Clay-shoveler’s fractures are rare stress-type avulsion fractures of the spinous processes especially in sports. There have been two case reports that discussed clay-shoveler’s fractures in golf. A 36-year-old beginner golfer presented with a pain in the back after practicing golf swing. No fractures were detected using cervical radiography; however, computed tomography (CT) and magnetic resonance imaging (MRI) revealed T2∼T3 spinous process fractures. The patient was treated conservatively and his pain subsided. The mechanism of injury is speculated to that of clay-shoveler’s fractures. Therefore, if a golfer suffers persistent pain in the cervicothoracic region, clay-shoveler’s fracture is one possibility to consider.

OBJECTIVE: To quantitatively evaluate the side- and level-specific change of the multifidus muscle in unilateral radicular pain caused by lumbar disc herniation using magnetic resonance imaging (MRI).METHOD: Sixty-nine patients with L4-5 disc herniation who underwent electrodiagnostic study and spine MRI were enrolled and divided into the radiculopathy group (n=30) and the control group (n=39) according to the presence of L5 radiculopathy. The radiculopathy group was subdivided into the paraspinalis group (n=12) and the limb group (n=18) according to whether or not paraspinalis muscle was denervated. The cross-sectional area (CSA) and signal intensity (SI) of the multifidus muscle were measured bilaterally at L4-5 and L5-S1 middle intervertebral levels on axial T2-weighted MRI.RESULTS: There was no significant difference in the CSA of the multifidus muscle between the radiculopathy group and the control group. In the radiculopathy group, multifidus SI was greater than the control group on the affected side and below the level of herniation (p=0.015). In the subgroup comparison, affected side L5-S1 multifidus SI was significantly different between the paraspinalis group and the control group (p=0.001), but not between the limb group and the control group (p>0.05).CONCLUSION: Our findings suggest that quantitative measurement of multifidus SI may be indicative of the location of nerve root compromise through side- and level- specific changes.

Background: Pediatric patients with moyamoya disease are vulnerable to ischemic attacks following physical or emotional stress, such as those experienced during blood sampling. A central venous catheter might be beneficial for blood sampling, and a peripherally inserted central catheter (PICC) is a considerable option for central venous access. However, PICC insertion during anesthetic management is relatively rare.Case: Thirty cases of ultrasound-guided PICC insertion were performed in children undergoing surgery for moyamoya disease after anesthetic induction. Positioning was successful in 22 cases, and 5 were malpositioned. In three cases, the peripheral insertion failed. Adjustment of the insertion depth was performed in nine cases. No complications related to catheterization were observed during the procedure or the catheter indwelling period. Conclusions We report the successful use of PICC in children undergoing surgery for moyamoya disease with a considerable success rate and low incidence of malpositioning or complications.

OBJECTIVE: To investigate the presence of cranial neuropathy in patients with platinum-analogue chemotherapy using electrodiagnostic evaluations. METHODS: Thirty-nine patients whose chemotherapy was completed within a month and 40 control subjects were enrolled in the study. Electrodiagnostic evaluation was performed using sensory and motor nerve conduction studies and blink reflex studies, in addition to the two-point discrimination test. RESULTS: The chemotherapy group had significantly longer latencies of bilateral R1 responses (left p<0.001; right p<0.001) and greater distance in two-point discrimination (p<0.001) compared to the control group. In the subgroup with peripheral polyneuropathy, the left R1 (p=0.01), both R2i (left p=0.02; right p=0.03) and the left R2c (p=0.02) were prolonged relative to those without the polyneuropathy, and both R1 (left p<0.001; right p<0.001), R2i (left p=0.01; right p=0.03), and the left R2c (p=0.01) were prolonged relative to the controls. On the other hand, the subgroup without the polyneuropathy showed only prolongation of both R1 (left p=0.006; right p<0.001) relative to the controls. CONCLUSION: In the present study, comparison of blink reflex and two-point discrimination showed the likelihood of subclinical cranial neuropathy following platinum-analogue chemotherapy. Cranial neuropathy caused by platinum agents was more profound in patients with peripheral polyneuropathy and may be dependent on the cumulative dose of the drug. The blink reflex may be of value in detecting subclinical cranial neuropathy in patients undergoing platinum-analogue chemotherapy.

