Three cases of unexpected clinical course of ruptured aortic aneurysm have been presented in patients of their 7th decade life. All of them had arterial hypertension. Signs and symptoms on admission to hospital (dysphagia, chest and interscapular pain, hematemesis, abdominal pain, elevated body temperature and diminished exercise tolerance) were non-specific of aortic aneurysm, suggesting other disease. Dramatic clinical course with hypovolemic shock in two cases led to death. One of them refused surgery. In the third one, in spite of blood effusions to pleural cavity, pericardial sac and mediastinum, effective hypotensive therapy with a preservation of the slow heart rate and fluid evacuation from pericardial sac, gave the opportunity to perform elective surgery. Aortic dissection often presents an atypical course and when suspected, all available imaging technics including computed tomography and nuclear magnetic resonance must be used.

A 61-year-old woman was admitted to the hospital on September 18, 1991 because of left hemiparesis, dysphagia, and dysarthria since five days before. She was formerly pointed out diabetes mellitus and hypertension, but she did not receive any treatment. The MRI showed a high signal area in the right paramedian portion of the upper pons on T2 weighted image and proton image. The angiography showed that persistent primitive proatlantal artery originated from the left internal carotid artery and joined to the horizontal portion of the left vertebral artery. The image of carotid-vertebrobasilar system and proatlantal artery showed so severely arteriosclerotic. This is the first report of brainstem infarction with persistent primitive proatlantal artery. In this case, the pontine infarction was thought to occur on the basis of the arteriosclerosis of blood vessels and change of blood flow of carotid-vertebrobasilar system due to persistent primitive proatlantal artery.

We describe the clinical course of two cases of envenoming by the many-banded krait (Bungarus multicinctus). A man developed generalized paralysis and respiratory failure with transient hypertension. Nerve conduction studies revealed normal motor and sensory conduction velocities with reduced motor unit action potential amplitudes consistent with neuromuscular blockade. He showed a slight transient response to the banded krait (B. fasciatus) antivenom but required ventilatory support for 8 days. After the fourth day, there was some response to treatment with anticholinesterase. Another man developed diplopia, dysphagia and leg weakness but recovered spontaneously after 48 hours.

We report a patient with medial medullary infarction who showed deep sensory impairment as his prominent neurological manifestation. A 54-year-old man with a history of hypertension was admitted to our hospital with numbness of the bilateral upper and lower extremities, followed by dysarthria and right hemiparesis. Physical examination revealed no abnormalities except for high blood pressure. He hiccuped continuously. On neurological examination, he exhibited dysarthria, mild dysphagia and right hemiparesis without facial or lingual paresis. Sensitivity to light touch and pinprick was normal, but sensitivity to vibration and joint position was severely decreased in the bilateral upper and lower extremities, predominantly in the lower extremities and on the right side in the upper extremities. He had been treated with antiedema agents and thromboxane synthetase inhibitor. His hiccups stopped within two weeks, and his right hemiparesis gradually improved within one month. However, his deep sensory impairments remained prominent. Blood examinations disclosed positive lupus anticoagulant. MRI showed bilateral infarction at the medial portion of the upper medulla oblongata, extending to both pyramids, especially on the left. Somatosensory evoked potentials (SEP) after median nerve stimulation showed P14 and the later components with prolonged latency. No SEP were recorded after posterior tibial nerve stimulation. The latency of P14 was well correlated with the severity of deep sensory impairments in the upper extremities. Neurological manifestations of our patient are not typical of medial medullary infarction, and are informative about the functional anatomy of the deep sensory tract in the medulla oblongata. We discuss the relation of the intractable hiccups to the bilateral medial medullary lesions, and emphasize the importance of lupus anticoagulant as one of the risk factors in brainstem infarction.

A 36-year-old man was admitted to Kanto Chuo Hospital because of hearing loss and dysphagia. On admission physical and neurological findings revealed obesity, hypertension, nystagmus, right hearing loss, dysarthria, and dysphagia. Routine laboratory findings disclosed leukocytosis, liver dysfunction, hypercholesterolemia, proteinuria, and glucosuria. Immunological, coagulopathic, and endocrinological findings, electrocardiogram, echocardiogram, and brain CT scan were unremarkable. He was diagnosed as brainstem infarction, and then conservative therapies were begun. Seven hours after admission, he suddenly fell into coma and apneutic state, requiring artificial ventilation. The next day he was fully conscious, but could'nt make any voluntary movements except for vertical eye movements, suggesting locked-in syndrome (LIS). Brain MRI showed infarction of pons, medulla oblongata, and right cerebellum. Cerebral angiography revealed hypoplasia of bilateral vertebral arteries, a persistence of right primitive trigeminal artery (PTA), and retrograde blood flow of basilar artery from the PTA. Then he made a rapid recovery, and on 80th day he was discharged only with right hearing disturbance and mild left cerebellar sign. We speculated that hypoplasia of the bilateral vertebral arteries caused the brain infarction, and that back flow of the basilar artery from the PTA, in part, contributed to the early recovery from the LIS.

