Calcaneus was the most commonly involved bone among the tarsal bone fracture. Many different methods have been tried for the treatment of fractures of the calcaneus in order to search for better results. But there is no general agreement on the treatment of the fracture of the calcaneus, especially involving the subtalar joint. From Jan. 1986 to Jan. 1990, 25 feet in 20 patients of calcaneal fractures involving the subtalar joint were treated by closed reduction & percutaneous pinning at the Dept. of Orthopedic Surgery, Chosun University Hospital and the results were as follows; 1. Of these intra-articular fractures, 15 fractures were tongue type and 10 fractures were joint depression type by Essex-Lopresti classification. 2. According to the Salama unit system, the results of treatment were excellent or good in 11 cases of 15 tongue types and 6 cases of 10 joint depression types. 3. The results were excellent in which reduction is achieved near anatomical reduction. 4. Even if the joint depression type fracture which is not severely comminuted, the treatment with closed reduction & percutaneous pinning is thought to be good method.

Since Klemm introduced the concept of antibiotic-containing bone cement for the treatment of chronic osteomyelitis, a number of studies have demonstrated the positive results of this therapy. It has been proved that antibiotic-containing bone cement continuously releases high levels of atibiotics locally into the infected and avascular wound environment. Antibiotic-containing bone cement provides several distinct advantages over irrigation-suction drainage. The major objective of this study is to analyze the results of therapy using antibiotic-containing bone cement beads for chronic osteomyelitis. The authors analyzed 21 cases of chronic osteomyelitis in patients who had been treated by saucerization and antibiotic-containing bone cement beads at Chosun University Hospital, between February 1990 and January 1993. Each patient's case was followed for at least thirteen months after operation. The results are as follows: 1. The causes of osteomyelitis were postoperative complications(10 patients), open fracture(8 patients), and hematogenous osteomyelitis(3 patients). 2. Staphylococcus aureus was the most common organism causing osteomyelitis, followed by Pseudomonas. 3. The femur was the most common location of lesion(11 patients) followed by the tibia(7 patients), the humerus(2 patients) and the ulna (1 patients). 4. Pus drainage was stopped in 13 cases with one insertion of the beads, in 2 cases with two insertions and in 2 cases with three insertions. 5. Therapy using antibiotic-containing bone cement beads can be regraded as an effective method of increasing local antibacterial activity by releasing the antibiotic into surrounding tissue over a continuous period in the treatment of chronic osteomyelitis. Antibiotic-containing bone cement beads are useful in the treatment of chronic osteomyelitis.

A case of Fetus-in-fetu is reported. The patient was a 8 month-old-boy with a tumor in the left upper retroperitoneum. The characteristic feature of the specimen consisted of vertebral column including pelvis, both upper and lower extremities, neural canal and brain tissue, and well formed large intestine.

PURPOSE: MgSO4 was used to evaluate the clinical effects in the treatment of severe persistent pulmonary hypertension of the newborn(PPHN). METHODS: Seven newborn infants with severe PPHN, and a persistent elevation of AaDO2(Alveolar-arterial oxygen tension difference) above 610 mmHg for more than 8 hours despite the aggressive conventional therapy were included. A loading dose of 200 mg/kg MgSO4 was given intravenously over 20-30 minutes, followed by continuous infusion of 20-50 mg/kg/hour. Vital signs, arterial blood gases, serum electrolytes, calcium and magnesium, and ventilatory setting were measured and recorded before MgSO4 was given and periodically thereafter. Severity of impairment of gas exchange was evaluated by AaDO2 and oxygenation index(OI). RESULTS: Mean gestational age and birth weight of seven infants were 38+5 weeks and 2,949844 grams, and one of them was a premature infant with gestational age of 27 weeks, and birth weight of 1,096 grams. There were six males and one female. Four infants were outborn. Four infants were presented with meconium aspiration syndrome, one with birth asphyxia, one with respiratory distress syndrome, and one with subdural hemorrhage. Before the start of the MgSO4 treatment, the mean AaDO2 and OI of seven infants were 638.8+/-10.8 mmHg and 43.811.2, respectively. During the treatment AaDO2 and OI significantly decreased to 538.4+/-114.5 mmHg and 13.4+/-9.4 within 24 hours(P< 0.05). Hypermagnesemia was noted in 7 infants, hypocalcemia in three, bradycardia in five, and hypotension in two. Only one infant was discharged against medical advice, and remaining six survived. CONCLUSION: MgSO4 may be considered as an alternative treatment of severe PPHN when other conventional treatments fail, are contraindicated, or not available.

