Evaluation of the modified Regnault "B" technique as a standard level II oncoplastic breast-conserving surgery / A módosított Regnault "B" emlomegtartó mutét mint II. szintu standard onkoplasztikus emlosebészeti technika

INTRODUCTION AND AIM: This study aimed to describe the modified Regnault "B" oncoplastic technique as a standard volume-displacement level II oncoplastic breast-conserving surgery and the related clinicopathological study. METHOD: A retrospective, single-centre study was performed between April 2012 and October 2018 involving 215 breast-cancer patients. Patient characteristics and postoperative complications were recorded, and the quality of life was rated by questionnaires. Aesthetic outcomes were evaluated with BCCT.core software and a five-point Likert scale. RESULTS: The mean patient age was 53 years (range: 29-81 years), with a median follow-up of 47 months (range: 7-85 months). The average surgery time was 47 min (range: 35-85 min) and the pathological average size of the tumours was 33 mm (range: 18-58 mm). Due to positive surgical margins, 13 (6%) completion re-excisions and 3 (1.4%) mastectomies were performed. In total, 16 complications (7.4%) were recorded. The median Likert scale score was 4.2, and the median overall aesthetic outcome assessed by BCCT.core was 1.3 points. According to the quality of life questionnaire, average points of the results demonstrated a high level of patient satisfaction. CONCLUSION: In medium- to large-breasted patients, the modified Regnault "B" technique is a safe and repeatable level II volume-displacement oncoplastic breast-conservation technique. This technique allows extended removal (20-50% of breast tissue) of T1-T3 tumours from the upper outer quadrant and the border of outer quadrants of the breast with improved aesthetic results. The advantage of this technique is that contralateral symmetrisation is not required, while disadvantage of this technique is the skin incision on the breast skin envelope that can make some difficulties when completion mastectomy is required with immediate reconstruction.

Culture, Heritage, Art: Navigating Authenticities in Contemporary Hungarian Folk Singing.

In Hungary, the decline of traditional peasant culture and its heritage has prompted urban revivals, leading to the acceptance of traditional Hungarian folk singing as a performing arts genre. Drawing from a series of in-depth interviews, this study shows how contemporary Hungarian folk singers navigate (define, learn, police) different forms of authenticity within the field of folk music. While we find that objectified authenticity - heritagized classification systems - is the dominant form of symbolic capital, the broader symbolic economy of authenticity is complicated by competing definitions of folk singing as, variously, culture, heritage, and art. Third-person authenticity is more highly regarded, but it is more difficult for contemporary urban folk singers to achieve because they were not socialized in peasant communities. Therefore, they use objectified authenticity such as 'original recordings' as a proxy for learning about living folk culture. Although objectified authenticity constrains the agency of artistic expression, it affords discriminatory creativity (choosing one's own repertoire) and rationalized creativity (adapting traditional material to external values and contexts).

Thyrolipoma or thyroid adenolipoma is an extremely rare form of thyroid adenoma, which also contains mature adipose tissue and follicles covered with fibrous capsule. We present the case of the growing cervical lesion of a 52-year-old female with diabetes, which was removed during total thyreoidectomy. Autoimmune thyroiditis, bilateral papillary carcinoma and cervical thyrolipoma have been identified by the histopathological examination of the thyroid gland. Orv Hetil. 2018; 159(25): 1024-1032.

Aurora kinase B expression in breast carcinoma: cell kinetic and genetic aspects.

BACKGROUND: Mitotic deregulations may contribute significantly to cell division errors and the development of aggressive tumor cells. The mitotic kinase Aurora B is essential for chromosome segregation. Its gene is located at 17p13 in close proximity to the TP53 gene. Although the frequent alteration of this locus is well known, the information about the AURKB status and protein expression is limited. METHODS: 50 breast carcinoma cases were evaluated for 17p13 status and chromosome 17 ploidy by FISH and for Aurora B protein by immunohistochemistry. RESULTS: Aurora B protein expression showed a strong correlation with cell proliferation (regression coefficient = 0.77). Therefore, the Aurora B/MIB-1 index was used as a measure of expression, which showed a wide range (1-35%, mean 0.32, SD ± 0.28). A gain in the 17p13 chromosome locus could not be shown while a deletion was stated in 10/50 cases including a subset with TP53 and AURKB codeletion in 6/10 cases. The loss of TP53/AURKB loci strongly correlated with aneusomy (p < 0.0001). CONCLUSION: Elevated Aurora B expression frequently occurs due to an increased cell proliferation rate in breast carcinoma. Codeletion of TP53 and AURKB at 17p13 indicates a concerted mechanism leading to the survival of cell clones with deficient mitotic kinase function which could contribute to the formation of aneuploid cells and an aggressive tumor phenotype.

