ObjectiveTo summarize the clinical characteristics of idiopathic granulomatous mastitis (IGM) and its experiences of diagnosis and treatment.
MethodThe clinical data of 33 patients with IGM from January 2005 to December 2014 were analyzed retrospectively.
ResultsThe mean age of the patients was 33 years. The pathological examination showed that 28 patients (85%) were typical granuloma, and 5 patients (15%) were immature granuloma, whom were confirmed after exclusion of other pathogens. Twenty-nine patients were received drugs treatment, among which 21 patients were cured by taking prednisone orally, 6 patients were cured by the combination of prednisone and methotrexate, 2 patients failed to be cured, and 13 patients relapsed after stopping taking medicine. Four patients with abscess ulceration were received surgical treatment, and 2 patients relapsed after the surgery. Fifteen recurrent patients all were took prednisone and methotrexate orally, among which 1 patient stopped taking medicine because of liver function damage, 1 patient was not fully relieved, and other 13 patients were cured again.
ConclusionsThe clinical manifestations of IGM have no specificities. The diagnosis mainly relies on pathological examination. In the early phase of this disease, the treatment method of steroid or combined immunosuppressant has good effects. In case of ulceration and protracted course, surgical treatment should be considered as early as possible.
Objective To explore the mechanism of full-thickness burn wound healing with autoskin grafting in fault hypodermis wound of granulation excision and to evaluate its effect.Methods By the techniques of clinical observation, histopathology, immunohistochemistry,TEM and FCM,we observed changes of the activity andstructure of grafted skin and the granulation tissue,collagnous fiber,microvessels,the ultramicrostructure of fibroblasts and the expression of basic fibroblast growth factor(bFGF) in the base of autoskin grafting in fault hypodermis wound in burned adult minipigs(Group A), and compared with traditional method of autoskingrafting on the basilar fibrous tissue wound of scraped partly granulation being(Group B) and control group (Group C, without treatment except de-fur).Results The grafted skin survived after 3 days of operation, and it had less injury and higher proliferative index(PI) in group A than in group B. The hyperplasiaof granulation tissue and vascular endothelial and the expression of bFGF were more evident in group A. After 5 days, the proliferation of endothelial cells and granulation and the protein synthesis of fibroblasts were more active in groupA, and at this moment, fresh collagen appeared and proliferated more actively in group B. After 7-14 days, epidermic structure and dermic microvascular density became normal gradually, the granulation on grafting base matured and transformed into fibrous connective tissue in group A. The same change deferred about 2 days in group B. After 21 days, the above pathologic change in group A was less than that in group B. After 3060 days of operation, Group A achieved much less contraction and transfiguration than Group B, and the grafted skin was tender and movable. Conclusion Autoskin grafting in fault hypodermis wound of granulation excision has a better effect than traditional operation.
Granulomatous lobular mastitis (GLM) is a rare mastitis disease, which mainly occurs in childbearing period. The etiology, diagnosis and treatment of GLM are still disputed. In recent years, the role of Corynebacterium infection in the pathogenesis of GLM has attracted more and more attention. Cystic neutrophilic granulomatous mastitis (CNGM) has been proposed, and more and more studies have targeted CNGM as a unique subtype of GLM. This article summarizes the published literature on CNGM so far to discuss the research progress in clinicopathological features, microbiological findings, clinical diagnosis and treatment of CNGM.
Abstract To observe the effect of fibroblast growth factor (FGF) on wound healing, 50 mice were divided into 5 groups. On the back of every mouse, 2 wounds were made by operative cuts, one for experiment and the other for control. The wounds of the experimental group were covered with 0.5ml FGF solution (contented FGF 300 μg/ml, heparin 100 μg/ml), whereas the wounds of the control group were covered with 0.5ml 0.9% NaCl solution. All of the wounds were dressed by sterilized gauze, and received the same treatment once a day. After 1,3,5,7,10 days, the mice in every group were sacrificed and the tissues of the wounds were collected and prepared for microscopic examination. The results showed that the capillaries and fibroblasts in the experimental group were markedly increased and reached the peak 2～3 days earlier than those in the control group. It was suggested that FGF promoted the formation of granulation tissue and the wound healing.
ObjectiveTo investigate the research progress of etiology, pathogenesis, diagnosis, differential diagnosis, and treatment of granulomatous lobular mastitis (GLM). MethodA comprehensive analysis was conducted by reviewing the domestic and foreign literatures on GLM and combining with clinical experience. ResultsGLM was a relatively rare chronic inflammatory disease of the breast, and the number of patients had been increasing in recent years. It mainly occured in multiparous women of childbearing age. Clinically, it was characterized by a hard breast mass with or without redness and pain, and severe cases might be accompanied by nodular erythema and arthritis. Bacterial infection, especially Corynebacterium kroppenstedtii and autoimmunity were considered to be the main causes of GLM. The diagnosis of GLM needed to combine with medical history, clinical manifestations, histopathological findings, imaging findings, and laboratory tests. A multidisciplinary team for diagnosis and treatment of GLM should be established to improve the diagnostic accuracy and reduce misdiagnosis. At present, the treatment methods for GLM were mainly conservative treatment and surgical treatment, including follow-up observation, antibiotic treatment, glucocorticoid treatment, immunosuppressive therapy, surgical treatment, traditional Chinese medicine treatment, and combined treatment. ConclusionsAt present, the incidence of GLM is on the rise, but its etiology and pathogenesis are still unclear. The diagnosis needs to combine with many aspects, and it is recommended that the multidisciplinary team could improve the accuracy of diagnosis. There is still no unified standard for the selection and timing of treatment. Clinicians’ experience and patients’ wishes should be taken into account when choosing treatment options in clinical practice. Prospective and high-quality multicenter clinical trials and evidence-based medicine practice are still needed to further improve diagnosis and treatment of GLM.
