The aim of the study is to define age and gender regularities of the linear morphometric parameters of the liver in children and adolescents on the basis of intravital imaging findings.Material and methods. The authors analyzed computed tomograms of the abdominal cavity in 75 children without visible pathology. All patients were divided into 4 groups depending on their age: early childhood, first childhood, second childhood, adolescence. The transverse, anteroposterior and vertical dimensions of the right and left hepatic lobes were investigated on 16-slice computed tomographs. The obtained findings were processed using variational statistical analysis, the mean value (M), standard error (m) and the statistical significance were defined using the Student's t-test.Results. There was a significant increase in the anteroposterior size of the right hepatic lobe in separate sections at different age periods. A statistical significance between the parameters of the anteroposterior size of the right hepatic lobe was registered in girls and boys within the following groups: on one section in the 2nd group of patients, on two sections in the 4th group of patients. A statistical significance between the parameters of the transverse size of the right hepatic lobe was registered on one section (ThXII) in the 2nd and 3rd groups, and on two (ThXI and LI) and three (ThXI, ThXII and LI) sections in the 3rd and 4th groups of girls and boys, respectively. A statistical significance between the parameters of the transverse size of the right hepatic lobe in girls and boys were recorded only in the 4th group on three sections (ThXI, ThXII and LI). The vertical size of the right hepatic lobe was significantly higher in the 2nd and 4th groups, and the differences in the parameters between girls and boys were noted only among adolescents. A significant increase in the anteroposterior size of the left hepatic lobe was registered only in girls of the 2nd and 3rd groups on two sections (ThXII and LI); a significant increase in the transverse size was only registered at the LI level in these groups of patients. A significant increase in the vertical size of the left hepatic lobe was only detected in girls of the first childhood compared with girls of the early childhood. No statistical significance was registered for any of the linear parameters of the left hepatic lobe between girls and boys of the same groups.Conclusion. Thus, there was a significant increase in the anteroposterior and transverse dimensions of the right hepatic lobe in separate sections and an increase in the vertical size between individual groups of the studied patients, as well as a statistical significance between girls and boys of the same group. A significant increase in the anteroposterior and transverse dimensions of the left hepatic lobe was detected only in girls of the 2nd and 3rd groups if compared with the girls of the 1st group. No significant differences were registered between girls and boys of the same groups for any of the linear parameters of the left hepatic lobe.

Vasculobiliary Injury

Abstract Vasculobiliary injuries (VBI) caused by cholecystectomies are infrequent but extremely serious. We report a case of a severe VBI successfully treated at our center. A 22-year-old woman underwent an open cholecystectomy as treatment for acute cholecystitis and bile duct stones. She was transferred to our center on postoperative Day 4 because of progressive jaundice and encephalopathy. After a proper investigation, we found an extreme VBI with infarction of the right hepatic lobe associated with complete interruption of the portal vein and proper hepatic artery flows and full section of the common hepatic duct. Right hepatectomy with portal—Rex shunt revascularization of the left hepatic lobe and Roux-en-Y hepaticojejunostomy to the left hepatic duct was done. The patient was discharged on the 60th postoperative day. Discussion: This case shows the successful surgical treatment of a severe cholecystectomy’s VBI, avoiding an emergency liver transplant.

The aim of the study is to establish ethno-territorial differences in the linear parameters of the proximal phalanges of the fingers in children and adolescents of the male sex of Tajikistan and Western India, regression equations that allow determining the nature of the dependence of the age of the examined and linear sizes of phalanges. On 366 radiographs of the right hand in children and adolescents aged 6-17 years from Tajikistan and India (Mumbai), the length of the proximal phalanges and the width of their diaphysis were measured. To determine the relationship between the age and the length, as well as the width of the diaphysis, Spearman's nonparametric correlation coefficient was used, because the age distribution does not correspond to normal. One-way ANOVA demonstrates the statistical significance of the increase in the length and width of the diaphysis of the proximal phalanges in boys and young men of Tajikistan and India with age, but the growth of these bones is uneven. For both Tajik and Indian boys, the closest correlation with age was found for the length of the second finger phalanx. It was found that in children in the smallest regions compared, the correlation was determined between their age and the length of the phalanx of the fifth finger. The length of the phalanx of the third finger increased most significantly with age in boys of the compared ethnic groups. The smallest height in length was determined for the phalanx of the fifth finger in boys in India and for the phalanx of the first finger in adolescents in Tajikistan. The maximum growth of the diaphysis in width was observed in the phalanx of the second finger, the smallest in the phalanges of the first and fifth fingers. The highest reliability was found with the length of the phalanx of the second finger. For Tajik boys, the parameters of the length of the phalanges of the III and IV fingers also have a correlation coefficient, therefore, they can be used to identify their age.

