[Ab] Resumo:INTRODUCTION: Pulmonary neuroendocrine cells (PNEC) are present in the normal lungs with the incidence of 1 in 2500 epithelial cells. They usually proliferate in the presence of reactive processes related to inflammation and fibrosis of the lung parenchyma. The division of pulmonary neuroendocrine cell hyperplasia proposed by Travis et al. additionally distinguished diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) or proliferation that occurs in people without reactive hyperplasia risk factors. The confirmation of the DIPNECH diagnosis requires staining of biopsy specimens using the immunohistochemical technique for neuroendocrine markers. AIM: The aim of this study is to overview the cases of 5 patients in whom the histopathological DIPNECH diagnosis was made in the process of invasive diagnostics performed at the Department of Thoracic Surgery. The aim of the study is to evaluate typical clinical, functional, radiological and histopathological features of this rare disease syndrome. MATERIAL AND METHODS: In the period from April 2010 to June 2014, five patients with lesions in the lungs were subjected to invasive diagnostics. Histopathological and immunohistochemical examinations of the collected specimens were used to make the DIPNECH diagnosis in these patients. The natural history of the disease was traced based on a 5-year follow-up in one of the patients. In addition, we analyzed the literature with regard to the described cases. CONCLUSIONS: Thanks to the early diagnosis of non-specific lesions in the lungs, typical carcinoid which develops on the basis of discussed DIPNECH, was found in the resected material in two out of five operated patients. The accurate diagnosis of DIPNECH allows for the implementation of appropriate treatment and channels further management of the patient into the right direction.

[Ab] Resumo:PURPOSE: Persistent human papillomavirus (HPV) infection is associated with the development of certain types of cancer and the dysregulation of microRNAs has been implicated in HPV-associated carcinogenesis. This is the case of microRNA-146a (miR-146a), which is thought to regulate tumor-associated inflammation. We sought to investigate the expression levels of miR-146a during HPV16-mediated carcinogenesis using skin samples from K14-HPV16 transgenic mice which develop the consecutive phases of the carcinogenesis process. METHODS: Female transgenic (HPV ) and wild-type (HPV ) mice were sacrificed at 24-26 weeks-old or 28-30 weeks-old. Chest and ear skin samples from HPV and HPV mice were histologically classified and used for microRNA extraction and quantification by qPCR. RESULTS: Chest skin samples from 24 to 26 weeks-old HPV mice presented diffuse epidermal hyperplasia and only 22.5% showed multifocal dysplasia, while at 28-30 weeks-old all (100.0%) HPV animals showed epidermal dysplasia. All HPV ear skin samples showed carcinoma in situ (CIS). MiR-146a expression levels were higher in HPV compared to HPV mice (p = 0.006). There was also an increase in miR-146a expression in dysplastic skin lesions compared with hyperplasic lesions (p = 0.011). Samples showing CIS had a significant decrease in miR-146a expression when compared to samples showing epidermal hyperplasia (p = 0.018) and epidermal dysplasia (p = 0.009). CONCLUSIONS: These results suggest that HPV16 induces the overexpression of miR-146a in the initial stages of carcinogenesis (hyperplasia and dysplasia), whereas decreases its expression at later stages (CIS). Taken together, these data implicate and suggest different roles of miR-146a in HPV-mediated carcinogenesis.

[Ab] Resumo:Aims: Intimal hyperplasia (IH) is an abnormal response to vessel injury characterized by the dedifferentiation, migration, and proliferation of quiescent vascular smooth muscle cells (VSMC) to form a neointima layer. Vascular connexins (Cx) are involved in the pathophysiology of various vascular diseases, and Cx43, the main Cx expressed in VSMC, has been shown to promote VSMC proliferation and IH. The aim of this study was to investigate the participation of another Cx, namely Cx37, in the formation of the neointima layer. Methods and results: Wild-type (WT) and Cx37-deficient (Cx37-/-) C57BL/6J mice were subjected to carotid artery ligation (CAL), a model of vessel injury and IH. The neointima developed linearly in WT until 28 days post surgery. In contrast, the neointima layer was almost absent 14 days after surgery in Cx37-/- mice, and twice as more developed after 28 days compared to WT mice. This large neointima formation correlated with a two-fold increase in cell proliferation in the media and neointima regions between 14 and 28 days in Cx37-/- mice compared to WT mice. The CAL triggered Cx43 overexpression in the media and neointima layers of ligated carotids in WT mice, and selectively up-regulated Cx37 expression in the media layer, but not in the neointima layer. The de novo expression of Cx37 in human primary VSMC reduced cell proliferation and P-Akt levels, in association with lower Cx43 levels, whereas Cx43 overexpression increased P-Akt levels. Conclusion: The presence of Cx37 in the media layer of injured arteries restrains VSMC proliferation and limits the development of IH, presumably by interfering with the pro-proliferative effect of Cx43 and the Akt pathway.

