PURPOSE: Transaxillary and periareolar incision in augmentation mammaplasty has risks of injury to branches of intercostal nerves that lead to sensory loss of upper inner arm and nipple. The aim of study was to compare the incidence of sensory loss between two groups according to incision method. METHODS: One hundred seventy one cases that received transaxillary or periareolar subpectoral breast augmentation at the M.D. Clinic from Jan. 2006 to Jul. 2007 were evaluated for sensory loss of upper inner arm and nipple. The cases were divided into transaxillary (118 cases, 69%) and periareolar group (53 cases, 31%). The type of sensory loss was divided into temporary and permanent. The postoperative follow-up periods were from 7 to 22 months (mean: 8.5 months). RESULTS: In cases of upper inner arm, results were as follows; temporary sensory loss in 9 cases (7.6%) and permanent in 2 cases (1.7%) in the transaxillary incision group and, temporary sensory loss in 1 case (1.9%) and no permanent sensory loss in the periareolar incision group. There is no statistical difference between the two groups for permanent sensory loss (P=0.340). In cases of nipples, results were as follows; temporary sensory loss in 26 cases (22%) and permanent sensory loss in 12 cases (10.2%) in the transaxillary incision group, and temporary sensory loss in 12 cases (10.2%) and permanent sensory loss in 3 cases (5.7%) in the periareolar incision group. There was no statistical difference between two groups (P=0.335). CONCLUSION: There was no statistical difference in sensory loss of upper arm and nipple between transaxillary and periareolar approach after subpectoral augmentation mammaplasty.

Magnetic resonance imaging(MRI)has proved to be a valuable method for evaluation of the head and neck. Unfortunately, metallic devices associated with certain dental fillings and applicances often cause variable artifacts that can obscure normal or pathologic conditions on MR and computed tomography. In this work, we assessed the MR appearance of dental prosthetic materials in vitro and in vivo including precious alloys. Nonprecions alloys, resin, amalgam and titanium alloy, For in vivo studies, these materials were placed in healthy volunteer's mouths and then images were assesed. Analyis of the appearance of shape and extent of artifact,and observed influence of these artifacts on the image interpretation at 0.2 Tesla permanent type MR scanner were valuated. Material used as temporary or permanent filling of crowns such as amalgam. precious alloy and, microfilled resin did not cause artifact on the image. The size of the artifact produced by the nonprecious alloys was influenced by the ferromagnetism of the object and the volume prosthesis, and was related to the scanning sequence. Nonprecious alloys produced minimal local signal distortions, where precious alloys, and dental resin had no effect on the MR image in vivo. These results were mainly from a low field strength MR scanner used in this study.

Purpose:
To determine associations of illness symptoms, perception of illness, coping with quality of life (QOL) of thyroid cancer patients and identify factors affecting their QOL.
Methods:
A cross-sectional study was performed using a self-administered questionnaire for 111 thyroid cancer patients after thyroidectomy. They were recruited from the outpatient clinic of one university hospital.Data collection was conducted from August 2018 to November 2018.
Results:
The QOL was significantly associated with interpersonal coping (β= 0.31, p< .001), monthly household income (β= 0.30, p< .001), illness symptoms (β= -0.22, p= .017), perception of illness (β= -0.20, p= .031), and education (β= 0.18, p= .037) in stepwise multiple regression. These factors explained 33.1% of QOL of thyroid cancer patients.
Conclusion
Interpersonal coping is a major contributing factor to QOL. Therefore, thyroid cancer patients need good interpersonal coping for better quality of life.

Perutaneous Transluminal Angioplasty(PTA) is an effective initial treatment modality in renovascularhypertension. For determination of PTA effect, the pulse pressure recording of renal artery is not simple ascompared with in femoral artery stenosis. We tried to evaluate the PTA effect of renal artery stenosis withtracing the pressure of distal renal artery. We used the cardiac catheterization apparatus(VR-12 Honeywell) as apressure monitor in two cases of focal renal arterial stenosis. The renal artery pressure was doubled after firstattempt of ballooning, and the pressure elevated up to 94% and 79% of aorta pressure in two cases, respectively,after third attempt. We believe that renal artery pressure monitoring is a good method of determination of PTAeffect in renovascular hypertension.

