Morbidity analysis in a rheumatology clinic by occupation and diagnosis
IzvrÅ”ena je analiza 425 bolesnika sukcesivno pregledanih u ambulantama ReumatoloÅ”kog instituta od strane specijalista reumatologa s namerom da se vidi socijalna i medicinska struktura bolesnika koji se upuÄuju u jednu specijalizovanu reumatoloÅ”ku ustanovu. U radu je analiziran morbiditet te je utvrÄeno da se najveÄi postotak oboljenja odnosi na degenerativne promene kiÄmenog stuba (46 %). Radnici iz udruženog rada imali su ÄeÅ”Äe degenerativne promene u odnosu na ostale ispitanike, ali su reÄe obolevali od zapaljenskog reumatizma. Analizom apsentizma utvrÄeno je da su radnici iz proizvodnog rada procentualno viÅ”e izostajali s posla nego radnici iz administracije. Radnici iz administracije, meÄutim, bili su ÄeÅ”Äe hospitalizovani od radnika iz proizvodnih zanimanja.An analysis of 425 patients referred to the outpatients department of the Institute for Rheumatology was performed with the intention to find out who these patients were from the social and medical point of view. The analysed group was composed of 192 (45 %) men and 233 (55 %) women with the residence in the city of Belgrade and its suburbs (79.5 %), on the territory of SR Serbia (17.9 %) and in the other republics (2.6 %). The patients were referred mostly by general practitioners (205), specialists (150), and health insurance boards (25), with requests for consultative examinations and hospitalization. Out of the total number of 425 patients, 246 were seen for the first time in the department, 82 were on a regular follow-up and 97 patients had been treated earlier in the department. Among the examined patients there were 175 workers, 68 clerks, 21 farmers, 66 housewives, 82 pensioners and 13 students. The majority were diagnosed as having degenerative spine and disc lesions (196), followed by inflammatory rheumatic diseases (77), peripheral osteoarthrosis (52), extra-articular rheumatism (37), miscellaneous rheumatic conditions (9) and normal findings or nonrheumatic diseases (30). Twenty-four patients, who remained undiagnosed, were in need of further medical investigation and follow-up. Out of the 243 patients employed 166 (68.3 %) were on sick leave and 21 were hospitalized for further treatment and examination
Micro Rna-21 Expression Levels in Invasive Breast Carcinoma with a Non-Invasive Component
Invasive ductal carcinomas with a non-invasive component (IDC-DCIS) are classified as a group of invasive breast carcinomas, together with pure invasive ductal carcinomas of the breast (IDC). MicroRNA-21 (miR-21) has been characterized as a factor of breast cancer invasiveness, however the difference in miR-21 expression levels between IDC-DCIS and pure IDC tumors and the correlations with standard diagnostic and prognostic parameters inside the IDC-DCIS group are unknown. Our aim was to determine if miR-21 had the ability to distinguish these two invasive breast cancer groups. Levels of miR-21 expression were measured by a stem-loop quantitative Real-Time PCR (RT-qPCR) method. Expression levels of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (Her-2) and proliferative index Ki-67 were evaluated by immunohistochemistry. IDC-DCIS tumors had significantly lower levels of miR-21 expression in grade 2 (P=0.003, Mann-Whitney U test), ER positive (P=0.025, Mann-Whitney U test) and PR positive tumors (P=0.024, Mann-Whitney U test) than pure IDCs. miR-21 levels showed a different pattern of expression in IDC-DCIS compared to IDC tumors, which is based on the difference in miR-21 expression between Her-2 negative and Her-2 positive IDC-DCIS tumors (P=0.030, Mann-Whitney U test) and high negative correlation of miR-21 levels with PR levels (rho=-0.886, P=0.006, Spearman correlation). According to our results, IDC-DCIS breast carcinomas act in a different manner in pure IDC tumors with regard to the relations between miR-21 expression levels and the standard diagnostic and prognostic parameters, such as Her-2 status, ER and PR status and protein levels
The āSurvivorship Passportā for childhood cancer survivors
Abstract Background: Currently, there are between 300,000 and 500,000 childhood cancer
survivors (CCSs) in Europe. A significant proportion is at high risk, and at least 60% of them
develop adverse health-related outcomes that can appear several years after treatment completion.
