ABSTRACT

Gastric cancer is a widely geographically distributed malignancy with high prevalence, therefore being a serious health problem that needs standardized methods for early diagnosis and treatment. The aim of the study was to evaluate the correlation of some epidemiological and clinical data with the histological features. The study group was made up of 66 patients that underwent surgical removal of the gastric neoplasm, and the pathological exam showed the morphological features of the tumor, as well as the ones of the unaffected mucosal tissue. Topographically, the highest incidence of the tumor was registered in the gastric antrum, but in recent years, an increased incidence of the superior gastric pole localization was recorded. The macroscopic aspects reveal that the ulcerated type 2 Borrmann is the most frequent, and alongside type 3 Borrmann, the ulcer-infiltrative type represents most of the gastric antrum cancers. The analysis of the tumor invasion showed that most carcinomas underwent surgery when the tumor invaded the serosa (pT3) or even the perigastric tissues (pT4). In our research, we chose Goseki's microscopic classification because of its best coverage of the histological heterogeneity of the gastric carcinomas, providing information about the percentage of the cellular and secretory differentiation with direct impact on the invasion of the tumor. In more than 70% of the cases, the patients showed lesions of severe chronic atrophic gastritis of the non-tumor mucosa. Lately, the incidence of Helicobacter pylori has been 5.5%, lower than indicated by mainstream literature. We observed that the incidence of type 3 incomplete intestinal metaplasia, as the most commonly involved factor in the etiopathogenesis of gastric neoplasms, was encountered in 36.3% of the cases, this percentage rising proportionally with age and being frequently associated with antrum tumors. In conclusion, the permanent analysis of the relation between epidemiological data and some histological features might be relevant for the characterization of the tumoral process or the non-tumor gastric mucosa, leading to an evaluation of the prognosis.

ABSTRACT

According to recent data, psoriatic patients have an increased prevalence of non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome, compared with the general population. In some published studies, the severity and presence of psoriasis disease were correlated with the severity of NAFLD. In the current study, we aimed to compare the sensibility and specificity of the non-invasive scores and liver biopsy in determining fibrosis in patients with NAFLD and moderate to severe psoriasis. We performed the scientific research from June 2014-December 2017 and we included 71 patients: 40 patients with NAFLD and 31 patients with moderate to severe psoriasis according to Psoriasis Area and Severity Index (PASI) score and NAFLD, who received Etanercept treatment for at least one year. Based on the clinical and laboratory data, we calculated the following scores for fibrosis: body mass index (BMI), aspartate aminotransferase (AST)∕alanine aminotransferase (ALT) ratio, diabetes (BARD) score, Fibrosis-4 (FIB-4) score, and NAFLD fibrosis score (NFS). For liver biopsy, we used the Menghini technique. By calculating Kendall's test, we also observed a strong direct correlation between the degree of fibrosis and FIB-4 (tau=0.558) and NFS (tau=0.490) scores, with a critical statistical impact, and the lack of a correlation with the BARD score (tau=0.095; p=0.332). The hepatic biopsy allowed the more accurate establishment of the role of the non-invasive tests in the diagnosis of the lesions of steatosis, steatohepatitis, and hepatic fibrosis. The non-invasive tests are most useful for the exclusion of the evolution lesions and for the confirmation of the advanced stages of the disease. Among these, the NFS score proved a high statistically significant correlation (p<0.0001) with the fibrosis histological lesions.

ABSTRACT

Bowen's disease (BD) is a relatively frequent non-melanoma skin cancer occurring mostly in elderly people. Until now, the usual way to establish the diagnosis is histopathological examination of a skin biopsy. Dermoscopy and reflectance confocal microscopy (RCM) are modern alternative methods that can be used as quick and non-invasive diagnostic techniques and as follow-up instruments in cases in which a conservative treatment is chosen for the management of BD. There are no very specific dermoscopic criteria for the diagnosis of this disease, but some dermoscopic features (scaly surface, vascular structures and pigmentation) can be found more frequent and can be helpful for the diagnosis. RCM of BD shows an acanthotic epidermis with two types of targetoid cells: the first, a large cell with bright center and dark peripheral halo, the second, a cell with dark center and a bright rim surrounded by a dark hallo, related with dyskeratotic cells on histological examination. BD management could be improved by using non-invasive, in vivo imaging techniques that allow a fast and easy diagnosis and can be used as follow-up tools. However, larger studies are necessary for the validation of our observations.

ABSTRACT

INTRODUCTION: We conducted a retrospective study on patients who were hospitalized in the Emergency County Hospital of Craiova, Romania, between 2009-2014. We selected 75 patients out of 248 cases of fatty liver disease who underwent liver biopsies performed during surgical procedures for various diagnoses. PATIENTS AND METHODS: We analyzed the patients' data recorded in examination charts: anthropometric parameters [height, weight, body mass index (BMI), abdominal circumference], metabolic lab tests (blood glucose, lipid profile), liver destruction enzymes, imaging examinations (abdominal ultrasound). The pathological study was performed on specimens directly after sampling as well as after staining. RESULTS: After analyzing the results of the histological examination, we grouped our studied patients according to the degree of the liver steatosis: 21 (28%) cases with mild steatosis, 46 (61.33%) cases with moderate disease and eight (10.66%) cases with severe steatosis. The necrotic-inflammatory activity was mild in 28 (37.33%) cases, moderate in 36 (48%) cases and severe in 11 (14.66%) cases. Most of the studied patients exhibited septal fibrosis (45 cases - 60%) and porto-portal and porto-central bridging fibrosis (21 cases - 28%). Septal fibrosis and cirrhosis were recorded in four (5.33%) and five (6.66%) cases, respectively. There was a significant correlation between the degree of the hepatic steatosis, the degree of obesity (as expressed by BMI) and the waist circumference (as a measure of central obesity) - p<0.001. CONCLUSIONS: The non-alcoholic fatty liver disease (NAFLD) was found to be significantly associated with waist circumference, BMI, triglycerides. The liver enzymes are not considered to be sensitive or specific for diagnosing NAFLD. Concerning the association between the steatosis and fibrosis, in our study the septal fibrosis was associate with mild steatosis in most of the cases. Moderate steatosis was mostly associated with septal fibrosis as well as porto-portal and porto-central fibrosis. Severe steatosis was correlated with both porto-portal and porto-central fibrosis and cirrhosis in the majority of cases.

ABSTRACT

Necrobiosis lipoidica (NL) is a rare dermatosis that has been shown to precede the onset of diabetes mellitus in 15% of patients. It is more common in women; the average age of the onset is 30 years. Skin lesions of classic NL begin as a small papule, typically on the bilateral pretibial area. Progressively, these papules become indurated plaques with an atrophic, yellow center and multiple telangiectatic vessels, and brown-violaceous borders. We present the case of a 57-year-old male with type II diabetes mellitus from 2004, class II obesity, hepatosteatosis and metabolic disturbances who presents a disseminated eruption from 2010, formed by indurated plaques with flattened centers and a tendency of atrophy and raised, sharply demarcated, red-violaceous borders, having a variable diameter between 1.5 and 5 cm. The laboratory findings revealed elevated glucose levels between 250 and 300 mg%, high levels of transaminases and lipids. Diagnosis of disseminated necrobiosis lipoidica granuloma annulare-type was histopathologically confirmed. For the treatment, we have used topical corticosteroids and Tacrolimus 0.1% and systemic vasodilators. We consider this rare case interesting because has some peculiarities, as: disseminated lesions extend over the characteristic areas for necrobiosis lipoidica, the characteristic features of lesions similar to granuloma annulare, gender (male) and the onset of the disease over fifth decade.
