OBJECTIVE: To know the clinical features of overuse injury in performing musicians and to evaluate related factors that may affect the overuse injury and playing related pain. METHODS: Eighty professional musicians and music college students were examined during 1 year. All were examined by a history taking, physical examination, radiologic exam and if needed electromyography. Nonparametric Sperman's correlation were used for the statistic analysis and 5 interval grading system, visual analog scale for pain, and stress, criteria of joint hypermobility were used for various measurements. RESULTS: Fifty four men were studied in 3 music colleges and a professional orchestra. Frequency of symptom was 46.3%. The string players were most frequently affected (65%), whereas the wind instrument players were least frequently affected (11.5%). The most commonly affected site was the hand and wrist (54.2%) followed by the spine. Patients were divided by the severity into 5 groups and among them the grade 1 was most common (29.6%). No significant correlation was seen between the practice hours per week but a significant correlation was noted between the stress and playing related pain. Joint hypermobility plays an important role in music playing which is dependent on the kind of instruments. CONCLUSION: Incidence of the overuse injury in musicians is high in Korea and the prevention and early treatment are essential for the good outcome of overuse syndrome.

BACKGROUND: The efficacy of tumescent liposuction in the treatment of axillary osmidrosis has been widely established. But there have been few studies that have conducted a comparative analysis according to the level of dermal curettage with respect to the efficacy and safety. OBJECTIVE: The aim of this study was to evaluate the clinical efficacy and complications of tumescent liposuction according to the degree of dermal curettage. METHODS: From September 2004 through August 2009, a total of 33 patients with axillary osmidrosis (66 axillae) were included in this study. Twelve patients (24 axillae) were treated by tumescent liposuction with dermal curettage at the level of the mid-dermis (the classical technique group), and the other 21 patients (42 axillae) were treated by tumescent liposuction with dermal curettage at the level of the dermo-subcutis junction (the modified technique group). The preoperative and postoperative disease severity was measured as 0, 1, 2 and 3. The improvement of symptoms was graded by the patient as excellent, good, fair and poor. We also evaluated the postoperative complications, including skin necrosis, scar, hematoma, sensory disturbance and infection. Biopsies of the axillary skin were performed in 7 patients to confirm the level of dermal curettage and the reduction of apocrine glands after treatment. RESULTS: The follow-up ranged from 6 to 60 months. Six months after treatment, 95.8% (23/24) of the axillae in the classical technique group and 95.2% (40/42) of the axillae in the modified technique group had reduced disease severity below 1. Among the 12 patients treated with the classical technique, 11 (91.7%) had excellent to good results, while 95.2% (20/21) of the patients treated with the modified technique had excellent to good results by the patients' own grading. The complications included skin necrosis, scar and hematoma. In the classical technique group and the modified technique group, the incidence of skin necrosis was 12.5% (3/24) and 2.4% (1/42), respectively, the incidence of scar formation was 4.2% (1/24) and 0%, respectively, and the incidence of hematoma was 8.3% (2/24) and 0%, respectively. The postoperative histologic examinations confirmed that the dermal curettage level was at the mid-dermis in the classical technique and at the dermo-subcutis junction in the modified technique. Interestingly, the histologic examination from the classical technique group revealed vacuolar alteration of keratinocytes and partial separation of the dermo-epidermal junction. CONCLUSION: The efficacy of the modified technique is compatible with that of the classical technique, but the modified technique offers fewer complications. So, the modified technique may improve the cosmetic outcome without reducing the treatment efficacy for the patient with axillary osmidrosis.

OBJECTIVE: To assess the jumper's knee for the symptoms and diagnostics by MRI and ultrasonography in basket ball players. METHOD: Twenty knees of 10 basketball players with chronic knee pain were assessed by the history taking, physical examination and diagnosis by magnetic resonance imaging and ultrasonography. Their average age was 17.4 years. Stanish classification is used for grading the symptoms of jumper's knee. RESULTS: Nine proximal patellar tendons were diagnosed as jumper's knees (45%) and 11 distal tendons were diagnosed as jumper's knees (55%). In ultrasonographic findings, average proximal patellar tendon thickness was 4.5 mm+/-1.2 mm, and distal patella tendon thickness was 7.1+/-1.1 mm. Sensitivity was 63% (12/19) and specificity was rated as 100% (21/21). By the MRI findings, sensitivity was rated as 32% (6/19) and specificity was rated as 90% (16/21). Study between the patient's clinical severity level by Stanish classification and thickness of patellar tendon showed no significant correlation (<0.5). CONCLUSION: The ultrasonography to be more convenient and easier as a diagnostic method for the jumper's knee than MRI.

