Mamushi is a species of pit viper distributed throughout Japan excluling the Ryukyu Islands and sighted from spring to autumn. It is estimated that about ten people dies in a year. It is important in the rural medicine because a lot of people are bitten in mountains and fields. A total of 35 cases of mamushi viper bite were treated from 1999 to 2006 in our hospital. The patients were 17 men and 18 women ranging in age from 7 to 80 years old (average: 60). Local swelling and pain were manifest in all the cases. Sixteen patients had systemic symptoms, and toxic effects commonly appeared in the eyes. The blood tests revealed elevated CPK levels in 24 patients (69%). The elevation correlated to the seriousness of the clinical symptoms. In accordance with our manual for mamushi viper bites, all patients were hospitalized after incision for exclusion of the toxin. The median length of time before the worst symptoms began to subside was 3 days. The median length of hospitalization stays was 7 days. It took long before the patients fully recovered. The severity of envenomation was different from patient to patient and one case needed intensive care. The median of treatment period was 31 days. The quick and appropriate primary care for the mamushi viper bits is important to prevent serious complications.

A study was performed to investigate the effect of ingestion of two different carbohydrates immediately after exhaustive exercise on muscle glycogen restoration in rats. The carbohydrate solu-tions used were 20% maltodextrin (osmolality: 270 mOsm/kg⋅H2O) and 20% glucose (osmolality: 1370mOsm/kg·H2O) . At both 30 and 60 min after oral ingestion, the osmolality in the gastric residue was significantly higher in the group given the glucose solution than in the group given the maltodextrin solution. The concentration of serum glucose at both 30 and 60 min after oral ingestion was significantly higher in the group given maltodextrin than in the group given glucose. Compared to the group given glucose, the group given maltodextrin had significantly higher muscle glycogen contents in M. plantaris and M. gastrocnemius at both 30 and 60 min after oral ingestion. Furthermore, the muscle glycogen contents in the group given maltodextrin returned to the levels in resting control rats 60 min after oral ingestion. Thus it is concluded that ingestion of maltodextrin solution immediately after exhaustive exercise might be effective for rapid restoration of muscle glycogen.

Recently the evaluation of health-related quality of life (QOL) in cancer patients has become important in carrying out a treatment strategy. During a period between June and August 2004, we studied the QOL in 16 breast cancer patients with or without chemotherapy. The regimens of chemotherapy were EC (n=6), AT (n=1) and CMF (n=1). We made the Functional Assessment of Cancer Therapy Scale-General (FACT-G) in all patients. The patients treated without chemotherapy were superior to those with chemotherapy with respect to physical and emotional well-being (p<0.05). There were no differences in social well-being and relationship to families between the two groups. The patients treated without chemotherapy made significantly higher scores in the basic activities of daily living than those with chemotherapy (p<0.05). Compared with patients receiving chemotherapy, patients treated without chemotherapy had better quality of life (p<0.05). We concluded that it was important for us to assist in decision making about treatment and supportive care needs.

Recently, the incidence of pulmonary embolism (PE) after surgery began to increase in Japan and to prevent PE has become essentially important. During the period between July 2003 and August 2004, we placed 203 general surgical patients under our perioperative management using intermittent pneumatic compression (IPC) and compression stockings (CS). We evaluated the effect of our management on the prevention of postoperative PE in those patients. The incidence of PE, prognosis, complications, patient's complaints, cost-benefit were examined. No fatal PE occurred. One patient with low SpO2 had a chest pain and dyspnea but pulmonary scintigrams revealed no PE. Two other patients had contact dermatitis by CS and another patient using an epidural catheter suffered temporary paraplegia after heparin injection. The government has approved a fee for PE prophylaxis since April 2004. Our management using IPC and CS for PE prophylaxis after surgery proved to be an effective in reducing the risk of PE. However, we must take the atmost care in injecting heparin into patients with epidural catheters.

