[Radiology of pancreas: review from the last year - Gastro Update 2007]

FORRAI Gábor

[PURPOSE - To demonstrate the recent results in radiological diagnostics of pancreas, and the actual place of the imaging and interventional methods. METHOD - Systematic review of the most recent articles from the last year in the following subjects: acute, chronic and autoimmune pancreatitis, pancreatic cancer and other tumors, PET and special imaging problems in pancreas transplantation. RESULTS - Annually, experience in pancreatic diagnostical methods are accumulating rapidly. Therefore, there is a continuous change in the examination algorithm with new diagnostic and therapeutic modalities making their way into the daily routine. Some of the algorithms become obsolete within a few years and their further application is considered mismanagement. Some other methods become obligatory steps in the diagnostics. These are the reasons why up-to-date knowledge of the literature is mandatory.]

[Role of contrast enhanced ultrasound in clinical practice]

HARKÁNYI Zoltán

[Ultrasound contrast agents consist of micro bubbles which can be visualized during their short intravascular and parenchymal transit time. An US system with special software, a small amount of intravenous contrast agent and a skilled operator is necessary to produce a successful study. This method can also be introduced into the clinical practice in our country. Careful indications and well performed studies can reduce the number of unnecessary CT and MR studies and biopsies. Contrast enhanced US has special clinical significance in the detection and characterization of focal liver masses, monitoring drug and local treatment effects of different abdominal tumors and in the case of injury of abdominal parenchymal organs.]

[Evaluation of cystic renal masses with MDCT]

BATA Pál, MIKUSI Regina, KARLINGER Kinga, BÉRCZI Viktor, SZENDRŐI Attila, ROMICS Imre

[Modern CT and MRI scanners can give an exact and rapid diagnosis in the case of most cystic renal masses. Dilemma in their diagnosis is whether or not the changes need surgical intervention. The question of follow-up is decided with the use of the Bosniak classification. To characterize the cystic changes excellent quality, multiphasic MDCT examination is necessary with the following parameters: 80-120 mls. of non-ionic iodinated intravenous contrast material given with an injector at 3 ml/sec flow-rate with saline flush technique, unenhanced and post-contrast scans obtained at 35 and 70 seconds, with more scans at 120-300 seconds, as deemed necessary. A collimation of 16x1.5 mm with an overlap of 50% should be aimed for. Through the primary data we perform a reconstruction of 2 mm, with an option to create volume-rendered image sin the post-processing phase, as necessary. With the help of this CT protocol we can measure the different criterions of Bosniak classification in the cystic masses like minimal, smooth or irregular wall thickening, with or without enhancement. We can recognize hairline thin or thickened septa, fine or irregular (thick or nodular) calcifications, solid component with or without contrast enhancement. Using these criteria each cystic mass can be assigned to a Bosniak cystic category (I, II, IIF, III and IV)]

[High resolution sonography for the examination of peripheral nerves]

JOSEF Böhm

[High-frequency sonography is an important method for the imaging of the peripheral nerves, even though it is rarely used. For the examination of superficially located nerves, currently available transducers with frequencies between 12-17 MHz offer a better axial resolution than even MRI. Sonography is superior to MRI especially for the examination of nerves of the upper extremity. Main indications for the sonography of the nerves are entrapment syndromes, traumatic injuries of the nerves, tumors, polyneuropathies and sonographically-guided interventions. The sensitivity of sonography and electrophysiology in the diagnosis of carpal tunnel syndrome and cubital tunnel syndrome are comparable. The combination of ultrasonography with electrophysiological studies increases the diagnostic yield in carpal and cubital tunnel syndromes. Sonography provides information for planning of peripheral nerve surgery and is helpful in evaluating postoperative complications. In selected cases, sonography can detect nerve lesions that require operative therapy earlier than electrophysiology. With technical enhancements, highfrequency ultrasonography is gaining increasing importance in the routine diagnostics of peripheral nerves lesions.]

FORRAI Judit

[There is a long history of women in dentistry. Dr. Gizella Barát was the first female dentist in Hungary. She was among the first women admitted to the University in Hungary. Dr. Gizella Barát was a typical example of an emancipated, modern, wo­man, devoted to medical profession in the early 20th century. After graduation she was employed in the Polyclinic and started there her carreer at professor Armin Rott­mann. We follow her life’s story with existing however incomplete biographyc data.]

[Pneumococcal meningitis in children - 9 1/2-year-experience at Szent László hospital, Budapest, Hungary ]

IVÁDY Balázs, LIPTAI Zoltán, ÚJHELYI Enikő, BALÁZS György

[Background and objective - No recent publications are available about pneumococcal meningitis in Hungarian children. The aim of this study was to collect data of epidemiological, clinical and prognostic features of pneumococcal meningitis in children treated at Szent László Hospital, Budapest, Hungary. Methods - We conducted a retrospective review of medical charts and follow-up records of patients aged 1 to 18 years admitted to our Pediatric and Pediatric Intensive Care Units due to pneumococcal meningitis between 1st Jan 1998 and 30th Jun 2007. Results - 31 children with 34 cases of pneumococcal meningitis were admitted to our hospital in the study period. Two children developed recurrent illness. The mean age was 6 years, 26% were under 1 year of age. The mean duration of hospital stay was 21 days, 97% required intensive care. Frequent clinical symptoms were fever (100%), nuchal rigidity and vomiting (78%), altered mental status (71%), Kernig's and Brudzinski's signs (58%) and seizures (41%). Otitis media, sinusitis, mastoiditis were present in 44%, 58%, 41%, respectively. Subdural effusion, parenchymal cerebral lesion and sinus thrombosis were documented in 5, 3 and 2 cases, respectively. One third of the patients recieved ceftriaxon, two thirds were administered ceftriaxon and vancomycin. Adjunctive therapy with dexamethason was given to 91% of the children. 70% of patients required mechanical ventillation. 9 patients (25%) required endoscopic sinus surgery. In 13 cases (38%) mastoidectomy, in 5 children (15%) neurosurgery was performed. The case fatality rate was 23.5%. 8 (23.5%) patients had mild or moderate, 1 child (3%) developed severe neurological sequelae. Conclusion - Pneumococcal meningitis in children remains a source of substantial morbidity and mortality in childhood. The long hospital stay, the frequent need for intensive care and severe neurologic sequelae emphasize the importance of early diagnosis, early treatment and prevention with pneumococcal conjugate vaccines.]
