Nutrition in open abdomen.

Open abdomen is known as a serious consequence of various intra-abdominal pathologies. Initially, patients often have a life-threatening condition, sepsis or septic shock. Severe stress related malnutrition, mineral and fluid imbalance develop as metabolic consequences. Intestinal fistulas also occur as a frequent complication in patients with open abdomen. In such patients, a comprehensive approach is needed, including rehabilitation, nutritional support using optimal formulas, and local care for the open abdomen. Our case report presents a patient with open abdomen and enterocutaneous fistulation. A complex nutritional approach in the course of the disease is described and its importance is discussed. Finally, a summary of nutritional care for open abdomen patients is provided based on current recommendations.

[Our experience with chest wall stabilization]. / Nase zkusenosti se stabilizací hrudníku.

INTRODUCTION: An unstable chest wall is defined as a fracture of at least three adjacent ribs broken at least in two planes. As a result of impaired mechanical strength of the chest wall, paradoxical movements occur, resulting in insufficient pulmonary ventilation with the development of respiratory insufficiency with typical consequences - hypoxia, hypercapnia and acidosis. METHODS: In this paper we describe a group of 16 patients who underwent stabilization of the chest wall. The average age of the group was 56 years, the youngest patient was 23 and the oldest one 76 years old. There was an average of 6.1 broken ribs per patient, individually ranging from 4 to 8. In 11 cases, the stabilization was performed for a block fracture, in 5 cases for a serial fracture with a thoracic wall deformity. RESULTS: The average length of hospital stay was 19 days, the time from admission to surgery was 4.46 days, and the average duration of mechanical ventilation was 2.63 days. In our group, we had only one deep wound infection that was healed using vacuum therapy. Concerning other complications, there was one case of bronchopneumonia and one patient developed delirium. No redrainage for fluido- or pneumothorax was necessary. CONCLUSION: The main focus of this paper is on the active surgical approach to treatment of serial and block fractures of ribs with deformation or manifest instability of the chest wall. Not all patients with block fracture required stabilization, whereas 5 patients with serial fracture of the ribs were indicated for surgical revision for chest wall deformity and other complications.Key words: flail chest treatment indications.

[Initial experience with using uniportal VATS (SITS) to treat the implications of thoracic trauma in the 1st Department of Surgery of the Faculty of Medicine at Masaryk University and St. Annes Teaching Hospital in Brno]. / Iniciální zkusenosti s pouzitím "uniportal VATS (SITS)" prístupu pri osetrování dusledku hrudních traumat na I. chirurgické klinice LFMU a FNUSA v Brne.

Thoracic trauma represents a multidisciplinary therapeutic challenge requiring individualized approach to every patient. Continuous development and implementation of mini-invasive techniques in thoracic surgery pave way to so far unique attempts to establish video-assisted thoracic surgery for thoracic trauma as well. The indication is limited by hemodynamic stability of the patient, extent of the trauma, as well as by time required for the treatment. However, proper indication provides an unequivocal benefit in terms of postoperative pain, early mobilization and excellent cosmetic effect. Continuous reduction of the number of incisions down to monoportal approach is currently the peak of mini-invasive approach in thoracic trauma management. The aim of this work is to provide 3 case reports documenting the current spectrum of monoportal video-assisted surgery indication for thoracic trauma.Key words: uniportal VATS thoracic trauma.

[Assessment of thoracic trauma at the 1st Department of Surgery in Brno (1 January 2011 - 31 December 2015)]. / Poranení hrudníku na I. chirurgické klinice LF MU a FN USA v Brne (vyhodnocené období 1. 1. 2011 az 31. 12. 2015).

INTRODUCTION: The number of cases of thorax injury increased steadily between 2011 and 2015. This is probably related to a more active lifestyle of the younger generations and also to the increasing average age of citizens. The aim of the study was to show problems connected with thorax injury. METHOD: Our retrospective study evaluated a group of patients with thoracic injury (diagnosis codes S20-S29) in the period from 1 January 2011 to 31 December 2015 who were treated in our Department. RESULTS: We evaluated a group of 1,697 patients with thoracic injury were divided into five subgroups: 1) simple contusion of the thorax, 2) simple rib fractures, 3) contusion of the thorax with vertebral fractures, 4) serial, multiple rib fractures, 5) stab and gunshot injuries of the thorax. Each subgroup was analyzed independently and in detail. The number of thoracic injuries increased steadily, year on year. More than 40% of the patients were older than 60 years. In the group with simple rib fractures, the authors found 14 cases of pneumothorax (5.1%), which was drained in only 8 cases. The most common complications in the serial rib fractures group included pneumothorax (33 cases, 20%), hemothorax (28 cases, 16.9%) and lung contusion (15 cases, 9%). Stabilization of the thoracic wall was performed 16 times, out of the total of 26 multiple rib fracture cases (61.5%). CONCLUSIONS: Thorax injury is routinely encountered by surgeons. The authors recommend to pay particular attention not only to serious, but also to simple thorax injuries in very old patients, for instance those on anticoagulation therapy. Adequate caution also needs to be taken with serial rib fractures and flail chest and their treatment.Key words: thorax injury - rib fractures - hemothorax - pneumothorax.

