Prolonged intubation is known to bring on postextubation dysphagia (PED) in some patients. We have noted that there were some studies to investigate specific type and pattern of PED, which showed large variety of different swallowing abnormalities as mechanisms of PED that are multifactorial. There are several options of treatment in accordance with the management of these abnormalities. A botulinum toxin (BoT) injection into the upper esophageal sphincter (UES) can improve swallowing functions for patients with this disorder, by working to help the muscle relax. In this case, the conventional treatment was not effective in patients with PED, whereas the BoT injection made a great improvement for these patients. This study suggests that the UES pathology could be the main cause of PED.

To delineate the effect of early cranioplasty on the recovery of cognitive and functional impairments in patients who received decompressive craniectomy after traumatic brain injury or spontaneous cerebral hemorrhage.
Twenty-four patients who had received cranioplasty were selected and divided according to the period from decompressive craniectomy to cranioplasty into early (≤90 days) and late (>90 days) groups. The Korean version of the Mini-Mental State Examination (K-MMSE), Korean version of the Modified Barthel Index (K-MBI), and Functional Independence Measure (FIM) were evaluated at admission just after decompressive craniectomy and during the follow-up period after cranioplasty.
Twelve patients were included in the early group, and another 13 patients were included in the late group. The age, gender, type of lesion, and initial K-MMSE, K-MBI, and FIM did not significantly differ between two groups. However, the total gain scores of the K-MMSE and FIM in the early group (4.50±7.49 and 9.42±15.96, respectively) increased more than those in the late group (−1.08±3.65 and −0.17±17.86, respectively), and some of K-MMSE subscores (orientation and language) and FIM subcategories (self-care and transfer-locomotion) in the early group increased significantly when compared to those in the late group without any serious complications. We also found that the time to perform a cranioplasty was weakly, negatively correlated with the K-MMSE gain score (r=−0.560).
Early cranioplasty might be helpful in restoring cognitive and functional impairments, especially orientation, language ability, self-care ability, and mobility in patients with traumatic brain injury or spontaneous cerebral hemorrhage.

To investigate the effect of laryngopharyngeal neuromuscular electrical stimulation (NMES) on dysphonia in patients with dysphagia caused by stroke or traumatic brain injury (TBI).
Eighteen patients participated in this study. The subjects were divided into NMES (n=12) and conventional swallowing training only (CST, n=6) groups. The NMES group received NMES combined with CST for 2 weeks, followed by CST without NMES for the next 2 weeks. The CST group received only CST for 4 weeks. All of the patients were evaluated before and at 2 and 4 weeks into the study. The outcome measurements included perceptual, acoustic and aerodynamic analyses. The correlation between dysphonia and swallowing function was also investigated.
There were significant differences in the GRBAS (grade, roughness, breathiness, asthenia and strain scale) total score and sound pressure level (SPL) between the two groups over time. The NMES relative to the CST group showed significant improvements in total GRBAS score and SPL at 2 weeks, though no inter-group differences were evident at 4 weeks. The improvement of the total GRBAS scores at 2 weeks was positively correlated with the improved pharyngeal phase scores on the functional dysphagia scale at 2 weeks.
The results demonstrate that laryngopharyngeal NMES in post-stroke or TBI patients with dysphonia can have promising effects on phonation. Therefore, laryngopharyngeal NMES may be considered as an additional treatment option for dysphonia accompanied by dysphagia after stroke or TBI.

To investigate the factors related to upper extremity functional improvement following inhibitory repetitive transcranial magnetic stimulation (rTMS) in stroke patients.
Forty-one stroke patients received low-frequency rTMS over the contralesional hemisphere according to a standard protocol, in addition to conventional physical and occupational therapy. The rTMS-treated patients were divided into two groups according to their responsiveness to rTMS measured by the self-care score of the Korean version of Modified Barthel Index (K-MBI): responded group (n=19) and non-responded group (n=22). Forty-one age-matched stroke patients who had not received rTMS served as controls. Neurological, cognitive and functional assessments were performed before rTMS and 4 weeks after rTMS treatment.
Among the rTMS-treated patients, the responded group was significantly younger than the non-responded group (51.6±10.5 years and 65.5±13.7 years, respectively; p=0.001). Four weeks after rTMS, the National Institutes of Health Stroke Scale, the Brunnstrom recovery stage and upper extremity muscle power scores were significantly more improved in the responded group than in the control group. Besides the self-care score, the mobility score of the K-MBI was also more improved in the responded group than in the non-responded group or controls.
Age is the most obvious factor determining upper extremity functional responsiveness to low-frequency rTMS in stroke patients.

