Decision In the Matter of Gray highlights complications that advancing medical technology causes to the law - case concerns the issue of removal of semen from a deceased man - how the courts deal with matters concerning medical technology in the absence of specific legislation or established case law - legal and moral questions raised by the case.

Outcome of the acute abdomen in patients with previous spinal cord injury

Background: Patients with spinal cord injury (SCI) have always posed difficulties for the diagnosis of an acute abdomen. The aim of the present study was to define this problem retrospectively at Princess Alexandra Hospital and to assess the results of treatment for these patients. Methods: A retrospective review was conducted of 133 SCI patients admitted with an acute abdomen in the 16 years prior to this analysis at the Spinal Injuries Unit (SIU) of Princess Alexandra Hospital. There were 21 patients who conformed to the study criteria. All the patients had sustained traumatic SCI at or above the level of T11, more than 1 month prior to admission. Results: There were 13 male and eight female patients. The time lapse between SCI and the onset of an acute abdomen ranged from 1.5 months to 27 years. The age range was 26-79 years. The majority of patients had C6 injuries (six patients). There were 18 patients with injury levels above T6 and three patients with injuries below this level. The time taken to diagnose the cause of the acute abdomen ranged between 1 day and 3 months. Investigations were found to be useful in making the diagnoses in 61.9% of cases. There were 14 patients who had surgical interventions. Five patients had surgical complications and there were two deaths in the study. The length of follow up was 1-132 months. The mortality in the study was 9.5%. Conclusion: An aggressive approach to the diagnosis and treatment of the acute abdomen in SCI patients with suspicious symptoms is recommended. A high index of suspicion should be maintained in those patients with pre-existing SCI who present with abdominal trauma.

Single institution outcomes of treatment of severe aplastic anaemia

Background: In severe aplastic anaemia, the treatment of choice for young patients with a human leucocyte antigen-matched sibling is now established as allogeneic bone marrow transplantation (BMT). In older patients and in those without a matched sibling donor, immunosuppressive therapy is the usual first option. 'Alternative' marrow donors are emerging as an option for those without a matched sibling donor. Aims: To review 10 years of local experience in treating severe aplastic anaemia with BMT and immunosuppressive therapy with emphasis on long-term outcomes. Methods: A retrospective analysis was performed of all patients with severe aplastic anaemia presenting to the Royal Brisbane and Royal Children's Hos- pitals between 1989 and 1999. Data were abstracted regarding patient demographics, pretreatment characteristics and outcome measures, including response rates, overall survival and long-term complications. Results: Twenty-seven consecutive patients were identified, 12 treated with immunosuppression alone and 15 with BMT. In these two groups, transfusion independence was attained in 25% and 100%, respectively, with overall survival being 36% and 100%, respectively. Those treated with immunosuppression were significantly older (median 41.5 versus 22 years, P = 0.008). Long-term survivors of either treatment had extremely low morbidity. Three patients carried pregnancies to term post-transplant. Three patients received alternative donor BMT with correspondingly excellent survival. Conclusions: Patients treated with allogeneic BMT for severe aplastic anaemia enjoyed extremely good long-term survival and minimal morbidity. Patients treated with immunosuppressive therapy had a poorer outcome reflecting their older age and different usage of therapies over the past decade. Optimal treatment strategies for severe aplastic anaemia remain to be determined.

Combination therapy with tacrolimus and anti-thymocyte globulin for the treatment of steroid-resistant acute graft-versus-host disease developing during cyclosporine prophylaxis

We report our experience with the combination of anti-thymocyte globulin (ATGAM) and tacrolimus in the treatment of 20 patients with steroid refractory and dependent acute graft-versus-host disease (GVHD) transplanted between August 1996 and February 2000. All patients received cyclosporine-based GVHD prophylaxis. Thirteen patients developed a maximum of grade TV, five grade III and two grade II acute GVHD, with 15 patients being refractory to steroids and five dependent on steroids. Patients were treated with ATGAM (15 mg/kg for 5 d) and tacrolimus (0.025-0.1 mg/kg/d) in addition to continuation of their high-dose steroids and cessation of their cyclosporine. Within 28 d of treatment, we observed eight complete responses (CR), six partial responses (PR) and six with no response. Overall response (CR + PR) was predicted by GVHD severity. Infectious complications occurred in 80% of patients. The median survival was 86.5 d (range, 21-1081 d) with 35% of patients remaining alive, Survival following combination therapy was significantly more likely in men (P < 0.001), skin-only GVHD (P = 0.027), less severe GVHD (P = 0.048), and in responders to tacrolimus and ATGAM (P< 0.001). In conclusion, concurrent introduction of ATGAM and tacrolimus is a promising therapeutic combination for GVHD refractory to steroids and cyclosporine.

