Geologija , 2010,
Abstract: The Trep a Belt of Pb-Zn-Ag mineralization is located within the NNW-SSE trending Vardar zone. The Beltextends for over 80 km, and supported five mines during the period 1930-2008. It contains a number of the otherPb-Zn occurrences too. The replacement and vein type mineralization is hosted primarily by Mesozoic carbonates,but also occasionally by amphibolites, and displays a clear structural control. Mineralization is spatially and geneticallyrelated to Neogene andesite-dacite extrusives and sub-volcanic intrusives. Only Stan Terg mine is presentedin this paper.

Abstract: The aim of this study is to analyze interaction between misclassification rate and w-statistic and to adjust these parameters to be closer to the truth.Analysis of components of TRISS misclassification rate and w-statistic and actual trauma outcome.The component of false negative (FN) (by TRISS method unexpected deaths) has two parts: preventable (Pd) and non-preventable (nonPd) trauma deaths. Pd represents inappropriate trauma care of an institution; otherwise nonpreventable trauma deaths represents errors in TRISS method. Removing patients with preventable trauma deaths we get an Adjusted misclassification rate: (FP + FN - Pd)/N or (b+c-Pd)/N. Substracting nonPd from FN value in w-statistic formula we get an Adjusted w-statistic: [FP-(FN - nonPd)]/N, respectively (FP-Pd)/N, or (b-Pd)/N).Because adjusted formulas clean method from inappropriate trauma care, and clean trauma care from the methods error, TRISS adjusted misclassification rate and adjusted w-statistic gives more realistic results and may be used in researches of trauma outcome.Major trauma is defined as a severe trauma injury when the patient dies in ED or needs major surgical operation on the head, chest, abdomen or inguinal areas or needs immediate ICU admission [1]. If ISS > 15 major trauma is considered. The incidence of major trauma is around 340 – 522 in one million inhabitants per year, and mortality is still high [2,3]. Trauma patients occupy more hospital beds then all patients from heart diseases, and four times more than patients with cancer [4]. Most often are locomotors injuries, but the main cause of death is head trauma [5-7]. Trauma is still the leading cause of deaths of children in industrialized countries [8]. The rate of preventable trauma deaths in the literature is 30% in nontrauma hospitals, and 1 – 5% in trauma centers. In the past two decades of trauma literature the scoring systems issues are very actual; the three most citied articles in the Journal of Trauma are from the fie

Abstract: Introduction: Cholecystitis, for a long time considered as a disease of adults, has had an increased documented incidence of non-haemolitic cholelithiasis in the Pediatric Surgery practice in the last 20 years. Even though diseases of the gall bladder are rare in children, pediatric patients account for 4% of all cases with cholecystectomy. Cholecystitis and other diseases of the gall bladder should be considered in differential diagnosis in every patient with abdominal pain in the right upper quadrant, followed by jaundice, especially in children with history of hemolysis. Aim: The aim is to discuss the diagnostic and therapeutic modalities in 6 children with acute cholecystitis and cholelithiasis diagnosed and treated at the clinic of the authors. Patients and Methods: In the last 5 years, at UCCK, 6 patients under 12 years of age were operated, cholecystectomy was performed. The disease was more prevalent in female patients (66.66%—4 patients) than in male patients (33.33%—2 patients). Mean age was 8.6. Clinical manifestations presented: increased body temperature, abdominal pain and abdominal tenderness during examination. Other clinical manifestations included: vomiting in 4 patients (66.66%), jaundice in 2 patients (33.33%). Lab results showed leucosytosis in 3 patients (50%), disorders of the liver in 2 patients (33%). 2 patients were diagnosed with spherocytosis and splenomegaly, 1 patient had empyema of gall bladder (wall thickness of the gall bladder > 3.7 mm). Clinical diagnosis was confirmed with ultrasound. Ultrasound criteria are: gall bladder thickness (3.5 mm), stones ose sludge with acoustic shadow, and collection of liquid around gall bladder (pericholecystitis). Results: All patients were initially treated with naso-gastric tube (suction), fluids and antibiotics. Cholecystectomy was performed in 4 patients and cholecys-tectomy with splenectomy in 2 patients due to spherocytosis. Discussion and conclusion: Choleli-thiasis in children is most commonly associated with haemolitic and haemoglobin diseases (Hereditary Spherocytosis, Sideropenic Anaemia, Thalasemia etc.). The incidence of cholesterol stones is higher than pigment stones. Cholecystitis and cholelithiasis in children are more common than previously thought. Ultrasound confirms with great accuracy the presence of stones and acalculous cholesytitis. Treatment is usually surgical, laparoscopic or open surgery, depending on the stage of the disease and the experience of the surgeon.

