BACKGROUND: The precise measurement of body temperature during anesthesia is important to prevent hypothermia.The aim of this study was to compare the urinary bladder temperature to the esophageal, nasopharyngeal, rectal and skin temperatures, and to compare three heating methods during spine surgery. METHODS: Forty-two patients with ASA physical status I-II, who were scheduled to undergo spine surgery in the prone position, were included in this study.The patients were randomly divided into 4 groups:Group I was treated without any heating methods; group 2, with fluid-warmers; group 3, with forced air-warmers; and group 4, with a combination of both heating methods.After the induction of anesthesia, the esophageal, nasopharyngeal, rectal, urinary bladder and skin temperature was monitored every 15 minute for 3 hours.The urinary bladder temperature was compared to the esophageal, nasopharyngeal, rectal and skin temperatures. RESULTS: The urinary bladder temperature was found to be higher than the esophageal and the nasopharyngeal temperatures (P < 0.01).The urinary bladder temperature of group 3 was higher than that of group 1 at 180 minutes after induction of anesthesia (P < 0.05).The urinary bladder temperature of group 4 was higher than that of group 1 at 150 minutes (P < 0.05), as well as at 165 and 180 minutes (P < 0.05).The skin temperatures of groups 3 and 4 were higher than group 1 (P < 0.001). CONCLUSIONS: The urinary bladder temperature was higher than the esophageal temperature and correlated with the esophageal, nasopharyngeal and rectal temperatures.During spine surgery in the prone position, a forced air-warmer was found to be the most effective but a combination of all the methods tested was found to be even more effective.

BACKGROUND: Three isoforms of the neuronal acetylcholine receptors (AChRs) have been described in muscle epsilonAChRs, gammaAChRs and alpha7AChRs. The adult neuromuscular junctions are composed of epsilonAChRs. During immobilization, new AChRs with subunit compositions of gammaAChRs and alpha7AChRs appear in the perijunctional and extrajunctional area. This study evaluated the contribution of these isoforms to neurotransmission during immobilization, by using waglerin-1 which selectively blocks the epsilonAChRs. METHODS: Male mice (n = 20) were used and each group was divided into sham operated or immobilized. A leg was immobilized in mice for 14 days by pinning, after which nerve-evoked twitch tension was examined under anesthesia in tibialis muscle of both legs, with the contralateral leg serving as control. Neuromuscular transmission was monitored by using a peripheral nerve stimulator with the tibialis muscle and sciatic nerve. Electrical stimuli of 0.2 msec duration were applied to sciatic nerve 2 Hz for 2 sec every 30 sec. After administration of waglerin-1, the evoked twitch was recorded. The percent depression of T1 relative to baseline was transformed to probit scale to determine the effective dose of waglerin-1 for 5%, 50%, and 95% twitch depression. RESULTS: The twitch tension in the control group was higher than immobilized group, confirming the efficacy of immobilization. Waglerin-1 produced 99% twitch suppression on the control group. But on the immobilized group, waglerin-1 produced only 70% twitch suppression even at 37 pg. CONCLUSIONS: The functional role of epsilonAChRs in neurotransmission decreases during immobilization while that of gammaAChRs and alpha7AChRs increases.

OBJECTIVES: This study assessed the accuracy of the 24-hour diet recall method for estimating the energy intake of elderly men using the doubly labeled water as a reference method. METHODS: Seventeen subjects (mean age 72.5 ± 3.9 years), who maintained the same body weight during the two weeks study period, were included in this study. Three 24-hour diet recalls (two weekdays and one weekend) were obtained over a 14 day period to estimate the mean energy intake. The total energy expenditure was measured over the same 14 days using the doubly labeled water method. The total energy intake and total energy expenditure were compared by paired t-test. RESULTS: The total energy intake from the 24-hour diet recalls method was 2536.7 ± 350.6 kcal/day, and the total energy expenditure from the doubly labeled water method was 2659.8 ± 306.8 kcal/day. The total energy intake was slightly under-reported by −123.2 ± 260.8 kcal/day (−4.4%). On the other hand, no significant difference was observed between the total energy intake and total energy expenditure of the subjects (p=0.069). The percentage of accurate predictions was 64.7%. The correlation between the total energy intake and total energy expenditure was statistically significant (r=0.697, p < 0.005). CONCLUSIONS: The present study supports the use of the 24-hour diet recall method to estimate the mean energy intake in elderly men group. More studies are needed to assess the validity of 24-hour diet recall method in other population groups, including elderly women, adults and children.

Pulmonary edema is a potentially life-threatening complication of acute airway obstruction. Occasionally, patients experience sudden, unexpected and severe pulmonary edema during treatment of upper airway obstruction. Two forms of postobstructive pulmonary edema (POPE) have been identified. Type I POPE follows a sudden, severe episode of upper airway obstruction and type II POPE develops soon after the relief of chronic upper airway obstruction. The pathogenesis of POPE is multifactorial. The application of moderate continuous positive airway pressure in conjunction with the administration of diuretics usually clears pulmonary edema in these clinical settings within 24 hours. Awareness of this uncommon condition is crucial for the otolaryngologist to make an early diagnosis and initiate successful treatment. We present two cases of postobstructive pulmonary edema after treatment for upper airway obstruction.

