The development of Zemun Hospital in the 19th century was followed by better work conditions and an increasing number of patients. The arrival of doctor Vojislav Subotić to the hospital and his work were key moments in the general improvement of the hospital. Since 1887, the hospital was administered by a society known as „Sisters of Charity of Saint Vincent De Paul“. By the end of 1891, they had constructed a new hospital building.

The 20th century was the most eventful period in the history of Zemun Hospital and it brought many changes. Working through out both world wars, the hospital staff aided those who were wounded or ill, both soldiers and civilians. Throughout this period, the hospital worked in three different countries, under various administrations and owners.

Aim: We present a case of a patient with pneumothorax and subcutaneous emphysema as the first manifestation of miliary tuberculosis. Introduction: Miliary tuberculosis is the result of hematogenous dissemination of Mycobacterium tuberculosis in patients with weak immuno-defensive mechanisms. Pneumothorax and subcutaneous emphysema are possible complications of miliary tuberculosis. Case report: A woman aged 64 years old reported to the regional institution because of breathing difficulties. On the radiograph of the chest, pneumothorax was observed left, and the left thoracic drain was placed. Subcutaneous emphysema and global respiratory insufficiency were reported an hour later after which the patient was transferred to our facility. At the admission the patient was in poor general condition, intubated, hemodynamically unstable, markers of inflammation were elevated with the presence of electrolyte imbalance and severe anemia. On the chest radiogram, there was recorded: pneumothorax left, pneumonia right and generalized subcutaneous emphysema, and thoracal drain that was placed. Intensive therapy had improved the condition of the patient, after which she was extubated. Progression of respiratory insufficiency and lethal outcome occurred on the second day of admission. An autopsy was performed. A macroscopic examination and pathohistological analysis found: massive subcutaneous emphysema in the chest, well-placed thoracal drain, bilateral pleural effusion, bilateral acute tuberculous caverns in the lungs and necrotizing granulomas in: the lungs, liver, spleen and larynx which have led to asphyxiation and aviation outcome. Conclusion: In poorly-fed patients with the development of pneumothorax, subcutaneous emphysema and severe respiratory disorders, it is necessary to suspect tuberculosis.

Aim: Reporting a patient with unusual metastatic site of invasive lobular breast cancer (ILC) as initial presentation of the disease. Introduction: Due to specific growth pattern, ILC rarely forms an apparent tumor, which makes diagnosis very challenging at early stage. ILC is also known for unconventional metastatic spread, with deposits being discovered prior to the primary tumor in 3-10% of cases. Case report: While evaluating renal function in 51-year old female patient hospitalised at the Urology Clinic (Clinical centre of Montenegro), static scintigraphy revealed left kidney functional capacity of 7-8%. Nephrectomy was indicated. Kidney, 11x6x4cm in size, with slightly reduced, paler parenchyma, firmly attached fatty capsule and pyelocaliceal system and ureter of regular gross appearence, was delivered to the Centre for Pathology. Analysis of H E sections revealed chronic pyelonephritis. In a few sections taken from urether, pyelon and subcapsular parts of parenchyma, infiltrates of small, cuboid, atipical cells, mostly arranged in one-cell-thick files, were noted. Immunohistochemistry reveiled strong pozitivity for EMA, CK(ae1/ae3), CK7, estrogen and mammaglobin, with Ki67<10%. A few cells were progesteron positive, while vimentin, CK20 and neuroendocrine markers were negative. ILC metastasis was suspected. ILC, with axillary lymph POSTER SESIJA 66 MATERIA MEDICA • Vol. 34 • Issue 1, suplement 1 • april 2018. node involvement, was confirmed later, although there was no macroscopically apparent tumor in the breast. Tumor cells were estrogen and progesterone positive, HER2 negative, with Ki67 of 3%. Conclusion: While assessing metastatic deposits in unconventional sites in women, primary ILC should be considered. Special diagnostic algorhytm is required for efficient initial detection of the primary tumor.

