Laryngotracheal Separation for Intractable Aspiration in Severe Brain Damage / 대한연하장애학회지

Laryngotracheal separation (LTS) is one of the treatment options for intractable aspiration. Here, we present two cases of LTS with successful prevention of intractable aspiration.The first case was a 60-year-old man with severe hypoxic brain damage caused by hydrogen sulfide (H2S) intoxication; he was admitted to our department for comprehensive rehabilitation. Frequent tracheal suction was required due to the excess secretion from saliva aspiration. Matters were complicated when he suffered frequent regurgitation and vomiting, which was followed by tracheal aspiration. In the second case, a 78-year-old man presented with a severe traumatic brain injury. He had experienced recurrent aspiration pneumonia, which was unresponsive to conventional therapy. In both cases, LTS was performed to prevent intractable aspiration pneumonia. Subsequent to the LTS procedure, videofluoroscopic swallowing study showed complete prevention of the aspiration in both patients. Moreover, tracheal secretion was reduced, and tracheal suction was no longer required. Post-surgery, there was no development of aspiration pneumonia during their hospital stays.

Efficacy of Portable Low Power Laser Therapy on Pain and Functions in Chronic Low Back Pain

Objective@#A prospective, assessor-blinded, randomized controlled trial was conducted in patients with chronic low back pain to evaluate the efficacy of portable low power laser therapy (LPLT) and the effect when combined with exercise therapy on pain and functions. Method: 60 patients were recruited and 56 patients, excluding 4 dropouts, were randomly allocated to the LPLT group (Group 1: 19 patients), placebo laser therapy with exercise group (Group 2: 18 patients), and LPLT with exercise group (Group 3: 19 patients). Laser therapy and exercise was performed five times a week for 4 weeks. Visual analogue scale (VAS), Schober test, lumbar range of motion (ROM) measures (flexion, extension and lateral flexion), Oswestry Disability index (ODI) were measured at baseline, at 4 weeks after intervention, and at 6 weeks after 2 weeks of no intervention. @*Results@#Statistically significant improvements were noted in all group by time interaction with respect to all outcome parameters (p＜0.05). All parameters in each group improved not only in the period of treatment (4 weeks), but also in the final evaluation (6 weeks) 2 weeks after the end of treatment. Post-hoc analysis showed statistically significant difference between the LPLT with exercise group and the other groups in all outcome parameters except for the ODI at 4 weeks and at 6 weeks. @*Conclusion@#Portable LPLT is effective treatment in reducing pain and improving lumbar ROM and with exercise is more effective than laser or exercise monotherapy for the chronic low back pain patients.

Comparison of Two Static Stretching Techniques for the Triceps Surae in Healthy Individuals: Wall and Inclined Board Stretchings

Objective@#To compare the effectiveness of static stretching techniques for correcting the tightness of the triceps surae. @*Methods@#In this observational, cross-sectional study, participants (30 healthy volunteers) completed 10 repetitions of each stretching exercise, holding each stretch for 10 seconds, with a 1-minute rest period between repetitionsand a 1-hour rest period between the two stretching techniques, namely, wall and inclined board stretchings. The length of the triceps surae and range of ankle dorsiflexion were measured on lateral view radiographs. The muscle activity during the stretch was measured using quantified surface electromyography of the lateral gastrocnemius. The subjective stretching sensation was evaluated using the visual analog scale. @*Results@#Both stretching techniques showed statistical differences in all the parameters. Stretching on an inclined board yielded a greater increase in the triceps surae length than did wall stretching (mean difference, 0.72; p=0.02). The range of ankle dorsiflexion was higher with inclined board stretching than with wall stretching (mean difference, 2.57; p=0.03). The mean muscle activity was significantly lower withinclined board stretching than with wall stretching (mean difference, 53.72; p<0.01). The visual analog scale score was higher with inclined board stretching than with wall stretching (mean difference, 2.07; p<0.01). @*Conclusion@#In this study, inclined board stretching was more effective than wall stretching for correcting tightness of the triceps surae. Therefore, inclined board stretching should be encouraged for the triceps surae.

