Abstract
Introduction Long Acting Buprenorphine (LAB) – Buvidal (CAM2038) – is a prolonged release treatment for opioid dependence in adults. Its extensive use was funded by Welsh Government during the pandemic in Wales and it has been found to be a significantly better than oral medications in improving quality of life, possibly through providing allostatic craving and anxiety reduction Objectives This is a case series of 10 patients who were referred to Community Addiction Services in North and South West Wales with OAD. Methods Patients were mainly using Codeine or Tramadol and were referred due to either ongoing illicit use or via primary care services requesting support. As part of the pandemic initiative, they were initiated on Buvidal and followed up. Results All ten patients successfully started on Buvidal without significant issues. As a group, if transferred straight to Buvidal, they tended to have fewer significant withdrawal symptoms prior to starting on the Buvidal compared to those on Methadone or Heroin. They were treated on the usual range of Buvidal doses (1 on 64mg, the others on 96-128mg monthly). They have all stabilised and successfully moved on with their lives on Buvidal. One has used the time on Buvidal to have psychological input around past traumas and successfully detoxified in the community using Buvidal. Conclusions Recommendations for services considering OAD - it is a surprisingly effective treatment which is easy to start. It has the scope for being both an effective OAD recovery medication and a potentially simple detoxification strategy for this patient group.

Abstract
Introduction We have been using LAB (Buvidal) in Cardiff after its pandemic use was funded by Welsh Government. Objectives We wished to review the benefits of introducing LAB (Buvidal) into treatment during the pandemic. Methods This service development review of the first 73 patients treated with LAB (24mg/96mg rapid titration Welsh protocol) was analysed using Kaplan-Meier survival curves. Results 43 (58%) male, 30 (41%) female. <25years=1, 38 (52%) aged 25-40, 34 (47%) 40-55. Prior to LAB 14% (10 people) using Espranor, 8% (6) Buprenorphine, 28% (20) Methadone. 50% (36) illicit opiates (mainly Heroin). We had continuous data for patients for up to 9 months of LAB. Two stopped for non-discontinuation reasons: One wanted to detox, one died of natural causes (LAB-unrelated). Both were excluded from discontinuation rate analysis. 55 people have data for over a month. Of these, 11 discontinued treatment. 80% remained on LAB for 1 month or more [95%CI 67-90%]. Kaplan-Meier plots showed similar discontinuation rates when comparing different OST programmes or none prior to LAB, and comparing by age, sex and initial illness severity (CGI severity). These rates all far exceeded data for traditional OST. CGI scores dramatically improved, even at one week. By month 2 all scores “much improved” or “very much improved”. Conclusions Buvidal (LAB) has 80% retention rates, regardless of underlying prescribed/illicit opioid /demographics. The commonly held belief that those on heroin are further from Recovery than those more stable on OAD may be incorrect. LAB may be a more acceptable and useful first line therapy that other OSTs Disclosure

Abstract
Much attention has been paid to understanding the traits associated with crop performance and the associated underlying physiological mechanisms, with less effort done towards combining different plant scales, levels of observation, or including hybrids of autogamous species. We aim to identify mechanisms at canopy, leaf and transcript levels contributing to crop performance under contrasting nitrogen supplies in three barley genotypes, two hybrids and one commercial line. High nitrogen fertilization did not affect photosynthetic capacity on a leaf area basis and lowered nitrogen partial factor productivity past a certain point, but increased leaf area and biomass accumulation, parameters that were closely tracked using various different high throughput remote sensing based phenotyping techniques. These aspects, together with a larger catabolism of leaf nitrogen compounds amenable to sink translocation, contributed to higher crop production. Better crop yield and growth in hybrids compared to the line was linked to a nitrogen-saving strategy in source leaves to the detriment of larger sink size, as indicated by the lower leaf nitrogen content and downregulation of nitrogen metabolism and aquaporin genes. While these changes did not reduce photosynthesis capacity on an area basis, they were related with better nitrogen use in the hybrids compared with the line.

