BACKGROUND: Dry sauna has been very popular as an alternative therapy for promoting health among people who want to improve their health condition without relying on pharmaceuticals. The aim of this study was to investigate whether dry sauna therapy improved quality of life and reduced pain in participants with low back pain.METHODS: Study participants comprised a total of 37 consecutive patients who were over 20 years of age with low back pain. Dry sauna therapy was performed twice per day for 5 consecutive days over the course of 1 week, thus comprising a total of 10 sessions each of 15 min of exposure to a 90℃ dry sauna.RESULTS: The verbal numerical rating scale (VNRS) and Oswestry disability index (ODI) scores were significantly reduced after dry sauna therapy (P < 0.001 for both). VNRS pain scores had a median (range) of 5 (2–8) before dry sauna therapy and 3 (0–8) after dry sauna therapy. ODI scores had a median (range) of 12 (2–24) before dry sauna therapy and 8 (1–17) after dry sauna therapy. The proportion of participants who reported successful treatment (excellent + good) was 70%. No adverse effects were observed related to dry sauna therapy.CONCLUSIONS: Our results suggest that dry sauna therapy may be useful to improve quality of life and reduce pain in patients with low back pain. Therefore, pain physicians can recommend dry sauna therapy as an alternative and complimentary therapy for patients with low back pain.

OBJECTIVES: This study aimed at identifying the current nutrition knowledge, body-related perspectives, and weight control behaviors of Korean-Chinese college students. METHODS: We conducted a pilot study by employing a healthy weight education program targeting Korean-Chinese nursing school students at the Yanbian University of Science and Technology in Yanbian, China. RESULTS: This pilot study included 40 participants (38 women and 2 men; mean age, 20.5 years). The current weight status of the participants was as follows: 7.9% underweight, 78.9% normal weight, 7.9% overweight, and 5.3% obese. However, nearly two-thirds of the participants were dissatisfied with their current body size (43.6% a little dissatisfied; 20.5% very dissatisfied). Fifty percent of the participants perceived their current body size as being either slightly fat (35.0%) or very fat (15.0%). The following unhealthy weight control methods were commonly used among the 24 participants who practiced weight control: (1) laxatives or diuretics (91.7%), (2) saunas or spas (87.5%), and (3) a one-food diet (79.2%). In addition, the nutrition knowledge of the participants increased by 24 points from 117 points (pretest) to 141 points (posttest) through the healthy weight education program. CONCLUSION: The findings of this study indicate an urgent need to educate Korean-Chinese college students on healthy weight control methods and body-related perspectives.

Posterior reversible encephalopathy syndrome (PRES) is a rare disorder that is associated with hypertensive crises. In this article, we present a 59-year-old male patient with posterior reversible encephalopathy syndrome (PRES) caused by an acute hypertensive crisis after entering a steam bath in alcohol intoxicated status. In our case, oxidative stress resulting from alcohol metabolism may have lead to blood brain barrier (BBB) breakdown, serving as an aggravating factor in PRES. Thus we must always consider the possibility of PRES when treating chronic alcoholic patients with abnormal neurologic symptoms.

Fentanyl, a synthetic, highly selective opioid micro-receptor agonist, is 50 to 100 times more potent than morphine. The low molecular weight, high potency, great transdermal permeation rate and lipid solubility of fentanyl make it very suitable for transdermal administration. Durogesic is a novel matrix transdermal system providing continuous systemic delivery of fentanyl. In recently, there are many reports that misused or overused fentanyl transdermal patches result in severe intoxication of fentanyl. We present a case of fentanyl toxicity with misused durogesic transdermal patch and discuss the safe and appropriate application of the patches. In conclusion, fentanyl patches should be used in opioid tolerant patients and prescribed at the lowest possible dose and titrated upward as needed. All patients and their caregivers should be educated safe application of fentanyl patches and advised to avoid exposing the patches application site to direct external heat sources, such as heating pads, or electric blankets, heat lamps, sauna, hot tubs, and others. In addition, concomittant medications that affect fentanyl's metabolism should be avoided.

