Epidural blood patch (EBP) was performed for the treatment of severe postlumbar puncture cephalalgia in 118 young patients. Following the first EBP, 105 patients had relief of headache. Eleven of the 13 in whom it failed had a second EBP, with adequate relief in 10, giving an overall success of 97.5 percent. Lumbar epidural, caudal, and spinal procedures were successful in 3 patients 105 to 380 days after EBP. Soon after EBP, one patient developed facial paralysis and one complained of episodes of vertigo, dizziness, tinnitus, and ataxia without headaches. Residual complications included backache and/or back stiffness in 22 patients and paresthesia in two. Two-year follow-up revealed 95 percent patient acceptance of the procedure. EBP was found to be a safe, effective method for treating severe postlumbar puncture cephalalgia, provided a proper diagnosis is made and there is no contraindication.

Five cases of round window membrane rupture were described and under went surgery with gelfoam and/or adipose tissue repair. Short term post-operative follow-ups for a period of three to five months showed complete recovery of vestibular function yet only slight to moderate recovery of the cochlear. The clinical complex of sudden S.N. hearing loss, tinnitus with or without vertigo and ataxia is not uncommon and often presents a diagnostic problem. The patient is anxious to prevent further attacks and yearning for a cure from this relatively disabling condition. Among other causes, viral labyrinthitis and labyrinthine vascular occlusion have been blamed. R.W. membrane rupture, whatever is its underylying factor, as a cause of this clinical complex is well established. A well-planned management i.e. bed rest and/or properly timed exploratory tympanotomy with round window membrane tissue grafting may lead to a partial or total cure.

During the last 10 years, the rupture of the inner ear windows, as an entity, has been introduced in the differential diagnosis of the acute vestibulocochlear syndrome. Head trauma, Valsalva-like maneuvers and barotrauma due to diving accidents are now described as etiologic factors in the pathogenesis of labyrinthine fistula. Four cases were explored and repaired in the last four years in our department. Ataxia was the prominent symptom in three, while positional nystagmus and vertigo were consistent findings in all four cases. The definitive evidence of the fistula can be proved only by exploratory tympanotomy. In this report, the importance of the consideration of this entity in the differential diagnosis of vestibulocochlear syndrome in victims of traffic and diving accidents is emphasized.

Two members of a family suffer from recurrent attacks of either vertigo or cerebellar incoordination. The occurrence of these two distinct types of attack in the same patient may reconcile the disparate features of previously reported cases of familial periodic ataxia. The finding of downbeating nystagmus suggests a medullary disturbance. As in a previously reported family, the attacks were relieved by acetazolamide.

Clinical observations on ciguatera were collected between 1964 and 1977 on 3,009 patients from several South Pacific island groups. Patients generally presented with neurologic symptoms such as parasthesia, vertigo, and ataxia, in addition to gastrointestinal symptoms such as diarrhea, abdominal pain, nausea, and vomiting. Patients with this illness usually became symptomatic less than 24 hours after ingestion of the fish and most patients (76.8%) developed symptoms in less than 12 hours. Significant differences in certain symptoms were noted between Melanesian and Polynesian ethnic groups, suggesting a susceptibility difference, or a difference in the nature of the toxin found in different areas of the Pacific. Being poisoned multiple times appeared to result in a clinically more severe illness than disease observed in patients experiencing ciguatera for the first time.

Clinical and histological findings are presented as occurring in a male aged 24 years suffering from relapsing polychondritis (r. p.) of 7 years duration. The presenting symptoms were fever, ataxia, vertigo and vomiting. During the later relapses there also occurred episcleritis, paresis of the glottic muscle and hypertrophic bronchitis. At the age of 22 the patient had had a tracheostomy because of acute respiratory insufficiency. The patient has a typical saddle nose and drooping auricles. Tissues obtained from the auricles showed destructive alterations of the cartilage with fragmentation and homobenization of the elestic fibres. The perichondrium showed fibrosis and a massive round-celled inflammatory infiltration.

