Reliable preoperative staging of cervical cancer is important to evaluate and compare the results of different therapeutic modalities, including, surgical treatment, chemotherapy and radiation therapy. The diagnostic reliability of preoperative staging of cervical cancer by cervical biopsy and endocervical curettage was evaluated by a retrospective diagnostic study. The results of this preoperative staging were compared with the stage of cancer set on the basis of histopathological examination of the samples. Only patients who were clinically staged as early (operable) to the disease stage were included in the study. Postoperative diagnosis in 98 patients was exocervical cancer, in 12 endocervical cancer in 5 it was H-SIL (CIN III), and in 4 patients it was chronic cervicitis. The diagnostic reliability of preoperative staging of cervical cancer by cervical biopsy and endocervical curettage was 76.9%. In order to reduce errors in the staging of cervical cancer, it is advised that it be performed in specialized cancer centers by an experienced oncology gynecologist.

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.

Na početku 21. veka, u vremenu društveno-političkih i ekonomskih previranja, u tadašnjoj Jugoslaviji nije bilo organizovanih naučnih i edukativnih aktivnosti u oblasti ehokardiografije. Zahvaljujući entuzijazmu nekoliko srpskih kardiologa, koji su prepoznali potrebu za promenom, aprila 2001. godine u Beogradu je osnovano ehokardiografsko udruženje, sa ciljem da postavi standarde ehokardiografskog pregleda, podrži naučne aktivnosti u oblasti ehokardiografije i osnaži saradnju sa međunarodnim ehokardiografskim organizacijama. Nakon raspada bivše Jugoslavije, prvobitan naziv «Jugoslovensko ehokardiografsko udruženje» (YUECHO), 2006. godine promenjen je u Ehokardiografsko udruženje Srbije (ECHOS).

The purpose of this study was to evaluate the spectrum of the Waldeyer’s ring tumor pathology. Waldeyer’s ring is a ringed arrangement of lymphoid tissue that surrounds nasopharynx and oropharynx. It consists of a pharyngeal tonsil, two tubal tonsils, two palatinal tonsils in the oropharynx, and lingual tonsil. The tonsils are made of heterogeneous tissues, therefore inside the tonsils proliferations could be neoplastic or reactive nature. The participants in our retrospective research were one thousand one hundred thirty patients with histopathology report of tumors of the Waldeyer’s ring. Seven hundred eleven where male and four hundred nineteen were female. The research was conducted at the Clinic for Otorhinolaryngology and Maxillofacial Surgery of the Clinical Center of Serbia from January 1, 2007 to December 31, 2017. The collected data was analyzed by descriptive and analytical statistic methods. It was found that the highest percent of participants developed reactive follicular hyperplasia (51,2%), 25.9% percent squamocellular carcinoma, 8.4% undifferentiated non keratinizing nasopharyngeal carcinoma, and 8.0% nonHodgkin lymphoma. The most malignant tumors were found among male participants over 60 years of age. The majority of malignant tumors grew in oropharynx. The most common tumor was squamous cell carcinoma.