Purpose: To evaluate the clinical and radiographic results of primary bipolar arthroplasty during average 9.8-year period, using a non-cemented Multilock femoral stem and a biarticular acetabular cup. Materials and Methods: This study included 24 patients (29 hips) who underwent primary bipolar hemiarthroplasties with Multilock femoral stems and biarticular cups and who could be followed for more than seven years. Clinically, we evaluated the Harris Hip scores and patient complaints of thigh and inguinal pain. We also evaluated the radiographic measurements around the femoral stems and the bipolar cups. Results: The average Harris Hip score improved from 57.4 points to 91.6 points; and 3 (10.3%) hips were associated with thigh pain and 4 (13.8%) hips with inguinal pain. Around the femoral stem there was a non-progressive radiolucent line less than 1 mm in length in 4 (13.8%) hips and osteolysis was present in 6 (20.6%) hips. With respect to the stability of the fixations, there was osseous ingrowth in 26 (89.7%) hips and fibrous ingrowth in 3 (10.3%) hips. Around the acetabulum there was osteolysis in 5 (17.2%) hips, proximal migration of the cup in 2 (6.9%) hips, and erosion of the acetabular cartilage in 10 (34.5%) hips. There were 3 (10.3%) biarticular cups, which were converted to total hip arthroplasties, but no femoral stems were revised. The overall failure rate of the primary operations was 10.3%. Conclusion: The current study demonstrated favorable results after bipolar hemiarthroplasties with Multilock femoral stems. However, the osteolysis that occurred around the femoral stems and the acetabula emerged as a problem after the total hip arthroplasties. In particular, it is expected that the osteolysis would increase over time and become the main cause for the need for surgical revision.

A detailed study of the distribution of neuropeptide Y(NPY) in the olfactory bulb of the male adult and aging rat brains was undertaken by means of immunohistochemistry. Adult rats(Sprague-Dawley, 12-14 weeks old) were used in the control group. And aging rats(30 months old) were used in the experimental group. Brain tissues of both rat groups were obtained from each animal which were perfused transcardially with 0.9% NaCl followed by a 4% paraformaldehyde solution. Coronal serial sections(30nm) were cut on a freezing microtome, and were immunostained with the rabbit-raised antiserum to neuropeptide Y. In the control group, neuropeptide Y-immunoreactive(NPY-IR) neurons were mainly found in the white matter and deep internal granule cell layer, and rarely in the external plexiform layer of main olfactory bulb. In case of accessory olfactory bulb, a few of NPY-IR neurons were found in the internal granule cell layer. Virtually most neurons were medium-sized(10-20nm), and appeared to be bipolar or bitufted in shape. And small numbers of large-sized multipolar neurons(20-30nm) were found in the internal granule cell layer of main olfactory bulb. In the experimental aging rats, the numbers of NPY-IR neurons were decreased, that is to say, NPY-IR neurons in aging group were found average 2.5 neurons per each section compared with average 4.5 per each section in the control group. Also many perikarya of NPY-IR neurons appeared shrinkage, oval or round in shape. In brief, NPY-IR neurons of the olfactory bulb seem to be decreased in number of the neurons in aging rat. These findings may concern with reduction of olfactory function.

PURPOSE: To analyze the effect of treatment of unstable intertrochanteric fractures with dynamic hip screw and additional trochanter stabilizing plate. MATERIALS AND METHODS: Among twenty three cases of unstable intertrochanteric fractures treated with DHS and additional TSP between January 2002 to December 2004, seventeen cases over sixty years old were reviewed with minimal follow up of one year. We analyzed the type of fracture by AO classification, the age of patient, sex, the cause of trauma in seventeen cases. We evaluated the lag screw slippage, the change of neck-shaft angle and lateral displacement of greater trochanter, the period of union by comparison of last follow up radiographs with immediate postoperative radiographs. The fixation failure is defined that displacement of lag screw tip is more than 3 mm or cut out of the screw from the femoral head. RESULTS: The period of union was average 12.8 weeks. The lag screw slippage was average 8.22 mm. The change of neck-shaft angle was average 2.66 degree. No lateralization of greater trochanter was noted in twelve cases, but five cases showed average 0.8 mm (range: 0.5~1 mm) of lateral displacement of greater trochanter. There was not fixation failure. CONCLUSION: In unstable intertrochanteric fracture, the addition of a TSP to the dynamic hip screw can decrease a change of neck shaft angle, a lag screw slippage, and prevent lateral displacement of greater trochanter.

The Journal of the Korean Orthopaedic Association 2006;41(1):96-102
PURPOSE: This study evaluated the minimum ten-year result of primary total hip arthroplasty with a non-cemented Multilock femoral stem. MATERIALS AND METHODS: Fifty five total hip replacements in forty-four patients using a non-cemented Multilock femoral stem and Harris-Galante 2 acetabular component were performed between January 1992 and December 1994. Forty-four hips in thirty-six patients were available for follow up for an average of eleven years (range, ten to twelve years). The clinical results were evaluated based on the Harris hip scores. A detailed radiography analysis was performed by an evaluation of the radiolucent lines, femoral osteolysis, and fixation stability by Engh Method. RESULTS: The average Harris hip score improved from 54.3 points preoperatively to 93.6 points postoperatively. Non-progressive radiolucencies < 2 mm in width were observed in nine (20.5%), and femoral osteolysis was observed in thirteen cases (29.5%). For the fixation stability, osseous ingrowth was noted in thirty nine cases (88.6%) and fibrous ingrowth was observed in two (4.5%). There were three (6.8%) cases with unstable fixation. Two hips underwent revision. The survival rate of the femoral component was 93.2% (forty one cases) after a minimum ten-year follow up. CONCLUSION: The non-cemented Multilock femoral component provided excellent clinical and radiographic results. However, the rate of femoral osteolysis was relatively high (mostly restricted to zone 1 and 7).