Minoxidil is a potent direct-acting peripheral vasodilator indicated in the management of severe or refractory hypertension. Well-known adverse effects include reflex tachycardia, fluid retention and hypertrichosis. This drug has also been reported to cause pericardial effusion in about three percent of nondialyzed patients with compromised renal function and to cause cardiac tamponade less frequently. Many studies have reported that the mean duration of therapy that caused pericardial effusion was about 8 months (range 1 month-53 months). We report a case of cardiac tamponade in nondialyzed patient with chronic renal failure receiving minoxidil for 10 years. A 58-year-old female was admitted to our hospital with dyspnea of NYHA III. She was a chronic renal failure patient without dialysis treatment and received kidney transplantation from cadaver donor and was dignosed chronic rejection in 1994. Minoxidil 10mg has been used for past 10 years. Lasix has been used for past 2 years, with dosage of 40mg to 240mg. On admission, blood pressure was 90/60mm Hg. Cardiomegaly was seen on chest radiograph. The two-dimensional echocardiogram showed a large amount of pericardial effusion. Emergency treatment with pericardiocentesis removed 2500ml of straw- colored pericardial fluid and resulted in marked improvement of dyspnea and stabilized blood pressure. The minoxidil was discontinued. The evidence of pericardial effusion was not seen for 12 months after minoxidil had been discontinued.

Mitral valvular orifice area is important for the evaluation of prognosis and treatment of patients with mitral valvular stenosis. Until recently, Gorlin's formula using cardiac catheterization has been utilized in the measurement of mitral valve area, but it is invasive and impractical to examine repeatedly. Recently 2-Dimensional echocardiography appeared to be a practical and useful substitute in measurement of valve area and also it is economical and has no risk to patients. In 31 patients with mitral valvular stenosis examined at the echocardiography room of Busan national University Hospital from March 1982 to March 1983, we measured the mitral valve area with 2-Dimensional echocardiography and evaluated its relationship with the left ventricular functions measured on M-mode echocardiogram. Among many parameters on M-mode measurements EF slope, excursion amplitude and the ratio of left atrial dimension to aortic root dimension were rather helpful for the assessment of severity of mitral valvular stenosis than other parameters. And each relationship with the valve area showed correlation coefficient of 0.60, 0.05 and -0.58, respectively.

Excess hair growth in unwanted areas may result from heredity, endocrine disease, or drug therapy. Conventional methods of hair removal include shaving, wax epilation and chemical depilatories that frequently cause side effects such as contact dermatitis and that also have temporary effects. Electrolysis is a well-established medical method for permanent destruction of terminal hair follicles. However, this method is tedious and efficacy has been reported to range from 15-to-50% permanent hair loss. The evolution of the laser use for hair removal continues a year after Food and Drug Administration (FDA) approval of the first laser for these applications. The authors have experienced hair removal utilizing a long-pulsed alexandrite laser. This laser system employs the principle of thermokinetic selectivity, a revolutionary concept. The principle of thermokinetic selectivity involves the use of lasers with pulse durations below the thermal relaxation on a the large target such as the hair folllicle (40-100 msec), and significantly longer than the thermal relaxation time of smaller structures of the same chromophore (melanin) in epidermis (3-10 msec). The study was based on 76 patients treated with 20 msec pulse duration laser set to energy densities of 17-21 J/cm2. Treated areas included arms, legs, beard-chin, upper lips and bikini lines. Gross observation showed leaching of hair color, decresed size of the skin pores, easily broken hair shafts, and elimination of hair. Therefore, it can be assumed that the majority of hair follicles were destroyed by this procedure, Side effects included intermediary risk of hyperpigmentation and blister. Over 80% of treated patients were satisfied with the results. As the process of research and clinical application continues, we need the long-term results of this laser system to ensure its efficacy.