Many survivors are unaware of their personal risk, and there seems to be a general lack
of information among healthcare providers about pathophysiology and natural history of
treatment-related complications. This can generate incorrect or delayed diagnosis and treatments
Changes in miR-221/222 Levels in Invasive and In Situ Carcinomas of the Breast: Differences in Association with Estrogen Receptor and TIMP3 Expression Levels
Breast cancer (BC) is a heterogeneous group of diseases that still represents a major cause of death in the female population. MicroRNAs (miRNAs, miRs), such as miR-221 and miR-222, have been shown to be involved in BC pathology by acting via its target genes such as tissue inhibitor of metalloproteinase 3 (TIMP3). The main goals of this study were to find differences in miR-221/222 levels of expression in BC groups based on invasiveness, and to investigate the association with estrogen receptor (ER), TIMP3 messenger RNA (mRNA) levels, and clinicopathological characteristics of patients and tumors. In this study, we measured levels of miR-221/222 in 63 breast tissue samples by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) using TaqMan(A (R)) technology and immunohistochemistry. miR-221/222 levels varied significantly across groups based on invasiveness (P LT 0.001). In in situ tumors, miR-221 and miR-222 were negatively associated with ER (P = 0.001, r = -0.714, and P = 0.013, r = -0.585, respectively). In invasive breast carcinomas associated with non-invasive tumors, miR-222 was inversely associated with ER (P = 0.039, r = -0.620). Pure invasive BCs showed a positive correlation of miR-221 and miR-222 with TIMP3 mRNA levels (P = 0.008, r = 0.508, and P = 0.010, r = 0.497, respectively). An increase in miR-221/222 might be an important event for in situ carcinoma formation, and miR-221/222 may be important molecules that highlight potential differences between invasive breast carcinomas associated with non-invasive and pure invasive BCs
Bone microRNA-21 as surgical stress parameter is associated with third molar postoperative discomfort
Objective: To evaluate an association between bone levels of inflammation/oxidative stress mediators and postoperative discomfort after third molar conventional or piezosurgery. Material and methods: Twenty-six subjects with bilaterally impacted mandibular third molars, who underwent either piezo or conventional surgery, were included in a split-mouth design study. MicroRNA-21 (miR-21) expression, interleukin-1 beta (IL-1Ī²), and vascular endothelial growth factor (VEGF) proteins, as well as superoxide dismutase (SOD) activity in alveolar bone, were evaluated. Pain intensity, the first pain appearance, analgesic first use and total dose taken, trismus, and swelling were clinically recorded. Results: MiR-21 expression was higher while VEGF protein was lower in piezosurgery vs. conventional groups. The differences in IL-1Ī² protein and SOD activity were not significant between groups. The pain intensity on the first day was significantly decreased in piezosurgery group. The first pain appearance and the first analgesic taken were reported sooner in conventional vs. piezosurgical group. Significantly pronounced trismus on the third day following conventional surgery was found. In conventional group, significantly increased trismus was observed on the third compared to the first postoperative day. MiR-21 showed significant correlation with the first pain appearance. Conclusion: Delayed onset of less pronounced postoperative pain after piezosurgical vs. conventional extraction of impacted lower third molar was significantly associated with expression of bone miR-21. Clinical relevance: Alveolar bone miR-21 may reflect surgical stress and is associated with third molar postoperative pain onset
Shaping the military wound: issues surrounding the reconstruction of injured servicemen at the Royal Centre for Defence Medicine
The conflict in Afghanistan has produced injuries similar to those produced from military conflicts for generations. What distinguishes the modern casualty of the conflict in Afghanistan from those of other conflicts is the effectiveness of modern field medical care that has led to individuals surviving with injuries, which would have been immediately fatal even a few years ago. These patients present several challenges to the reconstructive surgeon. These injured individuals present early challenges of massive soft-tissue trauma, unstable physiology, complex bony and soft-tissue defects, unusual infections, limited reconstructive donor sites, peripheral nerve injuries and traumatic amputations. Late challenges to rehabilitation include the development of heterotopic ossification in amputation stumps. This paper outlines the approach taken by the reconstructive team at the Royal Centre for Defence Medicine in managing these most difficult of reconstructive challenges
NUT Carcinoma in Children and Adolescents: The Expert European Standard Clinical Practice Harmonized Recommendations
Background and Aims:
Nuclear protein of the testis (NUT) carcinoma (NC) is a rare and highly aggressive tumor mainly occurring in adolescents and young adults, defined by the presence of a somatic NUTM1 rearrangement. The aim is to establish internationally harmonized consensus recommendations for the diagnosis and treatment of adolescents and young adults with NC in the framework of the European Reference Network for Paediatric Oncology.
Methods:
The European Cooperative Study Group for Pediatric Rare Tumors developed recommendations according to the Consensus Conference Standard Operating procedure methodology and reviewed by external āexperts.ā No evidence of level I to II exists. Recommendations were developed based on published prospective (level III), but more frequently retrospective series (level IV), case reports (level V), and personal expertise (level V). In addition, āstrengthā of recommendations were categorized by grading (grade A to E).
Results:
Histology is mandatory for the diagnosis of NC, including immunolabeling with anti-NUT antibodies and molecular biology (NUTM1 rearrangement) (level V; grade A). Treatment of NC usually combines aggressive approaches in multimodal regimens. Chemotherapy should be considered as first-line treatment (neoadjuvant vincristine-adriamycin-ifosfamide/cisplatin-adriamycin-ifsofamide or vincristine-doxorubicin-cyclophosphamide/ifosfamide-etoposide) for unresectable or metastatic tumor (ie, 3 courses), rapidly followed by local treatment (level IV; grade B). Referral to a specialized surgical oncology center is highly recommended (level V; grade A). In localized NC, a complete microscopic surgical resection should be attempted whenever and as soon as possible, followed by primary irradiation (60 to 70 Gy) and involved lymph nodes area (level IV; grade B). For head and neck tumors, a systematic neck dissection might be considered, even if N0 (level V; grade C). Adjuvant postirradiation chemotherapy is recommended, for a total of 9 to 12 courses (level IV; grade B). For first-line resected tumors, concomitant adjuvant chemotherapy to radiotherapy may be discussed (level IV; grade B). Targeted therapies and immunotherapeutic regimens should be delivered in the setting of prospective trials (level V; grade B)
