The endocrinologic complications such as adrenal insufficiency and hypopituitarism are common after traumatic brain injury (TBI) portending poor rehabilitation outcome. Anterior pituitary dysfunction presents as hypothyroidism, hypogonadism, growth hormone deficiency, adrenal insufficiency and hyperprolactinemia, whereas posterior pituitary dysfunction includes syndrome of inappropriate antidiuretic hormone and central diabetes insipidus. Careful history taking and physical examination are essential to detect these abnormalities early. Laboratory tests such as serum/urine sodium and osmolality, thyroid hormone, testosterone, estradiol, cortisol, prolactin, growth hormone or IGF-1 are also necessary. Screening of endocrinologic functions is recommended especially in patients with moderate or severe TBI, skull base fracture or diffuse axonal injury 3 to 6 months after injury. Further studies are needed to reveal the effect of early correction of endocrinologic abnormality on long-term functional outcome.

Tumors are rare causes of calf pain and usually present insidiously. A 69-year-old woman developed sudden severe pain and a hard palpable mass in her left calf that persisted for 6 months without a history of trauma. Although a myofascial trigger point was initially suspected, subsequent ultrasonography revealed two well-defined heterogeneous masses in the calf muscle. Magnetic resonance imaging revealed a multi-lobulated mass involving the soleus, tibialis posterior muscle, and deep peroneal neurovascular bundle, suggesting a soft tissue sarcoma. Fluorine-18-fluorodeoxyglucose positron emission tomography revealed a heterogeneous hypermetabolic lesion in the left calf, suggesting malignancy. The patient received an incisional biopsy of her left calf lesion and was diagnosed with leiomyosarcoma. The patient underwent a wide excision with partial fibulectomy of the left calf and received chemotherapy for metastasis in the left upper lobe of the lung. Although rare, soft tissue sarcoma should be considered in the differential diagnosis if calf pain and a palpable mass persist despite conservative management, and imaging studies are essential for distinguishing tumors from other causes of calf pain.

OBJECTIVE: To investigate the effects of short-term robot-assisted upper limb training on hemiplegic patients compared to conventional physical therapy. METHOD: This study was a prospective, single-blinded, randomized controlled trial. Eighteen hemiplegic patients due to brain lesions were randomly assigned to: (1) robot-assisted upper limb training and conventional upper limb physical therapy for 30 min a day, respectively (Robot group); or (2) conventional upper limb physical therapy for 30 min twice a day (Conventional group). All interventions were provided for 2 weeks, 5 times a week. Each patient was evaluated at pre- and post-treatment by the Fugl-Meyer assessment-upper extremity (FMA-UE), Jebsen hand function test (JHFT), grip power, modified Barthel index-upper extremity (MBI-UE), line bisection test, and Albert test. RESULTS: The Robot group showed significant improvement in FMA-UE (pre: 13.22 +/- 14.20, post: 21.67 +/- 15.84; p = 0.018), MBI-UE (pre: 14.33 +/- 7.42, post: 16.56 +/- 6.95; p = 0.041), and line bisection test (pre: 25.15 +/- 34.48, post: 14.93 +/- 28.38; p = 0.043). The Conventional group showed significant improvement only in MBI-UE (pre: 9.22 +/- 6.06, post: 15.56 +/- 6.19; p = 0.008). The improvement in MBI-UE was larger in the Conventional group than Robot group (6.33 +/- 3.28 vs. 2.22 +/- 2.49; p = 0.014). CONCLUSION: This study suggests that short-term robot-assisted upper limb training may improve upper limb function in hemiplegic patients. However, proper physical therapy may be needed to transfer improved upper limb function to activity of daily living. In addition, goal-directed reaching tasks using a robot are expected to be a treatment option for hemineglect.