The aimof the study is to establish age and gender patterns of morphometric parameters of the gallbladder in children and adolescents based on the findings of intravital imaging.Material and methods.The authors analyzed computed tomograms of the abdominal cavity of 75 children having no visible pathologies of the abdominal organs. The participants were divided into 4 agegroups: early childhood,  first  childhood,  second  childhood,  adolescence.  The diagnostic  procedure was  performed  on 16-slice computed tomographs; a longitudinal size, a distance between the right and left walls, a distance between the anterior  and posterior  walls  and  a  volume  of  the  gallbladder  were  detected  in  the  study.  The data  obtained  were processed using variational and statistical methods,the mean value (M), standard error (m) and the significance of differences according to the Student's t-test were determined.Results.The longitudinal size of the gallbladder averaged 4.5±0.1 cm in the entire sample, 4.3±0.1 cm in girls, and 4.6±0.1 cm in boys; there was detected an increase from 3.7±0.2 cm in group 1 to 4.8±0.3 cm in group 4 (p=0.023). The transverse size of the gallbladder was 1.8 ± 0.1 cm, while in girls  -1.8 ± 0.1 cm, and in boys  - 1.7  ±  0.1  cm.  The  value  of  this  parameter  increased in  all  examined  children  from  1.3  ±  0.1  cm  in  group  1  to 2.1 ± 0.1 cm in group 4 (p = 0.001). In patients of all groups the average value of the distance between the anterior and  posterior  walls  of  the  gallbladder  was  2.8±0.1  cm.  In  girls  this  parameter  was  2.8±0.1  cm,  and  in  boys  -2.9±0.1  cm.  This  parameter  increased  in  all  patients  from  2.4±0.1  cm  in  group  1  to  3.4±0.1  cm  in  group  4 (p=0.001). The volume of the gallbladder constituted 13.6±0.8 cm3, in girls this parameter was 12.8±1.0 cm3, and in  boys  - 14.2±1.3  cm3.  The  volume  of  the  gallbladder  increased  in  all  patients  from  7.3±1.1  cm3  in  group  1  to 19.4±1.9 cm 3 in group 4 (p=0.001).Conclusion.The most significant increase in most studied parameters (p≤0.05) was noted in children of the first childhood group compared with children of the early childhood group, and in adolescents co mpared with children  from  the  second  childhood  group  without  differentiation  by  gender. A  significant  increase  in  the  morphometric parameters of the gallbladder was determined mainly in boys of the first childhood group compared with  children  of  the  early  childhood  group  and  in  adolescents  compared with  children  of  the  second  childhood group. In girls there was observed a tendency to a smooth increase in parameters from group to group; a significant increase was determined by the parameter “the distance between the anterior and posterior walls” in children of the second age group compared with children of the first age group (p=0.022). Most of the gallbladder morphometric parameters did not significantly differentiate in girls and boys of the same age group.

Background and Aims: The importance of sessile serrated lesions (SSLs) in the pathogenesis of colorectal carcinoma has been recently established. These are supposed to cause the so-called “interval cancer”, having a rapidly progressive growth and being difficult to detect and to obtain an endoscopic complete resection. We aimed to establish the most important metabolic risk factors for sessile serrated lesions. Methods: We performed a retrospective case-control study, on a series of 2918 consecutive patients who underwent colonoscopy in Gastroenterology and Endoscopy Unit, County Clinical Emergency Hospital, Târgu-Mureș, Romania between 1 st of January 2015-31 th of December 2017. In order to evaluate the metabolic risk factors for polyps’ development, enrolled participants were stratified in two groups, a study group, 33 patients with SSLs lesions, and a control group, 138 patients with adenomatous polyps, selected by systematic sampling for age and anatomical site. Independent variables investigated were: gender, smoking, alcohol consumption, obesity, arterial hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, hyperuricemia, nonalcoholic liver disease. Results: For SSLs the most common encountered localization was the right colon in 30.55% of cases. By comparative bivariate analysis between SSLs group and control group, it was observed that hypertension (p=0.03, OR 2.33, 95 %CI 1.03-5.24), obesity (p=0.03, OR 2.61, 95 %CI 1.08-6.30), hyperuricemia (p=0.04, OR 2.72, 95 %CI 1.28-7.55), high cholesterol (p=0.002, OR 3.42; 95 %CI 1.48-7.87), and high triglycerides level (p=0.0006, OR 5.75; 95 %CI 1.92-17.2) were statistically associated with SSLs development. By multivariate analysis hypertension and hypertriglyceridemia retained statistical significance. Conclusions: Our study showed that the highest prevalence of SSLs was in the right colon and hypertension and increased triglycerides levels were associated with the risk of SSLs development. These risk factors are easy to detect in clinical practice and may help identifying groups with high risk for colorectal cancer, where screening is recommended.

BACKGROUND Radiology now plays a major role to diagnose, monitoring, and management of several diseases; numerous diagnostic and interventional radiology procedures involve exposure to ionizing radiation. Radiology now plays a major role to diagnose, monitoring, and management of several diseases; numerous diagnostic and interventional radiology procedures involve exposure to ionizing radiation. OBJECTIVE This study aimed to discover and compare the awareness level of radiation doses, protection issues, and risks among radiology staff in Jeddah hospitals. METHODS A cross-sectional survey containing 25 questions on personal information and various aspects of radiation exposure doses and risks was designed using an online survey tool and the link was emailed to all radiology staff in eight tertiary hospitals in Jeddah. The authors were excluded from the study. A P-value of < .05 was used to identify statistical significance. All analyses were performed using SPSS, version 21. RESULTS Out of 156 participants the majority 151 (96.8%) had poor knowledge score, where the mean scores were 2.4±1.3 for doses knowledge, 2.1±1.1for cancer risks knowledge, 2.3±0.6 for general information, and 6.7±1.9 for the total score. Only 34.6% of the participants were aware of the dosage of a single-view chest x-ray, and 9.0% chose the right answer for the approximate effective dose received by a patient in a two-view. 42.9% were able to know the correct dose of CT abdomen single phase. There is a significant underestimation of cancer risk of CT studies especially for CT abdomen where only 23.7% knew the right risk. A p-value of <0.05 was used to identify statistical significance. No significant difference of knowledge score was detected regarding gender (P =.2) or work position (P=.66). CONCLUSIONS Our survey results show considerable inadequate knowledge in all groups without exception. We recommended a conscientious effort to deliver more solid education and obtain more knowledge in these matters and providing periodic training courses to teach how to minimize the dose of radiation and to avoid risk related.
