[Evaluation of the diagnostic value of bedside ultrasonography in the emergency care]. / Az ágy melletti ultrahangvizsgálat diagnosztikus lehetoségeinek vizsgálata a sürgosségi betegellátásban.

INTRODUCTION: Rapid differential diagnosis of circulatory failure (shock) with unknown etiology is a daily challenge in the field of emergency medicine. The Rapid Ultrasound in Shock (RUSH) protocol is well known since 2010. With the use of targeted steps, the 4 forms of shock (cardiogen, distributive, obstructive, hypovolemic) can be separated in a few minutes. AIM: The aim of the authors was to evaluate the usefulness of the Rapid Ultrasound in Shock protocol for the diagnosis of different forms of shock. METHOD: The retrospective study included 123 critically ill patients admitted to the Emergency Department of Markusovszky Hospital, Szombathely, Hungary. Detailed records were obtained from all patients. RESULTS: From the 123 crirically ill patients, 64 patients suffered from circulatory failure, while the remaining patients had acute severe chest or abdominal pain, or respiratory failure. CONCLUSIONS: Based on the results of the first evaluation of the Rapid Ultrasound in Shock protocol in Hungarian patients, the authors conclude that, the bedside ultrasonography has a great value in emergency medicine, and this the protocol is suitable for its integration into patient care and education of emergency medicine.

Use of Diagnostic Imaging Modalities in Modern Screening, Diagnostics and Management of Breast Tumours 1st Central-Eastern European Professional Consensus Statement on Breast Cancer.

Breast radiologists and nuclear medicine specialists updated their previous recommendation/guidance at the 4th Hungarian Breast Cancer Consensus Conference in Kecskemét. A recommendation is hereby made that breast tumours should be screened, diagnosed and treated according to these guidelines. These professional guidelines include the latest technical developments and research findings, including the role of imaging methods in therapy and follow-up. It includes details on domestic development proposals and also addresses related areas (forensic medicine, media, regulations, reimbursement). The entire material has been agreed with the related medical disciplines.

Breast radiologists and nuclear medicine specialists have updated their previous recommendation/guidance at the 4th Hungarian Breast Cancer Consensus Conference. They suggest to adopt this actual protocol for the screening, diagnostics and treatment of breast tumors from now on. This recommendation includes the description of the newest technologies, the recent results of scientific research, as well as the role of imaging methods in the therapeutic processes and the followup. Suggestions for improvement of the current Hungarian practice and other related issues as forensic medicine, media connections, regulations, and reimbursement are also detailed. The guidance has been in agreement with the related medical disciplines.

Furosemide pharmacokinetics and pharmacodynamics following gastroretentive dosage form administration to healthy volunteers.

The objective of this study was to evaluate the pharmacokinetic and pharmacodynamic properties of furosemide following gastroretentive dosage from (GRDF) administration. A furosemide (60 mg) GRDF, releasing the drug during 6 hours in vitro, or an immediate-release tablet was administered to healthy male volunteers (N = 14) in a crossover design. Food and liquid intake were standardized; urine was collected, weighed, and assayed for furosemide and sodium concentrations. Pharmacokinetics of furosemide following the GRDF administration, as compared to the tablet, showed lower Cmax and indicated a prolonged absorption phase leading to longer mean residence time in the stomach. The sustained input of the drug significantly improved diuretic and natriuretic efficiencies during the first 5 hours and thereby increased the total effects measured over 24 hours. The unfolding controlled-release GRDF of furosemide improved the pharmacodynamic actions due to the sustained absorption in the stomach and jejunum, which delayed the body's counteractivity to the drug effect.

[Chronic recurrent multifocal osteomyelitis]. / Krónikus rekurrens multifokális osteomyelitis.

The chronic recurrent multifocal osteomyelitis has been reported very rarely in the literature. However, its significance must be emphasized, because it is a spontaneously healing, benign disease, as compared to the classical forms of osteomyelitis. It leaves behind almost no residual symptoms, and many operations, long antimicrobial therapy may be avoided by diagnosing it. In this case report the authors provide the review of the disease through the history of a 9-year-old boy.

Novel gastroretentive dosage forms: evaluation of gastroretentivity and its effect on levodopa absorption in humans.

PURPOSE: To design novel expandable gastroretentive dosage form (GRDFs) and evaluate their gastroretentive properties. Then, to assess the pharmacokinetics of levodopa compounded in such a GRDF in healthy volunteers. METHODS: Thin (<0.07 cm), large-dimensioned (> or = 5 x 2.1 cm), multi layer dosage forms (DFs) with different rigid polymeric matrices an mechanical properties were folded into gelatin capsules and wer administered to healthy volunteers with a light breakfast. GRDF unfolding and physical integrity were evaluated in vitro and in vivo (by gastroscopy and radiology). The pharmacokinetics of levodopa GRDF were compared to Sinemet CR in a crossover design. RESULTS: The combination of rigidity and large dimension of the GRDFs was a decisive parameter to ensure prolonged gastroretentivity (> or = 5 h). Large-dimension DFs lacking rigidity had similar gastroretentivity as a nondisintegrating tablet (10 mm). The GRDF rapidly unfolded and maintained their mechanical integrity. The absorption phase of levodopa was significantly prolonged following GRDF administration in comparison to Sinemet CR. CONCLUSIONS: The combination of size and rigidity of the novel GRDF enables a significant extension of the absorption phase of a narrow absorption window drug such as levodopa. This approach is an important step toward the implementation of such GRDFs in the clinical setting.
