Muscle and Tendon Injury in Thigh

Most muscle and tendon injuries in thigh occur in sports activities with high energy, for example kicking and running, related with deceleration phase, which require eccentric contraction of quadriceps and hamstring. Most common injury is hamstring strain injury (HSI) and also common injuries of anterior thigh is quadriceps strain injury. Strain injuries occur at myo-tendinous junction and surrounding muscle fibers and in most strains except complete rupture first choice of treatment is conservative treatment including RICE in acute phase and subsequent rehabilitation programs. In competitive sports activities such as football quadriceps contusion injury is common after heavy collision. Prognosis is dependent on the extension of muscle fiber damage and hematoma formation. Hematoma formation can develop to myositis ossificans or Morel-Lavellee lesion, which can induce pain and disability. Hamstring and quadriceps strain and tendon tear can occur in middle-aged or elderly people in community circumstances after slip down or falling, which lead to sudden lengthening and eccentric contraction of hamstring or quadriceps.Tendon tear including avulsion tear in greater tuberosity has higher proportion than strain, that is opposite in sports injuries, because middle aged or elderly people have higher possibility of tendon degeneration and tendinosis with higher risk of tendon tear. Therefore rapid and accurate diagnosis and proper treatment including rehabilitation program for hamstring and quadriceps injury is necessary in middle aged or elderly people.

The Association Between Personality Traits and Decision Making in Young Male Adults With Depression / 생물치료정신의학

Objectives@#This study was conducted to investigate the relationship between personality and decision making in the group of young male depression patients. @*Methods@#Eighty-four male depression patients were subjected to the following test: Beck’s Depression Inventory-II (BDI-II), and Beck’s Anxiety Inventory (BAI), Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV), Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Personality Assessment Inventory (PAI), Temperament Character Inventory-Revised Short version (TCI-RS), Delay Discounting Task (DDT), Game of Dice Task (GDT). Pearson’s correlation analysis was used to determine the association between DDT and GDT performance results and self-report examination. Multiple linear regression models were conducted to figure out the causal relationship between risky choice of GDT and the variables suspected of having a linear relationship. The collected data was analyzed using SPSS 21. @*Results@#PAI mania, borderline features, dominance and novelty seeking of TCI-RS were positively correlated with the number of risky choices of GDT. Full Scale Intelligence Quotient, BDI-II, BAI score had no significant correlation with DDT and GDT. There was also no correlation between DDT and GDT. @*Conclusions@#The results suggest that risk taking decision is related to personality traits such as novelty seeking, while inter-temporal choice is not related to personality aspects. It could be inferred that two different decision-making processes take place independently at different brain regions.

The Influence of Pharyngeal Strength on the Outcome of Botulinum Toxin Treatment for Difficulty in Relaxation of the Upper Esophageal Sphincter / 대한연하장애학회지

Objective@#Botulinum toxin was used to treat patients with difficulty in relaxation of the upper esophageal sphincter (UES), but the treatment did not always yield good results. We, therefore, attempted to investigate if there was any other factor affecting the outcome and hypothesized that this could be caused due to pharyngeal constriction. @*Methods@#We conducted a retrospective study on a botulinum toxin injection treatment given to eleven patients with nasal backflow and pharyngeal stasis in the course of a videofluoroscopic swallowing study from August 2006 to December 2012. After the injection, the cases showing an esophageal passage of diluted barium regardless of aspiration were defined as “good”, and the cases showing no passage were defined as “bad”. Pharyngeal strength was measured using the pharyngeal constriction ratio (PCR), which was compared between the two groups using the Mann-Whitney U test for proving the hypothesis. @*Results@#Five of the eleven patients showed esophageal passage after the injection treatment and were assigned to the “good” group. The remaining 6 were assigned to the “bad” group. When comparing the average PCR of each group, the ‘good’ group’s ratio was at 0.09±0.03 and the ‘bad’ group was at 0.29±0.16, showing a statistically significant difference (P＜0.05). @*Conclusion@#The strength of pharyngeal constriction could be considered to be an important factor influencing the outcome after botulinum toxin treatment for the difficulty in relaxation of the UES.