[Impact of disease progression on health status, quality of life and costs in rheumatoid arthritis in Hungary]. / A betegségprogresszió hatása az egészségi állapotra, életminoségre és költségekre rheumatoid arthritisben Magyarországon.

UNLABELLED: Rheumatoid arthritis (RA) is a chronic, progressive polyarthritis leading to substantial disability. Standardised data on consequences of disease progression are needed for clinical assessments and also for cost-effectiveness models. AIM: To analyse the impact of disease progression on health status, disease specific quality of life and costs in Hungary. METHODS: A cross-sectional survey was performed between April and August, 2004, involving consecutive RA patients of 6 hospital based rheumatology outpatient centres. Self-completed questionnaires were used to assess functional (HAQ) and health status (EQ-5D), quality of life (RAQoL). Disease activity (DAS) and costs were also surveyed, statistical analysis was performed. RESULTS: 255 patients were involved [mean age 55.5 +/- 12.3 years; disease duration 9.0 +/- 9.3 years; HAQ 1.38 +/- 0.76; EQ-5D 0.46 +/- 0.33; RAQoL 16.2 +/- 8.1; DAS 5.09 +/- 1.42; costs 1,043,163 (+/- 844,750) HUF/patient/year, conversion 1 Euro = 250 HUF]. Correlation was significant between the parameters ( p < 0.01): EQ-5D index = 1.014 - 0.25 x HAQ-0.041 x DAS; HAQ = 0.314 + 0.065 x RAQoL. Analysis by disease severity levels (HAQ groups 0.5 difference) revealed that health status worsens (mean EQ-5D: 0.784; 0.576; 0.504; 0.367; 0.211; 0.022) and costs increase (mean 628,280; 888,187; 953,759; 1,291,218; 1,346,112; 1,371,674 HUF/patient/year) with disease progression. Minimally important worsening of functional ability (0.25 HAQ increase) corresponds to -0.0705 EQ-5D and +1.884 RAQoL change. Lower health status difference (EQ-5D -0.05725) was calculated in patients with lower disease activity (DAS < 5.1). CONCLUSIONS: Correlation between disease progression, health status, quality of life and costs does not differ significantly from international results. The amount of costs is much lower in all disease severity levels than in developed European countries. Our study serves baseline data for health economic analysis in RA in Hungary.

Endothelial dysfunction and atherosclerosis in rheumatoid arthritis: a multiparametric analysis using imaging techniques and laboratory markers of inflammation and autoimmunity.

