We herein report on a case in which we conducted bypass surgery for occlusion of a left axillary artery aneurysm with ischemic symptoms 21 years after the contraction of Kawasaki disease and achieved symptomatic improvement. The case involved a 22-year-old man who had been suffering from Kawasaki disease since the age of one. He had been undergoing antiplatelet therapy for bilateral axillary artery aneurysms by orally taking aspirin for 20 years. He suffered from symptoms of upper limb ischemia 21 years after receiving a diagnosis of peripheral aneurysms and occlusion of a left axillary artery aneurysm upon 3DCTA. We conducted aneurysmotomy, plication, and bypass surgery between the axillary and brachial arteries via the autologous vein. Pathological examination revealed due to the formation of atheroma in the tunica intima and disarrangement of the layer structure in the tunica media : thickening of the tunica media was partially observed. His fatigue upon exertion of his left upper extremity remarkably improved following surgery. Although peripheral aneurysms associated with Kawasaki disease are rare, as seen in this case, peripheral arterial disease remains and progresses even after long periods of time. It is believed necessary to carry out long term follow-up and examine the approaches to therapy including surgery in accordance with the site and degree of the disease.

This study aimed to estimate the cost-effectiveness of pregabalin treatment for neuropathic pain.
Design:Long-term simulations based on state transition models.
Methods:We examined the cost-effectiveness of pregabalin for treatment of three common peripheral neuropathic pains, postherpetic neuralgia(PHN), painful diabetic peripheral neuropathy(DPN), and radiculopathy, using the incremental cost-effectiveness ratio(ICER). We used quality-adjusted life years(QALYs)as an index of effectiveness, and also estimated medical costs. For PHN and DPN, we constructed state transition models comprising two states, with and without pregabalin treatment, and performed 52-week simulations. The pain scores reported in Japanese phaseIII studies were used to set patients' weekly pain scores. The results of utility surveys conducted overseas were used as utility scores, while values randomly sampled from probability distributions were used to set weekly pain scores and drop-out rates. In base-case analyses, we performed 1000 1st-order Monte Carlo simulations using 1000 values randomly sampled from probability distributions, and calculated QALYs and medical costs for 52 weeks for each group. For radiculopathy, the ICER was calculated from changes in QALYs for 12 weeks reported overseas and medical costs estimated separately for the identical period.
Results:The ICERs for PHN, DPN, and radiculopathy were 1,116,886 Yen/QALY, 1,100,420 Yen/QALY, and 1,095,943 Yen/QALY, respectively, which were well below the upper limits of ICER ranges for treatments considered cost-effective. There were no cases in which ICERs obtained from scenario and sensitivity analyses differed significantly.
Conclusion:Pregabalin was shown to be cost-effective treatment for neuropathic pain.

Congenital syphilis (CS) is a public health burden in both developing and developed countries. We report two cases of CS in premature neonates with severe clinical manifestations; Patient 1 (gestational age 31 weeks, birth weight 1423 g) had disseminated idiopathic coagulation (DIC) while Patient 2 (gestational age 34 weeks and 6 days, birth weight 2299 g) had refractory syphilitic meningitis. Their mothers were single and had neither received antenatal care nor undergone syphilis screening. Both neonates were delivered via an emergency cesarean section and had birth asphyxia and transient tachypnea of newborn. Physical examination revealed massive hepatosplenomegaly. Laboratory testing of maternal and neonatal blood showed increased rapid plasma reagin (RPR) titer and positive Treponema pallidum hemagglutination assay. Diagnosis of CS was further supported by a positive IgM fluorescent treponemal antibody absorption test and large amounts of T. pallidum spirochetes detected in the placenta. Each neonate was initially treated with ampicillin and cefotaxime for early bacterial sepsis/meningitis that coexisted with CS. Patient 1 received fresh frozen plasma and antithrombin III to treat DIC. Patient 2 experienced a relapse of CS during initial antibiotic treatment, necessitating parenteral penicillin G. Treatment was effective in both neonates, as shown by reductions in RPR. Monitoring of growth and neurological development through to age 4 showed no evidence of apparent delay or complications. Without adequate antenatal care and maternal screening tests for infection, CS is difficult for non-specialists to diagnose at birth, because the clinical manifestations are similar to those of neonatal sepsis and meningitis. Ampicillin was insufficient for treating CS and penicillin G was necessary.

Ten healthy adults lying in the supine position underwent ‘painless sohri-kifu technique’, ‘Oshide only’, ‘acupuncture only’ and ‘painfull sohri-kifu technique’ on the left ‘Tai-en’ point for one minute. Instantaneous heart rate was measured with a polygraph. Statistical analysis showed that ‘sohri-kifu technique’ and it's constituent—‘Oshide only’, and ‘acupuncture only’ caused significant the decrease of heart rate. The painless sori-kifu technique was more effective than ‘Oshide only’ and ‘acupuncture only’ in decreasing the heart rate. The ‘painful sori-kifu technique’ caused no significant change of heart rate. Sticking pain seems to effective in suppressing the decrease of heart rate.

