1/15. Central palatal burns associated with the eating of microwaved pizzas.

    burns of the oral mucosa can be caused by heat, cold, radiation, electricity and mechanical or chemical stimuli. acids, alkalis and salts can cause considerable damage to the oral mucosa, membranes and lips. Most damage is found in the oropharynx, besides the pharynx and tonsils, the alveolar mucosa of the tongue and the masticatory mucosa of the palate or gingiva show localized or diffused damage. The clinical appearance depends on the severity of the tissue damage and the destructive properties and mode of application of the causative agent. We present an illustrative case of central palatal burn associated with the eating of microwaved pizzas and discuss similar mechanisms of injury.

2/15. Microwave oven injuries in patients with complex partial seizures.

    Microwave ovens are often recommended as a safe cooking alternative for persons with epilepsy. We report four patients who suffered serious burns to their hands while handling microwave-heated liquids during a complex partial seizure (CPS). Injuries were due to the contact of the skin with a very hot container. The fact that all patients held on to the hot containers despite being burned and that they did not remember experiencing any pain at the time of the accident indicates that neither high temperatures nor pain will prevent patients who are having a CPS from suffering this type of injury. Unfortunately, there is no foolproof way to prevent the individual from opening the oven and removing its contents during a CPS. The only solution for this problem is "prevention"-individuals with poorly controlled CPS should be cautioned about these risks. The use of microwave settings that permit the heating but not boiling of liquids and the use of gloves while heating food and liquids to scalding temperatures may minimize the risk of this type of injury.

3/15. Laryngeal burns secondary to the ingestion of microwave-heated food.

    Thermal injuries to the upper airway are a well-recognized complication of the inhalation of steam and hot gases, but have only rarely been reported to occur in relation to the ingestion of heated foodstuffs. We report the case of an acute laryngeal burn caused by the ingestion of a microwave-heated food product, a previously undescribed complication of ingesting microwave-processed foods.

4/15. Acute microwave injury to the hand.

    An acute microwave oven burn injury to the hand resulting in second- and third-degree burns to the left long finger is presented. Excision and coverage using a cross-finger flap resulted in full return of function. Because of the difficulty in evaluating the extent of tissue necrosis, we recommend hospitalization for most microwave injuries where obvious soft tissue damage has been sustained.

5/15. Airway burns in an infant following aspiration of microwave-heated tea.

    airway obstruction developed in an infant who sustained thermal burns to the oropharynx and trachea after he aspirated microwave-heated tea. Bronchoscopic examination revealed upper and lower airway hyperemia, edema and blister formation. physicians should be aware of this potential hazard of microwave-heated fluid. Early assessment and stabilization of the airway is important following scald injuries to the face and oropharynx.

6/15. Microwave oven burns to children: an unusual manifestation of child abuse.

    Two children sustained full-thickness burns as a result of being placed in microwave ovens. Well demarcated burns occurred on the skin surfaces closest to the microwave-emitting devices. morbidity was limited to complications of direct thermal effects. One of the children sustained a distinctive pattern of relative sparing of tissue layers without electrical burn features, such as nuclear streaming and charring, at the entrance site. In both instances eventual identification of this unusual etiology was initiated by child abuse concerns.

7/15. Can microwave/radiofrequency radiation (RFR) burns be distinguished from conventional burns?

    The literature was reviewed that addressed the differences between microwave/radiofrequency radiation (RFR) and conventional burns. It was concluded that RFR may involve deeper tissue without immediate observable skin injury or pain. Since RFR is not uniformly absorbed in tissue, "hot spots" of focal necrosis may occur such as at tissue interfaces and in tissue with poor blood supply. A followup physical examination is advisable because there may be a latent period before burns are observed.

8/15. risk factors for microwave scald injuries in infants.

    An infant sustained second- and third-degree scald burns of the oropharynx from drinking formula heated in a microwave oven. The circumstances leading to the scald injuries were recreated. Factors contributing to the injury included the volume of formula, the initial temperature of the formula, and the temperature gradient between the liquid core and the bottle surface after microwave heating. These studies indicate that infant formula should be warmed only with extreme care in microwave ovens and should be tested for suitability of temperature prior to feeding.

9/15. High-frequency electromagnetic radiation injury to the upper extremity: local and systemic effects.

    Industrial use of radiofrequency and microwave energy sources (nonionizing, high-frequency electromagnetic radiation) is a growing and widespread phenomenon, with projected risks of exposure to more than 20 million workers in the united states. A description of the nature of this form of electromagnetic energy is given, with emphasis on the variability of energy absorption by humans. The current state of biological research is reviewed, and a summary of the known effects of radiofrequency and microwave radiation exposure on animals and humans provided. These known effects appear to be principally thermal, similar to conventional electrical burn injuries, but with some unique systemic expression. Derangements of cardiovascular, gastrointestinal, endocrine, hematological, ophthalmological, and behavioral functions are well described in animal experimentation. Two patients are presented--one a young woman exposed to a high-density radiofrequency field in an industrial setting, leading to necrosis of the entire hand and wrist as well as to a constellation of systemic effects, and one an older woman exposed to excessive microwave radiation from a malfunctioning microwave oven, leading to chronic hand pain and paresthesias resembling median nerve entrapment at the carpus. The prevalence of potential exposure in certain industries is noted and recommendations for follow-up care of workers exposed to this form of trauma are delineated.

10/15. Hazards of microwave cooking: direct thermal damage to the pharynx and larynx.

    A case of a direct burn to the pharynx and larynx is described. This occurred after a patient swallowed a microwaved treacle tart. The potential danger of excessive heating of food in microwave ovens is discussed.
