A case of systemic lupus erythematosus presenting with an acute abdomen: successful treatment with steroid.

Abdominal pain continues to pose diagnostic challenges for emergency clinicians. A 56-year-old Japanese woman was referred to our hospital due to severe abdominal pain which presented as occasional epigastric pain five months before and intermittent abdominal pain. She had a past history of ileus twice, for both of which laparotomy was performed without an alimentary tract resection.

Severe case of peripheral leukocytosis initially diagnosed as myelodysplastic syndrome/myeloproliferative neoplasm, unclassifiable, but possibly prefibrotic primary myelofibrosis.

Leukocytosis is occasionally seen in patients with presumptive but undiagnosed myeloproliferative disorders (MPD). A 74-year-old woman was admitted to our hospital for tarry stools, anemia, and marked peripheral leukocytosis of 1.4×10(5)/μL.

Cronkhite-Canada syndrome showing elevated levels of antinuclear and anticentromere antibody.

A 56-year-old female initially visited an otorhinolaryngologist because of an impaired sense of taste in September, 2010 and was referred to our facility in October, 2010. She was diagnosed with Basedow's disease for which she underwent subtotal thyroidectomy in 1984 and arthritis involving multiple joints, primarily affecting her hands. In addition, the anticentromere antibody (ACA) level was markedly high.

Primary tracheal malignant lymphoma detected during a regular checkup in an asbestos dust-exposed smoker.

Primary tracheal malignant lymphoma is a rare disease; only 30 cases have been reported to date. A 73-year-old Japanese man with a history of asbestos exposure was undergoing biannual chest computed tomography (CT) twice a year as a routine procedure for those previously exposed to asbestos. He had been smoking since the age of 32.

Two cases of acute erythroid leukemia presenting with marked macrocytic anemia, reticulocytosis and hemolysis.

Case 1. The laboratory findings of a hematological analysis of a 53-year-old woman with palpitations and dyspnea revealed the following: red blood cell (RBC) count: 9.4×10(5)/μL with 60.

A case of traumatic intracranial vertebral artery injury presenting with life-threatening symptoms.

Traumatic intracranial vertebral artery injury is a relatively rare but potentially fatal disease. We present a case of a 63-year-old man who presented with sudden onset of loss of consciousness after hitting his head. After immediate resuscitation, he showed quadriplegia and absence of spontaneous breathing.

[A relapse of small-cell lung cancer ten years after concomitant chemoradiotherapy followed by high-dose chemotherapy with autologous peripheral blood stem cell transfusion].

A 57-year-old man had limited-disease small cell lung cancer in the left lower lobe of the lung. He was treated with chemotherapy with concurrent accelerated hyperfractionated thoracic radiation, followed by high-dose chemotherapy with autologous peripheral blood stem cell transplantation. He had obtained a complete response for 10 years until the tumor in the left lower lobe was detected by positron emission tomography.

Incidence and risk factors of hospital falls on long-term care wards in Japan.

Rationale, Aims And Objective: Falls among hospitalized patients are an important patient safety issue. In particular, the incidence of falls and risk of related injuries among the elderly are particularly high. Because the epidemiology of falls is not well scrutinized in Japanese long-term care wards, we evaluated the incidence and risk factors of falls in this setting.

Systematic review and metaanalysis: urinary antigen tests for Legionellosis.

Background: Urinary antigen assays offer simplicity and rapidity in diagnosing Legionnaires' disease, though studies report a range of sensitivities. We conducted a systematic review to assess the test characteristics of Legionella urinary antigen.

Methods: We searched Medline, Excerpta Medica Database, and bibliographies of retrieved articles.

Effects of risedronate or alfacalcidol on bone mineral density, bone turnover, back pain, and fractures in Japanese men with primary osteoporosis: results of a two-year strict observational study.

Although osteoporosis in men is already a major public health problem, there is still a dearth of data about the effects of risedronate in male osteoporosis, especially in Japanese with primary osteoporosis. Therefore, the objective of our study was to investigate the effects of risedronate on bone mineral density (BMD), bone turnover, back pain, and fractures in these patients prospectively for two years (at baseline, three months, six months, twelve months, and twenty-four months) both longitudinally and compared with those of alfacalcidol. The subjects enrolled for this study were 66 Japanese male patients with untreated primary osteoporosis (mean age 63.

The first imported case of rabies into Japan in 36 years: a forgotten life-threatening disease.

A domestic case of rabies has not been reported in Japan since 1957. The last case of rabies reported in Japan was an imported case from Nepal in 1970. We recently experienced a new case imported from the Philippines, the first case in Japan in 36 years.

Barriers to vaccination among Japanese medical students: focus group interviews.

Background: To date, medical schools and clinical training hospitals in Japan that require students to show immunity for measles, mumps, rubella, varicella (chickenpox), and hepatitis B prior to the commencement of residency are limited.

Methods: This qualitative study used focus group interviews to elucidate why medical students do not undergo vaccination. A total of three groups were identified and interviewed: group A (two men, three women), group B (two men, two women), group C (three men, two women).

