Correlations on the protection of personal data and intellectual property rights in medical research.

PURPOSE: International regulations regarding the protection of individuals concerning the processing of personal data and the free movement of such data highlight the need for their systematization and customization, depending on the purpose for which they are collected and used. BACKGROUND: Medical legislation is structured so that the constitutional right to healthcare is guaranteed and at the same time be protected by respecting the right to privacy with respect to identity, physiological state of the person and the way this, by health maneuvers, was restored. European Union (EU) legislation is more and more complex related to the patients' right and also to the General Data Protection Regulation (GDPR). After the Second World War, in all Europe the problem related to the human rights become a sensible one in all countries and become aware the importance of clear rules for protecting people, to develop and protect their rights. CONTENT: The article presents the correlation between personal data and intellectual property right in the field of medical research, one of the most dynamic fields of scientific research both in the field of fundamental and applied research. Dissemination of medical information collected through scientific works is subject to the fact that progress in any field should be encouraged, in order to increase the quality of life while, at the same time, creating a balance between the interests of the researcher and the public interest and the interest of the academic community represented by any person in the situation of recourse to a medical service. CONCLUSIONS: In the context of the EU guidelines and implementation of GDPR starting to 2018, the medical research and the education of scientific researchers in the field has gone into a new stage of the ethical approach.

Diabetic foot - epidemiological and histopathological aspects.

Our study included a total of 259 patients with diabetes, who were admitted to the Department of Plastic Surgery and Reconstructive Microsurgery of the Emergency County Hospital of Pitesti, Romania, in 2016, with the diagnosis of "diabetic foot". Of the 259 patients, 55 (21.23%) were diagnosed with type 1 diabetes, and the remaining 204 (78.77%) were diagnosed with type 2 diabetes; the ratio of type 1∕type 2 diabetes was 1∕3.7. The injuries presented by the patients were osteitis (27.81%), moist gangrene (21.62%), abscesses (18.92%), cellulitis (11.19%), various forms of fasciitis (8.88%), perforating strand (6.18%), and dry gangrene (5.4%). The disease was most commonly diagnosed in males in the rural environment. Most of the patients were in the age group of 61-70 years old. All patients were surgically treated, but 142 (54.82%) patients needed amputations of foot segments (fingers, metatarsal or tarsal bones). The histopathological and immunohistochemical study on excised fragments revealed the existence of a chronic inflammatory process formed mainly from macrophages, mast cells and CD4+ T-lymphocytes.

Ethical dilemmas in communicating bad news following histopathology examination.

PURPOSE: The study proposes an analysis of the ethical aspects that occur in communicating bad news following histopathology laboratory tests in medical practice, in particular in the case of the anatomical pathology diagnosis confirming a medical condition of poor prognosis. BACKGROUND: Over the last decades, the progress of science and technology in the medical field, as well as the explosive increase of specialist information available on the Internet have led to unprecedented ethical issues related to the communication modality of histopathology test results to patients. CONTENT: The paper analyses from an ethical and legislative perspective the main ethical dilemmas that occur when choosing a modality for communicating test results. DISCUSSION AND CONCLUSIONS: While communicating bad news is an essential ability for medical professionals, it should be used within the context of observing the patients' right to decide whether they wish to receive such information or not and their right to their own autonomy, by means of a personalized protocol for communicating bad news in current medical practice.

Peritumoral inflammatory reaction in non-melanoma skin cancers - histological and immunohistochemical study.

