    Subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) are the 2 forms of desensitization for allergic diseases which are used internationally. Despite the lack of sufficient evidence of the mechanism, SCIT has been used in Japan. When SCIT is performed appropriately, it is effective for allergic rhinitis, as supported by high-level evidence, including the results of meta-analysis. However, its use in Japan has not become widespread due to various problems, including the risk of anaphylaxis. Therefore, attention is being focused on SLIT because it is easier to perform but may be similarly effective and has been extensively discussed and evaluated internationally. Comparison of SCIT and SLIT can only be done with some allergen, which has also been discussed extenesively. Many patients and physicians would welcome the use of SLIT in Japan, and its first use against pollinosis due to Japanese cedar pollen is planned for 2014.

    Objective: The objective of this study was to explore factors influencing the accuracy of transvaginal digital examination for determining fetal head position during the first stage of labor.
    Materials and Methods: Fetal head position was assessed in 87 women in the first stage of labor at term with normal singleton cephalic presentation. Transvaginal digital examinations were performed by attending midwives and were followed immediately by transabdominal ultrasound assessments performed by a single sonographer. Accuracy was defined as agreement of the results of each examination. Multivariate logistic regression analysis was performed to determine the independent factors influencing accuracy.
    Results: In only 40.3% of patients (n = 35) were transvaginal digital examinations consistent with ultrasound assessments. Multivariate logistic regression analysis showed that the accuracy of digital examinations was significantly associated with cervical dilatation more than 7 cm (odds ratio, 3.01; 95% confidence interval [CI], 1.03-9.4), birth weight less than 2,500 g (odds ratio, 8.68; 95% CI, 1.08-86.28), and the anterior occiput position group (odds ratio, 4.73; 95% CI, 1.76-13.49).
    Conclusions: The present study demonstrates that transvaginal digital examination is less accurate than ultrasonography for determining fetal head position during the first stage of labor. The results suggest that ultrasound assessments should be routinely performed in patients with a cervical dilatation less than 7 cm, an estimated fetal body weight more than 2,500 g, the occiput posterior position, or the occiput transverse position.

    Background: Atrial natriuretic peptide (ANP) plays important roles in the regulation of cardiovascular and renal homeostasis. Furthermore, several studies have shown that ANP may have anti-inflammatory activities. We hypothesized that ANP may alleviate cardiovascular and/or metabolic disorders in rats with lipopolysaccharide (LPS)-induced endotoxemia.
    Methods: In rats anesthetized with pentobarbital, LPS was injected and ANP was continuously infused at 0.15 μg/kg/min. Mean arterial pressure and pulse rate were monitored hourly, and arterial blood gases were analyzed before LPS injection and at 1, 4, and 6 hours after LPS injection. The expression in the rat left ventricle of mRNAs encoding nitric oxide synthase 2 and 3 (iNOS, eNOS), heme oxygenase 1 and 2 (HO-1, 2), tumor necrosis factor α (TNFα), and interleukin (IL)-1β was measured with the real-time reverse transcriptase-polymerase chain reaction.
    Results: LPS increased the expression of TNFα, IL-1β, iNOS, and HO-1, which was inhibited by infusion of ANP. Furthermore, the LPS-induced decrease in mean arterial pressure was attenuated, and the acid-base imbalance caused by increased lactate production was improved 6 hours after the administration of ANP.
    Conclusions: Our results suggest that continuous infusion of ANP counteracts the cardiovascular and metabolic disorders associated with endotoxemia, possibly via anti-inflammatory mechanisms.