Abstract
AIM The aim of our study is to introduce a new objective method of perioperative evaluation of the size of diaphragmatic defect to enable comparison of results among various centres and methods used for diaphragmatic reconstruction. MATERIALS AND METHODS Prospective observational study of neonates with congenital diaphragmatic hernia (CDH) and respiratory distress within 24 h of birth operated on from January 2009 to December 2011. Weight, length, thoracic shape and the diameters of diaphragmatic defect were measured. To determine the relative size of the defect, a defect-diaphragmatic ratio (DDR = defect area:diaphragm area × 100) was calculated. The measured and calculated data were subsequently compared between Gore-Tex patch group (GT) and primary repair group (PR). Mann-Whitney U test was used for statistical analysis. RESULTS Forty-seven patients with CDH were admitted during study period. The overall survival rate was 79 % (37/47). Preoperative stabilization was achieved in 85 % (40/47). Survival of operated neonates was 93 % (37/40). Diaphragmatic reconstruction with Gore-Tex patch was used in 7 neonates (17 %), and primary repair in 33 (83 %). Mortality in Gore-Tex group was 29 %; mortality in primary repair group was 3 %. Data of anthropometric measurement were complete in 34 children (5 GT and 29 PR). Significant differences were found between GT group and PR group in the size of diaphragmatic defect with the transverse and sagittal diameters of defect (48.0 ± 5.7 vs. 30.1 ± 5.9, P < 0.00061; 34.0 ± 12.5 vs. 16.0 ± 7.3, P < 0.0022) and DDR (18.29 ± 4.60 vs. 5.77 ± 3.28, P < 0.0005), respectively. CONCLUSION The value of DDR as an objective criterion of the extent of diaphragmatic defect was confirmed by the close correlation between DDR and feasibility of primary repair in the study group. This objective assessment of defect size may improve comparing various surgical techniques and results of different centres, and thus facilitates sharing experience with management of neonates with CDH.

Abstract
Generalized Anxiety Disorder (GAD) may involve hypo-responsiveness of noradrenaline a2 receptors. To test this hypothesis, we used (99m)Tc-hexa-methyl-propylene-amine-oxime (HMPAO) Single Photon Emission Computed Tomography to measure regional cerebral perfusion in patients with untreated GAD, venlafaxine-treated patients and healthy controls during word generation before and after clonidine. Concurrent psychological and physiological measures supported noradrenergic hypofunction in GAD in some cases. A single-day split-dose technique was used. Images were processed using SPM5 (Institute of Neurology). Factorial analysis revealed no significant results. Exploratory analyses were done. Regional perfusion during verbal fluency differed by group pre-clonidine. Compared with healthy controls, patients with untreated GAD displayed increased perfusion in the left Broca's area and left occipitotemporal region. Treated GAD patients displayed increased cerebellar perfusion bilaterally. Clonidine was associated with different changes in cerebral perfusion in each group. Increases were seen in the right supra-marginal gyrus in healthy subjects, in the left pre-central gyrus in treated GAD patients and in the right cerebellum and middle frontal gyrus in untreated GAD patients. Despite these differences, the findings were not consistent with a noradrenergic hypo-responsiveness hypothesis, as the treated group showed a different pattern of response rather than a normalization of response.

Abstract
The purpose of this study was to evaluate the outcome in neonates with congenital diaphragmatic hernia (CDH) either presenting within the first 24 h of life or diagnosed prenatally. The study was particularly focused on the time of onset of respiratory distress and on the use of the Gore-Tex (GT) patch for diaphragmatic reconstruction. Records of 104 neonates with CDH were retrospectively reviewed. The data were analyzed by ANOVA, Kruskal-Wallis test or chi (2) test as appropriate. The result showed that the overall survival rate was 73.1% (76/104). Survival of operated neonates was 91.6% (76/83). Postnatally diagnosed neonates with the onset of respiratory distress within the first minute of life survived in 67%, with the onset between 2 and 10 min survived in 89%, whilst neonates with the onset of respiratory distress after l0 min survived in 100% (P = 0.007). Birth weight, gestational age, time of onset of respiratory distress and Apgar score significantly differed between survivors and nonsurvivors. Primary closure of the diaphragmatic defect was performed in 62 patients while the GT patch was used in 21 patients. The survival of patients with a large defect treated with a GT patch was lower (76.2 vs. 96.8%, P = 0.003). There was only one case of recurrence in our series with the GT patch. Survival depends on the time of onset of respiratory distress and size of the defect, both of which correlate with the degree of pulmonary hypoplasia. The term high-risk CDH is appropriate only for children with respiratory distress within the first 10 min of life and those diagnosed prenatally. The GT patch is a suitable material for the diaphragmatic reconstruction; we suppose that the recurrence is caused by incorrect attachment of the patch to the thoracic wall.

Abstract
The occurrence of coexisting congenital diaphragmatic hernia (CDH) and esophageal atresia (EA) with distal tracheoesophageal fistula (TEF) is extremely rare and is considered highly lethal. The combination of CDH with EA/TEF and truncus arteriosus communis (TAC) has not been reported in the literature to date. The authors describe a premature neonate with this association.

