We report a case of a 53-year-old male with traumatic cervical spinal cord injury (SCI). He could not maintain a standing position because of painful spasticity in his lower limbs. A magnetic resonance imaging and electromyography indicated chronic lumbosacral radiculopathy, explaining his chronic low back pain before the injury. For diagnostic as well as therapeutic purposes, transforaminal epidural steroid injection (ESI) to the right L5 root was performed. After the intervention, the spasticity decreased and his ambulatory function improved. This case illustrates that lumbar radiculopathy concomitant with a cervical SCI can produce severe spasticity and it can be dramatically improved by ESI.

A 50-year-old man with liver cirrhosis and esophageal varix for 3 years was diagnosed with hematemesis and treated for a bleeding varix. However, bleeding recurred 11 days later, and he developed drowsiness with left hemiparesis. His left upper and lower extremity muscle strengths based on the manual muscle test at the onset were grade 2/5 and 1/5, respectively. The Babinski sign was positive. His serum ammonia level was elevated to 129.9 µg/dL (normal, 20-80 µg/dL). Magnetic resonance imaging revealed restriction on diffusion and T2-hyperintensities with decreased apparent diffusion coefficient values in the bilateral frontoparietooccipital cortex. The effect was more severe in the right hemisphere and right parietooccipital cortices, which were compatible with hepatic encephalopathy. Although the patient's mental status recovered, significant left-sided weakness and sensory deficit persisted even after 6 months. Diffusion tensor tractography (DTT) performed 3 months post-onset showed decreased volume of the right corticospinal tract. We reported a patient with hepatic encephalopathy involving the corticospinal tract by DTT.
To obtain information on the socioeconomic, medical, and functional status of polio survivors, and to use these results as the preliminary data for establishing the middle-aged cohort of polio survivors.
The subjects were recruited based on the medical records of multiple hospitals and centers. They were assessed through a structured questionnaire over the phone. Post-poliomyelitis syndrome (PPS) was identified according to the specified diagnostic criteria. Differences between polio survivors with or without PPS were evaluated, and the risk factors for PPS were analyzed by the odds ratio (OR).
Majority of polio survivors were middle-aged and mean age was 51.2±8.3 years. A total of 188 out of 313 polio survivors met the adopted criteria for PPS based on the symptoms, yielding a prevalence of 61.6%. Mean interval between acute poliomyelitis and the development of PPS was 38.5±11.6 years. Female gender (OR 1.82; confidence interval [CI] 1.09-3.06), the age at onset of poliomyelitis (OR 1.75; CI 1.05-2.94), the use of orthoses or walking aids (OR 2.46; CI 1.44-4.20), and the history of medical treatment for paralysis, pain or gait disturbance (OR 2.62; CI 1.52-4.51) represented independent risk factors for PPS.
We found that the majority of Korean polio survivors entered middle age with many medical, functional, and social problems. Female gender, early age of onset of poliomyelitis, the use of orthoses or walking aids, and the history of medical treatment for paralysis, pain or gait disturbance were identified as the significant risk factors for PPS. A comprehensive and multidisciplinary plan should be prepared to manage polio survivors considering their need for health care services and the risk factors for late effects, such as PPS.

To identify the correlations between the location of multifidus atrophy and the level of lumbar radiculopathy.
Thirty-seven patients who had unilateral L4 or L5 radiculopathy were divided into 2 groups; the L4 radiculopathy (L4 RAD) group and the L5 radiculopathy (L5 RAD) group. Bilateral lumbar multifidus muscles at the mid-spinous process level of L4 vertebra (L4 MSP), the mid-spinous process level of L5 vertebra (L5 MSP), and the mid-sacral crest level of S1 vertebra (S1 MSC) were detected in T1 axial magnetic resonance imaging. The total muscle cross-sectional area of multifidus muscles (TMCSA) and the pure muscle cross-sectional area of multifidus muscles (PMCSA) were measured by a computerized analysis program, and the ratio of PMCSA to TMCSA (PMCSA/TMCSA) was calculated.
There were no significant differences in TMCSA between the involved and the uninvolved sides in both groups. PMCSA was only significantly smaller at the S1 MSC on the involved side as compared with the uninvolved side in the L5 RAD group. The ratio of PMCSA to TMCSA was the lowest at the L5 MSP on the involved side in the L4 RAD group and at the S1 MSC on the involved side in the L5 RAD group.
Our findings suggest that the most severe atrophy of multifidus muscle may occur at the mid-spinous process or mid-sacral crest level of the vertebra which is one level below the segmental number of the involved nerve root in patients with a single-level, unilateral lumbar radiculopathy.

The intrathecal chemotherapy with methotrexate and cytarabine arabinoside is used for the treatment and prophylaxis of the primary central nervous system lymphoma. The therapy may induce neurotoxicity including the cauda equina syndrome. We report a case of a 58-year-old man with the diffuse large B-cell lymphoma, who developed the cauda equina syndrome after the administration of intrathecal methotrexate and cytarabine arabinoside, as diagnosed by the electrodiagnostic, urodynamic, and radiologic approaches.

To investigate the factors affecting rehabilitation outcomes in children with congenital muscular torticollis (CMT).
We retrospectively reviewed the medical records of 347 patients who were clinically suspected as having CMT and performed neck ultrasonography to measure sternocleidomastoid (SCM) muscle thickness. Fifty-four patients met the inclusion criteria. Included were demographic characteristics as well as measurements of cervical range of motion (ROM), SCM muscle thickness, and the abnormal/normal (A/N) ratio, defined as the ratio of SCM muscle thickness on the affected to the unaffected side.
Subjects were divided into three groups depending on degree of cervical ROM (group 1A: ROM>60, n=12; group 1B: 60≥ROM>30, n=31; group 1C: ROM≤30, n=11), the SCM muscle thickness (Th) (group 2A: Th<1.2 cm, n=23; group 2B: 1.2≤Th<1.4 cm, n=18; group 2C: Th≥1.4 cm, n=13), and the A/N ratio (R) (group 3A: R<2.2, n=19; group 3B: 2.2≤R<2.8, n=20; group 3C: R≥2.8, n=15). We found that more limited cervical ROM corresponded to longer treatment duration. The average treatment duration was 4.55 months in group 1A, 5.87 months in group 1B, and 6.50 months in group 1C. SCM muscle thickness and the A/N ratio were not correlated with treatment duration.
Infants with CMT who were diagnosed earlier and had an earlier intervention had a shorter duration of rehabilitation. Initial cervical ROM is an important prognostic factor for predicting the rehabilitation outcome of patients with CMT.
