  • Purpose: Gastric adenocarcinoma of the fundic gland type (chief cell predominant type) (GA-FG-CCP) was first reported as a rare adenocarcinoma found in the normal fundic mucosa. Recent studies have proposed the possibility that GA-FG-CCPs were also generated in the atrophic mucosa after Helicobacter pylori (HP) eradication therapy. However, little is known on the endoscopic findings of GA-FG-CCP generated in the atrophic mucosa due to its extreme rarity. Materials and Methods: A total of 8 patients who underwent endoscopic submucosal resection and were diagnosed with GA-FG-CCP generated in the HP-uninfected mucosa (4 cases, HP-uninfected group) or HP-eradicated atrophic mucosa (4 cases, HP-eradicated group) were retrospectively analyzed, and their endoscopic findings, including magnifying endoscopy with narrow band imaging (M-NBI), and pathological features were compared. Results: While GA-FG-CCPs in the 2 groups displayed similar macroscopic appearance, M-NBI demonstrated that characteristic microvessels (tapered microvessels like withered branches) were specifically identified in the HP-eradicated group. Pathological investigation revealed that a decreasing number of fundic glands and thinned foveolar epithelium covering tumor ducts were thought to lower the thickness of the covering layer over tumor ducts in the HP-eradicated group. Moreover, dilation of vessels just under the surface of the lesions contributed to the visualization of microvessels by M-NBI. Conclusions: The change in background mucosa due to HP infection influenced the thickness of the covering layer over the tumor ducts and M-NBI finding of GA-FG-CCP.

  • Currently, hospitals and medical practices have a large amount of unstructured information, gathered in time at each ward or practice by physicians in a wide range of medical branches. The data requires processing in order to be able to extract relevant information, which can be used to improve the medical system. It is useful for a physician to have access to a patient's entire medical history when he or she is in an emergency situation, as relevant information can be found about the patient's problems such as: allergies to various medications, personal history, or hereditary collateral conditions etc. If the information exists in a structured form, the detection of diseases based on specific symptoms is much easier, faster and with a higher degree of accuracy. Thus, physicians may investigate certain pathological profiles and conduct cohort clinical trials, including comparing the profile of a particular patient with other similar profiles that already have a confirmed diagnosis. Involving information technology in this field will change so the time which the physicians should spend in front of the computer into a much more beneficial one, providing them with the possibility for more interaction with the patient while listening to the patient's needs. The expert system, described in the paper, is an application for medical diagnostic of the most frequently met conditions, based on logical programming and on the theory of probabilities. The system rationale is a search item in the field basic knowledge on the condition. The web application described in the paper is implemented for the ward of pathological anatomy of a hospital in Romania. It aims to ease the healthcare staff's work, to create a connection of communication at one click between the necessary wards and to reduce the time lost with bureaucratic proceedings. The software (made in PHP programming language, by writing directly in the source code) is developed in order to ease the healthcare staff's activity, being created in a simpler and as elegant way as possible.

  • This study discusses various conflict situations and unexpressed pathological potential in historical regions. In this regard, the issue of alienation of local people due to local identity was raised and the cause was investigated. It explains the structural origins of local alienation that occurred in the process of objectifying a region and forming its identity. The process of alienation of local residents of local identity identified in this paper was divided and explained in three stages: objectification of the region, symbolization of local identity, and religious materialism of local identity. In addition, in the process, the incorporation of the production mode of intellectual work, the separation of producers, and the loss of the subject-centered control ability over these products were pointed out as problematic situations. The study suggests to change the perception of the region and to restore the control of the local people through narrative in relation to this problematic situation. Thus, this thesis asserts that we need to have doubts about the justification for the public good and the basis of the resulting consensus, and that we should be constantly interested in the pathological signs of society around us.

  • A histo-pathogical examination was carried out to evaluate the effect of commercial extruded pellet (EP) and a raw fish moist pellet (MP) diet on the health of juvenile rockfish cultured in marine net-cage for 7 months. Fish were distributed randomly to each net cage as a group of 76,000 fish (initial mean body weight 5.9 g). After 2 months, the hypertrophy or swelling of liver parenchymal cells was identified in most individuals and lasted until 7 months. Livers in EP fed group frequently showed hypertrophic parenchyma and fatty change with occasional atrophic cells. However, after 4 months, lymphocytic infiltration in splenic parenchyma was seen in a number of individuals. In addition, the gastric glandular epithelium was atrophied and in the lumen of renal tubules protozoan parasites were frequently identified but there was no correlation with the type of feed. Moreover, juvenile rockfish on EP diet showed gross and microscopic hypertrophy of the liver which would be due to oversupply of feed. Severe hepatic cellular hypertrophy or swelling could lead to the damage of microcirculation. Especially fatty change and atrophic change of liver could be the result from the damage, which could be responsible for immunological problem. Lymphocytic infiltration of spleen on the MP diet suggests that juvenile rockfish could be frequently exposed to infectious antigens.