Abstract
OBJECTIVE To evaluate some perinatal and neonatal risk factors of occurrence of necrotising enterocolitis (NEC) and the current possibilities of treatment. DESIGN A retrospective data analysis. SETTING Mother and Child Care Institute, Prague. METHODS The clinical course in 28 neonates treated for NEC on the worksite of the authors in the period 1999-2003. Only neonates with NEC in the second and third Bell's stages were included in the group. RESULTS From a group of 14,275 neonates born during the reference period, NEC was diagnosed in 28 neonates. In all cases, they were neonates with very low birth weight (VLBW). The average gestation age was 26.6 weeks (the range was 23-35; the median was 25.5); the average birth weight was 822 grams (the range was 340-1,490g; the median was 735). Incidence was between 1.08 and 2.37/1,000 live births (the average was 1.94). On the average, NEC occurred on the 17th day after birth (the range was 5-59; the median was 14). 14 neonates (50%) in the acute stage of NEC were operated on; 9 children (32%) were only treated conservatively. In eight children at the acute stage, who were operated on, divided ileostomy was created; in four children, a T-drain was used for removal of the intestinal content and an abdominal drain was used for this purpose in one child. Repeated surgery was necessary in five children. Of the conservatively treated ones, five children recovered as a result of conservative treatment and four children died as a result of fast progression of NEC without surgical treatment. All the children treated for patent ductus arteriosus (PDA) with Indometacin died. The overall mortality in the group was 39.3% (11 children died). CONCLUSION Prematurity seems to be the common denominator of the occurrence of NEC. Treatment of NEC in highly immature neonates with birth weight below 1,500g requires comprehensive cooperation of a neonatologist and a children's surgeon. Resection of a necrotic intestine with creation of a stomy remains a standard procedure, which is followed in unstable neonates with a localised form of the illness. Prevention of premature birth, antenatal steroids, frequent feeding (trophic feeding) and the corresponding correction of water management seem to be a reasonable strategy to reduce the incidence of NEC. The resulting incidence, mortality, the time of the occurrence of NEC and the therapeutic procedures are within the limits stated in the international literature.

Abstract
OBJECTIVE To assess the risk and the degree of possible unfavourable development in neonates with bronchopulmonal dysplasia and with congenital diaphragmatic hernia. DESIGN Longitudinal monitoring of the mental, motoric and neurological development until the age of 2 years. Comparison of the findings with the result of polygraphic examination carried out at the expected time of birth. METHODS The following children were monitored: a) 38 children with bronchopulmonal dysplasia born between the 24th and 33rd post-conception weeks; b) 18 children with congenital diaphragmatic hernia, of whom 3 children were born between the 34th and 36th post-conception weeks, while the remaining 15 children were born on the expected date. All children underwent polygraphic examinations (EEG - 8 channels, respiration, EKG, EOG and EMG) between the 38th and 42nd post-conception weeks. During the 1st and the 2nd years, their psychomotoric development and neurological status were repeatedly evaluated according to Bayley and Vlach, respectively. RESULTS Up until the 2nd year of life, approximately 2/3 of the children in both monitored groups were developing favourably or satisfactorily. However, the development of the remaining 1/3 was not favourable: The children were mentally or motorically retarded and/or cerebral palsy developed in them. The polygraphic examination in the neonatal period predicted the favourable or unfavourable development of the monitored children with high probability. CONCLUSION The study showed that in accordance with the data stated in the literature, the development of neural functions is seriously affected in a relatively high percentage of neonates with severe pneumopathy. Neonatal polygraphy can contribute to timely determination of the prognosis for these children. Children with serious neonatal pneumopathies need to be provided with dispensary care on a long-term basis, and professional consultancy and intervention programmes need to be ensured for them.