Retrocaval ureter, terms are anatomically descriptive but misleading in regard to development and results from altered vascular development. This anomaly is relatively uncommon, although it has clinical relevance. The ureter typically deviates medially behind the inferior vena cava, winding about and crossing in front of it from a medial to a lateral direction, to resume a normal course, distally, to the bladder. The renal pelvis and upper ureter typically appear elongated and dilated in a “J” or fishhook shape before passing behind the vena cava. Diagnoses were confirmed with intravenous urography and patient had an open surgical repair of the anomaly. The anomaly predominantly involves the right ureter, as was observed in these reported cases. Treatment is surgical allowing for correction of the anomaly with resolution of symptoms

Abstract: Introduction: Diffuse variant of GC is composed of gastric-type mucous cells, which generally do not form glands, but rather permit the mucosa and wall as scattered individual cells or small clusters in an “infiltrative” growth pattern. These cells appear to arise from the middle layer of the mucosa, and the presence of intestinal metaplasia is not a prerequisite. In this version, mucin formation expands the malignant cells and pushes the nucleus to the periphery, creating a “signet ring” conformation. If the signetring cells are more than 50% of the tumor, the tumor is classified as signetring cell carcinoma [1]. This case is important for reporting because we encountered for the first time such a carcinoma type, due to the new age and its atypical presentation. Case Presentation: We report a case of a 20 years Albanian old patient with Signet Ring Cell Type of Gastric CA. The patient was brought at the urgency with severe abdominal pain, nausea and peritoneal irritation. Clinical examination has been made in emergency, where we conclude the signs of peritoneal irritation, from native Ro no signs of pneumoperitoneum, while laboratory tests found a slight anemia (erythrocytes 3.36, HCT 25, HGB 8.6). Two hours later we repeated the native RTG and there were present the signs of pneumoperitoneum. It was indicated urgent surgical in-tervention. Intraoperatively, we found Ulcer duodenal perforation and undertook the operation procedures by Roscoe Graham technique. Conclusions: At this age, it is rare, and it is difficult to detect in its early stages, because the signs and symptoms are often non-existent, non-specific, or mimic as an ulcer. The most common symptoms are early heartburn indigestion, abdominal pain or discomfort, vomiting, constipation, diarrhea or to feel of filling after a small meal, loss of appetite, weakness and fatigue. Less common symptoms are anemia and weight loss.

Abstract: Solitary caecal diverticulum is an uncommon entity and therefore it is difficult to diagnose except during surgery exploration. It is extremely difficult to differentiate it preoperatively from acute appendicitis. We report a case of an enlarged colon segment, presenting macroscopically as tumor diverticulum in a 27-year-old female patient, presenting with a 2 day history of a severe abdominal right lower quadrant pain with accompanying anorexia, nausea, vomiting and high body temperature. After clinical assessment, laboratory examination, X-ray, and CT are performed, the indication for surgical treatment is set.

