PURPOSE: We studied the diagnostic significance of bone scan in evaluation of bone metastasis by lung cancer, prevalence rate, and the causes of false positive bone scan and soft tissue accumulation of bone seeking agent. MATERIALS AND METHODS: The subject included 73 lung cancer patients with bone scan. We analyzed the frequency of bone metastasis, its distribution and configuration, and any relationship between bone pain and corresponding region on bone scan. The positive findings of bone scan were compared with simple X-ray film, CT, MRI and other diagnostic modalities. The false positive bone scan and the soft tissue accumulation of bone seeking agent were analized. RESULTS: The positive findings on bone scan were noted in 26 cases(36%) and they were coexistant with bone pain in 30%. The correspondance between bone scan and bone X-ray was 38%. False positive bone scans were seen in 12 cases(16%), which include fracture due to thoracotomy and trauma, degenerative bone diseases, and bifid rib. Accumulation of bone seeking agent in soft tissue were seen in 13 cases(18%), which included primary tumor, enlarged cervical lymph node, pleural effusion, ascites and pleural thickening. CONCLUSION: Bone scans should be carefully interpreted in detecting bone metastasis in primary malignancy, because of the 16% false positivity and 18% soft tissue accumulation rate. It is very important to note that the correlation between bone pain and positive findings of bone scans was only 38%.

There are many procedures for treatment of injuries of acromioclavicular separation, but still controversies concerning the best management of these injuries. From March 1981 to August 1984 at Masan Korea Hospital, twelve cases were treated by technique of modified Phemister method, two cases by Dewar and Barrington method, two cases by Stewart method, one case by Neviaser method, three cases by skillful neglect method and two cases by shoulder harness immobilization. The following results were obtained. 1. These injuries were more prevalent in male and more in right side. 2. The most common cause of injuries was traffic accident and followed by falling from the height. 3. Three cases were grade 2 and nineteen cases grade 3 by Allman's classification. 4. We treated these injuries by operative method in seventeen cases and non-operative method in five cases. 5. There were good functional results of treatment in operative method. 6. There were two cases of superficial wound infection, two cases of migration of K-wire and one case of recurrence of deformity in operative method, and two cases of shoulder stiffness and 2 cases of recurrence of deformity in non-operative method.

Apert described acrocephalosyndactly as a clinical entity in 1906. The classic description of this syndrome includes patient with a combination of acrocephaly and syndactyly of either fingers, toes or both. More than 200 cases have been reported in the world literature. Authors experienced on case of the classic pattern of Apert syndrome and treated surgically for syndactyly. This one case was reported on this paper with brief review of the relevant literatures.

Twenty-six cases of fracture of the femur and tibia on the same leg were treated in Masan Koryo General Hospital during the period 1981 1986. We studied all of these patients, divided by four groups according to the method of treatment, retrospectively with analysis of treatment and end results. The results were as follows : 1. Twenty-two patients were male and four patients were female. Of twenty-six patients, eighteen patients were at their third and fourth decades. 2. The main cause of injuries was traffic accident; 23 patients(88%). 3. The most common concomitant injury was fracture and dislocation in other site(14 cases). The fat embolism developed in one case and one patient had died due to head injury. 4. The average healing time of fracture was 17 weeks in femur and 20 weeks in tibia in group three, that was most rapid of all groups. 5. A good or excellent functional result was achieved in 87% of the patients treated with internal fixation of both fracture, 75% of the patients with internal fixstion for the femur fracture and external fixation for the tibial fracture, and 25% of the patients trested conservatively.