This study was performed to analyze 6 day-term variations in bacterial communities contaminating the floor of two dry saunas that were operated at 64degrees C (low temp) and 76degrees C (high temp). Bacteria were sampled daily from the saunas for 6 days from Monday to Saturday. Genomic DNA was isolated directly from bacteria-collected cotton swabs. The diversity of the bacterial communities collected from the saunas was analyzed using thermal gradient gel electrophoresis (TGGE). The total numbers of DNA bands separated by TGGE for bacteria collected from the low temp and high temp sauna were 20 and 18, respectively, during the 6 days. Seven of 20 bacteria in the low temp sauna and eight of 18 bacteria in the high temp sauna were detected more than three times over the 6 experimental days. Twelve of the 26 bacterial genera contaminating the saunas were cross detected. Bacteria belonging to the genera Moraxella and Acinetobacter were selectively detected in the low temp sauna, whereas those belonging to Aquaspirillum, Chromobacterium, Aquabacterium, Gulbenkiania, Pelomonas, and Aquitalea were selectively detected in the high temp sauna. Three species of bacteria contaminating both the low and high temp saunas were thermophile or thermoduric. The results indicate that the sauna-contaminating bacteria may have been transferred from outside the saunas by user traffic but did not inhabit the saunas.

The purpose of this study was to examine profile of bacteria contaminated in a dry sauna. Bacteria sampled from the floor of the dry sauna (75~80degrees C) were separated and identified by using a thermal gradient gel electrophoresis (TGGE) technique, and were cultivated using a defined medium at 50degrees C. Bacteria grown in the defined medium were identified based on 16S-rDNA sequence homology. The band number of DNA separated by TGGE was 15, indicating the species diversity of bacteria contaminating the dry sauna. Seven species of bacteria were successfully cultured on agar plate medium at 50degrees C, which represented a combination of thermophilic and thermoduric bacteria contaminating the dry sauna. The highest limit temperature for growth of the bacterial isolates was generally 50degrees C when cultivated in a defined medium, but was raised to 60degrees C when cultivated in a complex medium. Consequently, the bacteria grown at 50~60degrees C are thermoduric or thermophilic, but others may not be.

BACKGROUND: Waon therapy has beneficial effects on chronic heart failure (CHF), peripheral arterial disease, and other various diseases. This was to assess the safety and effect of Waon therapy by echocardiography for the first time in Korea. METHODS: Ten patients with CHF were enrolled. The patients with a light gown were placed in a sitting-position in an evenly maintained 60degrees C dry sauna system for 15 minutes, and then after leaving the sauna, they underwent bed rest with a blanket to keep them warm for an additional 30 minutes. Waon therapy was performed once a day, 5 days a week. RESULTS: Four of the 5 patients who had been treated for more than 2 weeks as protocol noted improvement of heart failure (HF) symptoms and decrease in left ventricular (LV) volume. There were trends in improvement of LV ejection fraction and parameters of diastolic function after the therapy although statistical significance was lack. No one complained of worsening of HF symptoms. In each session, body weight (61.8+/-10.2 kg vs. 61.6+/-10.3 kg, p=0.008) and blood pressure (systolic, 119+/-28 vs. 111+/-27 mmHg, p=0.005; diastolic, 69+/-12 mmHg vs. 63+/-10 mmHg, p=0.005) were significantly decreased, oral temperature (35.9+/-0.4degrees C vs. 37.0+/-0.9degrees C, p=0.017) was increased by 1.0degrees C at the end of sauna bathing, but the heart rate (71+/-10/min vs. 72+/-8/min, p=0.8) was not changed. CONCLUSION: We have experienced Waon therapy which was safe and well tolerated and some beneficial effects for patients with CHF. Large scale randomized study is needed to apply Waon therapy as a promising therapy in Korean HF patients.

