Thirty-four patients were submitted to the conventional cervical myelography by administration of metrizamide (Amipaque) through three routes (lumbar 23, suboccipital 6, C1-C2 lateral 5). After the injection of metrizamide (4-11 ml, 170-250 mgI/ml), all procedures of the cervical myelography were done as soon as possible within 9 minutes. The adverse reactions of Amipaque were observed in 29 cases (85%) out of 34 cases initially 1 hour after cervical myelography and disappeared completely in an average of 16 hours. The total number of the side effects was 140 incidences such as meningeal irritation (headache 18, nausea 17, vomiting 17), cerebellar signs (dizziness 11, dysarthria 8, tremor 5, bradylalia 2, dysmetria 2, tipsy feeling 2, dysdiadochokinesis 1), autonomic signs (flushing 7, pale face 4, fever 4, sweating 2, hiccup 2, fatigability 2, micturition disturbance 1), sensory signs (exacerbation of numbness 6, perioral numbness 3, back pain 1, chest pain 1), motor signs (focal muscle spasm 5, exacerbation of paresis 4, areflexia 1), psychiatric signs (dysphasia 3, disturbance of consciousness 2, euphoria 1, persecutory delusion 1) and muddiness 7. We observed that waxing and waning of side effects correlated tightly with transient cortical penetration of dye in CT and cortical dysfunction mainly slowing of the background activity and slow wave burst in EEG. According to high frequency of side effects in our study, we suggest that a greater incidence of side effects may result when high concentration of Amipaque comes in contact with the cerebral cortex by using an inadequate fluoroscopic table which has only fixed one plane image and rough positioning control. Slow absorption into blood stream may affect appearance and maintenance of side effects. In order to decrease side effects after Amipaque cervical myelography, we propose that we should introduce a mobile rotating chair coupled with high power image and chose C1-C2 lateral route using 1500-1700mgI of Amipaque.

Harlequin syndrome (HS) is a rare disorder of the sympathetic nervous system which presents with unilateral decreased sweating and flushing of the face, neck, and chest in response to heat, exercise, or emotional factors. The contralateral side displays a compensatory overreaction to provide normal heat regulation of the face as a whole. In the literature, most of the cases are primary in nature and no underlying cause could be identified. Harlequin sign is used to denote these symptoms in patients who also exhibit associated oculosympathetic paresis, such as Horner syndrome, Adie syndrome, and Ross syndrome.We report a rare case of a 13-year-old boy who presented with complaints of flushing and sweating of the left side of the face after exertion, while the right side remained dry and maintained its normal color. No structural abnormality was identified on detailed work up. Thus, diagnosis of classic idiopathic HS was made. Despite the rarity of this syndrome, dermatologists should be acquainted with this distinctive entity and should refer the patient for complete ophthalmological and neurological examination.
