Patients at various stages of human immunodeficiency virus (HIV) infection require rehabilitation services. These patients present problems for each of the disciplines in a rehabilitation team, and all team members must confront the psychosocial and ethical issues involved with the disease. Patients with HIV infection may have polyneuropathy with multisystem involvement, including dysphagia, autonomic dysfunction, respiratory failure, bowel and bladder dysfunction, generalized weakness, a painful sensory neuropathy, and depression. Guidelines are presented for determining if inpatient rehabilitation or other settings are appropriate. Case management is a valuable strategy for the rehabilitation of patients with this complicated disorder.

A two-year-old rough collie bitch with a five-week history of excess salivation, coughing and dysphagia was examined. The dog had bilateral sensory loss over the whole trigeminal field while motor function of the fifth cranial nerve was preserved. No other neurological abnormalities were detected. The dog was observed over 18 months during which the condition did not progress. It was destroyed 18 months after the onset of trigeminal signs following development of a systemic illness, refractory to treatment and unrelated to the neurological signs. Pathological abnormalities were limited to the three major branches of both fifth nerves and the gasserian ganglia. There was partial loss of myelinated nerve fibres in each branch and also in the spinal tract of the fifth nerve in the brain stem. It was considered that the primary abnormality was in the gasserian ganglion and that the fibre loss was secondary to the neuronal lesion in the ganglia. The motor nucleus of the fifth nerve was normal. No cause could be found for this isolated sensory neuropathy of the trigeminal nerve.

Cacogeusia, being the patients' main complaint, is reported as a new symptom of amyloidosis, probably caused by a peripheral sensory neuropathy. A case is presented of a patient with weight loss, dysphagia, macroglossia and taste disturbances, due to amyloidosis associated with a plasma cell dyscrasia. The importance of oral manifestations in amyloidosis is discussed.

Spinocerebellar ataxia type 4 (SCA4), also known as 'hereditary ataxia with sensory neuropathy', represents a very rare, progressive and untreatable form of an autosomal dominant inherited cerebellar ataxia (ADCA). Due to a lack of autopsy cases, no neuropathological or clinicopathological studies had yet been performed in SCA4. In the present study, the first available cerebellar and brainstem tissue of a clinically diagnosed and genetically-confirmed German SCA4 patient was pathoanatomically studied using serial thick sections. During this systematic postmortem investigation, along with an obvious demyelinization of cerebellar and brainstem fiber tracts we observed widespread cerebellar and brainstem neurodegeneration with marked neuronal loss in the substantia nigra and ventral tegmental area, central raphe and pontine nuclei, all auditory brainstem nuclei, in the abducens, principal trigeminal, spinal trigeminal, facial, superior vestibular, medial vestibular, interstitial vestibular, dorsal motor vagal, hypoglossal, and prepositus hypoglossal nuclei, as well as in the nucleus raphe interpositus, all dorsal column nuclei, and in the principal and medial subnuclei of the inferior olive. Severe neuronal loss was seen in the Purkinje cell layer of the cerebellum, in the cerebellar fastigial nucleus, in the red, trochlear, lateral vestibular, and lateral reticular nuclei, the reticulotegmental nucleus of the pons, and the nucleus of Roller. In addition, immunocytochemical analysis using the anti-polyglutamine antibody 1C2 failed to detect any polyglutamine-related immunoreactivity in the central nervous regions of this SCA4 patient studied. In view of the known functional role of affected nuclei and related fiber tracts, the present findings not only offer explanations for the well-known disease symptoms of SCA4 patients (i.e. ataxic symptoms, dysarthria and somatosensory deficits), but for the first time help to explain why diplopia, gaze-evoked nystagmus, auditory impairments and pathologically altered brainstem auditory evoked potentials, saccadic smooth pursuits, impaired somatosensory functions in the face, and dysphagia may occur during the course of SCA4. Finally, the results of our immunocytochemical studies support the concept that SCA4 is not a member of the CAG-repeat or polyglutamine diseases.

We describe a patient who developed an ataxic sensory syndrome associated with xerophthalmia and progressive dysphagia with regurgitation. Electrophysiological findings were consistent with an axonal sensory neuropathy, and superficial peroneal nerve biopsy showed a reduction in number of myelinated fibers with epineurial inflammation. Rheumatoid factor, anti-SSA/SSB and antinuclear antibodies were positive and a diagnosis of Sjogren's syndrome was made. An endoscopic investigation revealed esophageal achalasia. We suggest that there may be a common autoimmune mechanism directed to different targets on the basis of this rare association.

