Clinical and pathological considerations in lumbar herniated disc associated with inflammatory lesions.

Lumbar herniated disc is the most frequent cause for lumbar pain. It is caused by degenerative, macroscopic and microscopic changes of the intervertebral discs. It is a chronic disease, with periods of exacerbation and remission under drug and physiotherapeutic treatment. When the disc lesions are large, with intense symptoms, reduced or impossible movements, with pain radiating to the sciatic nerve trajectory, a surgical treatment is required, to remove the herniated nucleus pulposus and decompress the nerve roots. Patients who present high inflammatory signs, high inflammatory serous markers, may have a longer postoperative recovery period, while the motor recovery may be late and incomplete. We analyzed a group of 24 patients with lumbar herniated disc that required discectomy, with clear inflammatory signs, together with histopathological and immunohistochemical changes present in the herniated disc.

Osteopontin - a biomarker of disease, but also of stage stratification of the functional myocardial contractile deficit by chronic ischaemic heart disease.

The study analyses the significance of the plasmatic values of the OPN dosed to 91 people suffering from diastolic cardiac dysfunction with preserved ejection fraction, thus revealing significant growths of its level compared to the normal value. Despite being a clinical research, its conclusions are a breakthrough, differing from the results of other studies published in the relevant medical literature. We can make this assertion because this study analyses the clinical information given by the circulating values of the OPN, based on experimental models (animals), or on patients with congestive heart failure, which can be identified with the existence of a low systolic flow. The results of our study allow us to assert that the plasmatic values of this glycoprotein lead to its acceptance in the medical practice as a new biomarker that provides indicators regarding the stratification of risk with the patients suffering from heart failure of the diastolic dysfunction type, but whose systolic flow is preserved.

Myeloperoxidase, a possible biomarker for the early diagnosis of cardiac diastolic dysfunction with preserved ejection fraction.

The current study was conducted on a sample of 91 patients diagnosed with diastolic dysfunction (DD) with preserved systolic function caused by a painful chronic ischaemic cardiopathy - angina pectoris stable at the effort. The diagnosis was established following anamnesis, electrocardiogram, and echocardiography. Myeloperoxidase (MPO) serum levels were assessed in all patients and then these values were correlated with some of the echocardiography parameters that proved the mentioned diagnosis. In conclusion, the execution of this investigation triad (electrocardiogram, echocardiography, and MPO) allows: Stratifying the patients depending on the disease risk by early detecting of any possible DD with preserved systolic function. The use of the MPO increased circulating levels as a biomarker for diagnosis and risk due to the statistically significant correlation between those and the results of the other two aforementioned paraclinical 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.

Clinical and morphological correlations in acute ischemic stroke.

We studied the clinical and histopathological changes in twenty-seven cases of acute ischemic stroke, aged between 65 and 75 years. All deaths occurred within 30 days after stroke. The aim of our study was to establish the clinical and histological correlations in acute ischemic stroke to detect prognostic factors. Brain lesions after acute stroke were observed in all regions. Our study describes the heterogeneity of brain injury after acute ischemic stroke with the participation of all brain components and the chronology in which these lesions develop and evolve. By histological and immunohistochemical studies, we identified neuronal, glial and vascular damage. The neurons had undergone in the area of lesion a process of necrosis, ballooning or condensation process. In the ischemic penumbra, we observed the presence of red neurons. Vascular lesions were represented by the discontinuity of capillaries, always associated with a marked perivascular edema. The following clinical and morphological correlations were established: liquefactive necrosis, astrocyte gliosis, phagocytosis phenomena are the more intense the later the death of the patient; apoptosis phenomena are the more intense the faster the death of the patient; the entire cerebral microcirculation presented microscopic modifications following the ischemic strokes, regardless of the time since the lesion occurred and the histological examination was made; the major neurological complications of the ischemic stroke - the hemorrhagic transformation phenomena, cerebral edema, were microscopically objectified, regardless of the time since the lesion occurred and the histological examination was made.

Histological and immunohistochemical aspects of cerebral vessels of the elderly.

The central nervous system is considered the most complex morphological structure of the human body. Between nervous tissue and cerebral circulation is a very close relationship, so transient vascular meningocerebral disturbances cause changes in neuronal function clinically expressed as various neurological signs and symptoms, especially in the elderly. In this study, we examined from the histological and immunohistochemical point of view encephalon fragments collected from 24 patients aged between 46 and 85 years. All patients exhibited changes in meningocerebral vessels, ranging from atheromatous plaques to vascular rupture. Immunohistochemical techniques have shown changes in the vascular endothelium, smooth muscle fibers of arterial walls and blood-brain barrier disruption.
