Major trauma in Australia: a regional analysis

Abstract: This study was undertaken to evaluate the frequency, distribution, cause, pattern, and outcome of patients suffering from major trauma in the State of Victoria over a 1-year period. No previous study in Australia has attempted a comprehensive regional analysis of major trauma. All major trauma admissions resulting from blunt, penetrating, and burns injury were identified, and data collected from emergency departments and intensive care log books at 25 major metropolitan and rural hospitals from the January 3, 1992 to February 28, 1993 by onsite data collectors. The total number of patients admitted into the study was 2,944. There were 1,076 major trauma cases with an Injury Severity Score greater than 15 in a population of 4.2 million people. The type of injury was predominantly blunt (87.5%), with only a small percentage of penetrating injuries (6.4%) and burns (6%). Major trauma in pediatric cases is less common (132 cases). The most common causes of injury were road transport (56%) and falls (22%). The overall outcome of the group was favorable when compared with the Major Trauma Outcome Study group (Z = 1.4, M = 0.93, W = 0.52). There was an unexpectedly low number of patients suffering from major trauma. Outcome using Trauma and Injury Severity Score methodology was favorable when compared with North America.

Imaging wool fiber surfaces with a scanning force microscope

Abstract: Surfaces of wool scales are imaged using a scanning force microscope (SFM) and a field emission scanning electron microscope (FESEM). Atomic force microscope (AFM) images of wool fiber surfaces can be correlated with FESEM micrographs to provide complementary views of surface features. The AFM images are analyzed for scale height; on average there is a 21% increase when changing from air to water. The variability of scale height changes is large, and a model involving both swelling and scale move ment has been proposed. Lateral force microscope (LFM) images show complementary information to topographic AFM images and reveal the effects of surface treatment not available with other imaging techniques. Such images of treated wool surfaces reveal major inhomogeneities in friction, which are interpreted as differences in chem ical composition.

The Basolan AS process: a new concept in wool dyeing

Abstract: The new Basolan AS process for wool dyeing is described. The process restricts the deterioration of wool properties that occurs as a result of dyeing. This is achieved through a reduction in the extent to which wool is permanently set during dyeing. Two options are available to the dyer involving the addition of antisetting chemicals to the wool dyebath. Processing and product benefits can be obtained for wool dyed as loose fibre, top, yarn (package or hank) and woven fabric.

Necrotising arachnidism treated with hyperbaric oxygen.

Abstract: required painful daily dressing changes, made tolerable through the use a 50:50 mixture of nitrous oxide and oxygen which he inhaled through a mask. Over seven months the patient was exposed daily to this gas and underwent multiple administrations of nitrous oxide general anaesthesia for prolonged orthopaedic procedures. After the last operation, which lasted four hours, the patient developed intermittent drowsiness and confusion that was exacerbated by further use of the nitrous oxide/oxygen gas. He complained of paraesthesiae in the legs, an \"electric shock\" sensation with flexion of the neck (Lhermitte's sign) and he was unable to stand unassisted. Examination revealed generalised hyperreflexia, increased tone in the lower limbs and extensor plantar responses, bilateral foot drop and weakness of the intrinsic hand muscles, and distal reduction of proprioception and vibration sense signs of myeloneuropathy indistinguishable from classical subacute combined degeneration of the cord due to vitamin BI2 deficiency. Preoperative haematological test results were normal but postoperative results showed leucopenia at 1.1 X 109/L (normal range, 4.0-10.5 x 109/L) and severe neutropenia at 0.1 x 10 9/L (normal range, 1.9-6.8 X 109/L). Serum and red cell folate levels were normal, but his vitamin BI 2 level was < 40 pmollL (normal range, 130660 pmol/L) and his bone marrow showed megaloblastic changes. There was no evidence of dietary deficiency of vitamin BI2 or of malabsorption. Pernicious anaemia was excluded by the absence of intrinsic factor antibodies and a subsequent Schilling test was normal. Nerve conduction studies revealed absent sensory and motor potentials in the lower limbs and normal values in the upper limbs. Needle electromyogram revealed profuse denervation potentials in muscles below the knees. Computed tomography showed widened cerebral sulci and enlarged ventricles. Magnetic resonance imaging showed an abnormal signal within the spinal cord. The neurological and haematological findings were attributed to vitamin BI 2 deficiency induced by chronic exposure to nitrous oxide. Use of the nitrous oxide/oxygen gas was stopped and daily replacement of vitamin BI 2 was commenced. The patient's encephalopathy cleared within 10 days and there was steady improvement in his general neurological status. Twelve months later, all neurological abnormalities had resolved and a repeat brain computed tomography scan was normal. Normal haematological and vitamin BI 2 results have been reported in published cases of nitrous oxide neurctoxicity-\" and therefore do not exclude the diagnosis. Clinicians should be aware of the potential danger of repeated exposure to nitrous oxide in hospitalised patients.

