[Sudden cardiac death (part 2)].

In addition to acute treatment of sudden cardiac death the authors focus attention in particular on an analysis of long-term diagnostic and therapeutic provisions to cope with this serious clinical condition. The basic therapeutic procedures include influencing of the arrythmogenic substrate and modulating factors associated with the development of tachyarrhythmias by revascularization of the myocardium and radiofrequency ablation; as to drugs in particular by administration of angiotensin converting enzyme inhibitors and in rare instances by the application of other surgical methods. Haemodynamically important ventricular arrhythmias are treated by antiarrhythmics (beta-blockers, amiodarone, sotalol) and an implantable cardioverter-defibrillator. In the conclusion the authors propose a diagnostic therapeutic algorithm after circulatory arrest with successful cardiopulmonary resuscitation.

Interesting clinical case studies involving secondary causes of hypertension.

While essential hypertension is very prevalent, secondary hypertension does occur in clinical practice with sufficient frequency to warrant special attention being given to those patients with severe hypertension who do not respond to standard treatments. The evaluation, diagnosis and treatment of secondary hypertension pose interesting challenges to the physician. In this article, three patients are described with different secondary causes of hypertension.

[Coronet status of digital radiography in chest medicine].

It has been ten years since Computed Radiography (CR) was introduced to evaluate its efficacy on the diagnosis of chest diseases in Japan. Over 600 CR systems are in their daily clinical use. CR images improve the quality of chest X-ray diagnosis with its enhancement parameters, that is, the digital image's contrast and edge enhancement. In daily clinical work, however, some abnormalities on the images, such as infiltrative shadows and fine miliary shadows, have shown CR imaging to have no superiority in visualization compared to conventional X-ray films. The quality of CR images greatly depends on the reconstruction algorithm. The diagnostic system of CR images using CRT monitor and workstations will be warranted in order to make the CR system the optimal and most useful modality in chest medicine. The CR system is potentially applicable in Picture Archiving and Communication System (PACS).

[When should surgery be performed in traumatic hemoperitoneum ].

Authors in their theoretical report discuss problems of traumatic haemoperitoneum resulting from blunt abdominal injury including diagnostics and therapy. They put the stress on diagnostic-therapeutic algorithm. It is emphasized the necessity of immediate US of the abdomen and at the haemodynamically stable patients helical CT scan. Classification of injured certain abdominal cavity organs is mention and suggested unification of these classifications. It is highlighted conservative treatment of traumatic haemoperitoneum with regular monitoring including monitoring of intralpha abdominal pressure and abdominal compartment syndrome. Damage Control Surgery System, as a new strategy, is discussed in a part regarding operative management.

[Implementation of mutual information based medical image registration methods].

Image registration methods based on mutual information, including mutual information and normalized mutual information, have been accepted as the most accurate and efficient methods. But there are many fluctuations in the registration functions that hinder the optimization procedure and lead to registration failure in intra-modal registration. We found that besides the interpolation artifacts, the uncertainty of the changing of entropy with the changing of overlap also contributes to the fluctuations. The effect of interpolation artifacts can be eliminated, but it is difficult to eliminate the effect of uncertainty of entropy. Luckily, this effect is not significant in normalized mutual information. Normalized mutual information is more stable and robust than standard mutual information and its better performance and wider application can be expected.

[Current diagnostic and therapeutic approaches in liver injuries].