The objective of this study was to analyze the influence of socio-demographic factors on food consumption frequencies among adolescents in Korea. Data were obtained from the Seventh Korea Youth Risk Behavior Web-based Survey (2011 KYRBS), a nationwide representative sample of 75,643 (37,873 males and 37,770 females) middle and high school students. It was carried out as a self-administered on-line survey. The frequency of eating breakfast was 4.8 times per week for middle school students and 4.6 times per week for high school students (p < 0.001). Higher levels of perceived household economic status, family affluence scale (FAS) and education attainment of mother were associated with more frequent breakfast eating. The frequencies of consumption of vegetables and milk were higher in males than in females (p < 0.001). The frequency of consumption fruits was higher in females than in males (p < 0.01). Higher levels of perceived household economic status, FAS and education attainment of mother were associated with more frequent consumption of vegetable, fruits and milk. The frequencies of consumption of soda, fast food and instant noodls were higher in males than in females (p < 0.001). The frequency of consumption of snacks was higher in females than in males. Adolescents with lower levels of FAS and education attainment of mother were at risk for skipping breakfast and consuming of soda, fast food and instant noodls more frequently. Whereas, adolescents with higher levels of FAS, education attainment of mother were more likely to be frequent consumers of vegetable, fruits and milk. These findings demonstrated that being high school students and belonging to lower level of socio-economic status (SES) were associated with undesirable food habits.

Genistein is one of isoflavones mostly derived in a leguminous plant. It is well known as one of phytoestrogens that have structures similar to the principal mammalian estrogen. It has diverse biological functions including chemopreventive properties against cancers. Anticancer efficacies of genistein have been related with the epidemiological observations indicating that the incidence of some cancers is much lower in Asia, where diets are rich in soyfoods, than Western countries. This review deals with in vivo anticancer activities of genistein identified in animal studies being divided into its effects on carcinogenesis and cancer progression. Because animal studies have advantages in designing the experiments to suit the goals, they imply diverse information on the anticancer activity of genistein. The in vivo animal studies have adopted the specific animal models according to a developmental stage of cancer to prove the anticancer efficacies of genistein against diverse types of cancer. The numerous previous studies insist that genistein effectively inhibits carcinogenesis in the DMBA-induced animal cancer models by reducing the incidence of adenocarcinoma and cancer progression in the transgenic and xenograft animal models by suppressing the tumor growth and metastatic transition. Although the protective effect of genistein against cancer has been controversial, genistein may be a candidate for chemoprevention of carcinogenesis and cancer progression and may deserve to be the central compound supporting the epidemiological evidence.

30-year-old male was admitted with general weakness and drowsy mental status. He had eaten only 3-4 spoons of brown rice and fresh vegetable without salt for 3 months to treat his tic disorder, and he had been in bed-ridden state. He has had weight loss of 14 kg in the last 3 months. We report a patient with orthorexia nervosa who developed hyponatremia, metabolic acidosis, subcutaneous emphysema, mediastinal emphysema, pneumothorax, and pancytopenia and we will review the literature. Also, we mention to prevent refeeding syndrome, and to start and maintain feeding in malnourished patients.

According to WHO global estimates from 2008, more than 1.4 billion adults were overweight and among them, over 200 million men and 300 million women were obese. Although the main treatment modalities for overweight and obese individuals remain dieting and physical exercise, the synthetic anti-obesity medications have been increasingly used due to their perceived convenience. Generally, anti-obesity medications are classified as appetite suppressants or fat absorption blockers. In the present study, we examined the adverse side-effects in respect of behavior changes of phentermine and Ephedra sinica (mahuang) that are anti-obesity drugs currently distributed to domestic consumers. Phentermine is mainly classified as an anorexing agent and mahuang a thermogenic agent. Because phentermine and mahuang are considered to display effectiveness through the regulation of nerve system, their potential influences of on behavioral changes were examined employing animal experiments. From the results of experiments testing locomotor activity through the use of treadmill, rota-rod, and open field system, phentermine and mahuang were commonly revealed to induce behavioral changes of rats by reducing a motor ability, an ability to cope with an external stimulus, and a sense of balance or by augmenting wariness or excitement. These adverse effects of phenternime and mahuang in behavioral changes need to be identified in humans and anti-obesity medications such as phentermine and mahuang should be prescribed for only obesity where it is anticipated that the benefits of the treatment outweigh their potential risks.

Purpose: This study evaluated the accuracy of the 24-hour diet recall method for estimating energy intakes in elderly women using the doubly labeled water (DLW) method. Methods: The subjects were 23 elderly women with a mean age of 70.3 ± 3.3 years and body mass index (BMI) of 23.9 ± 2.8 kg/m 2 . The total energy expenditure (TEEDLW ) was determined by using the DLW and used to validate the 24-hour diet recall method. The total energy intake (TEI) was calculated from the 24-hour diet recall method for three days. Results: TEI (1,489.6 ± 211.1 kcal/day) was significantly lower than TEEDLW (2,023.5 ± 234.9 kcal/day) and was largely under-reported by −533.9 ± 228.0 kcal/day (−25.9%). The accurate prediction rate of elderly women in this study was 8.7%. The Bland-Altman plot, which was used to evaluate the TEI and the TEEDLW , showed that the agreement between them was negatively skewed, ranging from −980.8 kcal/day to −86.9 kcal/day. Conclusion This study showed that the energy intake of elderly women was underreported.Strategies to increase the accuracy of the 24-hour diet recall methods in the elderly women should be studied through analysis of factors that affect underreporting rate. Further studies will be needed to assess the validity of the 24-hour diet recall method in other population groups.