[Ab] Resumo:Cholestasis is a condition that leads to chronic hepatobiliary inflammation, fibrosis, and eventually cirrhosis. Many microRNAs (miRs) are known to have a role in fibrosis progression; however, the role of miR-21 during cholestasis remains unknown. Therefore, the aim of this study was to elucidate the role of miR-21 during cholestasis-induced biliary hyperplasia and hepatic fibrosis. Wild-type (WT) and miR-21 mice underwent Sham or bile duct ligation (BDL) for 1 week, before evaluating liver histology, biliary proliferation, hepatic stellate cell (HSC) activation, fibrotic response, and small mothers against decapentaplegic 7 (Smad-7) expression. In vitro, immortalized murine biliary cell lines (IMCLs) and human hepatic stellate cell line (hHSC) were treated with either miR-21 inhibitor or control before analyzing proliferation, apoptosis, and fibrotic responses. In vivo, the levels of miR-21 were increased in total liver and cholangiocytes after BDL, and loss of miR-21 decreased the amount of BDL-induced biliary proliferation and intrahepatic biliary mass. In addition, loss of miR-21 decreased BDL-induced HSC activation, collagen deposition, and expression of the fibrotic markers transforming growth factor-ß1 and α-smooth muscle actin. In vitro, IMCL and hHSCs treated with miR-21 inhibitor displayed decreased proliferation and expression of fibrotic markers and enhanced apoptosis when compared with control treated cells. Furthermore, mice lacking miR-21 show increased Smad-7 expression, which may be driving the decrease in biliary hyperplasia and hepatic fibrosis. During cholestatic injury, miR-21 is increased and leads to increased biliary proliferation and hepatic fibrosis. Local modulation of miR-21 may be a therapeutic option for patients with cholestasis.

[Ab] Resumo:Ovarian monitoring requires the determination of serum estradiol and progesterone levels. We investigated whole follicular steroidogenesis under rFSH in medically assisted procreation (MAP: 26 IVF, 24 ICSI) compared to 11 controls (IUI). Estrone, estradiol, Δ4-androstenedione, testosterone, progesterone and 17-hydroxyprogesterone were measured by immunoassay and mass spectrometry except for estrogens. At the start of a spontaneous or induced cycle, steroids levels fluctuated within normal ranges: estradiol (314-585 pmol/L), estrone (165-379 pmol/L) testosterone (1.3-1.6 nmol/L), Δ4-androstenedione (4.5-5.6 nmol/L), 17-hydroxyprogesterone (2.1-2.2 nmol/L) and progesterone (1.8-1.9 nmol/L). 17-hydroxyprogesterone, Δ 4-androstenedione and estradiol predominated. Then estradiol and oestrone levels rise, but less markedly for oestrone in IUI. In MAP, rFSH injections induce a sharp increase in estrogens associated with a rise in 17-hydroxyprogesterone and Δ4-androstenedione levels, disrupting oestrogen/androgen ratios. rFSH stimulation induces an ovarian hyperplasia and Δ4pathway which could become abnormal. Determining 17-hydroxyprogesterone and Δ4-androstenedione levels with LC-MS/MS may therefore be useful in managing recurrent MAP failures.

[Ti] Título:N-oleoylethanolamide suppresses intimal hyperplasia after balloon injury in rats through AMPK/PPARα pathway.

[Ab] Resumo:Vascular smooth muscle cell (VSMC) proliferation and migration are crucial events in the pathological course of restenosis after percutaneous coronary intervention (PCI). N-oleoylethanolamide (OEA) is a bioactive lipid amide released upon dietary fat digestion with many reported actions. However, the effect of OEA on restenosis after vascular injury remains unknown. Here, we investigated the effects of OEA on intimal hyperplasia after balloon injury in vivo, its effect on VSMC proliferation and migration induced by platelet-derived growth factor (PDGF) stimulation in vitro, and the underlying mechanism underlying these effects. The results showed that OEA-treated rats displayed a significant reduction in neointima formation after balloon injury. In cultured VSMCs, treatment with OEA decreased cell proliferation and migration induced by PDGF. OEA treatment both in vivo and in vitro led to an increase in adenosine monophosphate-activated protein kinase (AMPK) phosphorylation and peroxisome proliferator-activated receptor alpha (PPARα), and a decrease in proliferating cell nuclear antigen (PCNA) and cyclinD1 expression. Pharmacological inhibition of AMPK and PPARα reversed the suppressive effects of OEA on VSMC proliferation and migration, suggesting that the suppressive effect of OEA on VSMC proliferation and migration is mediated through the activation of AMPK and PPARα. In conclusion, our present study demonstrated that OEA attenuated neointima formation in response to balloon injury by suppressing SMC proliferation and migration through an AMPK and PPARα-dependent mechanism. Our data suggests that OEA may be a potential therapeutic agent for restenosis after PCI.