Efficacy of risedronate in Japanese male patients with primary osteoporosis.

Objective: Although osteoporosis in men previously was relatively neglected, bisphosphonates have been strongly suggested as potent therapeutic agents. However, there are few studies on the effects of risedronate in male osteoporosis, especially in Japanese with primary osteoporosis. The aim of our study was to prospectively evaluate the effects of risedronate on bone mineral density (BMD) and bone turnover in Japanese male patients.

Three-month changes in bone turnover markers and bone mineral density response to raloxifene in Japanese postmenopausal women with osteoporosis.

It has been well established that raloxifene (RLX) improves bone turnover, increases bone mineral density (BMD), and reduces the risk of fractures. However, it remains obscure how to monitor the therapeutic effects of RLX, while numerous clinical trials for other antiresorptive agents have suggested that greater short-term reductions of bone turnover markers (BTMs) can predict greater increases in BMD and greater reduction in risk of future fractures. The purpose of this study was to investigate associations between short-term reductions of BTMs and subsequent changes of BMD after 1-year treatment with RLX.

Efficacy of combined treatment with raloxifene and alfacalcidol on bone density and biochemical markers of bone turnover in postmenopausal osteoporosis.

Because both raloxifene (RLX) and alfacalcidol (ALF) have been established as therapeutic agents for osteoporosis, it is tempting to speculate that the combination therapy of RLX and ALF might provide benefits over that of either one alone. However, the efficacy of the combination therapy has not been reported yet. The purpose of this study was thus to assess the efficacy of the combination therapy on bone mineral density (BMD) and bone turnover in patients with postmenopausal osteoporosis.

Increased bone turnover in patients with hypercholesterolemia.

Osteoporosis has been linked with arteriosclerotic vascular diseases, suggesting that hypercholesterolemia or dyslipidemia may be a common pathogenetic factor underlying these diseases. However, little is known about the relationship between osteoporosis and hypercholesterolemia. The purpose of this study was, therefore, to investigate the effects of hypercholesterolemia upon bone metabolism, by measuring bone turnover markers in hypercholesterolemic patients.

Association between baseline values of bone turnover markers and bone mineral density and their response to raloxifene treatment in Japanese postmenopausal women with osteoporosis.

It has been well established that raloxifene improves bone turnover, increases bone mineral density (BMD), and reduces the risk of fractures. However, it remains obscure which patients are more likely to respond to treatment with raloxifene in patients with postmenopausal osteoporosis. The purpose of this study was to investigate associations between baseline values of BMD and bone turnover markers (BTMs) and changes of those values after 1-year treatment with raloxifene.

Short-term effects of pitavastatin on biochemical markers of bone turnover in patients with hypercholesterolemia.

Object: No consensus has been reached whether clinical use of statins has beneficial effects on bone health, partly due to lower statin concentrations because of first-pass metabolism by the liver. We thus evaluated the effects of pitavastatin, which does not undergo first-pass metabolism, on bone metabolism.

Methods: According to the therapeutic regimen, the subjects were divided into two groups (group A, 66 with pitavastatin; group B, 35 without pitavastatin).

Clinical significance of 1-year treatment with raloxifene on bone and lipid metabolism in Japanese postmenopausal women with osteoporosis.

It has been well established that raloxifene (RLX) has beneficial effects on bone primarily in Caucasian women. However, to date, there is a dearth of data for Japanese postmenopausal women. In this study, we prospectively evaluated the effects of RLX on bone and lipid metabolism in fifty Japanese postmenopausal patients with untreated osteoporosis.

Short-term effects of atorvastatin on bone turnover in male patients with hypercholesterolemia.

No consensus has been reached on whether the 3-hydroxy 3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, known as statins, have beneficial effects on bone health. The purpose of our study was to evaluate the effects of atorvastatin on bone metabolism by means of measuring bone turnover markers in male patients with hypercholesterolemia both at diagnosis and prospectively after 3 months of treatment. Twenty-two Japanese male patients (mean age 62.

Determinants of cisplatin and irinotecan activities in human lung adenocarcinoma cells: evidence of cisplatin accumulation and topoisomerase I activity.

To elucidate the sensitivity of adenocarcinoma of the lung to cisplatin and irinotecan, intracellular glutathione (GSH) and glutathione S-transferase (GST)-pi concentrations and topoisomerase (topo) I activity were investigated using six adenocarcinoma cell lines. The antiproliferative activity was determined by MTT assay in terms of inhibition concentration (IC50) values. The IC50 values to cisplatin were not correlated with the amounts of intracellular GSH or GST-pi, but with intracellular accumulation of platinum (r = -0.

Additional effect of low iron diet on iron reduction therapy by phlebotomy for chronic hepatitis C.

Background/aims: Iron-induced oxidative stress plays an important role in the pathogenesis of chronic hepatitis C. Both phlebotomy for removing body iron stores and low iron diet for minimizing portal iron supply to the liver have been shown to improve serum transaminase levels in patients with the disease. However, the cooperative effects of phlebotomy and low iron diet have not yet been elucidated in detail.
