Mutilating meat mincer injuries of the hand.

A total of 25 cases of acute injuries caused by a meat mincer are presented. Of these, 20 were children. The pattern of injury and the extent of damage to individual digits of the hand are defined. Due to the mutilating nature of the injury, attempts at replantation or revascularization failed in all but two of the ischaemic digits. Emphasis must be placed on the safety and prevention of these dreadful accidents.

Recovery of potential pathogens from feeding bottle contents and teats in Zaria, Nigeria.

Pathogens were recovered from the contents of 41 out of 50 feeding bottles and from 32 teats in a survey in Zaria, Nigeria. 39 bottle contents and 30 teats yielded enteric pathogens. Traditional weaning gruels were more contaminated than were commercial feeds. Koko bottles yielded more pathogens than Akamu bottles. Enteropathogenic Escherichia coli was the most common pathogen recovered, seen more in bottle contents than teats. Bottle hygiene was poor and cleaning methods and feeding practices were not satisfactory. Lack of facilities in the home prevented better hygiene. Prolonged pre-cooking preparation, storage of gruels in bulk for the whole day in thermos flasks or enamel bowls, and inadequate hygiene in the preparation of commercial feeds resulted in the large recovery of pathogens. Alternate feeding methods were suggested and the need for the practice of good hygiene by all who are involved in the preparation of infant feeds was emphasized.

Accidental contamination from uranium compounds through contact with ceramic dinnerware.

Examination of orange-colored dinnerware samples purchased in antique stores and flea markets has revealed the occasional presence of surface uranium compounds that are readily transferred to the hands and clothing. We have further been able to produce soluble uranium compounds on the surfaces of clean dishes by exposing them to household vinegar or bleach. We estimate that handling of a contaminated dish can transfer up to 1-2 becquerels or more of uranium compounds to the hands. Uranium contamination is of concern because the element is not only an alpha emitter but also a chemical nephrotoxin. Although the amount of uranium likely to be ingested as a result of casual handling may be small, it could still exceed by several times the amount occurring in the average diet (about 40 mBq/day). Furthermore, since fresh surface compounds are readily formed, it is possible that a person who regularly handles or eats from uranium-glazed dinnerware can accidentally ingest significant amounts of uranium.

Effect of microwave heating on leaching of lead from old ceramic dinnerware.

When samples of pre-1950s U.S.-made ceramic dinnerware, purchased in antique shops and flea markets, were filled with 4% acetic acid or 0.5% citric acid and heated in a microwave oven for 2-5 min, lead was leached in amounts of up to 5 mg per dish. Concentrations of lead in the leachates were not significantly correlated with, and could not be predicted from, concentrations in leachates measured during 24-h room temperature acid leaching tests. Unsafe lead concentrations (>3 microg/ ml) were found in microwave leachates of dishes with uranium-containing glazes, with copper-containing glazes, and with floral over-the-glaze decals. This evidence suggests that use of such dishes to microwave common foods could result in the ingestion of dangerously large amounts of lead.

Microwave: practical cost-effective method for sterilizing urinary catheters in the home.

We used a standard microwave oven to sterilize red rubber catheters used for intermittent self-catheterization. Catheters were incubated for sixty minutes in a suspension of microorganisms isolated from the urine of patients with urinary tract infections. For each trial, 6 catheters were removed from their respective suspensions, placed in separate plastic freezer bags, distributed evenly in a microwave oven (avoiding cold spots), and microwaved simultaneously for twelve minutes. A control catheter was not microwaved. Two strains of each microorganism were tested. The urinary isolates were Escherichia coli, Klebsiella sp., Proteus sp., Enterobacter sp., Pseudomonas sp., Streptococcus sp., Staphylococcus sp., and Candida sp. In each experiment, all 6 catheters were sterilized. Repeat sterilization in the microwave oven did not affect the integrity of the catheters or the plastic bags. A water heat sink of constant volume was employed. A home microwave oven may be used as a method to sterilize red rubber catheters for reuse with a recommended time of twelve minutes at full power. This technique makes aseptic intermittent self-catheterization a practical possibility.

Palatal trauma: an unusual cause of a parotid sinus.

A case is described of a 3-year-old boy who presented with a seemingly trivial injury to his soft palate, who went on to develop a parotid sinus as a result of a retained foreign body. This is a rare clinical problem and it highlights the difficulty in the clinical assessment of a palatal injury--especially in children. The child had the foreign body removed successfully 5 months after the initial injury and made an uneventful recovery.

Clear plastic cups: a childhood choking hazard.

