Abstract
Trigeminal neuropathies (TNs) are well recognized disorders characterized and manifesting as skin and mucosal numbness in the region innervated by the trigeminal nerve. Facial numbness indicates trigeminal sensory alteration affecting the trigeminal system. TNs always pose differential location difficulties as multiple diseases are capable of producing them: they can be the result of traumatism, tumors, or diseases of the connective tissue, infectious or demyelinating diseases, or may be of idiopathic origin. Their importance is explained by the fact that TN may represent the first manifestation of tumor disease, or of relapse in patients with prior neoplastic processes. As such, these manifestations are ominous, and patient life expectancy is often short. The clinical exploration reveals a loss of sensitivity in the cutaneous territory corresponding to the affected nerve, which can be partial (hypoesthesia) or complete (anesthesia). The sensory defect is occasionally associated with hyperesthesia (i.e., the patient suffers a decrease in sensory perception, but when sensation is perceived, it may cause considerable discomfort). Complementary studies are needed to establish the etiologic diagnosis, with laboratory tests to discard the possible causative diseases underlying the trigeminal neuropathy, and the opportune radiographic examinations in the form of plain X-rays or a routine cranial computed tomography scan.

Abstract
Peripheral neuropathy is common in patients with Sjögren's syndrome (SS), but its precise prevalence is unknown. Most prior studies were conducted at neurology or rheumatology specialty clinics and likely selected for a more severely affected population. We evaluated 22 SS patients and 10 controls for evidence of neuropathy in an outpatient setting at a regional meeting of the Sjögren's Syndrome Foundation. We performed neurological examinations and nerve conduction studies (NCSs) and measured serum antinuclear antibody (ANA) and SS-A and SS-B antibody levels. Participants filled out a questionnaire pertaining to symptoms, diagnosis, and treatment. We found that signs and symptoms related to small axons were more common in patients with SS than in controls. Complaints of painful distal paresthesias in the feet were noted in 59% of patients but in only 10% of controls, and of abnormal sweating in 41% and 0%, respectively. Examination revealed decreased pinprick sensation in 64% of patients with SS, but in only 30% of controls. Overall, 45% of the patients but none of the controls were thought to have an isolated small-fiber neuropathy. Large-fiber dysfunction (as measured by testing vibration, deep tendon reflexes, and NCSs) was similar between the two groups. We conclude that small-fiber neuropathy is common in patients with SS.

Abstract
Of 20 consecutive patients with Sjögren neuropathy, 16 (80%) presented with burning feet and 12 (60%) with non-length-dependent sensory symptoms. Leg and thigh skin biopsies, performed in 13 patients, including 7 with normal electrophysiology, showed either reduced epidermal nerve fiber (ENF) density or abnormal morphology. ENF loss was frequently non length dependent, suggesting that patients with this disorder commonly have a small-fiber sensory neuronopathy rather than a "dying-back" axonopathy.

Abstract
We assessed the clinicopathological features of 92 patients with primary Sjögren's syndrome-associated neuropathy (76 women, 16 men, 54.7 years, age at onset). The majority of patients (93%) were diagnosed with Sjögren's syndrome after neuropathic symptoms appeared. We classified these patients into seven forms of neuropathy: sensory ataxic neuropathy (n = 36), painful sensory neuropathy without sensory ataxia (n = 18), multiple mononeuropathy (n = 11), multiple cranial neuropathy (n = 5), trigeminal neuropathy (n = 15), autonomic neuropathy (n = 3) and radiculoneuropathy (n = 4), based on the predominant neuropathic symptoms. Acute or subacute onset was seen more frequently in multiple mononeuropathy and multiple cranial neuropathy, whereas chronic progression was predominant in other forms of neuropathy. Sensory symptoms without substantial motor involvement were seen predominantly in sensory ataxic, painful sensory, trigeminal and autonomic neuropathy, although the affected sensory modalities and distribution pattern varied. In contrast, motor weakness and muscle atrophy were observed in multiple mononeuropathy, multiple cranial neuropathy and radiculoneuropathy. Autonomic symptoms were often seen in all forms of neuropathy. Abnormal pupils and orthostatic hypotension were particularly frequent in sensory ataxic, painful, trigeminal and autonomic neuropathy. Unelicited somatosensory evoked potentials and spinal cord posterior column abnormalities in MRI were observed in sensory ataxic, painful and autonomic neuropathy. Sural nerve biopsy specimens (n = 55) revealed variable degrees of axon loss. Predominantly large fibre loss was observed in sensory ataxic neuropathy, whereas predominantly small fibre loss occurred in painful sensory neuropathy. Angiitis and perivascular cell invasion were seen most frequently in multiple mononeuropathy, followed by sensory ataxic neuropathy. The autopsy findings of one patient with sensory ataxic neuropathy showed severe large sensory neuron loss paralleling to dorsal root and posterior column involvement of the spinal cord, and severe sympathetic neuron loss. Degrees of neuron loss in the dorsal and sympathetic ganglion corresponded to segmental distribution of sensory and sweating impairment. Multifocal T-cell invasion was seen in the dorsal root and sympathetic ganglion, perineurial space and vessel walls in the nerve trunks. Differential therapeutic responses for corticosteroids and IVIg were seen among the neuropathic forms. These clinicopathological observations suggest that sensory ataxic, painful and perhaps trigeminal neuropathy are related to ganglioneuronopathic process, whereas multiple mononeuropathy and multiple cranial neuropathy would be more closely associated with vasculitic process.

