Question: Abstract: The epidemiology of severe burns is analysed. From 1 September 1982 to 31 August 1983 75 patients, 27 females and 48 males were admitted to the Burns Unit in Copenhagen. The majority of burns were domestic and fire was the predominant cause. The most vulnerable areas were the arms and the legs, and small children still have the highest incidence of thermal injury. As predisposing factors were of significance in several accidents, the importance of further prevention is stressed.

Answer: Accidents, Home


Question: Abstract: CT scans were obtained in five patients who presented with abdominal pain and were found to have an abdominal aortic aneurysm without evidence of hypovolaemia. A periaortic haematoma and evidence of a rupture was found on scanning in three of the patients and confirmed at immediate operation. A retrospective diagnosis of rapidly expanding (acute) aneurysm was made in the other two patients in whom no other pathology was found at early elective operation. CT scanning is useful in differentiating small well-controlled ruptures from rapidly expanding aneurysms.

Answer: Acute Disease


Question: Abstract: The development of mouse and human embryos was assessed in human amniotic fluid to determine its suitability as a culture medium for human in vitro fertilization (IVF). Two-cell mouse embryos developed to blastocysts after 72 hours at rates similar to that in Whittingham's T6 + 10% fetal calf serum. Significantly more mouse embryos hatched in amniotic fluid. No difference was found between individual patient's amniotic fluids obtained at 16 to 21 weeks' gestation. A preliminary trial comparing amniotic fluid with T6 + maternal serum in human IVF showed no significant difference in fertilization rate and embryo development during 42 to 48 hours in vitro. Expanded blastocysts were obtained in amniotic fluid after 5 days in vitro. Four pregnancies were obtained in 9 patients' transferred embryos grown in amniotic fluid and with 2 or 12 patients' transferred embryos grown in T6 + maternal serum.

Answer:
Amniotic Fluid