Abstract: Background: Tumor pathologies of the liver and bile ducts are relatively commonly diagnosed and the primary goal is to differentiate these lesions in the fastest possible time which determines the apropriate method of treatment. Aims and Objectives: Aim of this study is tracking and diagnostic imaging correlation of tumor pathologies of liver and bile ducts and determining the early diagnostic approach. Data obtained from this study are important for treatment procedures and succes of treatment. All cases with liver tumor pathologies from period 2012-2016 were examined with CT and MRI followed by other complementary imaging methods. Methods: CT examination was performed according to standard triple-phase protocol: non-enhanced phase, arterial phase and porto-venous phase, and in some cases with late phase after 5 minutes. In MRI examinations, standard protocol was performed: coronal T2 single-shot fast spin-echo (coronal T2 SSFs), Axial T2 respiratory-triggered fast spin-echo (axial T2-FRE)/or breath-hold fast-recovery fast spin-echo T2 body coil sizes XL, (axial T2-FRFSE-XL), Axial in-phase/out-of-phase, Axial/ coronal three-dimensional liver acquisition with volume acceleration (3D coronal pre lava). Results: For comparation, only patients with liver focal lesions were included in the study, and and patient were examined with both diagnostic imaging modalities (CT and MRI). 168 patients with liver tumor pathologies and biliary tree tumor pathologies are included in the study. Gender ratio was 85 males and 83 female (M/F ratio 1.03:1). Average age of patients was 58.41 years, (minimum age 1.5 years old and maximum 88 years of age). The most frequent age on diagnosis was 61 - 70 years (total of 49 patients or 29.16%). Benign tumors were found with 93 patients (55.35%) and malignant tumors in 79 patients (47.02%). Distribution in liver parenchyma was found in 113 patients (67.26%), while in 49 patients (29.17%) pathology was found in the biliary tract. The most affected liver segment was the fifth segment in 35 patients (20.83%), while the less affected segment was the second liver segment in 8 patients (4.73%). most of patients (62 patients or 36.90%) had more than two affected segments in time of diagnosis. Diagnostic criteria in this study require further future evaluation. Conclusion: Early diagnosis of are tumors remains a real challenge and has great impact in the survival rate of patients. Finally, our study showed that for our country’s institutions that there

Abstract: Background Glossina fuscipes fuscipes is the primary vector of trypanosomiasis in humans and livestock in Uganda. The Lake Victoria basin has been targeted for tsetse eradication using a rolling carpet initiative, from west to east, with four operational blocks (3 in Uganda and 1 in Kenya), under a Pan-African Tsetse and Trypanosomiasis Eradication Campaign (PATTEC). We screened tsetse flies from the three Ugandan PATTEC blocks for genetic diversity at 15 microsatellite loci from continental and offshore populations to provide empirical data to support this initiative. Methods We collected tsetse samples from 11 sites across the Lake Victoria basin in Uganda. We performed genetic analyses on 409 of the collected tsetse flies and added data collected for 278 individuals in a previous study. The flies were screened across 15 microsatellite loci and the resulting data were used to assess the temporal stability of populations, to analyze patterns of genetic exchange and structuring, to estimate dispersal rates and evaluate the sex bias in dispersal, as well as to estimate demographic parameters (NE and NC). Results We found that tsetse populations in this region were stable over 4-16 generations and belong to 4 genetic clusters. Two genetic clusters (1 and 2) corresponded approximately to PATTEC blocks 1 and 2, while the other two (3 and 4) fell within PATTEC block 3. Island populations grouped into the same genetic clusters as neighboring mainland sites, suggesting presence of gene flow between these sites. There was no evidence of the stretch of water separating islands from the mainland forming a significant barrier to dispersal. Dispersal rates ranged from 2.5 km per generation in cluster 1 to 14 km per generation in clusters 3 and 4. We found evidence of male-biased dispersal. Few breeders are successfully dispersing over large distances. Effective population size estimates were low (33–310 individuals), while census size estimates ranged from 1200 (cluster 1) to 4100 (clusters 3 and 4). We present here a novel technique that adapts an existing census size estimation method to sampling without replacement, the scheme used in sampling tsetse flies. Conclusion Our study suggests that different control strategies should be implemented for the three PATTEC blocks and that, given the high potential for re-invasion from island sites, mainland and offshore sites in each block should be targeted at the same time.
