Purpose: Proprioceptive function has been known to be important to shoulder stability. However, the function in rotator cuff tear patients is rarely investigated. The purpose of current study is to report the proprioceptive function in rotator cuff tear patients and to analyze the proprioceptive function regarding the tear size and the presence of subscapularis tear. Materials and Methods: Between 2011 and 2012, total 76 patients (male 28 and female 48) were recruited and average age was 61.7 years old (range, 38~76). Preoperatively, joint position senses in internal and external rotation were measured for proprioceptive function testing by method of active re-positioning technique. The absolute difference from set point was measured. Proprioceptive function was further analyzed according to tear size of rotator cuff, the presence of subscapularis tear, visual analogue scale of pain, shoulder functional score (American society of elbow and shoulder score), and ranges of motion in shoulder. Results: The absolute difference for external rotation was $4.9^{\circ}{\pm}2.9^{\circ}$, in normal joint and $4.9^{\circ}{\pm}3.0^{\circ}$for involved joint in rotator cuff tear patients. This difference was not significant statistically (p=0.87). The absolute difference for internal rotation was $4.0^{\circ}{\pm}2.7^{\circ}$in normal joint whereas $4.8^{\circ}{\pm}3.7^{\circ}$ for involved joint showing statistically significant difference (p=0.043). There was some trend that the proprioceptive function of internal rotation was more impaired in the bigger tear size group (more than medium tear) compared to the smaller tear size group (partial thickness and small tear, 5.0 vs. 4.0, p=0.061). The impairment of internal rotation proprioception was also accentuated in patients with subscapularis tear (4.8 vs. 4.0, p=0.065). The proprioceptive function of internal rotation was decreased when the pain visual analogue scale was increased (5.2 vs. 4.0 p=0.04), shoulder functional score was decreased (6.1 vs. 4.2, p=0.005), or range of motion in shoulder joint was restricted (5.3 vs. 3.7, p=0.041). Conclusion: The deficit of proprioceptive function was observed in rotator cuff tear patients. Proprioception for internal rotation was impaired in patients with the bigger tear size and subscapularis tear. Pain, shoulder function score, and range of motion were also shown to be related with the deficit in proprioceptive function.

There exist patients complaining speech problem due to dysesthesia or anesthesia following dental surgical procedure accompanied by local anesthesia in clinical setting. However, it is not clear whether sensory problems in orofacial region may have an influence on motor speech abilities. The purpose of this study was to investigate whether transitory sensory impairment of mandibular nerve by local anesthesia may influence on the motor speech abilities and thus to evaluate possibility of distorted motor speech abilities due to dysesthesia of mandibular nerve. The subjects in this study consisted of 7 men and 3 women, whose right inferior alveolar nerve, lingual nerve and long buccal nerve was anesthetized by 1.8 mL lidocaine containing 1:100,000 epinephrine. All the subjects were instructed to self estimate degree of anesthesia on the affected region and speech discomfort with VAS before anesthesia, 30 seconds, 30, 60, 90, 120 and 150 minutes after anesthesia. In order to evaluate speech problems objectively, the words and sentences suggested to be read for testing speech speed, diadochokinetic rate, intonation, tremor and articulation were recorded according to the time and evaluated using a Computerized Speech $Lab^{(R)}$. Articulation was evaluated by a speech language clinician. The results of this study indicated that subjective discomfort of speech and depth of anesthesia was increased with time until 60 minutes after anesthesia and then decreased. Degree of subjective speech discomfort was correlated with depth of anesthesia self estimated by each subject. On the while, there was no significant difference in objective assessment item including speech speed, diadochokinetic rate, intonation and tremor. There was no change in articulation related with anesthesia. Based on the results of this study, it is not thought that sensory impairment of unilateral mandibular nerve deteriorates motor speech abilities in spite of individual's complaint of speech discomfort.

