Studies on the effects of heating as well as the mineral components of hot spring water have been conducted to investigate the effects of balneotherapy. However, few studies have been conducted on the effects of hydrostatic pressure and buoyancy during water immersion. Therefore, we investigated the effect of water immersion up to the neck at thermoneutral temperature on hemostatic activity.
Nine healthy men aged 22 to 34 were immersed up to the neck in the standing position in thermoneutral water (34.0±0.5°C) for two hours. The heart rate decreased immediately after starting water immersion and remained low during the immersion. Hematocrit values (Ht) of the blood samples taken from the ante-cubital vein decreased by 3.4% in average. The decrease in Ht was more prominent in the blood samples taken from the earlobe (4.0%), suggesting that hemodilution due to fluid shift was stronger in the upper part of the body. The time until euglobulin clot lysis shortened immediately after starting the immersion. Although fibrinolytic activity was enhanced, the concentration of tissue plasminogen activator (t-PA) antigen in the blood decreased gradually during the immersion and tended to return to the original level 30 minutes after immersion. A larger decrease in the concentration of plasminogen activator inhibitor-1 (PAI-1) antigen in the blood was observed immediately after starting the immersion, and it remained low for 30 minutes after immersion. An increase in fibrinolytic activity due to the decrease in PAI-1, not in t-PA, was observed during water immersion at thermoneutral temperature and the activation of fibrinolytic system without activation of the coaguration system was also observed.

Objective: The purpose of this study was to assess the treatment outcome in patients with chronic hepatitis C (CHC) using the current standard antiviral therapy when patient were treated in collaboration between hepatologists and primary care physicians (PCPs).Patients and Methods: One hundred and ten patients with CHC were treated with a combination therapy of peginterferon-alpha 2b and ribavirin. Among them, 25 patients were treated by a collaboration between hepatologists and PCPs (collaboration group), whereas 85 patients were treated with exclusively by hepatologists (noncollaboration group). The duration of the therapy was 48 weeks for 58 'difficult- to-treat' patients (genotype 1 with a high load of HCV-RNA; 1H patients) and 24 weeks for the remaining 52 patients (non-1H patients). In the collaboration group, antiviral therapy was initiated and adjusted, if needed, by hepatologists (visits every four weeks), whereas the weekly administration of peginterferon-alpha 2b was performed by PCPs. Clinical characteristics and the treatment outcome were compared between these two groups.Results: The two groups had similar baseline characteristics. By intention to treat, the two groups showed similar rates of treatment-related serious adverse effects (0% vs. 1%, respectively) and dropout rates for adverse effects (8% vs. 13%, respectively). Sustained virologic response rates were also similar between the two groups, being 42% vs. 39% in the 58 1H patients (NS) and 62% vs. 64% in the 52 non-1H patients (NS), respectively.Conclusions: Collaboration between hepatologists and PCPs may be a valid treatment alternative to treat patients with CHC using the current standard antiviral therapy.

A 58-year-old man, who was under treatment for urticaria with emedastin fumarate for seven days, was admitted to our hospital because of jaundice. On admission, laboratory data showed the cholestatic type of liver dysfunction, AST 106 U/1, ALT 274 U/1, T-Bil 6.8 mg/dl, γ-GTP 857IU/1, and ALP 807IU/1. Anti-mitochondrial antibody (AMA) was positive with titer of 1: 80, whereas anti-pyruvate dehydrogenase (PDH) antibody was negative. Histologically, mild lymphocytic infiltration in portal area was noted. There was no fibrosis or cholangitis. A lymphocyte stimulation test for emedastin fumarate was positive and the diagnosis of drug-induced liver injury was established. Administration of the drug was immediately withheld followed by an immediate improvement in the most of the liver function tests, whereas both AMA and γ-GTP were constantly abnormal for the following two years. Anti-PDH antibody was still negative. The second biopsy of the liver showed minimal expansion of the portal area with fibrosis and mild lymphocytic infiltration. Pseudo-ductular formation and vanished bile ducts were also confirmed although no granulomas were found. These findings were atypical for primary biliary cirrhosis. This seems to be a rare case of drug-induced liver injury with long-standing anti-mitochondrial antibody without primary biliary cirrhosis as an underlying disease.

Nosocomial infection management is one of the most important subjects in terms of risk management in a hospital. To achieve the nosocomial infection management appropriately, both public relations and information gathering are important. When it comes to publicity, it is desirable that information is offered quickly and efficiently and the personnel are able to access the information easily anytime and wherever they are. As for information gathering, it is also important to collect the information concerning the nosocomial infection promptly, and to tell it quickly to infection management persons including infection control team members. The infection control committee of our hospital has engaged in both publicity and information gathering by using the committee web site established in the LAN of the hospital since January 2004. The web site carries notifications, organization chart, list of committee members, various manuals, guidance of educational activities, infection management, etc. It is also used for questions and answers, and gathering information concerning nosocomial infection. The number of times the web site was accessed was about 200 every month, and was considerable at night and on holidays. This method of using the web site seems to be useful to promote nosocomial infection management.

