The belief in the inability of neurogenesis, that is the inability to create new neurons after embryonic and early postnatal development of the central nervous system, was rejected in the mid-nineties, when the existence of neurogenesis in restricted areas of CNS adult mammals, including humans, was discovered.Transplantation of stem cells or their derivatives into respective tissues or organs is considered as one of the most promising remedies for many incurable diseases.In this review, we summarized current knowledge and present and future perspectives andchallenges regarding stem cells treatment for Parkinson's and Alzheimer's disease, as the most common age-related neurodegenerative diseases.

Diabetes mellitus is one of the most common non-communicable chronic diseases, which is the combined action of genetic factors, environmental factors and lifestyle. Specific conditions occur in the oral cavity in the course of diabetes that cause changes in all oral tissues with different symptoms and signs. Increased salivary glucose level is followed by increased accumulation of dental plaque and decreased resistance to noxious agents. The most common oral manifestations in diabetic patients include higher prevalence of periodontal desease, burning mouth syndrome, disruption in salivary flow, opportunistic infections, higher prevalence of denture stomatitis, oral lichen planus, fissured tongue, angular cheilitis etc. Dental interventions in patients with well-controlled diabetes are not different from those applied to nondiabetic patients. Regular monitoring of these patients is required because of the complications that can occur.

Cardiovascular complications are the major cause of mortality and morbidity in children with end-stage renal disease who are treated with chronic hemodialysis Arterial hypertension is a major cardiovascular risk factors in this population. The aim is that children who are on HD displays the prevalence of hypertension, to check arterial pressure before and after HD and displays the correlation with the left ventricle mass (LVM). Method: The study in 20 patients on chronic HD and 20 healthy control group children, blood pressure was measured by sphygmomanometer before and after HD. Also echocardiography were measured left ventricular mass before and after HD and track the correlation of these two parameters. Results: The prevalence of hypertension in children on HD is 62% for significant different compared to the control group (p <0.001) .. TA values of systolic and diastolic significantly lower after HD. (P <0.05). After HD TA values were significantly higher than the value of TA (p <0.05) in healthy children. The prevalence of LVH was 60% in children on HD and statistically be statistically highe then to the control group (p <0.001). The correlation between LVH and increased TA was linear but was not statistically significant in either group of patients. In conclusion: The fact that hypertension does not correlate significantly with left ventricular mass suggests that the increase in LVM except high blood pressure and affect other cardiovascular risk factors.

Primary angle-closure glaucoma (PACG) is highly prevalent in Asian countries, compared with primary open-angle glaucoma (POAG), which is reported predominant disease among Whites and that is the reason for paucity of reports about central corneal thickness (CCT) and corneal curvature (CC) in eyes with PACG in Europe. To determine central corneal thickness, corneal curvature and refractive error in patients with primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG). A total of 288 patients were enrolled into this study; 132 patients with PACG (mean age of 73 ± 7 years) compared with 156 patients with POAG (mean age of 70 ±7 years). The data was collected from all PACG patients who underwent Laser peripheral iridotomy at the Clinic for Eye Diseases, Clinical Center of Serbia in Belgrade between January 2012 and October 2012 and controls with POAG examined in the same period. Data from the right eye was used for analysis. In PACG/POAG mean CCT was 549±38/547±35 µm (p=0.353) and mean radius of corneal curvature (Cr) was 7.92±0.22/7.75±0.29 mm (p=0.003). There was no statistically significant correlation between IOP and mean Cr in PACG (p=0.244 ) and POAG ( p=0.637) while it was in POAG group with refractive error (p=0.005) and CCT (p<0.001). We found that CCT in PACG and POAG group were in normal range and there was no diference between them. Our results showed that the eyes with PACG had the flatter corneas than eyes with POAG and were hyperopic.

