A Therapeutic Experience of Rapid Progressive HTLV-1 Associated Myelopathy in a Convalescent Rehabilitation Ward：A Case Report / The Japanese Journal of Rehabilitation Medicine

The patient was a 76-year-old woman who developed involuntary movements in both hands and gait disorder. Weakness in both lower limbs gradually worsened, and she was referred to our hospital. Neurological findings included spastic paraplegia, deep sensory disturbance, sensory ataxia, and bladder and bowel dysfunction. Approximately 4 months after the onset, she became unable to walk independently and had to use a walker. MRI showed a long spinal cord lesion extending from the cervical to thoracic spinal cord. Blood and spinal fluid samples tested positive for anti-human T-cell leukemia virus type 1 (HTLV-1) antibodies. Given these findings and subacute course, she was diagnosed with rapidly progressive HTLV-1 associated myelopathy (HAM). High levels of neopterin and CXCL10 in the cerebrospinal fluid suggested high disease activity；thus, she underwent steroid pulse therapy followed by treatment with maintenance oral prednisolone in our convalescent rehabilitation ward. After approximately 3 months of muscle strength training, mainly for the trunk muscle and the proximal muscle of the lower limbs, and balance exercise, she was able to walk independently and her activities of daily living (ADL) and instrumental ADL (IADL) improved；however, dysuria persisted. The use of clean intermittent self-catheterization instead of indwelling urethral catheter improved her quality of life (QOL). Although rapidly progressive HAM is generally associated with poor prognosis, steroid therapy combined with comprehensive rehabilitation treatment was effective in the present case.

Neuronopatía sensitiva: Su reconocimiento y tratamiento temprano / Sensory neuronopathy. Its recognition and early treatment

Las neuronopatías o ganglionopatías sensitivas, o enfermedades del ganglio dorsal, representan un subgrupo de enfermedades del sistema nervioso periférico, frecuentemente asociadas a trastornos disinmunes o paraneoplásicos, y a agentes tóxicos. Los pacientes típicamente presentan ataxia temprana, pérdida de los reflejos osteotendinosos y síntomas sensitivos positivos, presentes tanto en partes proximales como distales del cuerpo. Estudiamos retrospectivamente 10 casos con un diagnóstico final de neuronopatía sensitiva. El síntoma de presentación fue el de una neuropatía sensitiva de curso subagudo en todos los casos, con parestesias en el 100% de los casos. Otras manifestaciones fueron: hipoestesia (10/10), ataxia de la marcha (8/10), síntomas autonómicos (3/10) y parestesias periorales (3/10). La electrofisiología mostró un patrón de compromiso sensitivo axonal, con respuestas motoras normales. El diagnóstico final fue neuronopatía sensitiva adquirida en todos, asociada a síndrome de Sjögren en dos, a lupus eritematoso en uno, a artritis reumatoidea en uno, a cáncer en dos (paraneoplásica) e idiopática en cuatro. En los casos paraneoplásicos, los tumores fueron un carcinoma de pulmón de células pequeñas (con anticuerpos anti-Hu positivos) y un carcinoma epidermoide de pulmón. Ocho pacientes fueron tratados con inmunoterapia, con altas dosis de metilprednisolona endovenosa y/o con inmunoglobulina endovenosa; con pobre respuesta en cuatro casos, mejoría neurológica en cinco, y sin cambios en uno. El presente trabajo muestra el patrón clinico y electrofisiológico de las neuronopatías sensitivas subagudas, y la relevancia de un tratamiento temprano.

Sensory neuronopathies or ganglionopathies, or dorsal root ganglion disorders, represent a subgroup of peripheral nervous system diseases, frequently associated with dysinmune or neoplastic disorders and with toxic agents. A degeneration of both central and peripheral sensory proyections is present. Patients typically show early ataxia, loss of deep tendon reflexes and positive sensory symptoms present both in proximal and distal sites of the body. We retrospectively studied 10 cases with a final diagnosis of sensory neuronopathy. Sensory neuropathy was the presenting symptom and the course was subacute in all cases. Paresthesias in upper limbs were a predominant manifestation (100%). Other manifestations included: hypoesthesia (10/10), gait ataxia (8/10), autonomic symptoms (3/10) and perioral paresthesias (3/10). Electrophysiology showed sensory axonal neuronal pattern, with normal motor responses. Final diagnosis was acquired sensory neuronopathy in all patients, associated with Sjögren’s syndrome in 2, with lupus erythematosus in 1, with rheumatoid arthritis in 1, with a cancer in 2 (paraneoplastic) and idiopathic in 4. In paraneoplastic cases, the tumor was small cell lung cancer in 1 (with positive anti-Hu antibodies), and epidermoid lung cancer in the other. Eight patients were treated with immunotherapy, high dose intravenous methylprednisolone and/or intravenous immunoglobulin; with poor response in 4 cases, neurologic improvement in 5, and without any change in 1 patient. The present work shows the typical clinical and electrophysiological pattern of subacute sensory neuronopathy, and the relevance of early treatment.