Non-melanoma skin cancers (NMSCs) are the most frequent types of cancer in white skin populations, all over the world. In the last 40 years, there was observed a rapid increase of their incidence, because of the UV radiations exposure and weather changes. Although its morbidity is a relatively modest one, the direct social costs of NMSCs are quite substantial due to a high incidence. Due to these reasons, numerous studies try to clarify the etiopathogenic mechanisms of NMSCs, to elaborate treatment and prevention measures. In the last years, a special attention was given to the relation between inflammation and skin cancer. In our study, we performed a histological and immunohistological evaluation of the inflammatory reaction on a number of 73 surgical exeresis pieces coming from the patients diagnosed with NMSCs. Of these, 21 were squamous cell carcinomas (SCCs) and 52 basal cell carcinomas (BCCs). The peritumoral inflammatory reaction in NMSCs was an extremely variable one in intensity and distribution, from one case to another and even from one area to another within the same tumor, thus proving the complexity of the relations between tumor cells and the cells of the immune system. By comparing the intensity of the inflammatory reaction between the two main types of NMSCs, there was observed that in SCCs the inflammatory reaction was more intense in comparison to BCCs. Also, in SCC there was highlighted a more abundant inflammatory infiltrate in poorly differentiated carcinomas, in comparison to the well-differentiated ones. The presence of the immune system cells (T-lymphocytes, macrophages, mast cells) among the tumoral cells, in a direct contact with these, makes us believe that between the two categories of cells there may appear mechanisms of intercellular communication, distinct from the mechanisms of paracrine signaling.

S100-positive dendritic cells in squamous cell laryngeal cancer.

Dendritic cells (DC) are the most potent antigen-presenting cells, and induce antigen-specific immune responses. DC are believed to evolve into tumor-antigen pulsed cells and then to migrate to local lymph nodes, where they activate anti-tumor immune responses. This theory is supported by studies showing that high DC densities are associated with favorable prognosis in some tumor types. In the present study, we evaluated 40 primary and metastatic laryngeal carcinomas for the presence of DC, using immunohistochemistry with the anti-S100 protein antibody. We analyzed the relationship between the degree of infiltration by S100-positive (S100+) DC and prognostic factors, including histological subtype, histological grade, peritumor inflammatory infiltration, and stromal desmoplasia. The results show that in all evaluated laryngeal cancers S100-positive cells were significantly more frequent in the tumor stroma. Primary tumors with nodal metastases showed more significant differences in intraepithelial and stromal DC distribution than tumors without nodal metastases. A significant higher S100+ DC was also noticed in the desmoplasic stroma of lymph nodes. The subtype with keratinization had a significant higher S100-positive cells infiltration than the adenoid÷transitional subtype. The infiltration rate of intraepithelial S100+ DC was much higher in well-differentiated (G1) tumors. No significant correlation between S100-positive cells and peritumoral inflammatory infiltration and stromal desmoplasia was found. In conclusion, dendritic cells need multiple, much more complex investigations. This work should be regarded as a preliminary investigation.

Prevalence and histopathological types of skin carcinomas in Arges County, Romania.

Non-melanoma skin cancers presented a significant incidence increase in the last decades, worldwidely. Even though the impact upon mortality is a relatively low one, through the incidence increase, their impact upon the public healthcare systems is a considerable one. In our study, we evaluated 109 cases of skin carcinomas hospitalized during 2012 in the Department of Plastic Surgery of the Emergency Hospital of Pitesti, Romania, for a surgical treatment. The gender distribution showed slight lesion predominance in women, being recorded 56 (51.38%) tumors in women and 53 (48.62%) in men. The highest incidence of skin carcinomas (75.23%) was recorded in the persons aged over 60-year-old. Of 109 cases of skin carcinomas, 80 (73.4%) carcinomas developed on indignant tegument areas, while 29 (26.6%) on premalignant skin lesions (fiberconjunctive papillomas, keratocantomas, keratosic verrucas). The histopathological study highlighted the fact that of 109 skin carcinomas, 87 (79.82%) were basal cell carcinomas and only 22 (20.18%) were squamous cell carcinomas. The immunohistochemical reaction to 34ßE12 cytokeratin was highly positive in the cells of the basal cell carcinomas and well-differentiated squamous cell carcinomas (except for the "keratosic pearls") and moderately positive in the moderately differentiated squamous cell carcinoma.
