Chloroquine is considered essentially nontoxic when used for the chemosuppression of malaria, but gastrointestinal upsets, headache, blurring of vision, pruritus, and uritcaria may occur during chloroquine therapy. Recently, Bhargava et al. and Eronini and Eronini have reported the extrapyramidal syndrome (EPS) following chloroquine therapy in adults. The clinical manifestations included upward rolling of the eyeballs, retraction of neck and back, trismus with marked difficulty in speech, and coarse tremors. Observations of 4 instances of EPS in children following chloroquine therapy for malaria are reported. A 2-1/2 year old girl was admitted to the All India Institute of Medical Sciences Hospital with a 4 day history of intermittent high grade pyrexia with chills and rigors. Following treatment with oral chloroquine in the recommended therapeutic dosage, the fever responded, but the child became drowsy and developed paroxysms of involuntary movements of the tongue, torticollis, torsion dystonia of the limbs, and parosysms of tonic muscular spasms. She completely recovered spontaneously within 48 hours. The 2nd case was that of a 12-year old female brought to the hospital with a 15-day history of intermittent high grade fever with chills and rigors. The patient was started on chloroquine sulfate in the recommended therapeutic dose. After an interval of 4 days she developed coarse tremors of the hands, upward rolling of the eyeballs, episodic deviation of the angle of the mouth towards the left, and trismus. These symptoms disappeared spontaneously within 8 hours. A 6-year old girl, the 3rd case, developed episodes of opisthotonous, upward rolling of the eyeballs, protrusions of the tongue, intermittent writhing movements of the upper limbs, and drowsiness following the ingestion of 6 tablets of chloroquine sulfate for suspected diagnosis of malaria. She spontaneously recovered from EPS over a period of about 48 hours. The 4th case, a 7-year old boy, gave a history of high grade fever with chills and rigors of 1 day's duration. He developed drowsiness, tonic spasms of the neck, upward rolling of the eyeballs, and writhing contortions of all limbs about 2 hours following intravenous administration of 100 mg of chloroquine. 8 hours later an additional 100 mg chloroquine was given intravenously for the mistaken diagnosis of cerebral malaria. On examination the child was drowsy, had generalized stiffness, torticollis, and trismus. He recovered gradually over a 48-hour period without any specific therapy. The exact mechanism of production of EPS remains uncertain.

Since Snyder reported first twelve cases of benign paroxysmal torticollis in infancy (BPT) in 1969, about 30 cases have been reported mainly in the North America and Europe, but not in Japan. The authors experienced such a case of one-year-old boy. The attack occurred at the age of 2 months for the first time and continued to repeat every 2 weeks periodically. The head tiltings were always noticed when he woke up in the morning and lasted for about 5 to 6 days, but they disappeared during sleep. He tilted his head to the lateral side more often to the left than to the right. There were associated symptoms and signs including irritability, vomiting, gait disturbance, and abnormal truncal posture during the attacks. He did not demonstrate any neurological abnormalities between the attacks. The study of cerebrospinal fluid, caloric test, computed tomography, electroencephalography and brainstem auditory evoked responses were also normal. The frequency of the attacks gradually decreased after the age of 2 years and disappeared at the age of 3 years, and he has not complained of severe headache or vertigo up to 6 years of age. This case is reported to emphasize that BPT has to be included in the differential diagnosis of acquired torticollis. And it is required to accumulate such cases to elucidate its etiological factors.

A 6-year-old girl had a 7-month history of headaches and painful torticollis. A CT scan of the mastoids showed extensive bone destruction of the base of the skull and C-1. Biopsies of the retropharyngeal area and of the anterior aspect of C-1 were performed: histopathologic findings were suggestive of mycotic infection and cultures were positive for Candida albicans. The child was treated successfully with amphotericin B. The immunologic evaluation demonstrated the absence of myeloperoxidase in the neutrophils.

Lithium has been put to clinical trials in no less than fifteen neurological disorders. They are Huntington's chorea, tardive dyskinesia, spasmodic torticollis, Tourette's syndrome, L-dopa induced hyperkinesia and the "on-off" phenomenon in parkinsonism, organic brain disorders secondary to brain-injury, drug induced delusional disorders, migraine and cluster headache, periodic hypersomnolence, epilepsy, meniere's disease and periodic hypokalemic paralysis. This paper gives a brief summary of the clinical trials with lithium salts reported in the literature. There are encouraging results on the use of lithium in cluster headaches, cyclic form of migraine and hypomanic mood disorders due to organic brain disorders. The trials with lithium and amitriptyline in tardive dyskinesia needs independent confirmation. The effect of lithium on seizure disorders needs to be addressed too.