[Ab] Resumo:RATIONALE AND AIM: Hemimandibular hyperplasia is characterized by an obvious overgrowth in the size of the mandible on one side, which can extend up to the midline causing facial asymmetry. Surgical resection of the overgrowth depends heavily on the skill and experience of the surgeon. This report describes a novel methodology of applying three-dimensional computer-aided-design and computer-aided-manufacturing principles in improving the outcome of surgery in 2 mandibular hyperplasia patients. METHODOLOGY: Both patients had their cone beam computer tomography (CBCT) scan performed. CMF Pro Plan software (v. 2.1) was used to process the scan data into virtual 3-dimensional models of the maxilla and mandible. Head tilt was adjusted manually by following horizontal reference. Facial asymmetry secondary to mandibular hypertrophy was obvious on frontal and lateral views. Simulation functions were followed including mirror imaging of the unaffected mandibular side into the hyperplastic side and position was optimized by translation and orientation functions. Reconstruction of virtual symmetry was assessed and checked by running 3-dimensional measurements. Then, subtraction functions were used to create a 3-dimensional template defining the outline of the lower mandibular osteotomy needed. Precision of mandibular teeth was enhanced by amalgamating the CBCT scan with e-cast scan of the patient lower teeth. 3-Matic software (v. 10.0) was used in designing cutting guide(s) that define the amount of overgrowth to be resected. The top section of the guide was resting on the teeth hence ensuring stability and accuracy while positioning it. The guide design was exported as an .stl file and printed using in-house 3-dimensional printer in biocompatible resin. CONCLUSION: Three-dimensional technologies of both softwares (CMF Pro Plan and 3-Matic) are accurate and reliable methods in the diagnosis, treatment planning, and designing of cutting guides that optimize surgical correction of hemimandibular hyperplasia at timely and cost-effect manner.

This case report describes a 22-year-old human immunodeficiency virus-positive Caucasian female who presented with a vulval lesion eight weeks after starting antiretroviral treatment. Clinical examination revealed a 2 cm well-demarcated plaque on the outer aspect of the left labium minus. The lesion was tender, no contact bleeding or ulceration present. She was presumptively treated for chancroid and herpes simplex with 500 mg ceftriaxone IM stat, 1 g azithromycin PO stat, and valacyclovir 500 mg BD for five days. The lesion persisted despite treatment, and during follow-up, a punch biopsy was carried out. She was diagnosed with pseudoepitheliomatous hyperplasia of the epidermis. In addition to highlighting this condition that has been previously reported in human immunodeficiency virus/herpes simplex virus co-infection, this case demonstrates that unusual skin presentations must be considered in human immunodeficiency virus-infected individuals and illustrates the importance of biopsy for any non-healing lesions.

[Ab] Resumo:To study the clinicopathologic features of lymphoproliferative disease by lymph node core needle biopsy(CNB)and to evaluate the diagnostic significance of CNB for lymphoproliferative disease. The annual distribution, entity constitute, clinical finding, gross feature, morphologic change, affiliate study and repeat biopsy diagnosis of 1 013 cases of lymph node CNB diagnosed at West China Hospital of Sichuan University from January 2009 to December 2015 were investigated. (1) Proportion of lymph node CNB in total amount of biopsy specimens increased from 0.2% in 2009 to 0.8% in 2015.(2) The study cohort included 471 lymphomas, 12 atypical lymphoid hyperplasia (ALH), 136 suspected lymphomas, 372 benign lesions, and 22 cases of descriptive diagnoses. The most common types were diffuse large B cell lymphoma and T-lymphoblastic lymphoma. (3) Majority of patients were adolescents and children younger than 20 years or the elderly older than 60 years. 53.1% CNB tumor specimen consisted of ≥4 tissue cores and 40.5% were >2 cm in length. (4) 104 CNB cases with previous history of excision biopsy was included 45 carcinomas(no metastatic carcinoma was found), 32 lymphomas for treatment observation.1/14 suspicious lymphomas, 1/1 ALH and 3/22 cases benign lesions were diagnosed as lymphoma by repeat biopsy respectively. (5) 217 CNB cases were diagnosed as lymphoma by subsequent CNB (70), or subsequent excision biopsy (147) including 78.5%(73/93) suspected lymphomas, 5/7 ALH and 32.3%(20/62)benign lesions. Lymph node CNB has certain clinical indications, although limited for the diagnosis of lymphoproliferative disorders. Suspected lymphomas and ALH diagnosed by CNB should be followed by repeat tissue biopsy. For the benign lesions by CNB it does not rule out additional biopsy to further investigate the lesion.
