HSP70 is a kind of stress protein that takes care of protein through its life, and it has attracted attention as a factor to promote health. This protein is known for its induction route through hyperthermia stimulation. We compared differences between the effects of carbonic warm water bathing and tap warm water bathing, and the report obtained interesting results. The subjects are six healthy adults (average age: 23.8±5.5 years, each three from males and females), applied full immersion bathing at 41°C for 10min in both ca. 1, 000ppm of high concentration CO2 warm water and tap warm water, and compared HSP70 before the bathing and one day after the bathing. During the observation of 24h, external thermal stimulation such as warm bathing was banned. 3 persons took warm bathing in CO2 water first and the other 3 persons took tap water first. There was 10 days interval between the bathing in both types of bathing.
The results showed that an increase in precordial temperature measured with a deep-body thermometer was 1.0°C in tap warm water bathing and 2.3°C in CO2 warm water bathing. The change in HSP70 was 3.31→4.35 (AU/mg protein: p=0.08) in tap warm water bathing and 3.42→5.04 (p<0.05) in CO2 warm water bathing. Although a slight increase was recognized in tap warm water bathing, a significant increase in HSP70 was recognized in CO2 warm water bathing.

Ginseng powder was dissolved in the warm water to develop bath salt that contained Ginseng powder (250mg: 1% Ginseng powder, 500mg: 2% Ginseng powder) and it made comparative study of the effects with the tap warm water for seven healthy adults (male 3, female 4, 20.7±0.8 years old). The Ginseng powder of 250mg and 500mg was made so that the bath salt of 25g may become 1% and 2%. The whole body immersion of 15 minutes was done to all subjects under the condition that 1% or 2% cannot be distinguished without tap water bathing.
As a result, the warm water with Ginseng powder increased in the changes of the deep thermometer in front of chest between immersion and after bathing, compared with the tap warm water. But there were not significant change of the surface skin temperature on the arm and the tissue blood flow on thigh skin.
Therefore, the warm water with Ginseng powder was suspected that the thermo effects and the retaining warmth were good compared with the tap warm water.
It seemed that it was possible to use it safely as bath salt for it did not change of the blood pressure, the heart rate, and abnormality of the skin without the case to whom the skin had temporarily flushed, was not additionally recognized.

Purpose:
Toxins produced by Clostridioides difficile infection (CDI) can cause enteritis and diarrhea. Although the number of pediatric CDI cases is increasing, the clinical management of pediatric CDI, including patient characteristics and prognosis, remains unclear. This study aimed to elucidate the background and clinical course of patients with CDI and evaluate the reliability of diagnostic tests in a tertiary pediatric hospital in Japan.
Methods:
We retrospectively analyzed the clinical data of children diagnosed with CDI between 2011 and 2021 at the Saitama Children’s Medical Center in Saitama, Japan.
Results:
During the study period, 1,252 C. difficile antigen/toxin tests were performed, and 37 patients were diagnosed with CDI. The main underlying diseases among the patients were hematological and malignant disorders and gastrointestinal diseases, including inflammatory bowel disease (IBD) (59.4%). Two patients (5.4%) had an unremarkable medical history. Among the 37 patients, 27 (73.0%) were immunocompromised, 25 (67.6%) had a history of antibiotic use within the past two months, and 6 (16.2%) were negative on the initial test but were positive on the second test. Finally, 28 patients (75.7%) required primary antibiotic therapy only, and two patients with IBD required additional antibiotic therapy as secondary treatment.
Conclusion
The number of pediatric patients with CDI is increasing. Both a comprehensive interview, including underlying diseases and history of antibiotic use, and an understanding of the features of clinical examinations should be emphasized to appropriately diagnose and treat CDI.

OBJECTIVE: This study aimed to evaluate the efficacy of magnetic resonance (MR) imaging in differentiating between cutaneous basal cell carcinoma (cBCC) and cutaneous squamous cell carcinoma (cSCC) in the head and neck region.MATERIALS AND METHODS: Among patients with cutaneous head and neck cancers, 14 with primary cBCCs and 15 with primary cSCCs with a histologic tumor height of ≥ 4 mm underwent MR examinations; the findings were then examined for correlations.RESULTS: cBCCs (71%) occurred more frequently on the nose than cSCCs (13%) (p < 0.01). The maximum diameter (23.5 ± 7.2 mm vs. 12.7 ± 4.5 mm; p < 0.01) and diameter-to-height ratio (2.8 ± 0.9 vs. 1.7 ± 0.4; p < 0.01) were significantly greater in cSCCs than in cBCCs. Superficial ulcer formation (67% vs. 21%; p < 0.05), protrusion into the subcutaneous tissue (60% vs. 21%; p < 0.05), ill-demarcated deep tumor margins (60% vs. 7%; p < 0.01), and peritumoral fat stranding (93% vs. 7%; p < 0.01) were more frequently observed in cSCCs than in cBCCs. Intratumoral T2-hyperintense foci (57% vs. 13%; p < 0.05) were more frequently observed in cBCCs than in cSCCs.CONCLUSION: cBCCs predominantly occurred on the nose with intratumoral T2-hyperintense foci, whereas cSCCs predominantly exhibited a flattened configuration, superficial ulcer formation, protrusion into the subcutaneous tissue, ill-demarcated deep tumor margin, and peritumoral fat stranding.

Hot sprigs elements and balneological effects of Tokyo 23 wards, which is not recognized as hot spring region were considered. The density of the hot spring’s source in this region is high compared to other parts of the country. Moreover, a useful element and temperature for the balneological treatment was confirmed by the hot springs with deep digging in a lot of places. The hot springs in Tokyo can be classified into the NaCl strong salt hot springs, NaHCO3, and the sodium metasilicates. The strong Na-Cl (salt) springs are recognized in hot springs found by deep digging, and exists everywhere in Tokyo. The hot springs of the NaHCO3 are localized in Ohta ward by moderate depth digging. The hot springs including with the rich sodium metasilicates in Ohta ward by shallow digging. If the hot springs in Tokyo are to be used the balneologically, the following effects are expected. Thermal and warm keeping effects can be expected from the strong Na-Cl (salt) springs. Cleanness and smoothing effects of the skin can be expected of NaHCO3. Hyperkeratosis of the skin can be expected from rich sodium metasilicates.