Abstract
Sensory ganglionopathies have a frequent association with neoplastic disorders (paraneoplastic subacute sensory neuronopathy, or SSN) or dysimmune disorders (Sjögren's syndrome, SS; Miller Fisher syndrome; and Bickerstaff's brainstem encephalitis, BBE), with drugs, such as cisplatin or pyridoxine, and with inherited disorders with degeneration of dorsal root ganglion cells. Unsteady gait and pseudoathetoid movements of the hand are the distinctive signs encountered in these disorders. The chronic disorders are characterized by non-length-dependent abnormalities of sensory nerve action potentials (SNAPs) and differ from other sensory neuropathies in showing a global, rather than distal, decrease in SNAP amplitudes. This review focuses on recent advances in defining the mechanisms involved in sensory ganglionopathies. Specific topics include a summary of their clinical features, pathological findings, and immunopathology. In SSN, early diagnosis by the detection of anti-Hu antibodies and early treatment of the cancer gives the best chance of stabilizing the disorder. In SS sensory ganglionitis, response to treatment has been disappointing, but immunomodulating treatments are emerging. The immunological profile common to BBE and Fisher syndrome supports a common pathogenesis. In toxic sensory neuronopathy, no treatment is available. The differential diagnosis involves separating sensory ganglionopathies from other ataxic polyneuropathies, such as infectious neuropathies, sensory neuropathies with various autoantibodies, and the neuropathies seen in celiac disease.

Abstract
The relationship between neuropathy and Sjögren syndrome has been predicated largely on sicca symptoms or serological abnormalities rather than salivary gland pathology. We reviewed consecutive neuropathy patients who had had a lip biopsy to identify features of the neuropathy that were associated with a positive lip biopsy suggesting Sjögren syndrome. Twenty of 54 neuropathy patients were biopsy positive; 13 had a painful or nonspecific sensory neuropathy and only 4 were ataxic. Sicca symptoms were not associated with a positive biopsy (P = 0.14). Serological abnormalities were found more often in the biopsy-positive group (P = 0.008), but anti-Sjögren syndrome A or B (anti-SSA or SSB) antibodies were detected in only 30%. There were no other clinical or electromyographic (EMG) features associated with a positive biopsy. From this experience, we conclude that: (1). most patients with neuropathy and a positive lip biopsy for Sjögren syndrome have a painful, distal, sensory axonal neuropathy; (2). there are no clinical or EMG features that are predictive of a positive lip biopsy; (3). ataxic neuropathy is uncommon; and (4). the lack of sicca symptoms or anti-SSA or SSB antibodies in patients with neuropathy does not exclude Sjögren syndrome based upon salivary gland pathology.

