Background and Objectives: The aim of the study was to determine the association between presences of fatty pancreas (FP) with the features of metabolic syndrome (MeS) in patients with non–alcoholic fatty liver disease (NAFLD) and to establish a new noninvasive scoring system for the prediction of FP in patients with NAFLD. Material and Methods: 143 patients with NAFLD were classified according to FP severity grade into the two groups and evaluated for diagnostic criteria of MeS. All patients underwent sonographic examination with adiposity measurements and the liver biopsy. Liver fibrosis was evaluated semi-quantitatively according to the METAVIR scoring system and using non-invasive markers of hepatic fibrosis. Results: Waist circumference (WC) was predictive for increased risk of FP in NAFLD patients. Elevated fasting plasma glucose, total cholesterol, serum amylase and lipase levels were associated with presence of severe FP (p value = 0.052, p value = 0.007, p value = 0.014; p value = 0.024, respectively). Presence of increased amounts of mesenteric fat was associated with severe FP (p value = 0.013). The results of this study demonstrated highly significant association between NAFLD and presence of FP. The model for predicting the presence of FP was designed with probability value above 6.5. Conclusion: Pancreatic fat accumulation leads to worsening of pancreatic function which in turns exacerbates severity of metabolic syndrome associated with both, NAFLD and NAFPD.

Introduction Spontaneous cholecystoduodenal fistula is a rare complication of the gallbladder calculosis. Bowel obstruction is the complication in less than 1% of these patients. The pathognomonic triad (Rigler triad) of pneumobilia, small-bowel distention, and ectopic gallstones is typical for gallstone ileus. In only 1-3% of the patients with bowel obstruction by ectopic gallstone the localization of obstruction is in the duodenum, and it is called Bouveret syndrome. The rarest complication is a floating non-obstructing gallstone trapped in the stomach. Outline of cases We present three elderly female patients with persistent abdominal pain and known gallbladder calculosis in the patients' histories. Plain radiography of the thorax and abdomen and ultrasound were performed as the first choice and contrast-enhanced computer tomography (CT) was done subsequently. In the first patient, CT and magnetic resonance imaging (MRI) showed signs of pneumobilia, cholecystoduodenal fistula, and the presence of the gallstone in the stomach. The iodine contrast X-ray swallow test revealed a cholecysto-duodenal bulb fistula and floating calculus in the stomach, confirmed by endoscopy. In the second patient with persistent abdominal pain, CT and barium swallow test showed signs of pneumobilia, cholecystoduodenal fistula, and two ectopic gallstones obstructing duodenum-Bouveret syndrome. The third case showed signs of the Rigler triad-typical signs of gallstone ileus. Conclusion Spontaneous cholecystoduodenal fistula is a rare condition with possible complications such as Bouveret syndrome, gallstone ileus and floating, non-obstructive gallstones in the stomach, as the rarest possible complication. CT, MRI with magnetic resonance cholangiopancreatography, as well as the contrast X-ray swallow test can be very helpful in the detection of the bilio-enteric fistula and ectopic gallstones.

Antiphospholipid syndrome (APS) is an autoimmune disease which is characterized by arterial and venous thromboses, fetal loss, and the presence of antiphospholipid antibodies in the serum. It is characterized by accelerated atherosclerosis. Increased tendency towards thrombosis leads to the occurrence of various vascular events. The objective of our study was to determine if there are subclinical changes on lower limb arteries in APS patients and what the best diagnostic choice for their establishment is. In this study, we analyzed 50 patients with primary antiphospholipid syndrome (PAPS) and 50 patients, who have secondary antiphospholipid syndrome (SAPS). The results were compared to 50 controls. The groups were comparable with respect to age, gender, and traditional risk factors except for the lipid status, since controls had significantly higher levels of cholesterol and triglycerides. Study was conducted on 64-multi-slice computed tomography (64-MSCT), where we analyzed quantitative and morphological characteristics of blood vessel-detected lesions. Patients from the control group had statistically very significant elevated cholesterol and triglyceride levels in regard to the patients with SAPS and PAPS (p < 0.001 and p < 0.05). Analyzing percentage of diameter stenosis, we have established that lesions from group with 0-30% diameter stenosis (DS) in patients with PAPS (n = 47) and SAPS (n = 39) are more common than that in control group (n = 3, p < 0.001). The incidence of lesions higher than 70% DS in control group (n = 74) was statistically significant than that in patients with SAPS (n = 74, p < 0.05), while very statistically significant than that in patients with PAPS (n = 48, p < 0.001). Analyzing the qualitative characteristics of plaques, we have established significant higher frequency of soft tissue (n = 32) and mixed lesions (n = 36) in patients with PAPS than the calcified one (n = 7, p < 0.001). Our study showed that the subclinical manifestation of changes on lower extremity arteries is more common in patients with APS. Because of its safety and accuracy, the method of choice is 64-MSCT angiography in monitoring disease progression.