    Introduction: Peritonitis remains a serious risk associated with continuous ambulatory peritoneal dialysis (CAPD), although better patient education programs and such technological advances as improved automated connecting devices have greatly decreased its incidence over the past 20 years. The automated devices have a good resistance to contamination, but they rely on an external electrical power source and are not easily portable. There has, therefore, been a need for a highly sterile nonelectric manual connecting device to complement the automated devices already in use. Such a manual device has recently been developed. We compared the level of sterility after touch contamination in this new device with levels in 2 other connecting devices: a conventional device with a manual cap (JMS Co. Ltd., Hiroshima, Japan), and a powered total containment device (JMS Co. Ltd.).
    Method: Five bacteria frequently causing CAPD-related peritonitis (Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans) were separately applied to the tip of each connecting device, and peritoneal washing fluid was injected as in a routine exchange. We used a membrane filter method to determine whether the route had been contaminated by the washing fluid.
    Results: In the conventional device with a manual cap, 3 to 4 colony-forming units (CFUs) of S. aureus were detected in 2 of 10 drainage samples, 8 CFUs of E. coli in 1 of 10 drainage samples, and 1 CFU of E. coli in the injection fluid. In contrast, no contamination was detected in the automated connecting device or the new manual cap device.
    Conclusion: This study confirmed that the new device has a risk of touch contamination lower than that of the conventional manual cap device and equal to that of the automated device. Being easily portable and not reliant on an external power source, the new device should be useful in various situations.

    Objective: To evaluate clinical features of assisted reproductive technology (ART) patients with pregnancy-induced hypertension (PIH) compared to spontaneously conceived PIH patients.
    Methods: We retrospectively compared PIH incidence, maternal outcomes, and neonatal outcomes among these patients.
    Results: Preeclampsia, cesarean rate, and massive maternal bleeding were significantly more common in the ART group. Neonatal outcomes showed no significant difference between the groups. Multiple regression analysis revealed ART as an independent risk factor for preeclampsia. However, higher cesarean rate and massive bleeding were mainly associated with multiple pregnancy.
    Conclusion: ART patients with PIH had an increased incidence of preeclampsia, cesarean delivery, and massive maternal hemorrhage.

    Lessons learned from the Great Hanshin-Awaji earthquake of 1995 underscored the necessity of establishing Disaster Medical Assistance Teams (DMATs) in Japan, and in 2005, the Japanese government's Central Disaster Prevention Council revised its Basic Disaster Management Plan to include full deployment of DMATs in disaster areas. Defining a DMAT as a trained, mobile, self-contained medical team that can act in the acute phase of a disaster (48 to 72 hours after its occurrence) to provide medical treatment in the devastated area, the revised plan called for the training of DMAT personnel for rapid deployment to any area of the country hit by a disaster. This paper presents descriptive data on the number and types of missions carried out by Japan DMAT (J-DMAT) in its first 5 years, and clarifies how J-DMAT differs from its counterpart in the United States (US-DMAT). The DMAT that the present authors belong to has been deployed for 2 natural disasters and 1 man-made disaster, and the operations carried out during these deployments are analyzed. Reports on J-DMAT activities published from 2004 through 2009 by the Japanese Association for Disaster Medicine are also included in the analysis. After training courses for J-DMAT personnel started in fiscal 2004, J-DMATs were deployed for 8 disasters in a period of 4 years. Five of these were natural disasters, and 3 man-made. Of the 5 natural disasters, 3 were earthquakes, and of the 3 man-made disasters, 2 were derailment accidents. Unlike in the United States, where hurricanes and floods account for the greatest number of DMAT deployments, earthquakes cause the largest number of disasters in Japan. Because Japan is small in comparison with the US (Japan has about 1/25 the land area of the US), most J-DMATs head for devastated areas by car from their respective hospitals. This is one reason why J-DMATs are smaller and more agile than US-DMATs. Another difference is that J-DMATs' activities following earthquakes involve providing treatment in confined spaces, triage, and stabilization of injuries: these services are required in the acute phase of a disaster, but the critical period is over in a much shorter time than in the case of water-related disasters. In response the kind of man-made disasters that occur in Japan-mainly transportation accidents, and occasional cases of random street violence-J-DMATs need to be deployed as soon as possible to provide medical services at the scene at the critical stage of the disaster. This means that J-DMATs have to be compact. The fact that J-DMATs are smaller and more agile than US-DMATs is a result of the types of disaster that hit Japan and the relatively small size of the country.

