilic arteritis is a recently described entity, histopathologically characterized by lymphocytic vasculitis that affects the arterioles of the dermo-hypodermic junction, associated with deposition of fibrin and a luminal fibrin ring. A 49-year-old female patient presented with achromic maculae and a well-defined ulcer on the medial aspect of the left lower limb. The biopsy showed intense inflammatory infiltrate in the papillary dermis with a predominance of lymphocytes, and medium-caliber vessels surrounded by mononuclear infiltrates in the deep reticular dermis. Masson's trichrome staining showed intense destruction of the muscle layer of the vascular wall and a fibrin ring. Good clinical response was attained with azathioprine. The authors believe that the ulceration might be another clinical presentation or represent an atypical progression of this condition.

Among the 64 patients, ulcers and necrotic purpura were mostly irregular, and occurred on the dorsum of the foot and around the ankle. A total of 40 patients presented with purpuric dermatosis-like lesions, including 32 with pigmented purpura and 4 with telangiectatic purpura. Besides, numbness, tingling and other symptoms of nerve terminal damage occurred in 4 patients.Conclusion:Clinical manifestations of livedoid vasculopathy are diverse, and differential diagnosis is important for patients with generalized livedo reticularis, purpuric dermatosis-like lesions and symptoms such as numbness.

Research progress in amniotic membrane transplantation for diabetic foot management / 中国基层医药

The purpose of this review is to evaluate the promoting effects of amniotic membrane tissue on ulcer healing and investigate the underlying mechanism, providing new ideas for diabetic foot management. A computer-based online search of CNKI, PubMed and other databases to screen multi-center, randomized controlled trials published in high-impact journals using biological dressings, diabetic foot and other search terms. The retrieved data were analyzed and summarized. Amniotic membrane tissue and its derivatives can greatly shorten the time taken for healing of ulcer surface. This occurs possibly because they can promote angiogenesis and neural repair and prevent against infection. Moreover, the new derivatives provide great ease in use. Therefore, amniotic membrane and its derivatives provide a new tool for diabetic foot management.

Analysis of animal models of chronic skin ulcers based on characteristics of clinical symptoms of traditional Chinese and Western medicine / 中国中药杂志

Based on the characteristics of clinical symptoms of chronic skin ulcers in traditional Chinese and Western medicine, the current animal models of skin ulcers are summarized. This article analyzes the advantages and disadvantages of animal models according to the etiology and pathogenesis of chronic skin ulcers, traditional Chinese and Western medicine diagnostic criteria and observation indicators, and eva-luates the agreement between the existing animal models and the characteristics of clinical syndromes of traditional Chinese and Western medicine for chronic skin ulcers. Through analysis and comparison, it is found that most of the existing modeling methods are single-factor animal models, and there are certain gaps in the physiological and pathological characteristics of chronic skin ulcers caused by clinical multi-factors and interactions. Most of the modeling methods are guided by Western medicine. The lack of pathogenic factors of traditional Chinese medicine(TCM) in the process of modeling. Therefore, this article proposes to establish a reasonable quantification standard for chronic skin ulcer animal models, and to establish a combination model of chronic skin ulcer disease with traditional Chinese and Western medicine as the focus of future animal model research.
