Different presentations of renal cell cancer on ultrasound and computerized tomography.

Renal cell carcinoma (RCC) is the most common malignant tumor of the kidney. The major goal of imaging techniques is to correctly differentiate between benign and malignant renal lesions. We present the cases of six patients with renal masses that were interpreted completely differently based on ultrasound (US) and computerized tomography (CT) findings.From January 1st, 2008 to March 1st, 2014, 307 patients from our center underwent nephrectomy for RCC. In all patients US and CT were performed before the operation.In six patients, the US indicated a focal, solid renal lesion that was interpreted by CT as a cystic lesion (Bosniak II-III). Because discrepancies were evident, renal biopsies were performed. The biopsies revealed RCC in the six patients, all of whom underwent subsequent nephrectomy. All of the patients were confirmed to have macroscopically solid RCC without any cystic components.In most cases, CT is the most accurate diagnostic technique for the clinical diagnostic classification of renal masses. In cases where US characterizes a renal lesion as solid, despite CT findings of a cystic lesion, kidney biopsies are recommended. The 6 cases reported here support our belief that, in diagnostic processes of RCC, these techniques should be complementary used.

The relationships between self-esteem, emotional reactions and quality of life in pediatric locomotory trauma patients.

The main aim of this study was to establish the relationships between several psychosocial characteristics in children and adolescents differently treated for isolated long tubular bones' fractures. Examined variables were: self-esteem, basic emotional reactions toward illness or injury including depression and anxiety, as well as perception of quality of life and social support during the treatment. Whole sample comprehends 135 patients, both gender, 10-18 years of age, treated for mentioned fractures in period 2003-2005 at the Departments of Pediatric Surgery of 3 hospitals: University Hospital Centre in Rijeka and Clinical Children's Hospital in Zagreb, both in Croatia and University Hospital in Mostar, BiH. 73 patients were treated conservatively (CT), 40 of them underwent Elastic Stable Intramedullary Nailing (ESIN) and 22 of them underwent other surgical techniques (OST). Basic methods of work were: interview to collect data for half-structured socio-demographical questionnaire, evaluation of medical records and self-reported questionnaires including: Rosenberg Self-esteem Scale (RSS), Children Depression Inventory (CDI), Spielberg State Trait Anxiety Inventory (STAI), Short Form 36 Health Survey (SF-36) and Test of Perception of Social Support (TPSS). RSS, CDI and STAI were administered to the patients at baseline and after 6 months of the trauma, while SF-36 and TPSS after 1 month of the trauma. Results of this study point to close and strong relationships between examined variables, mostly statistically significant at level p < 0.01 in all patients with fractures, regardless of the type of the treatment. There were also statistically significant differences in all variables between first and second measure; self-esteem increased and depression and anxiety decreased during the time in all patients (with different dynamics regarding the type of treatment); higher perception of social support enhanced that effect. Perception of quality of life in whole sample in summary measures was statistically significant at level p < 0.01 correlated positively with self-esteem and negatively with depression and anxiety, thus connection with perception of social support was statistically significant only in sibdomain of physical pain. There was also statistically significant difference in self-perception of quality of life related to psychosocial variables according to the type of treatment (F = 3.27; p = 0.01). Results of this study suggest that there are strong connections between physical trauma and different psychosocial variables in patients which point at need of understanding locomotory trauma in children in wider context including physical state and social functioning of the patient as well as the choice of type of treatment of fractures which influences complete process of healing.
