“…During the night there was a sizable increase in peripheral temperature, with a decrease in gradient and a loss of complexity in the temperature profile, most significantly in the peripheral temperature. A detailed clinical evaluation can be found in [27]. …”

We describe a device for dual channel body temperature monitoring. The device can operate as a real time monitor or as a data logger, and has Bluetooth capabilities to enable for wireless data download to the computer used for data analysis. The proposed device is capable of sampling temperature at a rate of 1 sample per minute with a resolution of 0.01 °C . The internal memory allows for stand-alone data logging of up to 10 days. The device has a battery life of 50 hours in continuous real-time mode. In addition to describing the proposed device in detail, we report the results of a statistical analysis conducted to assess its accuracy and reproducibility.

“…For example, this parameter has been successfully applied in recent works to investigate the influence of levodopa therapy on individuals with Parkinson's disease (29) and to develop new diagnostic and prognostic tools in patient management (55). Other important clinical studies have been recently conducted to investigate voice disorders.…”

Airflow pattern complexity and airway obstruction in asthma

The scientific and clinical value of a measure of complexity is potentially enormous because complexity appears to be lost in the presence of illness. The authors examined the effect of elevated airway obstruction on the complexity of the airflow (Q) pattern of asthmatic patients analyzing the airflow approximate entropy (ApEnQ). This study involved 11 healthy controls, 11 asthmatics with normal spirometric exams, and 40 asthmatics with mild (14), moderate (14), and severe (12) airway obstructions. A significant (P < 0.02) reduction in the ApEnQ was observed in the asthmatic patients. This reduction was significantly correlated with spirometric indexes of airway obstruction [FEV(1) (%): R = 0.31, P = 0.013] and the total respiratory impedance (R = -0.39; P < 0.002). These results are in close agreement with pathophysiological fundamentals and suggest that the airflow pattern becomes less complex in asthmatic patients, which may reduce the adaptability of the respiratory system to perform the exercise that is associated with daily life activities. This analysis was able to identify respiratory changes in patients with mild obstruction with an adequate accuracy (83%). Higher accuracies were obtained in patients with moderate and severe obstructions. The analysis of airflow pattern complexity by the ApEnQ was able to provide new information concerning the changes associated with asthma. In addition, this analysis was also able to contribute to the detection of the adverse effects of asthma. Because these measurements are easy to perform, such a technique may represent an alternative and/or a complement to other conventional exams to help the clinical evaluations of asthmatic patients.

Neurogenic fever in a patient with a chordoid glioma

Chordoid gliomas are rare tumours. Despite being considered low-grade neoplasms, recent reviews have reported generally poor prognosis due to complications involving severe hypothalamic symptoms. We report a patient aged 30 years with chordoid glioma. What makes this case report interesting is the presence of neurogenic fever, which was already present before the final diagnosis of the brain tumour and also several months after the surgical removal. Since the patient underwent a subtotal resection of the tumour, it remains unclear whether the fever was due to hypothalamic dysfunction or remnants of the tumour. We also performed temperature logging with a continuous-monitoring recording device.
