We present 3 new cases of cervical epidural abscess (CEA), a rare condition, along with a review of 12 other case reports. The average patient age was 45 years; just over half were male. The abscesses usually involved the mid to lower cervical region and extended an average of three to four segments. Neck stiffness was present in all patients; root pain and paresthesias were present less often. Weakness of one to four extremities developed in all but one patient. Sensory levels were frequently present, sometimes below the site of the lesion. All but two patients were febrile. All but two had elevated CSF protein, and all but two had a pleocytosis; myelography always revealed a complete or partial block. Staphylococcus aureus was the causative organism in 8 of 11 patients. CEA should be considered in a patient with neck stiffness, paresthesias, and/or radicular pain so that CT or myelography followed by surgical decompression and/or antimicrobial drugs can be initiated before prolonged weakness develops. One of our patients developed a syrinx causing a new neurologic deficit 3 years after treatment. Delayed syringomyelia, a rare complication of extramedullary lesions, lends support to vascular occlusion as the major mechanism of damage in epidural abscess.

Weakness accompanying hyperthyroidism may be due to a variety of causes. A case is presented of a patient who, during management of thyrotoxicosis, became quadriparetic due to a unique combination of axonal neuropathy, myopathy, and pyramidal tract dysfunction. Electrodiagnostic, muscle biopsy, and nerve biopsy results are presented.

Twenty-one cases of hamulus fracture are presented. Diagnosis depends on clinical acuity. The most common symptom is pain in the palm that is aggravated by grasp. Weakness of grasp and dorsal wrist pain are also common. Ulnar nerve paresthesia or weakness and mild carpal tunnel syndrome are frequently present. Tenderness directly over the hamulus is always present, and grip strength typically is diminished. Tenosynovitis, tendon fraying, or tendon rupture may be demonstrated in 25% of the cases and is not related to the use of steroids. Lateral trispiral tomography is clearly superior to the other diagnostic methods. Excision produced generally excellent results, particularly in patients with an athletic injury or with no associated additional injury. A nonathletic injury or the presence of associated trauma adversely affected results. Immediate immobilization of acute fractures may result in fracture healing and obviate operative intervention. Open reduction and internal fixation is feasible but offers little advantage over excision.

Ninety-two patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) have been studied in order to define better the clinical features, course and prognosis of the condition and to identify possible aetiological factors. Sural nerve biopsy was performed on 87 subjects. Electrophysiological studies were undertaken on all patients and demonstrated marked slowing of motor conduction and impairment of sensory conduction. The onset was usually gradual but there was a rapid rate of onset in 15 (16%) patients. Males were more commonly affected than females. Weakness and paraesthesiae were the most common symptoms but pain was frequently a feature. Age of onset ranged from 2 to 72 years. Sixty patients (65%) had a relapsing course and 32 patients (35%) a progressive or monophasic course; there was a significantly earlier age of onset in patients with relapsing disease. Thirty-two patients (35%) gave a history of preceding infection or some other possible antecedent precipitating event and there was a significantly higher titre for cytomegalovirus antibodies in the serum of patients with CIDP than in controls. The patients were followed up for an average time of approximately ten years. Most patients (73%) had made a good recovery and were independent, but 7 patients had either died or were completely immobilized as a result of their disease. The value of treatment with corticosteroid therapy, immunosuppressive agents and plasma exchange is discussed.

Five patients with pseudoexfoliation syndrome (PES) and glaucoma developed extensive zonular dialyses during extracapsular cataract extractions. Weakness of the lens zonules or their attachments to the ciliary processes, which has been described in association with PES, may explain this complication. We believe that patients with PES are at particular risk for developing large zonular dialyses during extracapsular surgery. Preoperative phakodonesis, anterior chamber depth asymmetry, and excessive lens movement during the anterior capsulotomy should alert the surgeon to this problem.