Abstract
AIM The aim of this study is to assess a contemporary treatment potential for necrotizing enterocolitis in newborns with birth weights under 1000 g. METHODOLOGY AND SUBJECTS: This is a retrospective study of clinical and pathological data in a group of 19 newborns with birth weights under 1000 g treated for necrotizing colitis (NEC) by the authors' team from 1999 to 2003. Only newborns with the second and third grade NEC according to Bell were included in the trial group. RESULTS The trial group included 19 newborns born in the 26th gestation week, on average (ranging from 23- to 31) with a mean birth weight of 711 grams (the range between 460-980 g). Their NEC appeared on the 18th postnatal day, on average (the range between 6-59). Ten newborns were operated in the acute stage of their NEC, nine were treated conservatively. Five infants operated in the acute stage had separational ileostomy conducted, four had a T-drain introduced and one had an abdominal drain introduced. In the conservatively managed group, three infants were consequently operated for intestinal strictures following their NEC, two recovered during the conservative treatment and four exited due to a fast progress of their NEC without surgery. The total mortality rate of the trial group was 42% (8 infants exited). CONCLUSION The NEC treatment in the extremely immature newborns with birth weigts under 1000 g requires complex cooperation of a neonatologist and a paediatric surgeon. The necrotic intestine resections followed by stomic procedures remain standard procedures in unstable newborns with a localised form of the disease.

Abstract
OBJECTIVE Nosocomial infections caused by the coagulase-negative staphylococci are among the most frequent complications in an intensive care unit for neonates. The authors describe three cases of successful treatment of this complication in which the new antibiotic Linezolide was used. DESIGN Analysis of three clinical cases. SETTING Mother and Child Care Institute, Prague. METHODS Description of cases of nosocomial sepsis in 3 immature neonates where the usual treatment of multiresistant strains of coagulase-negative staphylococci, based on the use of Vankomycin, was not successful. CONCLUSION Administration of Linezolide proved to be very effective in all of the described cases. In spite of the high effectiveness and relative safety of this preparation, its precise role in the treatment of infection-related complications caused by coagulase-negative staphylococci has not yet been established. For the time being, we recommend administering this preparation only in strictly indicated cases after the usual therapy fails.

Abstract
In this study the authors present a method of conversion of external fixations to closed intramedullary ones in the treatment of complicated diaphyseal fractures of the calf and femur. According to the conditions, the fixation is secured by a pin. The above mentioned procedure is advantageous especially in cases of patients with open fractures, in patients with polytraumas as well as in patients with a threatening or with a present compartment syndrome. Treatment of the above fractures is not always simple and represents a serious problem in everyday traumatological practice. Treatment of fractures using the above procedure has very good results with a minimum of complications. Although, nowadays, the skeletal defect can be solved and therefore the bearing capacity of the extremity be renewed, damages to the muscles are often irreparable and cause a permanent invalidity.

BACKGROUND Treatment of the Congenital Diaphragmatic Hernia in neonates with early manifestations has been accompanied with significant mortality. Authors present the treatment protocol employed in such children and results from the period January 1994 to December 2003. METHODS AND RESULTS Since January 1994 to December 2003 96 children were cured for the Congenital Diaphragmatic Hernia. Ratio F:M was 36:60. 29 children (30%) were diagnosed prenatally, the remaining newborns were diagnosed on the basis of thoracic X-ray, which was required for the early signs of respiratory insufficiency. The postnatal treatment protocol included circulation-ventilation stabilisation, operation, early extubation and initiation of the peroral nourishment. Altogether 78 (81%) of children were operated after the stabilization using the standard laparotomy method, 5 children (6%) were operated with extra corporal membrane oxygenation, in 20 children (26%) a Goretex patch was used to cover an extensi e defect in the diaphragm. Overall survival was 74%, survival of operated children was 91%, 75% of children with a patch survived, survival of children operated with ECMO was 40%. Relapse occurred in one child (1%) with a patch. CONCLUSIONS Specification of the prenatal diagnosis and collection of patients with CDH into tertiary centres with ECMO possibility can improve prognosis of neonates with the malformation.

Abstract
The authors describe the group of 23 patients (16 women, 7 men), who were operated during 2000-2003 on ulna-carpal impingement or the syndrome of ulna impact on the basis of "plus variant" of ulna or also "long ulna". There was a fracture of distal radius in anamnesis of all these patients. The condition was solved in 18 patients (mean age 51 years) by reducing the ulna by 4.5 cm on the average (range 2-10 mm). In five patients (mean age 49 years), the radius-ulna desis sec. Sauvé-Kapandij was performed. The results are evaluated with the time lapse of 6 months on the average (range 3-26). The resulting evaluation indicates that in all patients, who were not affected by radius-ulna arthrosis, a simple reduction of ulna resulted in an improvement of the extent of movements and improved subjective complaints. Patients with radius-ulna arthrosis, where the ulna-carpal impingement was solved by radius-ulna desis, suffer from worse long-term functional results. The authors also analyze complications of the interventions. Posttraumatic deformations in the area of distal forearm should be solved early before degenerative changes develop. The is the only way how to expect good results of the operation and favorable effect for the patient.