PURPOSE OF THE STUDY: The recent improvements in hospital care system (centralized specialized care) and the use of new imaging methods and modern technologies in surgical treatment have greatly enhanced successful outcomes of therapy in liver injury. The aim of the study was to evaluate the contribution of procedures included in the diagnostic-therapeutic algorithms to the treatment of blunt injury to the liver in our patient population. MATERIAL: Our group consisted of 43 patients with blunt injury to the liver who were treated at the Emergency Department between 1998 and 2002. In 28 patients, blunt injury was part of polytrauma, in 7 patients it was associated with thoraco-abdominal injury and, in 8 patients, it was the only trauma sustained. METHODS: The diagnosis and therapy were based on the algorithm currently used for treating liver injury at the Emergency Department. In addition to clinical examination and assessment of the actual status of hemodynamics, spinal computed tomography was carried out to establish the therapeutic procedure. Fourteen patients were treated conservatively according to the criteria of a non-surgical approach and 29 patients underwent urgent surgery. Indications for revision surgery included, apart from signs of ongoing abdominal bleeding related to liver injury, combined spleen and kidney trauma. All patients with thoraco-abdominal involvement had laparotomy; in addition, four underwent thoracotomy including repair of the lacerated lung by suturing and three patients required suturing of a rupture of the right part of the diaphragm. RESULTS: In the patients treated conservatively, 10 showed spontaneous regression of parenchymal hematomas and four had to be treated by suction drainage. Out of 29 patients operated on, five died with signs of an irreversible hemorrhagic shock from multiple trauma and one died of multiple organ failure. DISCUSSION: The principal criterion determining therapy in blunt liver injury is the patient's hemodynamic status; laparotomy is mandatory in intra-abdominal trauma with severe hemoperitoneum or when unstable hemodynamics is due to intraperitoneal bleeding. Non-surgical treatment of blunt liver injury, on condition that the established criteria are observed, has several advantages such as less stress for the patient, fewer intra-abdominal complications and fewer blood transfusions needed. The modern technologies used in the operative procedure are related to both a transient vascular occlusion and a strategy for selective care in liver trauma. CONCLUSION: 1. The treatment strategy in a patient with blunt liver trauma is determined by the patient's hemodynamic status; in a stable patient, spinal CT examination of the thorax and abdomen is mandatory. 2. Urgent laparotomy is indicated when the patient with blunt liver trauma is hemodynamically unstable due to diagnosed hemoperitoneum or suspected intraperitoneal bleeding. 3. Conservative therapy is applied when the criteria for non-surgical treatment are fulfilled. 4. Surgical strategy for blunt liver trauma is based on the extent and localization of the injury, the patient's overall status and severity of associated injuries. Resection of the injured parenchyma is indicated when laceration of a liver lobe occurs. 5. The prognosis of blunt liver injury is influenced, apart from hemorrhagic shock reversibility, by the severity of associated injuries in multiple trauma.

[Surgical therapy options for bleeding gastroduodenal peptic lesions].

INTRODUCTION: Mortality rate of bleeding into the upper GIT has remained relatively unchanged during the past 30 years, i.e. about 30%, even though the development of new technologies brought along substantial changes in diagnostic and therapeutic procedures. METHODOLOGY: This work deals with the surgical solution of bleeding into the upper GIT of peptic etiology. It covers a 5-year period (from January 1, 1999 until October 1, 2003) during which time the Regional Hospital in Pardubice admitted 1,310 patients with bleeding into the upper GIT of peptic etiology. 190 of them were hospitalized at the Surgical Clinic due to the developing hemorrhagic shock; the others were hospitalized at the Clinic of Internal Medicine. If it failed urgent endoscopy to stop the bleeding, the patient was referred to undergo an urgent surgery. If the bleeding was stopped by endoscopy yet it recurred after certain time, a second endoscopic homeostasis was attempted. If it failed, an urgent surgery was indicated. RESULTS: A total number of 24 patients underwent an acute surgery. A frequently used procedure was stomach resection, type BII, which was applied to a total number of 12 patients. However, this type of urgent surgery was accompanied with a relatively high number of complications. Reoperation had to be performed 4 times (33.3%). In one case (8.3%) for recurrent bleeding. In 12 patients one of the other procedures was performed: an injection and a trunkal vagotomy (3x), an injection and the ligation of the gastroduodenal artery (2x), proximal jejunum resection (1x), an injection accompanied with fundoplication according to Nissen-Rosseti (1x). Two of the patients who received this other group of procedures had to be reoperated for recurrent bleeding (16.7%). DISCUSSION: The decision about a suitable surgical procedure applicable to bleeding into the upper GIT after the failure of endoscopic homeostasis poses a substantial problem. It is necessary to choose from more radical procedures--resection--that stop bleeding reliably, yet their execution in an acute condition (often coinciding with the patient's hemorrhagic shock) results in a relatively large number of complications; and from less radical procedures that feature a smaller number of post-surgical complications yet that can be burdened with a larger percentile number of recurrent bleeding. Nearly the same number of serious recurrent bleeding in this study indicates that the appropriate choice of a procedure (according to the patient's current condition, ulcer localization, and associated diseases) makes both approaches (resection vs. a less radical procedure) similar as to the number of necessary reoperations after bleeding. CONCLUSION: The development of endoscopic methods introduced significant changes in the diagnostic-therapeutic algorithm of bleeding into the upper GIT. Nevertheless, the choice of an appropriate surgical procedure continues to present a relevant surgical issue.