Eight cases, 5 males and 3 females, of Chiari type 1 malformation aged from 9 to 51 years (mean 33.3 years) were analysed. The average age of the onset of symptoms was 29.6 years, between 7 and 44 years, and that from the onset of symptoms to the presentation to the hospital was 3.3 years ranged from 1 month to 16 years. Pain (87%) in the head or in the cervical region was the most common symptoms, the former was 5 cases and the latter was 2. The next common symptoms were unsteadiness and gait disturbance (50%). Weakness of one or more limbs was the complaints of 3 (38%) of the patients, and sensory impairment was 38%. Other symptoms included stiffness of the neck and shoulder, limitation of the neck movement, abnormal head posture, rectourinary incontinence and so on. In physical examination, foramen magnum compression signs (63%) and cerebellar signs (63% were most common and lower cranial nerve palsy (38%) and intracranial hypertension (25%) were included. Abnormalities of the skull and cervical spine were common on X-ray films. The were cervical fusion or occipitalization and basilar impression. On the angiograms, descended PICA was visualized in all cases. CT metrizamide myelography was performed in 2 cases and MRI was done in 1 case. They could clearly demonstrate the descended tonsils and were found to be the most reliable radiographic examination in the disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Weakness of the muscles of the pelvic floor and external anal sphincter may in theory be caused by a traction injury to the pelvic nerves incurred as a result of the excessive perineal descent that accompanies straining in the descending perineum syndrome (DPS). To investigate the role of this weakness in the aetiology of idiopathic faecal incontinence (IFI), measurements of perineal position, puborectalis mean fibre density (MFD), anal canal pressures, rectal sensation, capacity, and compliance were made in continent (DPS alone, n = 20) and incontinent (DPS + I, n = 19) patients with DPS, and a group of age and sex matched control subjects (n = 20). Perineal descent on straining was greater in DPS alone than in DPS + I. Puborectalis MFD was raised by similar degree in both DPS groups compared with the control subjects, and external anal sphincter function, assessed as voluntary squeeze pressure, was impaired by similar degree in DPS + I and DPS alone compared with the control subjects. Maximal basal anal canal pressure and rectal compliance were significantly reduced in DPS + I compared with DPS alone and the control subjects. Thus IFI did not result from progression of neurogenic muscle weakness, but occurred when there was also diminished internal anal sphincter tone and reduced rectal compliance.

The case of a boy developing a "rigid spine syndrome" from 6 years of age is reported. Weakness and amyotrophy of shoulder girdle were noticed. The muscular biopsy showed a pattern of predominance and hypotrophy of type I fibers, as already reported in comparable cases. The pathophysiology of this exceptional syndrome is discussed.

A case of motor neuron disease with clinical and pathological resemblance to amyotrophic lateral sclerosis (ALS) in a woman who was severely bitten on the ankle by a cat is described. Weakness first appeared at the ankles and relentlessly advanced proximally, terminating in death from pulmonary failure in a year. A number of unusual features that are uncharacteristic of ALS were found that included a markedly elevated antinuclear antibody titre in the serum and the presence of prominent oligoclonal bands in the cerebrospinal fluid. The spinal cord showed loss of anterior horn cells and pyramidal degeneration that are characteristic of ALS, but an extraordinary finding was the presence of transmural granulomatous inflammation of numerous small and medium sized vessels, especially veins, in the subarachnoid space around the cord. There were also inflammatory changes in the brainstem and spinal cord consisting of microglial and astrocytic nodules and perivenous cuffing by mononuclear cells. Ill-defined hyaline eosinophilic cytoplasmic inclusions were seen in some remaining anterior horn cells. No viral particles were found by electron microscopy despite an extensive search. Virological studies were inconclusive but there is reason to believe that this patient's illness was caused by an as yet unidentified virus.

Two distinct patterns of somatization were identified in 807 Swedish adopted men, using comprehensive lifetime psychiatric and sick-leave records. "Diversiform" somatizers had a high frequency of brief sickness occasions for a wide diversity of complaints, particularly pain in the head, joints, and abdomen. "Asthenic" somatizers had a lower frequency and diversity of complaints. They recuperate more slowly, however, and were more often disabled by fatigue, weakness, and minor illnesses such as upper respiratory infections. Both types of somatizers had associated psychosocial maladjustment, but they had discrete clinical patterns, with infrequent overlap. Diversiform somatizers had a higher risk of alcohol abuse, psychiatric hospitalization, and substandard income than either asthenic somatizers or non-somatizers. Asthenic somatizers had a higher risk of divorce than either diversiform somatizers or non-somatizers. Men with prominent somatization had an excess of psychiatric treatment for alcoholism or anxiety disorders, but, unlike female somatizers, no excess of criminality. These clinical differences suggest that the psychiatric processes associated with somatization may be qualitatively different in men and women. The method used here is generally applicable in genetic epidemiology to identify natural clinical subtypes within a heterogeneous phenotype.
