Chinyanga, H. M.; Kalangu, K. K.
Pain, the most urgent of symptoms usually signals the presence of potential or on-going injury to tissue which requires attention.The warning that pain provides is, therefore, a good thing and in a way friendly. When pain continues or resumes after the healing process of injury is complete, it is no longer signalling on-going tissue damage but becomes a disease in its own right. That, in essence, is the presentation of most chronic pain syndromes referred to Pain Clinics for investigation and treatment.

Chikungwa, M.T.; Jonsson, K.
Molecular oxygen is a colourless and odourless gas which is essential to life. It accounts for 21% of the atmospheric air. Apart from its central role in oxidative phosphorylation to produce biological energy in the form of adenosine triphosphate (ATP), molecular oxygen is used as substrate by two other enzyme systems for the killing of bacteria in the phagocytes and for collagen synthesis by the fibroblast during wound healing.18 In the immediate post operative period atmospheric oxygen might become inadequate for a number of reasons including hypoventilation due to central pharmacological depression, diffusion hypoxia and increased metabolic rate due to shivering (the so called halothane shakes).

Pulmonary valvotomy was one of the earliest cardiac operations attempted.1 Indeed the success with which it was done did much to dispel the myths of the impossibility of operating on the heart, and ushered in the subsequent advances in cardiac surgery. This is a report of a recent case, followed by a discussion of the relative merits of different techniques.

Objectives: To present a series of cases of survivors and non-survivors of traumatic asphyxia from a single mass casualty incident in Zimbabwe and a review of the literature.
Design: Descriptive case review.
Setting: Parirenyatwa Hospital is a tertiary referral 1 000 bed teaching hospital in Zimbabwe.
Results: Survivors (n = 4) displayed the classic signs of traumatic asphyxia of conjunctival haemmorhages, petechial blue-purple discoloration of head and neck and neurological findings of confusion or unconsciousness and convulsions. Non-survivors (n = 12) showed more varied signs but all showed petechiae and with a history of being crushed. On-site resuscitation and triage was absent, reducing the chance of identifying potential survivors at the scene.
Conclusion: The outcome in traumatic asphyxia is improved by rapid restoration of ventilation and circulation. The epidemiology of traumatic asphyxia in Zimbabwe is unknown but the conditions predisposing to it are present. Closer integration between hospital and pre-hospital services will permit better management of major trauma patients and mass casualty events.
