So far a few case reports about laptops causing burns have been published. Now for the first time, we report on a case, in which notebook-induced thermal injuries placed in a patient's lap resulted in severe second- and third-degree burns. As a consequence, a partial amputation of the left foot had to be performed. Furthermore, we measured maximum temperatures of 12 popular laptops, which were running full load for 3 h. For this experiment air circulation underneath the device was blocked in order to simulate surrounding conditions, which were present when the patient got injured. Although this setting may be the reason for most of all notebook burns, this kind of test has not been part of any scientific publication until now. Patients with lower extremity sensation, altered consciousness or decreased peripheral sensitivity have a higher risk for thermal injuries.

    ABSTRACT: Laptop burn is a real condition and medical reports indicate that using a laptop across the legs can indeed cause it. in very rare cases, the condition can cause damage leading to skin cancer. A 24-year-old man presented with an asymptomatic reddish brown pigmentation on the thighs. After an extensive work-up, burning caused by use of a laptop was observed. Burning was induced in 3 days by using laptop for 4 h daily. Laptop should be used in properly ventilated and air-conditioned rooms. The most effective way of preventing erythema is to use the laptop on the table or desk.

    ABSTRACT: Purpose: This article investigates the safety of radiofrequency induced local thermal hotspots within a 1.5T body coil by assessing the transient local peak temperatures as a function of exposure level and local thermoregulation in four anatomical human models in different Z-positions. Methods: To quantize the effective thermal stress of the tissues, the thermal dose model cumulative equivalent minutes at 43°C was employed, allowing the prediction of thermal tissue damage risk and the identification of potentially hazardous MR scan-scenarios. The numerical results were validated by B1 (+) - and skin temperature measurements. Results: At continuous 4 W/kg whole-body exposure, peak tissue temperatures of up to 42.8°C were computed for the thermoregulated model (60°C in nonregulated case). When applying cumulative equivalent minutes at 43°C damage thresholds of 15 min (muscle, skin, fat, and bone) and 2 min (other), possible tissue damage cannot be excluded after 25 min for the thermoregulated model (4 min in nonregulated). Conclusion: The results are found to be consistent with the history of safe use in MR scanning, but not with current safety guidelines. For future safety concepts, we suggest to use thermal dose models instead of temperatures or SAR. Special safety concerns for patients with impaired thermoregulation (e.g., the elderly, diabetics) should be addressed.

    ABSTRACT: We report a case of a 29-year-old man with a background history of incomplete quadriplegia, who sustained a second degree thermal burn of the lower limb from prolonged proximity to the extractor fan of his laptop. We have also reviewed all other reported cases of thermal burns associated with laptop use. This literature review highlights the variability in the extent of injury and the subsequent management of laptop induced burns.
