  • Release of neutrophil proteinase 4(3) and leukocyte elastase during phagocytosis and their interaction with proteinase inhibitors
  • 1992
  • Ingår i: Scandinavian Journal of Clinical and Laboratory Investigation. - : Informa UK Limited. - 0036-5513 .- 1502-7686. ; 52:8, s. 823-829

    • Neutrophil proteinase 4 (NP4) is a major neutral proteinase of the human polymorphonuclear (PMN) leukocyte, which is present in amounts similar to leukocyte elastase. NP4(3) is a potent, non-specific proteinase, which may degrade structural and soluble proteins in the tissues and body fluids, and it has been implicated as an important pathogenetic factor in lung emphysema. We have studied the release of elastase and NP4(3) in an in vitro model of phagocytosis, α1-pproteinase inhibitor (α1-PI) is the major plasma inhibitor of both leukocyte elastase and NP4(3), but α1-PI bound leukocyte elastase more readily than NP4(3). The basic conditions were designed so that some proteolytic activity was present in the medium. Addition of increasing amounts of Secretory leukocyte protease inhibitor (SLPI) to the incubation mixtures resulted in binding of leukocyte elastase to this inhibitor and extinction of free proteolytic activity against both natural and synthetic substrates. The progressive binding of leukocyte elastase to SLPI instead of α1-PI was paralleled by an increasing binding of NP4(3) to α1-PI. SLPI is a potent inhibitor of leukocyte elastase and cathepsin G, and although it lacks inhibitory effect on NP4(3), it may obviously indirectly aid in the binding and inhibition of NP4(3) to α1-PI, by taking care of at least part of the leukocyte elastase. As a specific NP4(3)-inhibitor is not readily available for therapeutic use, this effect may prove useful under in vivo conditions and enhance the protective effect of administered recombinant human SLPI.

  • 1994
  • Ingår i: Resuscitation. - 0300-9572. ; 27:3, s. 181-7
  • Tidskriftsartikel (refereegranskat)abstract
    • A two-tiered ambulance system with a mobile coronary care unit and standard ambulance has operated in Gothenburg (population 434,000) since 1980. Mass education in cardiopulmonary resuscitation (CPR) commenced in 1985 and in 1988 semiautomatic defibrillators were introduced. Aim: To describe early and late survival after cardiac arrest outside hospital over a 12-year period. Target population: All patients with prehospital cardiac arrest in Gothenburg reached by mobile coronary care unit or standard ambulance between 1980 and 1992.

    • Background: A two-tiered ambulance system with a mobile coronary care unit and standard ambulance has operated in Gothenburg (population 434 000) since 1980. Mass education in cardiopulmonary resuscitation (CPR) commenced in 1985 and in 1988 semiautomatic defibrillators were introduced. Aim: To describe early and late survival after cardiac arrest outside hospital over a 12-year period. Target population: All patients with prehospital cardiac arrest in Gothenburg reached by mobile coronary care unit or standard ambulance between 1980 and 1992. Results: The number of patients with cardiac arrest remained fairly steady over time. Among patients with witnessed ventricular fibrillation, the time to defibrillation decreased over time. The proportion of patients in whom bystander initiated CPR was increased only moderately over time. The proportion of patients given medication such as lignocaine and adrenaline successively increased. The number of patients with cardiac arrest who were discharged from hospital per year remained steady between 1981 and 1990 (20 per year), but increased during 1991 and 1992 to 41 and 31 respectively. Conclusions: Improvements in the emergency medical service in Gothenburg over a 12-year period have lead to: (1) a shortened delay time between cardiac arrest and first defibrillation and (2) an improved survival of patients with cardiac arrest outside hospital probably explained by this shortened delay time.