To investigate the association of family history of stroke with functional outcomes in stroke patients in Korea.
A case-control study was conducted. A total of 170 patients who were admitted to a rehabilitation unit were included. Risk factors for stroke such as age, sex, diabetes mellitus, hypertension, atrial fibrillation, smoking, high blood cholesterol and homocysteine level, obesity, and family history of stroke were taken into account. Stroke subtypes were the following: large vessel infarct, small vessel infarct, embolic infarct, subarachnoid hemorrhage, and intracranial hemorrhage. Stroke severity as assessed with the National Institutes of Health Stroke Scale (NIHSS), functional outcomes using the Korean version of the Modified Barthel index (K-MBI), Functional Independence Measurement (FIM), and cognitive function using the Korean version of Mini-Mental State Examination (K-MMSE) were assessed at admission and discharge.
Subjects with a family history of stroke were more likely to have an ischemic stroke (90.7%) than were those without a family history (70.9%). The K-MBI, FIM, NIHSS, and K-MMSE scores did not show significant differences between patients with or without family history.
Family history of stroke was significantly associated with ischemic stroke, but not with functional outcomes. Other prognostic factors of stroke were not distributed differently between patients included in this study with or without a family history of stroke.

To elucidate the association between glycemic control status and clinical outcomes in patients with acute ischemic stroke limited to the deep branch of the middle cerebral artery (MCA).
We evaluated 65 subjects with first-ever ischemic stroke of the deep branches of the MCA, which was confirmed by magnetic resonance angiography. All subjects had blood hemoglobin A1c (HbA1c) measured at admission. They were classified into two groups according to the level of HbA1c (low <7.0% or high ≥7.0%). Neurological impairment and functional status were evaluated using the National Institutes of Health Stroke Scale (NIHSS), Functional Independence Measure (FIM), Korean version of Modified Barthel Index (K-MBI), Korean version of Mini-Mental State Examination (MMSE-K), and the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) at admission and discharge. Body mass index, serum glucose, homocysteine and cholesterol levels were also measured at admission.
The two groups did not show any difference in the NIHSS, FIM, K-MBI, MMSE-K, and LOTCA scores at any time point. Body mass index and levels of blood homocysteine and cholesterol were not different between the two groups. The serum blood glucose level at admission was negatively correlated with all outcome measures.
We found that HbA1c cannot be used for predication of clinical outcome in patients with ischemic stroke of the deep branch of the middle cerebral artery.

Spasmodic dysphonia is defined as a focal laryngeal disorder characterized by dystonic spasms of the vocal cord during speech. We described a case of a 22-year-old male patient who presented complaining of idiopathic difficulty swallowing that suddenly developed 6 months ago. The patient also reported pharyngolaryngeal pain, throat discomfort, dyspnea, and voice change. Because laryngoscopy found no specific problems, an electrodiagnostic study and videofluoroscopic swallowing study (VFSS) were performed to find the cause of dysphagia. The VFSS revealed continuous twitch-like involuntary movement of the laryngeal muscle around the vocal folds. Then, he was diagnosed with spasmodic dysphonia by VFSS, auditory-perceptual voice analysis, and physical examination. So, we report the first case of spasmodic dysphonia accompanied with difficulty swallowing that was confirmed by VFSS.

To assess head posture using cervical spine X-rays to find out whether forward head posture is related to myofascial pain syndrome (MPS) in neck and shoulder.
Eighty-eight participants who were diagnosed with MPS in neck and shoulder were evaluated in this study. Four parameters (distance among head, cervical spines, and shoulder, and cervical angle) were measured from lateral view of cervical spine X-ray. The location and number of trigger points in the neck and shoulder and symptom duration were evaluated for each patient.
Both horizontal distances between C1 vertebral body and C7 spinous process and between the earhole and C7 vertebral body were negatively correlated with cervical angle reflecting cervical lordosis (p<0.05). Younger patients had significantly (p<0.05) less cervical angle with more forward head posture. There was no relationship between MPS (presence, location, and number of trigger points) and radiologic assessments (distance parameters and the cervical angle).
Forward head posture and reduced cervical lordosis were seen more in younger patients with spontaneous neck pain. However, these abnormalities did not correlate with the location or the number of MPS. Further studies are needed to delineate the mechanism of neck pain in patients with forward head posture.

To delineate cervical radiculopathy that is found in combination with traumatic cervical spinal cord injury (SCI) and to determine whether attendant cervical radiculopathy affects the prognosis and functional outcome for SCI patients.
A total of 66 patients diagnosed with traumatic cervical SCI were selected for neurological assessment (using the International Standards for the Neurological Classification of Spinal Cord Injury [ISNCSCI]) and functional evaluation (based on the Korean version Modified Barthel Index [K-MBI] and Functional Independence Measure [FIM]) at admission and upon discharge. All of the subjects received a preliminary electrophysiological assessment, according to which they were divided into two groups as follows: those with cervical radiculopathy (the SCI/Rad group) and those without (the SCI group).
A total of 32 patients with cervical SCI (48.5%) had cervical radiculopathy. The initial ISNCSCI scores for sensory and motor, K-MBI, and total FIM did not significantly differ between the SCI group and the SCI/Rad group. However, at discharge, the ISNCSCI scores for motor, K-MBI, and FIM of the SCI/Rad group showed less improvement (5.44±8.08, 15.19±19.39 and 10.84±11.49, respectively) than those of the SCI group (10.76±9.86, 24.79±19.65 and 17.76±15.84, respectively) (p<0.05). In the SCI/Rad group, the number of involved levels of cervical radiculopathy was negatively correlated with the initial and follow-up motors score by ISNCSCI.
Cervical radiculopathy is not rare in patients with traumatic cervical SCI, and it can impede neurological and functional improvement. Therefore, detection of combined cervical radiculopathy by electrophysiological assessment is essential for accurate prognosis of cervical SCI patients in the rehabilitation unit.

