Plasma cells (PC) are the terminally differentiated effector cells of the B-cell lineage. The aim of this review is to integrate relevant data on the phenotype of plasma cells, including reactive and malignant PC. The current World Health Organisation classification of lymphoid neoplasm is based on correlation of their morphologic, histologic, immunophenotypic, genetic and clinical features. The extensive application of imunohistochemistry is necessary in diagnosis of plasma cell neoplasm, but also in determining prognosis as well as in evaluating residual/ relapsing disease. This review focuses on immunohistochemical analysis non-neoplastic and neoplastic plasma cell proliferation in facilitating the diagnosis and highlights the recent advances that have been made with regard to their stratifying.

The major goals of this presentation are to give the updated knowledge of primary heart muscle disease, cardiomyopathies (CMP), their classification, the diagnostic possibilities using endomyocardial biopsy (EMB) and to estimate the value of EMB in the choice of the right therapeutic approach. Despite many controversies, EMB is today a widely accepted method, with low percentage of complications for analysing CMPs, and is considered to be a routine procedure in many cardiological centers. Inspite the fact that we started with the use of EMB in 80’s, it is not performed often today in Belgrade, like many yeras ago (2). It’s difficult to say why ? The CMPs may be subdivided, according to the functional and structural features, into two groups: idiopathic and specific, or primary and secundary. Idipathic group is consisted of 5 subgroups: hypertrophic, dilated, restrictive, arrithmogenic right ventricular CMP and unclassified. Specific CMPs may be subdivided into 8 groups mainly based on etiopathogenetic characteristics: infective, with viral myocarditis as the most common entity, metabolic, including endocrine disorders and infiltration and storage diseases. Deficiency disorders and heart involvement in connective tissue disorders are also included. Granulomas, neoplasms and neuromuscular disorders are also wery often presented with cardiac disfunction and structural abnormalities. Sensitivity and toxic reactions with long list of substances wich may affect the heart are probably the most present today. Finally, the last group represent miscellaneous systemic syndromes with heart affection. EMB has been increasingly used in the diagnosis of CMPs, with special influnce on diagnosis of heart transplant rejection, myocarditis, treatment modalities of different types of myocarditis, with low complication rate, considered effective, usefull and safe procedure.

In this paper we present the experience with 162 consecutive neuromuscular biopsies analyzed in the period from 2009 to 2012. Neuromuscular diseases are a large group of inherited and acquired diseases that are characterized by loss of muscle mass and muscle weakness. Distinguishing myopathies from peripheral neuropathy, diseases of the anterior horn cells of the spinal cord and the diseases of the neuromuscular junction requires careful clinical evaluation, laboratory, neurophysiological and electromyographical examination, radiological tests, muscle biopsy and genetic testing. Muscle biopsy results can solely be interpreted in the context of the above tests. In Serbia, 2009. in Department of Clinical Pathology Clinical Hospital Center Zemun, a decision by the Serbian Ministry of Health, began a routine diagnostic biopsy specimens in the NMB muscles, nerves and skin.

There is no doubt that obstetrics carries high medical liability risk. In many countries, gynecologists-obstetricians who attend childbirths and perform complex obstetric procedures are faced with increasing malpractice insurance premiums and litigation risk. The American College of Obstetricians and Gynecologists (ACOG) publishes its Survey of Professional Liability since 1983, with the objective to analyze the effect that malpractice litigation has had on the practice of obstetrics and gynecology in the United States1. According to the 2003 ACOG survey, 76.3% of the members who answered the questionnaire have been involved in a lawsuit at least once in their professional career; gynecologists/obstetricians have been sued a total of 2.64 times per individual over the course of their careers1,2. In the 2006 ACOG Survey, 89% of respondents indicated that they had been sued during their careers. The average number of claims per obstetrician was 2.6 (3). The ACOG’s 2009 Survey on Professional Liability showed that nearly 91% of gynecologists/obstetricians had experienced at least one liability claim filed against them during their professional careers, with an average of 2.69 claims per physician. In 2009, 62% percent of the total reported claims were for obstetric care as opposed to gynecology, the same as in the 2006 Survey3,4. In the 2003 ACOG survey, fetal monitoring, neurologically impaired children, neonatal death, shoulder dystocia, uterine rupture, and “decision-to-incision” time were identified as clinical factors frequently present in obstetric malpractice cases1. In both 2006 and 2009 Surveys the reasons for claim were neurologically impaired infant (in 31% of cases in both Surveys), stillbirth/neonatal death (with 16 % of cases in both Surveys), and delay or failure in diagnosis (in 11% of cases in 2009 vs. 14% in 2006)3,4. In all the Surveys, neurological impair is the leading cause of the reasons for liability claim, with the cerebral palsy being the most serious damage. The possible etiologies have been discussed for years, and although the damage to neural tissue is undebatable, there is still no agreement upon the timing of the damage. Some authors think that 90% of the cases of cerebral palsy are not due to intrapartum events, while in the opinion of others most of the devastating events occurred in the perinatal period5,6. It is still impossible to firmly determine in each single case whether the hypoxic insult has developed during delivery, in the first few hours after birth, or was already present before the labor began, as a consequence of long lasting hypoxia during pregnancy. Careful gross and histopathological examination of the placenta in chosen cases can elucidate the events that occurred some time before labor, and help to connect and reconstruct the course of disease7,8.