Objective: The potential contribution of asymmetric dimethylarginine (ADMA) and high-sensitivity C reactive protein (hsCRP) to endothelial dysfunction in APS patients has not been studied in detail, until now. The study involved 105 APS patients (59 diagnosed with primary APS (PAPS) and 46 APS associated with systemic lupus erythematosus (SAPS)) who were compared to 40 controls. Endothelial dysfunction was assessed by measurement of flow-mediated dilatation (FMD) and glyceryl trinitrate dilatation (NMD) of the brachial artery. ADMA (micromol/L) was analyzed by ELISA. Results: FMD in patients with APS was significantly lower than that of the controls (p < 0.001), with no difference between the PAPS and the SAPS groups. ADMA and hsCRP concentrations were significantly higher in the patient cohort than in the control group (p < 0.001, p = 0.006, respectively), as was the case with the SAPS group as compared to the PAPS group (p < 0.001, p = 0.022, respectively). FMD impairment correlated to ADMA (ρ 0.472, p < 0.001) and to hsCRP (ρ 0.181, p = 0.033). In the regression model, the ADMA concentration confirmed the strength of its association (B 0.518, SE 0.183, Wald 8.041, p = 0.005, Exp(B) 1.679, 95% CI 1.174–2.402) to FMD impairment. The synergistic probability model of ADMA and hsCRP caused FMD impairment when the positivity of β2GPIIgG was added. ADMA may be used as a simple and low-cost tool for verifying the presence of endothelial dysfunction in APS patients. According to the results of the study, we could presume that hsCRP, together with aPL, has a preparatory effect on the endothelium in causing endothelial dysfunction.

Antiphospholipid syndrome (APS) is an autoimmune disease defined by accelerated atherosclerosis, arterial and venous thrombosis, fetal loss, and the presence of antiphospholipid antibodies (aPL) in the serum and which leads to the occurrence of various vascular events. Nonspecific abdominal pain can be one of the symptoms due to changes on visceral blood vessels. The goal of our work is to show the results we obtained in multidetector computed tomography (MDCT) angiography examination of visceral arteries, comparing patients with primary antiphospholipid syndrome (PAPS) and secondary antiphospholipid syndrome (SAPS) with control group. In this study, we analyzed 50 patients with primary PAPS and 50 patients, with secondary SAPS. The results were compared to 50 patients in the control group. The groups were compared in terms of age, gender, and the most common risk factors except for the lipid status, since controls had significantly higher levels of cholesterol and triglycerides. The study was conducted on 64-MDCT, on which we analyzed quantitative and morphological characteristics of the blood vessel lesions. Patients from the control group had statistically significant elevation of cholesterol and triglyceride levels compared to the patients with SAPS and PAPS (p < 0.001 and p < 0.05). The results showed that the frequency of changes is statistically (p < 0.05 and p < 0.001) more common in patients with PAPS and SAPS than in the control group. Statistically significant difference between the groups was found in superior and inferior mesentery arteries. Analyzing the number of lesions, there was statistically high difference between the patients with one and two lesions than in patients with four or more lesions (p < 0.001), lower difference compared to the patients with three lesions (p < 0.01), while there was low, but yet statistically important difference between the patients with three lesions and those with five or more blood vessel lesions (p < 0.05). Analyzing percentage of diameter stenosis, we established that the lesions in the groups of 0-30% diameter stenosis (DS) and 30-50% DS in patients with PAPS (n = 42) and SAPS (n = 44) are more common than in the control group (n = 18, p < 0.05). Analyzing the qualitative characteristics of plaques, we established significantly higher frequency of soft tissue and mixed lesions than calcified ones in patients with PAPS and SAPS (p < 0.001; p < 0.05). Our study showed that the subclinical manifestation of the changes on visceral arteries is more common in patients with APS. Patients with abdominal pain were those with two or more lesions, and according to our results, majority had PAPS. Because of its safety and accuracy, the method of choice is MDCT angiography in monitoring the progression of disease.

Background/Aim: Segmental fractures represent complex tibial injuries, featuring a unique fracture type that is most commonly caused by a high-energy trauma. These fractures are considered to be a treatment challenge for orthopaedic surgeons due to their sporadic presentation, wide zone of soft tissue injury, and increased rate of complications. They are characterised by highly unstable intermediary segment and high rate of open fractures. The method of Ilizarov with its characteristics could offer many advantages over the existing operative techniques. This method, using a percutaneous approach, minimizes the intraoperative trauma and avoids the additional compromising of the biological environment at the fracture site. The aim of this study is to evaluate the results of Ilizarov fixator in treatment of segmental tibial fractures. Methods: We analysed 30 patients treated with an Ilizarov fixator between 2012 and 2017. Average age was 36 years (from 24 to 65). The most common mechanism of injury was a road traffic accident. Open fractures were noted in 22 cases. All fractures were reduced using indirect percutaneous techniques with a great focus on achieving the correct length, rotation and axial alignment of fragments. All patients were advised to bear weight as tolerated from the second postoperative day. Bone healing and functional results were evaluated according to criteria established by the Association for the Study and Application of the Method of Ilizarov. Results: Bone healing was achieved in all patients. The average time to union was 25 weeks (19 to 36 weeks). The bone results were excellent in 23 patients, good in five patients and fair in two patients. The functional results were excellent in 22 cases, good in 5 and fair in three cases. Eight patients had minor pin-tract infections, successfully treated with oral antibiotics. Patients were without any major complications. Conclusion: Ilizarov method is a safe and efficient treatment modality for segmental tibial fractures.
