BACKGROUND: Many hyaluronic acid (HA)-based anti-adhesive agents have been commercialized for clinical use in the pharmaceutical market. But their efficacy in arthroscopic rotator cuff repairs remains elusive. To determine their efficacy, we performed a comparative analysis of the effects of two hyaluronate/carboxymethylcellulose (CMC)-based anti-adhesive agents, Protescal and Guardix. METHODS: We recruited a total of 256 patients who had received an arthroscopic rotator cuff repair at our hospital between January 2014 and March 2015. Among them, 96 patients fulfilled the study's selection criteria and were enrolled as the final population sample. Thirty patients who had received a postoperative injection of Protescal were allocated into Group A. Another 30 patients who had received a postoperative injection of Guardix were allocated into Group B. As controls, 36 patients who did not receive any injection were allocated into Group C. The patients included in this study were aged between 19 and 75 years. For the clinical assessment, we measured the following clinical parameters—the visual analogue scale for pain (PVAS), the American Shoulder and Elbow Surgeons (ASES) score, and the constant score, as well as passive range of motions (ROMs)—at three time-points (preoperatively, 2-month postoperatively, and 6-month postoperatively). RESULTS: We found that Group A compared to Group B tended to show a swifter recovery in passive anterior elevation and in internal rotation by the 2-month postoperative follow-up, but the differences were not statistically significant. CONCLUSIONS: We found that the effects of HA/CMC-based injections were minimal after arthroscopic rotator cuff repairs.

In open wounds of the hand that have exposed bone or tendons, management may be difficult. Compared with conventional cutaneous pedicle flaps, the fascial radial flap transfer has several advantages : (1) one operation is required by one operating team reliably and easy to perform, (2) the appearance is not bulky, (3) the donor area is closed primarily, and (4) the hand is free for early motion of the shoulder and the elbow. One potential disadvantage is the permanent loss of the contribution of the radial artery to the circulation of the hand. One case of the fascial radial flap transfer was performed at the Department of Orthopaedic Surgery of Hanyang University Hospital, and satisfactory result was obtained.

OBJECTIVE: To evaluate the effects of estrogen replacement therapy and pamidronate on the bone metabolism in the postmenopausal women. METHODS: This prospective randomized clinical trial examined the effects of oral pamidronate and conjugated equine estrogen, in combination and seperately, on biochemical markers of bone turnover in 140 women with low bone mass. Treatment included pamidronate (group I, n=50), or conjugated equine estrogen (group II, n=50), conjugated equine estrogen plus alendronate (group III, n=40) for 12 months. Biochemical markers of bone turnover were also measured at months 6 and 12 months. RESULTS: Serum osteocalcin and urinary deoxypyridinoline in Group I, Group II and Group III decreased signifiantly at 12 months of treatment (p<0.05). But total alkaline phosphatase decreased significantly during the treatment in Group III, but not in Group I and Group II. CONCLUSION: The combined treatment with pamidronate and conjugated equine estrogen is more effective in postmenopausal women with osteoporosis by decreasing bone biochemical markers.

Herein we report a case of lentigo maligna that evolved into lentigo maligna melanoma. Fifteen years ago, the patient developed a pigmented lesion on the right cheek. The lesion progressed slowly, and 2 months ago, a black nodular lesion was developed in the periphery of the pigmented lesion. Histopathologic examination of the lesions revealed findings consistent with lentigo maligna and lentigo maligna melanorna. She had been performed wide excision and cheek flap for reconstruction.

BACKGROUND: Handgrip and cold pressor test may increase the afterload of the heart. And in left ventricular hypertrophy, it is known that mitral flow pattern is affected by decreased left ventricular compliance. We investigated the effects of handgrip and cold pressor test on mitral flow pattern in patients with left ventricular hypertrophy. METHODS: Handgrip and cold pressor test were performed in 12 subjects with left ventricular hypertrophy and in 14 healthy normal subjects. In supine position, blood pressure, heart rate and Doppler echocardiographic parameters(early peak flow velocity : E, atrial peak flow velocity : A) were obtained at rest, 1 and 3 minutes after the onset of tests respectively. RESULTS: In both groups, handgrip and cold pressor test increased blood pressure slightly without a statistical significance. In left ventricular hypertrophy group, there were significant increments in heart rates at 1 minute of handgrip (78+/-12min-1, p<0.001) and cold pressor test(77+/-7min-1, p<0.05) as compared to that at rest (73+/-12min-1). Mitral flow velocities did not show significant change after the tests in control group. A waves after 1 minute of handgrip(85.2+/-18.4cm/sec, p<0.05) and cold pressor test (87.3+/-17.8cm/sec, p<0.001) showed significant increases as compared to that at rest (79.1+/-14.9cm/sec) in left ventricular hypertrophy group whereas E waves did not. CONCLUSION: Although handgrip and cold pressor tests did not affect the mitral flow significantly in control group, each test raised A waves in left ventricular hypertrophy group. These results suggest that increased A waves may be due to a rise in afterload and decreased left ventricular compliance caused by handgrip and cold pressor test in left ventricular hypertrophy group.