Allgrove syndrome is a rare autosomal recessive disorder characterised by childhood onset, alacrima, oesophageal achalasia, adrenocortical insufficiency, neurological and occasionally autonomic involvement. Although the disease has been associated with mutations in the ALADIN gene on chromosome 12q13, it is genetically heterogeneous. The case we report is interesting because of its onset in adulthood, long duration of disease and prominent neurological dysfunctions. After the onset of neurological abnormalities the diagnosis went unrecognised for years until the patient presented for evaluation of dysphagia. The presence of achalasia with dysphagia, adrenal insufficiency, reduced tear production, optic atrophy and peripheral motor-sensory neuropathy with axonal loss led us to clinically diagnose Allgrove syndrome even though a genetic study showed no mutations in the ALADIN gene exons. The case we report shares many clinical features with Allgrove syndrome and, even with the limitations of a single case, underlines the variability in this syndrome and the need for appropriate investigations along with a multidisciplinary approach.

Variations in the mitochondrial helicase Twinkle (PEO1) gene are usually associated with autosomal dominant chronic progressive external ophthalmoplegia (PEO). We describe five patients from two unrelated Alsatian families with the new R374W variation in the Twinkle linker region who progressively developed an autosomal dominant multisystem disorder with PEO, hearing loss, myopathy, dysphagia, dysphonia, sensory neuropathy, and late-onset dementia resembling Alzheimer's disease. These observations demonstrate that Twinkle variations in the linker domain alter cerebral function and further implicate disrupted mitochondrial DNA integrity in the pathogenesis of dementia.

Familial dysautonomia (FD) is an autosomal recessive disorder characterized by autonomic and sensory neuropathy. Owing to pervasive dysfunction, the disease has protean clinical manifestations, affecting the ocular, gastrointestinal, pulmonary, orthopedic, vasomotor, and neurologic systems. The gastrointestinal perturbations, including dysphagia, gastroesophageal dysmotility, gastroesophageal reflux, and vomiting crises, are among the earliest signs. Here, we present the first 3 instances of gastric ulcers in patients with FD and discuss their common presenting features and the special management that was required.

Tonsillar metastatic small cell lung cancer (SCLC) is rare, while anti-Hu antibodies are frequently found in SCLC. A 66-year-old man was admitted to our hospital with painful dysesthesia and muscle weakness in the distal extremities for over 1 year, progressive dysphagia for over 1 month, and severe cough and dyspnea for over 1 week. He was diagnosed with SCLC accompanied by tonsillar metastasis and anti-Hu antibody-associated paraneoplastic sensory neuropathy (PSN). The patient tolerated 6 cycles of sequential chemoradiotherapy and gradually recovered. The patient's disease remained in remission 2 years after the diagnosis with a remarkable reduction of tumor burden and a persisting high titer of anti-Hu antibodies. To our knowledge, this is the first case of tonsillar metastatic SCLC accompanied by anti-Hu antibody-associated PSN, whereby the anticancer immune response was presumed to play a vital role in disease control. Unilateral tonsillar metastasis of SCLC accompanied by anti-Hu antibody-associated PSN can occur and in certain circumstances, may have a favorable prognosis.

Gain-of-function mutations in the SCN10A gene (encoding the Nav1.8 voltage gated sodium channel) have been reported in a small number of patients. All presented with predominantly painful sensory neuropathy, congruent with the expression of Nav1.8 in nociceptive sensory neurons of the dorsal root ganglion. Only a few had mild autonomic symptoms, including dry eyes and mouth, orthostatic dizziness, palpitations, diarrhea and constipation. The underlying mechanism of the autonomic symptoms in these patients is unclear. We describe a 37-year-old woman with severe progressive gastroparesis and diffuse painful small fiber sensory neuropathy that started at age 32. Due to the severe dysphagia she could not ingest solid food, and lost eight kilograms. The gastroparesis was documented by esophageal manometry and gastric scintigraphy. The neuropathic pain started distally and then intensified and spread to most body areas. The patient harbored a novel heterozygous mutation: c.G4915A:p.D1639N in the SCN10A gene. To the best of our knowledge, this is the first description of such a phenotype due to a Nav1.8 mutation. Thus, our study expands the clinical spectrum of Nav1.8 associated disorders, and suggests that mutations in this sodium channel should be considered in patients with gastrointestinal motility dysfunction and painful neuropathy.