BACKGROUND: Listeria monocytogenes (L. monocytogenes) is a rare causative pathogen of brain abscess that is often found in immunocompromised patients. Although patients with supratentorial listerial abscesses showed a longer survival with surgical drainage, the standard therapy for patients with subtentorial lesions has not been established. CASE REPORT: We report herein a patient with supra- and subtentorial brain abscesses caused by L. monocytogenes infection. These abscesses did not respond to antibiotics, and his symptoms gradually worsened. Drainage was not indicated for subtentorial lesions, and the patient was additionally treated with hyperbaric oxygen therapy, which dramatically reduced the volume of abscesses and improved the symptoms. CONCLUSIONS: This is the first report of drastic therapy for a patient with listerial brain abscesses involving combined antibiotics and hyperbaric oxygen therapy. The findings suggest that hyperbaric oxygen therapy is a good option for treating patients with deep-seated listerial abscesses and for who surgical drainage is not indicated.

OBJECTIVE: To validate the relationship between residual walking ability and monthly care cost as well as long-term care insurance (LTCI) certification level in elderly patients after surgical treatment for hip fractures in Japan. METHODS: Elderly patients aged >75 years who underwent surgical treatment for hip fractures in our hospital were included. The preand post-surgical (6-month) walking ability and LTCI certification and the presence or absence of dementia was determined from medical records and questionnaires. Walking ability was classified into 6 levels used in our daily medical practice. Based on these data, we correlated the relationship between walking ability and the LTCI certification level. Further, based on the official statistics pertaining to the average monthly costs per person at each LTCI certification level, we evaluated the relationship between walking ability and monthly care cost. RESULTS: A total of 105 cases (mean age, 80.2 years; 16 men; 39 patients with dementia) were included. The correlation between walking ability and average monthly cost per person as well as LTCI certification level at 6 months postoperatively (r=0.58) was demonstrated. The correlation was found in both groups with and without dementia. CONCLUSION: The ability to walk reduced the cost of care in elderly patients who experienced hip fracture, regardless of the presence of dementia.

STUDY DESIGN: Controlled laboratory study. PURPOSE: This study aimed to evaluate the efficacy of platelet-rich plasma (PRP) stored at room temperature (RT), frozen, or after freeze-drying. OVERVIEW OF LITERATURE: PRP enriches tissue repair and regeneration, and is a novel treatment option for musculoskeletal pathologies. However, whether biological activity is preserved during PRP storage remains uncertain. METHODS: PRP was prepared from blood of 12 healthy human volunteers (200 mL/person) and stored using three methods: PRP was stored at RT with shaking, PRP was frozen and stored at −80℃, or PRP was freeze-dried and stored at RT. Platelet counts and growth factor content were examined immediately after preparation, as well as 2, 4, and 8 weeks after storage. Platelet activation rate was quantified by flow cytometry. RESULTS: Platelet counts were impossible to determine in many RT samples after 2 weeks, but they remained at constant levels in frozen and freeze-dried samples, even after 8 weeks of storage. Flow cytometry showed approximately 80% activation of the platelets regardless of storage conditions. Almost no growth factors were detected in the RT samples after 8 weeks, while low but significant expression was detected in the frozen and freeze-dried PRP. Over time, the mean relative concentrations of various growth factors decreased significantly or disappeared in the RT group. In the frozen group, levels were maintained for 4 weeks, but decreased significantly by 8 weeks (p <0.05). The freeze-dried group maintained baseline levels of growth factors for the entire 8-week duration. CONCLUSIONS: Freeze-drying enables PRP storage while maintaining bioactivity and efficacy for extended periods.

