A 48-year-old man with Buerger disease and intractable finger ulcers underwent successful transplantation of autologous peripheral blood-derived mononuclear cells pretreated with erythropoietin and blood donation to activate bone marrow function. Clinical symptoms on his finger ulcers improved significantly within 1 month after mononuclear cell transplantation, however, one of the intractable ulcers reappeared 2 months later. In total three transplantations were performed. Every cell transplantation revealed similar effectiveness 1 month later, and the interval of the subsequent disappearance of finger ulcers ranged from 3–6 months. There were no adverse effects based on this new therapy. These findings suggest that autologous peripheral mononuclear cell transplantation pretreated with erythropoietin and blood donation might be a non-invasive and safe alternatives for patients with Buerger disease and intractable finger ulcers.

A 69-year-old woman had syncope and aphasia. Magnetic resonance imaging showed multiple cerebral infarctions in both hemispheres. Cardiogenic embolisms were suspected, but no arrhythmic causes were shown. Transesophageal echocardiography revealed a highly calcified mitral annulus (MAC) with a rough intraluminal surface and mild mitral regurgitation, but no thrombus or tumor in the left heart system. However, recurrent multiple cerebral embolisms occurred in spite of strict anticoagulation therapy. We speculated that spontaneous rupture of the MAC was the cause of the scattered cerebral embolisms, and we therefore planned to remove the MAC as safely as possible and to endothelialize the deficit of MAC with autologous pericardium. Operative findings revealed that the MAC in P2-P3 had ruptured longitudinally and the ostium of the left atrium was connected to the ostium of the left ventricle as an inter-atrioventricular tunnel beneath the posterior mitral annulus with a fragile calcified wall. The finding suggested that calcified particles that had peeled away from the MAC by normal heart beating resulted in the cerebral infarctions. Therefore, she underwent resection of the MAC and mitral valve replacement with reinforcement of the decalcified posterior mitral annulus between the posterior left ventricular wall and the left atrial wall using autologous pericardium, which enabled both appropriate insertion of a mechanical prosthetic valve and endothelial continuity covering the surface of the residual MAC. No systemic embolism has occurred for two and a half years after surgery. This is the first case report of cerebral embolism caused by a spontaneously ruptured MAC.

A 65-year-old woman was admitted to our hospital complaining of chest pain in 2012. Coronary computed tomography angiogram revealed left main coronary artery atresia (LMCAA) with congenital absence of the left main trunk, and LAD received several collaterals perfusing from the RCA. She was observed because her symptoms were transient. However, her dyspnea on effort gradually became worse in 2016. Treadmill exercise electrocardiography showed ST depression in II・III・aVF and V4-6. Also, echocardiography showed severe MR due to the prolapse of the anterior leaflet and moderate TR. We performed mitral valve plasty and tricuspid valve plasty, and coronary artery bypass grafting using the left internal thoracic artery to the left descending artery in March, 2017. The postoperative course was uneventful. She was discharged in good condition 14 days after operation. LMCAA is a rare coronary anomaly. There are only 53 published case reports, and a few surgical reports in adult cases. This is a rare adult case of surgical treatment of LMCAA.

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.

Pneumonia is common among elderly patients and the incidence among older adults is increasing in aging societies. If pulmonologists were to treat all cases of pneumonia, their work volume would be immense and the risk of burnout would increase. We reviewed cases of consecutive patients 70 years of age or older who were treated for pneumonia between November 2017 and October 2018 at Akita Kousei Medical Center. Of a total of 372 patients recruited for this study (214 men, mean age 85.6 years), 288 patients recovered and 84 (29.2%) died. The duration of admission differed significantly between the cardiovascular department and surgery department (p=0.03), between the renal unit of the internal medicine department and the neurosurgery department (p=0.01), and the renal unit of the internal medicine department and the surgery department (p=0.0005). Outcome was not significantly different among departments. It is crucial that pulmonologists and non-pulmonologists collaborate to treat pneumonia in old adults.
