Hand tumorsare many and varied, although benign tumors are common. The pathology and histology of these tumors are not unlike these characteristics of the tumor when it occurs elsewhere. Early diagnosis and proper treatment of all hand tumors have been emphasized since the growth of tumors and pain can cause disturbance of intrinsic function of the hand. For the period of 10 years from 1977 to 1986, 105 cases of hand tumor were treated surgically and the results of clinical observation were as follows ; l. Among 105 cases, benign tumor was 101 cases(96.2%) Bone origin tumor was 20 cases, in which enchondroma and enchondromatosis were 17 cases(70%). Soft tissue origin tumor was 85 cases, in which ganglion was 54 cases(63.5%). 2. Among 105 cases, 42 cases were male and 63 cases were female. In age distribution, it showed even distribution. 3. In the duration of wymptom, 51 cases were below 1 year(48.6%). 4. The tumor occured 85 cases in soft tissue, 14 in phalanx, 7 in metacarpal and 1 in carpal bone. 5. The tumors were treated by excision or curettage and bone graft with good improvement, but postoperatively recurred in 2 cases of Hemangioma. Ampuation was performed in 3 cases of malignant tumors without recurrence.

The most common cause of obstructive sleep apnea syndrome (OSAS) in childhood is adenotonsillar hypertrophy. Adenotonsillectomy improves the symptoms quite well in most cases. However, some patients could experience the OSAS again after adenotonsillectomy, who might have several risk factors such as incomplete operation, misdiagnosis, combined anatomical malformation, sinusitis or chronic allergic rhinitis, obesity, initial severe OSAS, and early onset OSAS. We report a case of 11-year-old obese boy who presented with snoring for several years. He was obese with body mass index (BMI) of 26.3 kg/m2 and also found to have fatty liver by ultrasonogram. Initial polysomnography (PSG) showed that he met the criteria of severe OSAS with the apnea-hypopnea index (AHI) of 70.5. He underwent adenotonsillectomy and symptoms improved immediately. Four months later symptoms were relieved with AHI of 0, but 1 year after the adenotonsillectomy he started to complain snoring again and the subsequent PSG results showed that OSAS has relapsed with AHI of 43. Paranasal sinus X-ray and physical examination showed sinusitis and re-growth of adenoid. Obesity was proved not to be a contributing factor because his BMI decreased to normal range (23.1 kg/m2) after diet control and regular exercise. Also, liver transaminase was normalized and fatty liver was disappeared on follow-up abdominal ultrasonogram. After treatment of sinusitis, symptoms were relieved with decreased AHI (8.5). This case suggests that simple adenotonsillectomy might not be the end of OSAS treatment in childhood. Patients who had adenotonsillectomy should be followed by subsequent PSG if symptoms recur. It is also important to be aware of risk factors in the recurrent OSAS for the proper intervention according to the cause.

PURPOSE: To describe MR findings of recurred giant cell tumor of bone. MATERIALS AND METHODS: MR imagings of ten cases of pathologically proven recurrence of giant cell tumor were retrospectively analyzed. Location of recurrence, multiplicity of recurred tumor, signal intensity and homogeneity, pattern of gadolinium enhancement, soft tissue and articular surface involvement were evaluated. RESULTS: Tumors were located in peripheral portion of previous operation site(80%). Six cases recurred as multiple lesions. Tumor showed low signal intensity on T1 weighted images(100%), high signal intensity on T2 weighted images(100%) and inhomogeneous peripheral rim enhancing pattern(75%). Soft tissue and articular surface involvement were also demonstrated. CONCLUSION: We concluded that characteristic MR findings of recurred giant cell tumor could be helpful in early detection and precise evaluation of tumor recurrence.

STUDY DESIGN: A retrospective study. OBJECTIVES: To analyze restoration of segmental lordosis and factors related to interbody fusion and the fusion rate with degenerative lumbar disease. SUMMARY OF LITERATURE REVIEW: Few studies have addressed the restoration of segmental lordosis and factors related to interbody fusion for degenerative lumbar disease. MATERIALS AND METHODS: Records of 43 patients treated by anterior lumbar interbody fusion (ALIF) or posterior lumbar interbody fusion (PLIF) surgery from 2011 to 2013 were reviewed. ALIF used a metal cage with a 10degrees lordotic angle and PLIF used a metal cage with an 8degrees lordotic angle. Preoperative, postoperative, and at least 1 year outcomes were analyzed from radiographs. As a related factor, segmental flexibility, disc height, osteophytes, vaccuum disc, hypertrophic facet, spondylolisthesis, and endplate violation were analyzed. We also analyzed the bony union rate. RESULTS: The segmental lordotic angle was 4.67degrees before surgery, improved to 10.43degrees after surgery, and was 9.32degrees at the final follow-up. Comparing between the ALIF and PLIF at the L3-4 level in a similar number of patients revealed 7.24degrees and 4.61degrees restoration after ALIF and PLIF surgery, postoperatively. The difference was statistically significant (p=0.011). Segmental flexibility had a statistically significant positive correlation (p=0.013). Lower disc height and osteophytes limited restoration of segmental lordosis, but vaccuum disc was restored well after interbody fusion. Bony union was achieved in 92.8% of the cases. CONCLUSIONS: Intebody fusion, especially ALIF surgery, results in acceptable restoration of segmental lordosis. Even with narrowed disc space or osteophytes, remained segmental flexibility is an important factor of segmental lordosis restoration.

