We analyzed the questionnaires concerning sleep-wake complaints in 1,575 Parkinsonian patients and 2,509 controls of 945 office workers and 1564 seniors living at home. The questionnaire included 20 contents. The Parkinsonian patients complained of sleep-wake disturbances more frequently than the controls in initiation disturbance, frequent awakenings in night, early morning awakening, day time sleepiness, usage of sleep pills, parasomnias, restless legs symptoms, nocturnal myoclonus, snoring, apnea episodes and dyspnea in night (chi-square method). The incidences of restless legs symptoms and nocturnal myoclonus increased significantly with worsening of physical symptoms in the Parkinsonian patients (p less than 0.01).

We report an unusual neurologic complication of herpes zoster. After thoracic herpes zoster, our patient complained of severe shortness of breath as a result of myoclonus of the abdominal muscles as documented by electromyography. The myoclonus resulted in repetitive interruption of expiratory air flow, resulting in shortness of breath and a staccato speech. This case demonstrates the need to evaluate the function of all the respiratory muscles in a patient complaining of dyspnea.

Velo-pharyngo-laryngeal myoclonus, the rapid, rhythmic contraction of muscles of the pharynx and larynx, is a rare neurological manifestation of numerous disease processes affecting the cerebellum. In its most common form, palatal myoclonus, this disease frequently presents to the otolaryngologist as objective tinnitus. Impedance audiometry provides a useful means of verifying suspected palatal myoclonic activity through recorded changes in the middle ear pressure, as mediated by muscle activity at the proximal portion of the eustachian tube. A very rare case of velo-pharyngo-laryngeal myoclonic with clonic contraction of the laryngeal adductors and subsequent extrathoracic airway obstruction is presented. Tracheostomy provided immediate symptomatic relief of dyspnea.

A 64-year-old male with a history of tuberculous pleuritis at age 29 had received home oxygen therapy since age 58 because of chronic respiratory failure. He was admitted with symptoms of dyspnea at rest and myoclonus at age 62. Because CO2 narcosis occurred twice, we performed intermittent negative pressure ventilation (INPV) after short-term positive pressure ventilation with transnasal intubation. He has received INPV for 7 hours every day at his home for 20 months without acute exacerbation of respiratory failure, and his activity of daily life subsequently improved. In conclusion, INPV seems to be useful for patients with chronic hypercapnic respiratory failure due to lung disease.

We report a 61-year-old male with rapidly progressive dementia and gait disturbance. He was well until spring 1990 as a postmaster, when there was an onset of memory disturbance and mistakes in his job. In May 1990, his wife noted slurring of his speech. In August, there was an onset of gait disturbance. He fell down frequently. In October, he was seen by a neurologist, who found moderate dementia, small step gait, retropulsion, freezing, paratonic rigidity, bradykinesia and a restriction in the vertical gaze on him. His dementia and gait disturbance progressed rapidly and in May 1991, he developed fever and dyspnea and was admitted to Juntendo University Urayasu Hospital. On admission, he was chronically ill and wheezing rale was heard on both lung fields. Neurologically, he was awake but without response to the simplest examiner's command. Cranial nerves appeared intact except for a restriction in the upward gaze. His posture was opisthotonic with a decorticated posture. Marked rigidity was present in all four limbs. He could not sit or stand. Deep reflexes were diminished symmetrically. He was treated by supportive cares, however, he expired 12 days after his admission. In no time myoclonus was observed, nor PSD recorded in his EEG. Cranial CT scans revealed moderate cortical atrophy. The patient was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that he had Creutzfeld-Jakob disease despite the absence of myoclonus and PSD. Postmortem examination revealed diffuse spongy state of the cerebral hemisphere as well as striatum.(ABSTRACT TRUNCATED AT 250 WORDS)

Prediction of future suffering could improve palliative care. To identify the factors contributing to physical symptoms, a prospective study was performed on two series of hospice inpatients with cancer (n = 150 and n = 200, respectively). Physical symptoms, patients' characteristics, and tumor locations were recorded using a structured protocol on admission and throughout the clinical course. Common symptoms on admission and during the patient's course were pain (65%, 88%), general malaise (58%, 77%), anorexia (57%, 94%), constipation (33%, 71%), dyspnea (33%, 66%), nausea/vomiting (29%, 48%), cough/sputum (29%, 48%), edema (27%, 65%), fever (26%, 70%), abdominal swelling (26%, 42%), and dry mouth (25%, 61%), respectively. The mean number of symptoms was 5.7 +/- 3.0 on admission and 9.6 +/- 3.1 during the course. Factors that contributed to the symptoms were young age (pain, abdominal swelling, dry mouth), performance status (anorexia, general malaise, edema, dyspnea), brain tumor (paralysis), neoplasms of lung/pleura (dyspnea, cough/sputum, death rattle), bone metastasis (pain, paralysis), gastric/pancreas cancer (abdominal swelling), peritoneal metastasis (general malaise, edema, nausea/vomiting, abdominal swelling, dry mouth), opioids (constipation, dry mouth, myoclonus), anticholinergics (dry mouth), and antidopaminergics (myoclonus). Opioid requirement was positively correlated with the presence of bone metastasis, and negatively correlated with age and brain involvement. Additional opioids were frequently used in the final 48 hours in cases with lung/pleura neoplasms. These data suggest that terminal symptoms in cancer patients are determined by local and/or general factors. Clinicians can predict the probability of future symptoms from patients' characteristics, general condition, tumor locations, and medications.