Early toxicity from preoperative radiotherapy with continuous infusion 5-fluorouracil for resectable adenocarcinoma of the rectum: A phase II trial for the Trans-Tasman Radiation Oncology Group

Purpose: To assess the toxicity and the efficacy of preoperative radiotherapy with continuous infusion 5-fluorouracil (5-FU) for locally advanced adenocarcinoma of the rectum. Methods and Materials: Eligible patients had newly diagnosed localized adenocarcinoma of the rectum within 12 cm of the anal verge, Stage T3-4, and were suitable for curative resection. Eighty-two patients were treated with radiotherapy-50.4 Gy in 28 fractions in 5.6 weeks, given concurrently with continuous infusion 5-FU, using either 96-h/week infusion at 300 mg/m(2)/day or 7-days/week infusion at 225 mg/m(2)/day. Results: The median age was 59 years (range, 27-87), and 67% of patients were male. Pretreatment stages of the rectal cancer were T3, 89% and resectable T4, 11%, with endorectal ultrasound confirmation in 67% of patients. Grade 3 acute toxicity occurred in 5 of 82 patients (6%; 95% confidence interval [CI], 2-14%). Types of surgical resection were anterior resection, 61%; abdominoperineal resection, 35%; and other procedures, 4%. There was no operative mortality. Anastomotic leakage after low anterior resection occurred in 3 of 50 patients (6%; 95% CI, 1-17%). The pathologic complete response rate was 16% (95% CI, 9-26%). Pathologic Stages T2 or less occurred in 51%. Conclusion: Preoperative radiotherapy with continuous infusion 5-FU for locally advanced rectal cancer is a safe regimen, with a significant downstaging effect. It does not seem to lead to a significant increase in serious surgical complications. (C) 2001 Elsevier Science Inc.

Safety and efficacy of low anterior en bloc resection as part of cytoreductive surgery for patients with ovarian cancer

Objective. To examine the feasibility and safety of a low anterior resection of the rectosigmoid plus adjacent pelvic tumour as part of primary cytoreduction for ovarian cancer. Methods. This study included 65 consecutive patients with primary ovarian cancer who had debulking surgery from 1996 through 2000. All patients underwent an en bloc resection of ovarian cancer and a rectosigmoid resection followed by an end-to-end anastomosis. Parameters for safety and efficacy were considered as primary statistical endpoints for the aim of this analysis. Results. Postoperative residual tumour was nil, 1 cm in 14, 34, and 14 patients, respectively. The median postoperative hospital stay was 11 days (range, 6 to 50 days). Intraoperative complications included an injury to the urinary bladder in one patient. Postoperative complications included wound complications (n=14, 21.5%), septicemia (n=9, 13.8%), cardiac complications (n=7, 10.8%), thromboembolic complications (n=5, 7.7%) ileus (n=2, 3.1%) anastomotic leak (n=2, 3.1%) and fistula (n=1, 1.5%). Reasons for a reoperation during the same admission included repair of an anastomotic leak (n=1), postoperative hemorrhage (n=1), and wound debridement (n=1). Wound complications, septicemia, and anastomotic leak formation were more frequent in patients who had a serum albumin level of less than or equal to 30 g/L preoperatively. There was one surgically related mortality in a patient who died from a cerebral vascular accident 2 days postoperatively. Conclusions. An en bloc resection as part of primary cytoreductive surgery for ovarian cancer is effective and its morbidity is acceptably low. (C) 2001 Academic Press.

Targets to trials in diabetic complications

Diabetes is now the leading cause of end-stage renal disease, blindness, lower-extremity amputations and impotence. In addition, the risk of death from cardiovascular disease such as myocardial infarction and stroke is more than doubled in diabetics. In September 2001, scientists from around the world met in Melbourne to discuss the mechanisms underlying neuronal and vascular changes in diabetic complications. This report summarizes the meeting and attempts to identify potential targets for drug intervention in diabetic complications. (C) 2001 Prous Science. All rights reserved.

Outcome of stroke patients admitted to intensive care: Experience from an Australian teaching hospital

The objective of this study was to determine the mortality rate and the functional outcomes of stroke patients admitted to the intensive care unit (ICU) and to identify predictors of poor outcome in this population. The records of all patients admitted to the ICU with the diagnosis of stroke between January 1994 and December 1999 were reviewed. Patients with subarachnoid haemorrhage were excluded. Data were collected on clinical and biological variables, risk factors for stroke and the presence of comorbidities. Mortality (ICU, in-hospital and three-month) and functional outcome were used as end-points. In the six-year-period, 61 patients were admitted to the ICU with either haemorrhagic or ischaemic stroke. Medical records were available for only 58 patients. There were 23 ischaemic and 35 haemorrhagic strokes. The ICU, in-hospital and three-month mortality rates were 36%, 47% and 52% respectively. There were no significant differences in the prevalence of premorbid risk factors between survivors and non-survivors. The mean Barthel score was significantly different between the independent and dependent survivors (94 +/- 6 vs 45 +/- 26, P < 0.001). A substantial number of patients with good functional outcomes had lower Rankin scores (92% vs 11%, P < 0.001). Only 46% of those who were alive at three months were functionally independent. Intensive care admission was associated with a high mortality rate and a high likelihood of dependent lifestyle after hospital discharge. Haemorrhagic stroke, fixed dilated pupil(s) and GCS < 10 during assessment were associated with increased mortality and poor functional outcome.