A pseudoaneurysm of the thoracic aorta after cardiac surgery is a rare complication, but can be life-threatening when it is ruptured. The pseudoaneurysm itself presents no symptoms in many cases, or may be similar to an atherosclerotic aortic aneurysm. Therefore, it is usually found incidently during imaging studies. We encountered 3 cases of pseudoaneurysm of the thoracic aorta that developed during the long-term follow-up after congenital cardiac surgery. None of the patients experienced specific symptoms associated with the pseudoaneurysm, and were diagnosed by chest roentgenograms and computed tomography. Most patients who undergo surgery for congenital heart defects as adolescents are free from medical treatment, and do not regularly see a doctor after the surgery. It is important to consider the possibility of a pseudoaneurysm in patients having a history of cardiac surgery.

Subclavian artery aneurysm (SCAA), a peripheral arterial aneurysm, is a rare entity. The surgical procedure and approach depend on the location of the aneurysm. We present a case of the endovascular therapy combined with cross axillary bypass. The patient was a 75-year-old man with a small abdominal aortic aneurysm. Multi-detector computed tomography (MDCT) revealed an intrathoracic right SCAA 38 mm in diameter. The operation was performed successfully under general anesthesia. After cross bypass of bilateral axillary artery, the orifice of the right subclavian artery was covered with a stent-graft inserted into the right common carotid artery-brachiocephalic artery and the right subclavian artery was occluded with coils distal to the aneurysm. Post operation angiogram showed complete exclusion of the SCAA and patency of the right common carotid and right vertebral artery. We thought this hybrid treatment for the intrathoracic SCAA could be a useful surgical strategy.

Aortic dissection with rupture into the right atrium is an extremely rare and rapidly fatal condition. We report the case of a 59-year-old man with a history of double valve replacement 2 years earlier at another hospital. Although the previous postoperative course had been uneventful, the patient had experienced facial edema and general fatigue for 10 days before admission to our hospital because of heart failure. The diagnosis of chronic aortic dissection with rupture into the right atrium was confirmed by intraoperative transesophageal echocardiography. At operation, we observed an aortic dissection that originated from a tear in the original aortic incision line. The fistula extended from the false lumen to the right atrium. The aortic adventitia were partially defective. The aortic dissection had ruptured and a pseudo-aneurysm had formed. We performed ascending aortic replacement and closure of the aorta-right atrium fistula under hypothermic arrest on cardiopulmonary bypass. The postoperative course was uneventful and the patient was discharged on the 17th postoperative day.

Comparative trials were undertaken using 16 types of guide-tubes of different caliber and external diamter: small caliber (1.35mm) and large cliber (1.80mm) tubes of eight types of external diameter (i. e, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5 and 6.0mm). 540 tappings was performed with a hard needle (length: 58.0mm, diameter: 0.16mm, head diameter: 1.25mm).
The result can be summarized as follows:
1. Among the six small guide-tubes with 2.5-5.0mm external diameter, the larger external diameter was, the less sticking pain was experienced.
2. The four small caliber guide-tubes with 4.5-6.0mm external diameter caused significantly less sticking pain compared with the four small caliber guide-tubes of 2.5-4.0mm and the four large guide-tubes of 4.5-6.0mm.

Herein is reported our experience of radiation therapy using a real-time tumor-tracking and gated radiotherapy (RTRT) system for inoperable pancreatic cancer. Three unresectable pancreatic cancer patients were treated with intraoperative electron beam radiation therapy, at the time of open biopsy, and postoperative external beam radiation therapy using an RTRT system with a 2.0 mm diameter gold ball implanted into the pancreas. The total BED's (alpha/beta=10) was intended to be equivalent to that of delivering 60 Gy by 2.0 Gy/fraction, while the actual dose schedules were individualized. The movement of the pancreas was analyzed based on the 3-dimensional marker positions during the RTRT. The side effects and tumor responses were evaluated. During the RTRT course, the average movement of markers in the x (left to right), y (cranial to caudal) and z (dorsal to ventral) directions were 3.0 mm (1.7- 5.2 mm), 5.2 mm (3.5 - 6.8 mm) and 3.5 mm (2.7 - 5.1 mm), respectively. During and after the course of postoperative radiation therapy, no acute side effects of RTOG grade II or higher were detected. The objective tumor responses, as evaluated by CT scans 3 months after the treatment, were 2 partial responses and no response in one patient. Using the RTRT technique the margin of treatment planning and the possible errors in target localization were reduced, and the 3-dimensional movement of the internal marker implanted in the pancreas was able to be analyzed.
