Hot, humid conditions in tropical regions generally rule out any risk of hypothermia due to cold exposure. In this report, we describe a case of severe hypothermia involving a core temperature of 26 degrees C in a 61-year-old man living in Gabon. Parkinson's disease and chronic alcoholism may have been predisposing factors. The patient was treated by active and passive rewarming (intestinal irrigation with warm water). Sudden circulatory collapse occurred during treatment but the final outcome was successful. This case demonstrates that hypothermia can occur in tropical areas. Emergency diagnosis may be difficult in Black Africa where adequate temperature monitoring equipment is rarely available. Standard mercury thermometers do not allow measurement of temperatures lower than 34 degrees C. African physicians should be aware of the possibility of potentially life-threatening hypothermia and be prepared to initiate proper treatment and surveillance in intensive care.

The measurement of core temperature is important for many clinical situations including heat illnesses, hypothermia, infections, sepsis, shock, hemorrhage, and exposure to chemical and biological agents. Currently, oral and rectal temperatures are clinically utilized for such measurements. However, oral measurements are not always possible and accurate whereas rectal measurements are not convenient in the field, are labor intensive, use fragile glassware containing mercury--an environmental contaminant, require sterilization and are not suited for mass casualties. A simple, non-invasive, non-breakable, inexpensive device to measure core temperature, which is not labor intensive, would have great use in the field and in hospitals, as well as provide an important advance in instrumentation for experimental physiology. The purpose of this work is to evaluate the different methods for core temperature measurement. Since the middle of the 18th century, the mercury thermometer has been almost the only instrument for measuring core temperature. Today, more sophisticated methods and instruments are gaining popularity. In addition, new promising converted techniques, which are about to enter the market and increase the available variety of instruments, might improve the situation as far as reliability and convenience of use are concerned. Despite the importance and usage of this variable, the progress in this field has been slower than would have been expected.

Climatic injuries, including hypothermia, hyperthermia and heat stroke, are common in many sports activities. Body core temperature (T(c)) measurement for the sportsperson can influence individual performance and may help to prevent injuries. Monitoring internal body T(c) accurately requires invasive methods of measurement. The mercury thermometer, most commonly used to measure oral temperature (T(oral)), has been almost exclusively the only instrument for measuring T(c) since the 18th century. Rectal (T(re)) and oesophageal temperatures (T(oes)) have been the most preferred measurement sites employed in thermoregulatory investigations. However, these measurement sites (T(re), T(oes), T(oral)), and the methods used to measure T(c) at these sites, are not convenient. T(oral) measurements are not always possible or accurate. T(oes) is undesirable because of the difficulty of inserting the thermistor, irritation to nasal passages and general subject discomfort. T(re) is not suitable under many circumstances as it is labour intensive and has a prolonged response time. However, T(re) remains the most accurately available method for monitoring T(c) in thermal illness that occurs during sports activities. In addition, T(re) and T(oes) require wire connections between the thermistor and the monitoring device. The purpose of this paper is to review the various existing methods of T(c) measurements in order to focus on the breakthrough needed for a simple, noninvasive, universally used device for T(c) measurement which is essential for preventing climatic injuries during sports events.

Neonatal hypothermia is the fourth leading causes of neonatal death in Nepal. Thus, it is the caregivers' responsibility to identify the hypothermia by using valid and less time consuming method like hand-touch method. Therefore, we examined the diagnostic validity of hand-touch method against low-reading mercury (LRM) thermometer for detecting neonatal hypothermia. We assessed neonate's temperature first by hand-touch method, then by LRM thermometer and tympanic thermometer among 100 full-term neonates, delivered within 24 h in Maternity Ward of Tribhuvan University Teaching Hospital, Nepal. We used World Health Organization (1997) criteria for classification of neonatal hypothermia. The sensitivity and specificity of the hand-touch method for detection of neonatal hypothermia were 95.6% and 70.1% against LRM thermometer and 76.6% and 83% against the tympanic thermometer, respectively. Touching method is practical and therefore has a good diagnostic validity; it can be introduced in essential newborn care package after giving adequate training to caregivers.

We report a case of 27-year-old male with lung contusions related acute respiratory distress syndrome (ARDS) managed by ARDSNet guidelines and additional hypothermia. On 4(th) day, post trauma partial pressure of oxygen dropped to 38 mm of mercury (Hg), not improving even on high positive end-expiratory pressure of 18 cm water (H2O), inverse ratio ventilation and fraction of inspired oxygen of 1. Extracorporeal membrane oxygenation was ruled out due to the risk of hemorrhage from trauma sites. Thereafter, hypothermia along with muscle paralysis was considered to reduce total body oxygen consumption. Patient's condition improved under hypothermia, and he was extubated and taken up for fracture fixation surgeries and discharged later in stable condition.