Swallowed Oro-esophageal Tube: A Case Report / 대한연하장애학회지

Tube feeding is used to provide nutritional support to patients who have difficulty taking food orally. A nasogastric tube is commonly used for these patients but there are some complications. Therefore, the oro-esophageal tube feeding method was developed to avoid these disadvantages. A 33-year-old male with a history of right basal ganglia intracranial hemorrhage was admitted to the rehabilitation department for the treatment of dysphagia caused by a new onset left basal ganglia intracranial hemorrhage. After the videofluoroscopic swallowing study, the nasogastric tube feeding was changed to intermittent feeding via an oro-esophageal tube. Unfortunately, the patient swallowed the tube during insertion. Hence, an emergent endoscopy was performed for tube removal. This article reports a rare case of a patient who underwent oro-esophageal tube removal with an esophagogastroduodenoscopy after tube swallowing during insertion. The insertion of an oro-esophageal tube requires a careful approach after considering the cognitive function, muscle strength, and family education.

Subacute Combined Degeneration Caused by Nitrous Oxide Intoxication: A Report of Two Cases

We report two cases of subacute combined degeneration (SCD) caused by nitrous oxide (N₂O) gas intoxication, which is rarely reported in Korea. Two patients recreationally inhaled N₂O gas daily for several months. They presented with paresthesia of limbs, voiding difficulty, and gait disturbance. The initial vitamin B₁₂ levels were normal or decreased, but homocysteine levels of the two patients were increased. Magnetic resonance imaging of the cervical spine showed T2-weighted hyperintensity in the bilateral dorsal columns of the cervical spinal cord. Electromyography and somatosensory evoked potential tests for both patients suggested posterior column lesion of the spinal cord combined with sensorimotor polyneuropathy. According to these findings, we concluded that the two patients had SCD. The patient’s symptoms partially improved after cessation of N₂O gas inhalation and the receiving of vitamin B₁₂ supplementation therapy. As the incidence of recreational N₂O gas inhalation is increasing in Korea, physicians must be alert to the N₂O induced SCD in patients presenting with progressive myelopathy.

Falsely Elevated Postvoid Residual Urine Volume in Uterine Myoma

Precise measurement of postvoid residual (PVR) urine volume is a key factor in assessing patients with voiding dysfunction, including those with lower urinary tract problems. The safe and noninvasive ultrasound bladder scan is the preferred mode to measure PVR volume. However, this procedure has a false-positive rate up to 9%, in the presence of ovarian cysts, renal cysts, ascites, or uterine myoma with cystic degeneration. Until now, cystic lesions are known to cause false positivity in ultrasound bladder scanner. However, we encountered falsely-elevated PVR in two cases of non-cystic uterine myomas. We present these cases with detailed radiologic images and volume measurement data.

Quantitative Lymphoscintigraphy to Predict the Possibility of Lymphedema Development After Breast Cancer Surgery: Retrospective Clinical Study

OBJECTIVE: To predict the probability of lymphedema development in breast cancer patients in the early post-operation stage, we investigated the ability of quantitative lymphoscintigraphic assessment. METHODS: This retrospective study included 201 patients without lymphedema after unilateral breast cancer surgery. Lymphoscintigraphy was performed between 4 and 8 weeks after surgery to evaluate the lymphatic system in the early postoperative stage. Quantitative lymphoscintigraphy was performed using four methods: ratio of radiopharmaceutical clearance rate of the affected to normal hand; ratio of radioactivity of the affected to normal hand; ratio of radiopharmaceutical uptake rate of the affected to normal axilla (RUA); and ratio of radioactivity of the affected to normal axilla (RRA). During a 1-year follow-up, patients with a circumferential interlimb difference of 2 cm at any measurement location and a 200-mL interlimb volume difference were diagnosed with lymphedema. We investigated the difference in quantitative lymphoscintigraphic assessment between the non-lymphedema and lymphedema groups. RESULTS: Quantitative lymphoscintigraphic assessment revealed that the RUA and RRA were significantly lower in the lymphedema group than in the non-lymphedema group. After adjusting the model for all significant variables (body mass index, N-stage, T-stage, type of surgery, and type of lymph node surgery), RRA was associated with lymphedema (odds ratio=0.14; 95% confidence interval, 0.04–0.46; p=0.001). CONCLUSION: In patients in the early postoperative stage after unilateral breast cancer surgery, quantitative lymphoscintigraphic assessment can be used to predict the probability of developing lymphedema.