To clarify the relationship of skin temperature changes to clinical, radiologic, and electrophysiological findings in unilateral lumbosacral radiculopathy and to delineate the possible temperature-change mechanisms involved.
One hundred and one patients who had clinical symptoms and for whom there were physical findings suggestive or indicative of unilateral lumbosacral radiculopathy, along with 27 normal controls, were selected for the study, and the thermal-pattern results of digital infrared thermographic imaging (DITI) performed on the back and lower extremities were analyzed. Local temperatures were assessed by comparing the mean temperature differences (ΔT) in 30 regions of interest (ROIs), and abnormal thermal patterns were divided into seven regions. To aid the diagnosis of radiculopathy, magnetic resonance imaging (MRI) and electrophysiological tests were also carried out.
The incidence of disc herniation on MRI was 86%; 43% of patients showed electrophysiological abnormalities. On DITI, 97% of the patients showed abnormal ΔT in at least one of the 30 ROIs, and 79% showed hypothermia on the involved side. Seventy-eight percent of the patients also showed abnormal thermal patterns in at least one of the seven regions. Patients who had motor weakness or lateral-type disc herniation showed some correlations with abnormal DITI findings. However, neither pain severity nor other physical or electrophysiological findings were related to the DITI findings.
Skin temperature change following lumbosacral radiculopathy was related to some clinical and MRI findings, suggesting muscle atrophy. DITI, despite its limitations, might be useful as a complementary tool in the diagnosis of unilateral lumbosacral radiculopathy.

In herpes zoster infection, neurological complications may be overlooked because pain is a more prominent symptom and because peripheral polyneuropathy associated with weakness is rare. A 57-year-old male visited our hospital, complaining of pain and skin eruptions on the right flank. He was diagnosed as having herpes zoster and the symptoms were alleviated by administration of acyclovir for a week. After three weeks, the herpes zoster relapsed. He was re-admitted and diagnosed with chronic myeloid leukemia (CML), and imatinib mesylate was prescribed for five weeks. Ten weeks after the onset of herpes zoster, bilateral foot drops and numbness of the right foot dorsum developed. Through an electrodiagnostic study, he was diagnosed as having peripheral polyneuropathy that was suspected to be caused by neural invasion by varicella zoster virus. After administration of famciclovir, not only the pain but also the neurologic symptoms improved. We herein report a case of peripheral polyneuropathy that was supposed to be related to herpes zoster.

To investigate swallowing laterality in hemiplegic patients with stroke and recovery of dysphagia according to the laterality.
The sample was comprised of 46 dysphagic patients with hemiplegia after their first stroke. The sample's videofluoroscopic swallowing study (VFSS) was reviewed. Swallowing laterality was determined by the anterior-posterior view of VFSS. We measured width difference of barium sulfate liquid flow in the pharyngoesophageal segment. If there was double or more the width of that from the opposite width in the pharyngoesophageal segment more than twice on three trials of swallowing, then it was judged as having laterality. Subjects were assigned to no laterality (NL), laterality that is ipsilateral to hemiplegic side (LI), and laterality that is contralateral to hemiplegic side (LC) groups. We measured the following: prevalence of aspiration, the 8-point penetration-aspiration scale, and the functional dysphagia scale of the subjects at baseline and follow up.
Laterality was observed in 45.7% of all patients. Among them, 52.4% were in the hemiplegic direction. There was no significant difference between groups at baseline in all measurements. When we compared the changes in all measurements on follow-up study, there were no significant differences between groups.
Through this study, we found that there was no significant relation between swallowing laterality and the severity or prognosis of swallowing difficulty. More studies for swallowing laterality on stroke patients will be needed.

Collet-Sicard syndrome is a rare condition characterized by the unilateral paralysis of the 9th through 12th cranial nerves. We describe a case of a 46-year-old man who presented with dysphagia after a falling down injury. Computed tomography demonstrated burst fracture of the atlas. Physical examination revealed decreased gag reflex on the left side, decreased laryngeal elevation, tongue deviation to the left side, and atrophy of the left trapezius muscle. Videofluoroscopic swallowing study (VFSS) revealed frequent aspirations of a massive amount of thick liquid and incomplete opening of the upper esophageal sphincter during the pharyngeal phase. We report a rare case of Collet-Sicard syndrome caused by Jefferson fracture.