Relationship between Anconeus Epitrochlearis and Ulnar Motor Nerve Conduction Velocity

Objective@#To determine the incidence of anconeus epitrochlearis (AE) muscle and evaluate the correlation between AE muscle and ulnar motor nerve conduction velocity (NCV). Method: Forty healthy volunteers (80 arms) were evaluated. Ulnar motor nerve conduction study was performed. NCVs at the forearm and across the elbow were calculated. Ultrasonography (US) was used to obtain a transverse scan view of the cubital tunnel and confirm the presence of the AE muscle. Cross-sectional areas (CSAs) of following structures were obtained: ulnar nerve (UNCSA), cubital tunnel (CTCSA), and AE (AECSA). AECSA was divided by CTCSA to obtain the AE/CT ratio. Pearson correlation coefficient (PCC) was calculated to evaluate the relationship between NCV across elbow and each variable obtained by US. @*Results@#Sixty-three (78.75%) of eighty arms showed the presence of AE muscle. NCV had no significant correlations with sonographic variables. However, when 17 arms with a relatively low NCV value (≤ 60 m/s) were analyzed, NCV showed significant correlations with AECSA (PCC: r = −0.674, p=0.003) and AE/CT ratio (PCC: r = −0.516, p=0.034). @*Conclusion@#When all 63 cases with AE muscle were analyzed, ulnar NCV showed no significant correlations with sonographic variables. However, when those with NCV value of 60 m/s or less were analyzed, NCV showed significant negative correlations with AECSA and AE/CT ratio.

The Association Between Cancer and Neurodegenerative Diseases: A Retrospective Cohort Study Using the National Health Insurance Service-National Health Information Database / 신경정신의학

Objectives@#According to previous studies, cancer risk has decreased among patients with neurodegenerative disease (ND). However, some types of cancer are positively associated with ND.ND and cancer share common mechanisms of genetic and molecular abnormalities. The objective of this study was to evaluate the association between cancer and ND by comparing the incidence of cancer in the ND and control groups. @*Methods@#A population-based 10-year follow-up study was conducted using the Korean National Health Information Database for 2002–2015. The participants were 60-year-old or more, and they were divided into two groups, including ND (n=9324) and control (n=46683) groups. A multivariable Cox proportional hazards regression model was used to evaluate the hazard ratio and 95% confidence interval for determining cancer risk. @*Results@#About one-third of patients in both groups were diagnosed with ND before the occurrence of cancer during the 10-year follow-up. Cancer was developed in a significantly higher percentage of patients with ND (22.0%) than in the control group (18.4%). Compared to the control group, patients with ND had about 1.5-times higher risk of developing cancer. In the ND group, the incidence of cancer was increased when another ND was diagnosed during the 10-year follow-up. @*Conclusion@#Our results showed a positive association between ND and cancer. Thus, further replication study is needed to address the positive association between NDs and cancer, and it is also necessary to study the association between NDs and various types of cancer.

Impact of Neurodegenerative Disease on the Development of Cancer in Elderly Koreans:A 10-Year Cohort Study Using National Health Insurance Database

Objective@#We evaluated the association between cancer and various neurodegenerative diseases (NDs), including Alzheimer’s disease (AD), Parkinson’s disease (PD), and circumscribed brain atrophy (CBA) and to evaluate the impact of ND on the development of cancer. @*Methods@#A population-based longitudinal study was conducted using the National Health Information Database for 2002-2015.A total of 9,365 ND patients (3,157 AD, 5,866 PD, 342 CBA) were included in the study, as were 46,818 matched controls. @*Results@#Various NDs were newly developed in control and ND groups during the 10-year follow-up periods. Newly developed ND cases were as follows: 33.0% in control, 35.3% in AD, 19.9% in PD, and 45.3% in CBA. Cancer developed in 22.6% of ND groups (20.5% AD, 23.6% PD, 24.3% CBA) and in 18.5% of control group. Cancer development was significantly higher in AD pa-tients with new ND cases (especially PD cases), compared to patients without new ND cases (22.8% vs. 19.3%, p=0.019). There were no differences in the frequencies of cancer development between patients with and without new ND cases in PD, CBA, and control groups. The adjusted hazard ratios for cancer in AD, PD, and CBA groups were 1.43, 1.55, and 1.58, respectively. @*Conclusion@#This study showed that various NDs are positively associated with development of cancer and suggests that newly developed PD in AD group during the follow-up period may influence the development of cancer that follows.