Ataxia is rarely attributed to lesions of the peripheral vestibular system. In 1973, the first case of ataxia and hearing loss secondary to a labyrinthine fistula was reported. Until now, this syndrome has not been reported in patients under the age of 10 years. A case is presented of a 5-year-old boy with symptoms of ataxia and hearing loss as well as vertigo and tinnitus after head trauma. Three physical findings appear to be most characteristic of patients with perilymphatic fistulas: a positive fistula response, positive positional testing with the involved ear down, and evidence of vestibular ataxia when testing station and gait. The absolute diagnosis of perilymphatic fistula can only be established by exploration of the middle ear space. If a fistula is found, it may be sealed with soft tissue and, if this fails, actual stapedectomy may be required.

It is suggested that damage by mild trauma, viruses or bone disease to the otic capsule or to the membranes between the cochlea and the middle ear is common, and involved in many syndromes of obscure etiology. The clinical perilymph fistula (PF) syndrome can consist of any combination of the following: tinnitus, deafness, phonophobia, vertigo, ataxia, otalgia, facial palsy, headache, diplopia, blackouts, psychological distress. The following testable hypotheses are proposed: otitis media is due to perilymph in the middle ear, with secondary changes resulting from infection or inflammation: otosclerosis results from a slow leak in the presence of enzymes promoting bone growth: Meniere's syndrome follows reduced perilymph support for the endolymphatic system: Bell's palsy results from a perilymph provoked oedema in the bony facial nerve canal: PFs may be responsible for progressive rubella deafness, and for some cases of migraine, epilepsy, anxiety neurosis and hysteria: psychiatric sequelae of the PF syndrome predominate in the post-concussional syndrome and infantile autism: organisms can pass from the throat into the spinal fluid, causing meningitis or encephalitis. The tinnitus and vertigo are caused by random labyrinthine fluid movements, the headache and diplopia by reduced spinal fluid pressure.

Minocycline hydrochloride is a tetracycline derivative that has been advocated as the drug of choice in the treatment of meningococcal carriers. Recently, we studied a group of 30 patients who experienced a large number of side-effects after receiving minocycline for treatment of meningococcal meningitis. Twenty-seven of 30 (90%) suffered from dizziness, vertigo, ataxia, weakness, nausea, and vomiting. These symptoms appeared within the first 72 hours of taking minocycline, and disappeared within 48 hours of stopping the medication.

To test the validity of the hypothesis that irritation of the cervical sympathetic nerves is a cause of hypertonicity of the cervical soft supporting tissues, especially the deep nuchal muscles, and that this hypertonicity is a cause of traumatic vertigo of cervical origin, we examined 44 vertigo cases with whiplash injury by testing equilibrium function and EMG discharges from the neck before and after administration of drugs affecting the sympathetic receptors. The results obtained were as follows: 1. Administration of iso-proterenol (beta-receptor stimulant) caused a significant increase in the EMG's from the injured neck muscles, in parallel with increased impairment of the righting reflex. The blindfolded vertical writing test showed the appearance or intensification of ataxia or deviation in writing when this drug was given. In contrast, administration of propranolol (beta-receptor depressor) had the opposite effects on the EMG's, the righting reflex and blindfolded vertical writing. Furthermore, the resulting changes in the EMG's and equilibrium functions were parallel with alterations in subjects' complaints, i.e., increase or decrease in neck pain and vertigo. 2. Administration of drugs affecting the alpha receptors, such as noradrenaline (alpha-receptor stimulant) and phentolamine (alpha-receptor depressor) had no appreciable effect on the EMG's, equilibrium function or the subjects' complaints. These results show that in vertigo due to whiplash injury hypertonicity of the cervical erector muscles can be induced sympathetically, and that this hypertonicity is based on over-excitement of beta receptors in the injured neck muscles, which results in vertigo of cervical origin.