The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. Good Practice Point was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” consists of ‘Chapter 1; Introduction of Stroke Rehabilitation’, ‘Chapter 2; Rehabilitation for Stroke Syndrome, ‘Chapter 3; Rehabilitation for Returning to the Society’, and ‘Chapter 4; Advanced Technique for Stroke Rehabilitation’. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” will provide direction and standardization for acute, subacute and chronic stroke rehabilitation in Korea.

Dysphagia in Patients with Dementia / 대한연하장애학회지

Dysphagia is a frequent problem in dementia as Alzheimer's disease. Changes of swallowing function can be started even in the early stages of dementia. Structural and physiologic changes of oral/dental functions in the elderly underlies in persons with dementia. Cognitive based dysphagia is caused by impairment of consciousness and attention, memory, perception, and goal management related with feeding activities. Behavioral and psycholocal symptoms of dementia (BDSD) often results in dysphagia and eating disorders. Dysphagia in dementia should be approached individually. The goals of the program are the maintenance of the optimal nutrition and the prevention of complication such as aspiration pneumonia. Close observation by medical staffs and caregivers is the key to detect early signs of eating disorders in dementia patients. Assessment includes medical history, oral/dental function, swallowing function, and nutritional status. Sensory stimulation methods, adaptive equipment and utensil, diet modification, behavioral and environmental modification are the strategies for managing the problem. Enteral tube feeding is not proven to improve survival of end state dementia patients.

Cognitive Rehabilitation of Dementia

Cognitive rehabilitation refers to the cognition-based approaches that aim to induce people with cognitive impairment to achieve or maintain an optimal level of psychological and social functioning. Many models and definitions of cognitive rehabilitation exist. In this review, cognitive rehabilitation would be briefly reviewed as three categories; cognitive stimulation, cognitive training and cognitive rehabilitation. Cognitive stimulation is a range of group activities and discussions targeting general enhancement of cognitive and social functioning. Cognitive training is guided practice of standardized cognitive task-sets according to the individual levels. Cognitive rehabilitation is an individual approach using rehabilitation strategy for cognitively disabled person. Goal-setting is essential and emphasis is on improving performance in everyday life.

The Association Between Serum Leptin Levels and Post-Stroke Depression: A Retrospective Clinical Study

OBJECTIVE: To investigate the question of whether serum leptin levels might be associated with post-stroke depression. METHODS: We studied 130 patients who experienced a first episode of stroke of more than three months' duration, without any previous history of depression or speech disorders. Data were collected regarding the patient demographics, depressive mood (Diagnostic and Statistical Manual of Mental Disorders 4th edition [DSM-IV] criteria and Beck Depression Inventory) and serum leptin levels measured by an enzyme-linked immunosorbent assay (ELISA). In addition, the Korean version of Modified Barthel Index (K-MBI) and Korean version of Mini-Mental State Examination (K-MMSE) were used to assess the subjects' independence, in regard to the activities of daily living and cognition. A statistical analysis was performed to determine differences the serum leptin levels between patients with depression and those without depression, and to determine the difference in the MBI and K-MMSE scores between the groups separated according to the serum leptin levels. RESULTS: Higher serum leptin levels were observed in patients with depression, compared with those without depression (38.5 ng/mL [range, 25.1-59.2 ng/mL] vs. 8.2 ng/mL [range, 4.9-17.8 ng/mL]; p30 mg/dL), compared to the other two groups. CONCLUSION: High serum leptin levels are associated with depression after stroke, and patients with elevated serum leptin levels were disadvantaged in regard to functional and cognitive outcomes.