We treated two patients with rheumatoid arthritis (RA) who demonstrated different signs from the perspective of traditional medicine. The first case was a 73-year-old woman. In 1977, she consulted a nearby hospital due to bilateral knee joint pain. Her condition was diagnosed as RA. In 1984, she consulted our department for Stage IV and Class III disease. She was treated with Keishi-ni-eppi-itto-ka-ryojutsubu-kagen, and her condition stabilized. In 1994, she received total replacement of the bilateral knee joints. Her ADL increased, but pain at her bilateral wrist, elbow, shoulder and ankle joints persisted. Although she was treated with Yokuininto, as well as bucillamine and salazosulfapyridine, arthralgia persisted. In 1996, her condition was as follows: general malaise, pain at the bilateral shoulder and elbow joints, severe deformity at the wrist joints, dry skin and slender limbs. She walked with a cane. Therefore, we changed the formula from Keishi-shakuyaku-chimoto to Daibofu-to. Thereafter, her symptoms significantly decreased. The second case was a 50-year-old woman. In 1994, she suffered from pain in the right hand, bilateral feet and knee joints. Her condition was diagnosed as RA at a local hospital. In 1996, polyarthralgia increased and she consulted the department of orthopaedic surgery in our hospital. She was administrated bucillamine, but it was discontinued due to eruptions. Then she consulted our department. She was first treated with Keishi-ni-eppi-itto-ka-ryojutsubu, and then with Yokuininto, which did not change her symptoms. Therefore, we tried several DMARDs; however, her condition worsened. In June 2000, her laboratory data were as follows: RF 860U/ml, ESR 72mm/hr, CRP 4.0mg/dl. Although she complained of pain at the bilateral wrist, elbow and ankle joints, there was no deformity in the bilateral wrist or finger joints of either hand. She was a medium-sized person, and without dry skin or edema at the limbs. The administration of Daibofu-to improved her symptoms as well as laboratory data after 3 months of treatment.
The clinical signs of case 1 were in accordance with the traditional indications for Daibofu-to. In contrast, those of case 2 differed from these indications with regard to blood-deficiency, since there was no dry skin, change in the nail, dizziness or deformity of the joints. These observations suggest that a subset of patients with RA, who have poor deficiency of blood or Ki, may be another population that can be successfully treated with Daibofu-to.

The whole spectrum of patients infected with hepatitis C virus (HCV) who visited hospitals has not been fully clarified. It is also unknown whether such patients have visited the hospitals regularly thereafter for a long period. We studied 844 consecutive patients with liver diseases who visited our outpatient clinic located in the southern region of Ibaraki Prefecture. Five hundred eighty-three patients were HCV-infected. Among them, three patients were HBsAg-positive and another patient was IgM anti-HAV positive. Thus, 579 patients (68.6%) were considered to have HCV solely as a hepatotropic virus.Of these HCV patients, 60 were asymptomatic carriers and 15 others were unclassified because of the absence of either biopsy or imaging test records of the liver. As to the rest of the HCV patients, acute hepatitis was diagnosed in one patients, chronic hepatitis in 332 patients, cirrhosis in 130 patients and cancer of the liver in 41 patients.About half of the patients undergoing liver biopsy showed F1 in the degree of liver fibrosis. The rate of virological response to interferon mono-therapy in patients infected with genotype 2 was worse than the national average. The poor response was considered to be due to high viral load. It was suggested that the distribution of patients with each genotype was uneven in this region. After five years, the rate of patients still visiting our clinic were 68.1% for those with chronic hepatitis, and 50% for the healthy carriers. We deemed that it was important to clarify whether patients not visiting our clinic are followed up closely in other hospitals.

Effects of 38°C 30-minute bathing on hemostatic function and autonomic nervous function were studied in 15 48-to-72-year-old patients with cerebral infarction. Blood samples were collected three times: immediately before the bathing, at the end of 30 minutes of bathing, and 30 minutes after the bathing. Hematocrit values and fibrinogen concentrations decreased during bathing and returned to the pre-bathing levels 30 minutes after bathing. This indicates that bathing caused hemodilution due to the fluid shift. During bathing, noradrenaline decreased at a rate significantly higher than that of hemodilution while the sympathetic nervous function, which was evaluated by spectral analysis of sequential variation in arterial blood pressure, was not suppressed. The autonomic nervous system seemed to be inactive in these patients. Coagulation time (PT and APTT) and platelet factor (β-TG and PF4) showed few changes. In the fibrinolytic system, however, tissue plasminogen activator (t-PA) antigen levels increased and plasminogen activator inhibitor type-1 (PAI-1) levels decreased after 30 minutes of bathing. This suggests that fibrinolytic activity was enhanced by 38°C bathing for 30 minutes. Thus, subthermal bathing with comfort may be useful in preventing cerebral infarction.

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.

We encountered a case of far advanced hepatomas involving the lungs and portal veins. The patient was a 38-year-old woman. Chemoembolization had transient effects. Cachexia occurred. After repeated episodes of upper gastrointestinal bleeding, she died. An autopsy revealed a deep gastric ulcer to which a nodule of the hepatocellular carcinoma adhered. Histopathologically, the infiltration of the hepatoma was not evident. These findings suggested that circulatory distarbances of the gastric wall due to the adhesion of the growing hematoma had caused the ulceration.

Purpose: To report a case of successful treatment using gabapentin against hot flashes due to LH-RH agonist in a patient with advanced prostate cancer. Case summary: A male patient in his seventies with advanced prostate cancer had hot flashes due to LH-RH agonist therapy. The patient began to notice hot flashes within a few months after starting hormone treatment. Oral gabapentin was administered at a starting dose of 400mg/day and was gradually escalated to 1,200mg/day. Within 7 days of administration, the patient achieved a partial improvement of his symptoms. After 17 days of gabapentin therapy, the hot flashes significantly improved. While the patient was taking a maintenance dose of 1,200mg/day, he remained to be asymptomatic. Conclusion: There are only a few reports (none in Japan) that show effectiveness of gabapentin against hot flashes due to hormone treatment in male patients with prostate cancer. Although the mechanism of the hot flash-relieving effect of gabapentin is not fully understood, this case report indicates that gabapentin may help treating patients suffering from intractable hot flashes.
