RESUMEN

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the role of T- and B-regulatory cells (Tregs and Bregs) in the pathogenesis of idiopathic granulomatous mastitis (IGM). METHODS: This study includes 47 patients with pathologically proven IGM (Group P) and 26 healthy subjects (Group C). The patients in Group P were divided into two groups according to whether their lesions were active (Group PA, n: 21) or in remission (Group PR, n: 26). By using flow-cytometry, the frequencies of CD3+CD4+CD45RA-Foxp3high activated Tregs (aTregs), CD3+CD4+CD45RA-Foxp3low non-suppressive Tregs, CD3+CD4+CD45RA+Foxp3low resting Tregs (rTregs), CD3+CD4+CD25+Foxp3- T-effector cells (Teff), total Tregs and Bregs were analyzed in all subjects. RESULTS: The frequency of the Teff cells was statistically higher in Group P when compared with Group C (p =.004). The Foxp3 expression of Treg cells and the frequency of non-suppressive Tregs in Group P were statistically lower than Group C (p =.032 and p =.02, respectively). In addition, Group PR's Foxp3 expressions were statistically lower than Group C (p =.027); Group PR's aTregs ratio was statistically lower than Group PA (p =.021); and the non-suppressive Tregs ratio of Group PR was lower than both Group PA and Group C (p =.006 and p <.0001). No significant differences were seen Bregs and B cell subsets. CONCLUSION: Significant changes in Foxp3 expression and Treg subsets were seen in patients with active IGM lesion and in remission. This study shows an intrinsic defect of Tregs in patients with IGM.

RESUMEN

Background and aim: This study analyzed peripheral blood lymphocyte subsets to determine their role in the etiopathogenesis of IGM. Materials and methods: This study includes 51 pathologically proven IGM patients (active disease: 26 and in remission: 25) and 28 healthy volunteers. The analyses of lymphocyte subsets were performed by flow cytometric immunophenotyping. Results: The percentage of T helper lymphocyte of all IGM patients were lower than control groups (p = 0.001). Absolute cytotoxic T lymphocyte count (p = 0.03), both percentage (p = 0.035) and absolute count (p = 0.002) of the natural killer cells, and both percentage (p = 0.038) and absolute count (p = 0.008) of natural killer T cells, were higher than the control group. The T helper lymphocyte percentage of the patients with active disease was lower than the control group (p = 0.0003). The absolute cytotoxic T lymphocyte (p = 0.029) and natural killer T cells (p = 0.012) of the patients with active disease were higher than the control group. Conclusion: Idiopathic granulomatous mastitis is defined as a localized form of granulomatous disorders. However, the observed changes in T cells, NK, and NKT cells suggest that there is systemic immune dysregulation in patients with IGM.

RESUMEN

INTRODUCTION: Idiopathic granulomatous mastitis (IGM) is a rare, chronic inflammatory benign breast disease. Although the etiology of this disease is unknown, it has been suggested that hormonal disorders, autoimmunity, smoking, and α1-antitrypsin deficiency may play a role in the etiopathogenesis. The aim is to investigate the changes in cytokine profiles including interleukin (IL)-4, -8, -10, -17, and tumor necrosis factor (TNF)-alpha in patients with IGM. METHODS: Forty-seven patients with pathologically diagnosed IGM and 30 healthy women were included. The cytokines including IL-4, -8, 10, -17, and TNF-alpha were measured by human enzyme-linked immunosorbent assay. RESULTS: The IL-8, IL-10, and IL-17 levels were higher in IGM patients than control group (p = .002; p = .008; and p = .018, respectively). The IL-8 levels of patients with active lesions and in remission were statistically higher than the control group (p = .027 and p = .015, respectively). IL-10 levels of patients in remission were higher than the control group (p = .024). There was no difference in IL-4 and TNF-ɑ levels between all groups. CONCLUSION: These results showed that proinflammatory cytokines including IL-8 and IL-17 have role in pathogenesis of IGM. However, the increased levels of IL-10 in especially patients in remission suggest that it reduces the release of proinflamatory cytokines as well as suppressing their function and activation for controlling IGM. Although IGM is thought to be a surgical disease, these cytokine changes indicate the presence of serious immune dysregulation. This suggests that in the treatment of IGM, treatment needs to evolve from surgery to medical treatment.Key points• The IL-8, IL-10, and IL-17 levels were higher in IGM patients than in control group.• The IL-8 levels of both patients with active lesions and in remission were high.• There was no difference in IL-4 and TNF-ɑ levels between all groups.