Necrotizing otitis externa, also known as malignant type of the inflammatory process, represents an infection of the skin of external hearing canal, a fast development of tissue necrosis and infection spreading to the surrounding structures. Basic clinical characteristics are: strong earache, leaking from ear, granulation findings at the bottom of the hearing canal, the disorder of hearing function and a potential possibility of complications (paralysis of facial nerve, intracranial infections). Mycrobiologically the most present bacerium is Pseudomonas aeruginosa. Other microorganisms that can be isolated are Aspergillus species, Staphylococcus aureus, Proteus mirabilis, Klebsiella oxytoca, Candida parapsilosis. The disease is more common in patients with general diseases, mostly of metabolic nature (diabetes mellitus). The approach to diagnosis and therapy is usually urgent in order to prevent the development of serious complications. This paper shows the results of the analysis of clinical process of malignant otitis in 25 patients from the Clinic of ORL and MFS KCS according to the type of the cause and the development of potentially severe and life threatening complications.

Introduction: Psychogenic non-epileptic seizures represent a paroxysmal event followed by a sudden change of behavior, cognition or consciousness, mostly of short duration, which resemble or can be understood as epileptic seizures. They occur in persons without epilepsy and in patients with epilepsy. They are not associated with abnormal EEG discharges because their cause is a psychic disorder. Case report: A 20-year-old patient has been suffering of occasional “morning short-lasting jerking hand movements, staring and fainting” since the age of 14 years. Beside a symptomatic anamnesis for epilepsy and non-specifically changed standard EEG, antiepileptic therapy (valproate and lamotrigine) was introduced. Because of non-response to antiepileptic therapy, the patient was forwarded for further clinical examination involving video EEG telemetry, which indicated that this was a case of psychogenic non-epileptic seizures. A successive withdrawal of antiepileptic drugs was initiated, and also, a psychologist and psychiatrist were included into treatment, which resulted in the reduction of seizures and improvement of the patient's general condition. Conclusion: Psychogenic non-epileptic seizures represent a frequent diagnostic problem requiring team's work, while the video EEG telemetry is the method of choice for diagnosis.

The most important characteristic of calcium channels is selective regulation of slow incoming stream of calcium into the cell tissue providing the slow increasement of action potential. Such tissues include smooth muscles of blood vessels, cardiocytes and heart noduses (AV and SA node). Different calcuim antagonists have different effects on previous tissues due to their different chemical formula. Verapamile, Nifedipin and Diltiazem are the most frequently used of all. Their commonest characteristic is blocking the calcium channels causing vasodilatation of blood vessels as well as negative inotropic and chronotropic influence. By blocking the incoming calcium through slow channels of myofibrils of smooth muscles, the antagonists of calcium decrease the quantity of available calcium for contraction which causes vasodilatation. The most famous and most frequently used calcium antagonist is Verapamile. In terms of electrophysiology, Verapamile inhibits action potentials of heart noduses, especially the AV node, where the slow incoming of calcium is the most important for depolarization. Prolongation of the efective refractory period of SA node causes the heart frequency decreasement while prolongation of the effective refractory period of AV node slows down the work of chambers in case of flater and fibrillation of atriums. The molecules of calcium-bonding protein called kalmodulin are located in synaptic endings. Each kalmodulin can bond four calcium ions providing transfer into active calcium-kalmodulin complex which activates the kinase protein. Activated kinase protein starts the exocytosis of neurotransmitters into synaptic gap. Apart from activating kinase protein, calciumkalmodulin complex also starts the activity of calcium pump presynaptic membrane which pumps calcium out of presynaptic ending stopping the further exocytosis of neurotransmitters into synaptic gap. Taking into consideration the fact that opening the calcium channels on membrane of presynaptic ending is necessary to free the neurotransmitter out of the vesicle, the aim of our work is to study whether Verapamile has effects on the membrane of presynaptic endings of sympathetic nervous system checking the level of catecholamine in serum. The experiment was conducted in 6 healthy dogs which were, after 10-minute- infusion (0.9% NaCl), treated with intravenous bolus veramapile injections in three occasions, in every 5 minutes, until the first signs of intoxication had appeared. This caused bradycardia, heart rhythm disorder and blood pressure drop. In order to determine the level of catecholamine, blood was taken sequentially, in every 5 minutes, before the new dose of verapamile was given. Verapamile (given intravenous) significantly decreases the concentration of adrenaline and noradrenaline in the serum of dogs.

