Cheek Trauma and Mass Formation Caused by Pricker: Diagnostic Value of Fine Needle Aspiration Cytology in an Interesting Case

Cheek trauma is occurs usually due to effect of carious teeth of this region. It may occur depending on the cheek biting habit also in some cases. Parotid duct injury accompanied by cheek trauma is rare. Objective evaluation and radiological methods are of great importance in the diagnostic process of trauma cases and are usually adequate for diagnosis. The use of fine needle aspiration and determination of diagnosis by this method is extremely rare in such cases. Here, a case of parotid duct injury due to trauma and followed by a mass formation in the cheek region was presented; and the value of fine needle aspiration in the diagnostic process of such cases has been reviewed.

Lipomatous pleomorphic adenoma in the hard palate: Report of a rare case with cyto-histo correlation and review

Pleomorphic adenoma is the most common benign tumor of the salivary glands. They are usually composed of epithelial/myoepithelial cells and chondromyxoid stroma. Extensive lipomatous differentiation is very rare. We report a case of lipomatous pleomorphic adenoma (LPA) that presented with a mass in the hard palate of a 32-year-old woman. The fine-needle aspiration cytology material was reported as benign cytology consistent with adenoma with major adipocytic component. Histopathological examination of the excision material displayed that more than 90% of the tumor was adipocytic in texture, containing scant epithelial and myoepithelial cells and chondromyxoid stromal fragments. Preoperative cytodiagnosis of lipomatous pleomorphic adenoma on FNA is based on cytomorphology intimately associated pleomorphic adenomatous and lipomatous tissue elements. LPA should be on the mental list of the (cyto)pathologist in differential diagnosis of lipomatous tumors or non-tumorous lipomatosis or carcinoma invasion in the adipose tissue of the minor salivary gland of the hard palate

Geç Dönemde Gebeliğin Sonlandırılmasının Bir Nedeni Olarak Dev Antenatal Hidronefroz Fetal Otopsi Olgusu

Geç dönemde gebeliğin sonlandırılması tüm dünyada önemli tıbbi ve etik sorunlar oluşturmaktadır. Bu dönemde gebeliğin sonlandırılması için ciddi tıbbi ve ya sosyal endikasyonların bulunması gerekmektedir. Burada antenatal hidronefroza bağlı annenin isteği ile gebeliğin geç dönemde sonlandırılmasına dair bir olgu sunulmuştur. Antenatal hidronefroz, postnatal dönemde spontan gerileme göstermesi ve tedavi olanaklarının bulunması nedeni ile gebeliğin sonlandırılması için ciddi bir endikasyon oluşturmamaktadır. Özellikle kürtaj komplikasyonlarının sık rastlandığı geç dönem gebeliklerde bu gibi nedenlere dayanarak gebeliğin sonlandırılması risklidir. Bu bakımdan sağlık çalışanlarının anne adayına ve ailesine mevcut hastalık, hastalığın seyri ve tedavisi konusunda yeterli bilgi vermesi önem arz etmektedir.

The morphological changes in renal proximal tubules during E. Coli endotoxemia electron microscopic study

E. coli is a gram-negative bacterium, which is present in normal intestinal microflora and indicates the toxic influence to many cells of the body as well as renal vascular endothelial cells in the kidneys and epithelial cells of proximal and distal renal tubules. The toxic effect of E. coli is related to lipopolysaccharide containing endotoxin placed in their wall. The needle biopsy had been taken from 10 patients (7 females, 3 males) complicated by pain in kidneys and nephrotic syndrome in anamnesis during the E. coli endotoxemia. The Araldite-Epon blocks had been prepared from biopsy materials. The semi- and ultrathin sections obtained from these resin blocks were examined by JEM-1400 Transmission Electron Microscope and the electron micrograms were taken. The titer of E. coli endotoxin was high in the microbiological analysis of the urine of the 10 patients with kidney disease (7 of them were female and 3 male). The mixed infection of E. coli and Salmonella were found in bacteriological analysis of 1 female. Upon the result of toxemic influence of E. coli endotoxin to the epithelial cells of renal tubules, the severe structural abnormalities and necrosis were found. The different results of morphological research of renal structures during the E. coli endotoxemia pointed that there arent same findings in epithelial cells of renal tubules in all patients. Finally, our findings can create a morphological basis for the future molecular investigations of acute endotoxemic kidney injury. [Med-Science 2018; 7(1.000): 151-153

Detailing the Pore Structure of Productive Intervals of Oil Wells Using the Color 3D Imaging

The article describes an approach to expanding the methodology for applying hydraulic fracturing in oil fields by adding the possibilities of 3D modeling with color imaging of the pore structure of the productive intervals of wells. As an applied example, the geological and geophysical section of the productive level of one of the wells of the Moscudinskoye oil field, with known data on the integrated interpretation of the results of well-logging and microcomputer tomography, was chosen. According to well-logging data, the productive reservoir in the analyzed section of the section is characterized by a high degree of heterogeneity. Tomographic studies of a full-size core made it possible to identify four lithotypes here with different pore structure features. Accounting for the identified reservoir heterogeneity, as well as data on the thickness and other characteristics of reservoir properties of individual lithotypes that make up the section, made it possible to significantly increase the detail of the final geological model of the wellbore section. A distinctive feature of this final geological model is the use of the method of enlargement of the initial data array by adding intermediate values that were calculated theoretically. The visibility of the final geological model of the borehole walls is provided by color 3D imaging of the calculated data of the enlarged massif and makes it possible to judge the presence of areas with good and weak fluid conductivity on the lateral surface of the borehole walls. According to this model, intrastratal transverse and longitudinal fluid-conducting “corridors” are observed in the circumwell zone that determine the hydro-dynamic movements of natural and artificial fluids in the space of productive reservoirs

olgu Sunumu/Case Report gingival granular Cell Tumor of the newborn: A Case Report and Review of literature

ABSTRACT The etiology and histogenesis of granular cell tumor are still debated. Granular cell tumor of the newborn is considered to be a different entity than the adult form of this lesion with different immunohistochemical features. We present a case of a rare gingival granular cell tumor in a newborn and review the literature. Gingival granular cell tumor must be clinically differentiated from teratoma, congenital dermoid cyst, congenital fibrosarcoma, hemangioma, lymphangioma, leiomyoma, rhabdomyoma, heterotopic gastrointestinal cyst, congenital cystic choristoma and congenital lipoma. Surface ulceration or pseudoepitheliomatous hyperplasia may lead to confusion with malignancy