OBJECTIVE: To investigate the effect of repetitive magnetic stimulation (rMS) of the spinal cord on limb angiogenesis in healthy rats and explore its implication for the treatment of lymphedema. METHOD: Twelve adult male Sprague-Dawley rats were divided into four groups as follows: sham rMS followed by tissue harvest 5 minutes later (group 1, n=2), 1 Hz rMS and tissue harvest 5 minutes later (group 2, n=3), 20 Hz rMS and tissue harvest 5 minutes later (group 3, n=3), 20 Hz rMS and tissue harvest 30 minutes later (group 4, n=4). Animals were treated with 20-minute rMS with 120% of the motor threshold on their left side of upper lumbar spinal cord. Expression of angiogenic factors, that is, Akt, phospho-Akt (pAkt), endothelial nitric oxide synthase (eNOS), phospho-eNOS (p-eNOS) were measured by western blot. Bilateral hindlimb muscles (quadriceps and gastrocnemius) were harvested. RESULTS: Expression of Akt in left quadriceps increased in group 4 compared with group 2 and 3 (3.4 and 5.3-fold each, p=0.026). Expression of eNOS in left plus right quadriceps markedly increased in group 3 and 4 compared with group 1 and 2 (p=0.007). Expressions of eNOS, Akt and p-eNOS, pAkt in gastrocnemius were not comparable between four groups (p>0.05). CONCLUSION: Repetitive magnetic stimulation of the spinal cord may exert an angiogenic effect closely linked to lymphangiogenesis. It has clinical implication for the possible therapy of lymphedema caused by breast, cervical or endometrial cancer operation. Future studies with the specific lymphatic endothelial cell markers are required to confirm the effect of rMS on lymphangiogenesis.

OBJECTIVE: To investigate the effects of body mass composition and cushion type on seat-interface pressure in spinal cord injured (SCI) patients and healthy subjects. METHODS: Twenty SCI patients and control subjects were included and their body mass composition measured. Seat-interface pressure was measured with participants in an upright sitting posture on a wheelchair with three kinds of seat cushion and without a seat cushion. We also measured the pressure with each participant in three kinds of sitting postures on each air-filled cushion. We used repeated measure ANOVA, the Mann-Whitney test, and Spearman correlation coefficient for statistical analysis. RESULTS: The total skeletal muscle mass and body water in the lower extremities were significantly higher in the control group, whilst body fat was significantly higher in the SCI group. However, the seat-interface pressure and body mass composition were not significantly correlated in both groups. Each of the three types of seat cushion resulted in significant reduction in the seat-interface pressure. The SCI group had significantly higher seatinterface pressure than the control group regardless of cushion type or sitting posture. The three kinds of sitting posture did not result in a significant reduction of seat-interface pressure. CONCLUSION: We confirmed that the body mass composition does not have a direct effect on seat-interface pressure. However, a reduction of skeletal muscle mass and body water can influence the occurrence of pressure ulcers. Furthermore, in order to minimize seat-interface pressure, it is necessary to apply a method fitted to each individual rather than a uniform method.

Dysphagia is caused by various pathologic conditions of which brain disorders are the major etiology. If food materials enter an airway, aspiration pneumonia or serious asphyxia can develop, which necessitates early detection and proper management of dysphagia. Diagnosis of dysphagia includes history taking, physical examination, bedside screening tests, videofluoroscopic swallowing study (VFSS), and fiberoptic endoscopic examination of swallowing (FEES). Dysphagia management or rehabilitation consists of direct and indirect training methods. The direct one consists of modification of the texture and viscosity (using fluid thickener) of the diet, and diverse compensatory techniques for posture change (chin tuck, head rotation, and head tilt), airway protection (supraglottic swallowing and super-supraglottic swallowing) and improvement of bolus passage (effortful swallowing, multiple swallowing, Mendelsohn maneuver). Indirect training methods without using food are made up of thermal tactile stimulation, electrical stimulation of suprahyoid or infrahyoid muscles, repetitive transcranial magnetic stimulation, and strengthening of the tongue or pharyngeal muscles involved in swallowing (Shaker's exercise and vocal cord adduction exercise). Oral hygiene, adequate hydration, and nutritional support are also crucial. Although the prognosis of dysphagia is favorable with proper rehabilitation, enteral feeding through percutaneous endoscopic gastrostomy or an oroesophageal tube would be helpful to patients who have unresolved dysphagia for some time. Further large-scale clinical studies will be needed to establish evidence on various training methods for dysphagia management.

OBJECTIVE: To investigate the therapeutic effects of repetitive electrical stimulation of the suprahyoid muscles in brain-injured patients with dysphagia. METHOD: Twenty-eight brain-injured patients who showed reduced laryngeal elevation and supraglottic penetration or subglottic aspiration during a videofluoroscopic swallowing study (VFSS) were selected. The patients received either conventional dysphagia management (CDM) or CDM with repetitive electrical stimulation of the suprahyoid muscles (ESSM) for 4 weeks. The videofluoroscopic dysphagia scale (VDS) using the VFSS and American Speech-Language-Hearing Association National Outcome Measurement System (ASHA NOMS) swallowing scale (ASHA level) was used to determine swallowing function before and after treatment. RESULTS: VDS scores decreased from 29.8 to 17.9 in the ESSM group, and from 29.2 to 16.6 in the CDM group. However, there was no significant difference between the groups (p=0.796). Six patients (85.7%) in the ESSM group and 14 patients (66.7%) in the CDM group showed improvement according to the ASHA level with no significant difference between the ESSM and CDM groups (p=0.633). CONCLUSION: Although repetitive neuromuscular electrical stimulation of the suprahyoid muscles did not further improve the swallowing function of dysphagia patients with reduced laryngeal elevation, more patients in the ESSM group showed improvement in the ASHA level than those in the CDM group. Further studies with concurrent controls and a larger sample group are required to fully establish the effects of repetitive neuromuscular electrical stimulation of the suprahyoid muscles in dysphagia patients.