The Effect of Adult ADHD Tendency on Cognitive Functions in Young Male Adults with Depression / 생물치료정신의학

Objectives@#：The purpose of this study was to investigate the effect of adult Attention-Deficit/Hyperactivity Disorder (ADHD) tendency on cognitive functions in the group of depression. @*Methods@#：117 male patients with depression (51 with adult ADHD and 66 with adult non-ADHD) were recruited in this study. All patients were subject to the following tests : Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV), Executive Intelligence Test, Rey-Kim memory test, Beck’s Depression Inventory II (BDI-II), and Beck’s Anxiety Inventory (BAI), Adult ADHD Self-Report Scale (ASRS), Lee Ji-Yeon’s adult ADHD scale. @*Results@#：Compared to the adult non-ADHD group, the adult ADHD group showed lower score in Rey-Kim memory test. Several test scores were negatively correlated with ASRS (free recall test trial 2 : r=-0.184, p=0.047, trial 3 : r=-0.277, p=0.002, trial 4 : r=-0.242, p=0.009, trial 5 : r=-0.264, p=0.004, delayed recall test : r=-0.187, p=0.044, recognition test : r=-0.209, p=0.024). No significant correlation was found between depression, anxiety and Rey-Kim memory test even though there is a meaningful correlation between adult ADHD tendency the severity of depression and anxiety. @*Conclusion@#：In this study, we found the adult ADHD with depression group has difficulties in retaining information and maintaining attention. Interestingly, it was proved the difference comes from ADHD tendency, not from the severity of depression or anxiety.

Association Between Latency of Dermatomal Sensory-Evoked Potentials and Quantitative Radiologic Findings of Narrowing in Lumbar Spinal Stenosis

Objective@#To identify the difference of quantitative radiologic stenosis between a normal latency group and an abnormal latency group, and to investigate the association of dermatomal somatosensory-evoked potential (DSEP) with magnetic resonance imaging (MRI) findings of narrowing in patients with lumbar spinal stenosis (LSS). @*Methods@#We retrospectively reviewed the clinical records and P40 latencies of L5 DSEP of 40 patients with unilateral symptoms of LSS at the L4–5 disc level. Quantitative assessments of stenosis in lumbar spine MRI were performed with measurements of the anteroposterior diameter (APD), cross-sectional area (CSA) of the dural sac, ligamentous interfacet distance (LID), CSA of the neural foramen (CSA-NF), and subarticular zone width. Analyses were conducted through comparisons of radiologic severity between the normal and abnormal latency groups and correlation between radiologic severity of stenosis and latency of DSEP in absolute (APD <10 mm) and relative (APD <13 mm) stenosis. @*Results@#The radiologic severities of lumbar stenosis were not significantly different between the normal and abnormal latency groups. In absolute and relative stenosis, latency showed a significant negative correlation with APD (r=-0.539, r=-0.426) and LID (r=-0.459, r=-0.494). In patients with relative stenosis, a weak significant positive correlation was found between latency and CSA-NF (r=0.371, p=0.048). LID was the only significant factor for latency (β=-0.930, p=0.011). @*Conclusion@#The normal and abnormal DSEP groups showed no significant differences inradiologic severity. The latency of DSEP had a negative correlation with the severity of central stenosis, and LID was an influencing factor.

