The duration of the stimulating effect of transplacental transferred thyrotropin-receptor-antibodies (TRAb) is discussed by the example of a 23 years old woman suffering from Graves' disease with a severe hyperthyroidism. She became pregnant six weeks after the diagnosis was obtained and then discontinued her antithyroid medication on her own responsibility. On a check-up in the 20th week of pregnancy, a hyperthyroidism was once more found, leading to a therapy with propylthiouracil, which however, was again interrupted by the patient a few weeks later. In the 32nd week, she gave birth to a male child that already presented with distinct signs of thyrotoxicosis and developed a continuous deterioration of the condition, including a tachycardia with up to 190 beats per minute, fever, tremor and a respiratory disorder. Assay of the newborn serum revealed a severe hyperthyroidism. The TRAb level was 180 U/l (normal range < 15). A therapy with propranolol and prednisolone was initiated, leading to a significant improvement of the general condition. Nevertheless, after 12 days, there was still no notable decrease of the hormone levels. Therefore an antithyroid medication was started, which caused normal thyroid hormone levels within 9 days. However, after the therapy was stopped, a hyperthyroidism was again observed within one week, requiring another, low-dose antithyroid medication, which was administered for 26 days. After this period, the TRAb level was down to 25 U/l and no more hyperthyroidism was found. The biological half-life of the TRAb was 20 days in our case.

A 36-year-old Japanese woman was admitted to our hospital, because of facial palsy, ophthalmoplegia, cerebellar ataxia, and rhythmic myoclonus of the neck. About a few weeks before admission, she developed symptoms of common cold and general fatigue. Her laboratory data were unremarkable, and her CSF was normal. Serum levels of antibodies to gangliosides were within normal limits. Her MRIs of the brain and neck were normal. Both somatosensory evoked cortical potential study and auditory evoked brainstem response study were normal. She was diagnosed as postinfectious brainstem encephalitis, and the administration of corticosteroid was started. After the treatment, her symptoms improved. To our knowledge, it is rare to see myoclonus to the neck without palatal tremor in patients with brainstem encephalitis.

We report a 73-year-old Japanese woman with familial Parkinson's disease. The patient was well until her 67 years of the age, when she noted rest tremor in her right hand. Soon after her gait became short stepped. She visited our clinic on October 6, 1992 when she was 68 years old. She was alert and well oriented without dementia. She showed masked face, small voice, small stepped gait, retropulsion, resting tremor in her right hand, rigidity in the neck, and bradykinesia. She was treated with 400 mg/day of levodopa-carbidopa, which improved her symptoms, however, she developed wearing off phenomenon 3 years after the initiation of levodopa treatment. On August 26, 1998, she developed abdominal pain, diarrhea, and vomiting. She was admitted to another hospital, where abdominal plain x-ray revealed an evidence of intestinal obstruction (ileus). She was treated with nasogastric suction and intravenous fluid. Her condition did not improve and she was transferred to our hospital on August 29, 1998. Her family history revealed no consanguineous marriage. She had two elder brothers and three elder sisters. One of her brothers had been diagnosed as Parkinson's disease. Her husband also suffered from Parkinson's disease, however, her parents apparently did not have Parkinson's disease. On admission, she appeared to be drowsy. Her blood pressure was 102/70 mmHg, body temperature 36.2 degrees C. The lungs were clear and no cardiac murmur was present. Abdomen was flat and bowel sound was audible. No abnormal mass was palpable. Neurologic examination revealed mild consciousness disturbance, masked face, and small voice. No motor paralysis was noted. Muscle tone was hypotonic. No abnormal involuntary movement was noted. Abnormal laboratory findings on admission were as follows; WBC 11,300/microliter, amylase 1,373 IU/l, CK 446 IU/l, BUN 50 mg/dl, creatinine 1.17 mg/dl, CRP 22.7 mg/ dl, Na 134 mEq/l, K 3.1 mEq/l, and Cl 81 mEq/l. A chest x-ray film revealed pneumonic shadows in both lower lung fields. She was treated by nasointestinal suction, intravenous fluids, and chemotherapy for her infection. Her BP started to drop on September 2 and she developed cardiac arrest on the same day. She was discussed in a neurological CPC. The chief discussant arrived at the conclusion that the patient had a form of autosomal dominant familial Parkinson's disease. As parents did not have Parkinson's disease, some of the participants raised the possibility of autosomal recessive inheritance. But the age of onset was too late for autosomal recessive inheritance. Majority thought that the mode of inheritance was autosomal dominant with low penetrance. alpha-Synuclein mutation causes an autosomal dominant familial Parkinson's disease, but this type is very rare in non-Greek populations and the penetrance is high. Chromosome 2-linked autosomal dominant familial Parkinson's disease shows low penetrance. There are many other autosomal dominant forms of familial Parkinson's disease linked to yet unknown chromosome loci. Majority thought that this patient also had a form of Lewy-body positive autosomal dominant familial Parkinson's disease of unknown chromosome locus. Post mortem examination revealed ischemic intestinal lesion with strangulation. This was thought to be the cause of her death. In the central nervous system, the brain appeared to be normal by inspection. In the coronal sections, the substantia nigra and the locus coeruleus showed marked depigmentation. Histologic examination revealed marked neuronal loss and Lewy body formation in the remaining neurons. Pathologic examination was consistent with Parkinson's disease. Mutational analysis for the parkin gene was negative.