Survival following mechanical ventilation of recipients of bone marrow transplants and peripheral blood stem cell transplants

Survival of bone marrow transplant recipients requiting mechanical ventilation is poor but improving. This study reports a retrospective audit of all haematopoietic stem cell transplant (HSCT) recipients requiring mechanical ventilation at an Australian institution over a period spanning 11 years from 1988 to 1998. Recipients of autologous transplants are significantly less likely to require mechanical ventilation than recipients of allogeneic transplants. Of 50 patients requiring mechanical ventilation, 28% survived to discharge from the intensive care unit, 20% to 30 days post-ventilation, 18% to discharge from hospital and 12% to six months post-ventilation. Risk factors for mortality in the HSCT recipient requiting mechanical ventilation include renal, hepatic and cardiovascular insufficiency and greater severity of illness. Mechanical ventilation of HSCT recipients should not be regarded as futile therapy.

Iatrogenic bile duct injury: The scourge of laparoscopic cholecystectomy

Background: Laparoscopic cholecystectomy (LC) has become the first-line surgical treatment of calculous gall-bladder disease and the benefits over open cholecystectomy are well known. In the early years of LC, the higher rate of bile duct injuries compared with open cholecystectomy was believed to be due to the 'learning curve' and would dissipate with increased experience. The purpose of the present paper was to review a tertiary referral unit's experience of bile duct injuries induced by LC. Methods: A retrospective analysis was performed on all patients referred for management of an iatrogenic bile duct injury from 1981 to 2000. For injuries sustained at LC, details of time between LC and recognition of the injury, time from injury to definitive repair, type of injury, use of intraoperative cholangiography (IOC), definitive repair and postoperative outcome were recorded. The type of injury sustained at open cholecystectomy was similarly classified to allow the severity of injury to be compared. Results: There were 131 patients referred for management of an iatrogenic bile duct injury that occurred at open cholecystectomy (n = 62), liver resection (n = 5) and at LC (n = 64). Only 39% of bile duct injuries were recognized at the time of LC. Following conversion to open operation, half the subsequent procedures were considered inappropriate. When the injury was not recognized during LC, 70% of patients developed bile leak/peritonitis, almost half of whom were referred, whereas the rest underwent a variety of operative procedures by the referring surgeon. The remainder developed jaundice or abnormal liver function tests and cholangitis. An IOC was performed in 43% of cases, but failed to identify an injury in two-thirds of patients. The bile duct injuries that occurred at LC were of greater severity than with open cholecystectomy. Following definitive repair, there was one death (1.6%). Ninety-two per cent of patients had an uncomplicated recovery and there was one late stricture requiring surgical revision. Conclusions: The early prediction that the rate of injury during LC would decline substantially with increased experience has not been fulfilled. Bile duct injury that occurs at LC is of greater severity than with open cholecystectomy. Bile duct injury is recognized during LC in less than half the cases. Evidence is accruing that the use of cholangiography reduces the risk and severity of injury and, when correctly interpreted, increases the chance of recognition of bile duct injury during the procedure. Prevention is the key but, should an injury occur, referral to a specialist in biliary reconstructive surgery is indicated.

Differences in lung function, growth parameters and frequency of hospital admissions between adolescents with cystic fibrosis-related diabetes and controls

As survival of patients with CF increases,glucose intolerance and cystic fibrosisrelated diabetes (CFRD),ar e increasingly recognised common complications. CFRD may be preceded by a pre-diabetic state. Using markers identified as being associated with CFRD may improve targeted screening. Aim: To identify features consistently predicting CFRD in paediatric patients. Patients diagnosed with CFRD between January 1997–January 2002 were compared with age and sex matched controls. Clinical,micr obiological, and hospitalisation data was collected at time of CFRD diagnosis,and at six monthly intervals for 3 yr prior to diagnosis. Eight patients with CFRD were identified,mean age 13.7 yr (S.D. 3.49) at time of diagnosis. Control patients underwent OGTT to ensure normal glucose tolerance. Patients with CFRD had a lower FEV1 up to 12 months prior to diagnosis however, this was only significant at diagnosis. There was no difference in weight and height z scores between the 2 groups; however,the decrease in weight and height z scores in the CFRD group over 3 yr prior to diagnosis was significant. Mean number of days in hospital and admissions per patient significantly increased in the CFRD group,6 months prior to diagnosis. No other significant differences were observed between the 2 groups. Conclusions: This study has shown a difference in lung function,gr owth parameters and frequency of hospital admissions between patients with CFRD and controls. These differences may be utilised as tools for targeted screening in the paediatricyadolescent population. Further larger scale studies are required to improve guidelines for targeted screening in this population.
