BACKGROUND: Superior migration of humeral head has been conventionally determined by measuring the acromiohumeral distance (AHD), We sought to devise a novel measurement system more reliably and accurately than AHD. We described a structural landmark called 'C-line'. In this study, we investigated the clinical usefulness of 'step-off of the C-line (SOC)' compared to that of AHD. METHODS: The C-line formed from the medial margin of the proximal humeral head continuing up to the inferior margin of the articular glenoid and then to the lateral border of the scapula. The superior migration of the humeral head triggered by a rotator cuff tear introduces a discontinuity in this C-line. We measured the distance of this discontinuity. We enrolled 144 patients who underwent a rotator cuff repair. We selected 58 controls who didn't have any cuff lesions apparent on magnetic resonance imaging. Using radiographs derived from standardized true anteroposterior views of the shoulder, we measured the SOC and the AHD. We used t-tests for statistical analyses. RESULTS: A rotator cuff tear was associated with an increase in SOC and a decrease in AHD. In control group, the mean SOC was 1.29 ± 1.71 mm and AHD was 9.71 ± 2.65 mm. In cuff tear group, the mean SOC was 3.15 ± 3.41 mm and AHD was 8.28 ± 1.76 mm. The mean SOCs of the patient group in relation to the mean SOC of the control group according to tear size, the SOCs of medium tear and lager groups showed statistically significant increase (p<0.05). CONCLUSIONS: The SOC may be a similarly effective to diagnose cuff tears of medium size and larger compared with AHD.

OBJECTIVE: This study is proposed to examine the relationship between bone loss after hormone replacement therapy for one year and initial bone markers. METHODS: One hundred postmenopausal women were studied for one year. At first visit, measurements were made of bone mineral density(BMD) at the lumbar spine and femoral neck, and of serum osteocalcin and urine deoxypyridinoline. After hormone replacement therapy was done for one year, BMD was rechecked. RESULTS: Serum osteocalcin was correlated with the rate of bone change(r=0.150, 0.262) and urine deoxypyridinoline was weakly correlated(r=-0.003, 0.038). The changes of femoral BMD in women with higher concentration of osteocalcin and deoxypyridinoline were significant different from those in women with normal concentration. At the lumbar spine, no significant differences were showed. In women with higher concentration of osteocalcin, the incidence of subjects with increased spine BMD was increased up to around 71.1%, which showed not significant increase compared with normal concentration of osteocalcin. And the incidence of increased spine BMD in women with higher concentration of osteocalcin was marked increased compared with the incidence of normal concentration. The level of the osteocalcin with increased spine BMD was 11.5+/-6.6 ng/ml, and the level with decreased spine BMD was 9.2+/-4.7 ng/ml, respectively. And the level of the deoxypyridinoline was 7.2+/-4.2 pmol/ mol cr in women with increased spine BMD and 7.2+/-2.7 pmol/ mol cr in women with decreased spine BMD, which was not statistically different. The concentration of deoxypyridinoline with increased and decreased in BMD in spine and femur was not statistically different. but the concentration of osteocalcin was 12.2 +/-5.5 ng/ml in significantly increased in BMD and 8.5 +/-4.5ng/ml in significantly decreased in BMD, which was showed significant different. CONCLUSION: Present study indicates that the serum osteocalcin more reflcets bone turnover changes at the menopause than deoxypyridinoline, however, the clinical utility of measurements of osteocalcin only to response to therapy is uncertain.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.

In general, pelvic fracture carries higher mortality especially from motor veicle accident, we have retrospectively reviewed charts and radiographs of 185 patients in order to identify clinical fading, kinds of fracture, hemodynamic changes and associated injuries in patients with pelvic fractures. We attempted to classify pelvic fractures according Young classification. The following results were obtained; 1. On age and sex distribution, the pelvic fractures showed peak incidence between 2nd decade and 5th decade. Male was affected more frequently than female, the ratio being male to female, 2.6 to 1. 2. The mechamisn of injury was motor veicle accident in 155(83.8%), fall in 25(13.5%), others in 5(2.7%). 3. The associated injuries of pelvic fractures: extremity, thoracic, urinary system, intraperitoneal and head injury. 4. Of the 185 cases of the pelvic fractures, simple pelvic fractures are 101 cases(54.6%), lateral compression in 39(21.1%), anteroposterior compression in 18(9.7%), vertical shearing in 17(9.2%), mixed pattern in 10(5.4%). 5. Retroperitoneal hematoma and urinary tracts injuries were the most common associated in mixed pattern. 6. The incidence of hemodynamically unstable fractures were 19.8% in simple pelvic fracture but, as expected was higher in major pelvic ring disruptions except to acetabular fracture(52.4%). 7. Mortality rates were 5.9% in all pelvic fractures but 10.7% in major pelvic ring disruptions except to acetabular fractures. Prognostic factor in pelvic fractures were the amount of hemorrhage and associated injuries, therefore early diagnosis and managements are essential to reduce the mortality in pelvic fracture.

Nevus lipomatosus cutaneous superficialis is a very rare skin disease, which usually is present at birth. The lesion shows groups of asymptomatic soft papules or nodules, which have a smooth or folded surface and are skin colored or yellowish. The area of predilection is the pelvic girdle (especially the buttock and sacrococcygeal areas). Microscopically, nevus lipomatosus cutaneous superficialis reveals groups of etopic fat cell nests within the dermis. Only one case was reported in Korea(1969). The authors observed a case of typical nevus lipomatosus cutaneous superficialis. The patient was 19 year-old male, who ha,ve had asymptomatic soft papules and nodules on the buttock, lower back and scalp since 14 years of his age. Routine laboratory findings were within normal limit. Histopathological findings showed etopic fat cell nests within mid and lower dermis (Fig. 3) Diagnosis was confirmed by clinical and histopathological findings. Litercature was briefly reviewed for the discussion.