Most terminally ill patients experience symptoms that require treatment as death approaches. The most common symptoms are pain (5% to 51%), dyspnea (28%), oral and respiratory secretions (25%), nausea and vomiting (10% to 14%), confusion (10%), myoclonus (12%), and bowel and bladder problems (over 20%). These symptoms can be well controlled in up to 90% of individuals with appropriate communication; emotional, spiritual, and social support; noninvasive clinical evaluation; and therapy focused on symptom palliation. Types of drugs that are important in symptom control include opioids, co-analgesics, anxiolytics, and anticholinergics. To be effective, these medications must be readily available for use and often need to be given by a non-oral route.

We report a 56-year-old woman with progressive gait disturbance. Her mother had Parkinson's disease with onset at age 70. She died at age 74 and the post-mortem examination confirmed the diagnosis of Lewy body positive Parkinson's disease. The patient was well until the age of 50(1995) when she noted an onset of resting tremor and difficulty of gait. She also developed delusional ideation and was admitted to a psychiatric service of another hospital, where a major tranquilizer was given. The delusion disappeared but she developed marked rigidity. The major tranquilizer was discontinued and an anticholinergic and amantadine HCl were given. She showed marked improvement to Hoehn and Yahr stage II and was discharged. In 1995, when she was 52 years of the age, she developed delusion again and a major tranquilizer was given. She developed marked parkinsonism again and became Hoehn and Yahr stage V. The major tranquilizer was discontinued and she was treated with levodopa/carbidopa, trihexyphenidyl, bromocriptine, and dops. She improved remarkably to stage II. She was admitted to our service on October 8, 1996 for drug adjustment. She was alert and not demented. She was anxious but delusion or hallucination was noted. Higher cerebral functions were intact. Cranial nerve functions were also intact except for masked face and small voice. Her posture was stooped and steps were small. She showed retropulsion and moderate bradykinesia. Resting tremor was noted in her left hand. Rigidity was noted in both legs. No cerebellar ataxia or weakness was noted. Deep tendon reflexes were within normal range and sensation was intact. Her cranial MRI revealed some atrophic changes in the putamen, in which a T 2-high signal linear lesion was seen along the lateral border of the putamen bilaterally. In addition, posterior part of the putamen showed T 2-low signal intensity change. She was treated with 1.6 mg of talipexole, 6 mg of trihexyphenidyl, and 100 mg of L-dops. She was in stage III of Hoehn and Yahr. She developed neurogenic bladder with a large amount of residual urine for which she required catheterization. She was transferred to another hospital. Despite drug adjustment, she lost response to levodopa and her parkinsonism deteriorated gradually. She also developed syncope orthostatic hypotension. In April of 1998, she developed intracerebral hemorrhage and was admitted again on April 19, 1998. She was unable to stand and showed marked akinesia and rigidity. She was in stage V of Hoehn and Yahr. Her cranial CT scan revealed bilateral high-density lesions in the posterior parietal lobes. She developed dysphagia for which she required gastrostomy. She was transferred to another hospital but her clinical condition deteriorated further. On December 22, 1999, she developed fever and dyspnea and was admitted to our service again. She developed cardial arrest at the emergency room from hypoxia. She was resuscitated; however, she was comatose with loss of brain stem reflexes. Later on she developed generalized myoclonus. She developed cardiac arrest and pronounced dead on December 28, 1999. The patient was discussed in a neurological CPC. The chief discussant arrived at the conclusion that the patient had striatonigral degeneration because of poor response to levodopa in the later course, autonomic failures, and MRI changes. Some other participants thought that the patient had a form of familial Parkinson's disease. Opinions were divided into these two possibilities. Post-mortem examination revealed that the substantia nigra showed intense neuronal loss and gliosis, however, no Lewy bodies were seen. In addition, intracytoplasmic inclusions were seen in oligodendrocytes. The putamen was markedly atrophic in its posterior part with marked gliosis and neuronal loss. The ventromedial part of the pontine nucleus also showed neuronal loss and intracytoplasmic glial inclusions. Pathologic diagnosis was multiple system atrophy. In the parietal lobe, an arteriovenous malformation with bleeding was noted. This is very unique case. Although her mother had Lewy body-positive Parkinson's disease, the patient had Lewy body-negative multiple system atrophy with a-synuclein-positive glial inclusions. Whether this is just a coincidental occurrence or the presence of a genetic load for Parkinson's disease might triggered her multiple system atrophy is an interesting question to be answered in future.

A 67-year-old man presented with dysphagia and difficulty breathing. Physical examination revealed palatal myoclonus. In this patient, the respiratory difficulty was caused by the fragmentation of breathing. Electromyographic examination of the cricothyroid muscle demonstrated rhythmic myoclonic jerks. Magnetic Resonance Imaging (MRI) yielded a pontine midline and right sided tegmental infarct. The patient responded to sodium valproate.

An 18-year-old woman was treated with neuroleptic analgesia using fentanyl, morphine, droperidol and haloperidol for general anesthesia and pain control for her knee operation. Postoperatively, she showed emotional unstableness, following dyspnea, tachycardia, fever, hyperhydrosis, muscle rigidity and myoclonus like involuntary movement. She received infusion of 140 mg dantrolene in total under suspicion of having neuroleptic malignant syndrome, but her symptoms improved slightly. After being transferred to our hospital, she exhibited immobility, mutism, rigidity, and catalepsy, and she was suspected of having lethal catatonia. Infusion of diazepam 10 mg resulted in dramatical improvement of her symptoms. Differential diagnosis between neuroleptic malignant syndrome and catatonia is difficult; however, a first line therapy is differential diagnosis. Thus, physician should consider catatonia when treating neuroleptic malignant like syndrome.