Localized nodular myositis is an uncommon benign inflammatory myopathy of unkonwn cause affecting skeletal muscle and, presenting as a localized painful swelling within the soft tissue of an extremity. Histological examination reveals lymphocytic infiltration, scattered muscle fiber necrosis and regeneration, and interstitial fibrosis. MRI finding is an enhancement with increased signal intensity around the lesion. We report two cases of localized nodular myositis presenting as pseudothrobothrombophlebitis. We believe this is the first case report of localized nodular myositis in Korea.

PURPOSE: To determine whether primary snoring could be distinguished from obstructive sleep apnea syndrome (OSAS) by clinical evaluation and symptom scores. METHODS: 56 snoring and 20 asymptomatic subjects were recruited and polysomnography was used to confirm that there were 39 OSAS, 17 primary snoring, and 20 control subjects. We evaluated the size of the childrens adenoids and tonsils. Parents completed sleep disordered breathing scale (SDBS) and obstructive sleep apnea 18 (OSA-18) questionnaires for use as symptom scores, as well as an attention deficit hyperactivity disorder rating scale-IV (ADHD RS-IV). RESULTS: There were no differences between primary snoring and OSAS in terms of tonsil and adenoid size, SDBS (9.4+/-4.6 vs 10.8+/-4.5), and OSA-18 score (61.1+/-25.1 vs 71.2+/-8.4). The patients with OSAS (15.8+/-7.9) and PS (22.2+/-9.4) had a higher ADHD RS-IV score than the control subjects (2.9+/-3.3). There was no difference in the ADHD RS-IV scores of patients with primary snoring and OSAS. CONCLUSION: We confirmed that clinical evaluation could not distinguish OSAS and primary snoring. In addition, our study suggests that primary snoring as well as OSAS is associated with attention deficit hyperactivity disorder.

Anti-Müllerian hormone (AMH) is now accepted as an important clinical marker of ovarian reserve and is increasingly measured as an initial evaluation at infertility clinics. The aim of this study was to establish reference values for the revised second generation (Gen II) assay using population-based data. In this population-based cohort study, AMH data from unselected infertile women aged 25–45 years from June 2013 to June 2014 (n = 15,801) were collected. The AMH values were measured using the revised Gen II assay. We established and validated 5 AMH-age regression models. Based on the optimal AMH-age model, reference values and centile charts were obtained. The quadratic model (log AMH = 0.410 × age − 0.008 × age²− 3.791) was the most appropriate for describing the age-dependent decrease in AMH measured using the revised Gen II assay. This is the largest population-based study to establish age-specific reference values of AMH using the revised Gen II assay. These reference values may provide more specific information regarding the ovarian reserve estimation of infertile women.

BACKGROUND AND OBJECTIVES: Many patients experience middle ear surgery via retroauricular approach. While not a main interest of the surgery, the change of the auricular shape after surgery has been a subject of complaint by some patients. In this study, we wanted to determine if a change in the auricular shape occurs after middle ear surgery and evaluate the possibility of using reconstruction of posterior auricular muscle as a treatment option for this kind of change. SUBJECTS AND METHOD: Forth patients who received middle ear surgery were enrolled in this study. Retroauricular incision and canal up mastoidectomy were carried out to all patients. The patients were separated into two groups randomly before surgery: one group that had the reconstruction of posterior auricular muscle during surgery, and the other that did not. The average of heights of the helix was compared. Also, patients were asked to fill out a questionnaire about auricular shape before and after surgery. RESULTS: The heights of helix increased about 1.6 mm after surgery; however, the difference of increment as a result of reconstruction of posterior auricular muscle was not statistically significant. Questionnaire about the change of auricular shape after surgery showed that only 8% patients had noticed about the change of auricular shape after surgery. CONCLUSION: Most patients have no complaint about auricular shape after middle ear surgery via retroauricular approach. The average of heights of the helix increases after middle ear surgery. However, the reconstruction of the posterior auricular muscle is not effective for reducing the observed increment of heights of the helix following middle ear surgery via retroauricular approach.

PURPOSE: We assessed the predictive factors for renal insufficiency in patients followed for more than 5 years after radical nephrectomy. MATERIALS AND METHODS: Age, gender, history of diabetes, history of hypertension, body mass index, preoperative estimated glomerular filtration rate (eGFR), serum uric acid, urine albumin, normal renal parenchymal volume, tumor size, and ratio of normal parenchymal volume of the removed kidney to that of the remaining kidney were evaluated retrospectively in 89 patients who underwent radical nephrectomy from January 2001 to December 2005. Patients were included whose renal parenchymal volume was measurable by use of perioperative imaging (computed tomography or magnetic resonance imaging), whose preoperative eGFR was greater than 60 mL/min/1.73 m2, and who were followed for more than 5 years. To measure renal parenchymal volume from imaging, we integrated the extent of the normal renal parenchyma from axial slides of images. RESULTS: In univariate and multivariate binary regression analysis, the parenchymal volume of the remnant kidney (p=0.001), a history of diabetes (p=0.035), and preoperative eGFR (p=0.011) were independent factors for renal insufficiency. By use of a receiver operating characteristic curve, a volume of 170 mL was determined to be an appropriate cutoff value, with sensitivity of 58.7% and specificity of 74.4% for the parenchymal volume of the remnant kidney for predicting eGFR less than 60 mL/min/1.73 m2 (area under the curve, 0.678). The parenchymal volume of the remnant kidney was also an independent factor for the downgrading of the chronic kidney disease category in the multivariate linear regression analysis (p=0.021). CONCLUSIONS: Preoperative eGFR, a history of diabetes, and the radiologic volume of the remaining kidney parenchyma could be useful factors for predicting postoperative renal function. Patients with parenchymal volumes of less than 170 mL have a higher risk of postoperative renal insufficiency, which should be considered carefully when choosing a treatment modality.
