Osteoporosis has been described as the most common disease in the old age group. As the bone mineral density decreases, the skeleton becomes more prone to fracture. Hip fractures occur late in life following substantial reduction in skeletal mass. So the incidence of hip fracture is increasing due to prolongation of average life span. The bone density of femoral neck, Ward triangle, and trochanteric region were measured by dual energy x-ray absorptiometry (DEXA) in 15 patients with femoral neck fractures and in 58 patients with intertrochanteric fractures to evaluate the relationship between bone mineral density (BMD) value and fracture type. The results were as follows 1. In femoral neck fracture group, the mean BMD value was 0.59+/-0.02 g/cm2 in femoral neck, 0.38+/-0.08 g/cm2 in Ward triangle and 0.48+/-0.09 g/cm2 in trochanteric region. In intertrochanteric fracture group, the mean BMD value was 0.57+/-0.09 g/cm2 in femoral neck, 0.39+/-0.10 g/cm2 in Ward triangle, and 0.47+/-0.13 g/cm2 in trochanteric region. 2. In femoral neck fracture group, the fracture threshold value was 0.75 g/cm 2 in femoral neck, 0.60 g/cm2 in Ward triangle and 0.67 g/cm2 in trochanteric region. In intertrochanteric fracture group, the fracture threshold value was 0.63 g/cm2 in femoral neck, 0.51 g/cm2 in Ward triangle, and 0.57 g/cm2 in trochanteric region. In conclusion, there was no statistical relationship in BMD value between neck fracture and intertrochanter fracture group, and no statistical relationship between BMD value and each fracture type in femoral neck and intertrochanter fracture. The type of hip fracture may be related to the degree of trauma rather than the value of the BMD.

The incidence of thyroid cancer is rapidly increasing worldwide. Recently, attention to quality of life (QOL) issues has been increasingly addressed in the management of cancer. The goal of this review is provide a systematic overview for clinical factors associated with QOL in patients with thyroid cancer. Age is often cited as a QOL predictor with older patients more vulnerable than younger patients. High levels of fatigue and psychological distress such as anxiety and depression might be associated with decreased QOL. Although surgery for thyroid cancer leads to worse QOL shortly, there is a trend towards recovery with time. Levothyroxine treatment in thyroid cancer can result in similar or slightly impaired QOL. Thyroid hormone withdrawal causes significant reductions of QOL of thyroid cancer patients. The use of recombinant human thyrotropin (rhTSH) instead of thyroid hormone withdrawal can prevent QOL deterioration by thyroid hormone withdrawal. Generally, thyroid cancer survivors have a similar or slightly worse QOL compared with the normative population. In conclusion, thyroid cancer has a considerable impact on QOL of patients, and therefore multidisciplinary approach with special concern for QOL is recommended.

PURPOSE: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. MATERIALS AND METHODS: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. RESULTS: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. CONCLUSION: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

BACKGROUND: Some of the deficiencies in anterior pituitary function identified in subjects with macroadenomas appear to represent irrevemible necrosis of normal pituitary cells, and in addition reversible damage to viable glandular tissue and/or incomplete interruption of local circulation by compression of pituitary stalk may also contribute significantly to hypopituitarism. So anterior pituitary function may actually improve in some patients undergoing successful tumor resection or reduction in tumor size. Although direct comparisons of pituitary function among the various pituitary tumors are not presently available it was reported that there is some difference in the degree of pituitary impairment between patients with nonfunctioning macroadenoma(NFMA) and those with GH-secreting macroadenoma(GHMA).In this study, to investigate the difference in the degree of hypopituitarism we compared anterior pituitary function in subjects with NFMA to that in patients with GHMA. METHODS: In this retrospective study, preoperative and postoperative anterior pituitary function was assessed by clinical findings, basal hormone levels and/or combined pituitary stimulation test in 29 subjects with NFMA and in 24 subjects with GHMA. RESULTS: 1. There was no difference in age, sex, tumor size distribution between the two groups. 2. Preoperatively, NFMA patients had a higher prevalence of secondary hypothyroidism(34% vs. 5%; p(0.02) compared to subjects with GHMA. Patients with NFMA also had a higher prevalence of more severe pituitary failure compared with acromegalic patients; 48% of the patients in this group had more than one pituitary hormone axis impaired compared to 17% in the acromegalic group(p0.03). 3. Postoperatively, NFMA patients also had a higher prevalence of secondary hypoadrenalism (52% vs. 11%; p 0.01) compared with acromegalic patients. Additionally, the prevalence who had more than one pituitary hormone axis impaired was still greater in NFMA patients than in the acromegalic group(57% vs. 22%; p=0.054). 4. No correlation was found between the severity of pituitary failure and tumor size or extension in both groups before and after surgery. CONCLUSION: These findings suggest that anterior pituitary function is relatively better preserved in patients with GHMA than those with NFMA and that this difference is independent of tumor size and extension. The mechanism underlying the lower rate of hypopituitarism in acromegalics with macroadenoma remains to be elucidated.