Introduction: A pleural effusion describes an excess of fluid in the pleural cavity, usually resulting from an imbalance in the normal rate of pleural fluid production or absorption, or both. Pleural effusions are associated with a number of pathological medical conditions. In the vast majority of these cases the cellular response is quite nonspecific and will show varying proportions of mesothelial cells, macrophages, erythrocytes, lymphocytes, neutrophils and other leukocytes. Certain diseases may occasionally show cellular changes in the effusion that will reflect their presence. Examples of these include infections such as tuberculosis, blastomycosis, aspergillosis, viral infections, echinococcosis and cryptococcosis. Noninfectious, nonneoplastic diseases diagnosable by cytopathologic methods include rheumatoid arthritis, luAPSTRAKTI 89 MATERIA MEDICA • Vol. 34 • Issue 1, suplement 1 • april 2018. pus erythematosus, eosinophilic pleural effusion, pleural endometriois and sickle cell disease. In spite of these occasional specific cytopathologic diagnoses which can be rendered for the nonneoplastic diseases named above, the most significant role of cytopathology by far is in the examination of effusion fluid for the presence of cancer cells. Cytologic examination of pleural effusions is an important initial step in management of malignant effusions. Although most patients with a malignant effusion have a known history of cancer, a positive effusion may be the first sign of an unsuspected malignancy. Cytologic examination of a serous effusion may offer the possibility of an early and accurate diagnosis by using a minimal intervention. The presence of pleural effusions typically signals an advanced stage of disease so it is associated with poor prognosis. The accuracy of cytologic examinations of malignant pleural effusion is in high range (from 40% to 87%). Lung, breast, ovarian, and gastrointestinal cancers are most likely to cause malignant effusions. The histologic type of cancer most commonly seen in serous effusions is adenocarcinoma but a variety of other cancers can cause effusions. Less common malignancies are squamous cell carcinoma, small cell carcinoma (SCC), hematopoietic malignancies, melanoma, germ cell tumours and sarcomas. Mesotheliomas often present with recurrent serous effusions. One of the most important diagnostic doubts in pleural effusion analysis is distinguishing adenocarcinoma from mesothelioma and mesothelioma from benign mesothelial cells. In most cases the diagnose is based on regular cytomorphology analysis and immunocytochemistry is necessary in low percent of cases to establish the diagnose. The specimens are collecting by thoracentesis, processing in a routine fashion and staining by hematoxylin-eosin (H&E) and Papanicolaou stain after wet fixation with 95% ethanol and May-Grunwald-Giemsa stain after air drying. It is important to evaluate the same cells when constructing coordinate immunoreactivity pattern for various immunomarkers. Since the same cells cannot be followed on different cytology smears, they are not ideally suited for routine immunocytochemical evaluation of effusion fluids. Serial sections of cell-blocks show the same cells in adjacent levels which allow proper evaluation of the coordinate immunoreactivity pattern. Conclusion: Pleural fluid cytological analysis has important diagnostic role in most cases so primary aim should be to establish the correct diagnosis with minimal investigation. Cytology is the only method by which one may retrieve cells from fluid, often in the absence of solid lessions or when obtaining a biopsy from the latter is more difficult and costly and entails much greater discomfort or risk for the patient. Effusion cytology is important for: primary diagnosis of cancer, staging, diagnosis of recurrence or disease progression. Evaluation of effusion cytology is one of the most challenging areas in diagnostic cytopathology. A remarkably wide cytomorphological spectrum of reactive mesothelial cells overlaps with various benign and malignant processes. Due to these limitations, a significant proportion of effusion fluids are difficult to interpret with objective certainty by cytomorphology alone. The use of immunocytochemical panel of antibodies with combination of high sensitivity and specificy is the only way for precise distinguishing of adenocarcinomas from mesothelioma, especially in cases with scant tumor cells particularly in metastatic disease from well differentiated carcinoma, and reactive mesothelial cells from mesothelioma. Other stains are used to confirm pulmonary origin and should be selected as a complement to the panel once adenocarcinoma is confirmed. Molecular diagnostics are feasable on routine cytopreparations, primary diagnostics as well as molecular monitoring during targeted therapy.

As a consequence of significant development of neurosciences several different scientific fields as neuroeducation, neuroesthetics, nerotheology, neuromarketing etc. had been established. Neuroeconomics is interdisciplinary scientific field that has aim to explain neurological mechanisms of decision making process, mental ability of consideration of several possible alternatives, and ability to follow certain direction of action. Neuroeconomics is based on research methods, techniques and models that are overtaken from neurosciences, but also from cognitive and social psychology, as well as from experimental and behavioral economics. In practical sense, neuroeconomics is mainly involved in situations in which humans are not behaving according to rational model, but rather according to innate and adapted schemes of behavior and due to their strong emotional reaction. In this way, knowledge from the scientific fields of neurology and neurosciences that are obtained mainly by usage of neuroimaging, are used in example to investigate market or to determine functioning of employees in critical situations. This kind of practical approach opens several ethical and legal dilemmas..