Abstract
When formulating indications for surgery of the thoracic outlet syndrome (TOS) the authors use as a basis their own experience with treatment of 42 patients and data from the literature. The basis is the fact that to the great majority of patients at the time after establishment of the diagnosis comprehensive and systematic rehabilitation care was not available either because lack of time or due to the absence of a department within their reach which could ensure adequate care. The authors discuss the reasons why they prefer after accurate establishment of the diagnosis a primary surgical approach and elimination of the cause of further mechanical damage of the neurovascular bundle with necessary and obvious continuation with long-term intensive rehabilitation. This is a reverse procedure than that recommended by some others concerned with this problem.

Abstract
The authors describe very rare complication (pseudopleural effusion) after peripheral venous cannulation (Introcan-W 24G3/4 through v. axilaris) in extremely premature newborn with birth weight 600 grams, which lead to worsening of patient's respiratory insufficiency. Ultrasonographic examination confirmed extrapleural process without necessity of surgical intervention. Cannula extraction and infusion interruption were followed by spontaneous regression of the complication, thereafter artificial ventilation was discontinued and baby was discharged.

Abstract
The authors present their experience with the reconstruction of the diaphragm with a synthetic polytetrafluoroethylene patch in a group of 66 neonates with a congenital diaphragmatic hernia. After preoperative stabilization 53 neonates (80%) were operated, simple reconstruction of the diaphragm was made in 39 neonates (74%), reconstruction of the diaphragm with a polytetrafluoroethylene patch was indicated in 14 patients (26%). Nine patients recovered after reconstruction of the diaphragm by a synthetic patch without complications. The only relapse of diaphragmatic hernia when using a patch was recorded in a neonate with a bilateral diaphragmatic hernia, sternal cleft and omphalocele. After simple reconstruction of the diaphragm there was no relapse of hernia. The total mortality in the group was 27% (18 neonates). After surgery five neonates died. Two of them died of serious haemorrhagic complications during extracorporeal membrane oxygenation and three died after operations performed at borderline oxygenation and ventilation values and subsequent deterioration of the general condition. In four of them a polytetrafluoroethylene patch (GORE-TEX) was used. Reconstruction of the diaphragm by a polytetrafluoroethylene patch is a suitable surgical method in the treatment of neonates with a congenital diaphragmatic hernia. Indication for the use of a patch is agenesis of the diaphragm and major diaphragmatic defects with hypoplastic borders. The use of a non-absorbable synthetic patch is from the aspect of the long-term effect on growth and the development of skeletal deformities equivocal and will call for further detailed studies.

Abstract
The authors describe the case of newborn with laparoschisis in whom severe idiopathic pulmonary hypertension during postoperative period developed and initiation of extracorporeal membrane oxygenation (ECMO) to maintain circulatory stability and adequate oxygenation was necessary. ECMO was performed for 75 hours with maximum extracorporeal support up to 50% of cardiac output (Biomedicus pump BP 50, Jostra oxygenator M8). Patient was successfully weaned and switched to conventional ventilation and nitric oxide inhalation with consequent extubation. No bleeding complications were observed during ECMO in connection with surgical repair of laparoschisis.

Abstract
Carbon-11 labelled RS-15385-197 and its ethylsulphonyl analogue, RS-79948-197, were evaluated in rats as potential radioligands to image central alpha2-adrenoceptors in vivo. The biodistributions of both compounds were comparable with that obtained in an earlier study using tritiated RS-79948-197 and were consistent with the known localisation of alpha2-adrenoceptors. The maximal signals (total to non-specific binding) were, however, reduced, in the order [11C]RS-79948-197 < [11C]RS-15385-197 < [3H]RS-79948-197, primarily due to the difference in radiolabel position (O-methyl for carbon- 11 compared with S-ethyl for tritium). This resulted in the in-growth of radiolabelled metabolites in plasma, which, in turn, contributed to the non-specific component of brain radioactivity. Nonetheless, the signal ratio of approximately 5 for a receptor-dense tissue compared with the receptor-sparse cerebellum, at 90-120 min after radioligand injection, encouraged the development of [O-methyl-11C]RS-15385-197 for human positron emission tomography (PET). Unfortunately, in two human PET scans (each of 90 min), brain extraction of the radioligand was minimal, with volumes of distribution more than an order of magnitude lower than that measured in rats. Following intravenous injection, radioactivity was retained in plasma and metabolism of the radiolabelled compound was very low. Retrospective measurements of in vitro plasma protein binding and in vivo brain uptake index (BUI) in rats demonstrated a higher protein binding of the radioligand in human compared with rat plasma and a lower BUI in the presence of human plasma. It is feasible that a higher affinity of RS-15385-197 for human plasma protein compared with receptor limited the transport of the radioligand. Although one of the PET scans showed a slight heterogeneity in biodistribution of radioactivity which was consistent with the known localisation of alpha2-adrenoceptors in human brain, it was concluded that [O-methyl-11C]RS-15385-197 showed little promise for routine quantification of alpha2-adrenoceptors in man.