악취현상은 더 이상 대기오염물질에 한 형태가 아니며 또다른 하나의 감각공해라는 개념이 점차 확산되면서 악취에 대한 관심이 점차 고조되고 있다. 그러나 악취현상의 규명이 국내는 물론 국외에서도 충분한 근거를 제공받지 못하는 데에는 첫째, 대기환경 중에 악취물질은 약 40만종 이상이며, 각 물질의 최소감지 농도(threshold:역치) 값 자체가 수ppm∼수ppb 이하 수준이므로 물질농도를 정확히 규명하는 데에는 물질 고유의 특성과 더불어 상당한 수준의 기술과 장비가 요구된다. (중략)

This study aimed to identify the correlation of stress-coping, humor sense, and adaptation to college of nursing students. Three hundred thirty eight subjects completed a structured questionnaire in June 2012. Data were analyzed using SPSS/WIN 21.0 program. The mean scores were as follows; stress-coping 43.33, humor sense 72.18, and adaptation to college 68.02. It meant beyond the intermediate level. Significant differences were found between adaptation to college scores and general characteristics such as gender, academic year, family type, economic status, campus life satisfaction, relation with faculties, grade, and the relationship with the opposite gender. There was significant but weak correlation of stress-coping, humor sense, and adaptation to college. These results suggest that it is necessary to develop individualized education programs considering students' characteristics. Additionally, university adjustment related factors should be studied.

Herpes zoster (HZ) is the secondary manifestation of an earlier infection with the varicella-zoster virus in one or more dermatomes. As reactivation of the virus is linked to an age-related diminished virus-specific and cell-mediated immunity, HZ develops mainly in elderly people. Acute zoster is painful, but does not incur lasting morbidity. Reactivation of the varicella-zoster virus in the trigeminal nerve (Herpes zoster) occur with severe pain and rash in the oro-facial region. The acute pain decreases as the rash begins to heal. Postherpetic neuralgia(PHN), the most frequent complication of herpes zoster, is usually defined as pain in the involved dermatome that is still present 3 month after rash onset. The clinical characteristics of PHN are, eposodic stabbing pain, burning pain and allodynia, with hypoesthesia and/or dysesthesia. $Neurometer^{(R)}$(neuroselective sensory nerve conduction threshold: sNCT, Automated current perception threshold: CPT, neurotron incorporated. Baltimore, Maryland. 21209 U.S.A.) is convenient, rapid and noninvasive, and allows objective assessment of sensory disturbance. This case is about the postherptic neuralgia patient assessed with $Neurometer^{(R)}$. From this case, we reviewed the pathophysiology and the treatment of PHN and recommend the assessment of pain intensity with $Neurometer^{(R)}$ as quantitative and objective method.

The purpose of this study was to present basic data that is needed in comprehension of dysesthesia after mandibular nerve injury and grasp meaning. We analyzed medical records of 59 patients who were diagnosed as dysesthesia after mandibular nerve injury from January 2007 to July 2009. The results are summarized as follows. 1. The most frequent cause was implant surgery (59%) and the most frequent injured branch of mandibular nerve was inferior alveolar nerve(81%). 2. The period passed after nerve injury showed significant interrelationship with level of pain. Visual Analogue Scale(VAS) increased from 4.82 to 6.91 after 6 month. 3. The period passed after nerve injury did not show significant interrelationship with recovery of dysesthesia. But, when conservative treatment was offered at earlier stage, ratio of patients who showed recovery of symptom tended to increase. 4. In computed tomography, level of invasion into inferior alveolar nerve canal did not show significant interrelationship with level of pain and recovery of dysesthesia. Conclusively, in the patients with dysesthesia of mandibular nerve, inferior alveolar nerve injury by dental implant surgery dominated most significant problem. Although level of invasion into inferior alveolar nerve is the most important factor to initiation of dysesthesia, there are other various factors exert more influence on the level of pain or recovery of dysesthesia. Therefore, begining conservative therapy at earlier stage is encouraged. Also, because nerve injuries can occur without direct invasion into nerve canal, so leaving enough safe space from nerve canal is needed for prevention of indirect nerve injury.