[First Results of the German consulting center for infection control outbreak registry]. / Infektionen und Kolonisationen: Was können wir verbessern?

BACKGROUND: Outbreaks of infectious diseases and / or colonization pose an increasing burden on hospitals and the health system in general and can be a threat to patient safety. METHODS: At the end of 2013 we implemented a quality assurance registry of outbreak investigations performed by the Deutsches Beratungszentrum für Hygiene (German Consulting Center for Infection Control and prevention) in Freiburg. Now we analyzed the registered outbreaks until January 2015. RESULTS: Norovirus was the leading causative organism and gram negative bacteria dominated the group of bacterial outbreaks. Outbreaks lasted between 6 and 185 days. 24 % of outbreaks were related to colonization only. Within 29 outbreaks we had 187 infected patients, 50 colonized patients und 92 infected health care workers (64 x norovirus, 20 x influenza, 8 x scabies). No deaths were recorded. Several risk factors and improvement potentials for future outbreaks could be identified. CONCLUSION: Lack of staff compliance with vaccination or prophylactic therapy, misuse of personal protective equipment and lapses in absence from work for the required time can play an important role for prolonged outbreak situations esp. with viral outbreaks and scabies. A structured and goal directed outbreak management especially in the initial phase of an outbreak seems to be important for an efficient and fast termination of an outbreak.

[Stabilisation of the dislocated acromioclavicular joint and lateral fractures of the clavicle using a hook plate]. / Stabilizace luxace AC skloubení a zlomenin akromiálního konce klícku pomocí háckové dlahy.

INTRODUCTION: The aim of this study was to verify the hypothesis that the technique of stabilizing the acromioclavicular joint and lateral fractures of the clavicle using a clavicular hook plate can be considered a method of choice in the given types of injury. MATERIAL AND METHODS: The clinical part of the study included a total of 40 patients. The indication group was formed by patients with type III acromioclavicular joint dislocation, according to Tossy. As for lateral fractures of the clavicle, the patients of group II and types IIa, IIb according to revised Allman and Neers classification, underwent surgery. 40 patients with type III acromioclavicular luxation, operated on at the same clinic, were chosen as the control group; however, the technique of traction cerclage was used here. RESULTS: When evaluating our results, we recorded a lower occurrence of infectious complications in patients with a hook plate. No method failure or joint redislocation was observed in the hook plate group. There was no change in position even after the implant was removed. On the other hand, where traction cerclage was used, redislocation in the acromioclavicular joint occurred due to mechanical failure in 5 cases, in 15 cases mechanical implant failure was seen. As for patients with a hook plate, 11 cases showed irritation of the lower surface of the acromion. Statistical evaluation of parameters of the main set of patients was carried out in cooperation with the Institute of Biostatistics and Analyses of Masaryk University in Brno. CONCLUSION: Based on our results, the stabilisation of complete acromioclavicular separation and lateral end clavicle fractures using clavicle hook plate can be regarded as a suitable method for treating these lesions. Timely removal of the implant within 12 weeks of the intervention is needed to prevent irritation of the lower surface of the acromion.

Accurate quantification of mercapturic acids of styrene (PHEMAs) in human urine with direct sample injection using automated column-switching high-performance liquid chromatography coupled with tandem mass spectrometry.

Styrene is one of the most important industrial chemicals, with an enormously high production volume worldwide. The urinary mercapturic acids of its metabolite styrene-7,8-oxide, namely N-acetyl-S-(2-hydroxy-1-phenylethyl)-L-cysteine (PHEMA 1) and N-acetyl-S-(2-hydroxy-2-phenylethyl)-L-cysteine (PHEMA 2), are specific biomarkers for the determination of individual internal exposure to this highly reactive intermediate of styrene. We have developed and validated a fast, specific and very sensitive method for the accurate determination of the sum of phenylhydroxyethyl mercapturic acids (PHEMAs) in human urine with an automated multidimensional liquid chromatography-tandem mass spectrometry method using (13)C(6)-labelled PHEMAs as internal standards. Analytes were stripped from the urinary matrix by online extraction on a restricted access material, transferred to the analytical column and subsequently determined by tandem mass spectrometry. The limit of quantification (LOQ) for the sum of PHEMAs was 0.3 microg/L urine and allowed us to quantify the background exposure of the (smoking) general population. Precision within series and between series ranged from 1.5 to 6.8% at three concentrations ranging from 3 to 30 microg/L urine; the mean accuracy was between 104 and 110%. We applied the method to spot urine samples from 40 subjects of the general population with no known occupational exposure to styrene. The median levels (range) for the sum of PHEMAs in urine of non-smokers (n = 22) were less than 0.3 microg/L (less than 0.3 to 1.1 microg/L), whereas in urine of smokers (n = 18), the median levels were 0.46 microg/L (less than 0.3 to 2.8 microg/L). Smokers showed a significantly higher excretion of the sum of PHEMAs (p = 0.02). Owing to its automation and high sensitivity, our method is well suited for application in occupational or environmental studies.