RESUMEN

Mastitis is a common condition that predominates during the puerperium. Breast abscesses are less common, however when they do develop, delays in specialist referral may occur due to lack of clear protocols. In secondary care abscesses can be diagnosed by ultrasound scan and in the past the management has been dependent on the receiving surgeon. Management options include aspiration under local anesthetic or more invasive incision and drainage (I&D). Over recent years the availability of bedside/clinic based ultrasound scan has made diagnosis easier and minimally invasive procedures have become the cornerstone of breast abscess management. We review the diagnosis and management of breast infection in the primary and secondary care setting, highlighting the importance of early referral for severe infection/breast abscesses. As a clear guideline on the management of breast infection is lacking, this review provides useful guidance for those who rarely see breast infection to help avoid long-term morbidity.

RESUMEN

OBJECTIVE: There is an increase in the incidence of cancer, and consequently in mortality rates, both in the world and in Turkey. The increase in the incidence and mortality rate of cancer are more prominent in our country as well as in other developing countries. The aim of this workshop was to determine the current status on prevention, screening, early diagnosis and treatment of cancer in our country, to identify related shortcomings, specify solutions and to share these with health system operators, and to aid in implementation of these systems. Developments on palliative care were also evaluated. MATERIALS AND METHODS: The current situation in the practice of clinical oncology, related drawbacks, problems encountered during multidisciplinary approach and their solutions were discussed under several sub-headings during a 3-day meeting organized by the Turkish Ministry of Health (Türkiye Cumhuriyeti Saglik Bakanligi-TCSB) with participation of 16 scientists from Turkey and 6 from abroad, and the conclusions were reported. RESULTS: It is expected that the newly established Turkish Health Institutes Association (Türkiye Saglik Enstitüleri Baskanligi-TÜSEB) and the National Cancer Institute (Ulusal Kanser Enstitüsü) will provide a new framework in the field of oncology. The current positive findings include the increase in the number of scientists who carry out successful trials in oncology both in Turkey and abroad, the implementation of the national cancer registry program by the Cancer Control Department and the breast cancer registry program by the Turkish Federation of Breast Diseases Societies (Türkiye Meme Hastaliklari Dernekleri Federasyonu-TMHDF), and introduction of Cancer Early Diagnosis, Screening, and Training Centers (Kanser Erken Tani, Tarama ve Egitim Merkezi-KETEM) for the application of community-based cancer screening programs. In addition to these, obvious shortcomings related to education, implementation, management and research issues were also determined, and policy and project proposals to address these issues were presented. Collaboration with relevant organizations in the implementation of these studies was supported. CONCLUSION: Both the incidence and mortality rates of cancer are increasing in Turkey. The widespread deficiencies in population-based screening and in effective treatment lead to an increase in delay in diagnosis and mortality. Despite improvements in data recording, screening and treatment over the last 10 years, extensive, organized, population-based screening programs and fully equipped early diagnosis and treatment centers are required. Enhancement of basic cancer epidemiologic, translational, genetic and molecular research studies is essential in our country. Improvements on pain treatment and palliative care of patients with chronic and terminal cancer are also required.

RESUMEN

Admissions records are essential in communicating key information regarding unwell patients and at handover of care. We designed, implemented and evaluated the impact of a standardised surgical clerking proforma on documentation and clinician acceptability in comparison to freehand clerking. A clerking proforma was implemented for all acute general surgical admissions. Documentation was assessed according to 32 criteria based on the Royal College of Surgeons of England guidelines, for admissions before (n = 72) and after (n = 96) implementation. Fisher's exact test and regression analysis were used to compare groups. Surgical team members were surveyed regarding attitudes towards the new proforma. Proforma uptake was 73%. After implementation, documentation increased in 28/32 criteria. This was statistically significant in 17 criteria, including past surgical history (p < 0.01), medication history (p = 0.03), ADLs (p = 0.02), systems review (p < 0.01), blood pressure (p < 0.01), blood results (p = 0.02) and advice given to the patient (p = 0.02). The proforma remained beneficial after regression analysis accounted for differences in time of day, seniority of the doctor and nights or weekends (coefficient = 0.12 [p < 0.01]). 89% of the surgical team felt the form improved quality of documentation and preferred its use to freehand clerking. 94% felt it was beneficial on the post-take ward-round. Audit quality control was also more reliable with the proforma (inter-observer agreement = 99.3% [κ = 0.997]) versus freehand clerking (97.1% [κ = 0.941]). Our study demonstrates that a standardised surgical clerking proformas improves the quantity and quality of documentation in comparison to freehand clerking, is preferred by health professionals and improves reliability of the audit quality control process.
