The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

BACKGROUND: Echocardiographically detected left ventricular(LV) hypertrophy is a risk factor for cardiovascular morbidity and mortality. A better understanding of the determinants of LV mass may aid in strategies directed toward the promary and secondary prevention of LV hypertrophy and its consequences. Previous studies have reported that male gender, arterial blood pressure(BP), obesity, age, aortic valvular stenosis, dietary sodium, endocrine factors, and physical activity are positively correlated with LV mass. Of these determinants male gender, hypertension, and obesity are well known but age and blood pressure in healthy adults are controversial. To assess the determinants of LV mass, the relation of 2-dimensional(2D) echocardiographically determined LV mass to body mass inedx(BMI), age, sex, casual BP, and 24 hour ambulatory blood pressure(ABP : systolic, diastolic, and mean BP of 24 hour, day-time, and night-time) was examined in healthy adults. METHODS: The study population consisted of 200 healthy adults who were normotensive, nonobese, and had no evidence of cardiovascular disease(range in age from 20 to 69 years, five decades, 20 men and 20 women per each decade). LV mass was derived from area length method measurements obtained by 2D echocardiography and corrected for height. ABP monitoring was performend over 24 hour(divided into day-time(6am-10pm) and night-time(10pm-6am)periods) with 30 minute inervals. RESULTS: 1) BMI was significantly and independently related to LV mass corrected for height (p<0.001, partial R2=0.31 in men and 0.43 in women). An increase of BMI by 1 kg/m2increased LV mass corrected for height by 1.9g/m in men and 2.0g/m in women. 2) Age was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.15 in men and 0.17 in women). The increments of Lv mass corrected for height per decade were 2.1 g/m in men and 3.4 g/m in women. 3) Gender was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.12), which was greater in men than in women by 6.34g/m. 4) Casual Bp and 24 hour ABP were not significantly associated with LV mass corrected for height in total population and women, and 24 hour systolic BP was significantly related to LV mass corrected for height only in men(p<0.001) with weak partial R2(0.05). CONCLUSION: BMI, age, and male gender were statistically significant and independent correlates of LV mass corrected for height(p<0.001). Maintenance of ideal body weight and normal BP, weight reduction in obese persons and BP control inhypertensive patients may contribute to the primary and secondary prevention of LV hypertrophy and its sequalae.

OBJECTIVE: 1) To evaluate the mid-term efficacy and safety of a permanent nitinol inferior vena cava (IVC) filter; 2) to evaluate filter effectiveness, filter stability and caval occlusion. MATERIALS AND METHODS: A prospective evaluation of the TrapEase IVC filter was performed on 42 patients (eight men, 34 women) ranging in age from 22 to 78 years (mean age 66 years). All patients were ill with a high risk of pulmonary embolism (PE). Indications for filter placement were: 1) deep vein thrombosis with recurrent thromboembolism; 2) and/or free-floating thrombus with contraindication to anticoagulation; and 3) complications in achieving adequate anticoagulation. Follow-up evaluations (mean: 15.4 months, range: 2 to 28 months) were performed at 6- and 12-month intervals after the procedure and included clinical histories, chart reviews, plain film, Doppler ultrasounds, and contrasted abdominal CT scans. RESULTS: In follow-up evaluations, the data analysis revealed no cases of symptomatic PE. There were no cases of filter migration, insertion site thrombosis, filter fracture, or vessel wall perforation. During the study, there was one case of filter thrombosis; early symptomatic thrombosis that was successfully treated in the hospital. Of the 42 subjects, eight died. These deaths were not related to the filter device or the implantation procedure, but to the underlying disease. CONCLUSION: This study demonstrates that the TrapEase permanent IVC filter is a safe and an effective device with low complication rates and is best used in patients with thromboembolic disease with a high risk of PE.

Calcific tendinitis usually occurs in the supraspinatus tendon of the shoulder. Calcific tendinitis of the peroneus longus tendon has not been reported on the Korean journals. Differential diagnosis includes bipartitis os peroneum, os peroneum fracture and peroneal tendinitis. We report a rare case of calcific tendinitis of the peroneus longus tendon which responded well with the conservative treatment.

In order to produce solar retinopathy, the right eyes of Strauge-Dawley albino rats were exposed to sun light(13,1500 lux) for 15 and 30 minutes respechrel(experimental groups), while the left eyes were taped to protect them from solar damages(control groups). In both experimental and control groups. We studies the lnjuries of the retina due to sun llght. The enucleated eyes ln both groups, were examined by light and electron microscopes for histopathologic changes of the retina preceded by the indirect ophthalmoscopic examination under low Illumination. Although there was no definite pathologic change in indirect ophthalmoscopic and light microscopic examinations, rather severe damage was seen at the electron microscopic level. At one day after the experiment, the inner segment of visual cells was relatively well preserved, but the other layers of the retina were markedly damaged. More severe retinal damage was seen in the 30 minute group than in the l5 minute group. At 2 weeks after the experiment, partial recovery of the whole retinal layers was observed, especially in the visual cells. At 4 weeks after experiment, the outer and inner segments of the visual cells were nearly normalized. Considering the results of the experiment, it is evedent that frequent clinical usage of indirect ophthalmoscope, surgical microscope and slit lamp biomicroscope could affect the retina and produce damage ultrastructually, even though no significant abnomalities are found by any other means.

OBJECTIVE: The purpose of this study was to investigate the effect of tribochemical silica coating on the shear bond strength (SBS) of rebonded ceramic brackets using nano-filled flowable composite resin. METHODS: A total of 60 premolars were prepared and divided into 4 equal groups as follows: Tribochemical silica coating (TC) + Transbond XT (XT), TC + Transbond supreme LV (LV), Sandblast treatment (SA) + XT, SA + LV. Treated ceramic brackets were rebonded on the premolars using each adhesive. All samples were tested in shear mode on a universal testing machine. RESULTS: SBS of silica coated groups were high enough for clinical usage (TCLV: 10.82 +/- 1.82 MPa, TCXT: 11.50 +/- 1.72 MPa). But, SBS of the sandblast treated groups had significantly lower values than the tribochemical silica coated groups (SALV, 1.23 +/- 1.16 MPa; SAXT, 1.76 +/- 1.39 MPa; p< 0.05). There was no difference between the shear bond strength by type of adhesive. In the silica coated groups, 77% of the samples showed bonding failure in the adhesive. In the sandblast treated group, all bonding failures occurred at the bracket-adhesive interface. CONCLUSIONS: The result of this study suggest that newly introduced nano-filled flowable composite resin and tribochemical silica coating application on debonded ceramic bracket bases can produce appropriate bond strengths for orthodontic bonding.