A 70-year-old woman began to experience gait disturbance in 1995, followed by the appearance of action tremor of the left hand in 1996. This tremor was subsequently noted in the right hand. Her doctor initially diagnosed Parkinson's disease and administered amantadine and levodopa. The gait disturbance and tremor improved. However, she stopped taking the medication and her symptoms worsened in April, 1998. She was admitted to our hospital, and showed rigidity and action tremor predominantly on the left side, frozen gait, postural reflex disturbance and orthostatic hypotension. Following levodopa administration, her UPDRS score improved from 61.3 +/- 1.2 (mean +/- SD) to 41.7 +/- 5.4. However, she experienced a greater decrease in systolic blood pressure following administration upon standing, from 12.5 +/- 5.8 mmHg to 17.8 +/- 9.2 mmHg. Thus, although levodopa administration led to an improvement in rigidity, tremor and akinesia, her orthostatic hypotension worsened. Based on the present results clinicians should be aware of the potential of worsened orthostatic hypotension when prescribing levodopa to treat Parkinson's disease.

We report a 50-year-old right-handed woman who, at age 20, was diagnosed to have homocystinuria presumably due to cystathionine beta-synthase deficiency. At age 40 years, involuntary movements developed insidiously, affecting her face, neck and upper limbs. During the next 10 years, involuntary movements progressed and she could no longer walk. Examination disclosed bilateral lens dislocation and marfanoid skeletal deformity. Muscle strength was mildly decreased in the right arm and bilateral legs. There was hyperreflexia in the right upper and bilateral lower extremities without Babinski sign. Muscle tone was mildly increased in the neck and bilateral upper extremities. She had persistent generalized choreic movements, dystonia affecting the face and neck, and resting and postural tremor in the upper limbs and tongue. A cranial CT scan showed an old low density lesion in the left frontal area. Involuntary movements in homocystinuria is rare and, to our knowledge, only 9 cases have been reported. This case was unique in that involuntary movements developed in the adulthood.

To elucidate the nigrostriatal involvement in rubral tremor, we studied single photon emission computed tomography (SPECT) imaging with [2-[[2-[[[3-(4-chlorophenyl)-8-methyl-8-azabicyclo[3.2.1]oct-2- yl]methyl](2-mercaptoethyl)amino]ethyl]amino]ethanethiolato(3-)- N2,N2',S2,S2']oxo-[1R-(exo-exo)]-[99mTc]technetium ([99mTc]TRODAT-1) in a 70-year-old woman with a midbrain hemangioma. She had developed a slow tremor in her right arm and leg after an episode of hemorrhage at the age of 28. The tremor was 3 to 5 Hz in frequency at rest, which was enhanced by outstretching the limb and action. There was no rigidity or bradykinesia. Neurological examination also revealed mild palsy of the left oculomotor nerve. The magnetic resonance imaging (MRI) of the brain showed a small hemangioma in the left midbrain localized mainly in the substantia nigra. The [99mTc]TRODAT-1 SPECT imaging revealed significantly reduced [99mTc]TRODAT-1 uptake in the left caudate and putamen, but it was only mildly reduced in the right striatum. This reduction in uptake was even more severe than that of patients with Parkinson's disease, and indicated that the dopamine function was markedly impaired in the left nigrostriatal system. The tremor had not progressed over the years, and she responded moderately to treatment with levodopa. We concluded that the rubral tremor in the right extremities was probably caused by a dopamine deficiency in the left nigrostriatal system. This suggests that a dopamine deficiency secondary to the midbrain hemangioma might have contributed to the development of the rubral tremor in this patient.

We report the clinical laboratory, electroencephalography (EEG), magnetic resonance imaging (MRI) and single photon emission computerized tomography (SPECT) findings in a 15 year-old euthyroid girl with autoimmune thyroiditis and encephalopathy. She had stupor, coma and generalized tonic clonic seizure preceded by tremor and myoclonus with a previous misdiagnosis of epilepsy and encephalitis. Response to steroid after the 3rd relapse was excellent. Another four children in the literature are also discussed.