  • Oral findings in a group of newborn Swedish children.
  • 1994
  • Ingår i: International Journal of Paediatric Dentistry. - 0960-7439. ; 4:2, s. 67-73
  • Tidskriftsartikel (refereegranskat)abstract
    • Oral examinations were performed of 1021 newborn Swedish children, of whom 101 were re-examined after 2-3 or 4-5 months. The most common findings, registered in 74.9% of the children, were of oral mucosal cysts situated either palatally or on the alveolar ridges. The majority of the palatal cysts disappeared shortly after birth, and some alveolar cysts appeared after birth. Ankyloglossia was found in 2.5% of the children, and Fordyce spots in 1.0%. No natal teeth were found. The upper labial frenum was attached to the crest of the alveolar ridge in 76.7% of the children, palatally in 16.7% and buccally in 6.7%. The relationship of the alveolar ridges was recorded: the anterior segment of the mandibular ridge was distal to the maxillary in 99% of cases, and, posteriorly, the mandibular ridges were lingual to the maxillary in 97.6%. An open bite was found in 39.8% of the children.

  • Effect of bystander initiated cardiopulmonary resuscitation on ventricular fibrillation and survival after witnessed cardiac arrest outside hospital
  • 1994
  • Ingår i: British Heart Journal. - : BMJ Group. - 0007-0769. ; 72:5, s. 408-412
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE--To describe the proportion of patients who were discharged from hospital after witnessed cardiac arrest outside hospital in relation to whether a bystander initiated cardiopulmonary resuscitation. PATIENTS--All patients with witnessed cardiac arrest outside hospital before arrival of the ambulance and in whom cardiopulmonary resuscitation was attempted by the emergency medical service in Gothenburg during 1980-92. RESULTS--Cardiopulmonary resuscitation was initiated by a bystander in 18% (303) of 1,660 cases. In this group 69% had ventricular fibrillation at first recording compared with 51% in the remaining patients (P < 0.001). Among patients in whom cardiopulmonary resuscitation had been initiated by a bystander 25% were discharged alive versus 8% of the remaining patients (P < 0.001). Independent predictors of survival were in order of significance: initial arrhythmia (P < 0.001), interval between collapse and arrival of first ambulance (P < 0.001), cardiopulmonary resuscitation initiated by a bystander (P < 0.001), and age (P < 0.01). Among patients who were admitted to hospital alive 30% of patients in whom cardiopulmonary resuscitation had been initiated by a bystander compared with 58% of remaining patients (P < 0.001) had brain damage and died in hospital. Corresponding figures for death in association with myocardial damage were 18% and 29% respectively (P < 0.01). CONCLUSIONS--Cardiopulmonary resuscitation initiated by a bystander maintains ventricular fibrillation and triples the chance of surviving a cardiac arrest outside hospital. Furthermore, it seems to protect against death in association with brain damage as well as with myocardial damage.

  • Predictors of early and late survival after out of hospital cardiac arrest in which asystole was the first recorded arrhythmia on scene
  • 1994
  • Ingår i: Resuscitation. - : Elsevier Ireland Ltd. - 0300-9572 .- 1873-1570. ; 28:1, s. 27-36
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: A large proportion of patients who suffer out-of-hospital cardiac arrest have asystole as the initial recorded arrhythmia. Since they have a poor prognosis, less attention has been paid to this group of patients. Aim: To describe a consecutive population of patients with out-of-hospital cardiac arrest with asystole as the first recorded arrhythmia and to try to define indicators for an increased chance of survival in this population. Setting: The community of Gothenburg. Patients: All patients who suffered out-of-hospital cardiac arrest during 1981 to 1992 and were reached by our emergency medical service (EMS) system and where cardiopulmonary resuscitation (CPR) was attempted. Results: In all there were 3434 cardiac arrests of which 1222 (35%) showed asystole as the first recorded arrhythmia. They differed from patients with ventricular fibrillation by being younger, including more women and having a longer interval between collapse and arrival of the first ambulance. In all 90 patients (7%) were hospitalized alive and 20 (2%) could be discharged from hospital. Independent predictors for an increased chance of survival were: (a) a short interval between the collapse and arrival of the first ambulance (P < 0.001) and the time the collapse occurred (P < 0.05). Initial treatment given in some cases with adrenaline, atropine and tribonate were not associated with an increased survival. Conclusions: Of all the patients with out-of-hospital cardiac arrest, 35% were found in asystole. Of these, 7% were hospitalized alive and 2% could be discharged from hospital. Efforts should be made to improve still further the interval between collapse and arrival of the first ambulance.
