The short-term outcome of severe blunt head injury as reported by relatives of the injured persons.

A close relative of 55 severely head injured adults (post-traumatic amnesia greater than or equal to 2 days) was interviewed 3, 6 and 12 months after injury to obtain information about psychosocial changes in the patient. The problems most frequently reported were emotional disturbances, poor memory, and subjective symptoms, with physical disability much less common. The amount of stress experienced by relatives did not diminish between 3 and 12 months, and was related to the incidence of mental and behavioural changes in the patient. The question of whether or not compensation was being claimed did not appear to influence the outcome.

Isolated ureteral injury secondary to transperitoneal stab wound.

The patient reported suffered a transperitoneal stab wound resulting in the isolated complete transection of the left upper ureter. In spite of immediate exploratory laparotomy, the time of recognition of the injury was delayed. The treatment consisted of an ellipitcal spatulated everting uretero-ureterostomy with interrupted fine chromic catgut over a stenting ureteral catheter. The postoperative course was smooth and the final result excellent. The importance of intravenous urography in penetrating abdominal or flank trauma cannot be overemphasized. This is the first reported case of isolated ureteral injury secondary to transperitoneal stab wound.

Inter-laboratory comparison of the CD-1 neonatal mouse logistic dose-response model for Cryptosporidium parvum oocysts.

cryptosporidium parvum oocyst viability can be determined by vital dyes, in vitro excystation, and cell culture; however, neonatal mouse infectivity assays are the reference method. Unfortunately, there have been few efforts to standardize methods for infectivity assays thus casting a veil of uncertainty over the significance and comparability of results. In order to address this issue, two laboratories proficient in measuring oocyst infectivity conducted independent dose titration studies with neonatal CD-1 mice using standardized protocols and a well-characterized isolate of Cryptosporidium parvum. The resulting independent logistic dose-response models derived by regression analysis were compared with each other and with a published model. The comparisons showed these dose-response functions to be reproducible under standardized conditions. It is important to standardize mouse strain, age of mice at inoculation and necropsy, oocyst isolate, and age of oocysts. However, other factors, including methods used to detect infectivity and to count oocyst doses, appear less critical. Adopting a standardized assay for oocyst infectivity will provide both a basis for comparing data from various oocyst disinfection studies and a suitable platform for evaluating new or existing in vitro viability surrogates such as excystation, vital dyes or cell culture.

Identification and healing of leg ulcers with impaired circulation.

Leg ulcers may fail to heal because inaccurate assessment has resulted in inappropriate treatment. This article suggests a more accurate method of assessment and describes the use of zinc oxide paste bandage to heal leg ulcers where there is impaired arterial circulation.
