Juzentaihoto (TJ-48), a traditional Japanese herbal medicine, influences hemoglobin recovery during preoperative autologous blood donation and after hip surgery.

OBJECTIVE: Preoperative autologous blood donation is a widely used alternative to allogenic transfusion in hip surgery. However, it has been reported that autologous blood donation may induce preoperative anemia. Juzentaihoto (TJ-48) (Tsumura Co., Tokyo, Japan) is a Japanese herbal medicine that has been used to alleviate anemia. We investigated the effect of TJ-48 on anemia in the perioperative period. PATIENTS AND METHODS: 18 hips of 18 female patients who underwent total hip arthroplasty or rotational acetabular osteotomy (RAO) were divided into two groups. Group A consisted of 9 hips of 9 patients who were treated with TJ-48 at a dose of 7.5 g per day from 21 days before surgery to the day before surgery. Group B consisted of 9 hips of 9 patients who did not take TJ-48. Preoperative autologous blood donation was performed 21, 14 and 7 days before surgery. All patients deposited 400 ml each time for a total of 1,200 ml. Hemoglobin level was recorded on preoperative Days 21, 14 and 7 and postoperative Days 1, 4, 7 and 14. RESULTS: During the preoperative period, repeated measures ANOVA showed a significant difference between the two groups in hemoglobin level (p = 0.04). Despite the lack of TJ-48 after surgery, the rate of hemoglobin decline in Group A was less than in Group B at all examination times. No patients with TJ-48 experienced side effects, including gastrointestinal symptoms and unusual laboratory data. CONCLUSION: TJ-48 is useful for treating anemia during preoperative autologous donation.

Quantification of hardness, elasticity and viscosity of the skin of patients with systemic sclerosis using a novel sensing device (Vesmeter): a proposal for a new outcome measurement procedure.

OBJECTIVES: No objective method to measure skin involvement in SSc has been established. We developed a novel method using a computer-linked device to simultaneously quantify physical properties of the skin such as hardness, elasticity and viscosity. METHODS: Skin hardness was calculated by measuring the depth of an indenter pressed onto the skin. The Voigt model was used to calculate skin elasticity, viscosity, visco-elastic ratio and relaxation time by analysing the waveform of skin surface behaviour. The results were compared with the modified Rodnan skin score (mRSS) obtained at 17 sites on the bodies of 20 SSc patients and 20 healthy controls. A functional assessment questionnaire was administered to determine how skin hardness represents a patient's disability. We also examined intra- and inter-observer variability to determine the reliability of this method. RESULTS: The crude hardness obtained with this device correlated well with the standard hardness specified by the American Society for Testing and Materials (ASTM, r = 0.957). A close relationship between hardness and total mRSS was also observed (r = 0.832). Skin elasticity correlated positively, and relaxation time negatively with mRSS. Functional disability correlated more closely with skin hardness (r = 0.643) than with mRSS (r = 0.517). Intra- and inter-observer variabilities were 7.63 and 19.76%, respectively, which were lower than those reported for mRSS. CONCLUSIONS: Increases in hardness and elasticity as well as shortening of relaxation time constitute objective characteristics of skin involvement in SSc. The system devised by us proved to be able to assess skin abnormalities of SSc with high reliability.

Giant unruptured aneurysm of the thoracic aorta--a case report.

An asymptomatic 88-year-old woman underwent a screening medical examination. The chest x-ray film showed a large mediastinal mass with calcification. Both chest computed tomography and nuclear magnetic resonance imaging revealed an unruptured aortic aneurysm, predominantly affecting the ascending aorta and the proximal part of the aortic arch. Its maximum diameter was 10.5 cm. An ascending aortic aneurysm more than 10 cm in diameter is very rare. She died of acute pulmonary embolism unrelated to the aneurysm, and autopsy indicated that the etiology of the aneurysm was atherosclerotic degeneration. Retrospectively, the natural progression of the aneurysm was able to be followed on a series of chest x-ray films obtained over 18 years.