BACKGROUND AND OBJECTIVES: As septal surgery is being performed more and more often, the incidence of septal perforation as a complication arising from the surgery has also increased. In septal surgery, if corresponding mucoperichondrial tears occurred on both sides, autologous cartilage is usually placed between the injured mucopercondrium. However, septal perforation is sometimes found after septal surgery even after this effort. The aims of this study were to introduce a new technique for the prevention of septal perforation during septal surgery using inferior turbinate mucosa and fibrin glue and to determine its usefullness by evaluating the treatment outcome. MATERIALS AND METHODS: Between June 2005 and May 2007, 358 cases of septal surgery were performed. Bilateral mucoperichondrial tears on corresponding areas occurred in 26 cases. In Group 1 (15 cases), autologous cartilage was inserted between injured mucoperichondrium. In Group 2 (11 cases), autologous cartilage was inserted and then was repaired using fibrin glue and inferior turbinate mucosa. The authors compared the perforation rate between the two groups. RESULTS: In Group 1, septal perforation occurred in 7 of 15 patients (46.7%) and in Group 2, 1 of 11 patients (9.0%) had perforation. Perforation rates were significantly lower in Group 2. CONCLUSION: The technique of using fibrin glue and inferior turbinate mucosa may be an easy, effective method for the prevention of septal perforation during septal surgery.

The aim of this study was to compare serum nitrotyrosine concentrations in healthy dogs with those in dogs with myxomatous mitral valve disease (MMVD). Fifty client-owned dogs were included in this study. Based on echocardiographic results, dogs were categorized into healthy (control), mild-, moderate-, and severe-MMVD groups. Serum nitrotyrosine concentrations were determined from enzyme-linked immunosorbent assays. No significant difference between control dogs and dogs with mild MMVD was detected (p = 0.31). However, dogs with moderate MMVD had significantly higher serum concentrations of nitrotyrosine (p = 0.04) than that in controls, and dogs with severe MMVD had significantly lower serum concentrations of nitrotyrosine (p = 0.03) than that in moderate MMVD dogs. There were negative correlations in the association of serum nitrotyrosine with age (n = 30, R²= 0.067, p = 0.27), left atrial-to-aortic root diameter ratio (n = 30, R²= 0.02, p = 0.57), and platelet count (n = 30, R²= 0.39, p = 0.003); however, only the platelet correlation was significant. Among dogs with MMVD, there was no significant difference in serum nitrotyrosine concentration between males and females. The results of this study suggest that tyrosine nitration end-products might be potential biomarkers for the detection of MMVD in dogs.

PURPOSE: To evaluate the role of the MRI after the stereotactic radiofrequency ventralis intermedius nucleus (VIM) thalamotomy for the treatment of tremor. MATERIALS AND METHODS: 156 cases of the postthalamotomy MR findings were analized retrospectively. The sagittal T1 weighted image(WI), axial and coronal Proton and T2WI were obtained by using 0.38 T(Resonex Sunnyvale, U. S. A) machine. The interval between thalamotomy and MR examination was from 3 days to 2 months. The MR characteristics and complications related to thalamotomy were reviewed. In 16 cases, a follow-up MR was done 3 to 13 months after the initial MR study. We also reviewed the follow-up MR findings. RESULTS: The mean size of the thalamus lesion was 16 mm. The thalamus lesions were noted as a single layer in 23 cases and as layers of different signal intensity in 100 cases;(2 layers in 84 cases, and 3 or more layers in 16 cases). In 74 cases of the 84 cases with 2 layers, the inner layer was isointense with gray matter on T1WI, hypointense on T2WI, and the outer layer was hypointense on T1WI, hyperintense on T2WI. There were extrathalamic lesions that were related to mistargetting of stereotactic radiofrequency. The locations of the extrathalamic lesions were the posterior limb of the internal capsule(119 cases), the posterior limb of the internal capsule and the midbrain(39 cases), the posterior limb of the internal capsule and the basal ganglia(11 cases), and the midbrain(9 cases). In 5 cases of the mistargetting, double radiofrequency lesions were visualized because of the repeated coagulation. The other complications were intracerebral hemorrhage(2 cases), subdural hemorrhage(2 cases), epidural hemorrhage(1 case), and intraventricular hemorrhage(1 case). On the follow up MR studies(16 cases), 2 cases showed the hemosiderin deposition in periphery of the lesion. CONCLUSION: The MRI was useful for the evaluation of the thalamic lesions and complications after the stereotactic radiofrequency VIM-thalamotomy for the treatment of tremor.

PURPOSE: We evaluated the effect of local recurrence (LR) and regional recurrence (RR) on distant metastasis and survival in patients treated with breast conservation therapy (BCT). METHODS: We analyzed 907 patients who were treated for invasive breast cancer between 1993 and 2006. With 53 months of follow-up, 28 patients (3.1%) developed LR in the breast and 12 patients (1.3%) developed RR before distant metastasis. LR and RR were separated into four patterns to determine the prognostic relevance of recurrence site and time to recurrence: LR within 3 years (early LR), LR after 3 years (late LR), RR within 3 years (early RR), and RR after 3 years (late RR). RESULTS: Early LR (hazard ratio [HR], 4.76; p=0.003) and early RR (HR, 18.16; p<0.001) were independent predictors of distant metastasis. In terms of overall survival, early LR (HR, 5.24; p=0.002), and early RR (HR, 18.80; p<0.001) were significantly related with poor survival. Patients with late LR/RR had a similar favorable prognosis compared with patients who never experienced LR/RR. CONCLUSION: The result suggests that time to LR/RR following BCT is a significant predictor developing a distant metastasis and surviving.
