Hungarian Radiology - 2009;83(03)

[INTRODUCTION - Omental infarction is a rare entity, mimicking symptoms of acute appendicitis. Although omental infarction has typical morphology, both on sonography and CT, it is rarely diagnosed preoperatively. CASE REPORT - A 4-years-old girl presenting with right lower quadrant abdominal pain underwent abdominal sonography, which revealed normal appendix and a superficial hyperechoic solid mass at the site of the pain. The patient underwent laparotomy which confirmed the presumed diagnosis of partial omental necrosis. The necrotic tissue was resected, the appendix was normal. After uneventful postoperative course the child became symptom -free and was discharged. CONCLUSION - The sonomorphology of omental infarction is typical. The suspicion of this entity should be considered as a differential diagnosis of appendicitis, especially if normal appendix can be visualized.]

[Colorectal cancer screening: Lessons from the American experience]

BAFFY György, TÁRNOKI Dávid László, TÁRNOKI Ádám Domonkos, BAFFY Noémi

[Colorectal cancer is one of the most common malignancies of our times. The disease takes many years to develop and is typically preceded by polyp formation, which allows timely screening and diagnosis. A number of tests and procedures have been developed to screen for colorectal cancer and its premalignant conditions. However, apparent heterogeneity of the disease, redundancy of the available screening modalities, as well as costs and potential pitfalls of these preventive measures require careful strategic planning. In the United States, recent advances in the campaign for colorectal cancer screening provide important lessons that may guide similar initiatives in Hungary.]

[Portal embolisation prior to liver resection]

MÓZES Péter, MÉSZÁROS György, TÓTH Judit, SÁPY Péter

[INTRODUCTION - By partial embolisation of the vena portae the number of the patients suitable for radical liverresection can be enhanced, the safety of the operation can be increased, the subsequent results improved. The method is based on the experience that when blocking the circulation of the portal system in special segments of the liver, the other part of the organ tries to substitute the functional deficiency by hypertrophy. Vena portae embolisation is justified in cases when the liver substance remaining after the planned operation is critically small. PATIENTS AND METHODS - The authors carried out vena portae embolisation at Debrecen University Medical and Health Science Centre since October 2003 on six patients. Assessments were made studying the volume of the whole liver, the lobe affected by embolisation and that of the unaffected lobe, by CT-volumetry. The average age of the patients (four men and two women) was 63 years (51-67 years). The hepatic tumour was an extended metastasis localised to one lobe in five cases, and HCC in one of the patients. In each case we carried out closing the right lobe’s portal system. RESULTS - In five cases the left lobe showed increase following the portal embolisation of the right lobe intended to be removed. On the average four-six weeks passed between the two CT-examinations. The growth of the left lobe was an average of 42% (min. 11.8%, max. 75.6%). CONCLUSION - In selected patients the embolisation of the vena portae system of the tumorous liver-segments is a suitable method for enlargening the size of the liver substance remaining after an extensive resection.]

[Hematopoetic stem cell transplantation for pediatric non-hematological solid tumors]

HAUSER Péter, KRIVÁN Gergely

[High-dose chemotherapy followed by stem cell rescue or allogeneic stem cell transplantation in the treatment of solid tumor with non-hematologic origin applied for more than three decades. High-dose chemotherapy with stem cell rescue is the part of standard fi rst line therapy for several chemosensitive tumors with unfavorable outcome (neuroblastoma, Ewing-sarcoma, medulloblastoma), and also successfully applied in certain therapy-resistant or recurrent solid tumors (germ cell tumors, Wilmstumor). Allogeneic transplantation with reduced intensity conditioning is still not successful in terms of survival in pediatric solid tumors with non-hematological origin. In present paper results of autologus and allogeneic stem cell transplantation in different pediatric solid tumor are discussed.]

