BackgroundPrimary chest wall tumors originate from different constructions of thoracic wall. We report our multidisciplinary experience on primary thoracic tumor resection and thoracic reconstruction, the need to additional therapy and evaluating prognostic factors affecting survival.MethodsWe performed a retrospective review of our prospectively maintained database of 40 patients treated for malignant primary chest wall tumor from 1989 to 2009. Patients were evaluated in terms of age, sex, clinical presentation, type of imaging, tissue diagnosis methods, pathology, surgical technique, early complications, hospital mortality, prevalence of recurrence and distant metastases, additional treatment, 3 years survival and factors affecting survival.ResultsMale/Female (F/M) = 1, with median age of 43.72 years. Mass was the most common symptoms and the soft tissue sarcoma was the most common pathology. Resection without reconstruction was performed in 5 patients and Thirty-five patients (87.5%) had extensive resection and reconstruction with rotatory muscular flap, prosthetic mesh and/or cement. Overall, 12.5% (5/40) of patients received neoadjuvant therapy and 75% (30/40) of patients were treated with adjuvant therapy. The 3-year survival rate was 65%. Recurrences occurred in 24 patients (60%), 14 developed local recurrences, and 10 developed distant metastases. The primary treatment modality for both local and distant recurrences was surgical resection; among them, 10 underwent repeated resection, 9 adjuvant therapy and 5 were treated with lung metastasectomy. The most common site of distant metastasis was lung (n = 7). Factors that affected survival were type of pathology and evidence of distant metastasis.ConclusionSurgery with wide margin is the safe and good technique for treatment of primary chest wall tumors with acceptable morbidity and mortality.
Regulatory T cells (Tregs) play an indispensable role in the control of immune responses and induction of peripheral tolerance. Dysregulation of Tregs is involved in the pathogenesis of systemic lupus erythematosus (SLE). Tolerogenic probiotics have shown beneficial effects in the control of autoimmune diseases. We evaluated the prophylactic and therapeutic effects of Lactobacillus delbrueckii and Lactobacillus rhamnosus on Tregs and their related molecules in pristane‐induced lupus mice model. Fifty‐four female BALB/c mice (3–5 weeks) were randomly divided into nine groups. Lupus was induced in all groups using pristane. Prophylactic groups were treated from Day 0 (at the time of pristane injection) and treatment groups were treated 2 months later with L. rhamnosus, L. delbrueckii, mix of both probiotics, and prednisolone. One group was considered as SLE‐induced control group without any treatment. Presence of antinuclear antibodies (ANA), antidouble‐stranded DNA (anti‐dsDNA), antiribonucleoprotein (anti‐RNP), proteinuria, and serum level of creatinine, urea, the expression of forkhead box P3 (Foxp3), interleukin 6 (IL‐6), IL‐10, transforming growth factor β, and the number of Tregs were determined. SLE induction by pristane led to the formation of lipogranuloma, presence of ANA, anti‐dsDNA, and anti‐RNP. Probiotics consumption decreased the level of lipogranuloma, ANA, and anti‐dsDNA. In addition, in probiotics receiving groups, Tregs and the expression level of Foxp3 increased, while IL‐6 decreased. The effect of probiotics in the prophylactic group was more prominent. The results may indicate the effectiveness of L. delbrueckii and L. rhamnosus in the enhancement of Tregs and the decrease of inflammatory cytokines and disease severity in SLE‐induced mice.
Introduction:Complete androgen insensitivity syndrome (previously called testicular feminization) is specified by a 46 XY karyotype and negative sex chromatin, bilateral undescended testes, female genitalia appearance, and lack of mullerian derivatives.Case Presentation:A 28-year-old woman with complete (severe) androgen resistance underwent prophylactic laparoscopic bilateral gonadectomy because of the eventually increased risk of gonadal malignancy. Although the gonads appeared grossly normal, microscopic examination revealed bilateral well differentiated sertoli–leydig cell tumor (SLCT).Discussion:Our Medline search revealed that this is the first reported case of bilateral sertoli–leydig cell tumor (SLCT) in androgen insensitivity syndrome.
Prostate cancer (PC) is one of the most common forms of malignancies and the second cause of cancer death all around the world and the eight causes in Iran. The main portion of PC is adenocarcinoma, in some cases neuroendocrine differentiation occurs. Neuroendocrine prostate cancers (NePCs) incidence varies from 0.5% to 2% of all prostate cancers. Large cell neuroendocrine differentiation is very rare. In this study we presented a 71-year-old man with large cell neuroendocrine carcinoma of the prostate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