PURPOSE: Peripheral neuropathy (PN) is known as a major contributor of the worsening of ischemic symptoms and the foot ulceration in patients with peripheral arterial occlusive disease (PAOD). However, there are few studies reporting the prevalence and risk factors for PN in PAOD. This study aimed to evaluate these issues for PN and to establish the importance of screening as additional treatment target for PN in PAOD. MATERIALS AND METHODS: A total of 52 limbs with PAOD were enrolled from January 2011 to December 2012. PN was divided into radiculopathy, ischemic PN (IPN), and diabetic PN (DPN), based on electromyographic findings. We investigated the prevalence of overall PN and subtypes of PN and then analyzed the risk factors. RESULTS: The prevalence of overall PN in PAOD was 43 of 52 limbs (82.7%). In terms of subtypes of PN, the prevalence rate of radiculopathy and IPN was 30.8% and 23.1%, respectively. DPN showed in 22 limbs (73.3%) among 30 diabetic limbs. There was no significant correlation between each type of PN and ischemic symptoms. Our analysis showed that coronary artery disease (CAD) was a significant risk factor (P=0.01) for IPN, however, did not identify any significant risk factors for DPN. CONCLUSION: This present study indicated that most patients with PAOD had PN and CAD was a risk factor for IPN. In particular, PAOD with diabetes represented a higher prevalence for DPN. Our study suggests that PN should be evaluated and considered as another treatment target in patients with PAOD.

OBJECTIVE: To evaluate the validity of the Test of Infant Motor Performance (TIMP) and general movements (GMs) assessment for predicting Alberta Infant Motor Scale (AIMS) score at 12 months in preterm infants. METHODS: A total of 44 preterm infants who underwent the GMs and TIMP at 1 month and 3 months of corrected age (CA) and whose motor performance was evaluated using AIMS at 12 months CA were included. GMs were judged as abnormal on basis of poor repertoire or cramped-synchronized movements at 1 month CA and abnormal or absent fidgety movement at 3 months CA. TIMP and AIMS scores were categorized as normal (average and low average and >5th percentile, respectively) or abnormal (below average and far below average or < 5th percentile, respectively). Correlations between GMs and TIMP scores at 1 month and 3 months CA and the AIMS classification at 12 months CA were examined. RESULTS: The TIMP score at 3 months CA and GMs at 1 month and 3 months CA were significantly correlated with the motor performance at 12 months CA. However, the TIMP score at 1 month CA did not correlate with the AIMS classification at 12 months CA. For infants with normal GMs at 3 months CA, the TIMP score at 3 months CA correlated significantly with the AIMS classification at 12 months CA. CONCLUSION: Our findings suggest that neuromotor assessment using GMs and TIMP could be useful to identify preterm infants who are likely to benefit from intervention.

Post-stroke spasticity is a common complication that causes limitations of function, pain and decrement of the quality of life. Although botulinum toxin injection and anti-spastic medications are effective and widely used for the management of post-stroke spasticity, clinical applications are often limited in stroke patients because of their invasiveness and systemic side effects. Alternatively, we performed upper limb muscle-belly extracorporeal shock wave therapy (ESWT) to resolve problematic spasticity in two subacute stroke patients. Serial quantitative ultrasonographic measurements of spastic muscle were conducted to investigate the rheological changes in chronological order by echogenicity comparison. After 4 sessions of weekly ESWT, gradual decrements of clinical spasticity parameters and muscle echogenicity were observed and lasted for 1 week after the cessation of the therapy. ESWT may be a useful alternative management for treating post-stroke spasticity.

Kennedy’s disease (KD) or bulbospinal muscular atrophy is an uncommon x-linked recessive genetic disorder. Its diagnosis is challenging due to its wide array of clinical manifestations and difficulty distinguishing it from other motor neuron diseases.Thus, diagnosis is confirmed through DNA testing. 52-year-old male patient presented to the hospital with chronic low back pain (LBP) and muscle weakness. The patient had mild weakness in some proximal muscles, increased deep tendon reflex.Lumbar spine magnetic resonance imaging (MRI) showed degenerative changes. Motor nerve conduction test results showed close to the normal. Sensory nerve conduction test results showed decreased latency and amplitude in most nerves. Needle electromyography revealed fasciculation potentials, diffuse fibrillation potentials, and positive sharp waves were detected. Thus, molecular genetic testing was performed. Consequently, KD was diagnosed. These results suggest the importance of detailed history taking and neurological examination even for patients with chronic LBP to rule out severe diseases.

Class III malocclusion with mandibular protrusion can be divided into skeletal and pseudo malocclusion due to tooth displacement.For skeletal malocclusion, favorable treatment results can be obtained by establishing an appropriate vertical and horizontal intermaxillary relationship in order to secure a restoration space and obtain aesthetic and functional results. In this case, complete mouth rehabilitation was performed using an implant and a fixed prosthesis in a patient with mandibular protrusion and anterior teeth wear and reduced occlusal vertical dimension. After cast analysis and digital diagnosis, a provisional restoration with increased vertical dimension was fabricated to secure posterior support and evaluate stable centric occlusion. With the definitive prosthesis reflecting the provisional restoration, favorable function and aesthetics were obtained.