Streptococcal septic vasculitis

Abstract: A case of invasive streptococcal disease is presented. Bacteraemic spread from a peritonsillar abscess produced acral purpuric plaques that blistered and ulcerated. Histology showed a vasculitic picture. Group A beta-haemolytic Streptococcus was cultured from the skin biopsy and seen on Gram stain.

An Automated Color-Sorting Device for Wool and Other Fibers

Abstract: A new method is described for on-line sorting of colored faults from undyed fibrous materials such as scoured or carbonized wool. To obtain realistic throughput rates, the wool is pneumatically conveyed in sorting ducts at air speeds of 16 m/s and the faults selectively removed by a high-speed reject device. A prototype six-duct sorter having a designed capacity of 1000 kg/h is tested on both wool and cotton. The sorting performance of the device with carbonized wool is a large improvement over existing manual sorting procedures, with reject rates of up to five faults per second per duct. Trials are also described in which stains and matted clumps are removed from top- making wools. In addition, sorting manmade contaminants from wool and cotton proves to be both efficient and selective.

Phototherapy burns and fluoxetine.

Abstract: A 43 year old woman with chronic plaque psoriasis was undergoing therapy with narrow band UVB. After 3 weeks of treatment she was seen to be improving. She had achieved a time of 5 min and this dose was repeated after 2 days. The accuracy ofthe setting was confirmed both by the operator and the patient. One hour after the second treatment at 5 min, she developed marked facial erythema and after 6 hours she had a painful generalized erythema and blisters on her neck. She was treated with rest, oral prednisolone, topical aloe vera gel and betamethasone diproprionate cream. The following day the patient reported blistering on her arms in the sites where she had previous psoriasis. She slowly improved but with considerable discomfort over the next week. The patient denied any extra sun exposure but in the 48 hours prior to the UV treatment she admitted to taking oxycodone, dextropropoxyphene and fluoxetine. A literature search [Medline (1994-1988) and the International Pharmaceutical Abstracts] failed to reveal any reports of photosensitivity with these agents but the Australian Adverse Drug Reaction Committee had reviewed two case reports of a possible photosensitivity with fluoxetine. Burning may occur more readily with narrow band UVB than with broad band UVB as a steeper erythema-dose curve has been reported with narrow band tubes.' Blistering limited to areas where psoriasis has been present has also been reported with narrow band UVB.̂ The role of a possible photosensitizing drug in this case could not be proved but no other explanation could be offered for the severe burn at a dose of UVB well tolerated 3 days before. This case highlights the importance of a drug history in patients undergoing phototherapy.

Analysis of Crosslinked Silicones on Wool by Atomic Absorption Spectroscopy

Abstract: A simple method has been devised for the quantitative analysis of crosslinked silicones on wool. The advantages of this method are its insensitivity to the presence of silica or silicates and its ability to detect concentrations less than 0.1% silicone solids on the mass of wool. The method involves depolymerization of the cured silicone by aminolysis with anhydrous n-propylamine. The solubilized silicone is then extracted into methylisobutylketone and the silicon content determined by atomic absorption spectroscopy. The method has been tested with two commercial amino functional organosiloxanes currently used in finishing wool fabrics.

Response to Letters from Peet et al. and Zahn et al

Abstract: We accept the assignment by Peet et al. [ 1 ] that the 341 mass peak in the negative ion SSIMS of wool fibers ~ may be a sulfur containing species [2], but we were reluctant to postulate this in our original paper [ 3 ] due to the lack of lower molecular weight sulfur containing species such as RSO-. However, we cannot accept their proposal that the mass 325 peak arises from free hydrolyzed C2, fatty acid on the surface. We feel that any free acids on the surface of our samples would not survive the repeated solvent extraction and prolonged evacuation under very low pressure before SSIMS were determined. Clearly high resolution SSIMS will confirm these peak assignments. The main point we wish to ; highlight is that our SSIMS data provide unequivocal direct evidence of surface covalently bound C2, lipid on wool. With regard to our estimate of the thickness of the lipid layer, one must realize that there is a significant relative error, since a number of assumptions were ’ made, including the idea that the lipid was present as a continuous film. It is not realistic to relate the thick-

Knowledge acquisition for reactive scheduling

Abstract: In this paper we report on the development and use of a tool for the acquisition of heuristics used by operators of a glass coater in reactive scheduling. These results complement previous studies of neural network process models in scheduling production for the glass coating operation (AIRCO) at Pilkington Australia. Integration of our knowledge rich control strategies in the construction of an Expert Adviser for scheduling is now in progress.

Probable chloracne with the use of a cow udder ointment.

Abstract: A 55 year old lady presented with a 6 month history of an itchy eruption on her scalp, face and arms. The appearance was eczematous with areas of probable lichenification; however, it was somewhat atypical and therefore biopsies were taken. The specimen from the arm showed epidermal spongiosis while that from the back showed a dilated follicular structure containing plasmatic material and many neutrophils. The epithelium was spongiotic. The eruption responded to topical and oral steroids to some degree but the patient subsequently developed burning (not itching), well demarcated erythematous plaques on her cheeks. She was patch tested negative and because she had a history of