PURPOSE: To evaluate effectiveness of oblique approach under biplane fluoroscopic guidance in transthoracic fine needle aspiration biopsy. MATERIALS AND METHODS: Fourteen consecutive patients underwent transthoracic fine needle aspiration biopsy for subcarinal lesions. Subcarina was the only accessible biopsy site in 13 patients. Subcarinal biopsy was performed to determine the presence of metastasis in an enlarged subcarinal lymph node in the remaining one patient. Before biopsy, we evaluated the size and location of the lesion on preliminary plain chest X-ray film and CT scan. Under dual projection fluoroscopic guidence, biopsy was performed through right posterior intercostal space with the patient prone by using oblique approach. On 15 degree LAO projection the needle was directed to the area anterior to the spine and advanced to the line extending through the posterior wall of the main bronchus. RESULTS: Cytologic diagnosis was made in 12 out of 14 patients(accuracy 85.7%). The final diagnosis consisted of 5 squamous cell carcinoma, 5 small cell carcinoma, 1 adenocarcinoma and 1 adenosquamous carcinoma. Pneumothorax developed in 2 patients(14%) and was managed by chest tube drainage. Mild hemoptysis was observed in 2. CONCLUSION: Transthoracic fine needle aspiration biopsy using oblique approach under biplane fluoroscopic guidance is a relatively safe and sensitive method for the histologic diagnosis of subcarinal lesion.

BACKGROUND: This study investigated the efficacy and safety of combined subacromial and intravenous patient-controlled analgesia for control of postoperative pain after arthroscopic rotator cuff repair. METHODS: Between May 2012 and August 2014, 60 patients who underwent arthroscopic rotator cuff repair with acromioplasty and received patient-controlled analgesia were studied prospectively. Cases were divided into 2 groups: combined subacromial and intravenous infusion group (group A, 30 cases) and solitary intravenous infusion group (group B, 30 cases). The visual analogue scale was used to record the patient's level of pain every 12 hours during postoperative 72 hours and the following 48 hours after the suspension of patient-controlled analgesia. RESULTS: The mean preoperative visual analogue scale score was 7.8 in group A and 7.6 in group B, and the immediate postoperative visual analogue scale score was 7.9 and 8.1 for each group. At postoperative time (From 12 hours to 72 hours after operation), the scores of combined subacromial and intravenous infusion were significantly lower than those of solitary intravenous infusion. Significant difference in the frequency of supplemental analgesic injections was observed between group A and group B (p=0.008). However, no significant difference in complication rate was observed between the two groups (p=0.562). CONCLUSIONS: Combined subacromial and intravenous patient-controlled analgesia after arthroscopic rotator cuff repair is more effective than solitary intravenous infusion without significantly increasing complications. Therefore, combined subacromial and intravenous patient-controlled analgesia could be a effective pain control method.

BACKGROUND: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. METHODS: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%–75%, Group C: 25%–50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. RESULTS: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). CONCLUSIONS: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

Epidermolytic keratosis palmaris is a rare disease which shows clinical findings of Unna Thost keratoderma and histopathologic of epidermolytic hyperkeratosis. We report herein a case of epidermolytic keratosis palmaris et plantaris in a 16-month-old female baby. Light microscopy shows marked hyperkeratosis, large irregular keratohyalin granules, and large clear spaces in the granular and upper spinous layers. Eletron microscopic findings shows that the clear spaces are areas of cytoplasm filled with a fibrillar material and cellular organelles. Abnormal clumping of tonofilament and keratohyalin is also present.

Urinary cytology has become an essential element in the diagnosis and management of transitional cell carcinoma(TCC) of the urinary tract. It has the advantage of being noninvasive, inexpensive, and easily accessible. Besides that it can even detect malignancy when unsuspected at cystoscopy. We report a retrospective review of urine cytology in the diagnosis of 83 TCC cases that underwent 295 cytologic evaluation. All patients had biopsy-proven TCC of the bladder, ureter and renal pelvis. The overall inci- dence of the positive cytology cases was 66.2%. To define the cytologic features of tumor cells, we tried to use three cytologic gradings such as "grade 1", "grade 2", and "grade 3" according to the cytologic degree of anaplastic neoplastic cells. These cytologic gades of TCC were relatively well correlated with the histologic grade and tumor invasiveness. This result suggests that the recognition of characteristic cellular features of TCC can suspect the histologic grade and tumor stage. The false negative TCC cases were 78.9%. They showed severe inflammatory or bloody background and a few neoplastic cells. Therefore, a cautious approach for accurate interpretation, personal experience, and proper fixation and processing could expand the role of urinary cytology.
