We investigated the effects of artificial mineral bathing in water containing sodium sulfate and sodium bicarbonate on venous blood gas, blood pressure, heart rate, and deep body temperature in 10 patients with hypertension or history of hypertension. After a 10-minute bathing at 40°C, the parameters described above were carefully checked. The pH and PO2 levels in venous blood increased and the PCO2 level decreased after the artificial mineral bathing in comparison with plain water bathing. However, these changes were not statistically significant. The systolic blood pressure tended to decrease up to 10 hours after the artificial mineral bathing. The heart rate markedly reduced after the artificial mineral bathing and remained at a low level for 10 hours. The deep body temperature began to decrease 40 minutes after the artificial mineral bathing. However, it increased over the base-line level 6 hours later. From the above result, it is considered that artificial mineral bathing is useful for patients with hypertension.

It has been made known that there isn't any significant regional difference in the frequencies of cases of viral hepatitis C by subtypes in our country. In the present study we investigated the subtypes in hepatitis C virus carring patients without blood transfusion history in the southern region of Ibaraki Prefecture to clarify the occurrence ratio of each subtype of the virus. The results of interferon therapy were also examined in those patients with chronic hepatitis C. The frequencies of subtypes 2, 3 and 4 were found to be 71%, 16% and 10%, respectively. Although these ratios were the same as the national average, a significantly high frequency (P>0.01) of subtype 3 was observed in the patients from Tsuchiura in the region, suggesting that there may have existed some particular source of infection other than blood transfusion. The effectiveness of interferon therapy was significantly higher (P>0.01) in the patients with subtype 3 (75%) than in those patients with subtypes 2 and 4 (23% and 43%, raspectively), suggesting that interferon is a remedy specific to subtype 3.

BACKGROUND: We investigated whether the calcar femorale, a cortical septum in the region of the lesser trochanter of the femur, correlates with results of femoral stem implantation in patients with osteoarthritis of the hip secondary to developmental dysplasia using computed tomography. METHODS: This retrospective study included 277 hips (41 males and 236 females; age, 37 to 92 years) of patients who had presented to Okayama Medical Center with hip pain. Of these, a total of 219 hips (31 males and 188 females) had previously undergone total hip arthroplasty. According to the Crowe classification, 147 hips were classified as Crowe grade I, 72 hips as Crowe grade II–IV, and 58 hips as normal. RESULTS: The calcar femorale was identified in 267 hips (96.4%). The calcar femorale was significantly shorter and more anteverted in Crowe grade II–IV hips than in Crowe grade I or normal hips. Significant differences in the shape of the calcar femorale were found according to the severity of hip deformity. Three stem designs were analyzed: single-wedge (59 hips), double-wedge metaphyseal filling (147 hips), and modular (13 hips). Single-wedge stems were inserted more parallel to the calcar femorale rather than femoral neck anteversion, while other types of stems scraped the calcar femorale. CONCLUSIONS: The angle of the calcar femorale differs according to the severity of hip deformity, and the calcar femorale might thus serve as a more useful reference for stem insertion than femoral neck anteversion in total hip arthroplasty using a single-wedge stem.

Chronic kidney disease (CKD) has recently been reported to be an independent risk factor for stroke. However, a detailed analysis was yet to be conducted according to stroke subtype. We attempted to determine the risk factors for stroke using data from the “specific health checkup” for metabolic syndrome conducted by the 9 hospitals affiliated with the Akita Prefectural Federation of Agricultural Cooperatives, and evaluate and determine the risk factors for stroke. There were 401 patients who had undergone metabolic syndrome checkups from 2007 and 2010 and suffered from stroke afterwards within 3 years after the screening. The controls were all 69,407 subjects who were screened during the same period. The predictors examined were sex, age, blood pressure, BMI, cholesterol values (HDL・LDL), history of diabetes mellitus, presence of atrial fibrillation, CKD, and drinking and smoking habits. Analysis was conducted using logistic regression. The risk factors for stroke as a whole were male sex, age, blood pressure, diabetes, atrial fibrillation, CKD, and smoking history. For cerebral infarction, the risk factors were male sex, age, blood pressure, diabetes, atrial fibrillation, CKD, and smoking habit. The risk factors for cerebral hemorrhage were age, blood pressure, and CKD. For subarachnoid hemorrhage, the risk factors were female sex, age, blood pressure, low HDLemia, and CKD. In conclusion, CKD is an independent risk factor for the 3 subtypes of stroke, and in particular plays an important role as a higher risk factor for cerebral hemorrhage. Smoking cessation and controls of blood pressure, diabetes and atrial fibrillation are the important measures for stroke prevention. In addition, the further intervention should also be targeted to those with the result of CKD revealed by specific health checkups.