OBJECTIVE: Cardiovascular disease is a leading cause of mortality in rheumatoid arthritis (RA). Endothelial dysfunction often precedes manifest atherosclerosis. We assessed endothelial dysfunction and atherosclerosis in RA in context with laboratory markers. METHODS: Fifty-two patients with RA and 40 matched healthy controls were studied. We assessed common carotid intima-media thickness (ccIMT) and flow- (FMD) and nitroglycerine-mediated vasodilation (NMD). We also assayed numerous immunological and metabolic laboratory markers. RESULTS: FMD was significantly lower in RA (5.32% +/- 4.66%) compared to controls (8.30% +/- 3.96%) (p = 0.001). NMD was preserved in RA. ccIMT was significantly greater in patients with RA (0.63 +/- 0.14 mm) versus controls (0.54 +/- 0.15 mm) (p = 0.012). In patients with RA, ccIMT correlated with FMD% (R = -0.318, p = 0.022), age (R = 0.831, p < 0.001), and anti-dsDNA levels (R = 0.463, p = 0.006). FMD% correlated with serum interferon-gamma (IFN-gamma) levels (R = 0.516, p = 0.014). NMD% correlated inversely with the percentage of Th0 lymphocytes (R = -0.636, p = 0.006), serum immune complex (R = -0.692, p < 0.001), and IgM levels (R = -0.606, p = 0.003). Patients with RA were divided as "low" (< 0.65 mm) versus "high" (> 0.65 mm) ccIMT groups, and into "normal" (> 5%) versus "impaired" (< 5%) FMD% subsets. Low and high ccIMT groups differed significantly in age and serum interleukin 1 (IL-1) and anti-dsDNA levels. RA patients with normal versus impaired FMD% differed significantly in age, disease duration, and serum IFN-gamma levels. Lipoprotein(a) [Lp(a)] also correlated with rheumatoid factor (RF) and C-reactive protein (CRP); homocysteine (HCy) correlated with CRP and correlated inversely with folate and vitamin B12 production. Paraoxonase-1 (PON-1) activity correlated with serum tumor necrosis factor-alpha(TNF-alpha) and IL-6 levels. CONCLUSION: This was a well characterized RA population, where FMD and ccIMT were impaired, indicating early endothelial dysfunction and accelerated atherosclerosis, respectively. RA-related autoimmune-inflammatory mechanisms and metabolic factors including anti-CCP, RF, CRP, circulating immune complexes, IgM, TNF-alpha, IL-6, Th0/Th1 ratio, HCy, folate, vitamin B12, and PON-1 may all be involved in the development of vascular disease in RA. Although ccIMT and FMD, as well as some laboratory factors, have been assessed by other investigators in RA-associated atherosclerosis, our results regarding the possible involvement of anti-CCP, anti-dsDNA, Lp(a), some cytokines, and PON-1 activity are novel. Early determination of FMD% and ccIMT may be useful to assess RA patients with high cardiovascular risk.

Accelerated atherosclerosis in rheumatoid arthritis.

Cardiovascular disease is a leading cause of mortality in rheumatoid arthritis (RA). Endothelial dysfunction often precedes manifest atherosclerosis. Both traditional, Framingham risk factors and inflammation-associated factors are involved in RA-associated atherosclerosis. Among imaging techniques, the early determination of common carotid intima-media thickness (ccIMT), flow-mediated vasodilation (FMD), and nitroglycerine-mediated vasodilation (NMD) may be useful to determine atherosclerosis and endothelial dysfunction. We and others found increased ccIMT and impaired FMD in RA patients. Among immunological and metabolic laboratory markers, anticyclic citrullinated peptide (anti-CCP) antibodies, IgM rheumatoid factor, circulating immune complexes, pro-inflammatory cytokines including tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), Th0/Th1 T cells, homocysteine, dyslipidemia, decreased folate and vitamin B12 production, and impaired paraoxonase activity may all be involved in the development of vascular disease in RA. The early diagnosis of endothelial dysfunction and atherosclerosis, active immunosuppressive treatment, the use of drugs that control atherosclerosis, changes in sedentary lifestyle, and the close follow-up of RA patients may help to minimize cardiovascular risk in these individuals.

Increased production of the soluble tumor-associated antigens CA19-9, CA125, and CA15-3 in rheumatoid arthritis: potential adhesion molecules in synovial inflammation?