The disposable plastic beverage cup is not usually regarded as hazardous to young children. Certain varieties of these products however, are manufactured from a brittle, clear plastic that easily cracks and fragments. While most conscientious parents keep their children safe from peanuts, balloons, and other known choking hazards, a child can surreptitiously bite a cup edge and aspirate the fragment. We report two cases of foreign body aspiration involving clear plastic cups that went undetected one of which remained 21 months following a negative rigid bronchoscopy. Diagnostic difficulties are related to the transparency and radiolucency of these objects. When suspicious of foreign body aspiration in children, otolaryngologists should inquire about the availability of clear plastic cups in the household and be mindful of the diagnostic pitfalls. Further investigations including CT scanning and repeat bronchoscopy may be helpful in cases of suspected missed foreign bodies. An educational campaign aimed at prevention and placement of product package warning labels should be established.

Small dishwashers for hospital ward kitchens.

A comparison of the cleaning efficiency and thermal disinfection capabilities of 12 small dishwashers being used in hospital wards was carried out. Machines installed prior to the establishment of a local purchase policy failed to achieve the standards required for hygienic washing up. Machines conforming to the purchasing criteria gave a satisfactory performance.

The prophylactic reduction of aluminium intake.

The use of modern analytical methods has demonstrated that aluminium salts can be absorbed from the gut and concentrated in various human tissues, including bone, the parathyroids and brain. The neurotoxicity of aluminium has been extensively characterized in rabbits and cats, and high concentrations of aluminium have been detected in the brain tissue of patients with Alzheimer's disease. Various reports have suggested that high aluminium intakes may be harmful to some patients with bone disease or renal impairment. Fatal aluminium-induced neuropathies have been reported in patients on renal dialysis. Since there are no demonstrable consequences of aluminium deprivation, the prophylactic reduction of aluminium intake by many patients would appear prudent. In this report, the major sources of aluminium in foods and non-prescription drugs are summarized and alternative products are described. The most common foods that contain substantial amounts of aluminium-containing additives include some processed cheeses, baking powders, cake mixes, frozen doughs, pancake mixes, self-raising flours and pickled vegetables. The aluminium-containing non-prescription drugs include some antacids, buffered aspirins, antidiarrhoeal products, douches and haemorrhoidal medications. The advisability of recommending a low aluminium diet for geriatric patients is discussed in detail.

Aluminium coffee percolators as a source of dietary aluminium.

The aluminium content of coffee brewed and stored in aluminium percolators was measured using atomic absorption spectrometry. Brewing in a new aluminium pot added 0.88 (immediately after brewing ) to 1.18 mg aluminium (after a further 12-hr storage in the pot and reheating ) to each cup of coffee. Percolators which had been used repeatedly were less susceptible to mobilization of aluminium by coffee, and brewing in these increased the aluminium content of each cup of coffee by 0.40 mg immediately after brewing and by 0.58 mg after storage for 12 hr in the pot and reheating . The aluminium content of the ground coffee beans used in this work was relatively high (51.8 ppm). To demonstrate that the bulk of the aluminium measured in the percolated coffee samples were dissolved aluminium and was not part of the aluminium associated with the ground coffee, the dialysable aluminium was measured in some samples of coffee percolated in a new aluminium pot. These data indicate that 61% of the aluminium in the percolated coffee was dialysable immediately after brewing . Samples that were stored in a new aluminium percolator and reheated to 96 degrees C contained 75% dialysable aluminium. Although the levels of aluminium in percolated coffee have been measured, the bioavailability of the aluminium ingested in this way has yet to be determined.

Safety assessment of polylactide (PLA) for use as a food-contact polymer.

This report constitutes a safety assessment of polylactide (PLA), a polymer of lactic acid intended for use in fabricating various food-contact articles. Migration studies were conducted on samples of the polymer following guidelines issued by the Food and Drug Administration. Potential migrants from PLA include lactic acid, lactide (the monomer), and lactoyllactic acid (the linear dimer of lactic acid). The studies were designed to model reasonable 'worst' case extraction situations when the polymer is used (a) in houseware articles for short and intermediate time periods at various temperatures and (b) in food-packaging materials. The limited migration observed during the trials represents no significant risk since migrating species are expected to convert to lactic acid, a safe food substance. It is concluded that PLA is safe and 'Generally Recognized As Safe' for its intended uses as a polymer for fabricating articles that will hold and/or package food.

Flame burns involving kerosene pressure stoves in India.

The author has analysed 339 patients with extensive burns admitted to a teaching hospital and found them to be most common in poor socioeconomic groups with low incomes, poor housing and illiteracy. Thermal injuries afflicted 89 per cent of the patients and were generally accidental and occurred in homes with floor-level cooking: chemical and electrical burns (the remaining 11 per cent) were uncommon. Kerosene pressure stove accidents were a common cause of thermal burns and occurred in 65 per cent of the patients. These were reported in both sexes but were 3.5 times more common in females. Mishandling of kerosene pressure stoves was the commonest cause and occurred in 65.7 per cent of the patients and the next most common cause was wearing loose garments. Kerosene pressure stove accidents occurred commonly in the age group 16-35 years and were rare in other age groups. These burns were relatively more extensive, deep and carried a high mortality.