PURPOSE: Pain from osteoarthritis (OA) is generally classified as nociceptive (inflammatory). Animal models of knee OA have shown that sensory nerve fibers innervating the knee are significantly damaged with destruction of subchondral bone junction, and induce neuropathic pain (NP). Our objective was to examine NP in the knees of OA patients using painDETECT (an NP questionnaire) and to evaluate the relationship between NP, pain intensity, and stage of OA. MATERIALS AND METHODS: Ninety-two knee OA patients were evaluated in this study. Pain scores using Visual Analogue Scales (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), painDETECT, duration of symptoms, severity of OA using the Kellgren-Lawrence (KL) system, and amount of joint fluid were evaluated and compared using a Spearman's correlation coefficient by rank test. RESULTS: Our study identified at least 5.4% of our knee OA patients as likely to have NP and 15.2% as possibly having NP. The painDETECT score was significantly correlated with the VAS and WOMAC pain severity. Compared with the painDETECT score, there was a tendency for positive correlation with the KL grade, and tendency for negative correlation with the existence and amount of joint fluid, but these correlations were not significant. CONCLUSION: PainDETECT scores classified 5.4% of pain from knee OA as NP. NP tended to be seen in patients with less joint fluid and increased KL grade, both of which corresponded to late stages of OA. It is important to consider the existence of NP in the treatment of knee OA pain.

PURPOSE: The pathological mechanism of lumbar spinal stenosis is reduced blood flow in nerve roots and degeneration of nerve roots. Exercise and prostaglandin E1 is used for patients with peripheral arterial disease to increase capillary flow around the main artery and improve symptoms; however, the ankle-brachial index (ABI), an estimation of blood flow in the main artery in the leg, does not change after treatment. Lumbar spinal nerve roots contain somatosensory, somatomotor, and unmyelinated autonomic nerves. Improved blood flow by medication with prostaglandin E1 and decompression surgery in these spinal nerve roots may improve the function of nerve fibers innervating muscle, capillary, and main vessels in the lower leg, resulting in an increased ABI. The purpose of the study was to examine whether these treatments can improve ABI. MATERIALS AND METHODS: One hundred and seven patients who received conservative treatment such as exercise and medication (n=56) or surgical treatment (n=51) were included. Low back pain and leg pain scores, walking distance, and ABI were measured before treatment and after 3 months of conservative treatment alone or surgical treatment followed by conservative treatment. RESULTS: Low back pain, leg pain, and walking distance significantly improved after both treatments (p<0.05). ABI significantly increased in each group (p<0.05). CONCLUSION: This is the first investigation of changes in ABI after treatment in patients with lumbar spinal stenosis. Improvement of the spinal nerve roots by medication and decompression surgery may improve the supply of blood flow to the lower leg in patients with lumbar spinal stenosis.

PURPOSE: To examine the effects of conservative and surgical treatments for nocturnal leg cramps in patients with lumbar spinal stenosis (LSS). Nocturnal leg cramps is frequently observed in patients with peripheral neuropathy. However, there have been few reports on the relationship between nocturnal leg cramps and LSS, and it remains unknown whether conservative or surgical intervention has an impact on leg cramps in patients with LSS. MATERIALS AND METHODS: The subjects were 130 LSS patients with low back and leg pain. Conservative treatment such as exercise, medication, and epidural block was used in 66 patients and surgical treatment such as decompression or decompression and fusion was performed in 64 patients. Pain scores and frequency of nocturnal leg cramps were evaluated based on self-reported questionnaires completed before and 3 months after treatment. RESULTS: The severity of low back and leg pain was higher and the incidence of nocturnal leg cramps was significantly higher before treatment in the surgically treated group compared with the conservatively treated group. Pain scores improved in both groups after the intervention. The incidence of nocturnal leg cramps was significantly improved by surgical treatment (p=0.027), but not by conservative treatment (p=0.122). CONCLUSION: The findings of this prospective study indicate that the prevalence of nocturnal leg cramps is associated with LSS and severity of symptoms. Pain symptoms were improved by conservative or surgical treatment, but only surgery improved nocturnal leg cramps in patients with LSS. Thus, these results indicate that the prevalence of nocturnal leg cramps is associated with spinal nerve compression by LSS.
