The conventional treatment for an epiphrenic diverticulum consists of diverticulectomy with or without myotomy via a left
thoracic approach. We describe the resection of an epiphrenic esophageal diverticulum using a laparoscopic transhiatal approach
after observing its rate of enlargement on routine chest X-rays done over a number of years. This approach eliminates the
need for thoracotomy and pleural drainage, and permits a complete laparoscopic procedure, including diverticulectomy, myotomy,
and antireflex surgery. 相似文献

occ1 is a gene whose expression is particularly abundant in neurons in the macaque primary visual cortex (V1). In the present study, we report that the expression of occ1 mRNA in the macaque neocortex can be classified into two modes. The first mode is associated with excitatory neurons distributed in the major thalamocortical recipient layers that exhibit strong cytochrome oxidase activity. This is highly prominent in V1. The second mode is associated with parvalbumin-positive GABAergic interneurons and is distributed across the macaque neocortex. In V1, monocular deprivation showed that occ1 mRNA expression in excitatory neurons was markedly dependent on afferent activity, whereas that in GABAergic interneurons was not. Cross-species comparison showed specific differences in expression. In marmosets, a strong expression was observed in V1 similarly to macaques. The occ1 mRNA expression, however, was generally weak in the mouse neocortex. In rabbit and ferret cortices, the strong expression was observed only in GABAergic interneurons. We conclude that activity-dependent occ1 mRNA expression in the excitatory neurons of V1 was caused by a novel mechanism acquired by primates after their separation from other lineages. 相似文献

AIMS: Detrusor hyperactivity with impaired contractile function (DHIC) was originally described in elderly women. It has not previously been well known whether neurological diseases cause DHIC. We investigated which neurological diseases commonly cause DHIC in our laboratory. MATERIALS AND METHODS: We searched for DHIC in our laboratory's computerized database of 1,514 case records, which included a lower urinary tract (LUT) symptom questionnaire and urodynamic study results. DHIC was defined as the presence of both (1) detrusor overactivity during the storage phase, and (2) underactive detrusor contraction during the evacuation phase. RESULTS: Two hundred and seventeen patients met the criteria for DHIC: 122 men and 95 women; mean age, 63 years. The neurological diseases that caused DHIC included Parkinsonian syndrome (18%), multiple system atrophy (18%), progressive supranuclear palsy/corticobasal degeneration (14%), multiple cerebral infarction (MCI) (12%), multiple sclerosis/acute disseminated encephalomyelitis (18%), spinal cord lesions (15%), and cervical spondylotic myelopathy (CS) (10%). CONCLUSIONS: The present study revealed that a wide spectrum of neurological disorders could cause DHIC. 相似文献

A 30-year-old man presented with an aneurysm of the left posterior inferior cerebellar artery manifesting as subarachnoid hemorrhage and cerebellar infarction. Angiography demonstrated string-of-beads sign typical of fibromuscular dysplasia (FMD) in the extracranial carotid and vertebral arteries. The aneurysm and the parent artery were successfully embolized with Guglielmi detachable coils. Severe vasospasm developed 1 week after admission, and was treated several times by selective injection of vasodilator. A new aneurysm of the left external carotid artery became evident 1 month later, whereas only slight dilation had previously been apparent. This angiographic sequence demonstrated a new arterial dissection. Despite the possibility of damage to the artery during multiple catheterizations, arterial wall changes caused by FMD appear to have been primarily responsible. This case emphasizes the need for particular care in performing vascular interventional procedures in the presence of FMD. 相似文献

OBJECTIVE: To present bladder sensory data of three common peripheral nerve lesions (e.g., distal, intermediate/focal, and proximal). METHODS: We measured first sensation (FS) and bladder capacity (BC) (not exceeding 600 ml) in 71 patients with peripheral nerve lesions: 35 diabetic neuropathy (D group), 6 post-pelvic surgery (S), and 27 cauda equina syndrome due to lumbar spondylosis (L). We excluded those with detrusor overactivity or low compliance that might affect bladder sensation. RESULTS: The mean FS was 301.7 ml (D), 271.3 ml (S), and 189.4 ml (L), with the largest being in the D group (P < 0.05); the mean BC was 495.2, 475.4, and 391.4 ml, with the largest being in the D group (P < 0.05); who commonly had less frequent toileting. The mean post-void residual volume was 106.5, 29.0, and 42.0 ml; the values tended to increase along with BC. In the D group, the mean FS in patients with skin hypoalgesia as detected by pin prick and in those without it was 407.8 and 210.0 ml. The percentage of patients with FS < 100 ml was 5.7%, 0%, and 7.4%, respectively, who commonly had urinary urgency and frequency. CONCLUSIONS: Bladder sensation is affected in diabetic neuropathy more severely than in intermediate/proximal lesions, together with somatic sensory disturbance. Bladder sensory disturbance leads to less frequent toileting, resulting in bladder over-distension and large post-void residuals. A small proportion of patients with peripheral nerve lesions develop urinary urgency, presumably reflecting irritation of the afferent nerve fibers or the urothelium. 相似文献

In this study, we have developed an implantable electronics unit (IEU) for driving an undulation pump-left ventricular assist device (UP-LVAD). The IEU consists of a pump driver, three series-connected lithium ion batteries (1800 mAh), a charger, and a transcutaneous information transmission system. These electronic subunits were encapsulated in a case (110 x approximately 80 x approximately 30 mm) made of epoxy resin. The IEU was evaluated in two animal experiments using goats implanted with the UP-LVAD. The lithium ion batteries in the IEU provided 30-min energy supply daily to the UP-LVAD. The transcutaneous information transmission system transmitted data bidirectionally between the IEU and the personal computer at the data transmission ratio of 56 kbps without any transmission error. We could obtain survival days of 27 and 28 days supporting cardiac function with the UP-LVAD system. The temperature inside the IEU case was maintained under 45 degrees C, and there was evidence of a burn on the surrounding tissue in autopsies in each experiment. Based on the results, the IEU is promising to be suitable for drive and control of an implantable UP-LVAD. 相似文献

A 45-year-old female with a complaint of dyspnea was admitted to our hospital. Computed tomography (CT) and bronchoscopy revealed a 10 mm intraluminal polypoid tumor with a smooth surface and hemorrhagic tendency located in the tracheal wall 2.0 cm distal from the vocal cords. For pathological diagnosis, airway management and hemorrhage control, tumor resection was performed using a rigid bronchoscope and neodymium yttrium aluminum garnet (Nd-YAG) laser under general anesthesia. Histologically, the tumor was diagnosed as an inflammatory myofibroblastic tumor of the trachea. Inflammatory myofibroblastic tumor is typically a benign tumor that develops in such sites as the lung, stomach, and mesentery. To the best of our knowledge, this is the first reported case of an inflammatory myofibroblastic tumor arising in the trachea. 相似文献

We report a case of a previously healthy 76-year-old male with cavitating pleomorphic carcinoma of the lung. He was admitted because of an abnormal lung shadow on chest X-ray. Computed tomography (CT) showed a well-demarcated nodular shadow within thin-walled cavity in the right upper lobe. Because the lesion was revealed as adenocarcinoma by transbronchial lung biopsy, right upper lobectomy was performed. By histopathologic examination of the resected specimen, the nodule contained a component of spindle cell features and the cavity wall was composed of adenocarcinoma. The final diagnosis was pleomorphic carcinoma. Postoperative course has been uneventful for 12 months after surgery. 相似文献