Polirradiculopatía inflamatoria crónica sensitiva / Chronic inflammatory sensory polyradiculopathy

La polirradiculopatía inflamatoria crónica sensitiva es una entidad definida, frecuentemente subdiagnosticada y potencialmente tratable. Debe ser sospechada en pacientes con ataxia sensitiva, estudios de conducción nerviosa normales y una resonancia magnética que muestre engrosamiento y realce con gadolinio de las raíces lumbosacras. Presentamos el caso de un hombre de 57 años de edad con marcada ataxia sensitiva en pierna izquierda. Al examen físico presentaba fuerza conservada, reflejos osteotendinosos disminuidos, tacto fino y superficial reducidos por debajo de las rodillas; abatiestesia y apalestesia en ambos pies. Los estudios de conducción nerviosa eran normales, los potenciales evocados somatosensitivos tibiales con ausencia de respuesta bilateral. El líquido cefalorraquídeo presentaba hiperproteinorraquia sin células. La resonancia magnética mostró engrosamiento y realce con gadolinio de las raíces lumbosacras. El paciente fue tratado con inmunoglobulina endovenosa (IgEV) a 2 g/kg durante 5 días, con buena respuesta. La evolución clínica, la hiperproteinorraquia, el realce de raíces en la resonancia magnética, la buena respuesta a la inmunoterapia y la exclusión de otras causas de ataxia sensitiva fueron compatibles con el diagnóstico de polirradiculopatía inflamatoria crónica sensitiva. Para el diagnóstico de esta enfermedad se requiere la identificación del compromiso aislado de las raíces sensitivas.

Chronic inflammatory sensory polyradiculopathy is a defined entity, frequently underdiagnosed, and potentially treatable. It must be suspected in patients with sensory ataxia, normal nerve conduction studies, and MRI with thickened lumbosacral nerve roots and gadolinium enhancement. We present the case of a 57-year-old man with marked sensory ataxia on his left leg. Examination showed normal strength, decreased knee and ankle jerks. Light touch and pinprick sensations were reduced below the knees. Vibration and joint position sense were absent at the feet. Nerve conduction studies were normal. Tibial sensory evoked potentials disclosed absent responses bilaterally. CSF was acellular with elevated protein. Lumbosacral magnetic resonance showed thickening of roots, with gadolinium enhancement. The patient was treated with IV-Ig, 2 g/kg, for 5 days with improvement of symptoms. The clinical course, elevated CSF protein, the evidence of root enhancement on the MRI, good response to immunotherapy, and the exclusion of other causes of sensory ataxia, were compatible with the diagnosis of chronic inflammatory sensory polyradiculopathy. To diagnose this disease the identification of isolated involvement of the sensory roots is required.

Rehabilitation of Sensory Ataxic Acute Guillain-Barre Syndrome:A Case Study / 中国康复理论与实践

Objective To observe the effect of comprehensive rehabilitation based on motor control on sensory-ataxic acute Guillain-Barre syndrome. Methods A patient with sensory-ataxic acute Guillain-Barre syndrome was treated with kinesitherapy based on motor con-trol, included proprioceptive neuromuscular facilitation, coordination training, functional training, balance training, as well as sensory stimu-lation on the end of arms and legs, recumbent cross trainer therapy and cycle therapy for 2 months. Results After treatment, the score of In-ternational Cooperative Ataxia Rating Scale (ICARS) decreased 36 points, activities of daily living increased 9 points, Berg Balance Scale increased 9 points, and modified Barthel Index increased 50 points. Conclusion The comprehensive rehabilitation based on motor control is effective on this patient, but more cases and systematic curative effect evaluation are needed.

Paraneoplastic Syndrome with Sensory Polyneuropathy : A Report on Rehabilitation in Two Cases / The Japanese Journal of Rehabilitation Medicine

We report two cases of paraneoplastic syndrome with sensory polyneuropathy. Case one showed numbness of the upper and lower extremities before a diagnosis of small cell carcinoma was made. Case two showed the same symptoms coincidentally with a recurrence of ovarian cancer. In both cases, Romberg's sign was positive, ataxic gait was noted, and the patient's skill movement was disturbed. Sensory nerve action potentials were not evoked in any of the nerves. Compound muscle action potential and motor conduction velocity were at the lower limits of normal. The neurological abnormalities did not resolve in spite of medical treatments. In these two cases, the loss of sensory neurons due to a lesion of the dorsal root ganglia was suggested. The loss of sensory feedback might lead to muscle weakness and fatigue, so they tend to be disused. For long-term rehabilitation management in these two cases, we suggested a regular exercise program to prevent muscle weakness.