Savremeni svetski stavovi podrazumevaju limfadenektomiju kao terapijsku proceduru koja je integralni deo radikalne hirurgije karcinoma želuca. Ona se izvodi u pokušaju da se hirurgija malignoma učini što radikalnijom. Cilj svake hirurške procedure je potpuno uklanjanje tumora i svakog tkiva koje njime može biti zahvaćeno. Težnja radikalne hirurgije je u eradikaciji maligne bolesti, a limfadenektomija bitno doprinosi ovom cilju. Limfadenekotmija kod gastričnog karcinoma podrazumeva disekciju limfnih nodusa prve, druge grupe, što se smatra standardnom limfadenektomijom D2. Pored hirurškog načina lečenja karcinoma želuca, koji je ostao dominanatan, u poslednje vreme se razvijaju novi modaliteti lečenja želuca. I pored isticanja u prvi plan značaj hirurškog lečenja i sistematske limfadenektomije, kriterijumi koje je dalo Japansko udruženje za gastrični kancer od 2010g. razlikuje i druge modalitete lečenja gastričnog karcinoma. Karcinome želuca možemo tretirati: endoskopski, laparoskopski, klasičnom hirurškom resekcionom operacijom, hemioterapijom (koja može biti preoperativna i postoperativna) i palijativnom hirurgijom. Svaki od ovih modaliteta lečenja utiče na bolji ishod bolesti pacijenata. Izbor adekavtnog tretmana pacijenta sa karcinomom želuca zavisi od stepena uznapredovalosti maligne bolesti.

Pregledom literature utvrdili smo da su primarni tumori slezine u dece jako retrka pojava, a angiom slezine u dece ispod pet godina je jako redak. Mi prikazujemo redak slučaj angioma u donjem polu slezine u dečaka uzrasta pet godina.Detetu je tokom rutinskog ultrazvučno pregleda bubrega nađena masa koja je na CT okarakterisana kao tumor donjeg pola slezine zbog koga je dete operisano. Dete je praćeno dve godine po operaciji. Dijagnoza i opcije lečenja su široko razmatrane. Angiom slezine je redak tumor u odnosu na druge uzroke abdominalnih masa u dece. Konačna dijagnoza je postavljena histopatološkom i imunohistohemijskom analizom od strane dva patologa i glasi: angioma slezine. Primarni tumori slezine u dece se jako retki a naročito angiom. Parcijalna splenektomija ili parcijalna embolizacija slezine su metode izbora kad je moguće kod primarnih tumora slezine u dece.

Karcinom želuca je posle karcinoma kolona najzastupljeniji karcinom gastrointestinalnog trakta. Dijagnostika karcinoma želuca najčešće se bazira na primeni kontrasne radiografije, fiberoptičke endoskopije sa biopsijom i histološkim pregledom preparata. Adekvatna dijagnostika veoma je bitna za precizno preoperativno gradiranje tumora i odabir hirurške intervencije. Pravilno odredjivanje stepena uznapredovalosti maligne bolesti od velike je vaznosti za pravilan tretman pacijenata sa karcinomom želuca. Zapadni hirurzi koriste TNM sisttem klasifikacije tumora dat od strane Američkog komiteta za kancer (AJCC), dok istočni hirurzi i Japanci koriste Japanski sistem klasifikacije koji je inaugurisan 1981.godine. Operativno rešavanje karcinoma želuca je svakako osnovni terapijski postupak u lečenju ovog oboljenja. Pre bilo kakvog operativnog rada, za uspešno operativno rešavanje karcinomatozne lezije potrebna je adekvatna preoperativna priprema pacijenata. Na ovaj način smanjujemo broj postoperativnih komplikacija

The aim of our study was analyzing data on concentrations of hazardous and noxious substances in the soil in Belgrade, identifying the most common pollutants, as well as proposing measures for reducing pollution of the soil in Belgrade. 60 soil samples from 30 locations were sampled and tested. The samples were taken in locations in the zone of sanitary protection Belgrade waterworks, near the roads, land within the municipal environment and land in the industrial zones. Deviations are primarily related to the presence of increased concentrations of nickel in the soil, while increased values of other parameters were registered in individual samples at specific locations. In order to improve the current state of soil pollution in Belgrade and prevent further degradation, it is necessary to continue with the systematic monitoring of soil contamination, and implement measures to minimize pollution of land and measures aimed at rehabilitation of existing pollution.

Preeclampsia is a pregnancy-specific syndrome of unknown etiology and represents multisystem disorder. It is characterized by the increased blood pressure, proteinuria, and edema. Preeclampsia is a great risk for both mother and fetus. Disturbances of the balance between the production of reactive oxygen species antioxidants status is considered to be one of the causes of various pathological conditions of the reproductive system, including preeclampsia. The main objective of this study is to determine the activities of superoxide-dismutase and catalase in peripheral blood erythrocytes of the pregnant women with preeclampsia and healthy pregnant women before delivery and umbilical cord blood erythrocytes of their babies immediately after the delivery. The results showed that the activity of superoxide dismutase in erythrocytes were statistically significantly lower in the group of patients with preeclampsia than in healthy pregnant women, as in the group of their babies compared to the babies of healthy pregnant women. Similarly, catalase activity was significantly lower in women with preeclampsia compared to the controls, as well as in erythrocytes of their babies compared to babies of healthy mothers. An observed difference in the antioxidant enzyme activities suggests a putative association between preeclampsia and decreased antioxidant status. Since the direct application of antioxidants did not give expected results of the data presented indicate the opportunity for the prevention of preeclampsia and alleviation of symptoms by dietary measures and life style changes in the population of pregnant women and women of childbearing age, directy targeting the enzymatic antioxidant system.
