A clinical observation was made on 216 cases of genitourinary tract tumors of the impatients in the Department of Urology, Chosun University Hospital during the 10 years, from January 1972 to December 1981. The results were as follows: 1. During this period, of 1282 cases hospitalized, 216 cases (180 males, 36 females) had tumors of the genitourinary tract, at the rate of 16.8%. 2. The male to female ratio was 5:1 (180:36). 3. The majority of the patients(88.4%) were distributed over age of 40 years. 4. The prostate was the most commonly involved organ (51.3%) and the tumors of the bladder, kidney, testis, penis, pelvis, ureter, urethra were in order. 5. Histopathologically, B.P.H. was observed in 43.1% of all operative tumors, transitional cell carcinoma of bladder in 28.1% and renal cell carcinoma in 5.6%. 6. Operations were performed in 160 patients (74.1%).

PURPOSE: High flow rate (FR) and pressure limit (PL) strategy with time-cycled pressure-limited (TCPL) ventilator is employed routinely in the neonates. Theoretical basis of this strategy is the two-compartment theory that the lung with acute respiratory failure consists of units with different compliance and resistance. But such constant pressure strategy has the risk of ventilator induced lung injury. We compared the ventilatory indices and clinical outcomes of two different strategies, high FR-constant pressure and low FR-constant FR in the ventilator care of the neonates with acute respiratory failure. METHODS: For the neonates born in our hospital and treated with mechanical ventilation from March to August in 1997, two different ventilator strategies were employed randomly with flow control ventilator. In the high-FR group, the FR was fixed at 10 L/ min and the PL was adjusted according to the arterial blood gas analysis (ABGA) results. In the low-FR group, the FR was adjusted to 10 mL/kg of tidal volume. Sixty neonates were enrolled, 32 in high-FR and 28 in low-FR group. Ventilatory indices and clinical outcomes were statistically cornpared in the two groups. RESULTS: Perinatal factors were not different in the two groups. Initial ventilator settings, ABGA results and ventilatory indices were not different. The tidal volume, fraction of inspired oxygen, peak inspired pressure and oxygenation index were higher and dynamic compliance was lower in the high-FR group compared to the low-FR group after 3 to 72 hours of ventilator care. In clinical outcomes, incidences of pulmonary interstitial emphysema, pneumothorax and chronic lung disease were significantly lower in the low-FR group. CONCLUSION: Low-FR with constant FR strategy resulted in better clinical outcomes in the ventilator care of neonates. We conclude that constant FR strategy prevents damage of the better compliant lung units and decreases the incidence of acute and chronic complications of ventilator care.

A study has been made on the skin response of mouse hind limb to radiation to evaluate the difference of skin response to superfractionation and conventional fractionation schedules, and to optimize the time interval betweenfractions and the dose per fraction in the superfractionated irradiation. 96 mouse hind limbs were dvided into 12groups and were irradiated with 10 consecutive fractions by intervals of 6, 12 or 24 hours and dose per fractionsof 400, 500, 600 or 700 rads. The skin changes of the irradiated hind limb were observed for 30 days and the skin response were analyzed. The results are as follows; 1. There was no significant difference of early skin response along the time interval, from 6 to 24 hours, up to 600 rads per fraction. 2. Mean duration to maximum skin reaction in superfractionation (15.48±2.80 days) is shorter than in conventional fractionation (18.05±3.20 days)by 2.57 days. (p<0.05). 3. Optimum time interval betwen fractions in superfractionation may be 6 hours or less. 4. Optimum dose per fraction in superfractionation may be 500 rads or less.

Cardiac rupture following blunt thoracic trauma is rarely encountered, since it commonly causes death at the scene. With advances in critical care, blunt cardiac rupture has been successfully treated with well-organized team approach including an emergency physician, anesthesiologist, and cardiac surgeon. We encountered a patient with blunt cardiac rupture of the junction of the superior vena cava and right atrium that extended 7 cm to the right ventricular junction. The patient was successfully resuscitated after a closed thoracostomy and pericardiocentesis with fluid loading. Cardiac injury was repaired via mid-sternotomy without cardiopulmonary bypass. The patient recovered without complications and was discharged on the 7th day after surgery.

A clinical observation was made on the non-visualizing kidneys of the inpatients and outpatients in the Department of Urology, Chosun University Hospital during the period from January 1979 to December 1981. The results were as follows. 1. IVP was performed on 849 cases. Among these 131 cases revealed non-visualizing kidney at the rate of 15.4%. 2. Male and female was in the ratio of 1.4:1 and the largest percentage (26%)of the patients was in the fourth decade. 3. Of the causes of non-visualizing kidney, the parenchymal origin was more common than obstructive origin and the renal tuberculosis was the most common disease (43 cases). 4. About a third of 131 non-visualizing kidneys showed abnormal renal function. 5. Operation was performed in 93 patients (71%).

Purpose: To determine the incidence and the time to failure of repaired short external rotator muscles through aposterolateral approach in total hip arthroplasties; and to describe the correlation between failure of the repaired short external rotator muscles and the hip dislocation rate. Materials and Methods: Between January 2003 and October 2003, 51 patients (55 cases) were treated with primary, uncemented total hip arthroplasties. The average patient`s age was 51 years (33 men, 19 women). After the short external rotator muscles were repaired, two 26-gauge wires were stitched as a marker to the abductor tendons and short external rotator tendons. The distance between the two opposing reference points was less than 1.2 cm. The distance between the markers was determined on radiographs that were obtained 1 day, 2 weeks, and 3 months post-operatively. A distance of more than 2.5 cm, or an invisible one, indicated failure. Results: Of a total of 52 repaired short external rotator muscles, 45 (86.5%) failed. Twenty-five(48.1%) failed within the first day, 15 (28.8%) within 2 weeks, and 5 (9.6%) within 3 months post-operatively. Regardless of the time of failure of the repaired short external rotator muscles, postoperative hip dislocations did not occur. Conclusion: The repair of short external rotator muscles after total hip arthroplasties has a high failure rate and contributes little to the prevention of hip dislocations.