Comparison of Aided and Unaided Thresholds and Selection Processes of Contralateral Routing of Signal Hearing Aids and Implantable Bone Conduction Devices in Patients with Asymmetric Hearing Loss / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES@#We reviewed the selection processes of contralateral routing of signal (CROS) hearing aids (HAs) and bone-conduction (BC) Has, and compared aided and unaided hearing thresholds.SUBJECTS AND METHOD: Twenty-four patients with asymmetrical hearing loss who used BC HAs (n=12) and CROS HAs (n=12) were enrolled. The choice of two different HAs were compared with respect to the degree of hearing loss, the unaided hearing thresholds and functional gains.@*RESULTS@#When the hearing thresholds of the better hearing ears were >30 dB HL, most (92%, 11 of 12) chose CROS rather than BC HAs, with significant difference (p=0.001). Both CROS and BC HAs groups showed significantly improved functional gains (46.6 dB and 53.4 dB, respectively). Aided air-conduction (AC) thresholds (40.2 dB HL) in the CROS group were similar to the AC thresholds (43.1 dB HL) of better hearing ears. However, the hearing threshold of Aided AC thresholds (35.8 dB HL) in BC HAs group were less than the BC thresholds (17.3 dB HL) of better hearing ears by 19 dB (p30 dB HL. The CROS group showed aided thresholds similar to the thresholds of better hearing ears, but the BC HAs group showed poorer aided thresholds than the thresholds of better hearing ears. For patients with asymmetric hearing loss, HAs should be selected based on the degree and types of hearing loss and the maximum output level of the selected device.

Posterior Epidural Migration of a Lumbar Intervertebral Disc Fragment Resembling a Spinal Tumor: A Case Report

Posterior epidural migration of a lumbar intervertebral disc fragment (PEMLIF) is uncommon because of anatomical barriers. It is difficult to diagnose PEMLIF definitively because of its relatively rare incidence and the ambiguity of radiological findings resembling spinal tumors. This case report describes a 76-year-old man with sudden-onset weakness and pain in both legs. Electromyography revealed bilateral lumbosacral polyradiculopathy with a mass-like lesion in L2-3 dorsal epidural space on lumbosacral magnetic resonance imaging (MRI). The lesion showed peripheral rim enhancement on T1-weighted MRI with gadolinium administration. The patient underwent decompressive L2-3 central laminectomy, to remove the mass-like lesion. The excised lesion was confirmed as an intervertebral disc. The possibility of PEMLIF should be considered when rim enhancement is observed in the epidural space on MRI scans and electrodiagnostic features of polyradiculopathy with sudden symptoms of cauda equina syndrome.

Laparoscopic Excision of Anterior Abdominal Wall Tumors: A Case of Desmoid-Type Fibromatosis Arising in the Rectus Muscle

PURPOSE: Laparoscopic approaches to the anterior abdominal wall are difficult because of the inherent limitations of laparoscopic surgery. METHODS: A 25-year-old young female visited to our hospital with an incidentally-found palpable abdominal mass. Computed tomography revealed a 7-cm round enhancing mass arising from the left posterior rectus sheath. The patient underwent laparoscopic excision of the inner mass arising from the anterior abdominal wall. RESULTS: The operation lasted for 45 minutes and there was no measurable bleeding during the procedure. Pathological assessment revealed that the tumor was a DTF 7.0 cm in size. The patient was discharged on the second postoperative day in good condition, and is currently being followed on a routine basis for surveillance without adjuvant therapy. CONCLUSION: Laparoscopic approach for the anterior abdominal wall tumor could be feasible in select patients. This minimally-invasive approach helps to ensure good cosmetic outcomes and quality of life.

Factors Affecting Emotional Status and Suicidal Risk in Hospitalized Medical Patients / 정신신체의학

OBJECTIVES: This study aimed to identify the group with high risk of suicide in general hospital inpatient by comparing the depression, anxiety, and distress and their clinical characteristics. METHODS: The study included all patients admitted to a general hospital between January 2016 and December 2017, and the final 41,249 patients were analyzed. Distress thermometer (DT) and hospital anxiety-depression scale (HADS) were used for emotional state evaluation. Group with high risk of suicide was defined as showing more than 4 in the DT and more than 8 in one of the two subscales (anxiety and depression) of the HADS. RESULTS: Among the subjects, 3,603 patients (8.7%) met the high-risk criteria for suicide. The group with high risk of suicide experienced more severe pain than the control patient group, and it was found that there was more underlying disease. Patients who reported pain showed higher scores than those who reported no pain on the DT and HADS subscales. CONCLUSIONS: Group with high risk of suicide showed more severe pain and more underlying disease. Therefore, suicide prevention program specifically targeted for the group with high risk of suicide should be developed according to the risk of the patient evaluated at the time of the admission.