PURPOSE: Burn injuries still produce a significant morbidity and mortality. The collection and analysis of burn epidemiology data would provide insights into new prevention management strategies in terms of nationwide profile. We reviewed and compared the data from other countries. METHODS: This study was carried out to analyze the epidemiology, current etiological factors (circumstances), treatment methods and mortality of 4,321 acute burn patients, excluding electrical burn, who were admitted to Hanil Hospital Burn Center during 12 years (1996~2007). RESULTS: 1) The male to female ratio was 1.3:1. The mean age of admission was 30.0 years. The children below 18 years made up 38.9%, and adult over 60 years 10.2%. 2) The scald was the most common cause making up 53.8% followed by flame (30.8%), contact (9.3%), steam (3.6%) and chemical (2.1%) burn. The mean extent was 9.8%, 19.1%, 3.8%, 7.2%, 8.7% respectively. 3) The etiologies of scald burn were boiled water (32.9%), hot food soup (28.1%), boiling water (13.8%), instant food (10.3%) at home (87.4%). The 13.7% of victims underwent surgery of STSG (12.9%), FTSG (0.6%), local flap (1.2%) and advanced flap (0.1%). 4) The majority of flame burn occurred at home (43.7%) and work place factory (23.5%). Leading causes were inflammables (29.3%), fire (14.0%), explosion of butane can (12.8%), gas range (10.1%) and LPG (8.7%). The 31.4% of victims underwent STSG (26.2%), FTSG (0.8%), local flap (0.2%) and major amputation (0.1%). 5) The major victims (50.6%) of steam were children below 2years by exposing to steam of rice cooker (70.0%) at home. The 28.9% of victims underwent STSG (14.7%), FTSG (16.0%) and local flap (5.1%). 6) The contact burns occurred at various places (home; 56.5%, work place; 16.9%, vehicles; 9.0%, sauna; 4.5%) by various causes (Ondol; 11.9%, hot pack; 11.2%, oriental herb medicine; 6.7%). The 45.8% of victims underwent STSG (36.3%), FTSG (6.7%), local flap (5.2%), advanced flap (2.0%) and minor amputation (1.2%). 7) The chemical burn occurred at various place (home; 39.3%, work place; 49.4%) by acids (43.8%), alkalies (11.2%), vinegar (15.7%) and herb moxa (16.9%). The 28.1% of victims underwent STSG (22.5%), FTSG (9.0%), local flap (7.9%) and minor amputation (6.7%). 8) Children<18 years old were burnt mainly by scald (79.0%) while for adults below 50 years old was flame, over 50 years was scald. Children below 2 years old had higher frequency of steam (9.2%) and contact (7.9%) burn. The contact burn had relatively higher frequency among 7th (17.6%) and over 8th (20.4%), while chemical among 6th (3.9%) decade. 9) Inhalation injury was accompanied in 13.8% of flame burn (4.3% of total). The inhalation injury only was 4.9% of flame (1.5% of total). 10) The overall mortality rate was 1.8%. The mean age of death was 47.3 years old and burn extent was 74.5%TBSA. There was a strong correlation between flame burn (96.2% of total death), TBSA (50~60%; 9.3% vs 70~80%; 65.2%, 80~90%; 71.4%, over 90%; 87.9%) and mortality. The prognosis was poor for those over 70 year old (7.7% vs 30~50 yo; 2.8%, 7 th decade; 3.7%), flame burn (5.6% vs scald; 0.04%) and combined inhalation injury (22.3%). The patients died at mean 17.3 PBD by ARDS (51.3%), sepsis (44.9%), burn shock (20.5%) and ARF (5.1%) 11) The severity and sequelae of scald by prepackaged instant food, steams of rice cooker, flame by used butane can, contact by Ondol, sauna and chemical by vinegar should be added to preventive programs. CONCLUSION: Further study for implications of changes in management protocols and policies on treatment outcomes would improve the provision of appropriate care for the patients.

Rhabdomyolysis is a syndrome involving the breakdown of skeletal muscle, and this causes myoglobin and other intracellular proteins and electrolytes to leak into the circulatory system. We report here on a case of rhabdomyolysis associated with statin, exercise and sauna exposure. A 63-year-old woman presented to our hospital, and she had been taking simvastatin for over 6 years due to dyslipidemia. She complained of developing myalgia and weakness of the lower extremities over the previous 5 days. She had used a sauna more than 4 hours daily for 20 years, and she had started unaccustomed exercise in the sauna 1 week prior to admission. Her serum creatine kinase concentration was 45,990 IU/L. Conservative treatment was started with the discontinuation of her statin medication, exercise and use of the sauna. Her symptoms and serum creatine kinase level decreased 1 week after admission and she was discharged with minimal residual muscle weakness.

OBJECTIVETo investigate effects of cigarette, alcohol consumption and sauna on sperm morphology.

METHODS602 cases of male infertility were selected from our case database, who were divided into three subgroups: smoking (243) , drinking(224), sauna(135) and those without any of the above habits were taken as the corresponding controls. The sperm morphology were analyzed by automated sperm morphology analyzer(ASMA). A questionnaire was voluntarily filled out by patients in order to investigate cigarette, alcohol consumption and sauna frequency.

RESULTSThe normal morphologic sperm rates in cigarette, alcohol consumption and sauna groups were lower than those in the corresponding control groups, respectively(P <0.05, P <0.001). Percentages of irregularity head sperm were higher than those in normal controls, respectively(P <0.05).

CONCLUSIONCigarette, alcohol consumption and sauna could affect sperm morphology, especially caused increasing of irregularity head sperm.