    A sacral pressure ulcer developed in a patient hospitalized for cerebral infarction. Each time necrotic tissue was debrided from the ulcer, pressure hemostasis was necessary to stop the bleeding. As treatment continued, the pressure required to stop the bleeding caused the ulcer to worsen, leading to a downward spiral in the patient's condition. While trying to determine the cause of this problem, we discovered that the patient had von Willebrand disease. Medication controlled the bleeding, and the pressure ulcer began to heal at the same time. It was clear to us that conservative treatment would lead to a complete cure but that the healing process would take a long time and require continued administration of an expensive drug. We decided, therefore, to close the wound with a fasciocutaneous flap so that the patient could be quickly transferred to a rehabilitation hospital. About 1 month after surgery, epithelialization was complete, we were able to discontinue medication, and the patient was discharged. This experience demonstrates the importance of determining the cause of any deviation from the normal course of healing in pressure ulcers. It also indicates that the use of fasciocutaneous flaps, which involve little intraoperative bleeding in short surgeries, is appropriate in cases like this one.

    Budd-Chiari syndrome is characterized by hepatic venous outflow obstruction. We describe a patient with a huge caudate lobe of the liver due to Budd-Chiari syndrome. A 49-year-old woman was referred to Nippon Medical School Hospital to receive treatment for enlarged gastric varices. She had been followed up for idiopathic portal hypertension with deformity of the liver for 7 years and had undergone surgery for pharyngeal carcinoma 5 years earlier. Upper gastrointestinal endoscopy revealed solitary gastric varices without esophageal varices. Abdominal computed tomography revealed obstructions and scars of the right, middle, and left hepatic veins. The caudate lobe was enlarged, and the portal vein was displaced ventrally, without thrombus. The drainage vein of the caudate lobe, the short hepatic vein on the left side of the inferior vena cava, was dilated. The portal vein and drainage vein of segment 6 were visualized and showed no atrophy. Venography revealed no obstruction of the inferior vena cava. Budd-Chiari syndrome with solitary gastric varices was diagnosed on the basis of these findings. We performed balloon-occluded retrograde transvenous obliteration and partial splenic embolization to treat the gastric varices. The posttreatment course was uneventful, and the patient was discharged 8 days after embolization. The gastric varices shrank.

    Titration of oral or intravenous medication is the preferred method of pain management for most patients with cancer pain. However, some patients experience insufficient pain relief or considerable adverse effects from systemic opioids. For these reasons, the control of severe cancer pain continues to present a variety of challenges to clinicians. We report our experience of successfully managing cancer pain in a patient by means of long-term intrathecal administration of morphine, bupivacaine, and racemic ketamine via a patient-controlled delivery system. This therapy reduced the patient's nausea, vomiting, and somnolence, led to early hospital discharge, and increased her level of daily activity. There were no signs of motor paralysis, psychomimetic alteration, neurological dysfunction, or infection related to the intrathecal route during treatment. Intrathecal therapy is an effective treatment in terminally ill patients.

    An 80-year-old woman was admitted to our hospital with severe chest and back pains after vomiting. Computed tomography (CT) of the chest revealed left-sided pneumothorax and pleural effusion. Some food was drained from an inserted chest tube, and we diagnosed spontaneous esophageal rupture (Boerhaave's syndrome). A left thoracotomy was performed 7 hours after the onset of symptoms. A 3-cm perforation was discovered in the lateral wall of the distal esophagus. The perforation was repaired with a primary two-layered closure and covered with pericardial fat. The patient had a good postoperative course and was discharged 1 month after surgery. This case suggests the importance of early surgical treatment, even in elderly patients with spontaneous esophageal rupture.