  • The causes of disease as well as the mechanisms that result in the presenting signs and symptoms of patients are basic elements in oriental medicine. The location of the disease is the region on which the cause and the nature of the disease acts. Syndrome reflects the cause of the disease and the pathological change and the location of the disease. It is customary to classify the location of the disease into two major categories. First is based on the exterior and interior and the second is based on the five internal organs. Exterior syndrome is caused by the invasion of exopathogen in skin and hair, channels and collaterals. Interior syndrome refers to the syndrome located deeply in the interior of the body such as five internal organs. The location of the disease is very important to distinguish different syndromes in the diagnosis and the treatment of a disease.

  • Spontaneous intracranial epidural hematoma (EDH) due to dural metastasis of hepatocellular carcinoma is very rare. A 53-year-old male patient with hepatocellular carcinoma, who was admitted to the department of oncology, was referred to department of neurosurgery because of sudden mental deterioration to semicoma with papillary anisocoria and decerebrate rigidity after transarterial chemoembolization for hepatoma. Brain computed tomography (CT) revealed large amount of acute EDH with severe midline shifting. An emergent craniotomy and evacuation of EDH was performed. Active bleeding from middle cranial fossa floor was identified. There showed osteolytic change on the middle fossa floor with friable mass-like lesion spreading on the overlying dura suggesting metastasis. Pathological examination revealed anaplastic cells with sinusoidal arrangement which probably led to spontaneous hemorrhage and formation of EDH. As a rare cause of spontaneous EDH, dural metastasis from malignancy should be considered.

  • Fibrous dysplasia (FD) of craniofacial structures is well documented, however, its involvement of the clivus is seldom described. We report a case of clival FD in a young man who presented with headache localized to the occipital area. The radiological studies revealed a monostotic disease confined to the clivus, with typical findings of hypo intensity on magnetic resonance images and ground-glass density on computed tomography. The diagnosis of FD was confirmed on pathological examination of specimens taken through transsphenoidal surgery. The patient showed reduction of symptoms and no change of residual lesion on follow-up imaging taken 2.5 years later after surgery. This study includes clinical aspect, radiographic appearance, differential diagnosis and treatment strategy of this rare skull base lesion.

  • Age-related White Matter Changes (WMC) on Magnetic Resonance Imaging (MRI) are known to appear frequently in Multiple sclerosis (MS) and Alzheimer's disease and to be related to cognitive impairment. The characterization of these WMC is very important to the study of psychology and aging. These changes consist of periventricular and subcortical types, however it is difficult to detect and segment WMC using only intensity-based methods, because their intensity, level IS similar to th~t of the gray matter (GM). In this paper, we propose a new method of segmenting periventricular WMC using K-means clustering and morphological features.

  • Veronica peregrina (Scrophylariaceae) has been widely used as a Korean traditional medicine for the treatment of various pathological conditions including infection, hemorrhage and gastric ulcer. In the current study, we investigated the inhibitory effect of methanolic extracts of V. Peregrina (VPM) on the LPS-mediated nitric oxide (NO) production in mouse (C57BL/6) peritoneal macrophages. NO production was significantly down-regulated by the treatment of VPM dose dependently. To evaluate the mechanism of the inhibitory action of VPM on NO production, we performed iNOS enzyme activity assay and checked the change of inducible nitric oxide synthase (iNOS) levels by Western blotting. Although VPM did not affect iNOS enzyme activity, iNOS protein expression was attenuated by VPM indicating VPM inhibits NO production via suppression of iNOS enzyme expression. In addition, VPM attenuated the expression of another pro-inflammatory mediator such as cyclooxygenase-2 (COX-2) in a dose dependent manner. We also found that VPM can reduce trypsin-induced paw edema in mice. Based on this study, we suggest that V. peregrina may be beneficial in diseases which related to macrophage-mediated inflammatory disorders.

  • The authors report a case of cholesterol granuloma in the sphoid sinus in 54-year old woman, which is probably the first report of cholesterol granuloma arising primarily in the sphenoid sinus apart from the petrous bone. The initial clinical presentations were unilateral decreased visual acuity and facial sensory change. The mass was removed totally via transsphenoidal route and the pathological examination revealed cholesterol clefts and chronic granulomatous changes. The differences between the present case and the previous reports are discussed.