Effect of Drug-Induced Sedation Endoscopy on the Decision of Treatment Plan in Patients with Obstructive Sleep Apnea / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Drug-induced sedation endoscopy (DISE) has recently gained popularity among otolaryngologists because it can provide direct information of upper airway obstruction in patients with obstructive sleep apnea (OSA). In that regard, we examined how DISE examination affected the decision of clinician's treatment plan and the consequent patient's compliance in OSA patients. SUBJECTS AND METHOD: All enrolled patients were classified into two groups according to the method of upper airway evaluation employed: a physical examination only group and a physical examination combined with DISE group. The clinician's treatment plan was categorized into the following four groups: sleep surgery, positive airway pressure, oral appliance, and sleep surgery combined with oral appliance. The change of patient's compliance was also evaluated. RESULTS: There were several differences in how DISE evaluation affected the decision of clinician's treatment plan and patient's compliance between the two groups. The rate for sleep surgery fell from 69.6% to 15.9%; on the other hand, the rate for positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 13.0% to 36.2%, 14.5% to 26.6%, and 2.9% to 21.3%, respectively. The patient's compliance also changed after DISE evaluation: sleep surgery, positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 78.1% to 87.9%, 16.7% to 76.0%, 25.0% to 87.3%, and 50.0% to 91.03%, respectively. CONCLUSION: We found that DISE examination influences the decision of clinician's treatment plan and patient's compliance. We suggest additional cohort studies to confirm these findings.

Essential Clinical Tips about Ultrasound Guided Cervical Intervention

This report suggests indications, detailed procedures, clinical efficacy and safety of ultrasound (US) guided cervical interventions, such as selective nerve root block (SNRB), medical branch block (MBB), facet joint intra-articular (FJIA) injection, third occipital nerve (TON) block and greater occipital nerve (GON) block. Comparing with fluoroscopy guided transforaminal and interlaminar epidural blocks, US guided cervical interventions have similar clinical effects and superior safety. For cervical axial pain and cervicogenic headache US guided MBB or FJIA injection can be performed. Usual targets of injection are upper cervical (C2–3) for cervicogenic headache and lower cervical (C5–6) for axial neck pain. Clinical effect of US guided MBB is reported to be similar to fluoroscopy guided MBB. Instead of upper cervical (C2–3) facet joint injection, TON block is usually performed. The accuracy of US guided TON block and MBB is reported as high with confirmation of fluoroscopy. GON block can be performed for occipital neuralgia, migraine, chronic daily headache, etc. US guided GON block is much safe and supposed to be highly accurate compared with blind technique. Ultrasonography guided cervical interventions are effective to reduce pain and most of all safe procedure. We need to use ultrasonography guided intervention actively in the field of clinic.

Analysis of Long-Term Complication on Patients with Obstructive Sleep Apnea Who Treated Mandibular Advancement Device / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Recently, mandibular advancement device (MAD) has been used widely used for the treatment of obstructive sleep apnea (OSA) because it can effectively reduce the collapsibility of upper airway during sleep. Although MAD is widely prescribed by otorhinolaryngologists, several studies described its complications arising from the anterior placement of the mandible with long-term use. However, there is still a lack of studies on long-term complications in Korean patients. SUBJECTS AND METHOD: Retrospectively, we included a total of 57 OSA patients in the study. In this study, all enrolled OSA patients had used MAD over two years with more than 4 hours/day. Dental consulting and cephalometric analysis were conducted to identify the change of dental and skeletal findings at two different times (baseline and after 2 year). RESULTS: The dental findings showed that the overbite and overjet were significantly decreased. Additionally, the proclination of the lower incisors were increased significantly, whereas there was no significant change on the retroclination of the upper incisors. Three patients showed a change of malocclusion type. On the analysis of skeletal findings, we found a significant increase in the sella turcica central point-nasion-supramental point angle and a decrease in the subspinal point-nasion-supramental point angle. Moreover, the anterior lower facial height and anterior facial height were significant increased. CONCLUSION: Consistent with Western studies, our findings suggest that the long-term use of MAD could induce changes in dental and skeletal morphologies in Korean OSA patients. Therefore, clinicians should thoroughly evaluate potential changes in dental and skeletal morphologies when they prescribe MAD to patients with OSA.

