When spasticity becomes severe and harmful, in spite of physical and medical therapy, neurosurgery can give functional improvement. This paper deals with the long term results of Selective Peripheral Neurotomies of the Tibial Nerve and Selective
Posterior
Rhizotomies in the Dorsal Root Entry Zone, in 123 patients with spastic disorders localized to the limbs. The micro-techniques and intra-operative electro-stimulation for identification of the nervous structures responsible for the spastic components, can give a substantial reduction of the harmful spasticity, without suppressing the useful muscle tone and impairing the residual motor and sensory functions. The results were effective, with a 1 to 13 year follow-up (5 on average), in 89% of 47 Selective Peripheral Neurotomies of the tibial nerve for spastic foot, in 92% of 53 Selective
Posterior
Rhizotomies for paraplegia and in 87% of 23 Selective
Posterior
Rhizotomies for
hemiplegia
. In the most severe situations ("comfort" indications), correction of the abnormal postures and relief of pain facilitated nursing and physiotherapy. Sometimes there was reappearance of some useful voluntary movements. In the less affected patients ("functional" indications), the suppression of the harmful spastic components made the persistant capacities more effective.

Posterior
cerebral artery infarction usually causes hemianopsia and, occasionally, symptoms referred to infarction in the territory of the middle cerebral artery. We describe a case of cerebral infarction of the posterior cerebral artery territory that mimicked middle cerebral artery occlusion. A patient with infarction of the right surface and deep territories of the posterior cerebral artery presented with left
hemiplegia
and left homonymous hemianopsia. Brain computed tomography and magnetic resonance investigation disclosed a hypodense lesion in the occipital right lobe and the medial and inferior part of the right temporal lobe. Transcranial Doppler studies disclosed an abnormally increased blood flow velocity in the proximal posterior cerebral artery and a sharp reduction in distal flow velocity. This case underscores the utility of noninvasive techniques to diagnose posterior artery stenosis: they were not only more economical than angiography but also spared the patient discomfort and risk.

Today, we have several efficient neurosurgical treatments of spasticity in children with cerebral palsy. A good indication is possible only if a consensus about the goal of the surgery is found between the surgeon, the child and his/her family, and the reeducation team. This goal is not always functional. Clinical examination is not limited to the analytical assessment of spasticity, but must take into account the general and orthopedic state of the child, and his/her functional evolution, cognitive abilities, habits and general environment. The struggle against spasticity is part of a therapeutical programme which extends over several years. It must be considered before muscular contractures. On lower limbs, in the cases of general spasticity, we propose posterior rhizotomy or intrathecal baclofen administration.
Posterior
rhizotomy is proposed when a more aggressive intervention is preferred for some muscular groups or when the child's general environment does not allow for the medical care imposed by intrathecal administration. In the case of localized spasticity, botulinum toxin injection permits delaying until the child reaches the age for selective neurotomy. On upper limbs, in children with quadriplegia the indication is essentially physical and occupational therapy. We cannot count on the positive side effects of rhizotomy or intrathecal administration of baclofen on the upper limbs. In children with
hemiplegia
, with localized or global spasticity of the upper limb, botulinum toxin is proposed as the first form of treatment. Neurotomy or rhizotomy can follow toxin, according to the efficacy of the toxin.

Posterior
circulation stroke, which includes basilar artery occlusion (BAO), accounts for approximately 20% of all ischemic strokes. Much is unclear concerning the early historical descriptions of basilar artery occlusion, and some modern authors cite the historical sources incorrectly and incompletely. The case described by the Scottish physician John Abercrombie in 1828 is probably the first description of this form of stroke. The progressive bulbar signs that Abercrombie described in his case were striking, i.e., dysphagia and speech difficulties. Many authors in the 19th century described a waxing and waning clinical course for several days before profound coma and death. They also noticed signs and symptoms such as
hemiplegia
without loss of sensitivity and bulbar symptoms such as swallowing and speech impairment, vertigo, and altered consciousness. After Virchow's epoch-making work on embolism and thrombosis, all authors correctly described BAO as resulting from emboli and thrombosis based on arteriosclerosis instead of ossification of the arterial walls or inflammation. Around 1880, the clinical symptoms of BAO were obviously well-known to the experienced clinician. In this article we offer a chronological description of historical sources.

Essential mixed cryoglobulinaemia or type II cryoglobulinaemia is an important extrahepatic manifestation of chronic hepatitis C. Cryoglobulinaemia results in the deposition of immune complexes in small or medium-sized blood vessels leading to palpable purpura, arthralgia, renal disease and peripheral neuropathy.
Posterior
reversible encephalopathy syndrome (PRES) is a distinct phenomenon characterised by vasogenic oedema in the posterior circulation of brain. Cryoglobulinaemic vasculitis leading to spontaneous intracranial haemorrhage and PRES syndrome is rarely reported in the medical literature. In this report, we present an unusual case of spontaneous intracranial haemorrhage and PRES secondary to hepatitis C-associated cryoglobulinaemia presenting as right dense
hemiplegia
. Prompt institution of plasmapheresis resulted in successful resolution of symptoms in our patient, followed by full neurological recovery. To the best of our knowledge, this case describes the first successful use of plasmapheresis in alleviating neurological complications resulting from cryoglobulinaemic vasculitis and PRES secondary to chronic hepatitis C.

Posterior
drooling, which can lead to substantial respiratory morbidity, including unexplained lung diseases and recurrent pneumonia, is an important issue in the rehabilitation unit. There are various treatment options for posterior drooling, including pharmacologic therapy, oral motor or behavioral therapy, biofeedback, local glandular injection of botulinum toxin, irradiation, and surgery. Among them, nebulized glycopyrrolate has the following advantages: It is noninvasive and is relatively free of central adverse effects because it does not cross the blood-brain barrier unlike other anticholinergics. Although there has been one case report regarding the effectiveness of nebulized glycopyrrolate for drooling in a motor neuron patient, there have not been any reports on its effectiveness for posterior drooling. Herein, we report two cases (an 82-year-old male bilateral hemiplegic stroke patient and a 1-year-old female cerebral palsy infant with bilaterally spastic
hemiplegia
of posterior drooling treated with nebulized glycopyrrolate) and identify salivary aspiration and the effect of nebulized glycopyrrolate using radionuclide salivagram. Considering its advantages and effectiveness, nebulized glycopyrrolate should be considered as one of the reliable methods to manage posterior drooling in patients with impaired cognition or swallowing difficulties, such as severe brain injury.