Abstract
The diagnosis and treatment of congenital diaphragmatic hernia, CDH, is an interdisciplinary problem. The patient concentration with prenatally diagnosed CDH for comprehensive examination with subsequent decision on the type of delivery improves the prognosis of patients with CDH. Introduction of corticoid therapy in prenatally assessed CDH reduces dysfunction and surfactant deficiency and can reduce the degree of respiratory failure during delivery. In very early prenatally assessed CDH it is possible to consider the possibility of combined corticoid and TRH (thyroxin releasing hormone) treatment of CDH. The authors submit also contemporary possibilities of prenatal intervention treatment of CDH (indication criteria for reconstruction operations of foetal surgery, intrauterine closure of the trachea and artificial laparoschisis). The concentration of patients with postnatally diagnosed CDH and a severe grade of acute respiratory insufficiency in a department with conventional and non-conventional artificial pulmonary ventilation incl. inhalation of NO oe extracorporeal membrane oxygenation, ECMO, is a further step towards optimation of treatment. Continuous evaluation of parameters of pulmonary functions during the pre- and postoperative period may prove that a therapeutic protocol with delayed surgery is useful.

Abstract
We describe a novel instrument which is capable of measuring the uptake of radioligand in human organs in vivo with the administration of very small doses of positron-emitting radioligands. This technique readily detects the displacement or reduced uptake of radioligand when a competitive agonist or antagonist is administered. This system provides no tomographic information, but the small radioactive doses involved mean that investigations can be repeated at regular intervals and that female volunteers can also participate. We administered [(11) C]flumazenil, [(11)C]diprenorphine, [(11)C]meta -hydroxyephedrine (MHED) and [(11)C]RTI 55 to healthy male volunteers and performed control, pre-loading and displacement experiments. These demonstrate the feasibility of using this technique to investigate benzodiazepine and opiate receptor occupancy, as well as occupancy at dopamine, noradrenaline and serotonin (5-HT) re-uptake sites. This method is likely to be useful in pharmacokinetic/pharmacodynamic experiments, in drug development and discovery and in the development of novel imaging radioligands.

Abstract
The authors give an account of 11 patients hospitalized in 1975-1988 in the Traumatological Research Institute in Brno with a subcapsular haematoma of the liver. In case of suspected liver injury they use nowadays examination by ultrasound. Laparotomy must not be delayed in patients with unstable vital functions only because of various diagnostic examinations. The therapeutic success in liver injuries depends on early operation, correct resuscitation and selection of an optimal surgical procedure which depends above all on the type and grade of severity of the injury.

Abstract
The authors give an account of 69 patients hospitalized in 1975-1986 in the Traumatological Research Institute in Brno on account of liver injuries. The mean age of the patients was 38.3 years. The liver injury was very frequently associated with serious craniocerebral injuries, with injuries of the chest and other intraabdominal organs and the total lethality was 62.3%. The most frequent cause were traffic injuries (50 cases). Blunt liver injuries accounted for 92.8% of the cases.

Abstract
The authors investigated in experiments on rabbits healing of liver incisions under various circumstances: spontaneous healing, liver incisions treated by suture by application of the tissue glue Tissucol, the collagenous haemostatic felt Collastypt combined with one stitch. Healing was followed up after several time intervals. From normal, i.e. the group of spontaneous healing, differed the groups treated by Tissucol and Collastypt where marked encapsulating fibrous tissue reactions round the necroses on the wound margins were found with numerous eosinophils as a transient phenomenon. The final result (with a maximum of cca two months) was adequate in all groups--as a rule a thin fibrous tissue scar with few remnants of atrophic hepatic trabeculae. In the treatment of small injuries it seems best to use the collagenous haemostatic Collastypt. In the treatment of sutures in rare instances a large number of leucocytes was found in the area of the necrosis and stitches, perhaps as result of contamination of the wound or sewing material.