Diagnosis of Churg-Strauss Syndrome Presented With Neuroendocrine Carcinoma: A Case Report

Churg-Strauss syndrome (CSS) is a rare systemic vasculitis that affect small and medium-sized blood vessels and is accompanied by asthma, eosinophilia, and peripheral neuropathy. This report describes a case of a 52-year-old man who had a history of sinusitis, asthma, and thymus cancer and who had complained of bilateral lower extremity paresthesia and weakness for a month. Peripheral neuropathy was detected by electrodiagnostic studies. Resection of a mediastinal mass, which was diagnosed as thymic neuroendocrine carcinoma, was performed five months before his visit. After thymectomy, peripheral blood tests revealed a gradual increase in eosinophils. Two months after surgery, he was admitted to the hospital for dyspnea, and nodules of focal consolidation were found in his chest X-ray. One month later, pyoderma occurred in the right shin, and the skin biopsy showed extravascular eosinophilic infiltration. He was diagnosed with CSS after thymectomy, and we report a very rare case of CSS presented with thymic neuroendocrine carcinoma.

Efficacy of Intensive Neurodevelopmental Treatment for Children With Developmental Delay, With or Without Cerebral Palsy

OBJECTIVE: To evaluate the effectiveness of intensive neurodevelopmental treatment (NDT) on gross motor function for the children having developmental delay (DD), with or without cerebral palsy (CP). METHODS: Forty-two children had intensive NDT three times weekly, 60 minutes a day, for 3 months, immediately followed by conventional NDT once or twice a week, 30 minutes a day, for another 3 months. We assessed Gross Motor Function Measure (GMFM) over three time points: before conventional NDT, before and after intensive NDT, and after 3 months of additional conventional NDT. RESULTS: The GMFM score in DD children significantly improved after intensive NDT, and the improvement maintained after 3 months of conventional NDT (p<0.05). The children were further divided into two groups: DD with CP and DD without CP. Both groups showed significant improvement and maintained the improvements, after intensive NDT (p<0.05). Also, there was no significant difference in treatment efficacy between the two groups. When we calculate the absence rate for comparing the compliance between intensive and conventional NDT, the absence rate was lower during the intensive NDT. CONCLUSION: Intensive NDT showed significantly improved gross motor function and higher compliance than conventional NDT. Additionally, all improvements were maintained through subsequent short-term conventional NDT. Thus, we recommend the intensive NDT program by day-hospital centers for children with DD, irrespective of accompanying CP.

Increased Bolus Volume Effect on Delayed Pharyngeal Swallowing Response in Post-stroke Oropharyngeal Dysphagia: A Pilot Study

OBJECTIVE: To confirm a relationship between the pharyngeal response and bolus volume, and examine whether increasing the fluid bolus volume can improve penetration and aspiration for stroke dysphagic patients. METHODS: Ten stroke patients with a delayed pharyngeal response problem confirmed by a videofluoroscopic swallowing study (VFSS) were enrolled. Each subject completed two swallows each of 2 mL, 5 mL, and 10 mL of barium liquid thinned with water. The pharyngeal delay time (PDT) and penetration-aspiration scale (PAS) were measured and the changes among the different volumes were analyzed. RESULTS: PDTs were shortened significantly when 5 mL and 10 mL of thin barium were swallowed compared to 2 mL. However, there was no significant difference in PAS as the bolus volume increased. CONCLUSION: The increased fluid bolus volume reduced the pharyngeal delay time, but did not affect the penetration and aspiration status.