Occipital Condyle Fracture With Isolated Unilateral Hypoglossal Nerve Palsy

Occipital condyle fractures (OCFs) with selective involvement of the hypoglossal canal are rare. OCFs usually occur after major trauma and combine multiple fractures. We describe a 38-year-old man who presented with neck pain and a tongue deviation to the right side after a traffic accident. Severe limitations were detected during active and passive range of neck motion in all directions. A physical examination revealed a normal gag reflex and normal mobility of the palate, larynx, and shoulder girdle. He had normal taste and general sensation in his tongue. However, he presented with a tongue deviation to the right side on protrusion. A videofluoroscopic swallowing study revealed piecemeal deglutition due to decreased tongue mobility but no aspiration of food. Plain X-ray film findings were negative, but a computed tomography study with coronal reconstruction demonstrated a right OCF involving the hypoglossal canal. An electrodiagnostic study revealed evidence of right hypoglossal nerve palsy. We report a rare case of isolated hypoglossal nerve palsy caused by an OCF.

Clinical Practice Guideline for Stroke Rehabilitation in Korea 2012

"Clinical Practice Guideline for Stroke Rehabilitation in Korea 2012" is a 2nd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 1st edition published in 2009. After 1st stroke rehabilitation CPG, many studies concerning stroke rehabilitation have been published and the necessity for update has been raised. The Korea Centers for Disease Control and Prevention supported the project "Development of Clinical Practice Guideline for Stroke Rehabilitation" in 2012. Thirty-two specialists in stroke rehabilitation from 18 universities and 3 rehabilitation hospitals and 10 consultants participated in this project. The scope of this CPG included both ischemic and hemorrhagic stroke from the acute to chronic stages. The purpose of this CPG is to provide guidelines for doctors and therapists to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. "Clinical Practice Guideline for Stroke Rehabilitation in Korea 2012" consists of 'Chapter 1; Introduction of Stroke Rehabilitation', 'Chapter 2; Rehabilitation for Stroke Syndrome, 'Chapter 3; Rehabilitation for Return to the Society', and 'Chapter 4; Advanced Technique for Stroke Rehabilitation'. Both the adaptation and de novo development methods were used to develop this 2nd edition of CPG. The appraisal of foreign CPGs was performed using 'Korean appraisal of guidelines for research and evaluation II' (K-AGREE II); moreover, four CPGs from Scotland (2010), Austrailia (2010), USA (2010), Canada (2010) were chosen for adaptation. For de novo development, articles that were published following the latest foreign CPGs were searched from the database system, PubMed, Embase, and Cochrane library. Literatures were assessed in the aspect of subjects, study design, study results' consistency, language and application possibility in the Korean society. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. GPP (Good Practice Point) was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised.

Sciatic Nerve Injury Caused by a Stretching Exercise in a Trained Dancer

Sciatic nerve injury after stretching exercise is uncommon. We report a case of an 18-year-old female trained dancer who developed sciatic neuropathy primarily involving the tibial division after routine stretching exercise. The patient presented with dysesthesia and weakness of the right foot during dorsiflexion and plantarflexion. The mechanism of sciatic nerve injury could be thought as hyperstretching alone, not caused by both hyperstretching and compression. Electrodiagnostic tests and magnetic resonance imaging revealed evidence of the right sciatic neuropathy from the gluteal fold to the distal tibial area, and partial tear of the left hamstring origin and fluid collection between the left hamstring and ischium without left sciatic nerve injury. Recovery of motor weakness was obtained by continuous rehabilitation therapy and some evidence of axonal regeneration was obtained by follow-up electrodiagnostic testing performed at 3, 5, and 12 months after injury.