[Abdominal and thoracal manifestations of posttransplantation lymphoproliferative disorder in children]

VÁRKONYI Ildikó, NYITRAI Anna, MAGYAROSY Edina, RÉNYI Imre, SZEBERÉNYI Júlia, KIS Éva

[INTRODUCTION - Posttransplantation lymphoproliferative disorder is a secondary disease of transplanted patients, usually with good response to reduction of immunsuppressive therapy. PATIENTS AND METHODS - The lymphoproliferative disorder was diagnosed in four children among 139, renal, liver and lung transplanted patients. Clinical data (original disease, transplanted organ, age and time elapsed since transplantation at the diagnosis of the disorder) and imaging findings (chest X-ray, thoracal and abdominal computed tomography scans) were analysed retrospectively. RESULTS - Thoracal and abdominal forms were the most frequent manifestations of posttransplantation lymphoproliferative disorder in our patients. Following features have been diagnosed on imaging studies: multiple liver nodules (two cases), multiple nodules in the renal parenchyma (two cases), splenomegaly (two cases), bowel wall thickening (two cases). Retroperitoneal and mesenteric lymph node enlargement was found in all patients. Thoracal manifestations were as follows: mediastinal lymphadenopathy (two cases), hilar mass (one case), multiple pulmonary nodules (one case). Renal rupture with perirenal hematoma in one case, hilar mass envolving the main bronchus in one case, hepatic abscesses necessitating drainage in one case, and bowel wall necrosis in one case were the complications of posttransplantation lymphoproliferative disorder. CONCLUSION - Presenting symptoms are aspecific, often mimicking infection. Posttransplantation lymphoproliferative disorder has to be excluded if aspecific symptoms in a transplanted patient are present, or the patient does not react properly on antibiotics. First step investigations include chest X-ray and abdominal sonography. Neck, chest and abdominal CT are mandatory for detecting all manifestations, for staging the disease and to determine the best localization of obligatory biopsy.]

[Endo-sonographic anatomy of the ventricular system]

REISCH Róbert, RESCH Klaus, PERNECZKY Axel

[A preclinical cadaver study was performed to test a transendoscopic sonographic probe for neurosurgery. In 25 fresh post-mortem adult human cadaver with a total of 39 endo-sonographic dissections in the ventricular system were carried out. A sonograph with an outer diameter of 6 F was used and radial sonograms were made by a realtime image technique. First results showed precise imaging, comparable to a CT in a neighbouring area of 3 cm. In this publication, the authors describe the endo-neurosonographic anatomy of the ventricular system. The sonographic probe was advanced through the working canal of a ventriculoscope, then the endoscopic and sonographic imaging were compared. Results were documented by paralell sonographic and endoscopic photo and video recordings. Based on the authors experience, it is revealed that the additional sonographic view could also be used as a navigation tool.]

[Application of „The Parental Belief Scale for Parents of Hospitalized Children” questionnaire in Hungarian language]

MIKLÓSI Mónika, PERCZEL FORINTOS Dóra

[Aim of the study: Beliefs about parental role and efficacy was shown to be important in adaptation to child’s hospitalization; there is a lack of adequate measure of this construct, however. Our aim was the evaluation of the Hungarian version of The Parental Belief Scale for Parents of Hospitalized Children (PBS; Melnyk, 1994) assessing parents’ beliefs about their ability to understand and predict their children’s behaviours and emotions, as well as to participate in their children’s care during hospitalization. Sample and methods: The Hungarian version of the PBS was evaluated using a back-translation process. One hundred parents of hospitalized children in Heim Pál Children’s Hospital, Department of Surgery and Traumatology fulfilled the measure along with questionnaires regarding demographics, general parental self-efficacy and state-anxiety. Results: The Hungarian version of the PBS showed excellent internal consistency (α=0,94), and good stability (r=0,85 p<0,001). A significant positive correlation of medium effect size was found between PBS scores and general parental self-efficacy (r=0,30 p=0,025). Parent’s state anxiety was significantly negatively related to their self-efficacy beliefs regarding hospital setting (r=-0,48 p<0,001). Conclusion: The Hungarian version of the PBS was shown to be a reliable and valid instrument for measuring efficacy-beliefs of parents of hospitalized children.]

KÓRÁSZ Krisztián

[The paper gives introspection into the child sexual abuse risk assessment practice in the USA by reviewing the literature. According to the definition of the World Health Organization, sexual assault is considered to be any act involving a child in a sexual activity if he or she can not be considered as prepared for the child's age or development. The author also makes an attempt to present some issues and pos­sible solutions regarding the current practice. ]