The two main problems in defining and classifying the syndrome of benign paroxysmal vertigo (BPV) in childhood are the vestibular function pattern and the relationship between BPV and migraine. 13 children suffering from this syndrome were submitted to complete otoneurological examination, including caloric and rotational labyrinthine stimulation with ENG recording, and to headache provocation tests with nitroglycerin, histamine and fenfluramine. Vestibular responses were normal in all except 2 cases which presented signs of central vestibular impairment at the level of the vestibulocerebellar pathways. Headache provocation tests were positive in 9 out of 10 children, and in 4 cases they induced a typical vertiginous attack instead of headache. In addition, several children had a positive family history for migraine, headache was frequently associated with the crisis and other signs of a 'periodic syndrome' (motion sickness, cyclic vomiting, abdominal pain) were present, unrelated to vertiginous attacks. During the follow-up period, some children responded positively to migraine treatment. BPV, like paroxysmal torticollis in infancy and the signs of the periodic syndrome, can be considered a migraine equivalent or a migraine precursor and could be due to the same vascular and/or biochemical mechanisms responsible for the migraine. In children, for anatomical or developmental reasons, these mechanisms could selectively affect parts of the brain stem, including the vestibular nuclei and vestibulocerebellar pathways.

Cervical spondylolisthesis is a rate vertebral anomaly that has not been associated with other major congenital abnormalities. In a 16-year-old girl, lower cervical spondylolisthesis was associated with a multiple nevoid basal cell carcinoma syndrome. The salient features of cervical spondylolisthesis include occipital headache, nuchal rigidity, torticollis, painful range of limited motion, hypesthesia, and depressed deep tendon reflexes. The treatment in the patient was anterior vertebral body fusion. Awareness of this associated problem and prompt treatment are essential for prevention of neurologic loss.

Headache, nausea, ataxia and diplopia are leading symptoms of brain tumors in children. We report of 3 children with unusual symptoms and findings. Patient 1 complained of occasional headaches. Clinical examination showed neurological deficits and uveitis. Lumbar puncture revealed a pleocytosis and the oligoclonal banding study was positive. Cranial MRI demonstrated an enlarged pons. Under treatment with cortisone a clinical improvement was seen, but no change of the abnormalities in MRI. Several weeks later a biopsy was performed, which verified an astrozytoma. The second child developed a torticollis, following an accident, and later a refractory constipation was noted. A clinical evaluation was within normal limits. Several weeks later the patient complained of bladder disturbances. Patient 3 had a lateralized tic disorder without any neurologic deficits. CT showed an infratentorial tumor above the 4th ventricle. The tic disorder vanished only after the tumor was completely resected in the second operation. The reported cases demonstrate the fact that in an individual patient a brain tumor can cause unusual symptoms and findings which do not make the diagnosis obvious.

Torticollis in childhood may be a sign of many disorders. Five cases, with torticollis as the initial sign of a posterior fossa tumor, are presented. The diagnosis and treatment of the tumor was considerably delayed in all patients because posterior fossa tumor was not considered in the initial differential diagnosis. In two patients, operative procedures on the sternocleidomastoid muscle were performed before discovering the underlying causative tumors. Four of the five patients also had other associated symptoms such as headache, nausea, and vomiting. It is stressed that in acquired torticollis, posterior fossa tumor be considered in the differential diagnosis.

Torticollis results from various pathological mechanisms, and its elucidation depends on identifying diseases of musculoskeletal, neural and ocular tissues. This study characterized the underlying diseases of children hospitalized with torticollis, excluding congenital torticollis. Records of 36 children with torticollis seen during 4 years were reviewed and categorized according to presumed etiology. Most could be classified into 2 categories: in 39% it was due to trauma and in 36% to upper respiratory tract infection. Most girls were in the first group and most boys in the second group. There were 3 cases of ocular torticollis due to superior-oblique muscle palsy, 1 with a post-burn eschar, 2 with neurological disorders (intramedullary cervical astrocytoma and leukodystrophy with macrencephaly), and in 3 no associated cause was found. There was a clear seasonal trend with 58% of cases presenting from November through February, 33% from April through July, and the rest, of neurological or ocular origin, during the rest of the year. In cases of post-traumatic torticollis 21% had neurological symptoms such as weakness of the limbs, headaches or incontinence. Only a few had prior upper respiratory tract infection. All children whose torticollis was assigned to infection had had fever. Only 8% had had neurological complaints or vomiting, half of whom presented with fever exceeding 37.5 degrees C. 46% had restriction of movement and 38% had tenderness. In over 60% of those in this group there were signs of an upper respiratory tract infection, such as lymphadenopathy or a white blood cell count exceeding 15,000/microliter, 3 patients with recurrent torticollis were diagnosed as having severe neurological diseases. Mean hospitalization time was 4 days (range 1-28). Hospitalization periods were similar for all kinds of patients and treatment by traction or fixation did not affect this period.

Measurable sources of muscle tension include viscoelastic tone, physiological contracture (neither of which involve motor unit action potentials), voluntary contraction, and muscle spasm (which we define as involuntary muscle contraction). The latter two depend on motor unit action potentials to generate the tension. Total muscle tension is most accurately measured as stiffness. Thixotropy of muscle is an ubiquitous and functionally important phenomenon that is not commonly recognized. A clinical pain condition associated with increased muscle tension is tension-type headache, which is largely muscular in origin; it is often caused by myofascial trigger points, but not by a pain-spasm-pain cycle, which is a physiologically and clinically untenable concept. Clinical conditions associated with painful muscle spasm include spasmodic torticollis, trismus, unnecessary muscle tension, nocturnal leg cramps, and stiff-man syndrome.
