Gastrointestinalni stromalni tumor koji oponaša ginekološku patologiju: prikaz slučaja

Diagnosis of gastrointestinal stromal tumors (GISTs) of the terminal part of the small intestine on ultrasound examination can be difficult because of their similarity in appearance to gynecological tumors. We present a case of a 49-year-old asymptomatic female patient with GIST of the small intestine, which presented as a pelvic mass, mimicking an ovarian tumor. Tumor was diagnosed during the control check up and ultrasound gynecological examination. Computed tomography (CT) showed tumor mass in the pelvis on the right and free fluid in the lesser pelvis. During the surgery, exploration of the abdominal cavity displayed tumor of the terminal part of the small intestine (ileum). The uterus and both adnexes were normal. The patient was treated by resection of the terminal part of the small intestine and termino-terminal anastomosis. Immunohistochemical evaluation demonstrated positive vimentin, positive CD117, and negative CD 34. In the presence of a pelvic mass, especially if other unusual anamnestic data are present, the possibility of other than a gynecologic tumor has to be considered.Dijagnozu gastrointestinalnih stromalnih tumora (GIST) završnog dijela tankog crijeva teško je postaviti ultrazvučnim pregledom jer su izgledom nalik ginekološkim tumorima. Opisujemo slučaj 49-godišnje asimptomatične bolesnice s GISTom tankog crijeva koji se prikazuje kao tvorba u zdjelici i oponaša tumor jajnika. Tumor je dijagnosticiran na kontrolnom i ultrazvučnom ginekološkom pregledu. Kompjutorizirana tomografija (CT) otkrila je tumorsku tvorbu u zdjelici i slobodnu tekućinu maloj zdjelici. Pretraživanjem trbušne šupljine tijekom operacije otkriven je tumor završnog dijela tankog crijeva (ileuma). Maternica i adneksi bili su zdravi. Bolesnici je napravljena resekcija završnog dijela tankog crijeva i termino-terminalna anastomoza. Imunohistokemijska analiza pokazala je pozitivnu reakciju na vimentin i CD117; te negativnu na CD 34. Kad je u zdjelici prisutna tvorba; osobito ako su i drugi anamnestički podaci neuobičajeni; treba uzeti u obzir mogućnost da je riječ o nekom drugom; a ne ginekološkom tumoru

Primary Ewing’s Sarcoma of the Kidney: A Case Report

Primary adult Ewing’s sarcoma is a rare entity. They most commonly occur in children and young adults. 6% of them are localized extraosseously. We present a case of a 51 year old patient with primary renal Ewing’s sarcoma and multiple metastases in liver and iliac bone. Patients with metastatic disease are usually treated with aggressive chemotherapy and have a poor outcome. Our patient underwent complete surgical excision of tumour, and was treated with aggressive chemotherapy, respectively. Two and half years after presentation he is well, without any symptoms

Aggressive Intestinal Schwannoma Malignum Mimicking Gynecological Pathology – A Case Report

Primary malignant schwannoma of the small and large intestine is an extremely rare disease. Therefore, we are going to report an aggressive multifocal malignant intestinal schwannoma in a 66-year old female patient, that was primarily diagnosed as the gynecological tumor that, even after the surgical treatment, had a very quickly recurrence. Small intestine tumors may show images similar to an adnexal tumor, so it is difficult to differentiate one from another prior to the surgery. The patient did not suffer from neurofibromatosis type 1 (NF-1), disease that increases occurrence of malignant schwannoma in comparison with general population. These tumors are often diagnosed late, and radical surgical intervention does not guarantee longer survival. After surgical removal of macroscopically visible tumor masses from this patient, tumor formation within one month after the operation had reached the sizes of 83x66 mm and 85x75 mmrespectively, with the occurrence of metastases in the liver, and thereafter the patient died. In differential diagnosis of adnexal tumor small intestine tumor has to be considered, especially if nonspecific symptoms are present

Trendovi kirurškog liječenja bubrežnih novotvorina: rezultati jednog centra u posljednjem desetljeću

