From May, 1971 to June, 1984, we performed extensive saucerization on the chronic osteomyelitis of long bones eradicating all pathologic foci; not only sequestra but sclerotic involocurum and necrotic original cortex embeded by new bone, which was different from the conventional methods such as sequestrectomy or guttering in its extensiveness. Clinical analysis on the base of radiologic evaluation after saucerization was done on the 16 patients; for average 5 years of follow-up. The results obtained were as follows; 1. The angulatory deformity of the long bones after pathologic fracture complicated by the chronic osteomyelitis was not corrected satisfactorily due to the bony sclerosis or hyperostosis at the fracture site, especially in cases of posterior or medial angulation. 2. The recurrence was closely related to the persisting non-sequestered original cortical lesion after incomplete saucerization, which was embeded by the new bone. So to prevent the recurrence the non-sequestered original cortical lesion must be removed completely. 3. The cortical defect after saucerization was restored completely in patients under the age of 14, but which was not the way in patients over the age of 16.

The Q-switched ruby laser has been used in clinics since the early 1980s. It was tried to remove tattoos at first with good effects. Thereafter, some physicians reported the usefulness of the laser in the treatment of some kinds of pigmented lesions such as nevus of Ota, freckles and lentigines. The reason why the Q-switched ruby laser has a lot of effect on tattoos and some pigmented lesions is that the laser has the function of selective photothermolysis on those cutaneous lesions. The authors have treated 185 patients with tattoos and cutaneous pigmented lesions using the Q-switched ruby laser during last 4 years ago. Patients had tattoos, nevus of Ota, freckles, lentigines, melasma, postinflammatory hyperpigmentation, and were followed up over 5 months after the end of the laser treatment. The authors analysed the results and compared them with other's results in Caucasians, and we intended to present a guide of the treatment using Q-switched ruby laser in Koreans. The results were as follows 1. Tattoos showed good results after the treatment because the most of tattoos are black or dark blue in color and cheated by amateur. We repeated the laser treatments with the interval of 2 weeks. 2. Nevus of Ota, freckles and lentigines showed good results after treatment of the Q-switched ruby laser 3. Melasma showed no improvement after the treatment. 4. The treatment of postinflammatory hyperpigmentation using the Q-switched ruby laser must be confined within a part of the lesion at the first visit of patient, because the therapeutic effects were observed in some patients only and the degree of depigmention after treatment was diverse. 5. The most common complication after Q-switched ruby laser treatment was pigmentary change, including hyperpigmentation in most of the cases and hypopigmentation in some cases. However, there was no visible scar or remarkable change of skin texture in all of the cases.

To evaluate the features of pyuria related to the bacteriuria, 140subjects were studied from Jan. 1987 to Dec. 1987. They pyuria was frequently developed from the age 30 to 60 years old, and male to female ratio was 1:1.41. The most common disease was urethrocystitis that was shown 42.8%. Common precipitating factors were urethral catheterization (25%) and urinary tract obstruction (11.4%). Through the observation, symptomatic pyuric patients were 66 subjects (47.1%), and the subjects with significant urine culture were 121 subjects (86.4%). In the urine culture, the most common bacteria was E. coli (41.4%), and the next was Pseudomonas (19.3%). A large percentage of E. coli and Pseudomonas was susceptible of amikin. The pyuria due to S. epidermidis and Accinatobacter was well treated. High therapeutic rate was observed in the acute pyelonephritis (71%) and urethrocystitis (67%). In the persistent urinary tract infection, there were relapsing (22 cases) and recurrent urinary tract infection (16 cases).

OBJECTIVE: For the treatment of carotid cavernous fistula(CCF), transarterial detachable balloon occlusion(DBO) is the method of choice. When it has failed to occlude the fistula, various embolization methods are used to treat the fistula. Transvenous embolization through the superior ophthalmic vein(SOV) is another method of treatment. The venous approach through the SOV after surgical dissection and exposure of this vein has been recommended by some delete, but(here) delete delete(an) alternative treatment method by percutaneous puncture of the SOV without surgical dissection(is described). METHODS: A 19-year-old woman admitted to our hospital two months after accident, presented with proptosis, chemosis, occulomotor and abducens nerve palsies, and bruit of the right eye. The authors tried DBO via transarterial route in initial treatment and the fistula was occluded with subsequent disapearance of bruit. However, 2 weeks later, she complained of recurence of bruit. Transarterial approach was attempted again, but the fistula hole was too small for this approach. The venous approach via SOV by percutaneous puncture was then tried. Puncture was made at the medial one third of the superior orbital rim and the fistula was embolized with Guglielmi detachable coils (GDCs). RESULTS: The fistula was completely occluded and no early and late complications noted. The patient's clinical symptoms were improved within a few days. CONCLUSION: Treatment of CCF by percutaneous puncture of the SOV is an alternative and effective method when other approaches are not feasible.

BACKGROUND: The high pressure zone(HPZ) at the gastroesophageal junction is an important barrier for prevention of gastroesophageal reflux. Smooth muscle layers in the lower esophageal sphincter mainly contributes to HPZ at the throacoabdominal junction. The purpose of this study was to investigate the manometric characteristics of the thoracoabdominal junction in patients after surgical removal of the lower esophageal sphincter. MATERIAL AND METHOD: Twenty two patients with prior esophagogastrectomy(10 Ivor-Lewis method and 12 left thoracotomy) and 30 normal adults(control group) were studied manometrically. RESULT: Esophageal manometry showed a HPZ and pressure inversion point distal to the anastomosis in 12 of 22 patients(2 of 10 patients with Ivor-Lewis method and 10 of 12 patients with left thoracotomy) and a HPZ in 30 of 30 normal adults. The location of HPZ from nostril was not significant different between the two groups(42.5+/-0.9cm in patients and 43.9+/-2.1cm in the control), while the length of HPZ was shorter in patients than in the control(2.13+/-0.6cm vs 2.83+/-0.59cm). By SPT and RPT, pressures of HPZ at rest were lower in patients(13.78+/-1.63mmHg, 28.58+/-6.06mmHg) than in control(20.3+/-4.95mmHg, 42.80+/-15.91mmHg). The HPZ relaxed partially in response to deglutition(84.4% in patient, 90.5% in control group) and contracted in response to increased intra- abdominal pressure induced by leg lifts(HPZ/ Intra-abdominal pressure= 1.81+/-0.23 in patient, 2.13+/-0.58 in control group). CONCLUSION: This study shows an HPZ at thoracoabdominal junction after surgical removal of the lower esophageal sphincter. It may be important to perform a crural myoplasty during esophageal reconstruction after esophagogastrectomy because crural diaphragm acts as sphincter like HPZ at the thoracoabdominal junction.