Methods: We developed a questionnaire related to VFSS protocols and test diet. It was sent to the expert physicians who directly implementing VFSS in 35 training hospitals, which were sent out and collected by e-mail from December 7, 2017 to February 19, 2018. Among them, 12 out of 28 hospitals selected randomly and we conducted field survey including observing the process of the VFSS. Results: The most common protocol was to provide a test sample with 7 stages (28.1%). In the order of provided test samples, ‘the small amount of liquid’ was the most provided in the 1st stage (53.1%). Among the used samples of thin liquid level, the mixing ratio of the liquid samples and barium was not uniform among each institution. ‘Yogurt (semi-solid type)’ was the most commonly used sample for ‘nectar thick’ and ‘honey thick’ diet. Various samples were used on ‘pudding thick’ diet. Conclusion These results indicate that, in the 32 Korean general hospitals, each hospital uses samples depending on experience or according to its own standards rather than unified standard among the institutions. Thus, the protocols for each hospital are not standardized, which make them difficult to the accurate sharing of information about the test results. Therefore, it will be necessary to make a consensus for the protocol and establish nationwide standard of VFSS through future research

The Harris line (HL), caused by bone-growth arrest and manifesting on X-rays as a radiopaque transverse line in the metaphysis of the long bones, is an indicator reflecting stress conditions such as disease or malnutrition. HL frequency has been assumed to differ between pre-modern and modern societies, as reflective of increased caloric intake and overall nutritional improvements attendant on industrialization. To determine if such a change occurred in Korea, in the present study we compared the respective HL statuses in medieval Joseon and modern Korean population samples. HLs were found in 39.4% (28/71) of the Joseon Koreans. Whereas only 27.5% (11/40) of the males showed an HL, fully 54.8% (17/31) of the females exhibited it. Notably, HLs were observed in only 16.4% (35/213) of the modern Koreans; more remarkably still, the HL rate was almost the same between the sexes, 16.7% (20/120) for the males and 16.1% (15/93) for the females. The HL frequency was much higher in the Joseon Koreans than in their modern counterparts, reflecting the improvement of nutritional status that had been achieved in the course of South Korea's modernization. This HL-frequency decrease was much more obvious in the female populations. The higher HL frequency among the Joseon females might reflect the relatively poor nutritional condition of females in pre-modern Korean society.

OBJECTIVE: To compare the treatment effects of epidural neuroplasty (NP) and transforaminal epidural steroid injection (TFESI) for the radiating pain caused by herniated lumbar disc. METHODS: Thirty-two patients diagnosed with herniated lumbar disc through magnetic resonance imaging or computed tomography were included in this study. Fourteen patients received an epidural NP and eighteen patients had a TFESI. The visual analogue scale (VAS) and functional rating index (FRI) were measured before the treatment, and at 2 weeks, 4 weeks and 8 weeks after the treatment. RESULTS: In the epidural NP group, the mean values of the VAS before the treatment, and at 2 weeks, 4 weeks and 8 weeks after the treatment were 7.00+/-1.52, 4.29+/-1.20, 2.64+/-0.93, 1.43+/-0.51 and those of FRI were 23.57+/-3.84, 16.50+/-3.48, 11.43+/-2.44, 7.00+/-2.15. In the TFESI group, the mean values of the VAS before the treatment, and at 2 weeks, 4 weeks and 8 weeks after the treatment were 7.22+/-2.05, 4.28+/-1.67, 2.56+/-1.04, 1.33+/-0.49 and those of FRI were 22.00+/-6.64, 16.22+/-5.07, 11.56+/-4.18, 8.06+/-1.89. During the follow-up period, the values of VAS and FRI within each group were significantly reduced (p<0.05) after the treatment. But there were no significant differences between the two groups statistically. CONCLUSION: Epidural NP and TFESI are equally effective treatments for the reduction of radiating pain and for improvement of function in patients with a herniated lumbar disc. We recommend that TFESI should be primarily applied to patients who need interventional spine treatment, because it is easier and more cost-effective than epidural NP.