Abstract
Auto-antibodies cross-reacting with L-type voltage-gated calcium channels (VGCCs) have been described in primary Sjögren's syndrome (pSS), and may mediate the cardiac defects in neonates born to mothers with pSS. L-type VGCCs are also present in autonomically innervated tissues. Therefore, the aim of this project was to investigate a role for anti-VGCC antibodies and antibodies to alpha(1)-adrenoceptors or P(2X)-purinoceptors in the autonomic dysfunction that occurs in pSS. Contraction of the sympathetically innervated vas deferens in response to stimulation of the muscle by an alpha(1)-adrenoceptor agonist (phenylephrine) or a P(2X)-purinoceptor agonist (alpha,beta-methylene ATP) was measured in the absence and presence of 2% serum. Contractions produced by phenylephrine and by alpha,beta-methylene ATP were abolished by nicardipine, demonstrating that they are coupled to calcium influx through L-type VGCCs. Serum from patients with pSS or from healthy controls did not significantly alter the L-type channel-dependent responses of smooth muscle to agonist stimulation. We therefore conclude that pSS serum does not contain autoantibodies that functionally inhibit L-type VGCCs, alpha(1)-adrenoceptors or P(2X)-purinoceptors in smooth muscle and that such autoantibodies cannot explain the autonomic dysfunction in pSS.

Abstract
OBJECTIVE To determine if patients with systemic lupus erythematosus (SLE) may have a peripheral neuropathy involving unmyelinated and small, myelinated nerve fibers, by immunostaining epidermal nerve fibers (ENF) in skin biopsy samples for the panaxonal marker, protein gene product 9.5 (PGP 9.5). METHODS Fifteen consecutive and nonselected SLE patients and 15 age- and sex-matched controls were included in the study. The age of the patients ranged from 25 years to 65 years, with a mean +/- SD age of 47.3 +/- 10.2 years and a disease duration of 2-28 years (mean +/- SD 14.8 +/- 8.6 years). Two 3-mm skin biopsy samples were obtained with a punch needle approximately 10 cm superior to the lateral malleolus of the right leg and immunostained with 0.1% rabbit polyclonal antibodies to human PGP 9.5. The number of ENF per millimeter was counted and recorded as the mean +/- SD of counts in six 50-microm sections, 3 from each of the 2 biopsy samples. RESULTS The mean number of ENF per mm in patients with SLE was 8.0 +/- 1.5 (range 5.0-9.9), while the matched controls had 12.2 +/- 3.8 ENF per mm (range 6.8-18.6) (P = 0.0006). CONCLUSION This study indicates that a small fiber involvement in patients with SLE may be responsible for the prevalent neuropathic symptoms and impaired warm sense that is observed in such patients.

Abstract
Autonomic failure and proximal skeletal myopathy are rare features of the Sjögren syndrome (SS). We describe a 51-year-old woman with primary SS who had development of esophageal dysmotility, urinary retention, severe orthostatism, and skeletal myopathy during a 3-month period after the diagnosis of SS. Her symptoms and signs responded well to corticosteroid therapy. Although dysfunction of the peripheral nervous system has a prevalence rate of 20% in patients with SS, most commonly the nerve dysfunction is a sensory deficit, and autonomic neuropathy is less frequent. Autonomic neuropathy due to SS may be underreported. The cause of our patient's myopathy remains undetermined. We speculate that the myopathy was due to either a form of polymyositis or an immune-mediated neuropathy with muscle involvement.

Abstract
Quantitative sensory testing (QST) has been used clinically for the last two decades, yielding a substantial number of publications regarding these applications. In this review we tried to amass together the major findings of these publications into one monograph, excluding those dealing with pain. This was done with the aim of assisting clinicians in the better use of QST techniques for the benefit of their patients.

Abstract
Systemic lupus erythematosus (SLE) frequently involves the central nervous system (CNS), but to a considerably lesser degree leads to peripheral neuropathy as measured by conventional nerve conduction velocity studies. Neuropathic symptoms are, however, frequently reported. Abnormalities of other nerve fibers than the large myelinated nerves might thus be responsible for such phenomena. Three age matched groups of 44 patients with SLE, 50 patients with rheumatoid arthritis (RA) and 45 healthy controls were investigated with quantitative sensory thermotesting. Warm detection thresholds (WDT) and heat pain detection thresholds (HPDT) were found significantly higher in SLE compared to RA and controls. There were no differences between the RA and the control group. In the SLE group no association to disease duration, medication or CNS abnormalities were found. Neuropathic symptoms and vibration thresholds showed weak associations to WDT. These findings imply that there is an impairment of C-fibre function in SLE. This small fibre neuropathy is probably not part of a generalized diffuse polyneuropathy also affecting large fibres, although this can not be ruled out completely by this study.