Some tumor-associated antigens (TAAs) are expressed on inflammatory cells. We previously detected carcinoembryonic antigen (CEA; CD66) in the rheumatoid (RA) synovium. The production of CEA, CA19-9, CA125, and CA15.3, may be increased in patients with RA, scleroderma, lupus, and Sjögren's syndrome (SS). Some of these TAAs contain sialylated carbohydrate motifs and they are involved in tumor-associated cell adhesion and metastasis. We assessed levels of TAAs in the sera of RA patients and healthy subjects. Serum TAA levels were correlated with disease markers including serum rheumatoid factor (RF), C-reactive protein (CRP), and anti-CCP antibody levels, DAS28, age disease duration. TAAs including CEA, CA15-3, CA72-4, CA125, and CA19-9, and neuron-specific enolase (NSE) were assessed by immunoassay in the sera of 75 patients with RA and 50 age- and sex-matched healthy controls. Normal upper limits for these TAAs were 3.4 microg/L, 25 kU/L, 6.9 kU/L, 35 kU/L, 34 kU/L, and 16.3 microg/L, respectively. There were significantly more RA patients showing abnormally high levels of CA125 (10.8% versus 7.1%), CA19-9 (8.1% versus 0%), and CA15-3 (17.6% versus 14.3%) in comparison to controls (P < 0.05). The mean absolute serum levels of CA125 (23.9 +/- 1.8 versus 16.8 +/- 2.2 kU/L) and CA19-9 (14.2 +/- 1.2 versus 10.5 +/- 1.6 kU/L) were also significantly higher in RA compared to controls (P < 0.05). Among RA patients, serum CEA showed significant correlation with RF (r = 0.270; P < 0.05). None of the assessed TAAs showed any correlation with CRP, anti-CCP, DAS28, age or disease duration. The concentration of some TAAs may be elevated in the sera of patients with established RA in comparison to healthy subjects. CEA, CA19-9, CA125, and CA15-3 contain carbohydrate motifs and thus they may be involved in synovitis-associated adhesive events. Furthermore, some TAAs, such as CEA, may also correlate with prognostic factors, such as serum RF levels.

Malignancies and soluble tumor antigens in rheumatic diseases.

Paraneoplastic symptoms, caused by a malignancy, but not directly related to invasion by the tumor or its metastases are the result of a wide variety of tumor-derived biologic mediators like hormones, peptides, antibodies, cytotoxic lymphocytes, autocrine and paracrine mediators. Recognition of paraneoplastic syndromes is important, as it may lead to an early diagnosis of cancer. There is some evidence that systemic inflammatory diseases, such as rheumatoid arthritis (RA), lupus, scleroderma or dermatomyositis may increase the risk for the development of malignancies, predominantly lymphoproliferative disorders. However, reports are somewhat controversial. Immunosuppressive and cytotoxic drugs used in antirheumatic therapy, such as methotrexate, cyclophosphamide, azathioprine or anti-TNF biologicals may also lead to the development of such tumors. Tumor-associated antigens may be produced by inflammatory cells and their production may be increased in RA and other autoimmune diseases.

Suppression of early growth response factor-1 with egr-1 antisense oligodeoxynucleotide aggravates experimental duodenal ulcers.

Previously, we demonstrated that cysteamine releases endothelin-1 in the rat duodenal mucosa, followed by increased expression of early growth response factor-1 (egr-1). We hypothesized that egr-1 is a key mediator gene in the multifactorial mechanisms of duodenal ulcer development and healing because its protein, transcription factor product Egr-1, regulates the expression of angiogenic growth factors. We wanted to determine the effect of egr-1 antisense oligonucleotide on cysteamine-induced duodenal ulcers as well as on the expression of bFGF, PDGF, and VEGF, of which synthesis is modulated by Egr-1. An antisense oligonucleotide to egr-1 was used to inhibit the synthesis of Egr-1 and to determine its effect on ulcer formation in the rat model of cysteamine-induced duodenal ulceration. Real-time RT-PCR and Western blot analysis were used to assess the expression of Egr-1 mRNA and protein as well as ERK, bFGF, PDGF, and VEGF. The antisense Egr-1 oligonucleotide inhibited the expression of egr-1 mRNA and protein and increased the duodenal ulcer size from 8.1 +/- 1.8 mm(2) in controls to 20.7 +/- 4.0 mm(2) (P < 0.01). Cysteamine induced phosphorylation of ERK1/2 and enhanced the synthesis of bFGF, PDGF, and VEGF in the preulcerogenic stages of duodenal ulceration, whereas egr-1 antisense oligonucleotide markedly decreased the expression of these growth factors in the duodenal mucosa. We also demonstrated that Egr-1 expression relates to the ulcerogenic effect of cysteamine because these actions were not exerted by the toxic analog ethanolamine. Thus Egr-1 seems to play a critical role in duodenal ulceration because Egr-1 downregulation aggravates experimental duodenal ulcers, most likely through the transcriptional inhibition of bFGF, PDGF, and VEGF synthesis.