The majority of renal neoplasms can be treated surgically using open or minimally- invasive approach. Nephron-sparing surgery should be used when possible, regardless to the operative approach. In this retrospective study, we analyzed surgical trends of operative treatment of renal neoplasms in the period from February 2011 until December 2020. There were a total of 1031 procedures, 703 (68.2%) radical nephrectomies (RN) and 328 (31.8%) partial nephrectomies (PN). Laparoscopic approach was used in 211 (20.5%) (111 PN and 100 RN), while open approach was used in 820 (79.5%) (328 PN and 703 RN) cases. There were 12 procedures performed with the use of cardiopulmonary bypass and hypothermic arrest. The median operative time was 161 minutes for open RN and 158 for open PN, 160 for laparoscopic RN, and 162 for laparoscopic PN. The most common pathology was clear cell carcinoma in 693 (67.3%), papillary carcinoma in 115 (11.2%), chromophobe carcinoma in 67 (6.5%), oncocytoma in 46 (4.5%), and angiomyolipoma in 33 (3.2%) patients. Pathologically, pT1 stage was diagnosed in 56.9%, pT2 in 5.8%, pT3 in 22.4% and pT4 in 1.2% of patients. Regional lymphadenectomy was performed in 354 (34.3%) patients, among which lymph nodes were positive in 40 (11.3%) cases. Surgical margins were positive in 27 cases when PN was performed (8.2%). In conclusion, there was an ongoing raising trend in the number of procedures in general, and also in minimally invasive and nephron-sparing surgery in our study.Većina bubrežnih neoplazma može se liječiti kirurški primjenjujući otvoreni ili minimalno invazivni pristup. Parcijalna nefrektomija (PN) treba biti učinjena, kada je moguće, bez obzira na kirurški pristup. U ovoj retrospektivnoj studiji analizirali smo kirurške trendove u operativnom liječenju bubrežnih neoplazma u razdoblju od veljače 2011. do prosinca 2020. godine. Ukupno je učinjen 1031 zahvat, 703 (68,2%) radikalne nefrektomije (RN) i 211 (20,5%) PN. Učinjeno je 211 (20,5%) laparoskopskih (111 PN i 100 RN) i 820 (79,5%) otvorenih (328 PN i 703 RN) operacija. Dvanaest operacija je zahtijevalo upotrebu hipotermičkog aresta i kardiopulmonalnog premoštenja. Medijan trajanja operacije je bio 161 minutu za otvorenu RN, 158 za otvorenu PN, 160 minuta za laparoskopsku RN i 162 minute za laparoskopsku PN. Najčešća patologija je bila svijetlostanični karcinom u 693 (67,3%), papilarni karcinom u 115 (11,2%), kromofobni karcinom u 67 (6,5%), onkocitom u 46 (4.5%) i angiomiolipom u 33 (3,2%) slučaja. Patološki, stadij pT1 dijagnosticiran je u 56,9%, pT2 u 5,8%, pT3 u 22,4% i pT4 u 1,2% bolesnika. Regionalna limfadenektomija je učinjena u 354 (34,3%) bolesnika, među kojima su limfni čvorovi bili pozitivni u 40 (11,3%) slučajeva. Kirurški rubovi su bili pozitivni u 27 (8,2%) slučajeva nakon PN. Zaključno, vidljiv je trend porasta ukupnog broja zahvata, a također i porast broja minimalno invazivnih i za bubreg poštednih zahvata

Method for Sizing of a PV System for Family Home Using Economic Indicators

This paper presents a method for finding an optimal photovoltaic (PV) system according to Croatian legislation. The PV sizing model, in which a decision on investment is made according to economic indicators, is made using MATLAB Software. Based on the input data, the monthly PV system production is calculated, and electricity price formed. According to the PV system production and electricity price, economic indicators are calculated and obtained as output data. The model input data are solar irradiation, load diagram, PV system costs and market price of electricity while the model output data are PV system production, savings, profit, incomes, Net Present Value (NPV) and Levelized Cost of Electricity (LCOE). The obtained economic indicators are presented graphically and used for decision making on an optimal PV system size. The presented model is applied and presented in a case study

Determination of the organization systems quality level
