The acute coagulopathy of trauma is associated with hypoperfusion, metabolic acidosis and an increased mortality rate. Biochemical markers of hypoperfusion, namely base deficit (BD) and lactate, are commonly used to assess the degree of hypoperfusion. Early identification of hypoperfusion and acidosis using BD and lactate may help predict the development of coagulopathy in trauma patients and direct therapy. ⋯ BD but not lactate correlates with the development of the coagulopathy of trauma. The ISS showed a significant correlation with coagulation disturbances, and the combination of hypoperfusion and coagulopathy was associated with a significant increase in mortality.

The use of diverting colostomies in paediatric peri-anal burns: experience in 45 patients.
Peri-anal burns are common in children. Continual exposure to enteric organisms may lead to a contaminated burn wound, invasive sepsis, graft loss, scar contracture, anal and urinary malfunction, and delayed discharge from hospital. Use of a temporary diverting colostomy has been advocated to reduce complications. ⋯ Diverting colostomy has therapeutic advantages in a select group of paediatric burns patients in whom continual faecal soiling poses a threat to both graft and life.

Blunt abdominal trauma in childhood contributes significantly to both morbidity and mortality. Selective non-operative management of blunt abdominal trauma in children depends on both diagnostic and clinical factors. Computed tomography (CT) scanning is widely used to facilitate better management. Increased availability of CT may, however, result in its overuse in the management of blunt abdominal trauma in children, which carries significant radiation exposure risks. ⋯ CT scanning for blunt abdominal trauma in children is essential in the presence of appropriate clinical indications. Ease of access probably increases availability, but the rate of negative scans may increase. Management guidelines should be in place to direct CT scanning to cases in which clinical examination and/or other modalities indicate a likelihood of intra-abdominal injury. The principle of 'as low (radiation) dose as reasonably achievable' (ALARA) should be adhered to because of the increased radiation exposure risks in children.

Civilian popliteal artery injuries are associated with significant amputation rates. ⋯ The most significant factors associated with the high amputation rate of 37.5% were an ischaemic time longer than 7 hours, and the presence of a compartment syndrome.

Retropharyngeal abscesses are infections deep in the neck space that can pose an immediate life-threatening emergency, with potential for airway compromise and other catastrophic complications. In adults these abscesses can develop as a result of vertebral pyogenic osteomyelitis, tuberculosis of the spine, or external injuries caused by endoscopes or foreign bodies (e.g. fish bones). ⋯ Early diagnosis and treatment are necessary to prevent the serious complications of the disease. We present a case of tuberculous retropharyngeal abscess in an adult woman without tuberculosis of the cervical spine who was managed surgically by aspirating the retropharyngeal abscess transorally, together with antituberculosis treatment.