Treatment of Dysphagia with Pyridostigmine Bromide in a Patient with the Pharyngeal-Cervical-Brachial Variant of Guillain-Barre Syndrome

A 24-year-old male developed bulbar palsy, ophthalmoplegia, ptosis, and shoulder weakness bilaterally 2 weeks after he had experienced an upper respiratory infection. The electrodiagnostic study demonstrated axonal polyradiculoneuropathy. The repetitive nerve stimulation study (RNS) showed no significant decrement of the compound muscle action potentials (CMAPs). The videofluoroscopic swallowing study (VFSS) showed severe impairment of the pharyngeal phase of swallowing. He was diagnosed as having the pharyngeal-cervical-brachial variant of Guillain-Barre syndrome. The patient's dysphagia was not improved for 3 months. A follow up RNS showed a significant decrement of the CMAPs. Pyridostigmine bromide was tried to improve the dysphagia. The patient showed immediate improvement of his dysphagia on the VFSS after the trial with pyridostigmine bromide. Pyridostigmine bromide was given before each meal for 8 days and he showed continuous improvement of his dysphagia. The follow up VFSS after 3 months showed complete recovery of dysphagia.

Amyotrophic Lateral Sclerosis with an Acute Hypertensive Crises

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder involving the systemic motor neurons, but autonomic nervous function is relatively well preserved. A few studies related to autonomic dysfunction have been reported, but autonomic dysfunction is rare in ALS. Moreover, dysautonomia symptoms are not prominent in patients with ALS. We present a 55-year-old male patient with ALS, who had acute severe hypertension and tachycardia crises, as well as sudden falls in his blood pressure. After he was diagnosed with ALS, he suddenly collapsed and was placed under mechanical ventilation. Several hypertensive attacks and dysautonomic signs then occurred. We successfully controlled the dysautonomia using diazepam and doxazocin mesylate, an alpha receptor antagonist.

Quantification of Vestibulospinal Reflex Under the Stress Condition on Both Soleus Muscles / 대한평형의학회지

BACKGROUND AND OBJECTIVES: Vestibulospinal reflex (VSR), which is measured in static state, tends to be compensated prior to vestibule-ocular reflex. Therefore, by establishing method that enables to track and observe quantified VSR, the reliability of experiment is attempted to be increased. MATERIALS AND METHODS: On five SD Rats to measure electromyogram (EMG), electrodes, in the form of stranded cables composed of seven wires, are chronically implanted on both sides of the soleus muscles. Pre and post operative condition of sitting still, standing, and ladder step walking was compared before, and six and twenty four hours after a unilateral labyrinthectomy with quantified muscle activity in maximal voluntary activity. Simultaneously by using multi modality electric potential plus package, the muscle activity between the two legs was tracked and compared. RESULTS: In the sitting still position, the left/right soleus muscle activities were 25.7/26.0 microV before a unilateral labyrinthectomy which was changed after the surgery with the value of 23.1/8.1 microV and 23.4/14.3 microV when six and twenty four hours passed respectively. In the standing position, 92.8/124.0 microV of preoperative value was changed to 89.6/37.3 microV six hours after the unilateral labyrinthectomy, and it was 97.0/54.7 microV 24 hours after. The preoperative value in ladder step walking test was 56.2/86.0 microV, and postoperative ones were 54.9/21.2 microV and 55.7/38.0 microV after six and twenty four hours respectively. CONCLUSION: VSR assessment method by using quantitative EMG well reflects the process of vestibular compensation, and to maintain the tension of extensor muscles, ladder step walking test is shown to be useful.

Tuberculosis Spondylitis T4-6 with Compression Fracture T5: A Case Report

STUDY DESIGN: Case report OBJECTIVES: We report a case of a female patient who had only upper back pain without neurological symptoms and was later diagnosed with spine tuberculosis in combination with a compression fracture. SUMMARY OF LITERATURE REVIEW: Spine tuberculosis is the most common type of musculoskeletal tuberculosis. However, the indolent nature of tuberculous bone and joint disease often leads to delayed diagnosis and severe neurologic complications. MATERIAL AND METHODS: A 37-year-old female with only upper back pain for five months was admitted. She had no signs, symptoms or past histories related to tuberculosis. She had taken conservative management, but symptoms persisted. RESULTS: By doing motor and sensory evoked potential studies, we questioned spinal cord jury. Then, we confirmed spine tuberculosis T5 with T4 compression fracture by thoracic magnetic resonance imaging and pathologic findings. CONCLUSIONS: When a patient presents constant back pain without neurological symptoms, image study and electromyography should be evaluated.