The authors present a very rare case of Holmes tremor (previously known as rubral or midbrain tremor). In all described till now cases the tremor was due to a known and revealed in laboratory or neuroimaging cause. We present an unusual case of a 42-year old woman with unilateral tremor of right extremities (mostly proximal part of upper extremity) which started abruptly 3 years ago. She had no suffer any serious disease before the onset of symptoms and her family history was also negative. The tremor was present at rest but accelerated during specific postures and active movements. The laboratory tests including: copper and ceruloplasmin concentrations, blood analysis for acanthocytes, evoked potentials, EEG, CT, MRI, MRA and SPECT did not reveal any significant changes. Treatment attempts with neuroleptics, clonazepam, L-dopa, valproic acid, biperiden were almost completely ineffective except local injections of botulinum toxin (Botox, Allergan, 150 U) into the muscles of right arm girdle which moderately alleviated tremor. We did not find any underlying pathology as a cause of tremor, clinically the same as symptomatic cases described in literature. We suggest the possibility of idiopathic origin of tremor in our case, although a very small size of lesion (f.i. ischaemic) could be undetectable in the described tests.

Relapsing polychondritis is a chronic inflammatory disease associated with an autoimmune disorder in cartilaginous tissue, eyes, labyrinth, blood vessels, and central nervous system. We describe a 75-year-old woman who presented with a 20-year history of dyspnea, inspiratory stridor, and polyarthritis. She developed dysmorphism of both ears and a saddle nose approximately 10 years earlier. Subsequently, she suffered from hearing loss and a tremor. A T2-weighted magnetic resonance imaging scan of the brain revealed multiple, spotted signal intensities. Immunohistochemical analysis of a serum sample showed antibodies to cartilaginous tissue, which were further identified on immunoblotting as antibodies to type II collagen. The extremely prolonged course of disease (>20 years) until a correct diagnosis was made is remarkable. Also, cerebral involvement, which was most likely caused by cerebral angiitis, and which, to our knowledge, has never previously been reported in this form, was detected.

We report a 57-year-old woman with progressive gait disturbance and mental deterioration. She was well until March 1995, when she was 54 years of the age. At that time she noted a gradual onset of tremor and difficulty using her hand. Similar symptoms appeared in her right hands, and she visited another hospital, where 300 mg of levodopa and 7.5 mg of bromocriptine were prescribed. These medication did not help her symptoms. In the summer of 1996, she became to fall down easily. In September of the same year, she started to repeat the same words many times. She was unable to stop it. She was hospitalized to our service on January 25, 1997. On admission, she was alert but demented moderately; her Hasegawa dementia scale was 15/30. She showed palilallia, logoclonia, and echolalia. She showed constructional apraxia and questionable left-right disorientation. She had marked vertical gaze palsy with preserved oculocephalic response. She had masked face and small voice. Her gait was wide based with small steps. No muscle atrophy or weakness was noted. She showed only mild rigidity in the neck, but no rigidity was noted in the limb. No tremor was noted. She was bradykinetic. Deep tendon reflexes were symmetric and within normal limits. Laboratory findings on admission was unremarkable. MRI showed atrophy of the brain stem as well as cerebral cortical areas, particularly in the fronto-temporal region. Her hospital course was complicated with paralytic ileus and septicemia. She developed hypotension and pronounced dead on July 28, 1998. She was discussed in the neurological CPC. The chief discussant arrived at a conclusion that the patient had progressive supranuclear palsy and died of septic shock. All the participants wondered between PSP and CBD, but majority agreed with this diagnosis of the chief discussant. Only one thought that she might have had corticobasal degeneration rather than PSP, because of dementia, cortical atrophy in MRI, and lack of limb rigidity. Postmortem examination revealed cortical and brain stem atrophy. In the premotor cortex, marked astrocytosis and ballooned neurons were seen. Furthermore, astrocytic plaques were seen; this is considered to be pathognomonic for CBD. The substantia nigra showed marked neuronal loss and gliosis, but no neurofibrillary tangles or Lewy bodies were seen. Gliosis was also seen in the globus pallidus and in the medial thalamus. The pathologic diagnosis was corticobasal degeneration. This patient was very interesting case, in that the clinical manifestations appeared to be consistent with PSP, yet pathologic diagnosis was CBD. Lack of limb rigidity may be atypical for advanced PSP. In addition, palilalia appears to be more associated with CBD.