Clinical features of the anterior inferior cerebellar artery (AICA) territory infarcts were investigated in ten patients, ranging in age from 38 to 76 years. In all patients, there were MR images of infarction located in the area supplied by the AICA. The lesion was on the left side in 6 patients and right side in 4. The lesion of brain stem including the middle cerebellar peduncle was found in 7 patients and that extended to the cerebellum was in 3 patients. The main ipsilateral neurological signs were the VII and VIII cranial nerves palsy and cerebellar ataxia. The V and VI cranial nerves palsy. Horner's syndrome, and dysphagia were also present. The main contralateral sign was superficial sensory disturbance, but no hemiplegia. The underlying pathology included chiefly hyperlipidemia, hypertension, and diabetes mellitus. Cerebral angiography was performed in 8 patients, most of which was observed severe arteriosclerosis suggesting poor hemodynamics in the vertebral and basilar arteries. The prognosis was relatively good, but the VII, VIII, and V cranial nerves palsy and contralateral superficial sensory disturbance remained as the sequelae. As mentioned above, there were various neurological findings and MR images in AICA territory infarcts. Especially there were some patients whose lesion extended to the upper medulla and neurological findings were similar to the Wallenberg syndrome. It is important that one investigates not only axial slices but also coronal slices of MR image to estimate the extension of AICA territory infarct.

Gastroesophageal reflux disease (GERD) is a frequent illness, sometimes causing disabling symptoms and/or permanent oesophageal lesions. Etiology is multifactorial and not completely defined. Therapy is medical at first step, surgical indication is reserved to those patients with less compliance for medical therapy, unsuccessful medical therapy or reflux related complications. Different surgical techniques have been suggested for treatment of GERD, like Nissen, Rossetti or Toupet fundoplication. During the last decade laparoscopy has been proposed as a less invasive approach when surgery is indicated. From 1995 to the first months of 1999, 42 pts (28 females, 14 males, mean age 53.7 years), were operated on. Diagnosis and surgical indication were confirmed preoperatively by barium X-rays, endoscopy and 24 hrs-Ph-manometry. Hiatal hernia was demonstrated in 37 cases (88%), I or II grade esophagitis in 16 and III grade in 2; 1 patient had Barrett oesophagus. 37 pts were operated on by laparoscopic Nissen fundoplication, 5 patients had a Toupet operation. Mortality and conversion rate were 0. Complications occurred in 3 patients: 1 intraoperative pneumothorax, 1 acute cardiac ischemia in a patient with known hypertension, 1 permanent dysphagia successfully treated by endoscopic dilatation. Mean postoperative hospital stay was 6.1 days. Mean follow up was 9 months (3-48) in 100% of cases. Despite the fact that few patients were operated on by using this new less invasive approach, results are encouraging with no mortality, less morbidity and great advantages for patients.

Paragangliomas are rare neoplasms of neural crest origin arising in the chromaffin (pheochromocytoma) and chemoreceptor (chemodectoma) tissues. Only a few cases of paragangliomas have been reported in the heart. Most of the cardiac paragangliomas are located in, or adjacent to, the left atrium. The biological activity indicative of catecholamine production has rarely been shown in cardiac paragangliomas. Patients with cardiac paragangliomas may present with hypertension, or with various obstructive or compressive symptoms, depending on the location of the tumour. A left atrial paraganglioma compressing the esophagus causing dysphagia is presented. A 37-year-old female patient underwent work-up for dysphagia to solids. Transesophageal echocardiography showed the presence of a large mass in the dilated left atrium. The tumour was removed completely intact and was a benign noncatecholamine-secreting paraganglioma. The patient's dysphagia was relieved. The clinical perspectives of cardiac paraganglioma and cardiac dysphagia are discussed.

This is a retrospective study of 378 consecutive stroke patients who were referred between June 1994 and June 1997 for videofluorographic study of oropharyngeal swallow. Patients who had radiation therapy, brain tumor, brain surgery, head and/or spinal cord trauma, oral-pharyngeal disease or surgery, or other neurologic diseases in addition to the stroke were excluded from the study. Patients were assigned to two groups: one with pneumonia and one without pneumonia. One hundred one patients were included in the pneumonia group, and 277 patients were included in the nonpneumonia group. Within the pneumonia group, patients were assigned to an acute pneumonia group (pneumonia within 6 months poststroke) and a chronic pneumonia group (pneumonia more than 6 months poststroke). Variables examined in the study included patients' medical history and the findings from the videofluorographic studies. Pearson chi-square analysis was used to identify those variables that were significantly different between the pneumonia and nonpneumonia patient groups and between the acute and chronic pneumonia groups. Results showed that stroke patients who developed pneumonia had a significantly higher incidence of multiple-location and unspecified lesion strokes, chronic airway disease in their medical history, and aspiration during the videofluorographic studies when compared with patients who did not develop pneumonia. Within the pneumonia group, the acute pneumonia group was found to have a significantly higher incidence of hypertension and diabetes in their medical history and a significantly higher incidence of aspiration and reduced laryngeal elevation during the videofluorographic studies. Between 48% and 55% of all stroke patients in the study aspirated. Patients who suffered multiple strokes, brainstem stroke, or subcortical stroke had the greatest frequency of aspiration.

The case of an 83-year-old woman with a history of hypertension, valvular heart disease, atrial fibrillation, and cardiomegaly is presented. The patient also had progressive hoarseness of her voice and intermittent dysphagia. Ear, nose, and throat examination revealed left vocal cord paralysis. Echocardiography revealed severely dilated left (LA) and right atria (RA), moderate mitral regurgitation, severe tricuspid regurgitation, and prolapse of both these valves. A review of literature of Ortner's or cardiovocal syndrome is presented. Ortner's syndrome due to mitral valve prolapse has not been reported previously.