After the armed conflicts throughout the nineties of the twentieth century occurred in former Yugoslavia, identification of war victims is a challenging task. This paper gives a detailed description of exhumed remains identification process. One of the study objectives has been a comparison between DNA results and traditional forensic identification methods. This paper deals with the identification of human remains that were exhumed in Kosovo and Metohia in the period 2001-2012, belonging to Serbs and other non-Albanian ethnic communities (Montenegrins, Bosniaks, Roma, Gorani, and others), as well as much lower number of Albanians who were also killed during the war and post-war period.The experience of this process and the experience of other countries show that there is a need to organize appropriate services for identification of human remains in Serbia, capable to react effectively in case of mass disaster.

A prominent ear, so called a protruding or “lop” ear, is the most common congenital deformity of the external ear. This deformity persists when the mastoid-helix angle (MHA) is higher than 30 degrees. It is relatively common among the population with the incidence of about 5%. The aim of this study is to present surgical procedure and our results using otoplasty with scoring anterior surface of the auricular cartilage. To analyze objective and subjective surgical procedure effects. Between 2011 and 2014 we treated 28 patients. We found statistically high significance p<0.01 in value mastoid-helix angle (MHA) preoperative and postoperative. In patients with bilateral otoplasty the difference between left and right MHAs after surgical procedure is less than 4 degrees. The difference of head-helix distance (HHD) preoperative and postoperative is statistically important with high significance p<0.05. Preoperative satisfaction by personal appearance was better after surgical procedure p<0.05. Complications occurred in 9 cases (32.4%). Otoplasty by scoring anterior surface of auricular cartilage is safe procedure for correction of prominent ear with excellent results on patient satisfaction by personal appearance. Effect of reducing the MHA and HHD is long lasting.

Astma predstavlja veliki zdravstveni problem širom sveta. Poslednjih decenija je uočen porast u prevalenciji i incidenciji astme u pedijatrijskom uzrastu. To je hronična inflamatorna bolest koja se klinički karakteriše rekurentnim respiratornim simptomima, dispnejom, stezanjem u grudima i kašljem.Simptomi su često praćeni reverzibilnim ograničenjem protoka vazduha kroz disanje puteve. U rutinskoj kliničkoj praksi dijagnostika astme u dečjem uzrastu postavlja se na osnovu anamneze, fizikalnog pregleda, odgovora na bronhodilatatore, alergološkog testiranja i ispitivanja plućnih funkcija. Alergološki testovi su primarna dijagnostička metoda u alergologiji. U kliničkoj dijagnostici se najčešće izvodi prick test (PT), zbog svoje osetljivosti, specifičnosti, reproducibilnosti i dobre korelacije sa nivoom serumskog IgE i bronhijalnom reagibilnošću. Istraživanje je preduzeto s ciljem da se utvrdi učestalost pozitivnog nalaza alergijskih kožnih testova na alergene u dece obolele od astme, obzirom da je alergološko ispitivanje jedan od kriterijuma za postavljanje dijagnoze. Ispitivano je 25-oro dece iz kontrolne grupe i 75-oro dece sa astmom. Podelu na grupe vršili smo prema težini astme i tako oformili tri grupe: deca sa lakom, srednje teškom i teškom astmom. Pozitivne kožne probe uočene su u 44,0% dece u kontrolnoj grupi, 84,0% dece sa lakom astmom, 88,0% dece sa sredenje teškom astmom i kod sve dece sa teškom astmom. Najčešće pozitivne probe su na Dermatophagoides: u grupi dece sa teškom astmom 92,0%, sa srednje teškom astmom 75,0% i sa lakom astmom 63,3%, dok su pozitivni testovi na druge alergene bili zastupljeni u manjem procentu.