PURPOSE: In order to evaluate microstructural changes after shock wave exposure, gross, light microscopic and transmission electron microscopic findings were analyzed with rabbit gallgladders. MATERIALS AND METHODS: A preliminary study(2 rabbits) was performed to determine the dosage intensity of shock waves needed to inflict damage, using a EDAP LT 01 piezoelectric extracorporeal shock wave Iothotriptor. The gallbladders of three different groups of rabbits were given shock waves of various intensity. A storage value of 100, 50, 25 at rate of 20/sec under 80% power were given to group I (4 rabbits), group II( 4 rabbits), and group III(3 tabits), respectively. The rabbits were sacrified 6--12 hours later. RESULTS: The observed pathologic changes in the transmission electron microscopy were vaculization of cytoplasm and swelling of epithelial cells with dilatation and structural alteration of intracellular organelles, especially endoplasmic reticulum. Cell membrane rupture and necrosis were observed at the markedly affected area. The structural changes of intracellular organelles were minimally found at a storage value of 25. However, above pathologeic changes with dilatation and structural alterations of endoplasmic reticulums were more profund at value of 100. CONCLUSION: Early histologic changes induced by shock waves are dose dependent and the findings of cellular damage caused by ESWL might be explained as above.

Syphilitic aortitis, passing out of our mind, is the most common systemic manifestation of late syphilis and is more typically manifestated 10 to 30 years afterward. This diagnosis has been made less frequently in recent decades than in the past, because of public awareness of syphilis and screening program. Treponema pallidum lodge within vasa vasorum, especially ascending aorta cause the histologic changes, which are responsible for the three major forms of symptomatic cardiovascular syphilis, including aortic insufficiency, coronary ostial stenosis, and aortic aneurysm. We experienced a case of syphilitic aortitis with aortic insufficiency and aortic aneurysm in a 48-year-old man presented with progressive dyspnea. Echocardiography, chest CT, and later surgical correction were performed and surgical specimen revealed the histologic finding consistent with syphilitic aortitis. We report this case with a review of the literature.

This experiment involved 12 rabbits of both sexes, weighing 2.1 kg. After anesthesia, the kidneys were exposed, isolated and cannulated in the renal artery, ureter and sometimes in the vein as well. The kidney were perfused through the renal artery with Krebs-Henseleit solution, which were then filtered to be free of particles, gased with 95% O2-5% CO2, and kept at 37 degrees C. We measured RBCs concentrations by means of Coulter Counter in the venous outflow collected, and plotted them against the volume perfused. Using 2 different flow rates, 9 ml/min (group I) and 19 ml/min (group II), we found that the RBCs decreased in a multiexponential decay fashion and a biophysical model for each flow rate was constructed. These models indicated that there were more cell stores (2.20 x 10(10)) in the fast compartment of group II than in group I (1.72 x 10(10)). This difference is not statistically significant, but certainly coincides with urine flow collected from ureter cannula during perfusion. Our present data clearly suggest that in order to clear 99% blood cells out of 10-12 gm rabbit kidneys, at least 3-6 ml of cell free perfusate is required while clearing the whole blood cells out of human kidneys (200-240 gm) may need 600 ml or more. Thus, we recommend that at least 600 ml of perfusate should be used to clear most of the blood cells in the renal vasculature before renal transplantation is performed.

In most cases, extubation may be safely performed in the operating rooms. However, some cases need leaving the endotracheal tube in place until the patient's condition is appropriate, usually in the Postaneshesia Care Unit (PACU) or Intensive Care Unit (ICU). We retrospectively reviewed the recovery room record of 4,241 patients who performed on operation under general anesthesia at Inha Hospital from January 1993 to December 1993, and then examined into details how many factors are influenced to the time of extubation following surgery. The results were as follows; 1) The overaU frequency of delayed extubation (or PACU extubation) was 9.8% (423/4,241). 2) The surgical disciplines which had the highest number and incidence of delayed extubations were the general surgery (172 cases) and dental surgery (25%), respectively. 3) According to sex, the male patients (243) outnumbered the female counterparts (180). 4) According to age, delayed extubation was most common among infants (<1 year of age) (21.4%). 5) According to operation site, delayed extubation occurred most commonly among operations involving upper abdominal regian (36.1%) followed by thoracic region (22.9%). In conclusion, extubation should be performed when the patient is nearly fuUy awake, of acceptable respiratory rate and depth, and when the effects of muscle relaxants have been fully reversed.
