SummaryThe accurate detection and localisation of retained intraocular foreign bodies (IOFB) is important in the planning of subsequent surgical management. Using a porcine eye model, the authors have compared the relative detection rates of real time ultrasonography and plain roentgenograms for a variety of IOFBs. With an overall detection rate of 93%, ultrasonography appears to be a considerably more sensitive investigative tool than plain roentgenograms (40%) for the imaging of IOFBs, particularly those that are non-metallic.Ocular trauma remains the most common indication for enucleation in the young popu lation and the presence or absence of an intra ocular foreign body (IOFB) significantly affects the management of eyes that might be salvaged.

SummaryThirty healthy patients were randomised to receive either a single bolus dose of rocuronium 0.6 mg.kg-' or vecuronium 0.1 mg.kg-' during halothane anaesthesia. Onset time, duration 25, duration 75 and train-offour 70 were measured. The onset of neuromuscular blockade following rocuronium was more rapid than vecuronium ( p = 0.0001). AN other pharmacodynamic parameters were similar. During the first minute following injection of the neuromuscular blocking agent, the heart rate increased by 36% in the rocuronium group but remained stable in those patients who received vecuronium (p = 0.oooS). No adverse effects were noted in either group.

Metastatic disease to the breast from extra mammary sites is uncommon and has an incidence of 0.5 to 3%. It is important to make an accurate diagnosis as this has an impact on the therapeutic planning and management. Clinically, it can be difficult to differentiate between primary breast cancer and a metastatic disease. An incorrect diagnosis can lead to unnecessary surgical interventions. Immunohistochemistry has a significant role in identifying the primary origin of tumor and has to be considered in the presence of unusual cytologic patterns. We report three cases of metastatic disease to breast from primary lung tumors. The cases demonstrate the difficulties encountered in the diagnosis and the impact on the management of these patients.

Background Bisphosphonates have been shown to be effective agents in the treatment of postmenopausal osteoporosis.Because corticosteroid associated osteoporosis is often associated with increased bone turnover, the effect of intermittent intravenous infusions of pamidronate on this condition has been investigated. Methods Seventeen patients (five male) with chronic corticosteroid dependent lung disease (15 asthma, two sarcoidosis) were treated with infusions of 30 mg pamidronate once every three months for one year. These patients had been taking an average of 14 (range 7-5-40) mg prednisolone a day for an average of 14 (range 3-30) years. Bone density measurements, by dual energy x ray absorptiometry, and radiography of the dorsolumbar spine were carried out before and one year after treatment. Bone formation was assessed by measurement of serum alkaline phosphatase and bone resorption by measurement of the fasting urinary hydroxyproline : creatinine ratio at the same time as densitometry and radiography were performed. Results Pretreatment density of L2-4 and the neck of the femur was significantly lower in these patients compared with a cohort of 100 age and sex matched controls (L2-4 (mean (SEM)): 0-906 (0 050) g/ cm2 v 1-142 (0-016) glcm2; neck of femur: 0 793 (0 030) glcm2 v 0-936 (0-013)) glcm2.After treatment there was a significant fall in serum alkaline phosphatase activity from (mean (SEM)) 220 (16) UII to 174 (9) U/l (normal 80-280 Ul1) and in the fasting urinary hydroxyproline:creatinine ratio from (mean (SEM) 0-040 (0-006) to 0-024 (0-003) (normal <0-033). A significant rise was noted in L2-4 density to 0-927 (0 047) g/ cm2; mean rise of 3-4%). No change was noted in density of the neck of the femur. Conclusions Intermittent infusions of intravenous pamidronate would seem to be effective in both reducing turnover of bone and increasing bone density in corticosteroid induced osteoporosis associated with chronic lung disease. Longer term controlled studies are indicated. (Thorax 1992;47:932-936)

There is a further significant reduction in both uterine volume and dominant fibroid diameter between 6 months and 5 years after UAE. Complete fibroid infarction does not translate into total freedom from a subsequent reintervention. New fibroid formation is significantly higher after myomectomy.

SummaryIncreasing numbers of patients presenting for surgery are receiving concurrent medication with low-dose aspirin. We surveyed the opinions and working practices of consultant members of the Neuroanaesthesia Society regarding patients who present for elective intracranial surgery whilst taking this form of medication. Identical questionnaires were sent to 140 members of the society and proffered four main questions: (1) the adherence to any policy of stopping aspirin preoperatively, (2) the preferred method of treatment for excessive bleeding in this context, (3) personal knowledge of haemorrhagic complications in this group of patients, (4) the neurosurgical unit concerned. There were 121 responses (86.4%) of which 116 (82.9%) were valid. Of the respondents, 78 (67.2%) were unaware of a written departmental policy for the discontinuation of pre-operative aspirin treatment and had no personal policy. Thirty-two respondents (27.6%) had a personal policy but were unaware of a written departmental policy; only six respondents (5.2%) stated that a written departmental policy was in place. The mean time suggested for discontinuation of aspirin pre-operatively was 11.3 days (range: 1-42 days). Fifty-one respondents (44.0%) considered that patients taking low-dose aspirin were at increased risk of excessive perioperative haemorrhage and 15 (12.9%) anaesthetists reported having personal experience of such problems. Fifty-seven respondents (49.1%) would use a platelet infusion, alone or in association with other blood products or prohaemostatic agents, if haemorrhagic complications developed. The majority of neuroanaesthetists felt that aspirin was a risk factor for haemorrhagic complications associated with intracranial procedures, but most adopt no policy regarding its preoperative discontinuation.Keywords Surgery; neurosurgical.

Accepted: 18 October 1996 Aspirin is increasingly prescribed for its antithrombotic properties [1][2][3][4][5] and more patients are therefore presenting for surgery with dysfunctional circulating platelets. Aspirin is also a common constituent of many 'over the counter ' medications [6].The contribution of low-dose aspirin to increased perioperative blood loss is a contentious issue with conflicting published results from different surgical groups. Data from neurosurgical patients are sparse [7] but aspirin has been identified as an important risk factor in the development of postoperative haematomata following intracranial surgery [8].This survey examined the opinions and working practices of consultant neuroanaesthetists with regard to patients taking low-dose aspirin medication who present for elective intracranial surgery. MethodsIdentical questionnaires with stamped addressed return envelopes were sent to practising consultant members o...

SummaryMany surgical patients are anxious while waiting to go to the operating theatre in spite of the best preparation with drugs, information and reassurance. It is possible that patients could be more comfortable if allowed a choice of activities before operations. The objective of this study was to find out how pre-operative patients might prefer to occupy their time. We distributed 200 questionnaires to elective surgery patients and 184 (92%) were available for analysis. Of the respondents, 54.1% wanted to be slightly sleepy, 72.0% preferred not to be fast asleep and 57.2% preferred not to be wide awake. Reading (56.8%), listening to music (57.1%) and chatting with other patients (39.9%) were preferred activities. It might be appropriate to ask patients how sedated they would wish to be before their surgery and perhaps have alternatives to sedation available.
