Many authors have been reported that the abdominal trauma, especially injury of the liver and spleen, is frequently found with lower rib fractures, below the ninth rib fractures and the incidence was about 20 to 30%. In cases of rib fractures, Intra- abdominal organs may be injured in the higher rib fractures than the ninth because the diaphragm is elevated at the level of filth intercostal space in expiration period and the intra-abdominal lesions are often delayed evaluated due to the pain of the fractures and masked by the other injuries of the head and the extremities. So above reasons, we were often questioned what the level of rib fracture we must evaluate the intra-abdominal injury was? So we investigated 452 patients with rib fractures who visited our emergency medical center from 1995, January to 1996, December and divided into two groups according to the prescience of intra-abdominal organ injuries by each the level of rib fractures. The number of patients with intra-abdominal organ injuries were 75(16.6%) and the most frequently damaged organ was the liver(25 cases, 33.3%). We calculated the statistical values of each level of rib fractures by the Chi-Square method and got a result that the level of rib fracture we must evaluate the intra-abdominal injuries was the sixth rib fracture. Therefore, if we will meet the patients with rib fracture below the sixth, we must have attentions to the intra-abdominal injuries and evaluate the abdomen closely with various diagnostic methods.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.

In cases of L4-5 spinal fusions, L5-S1 segment used to be included in the fusion traditionally for fear of progressive deterioration of the lumbosacral motion segment after fusion above. The purpose of this study was to evaluate the advisability of extension to L5-S1 segment in cases of L4-5 fusion for an isolated pathologic condition in L4-5 sement. A retrospective review of 72 patients with spinal fusion for an isolated pathologic condition in L4-5 segment was undertaken to compare the clinical results and adverse effects in two groups. One group consisted of 39 patients with floating L4-5 fusion(SF), and the other group consisted of 33 patients with L4-S1 fusion(LSF). The age, pathologic condition at L4-5, and the fusion method(lateral fusion) were matched in two groups. The mean follow-up period was 43.6 months(ranging 24-69 months). Comparisons were made for operative problems, post-operative complications, the amount of changes in angular motion at the adjacent segments to fusion at the last follow-up compared to the pre-operative motion, and the clinical results of treatment. The LSF group took 38 more minutes and lost 245 grams of more blood in averages to complete the additional surgical procedures compared with those in SF group. Several considerable post-operative complications were one deep infection in SF group and three metal failures of sacral fixation with subsequent two fusion failures in LSF group which were mostly concerned with the sacral fixations. The changes of angular motion at follow up compared to pre-operative motion in SF group were 1.5° gain in average (ranging 3° loss-6° gain) in L3-4 segment and 0.6° gain in average (ranging 5° loss-5° gain) in the L5-S1 segment. Those in L3-4 segment of LSF were 2.8° gain in average (ranging 2°-loss 9° gain). Therefore the higher stress and subsequent degeneration are more likely expected above the L4-S1 fusion rather than below the L4-5 fusion. The satisfactory clinical results were 89.7% in SF group and 87.9% in LSF group without significant difference between two groups. In conclusion there is no need to include the L5-S1 segment in the L4-5 fusion when the pathology is limited to L4-5 segment.

A most common site for the isthmic spondylolisthesis is at fifth lumbar vertebra(L5) and far less at fourth(L4). The pathogenic lesion in the pars interarticularis is essentially the same in LA and L5 isthmic spondylolisthesis, but the clinical characteristics may differ each other according to their anatomical and biomechanical differences. A retrospective review of 24 patients of LA(study group) and 27 patients of L5(control group) isthmic spondylolisthesis was undertaken for their medical records and radiographs to compare the clinical characteristics in each groups. Included in each groups were all patients who were surgically treated during the same period and followed for more than two years after surgery. In the study group, 18 of 24 patients were females having an average age of 42.5 years(ranging 34-65), while in the control group, 17 of 27 patients were males having an average age of 38,1 years (ranging 13-59). The symptoms were severe leg pain in most of the study group, but in the control group, the leg pain and back pain were equally complained. The degrees of slip were similar in two groups, but a narrowing of dise space at slip segment was more prominent in study group. The lateral radiographs taken in flexion and extension revealed more changes of slip in study group (4.7mm in study group vs 2.8mm in control group in averages), and more angular motion at slip segment in study group unless the dise space is not severely narrowed. A spinal stenosis in CT findings was disclosed in almost all patients of study group and in 18 patients of control group. The sizes of L5 transeverse process were bigger than twice as those of L4 in 17(70.8%) patients including 9(37.5%) sacralizations of L5 in suty group, while in control group they were only 8(29.6%) patients with no sacralization. The heights of intercreastal line revealed no difference in two groups. The surgical procedures in study group were fusion only in two and decompression with fusion in 22(91.7%) patients and those in control group were fusion only in 11 and decompression with fusion in 16(59.3%) paticnts. The satisfactory results of treatment were in 21(87.5%) patients of study group and 25(92.6%) patients of control group without significant difference between two groups. In conclusion, the L4 spondylolytic spondylolisthesis compared to L5 lesion was more unstable and developed spinal stenosis more often. The surgical treatment and decompression procedure were also more needed in L4 lesions particularly in agend women.

Stress urinary incontinence is mainly treated by major surgical procedures. Bolstering the urethra with injectable compound is an attractive, although not new, procedure for stress urinary incontinence. Recently it has been popularized to use the autologous fat for injection. A total of 6 women with stress urinary incontinence underwent periurethral injection of autologous fat. Patients' age ranged from 41 to 69 years( mean 55.8). The fat was harvested from the low abdominal wall by liposuction unit. Follow up was 2 to 10 months( mean 6.8). of the patients, 5(83%) are cured, 1 is improved significantly( from Grade III to I). We conclude that the periurethral autologous fat injection is a reliable, safe, low-cost, and high benefit procedure.

Whether indwelling urethral catheter should be removed after urethroplasty or visual internal urethrotomy in patients with posterior urethral injured is still controversial. From May 1990 to February 1995, 28 patients with posterior urethral injury underwent retrograde pericatheter urethrography for the purpose of the evaluation of urethral continuity in the timing of the removal of indwelling urethral catheter. The indwelling catheter was removed in 24 patients whose urethra did not have any extravasation, and 4 patients had detectable extravasation. We conclude that retrograde pericatheter urethrogram is the most useful radiologically diagnostic method to evaluate in the timing of the removal of indwelling urethral catheter and to obtain the objective parameter of urethral patency in posterior urethral injured patients, postoperatively.

Paralytic shellfish poisoning results from consumption of mollusks that have fed on dinoflagellates capable of producing neurotoxins such as saxitoxin. The saxitoxin is concentrated in the shellfish and acts by decreasing sodium-channel permeability, thereby blocking neuronal transmission in skeletal muscles. Symptoms including paresthesia, perioral numbness, perioral tingling, nausea, vomiting, extremity numbness, extremity tingling, dizziness, ataxia, dysphagia, and weakness have been reported. In serious cases, respiratory hold may occur up to 6~24 hours after ingestion. Generally, the treatment for paralytic shellfish poisoning is supportive care, but mechanical ventilation is needed in serious cases acompanied by respiratory hold. We experienced two cases of paralytic shellfish poisoning. Respiratory hold was presented in one case and only mild paresthesia in the other case. After supportive management, including mechanical ventilation in former case, both patients were discharged without sequalae.

We report a case of tibial nerve palsy after pneumatic tourniquet application for 40 minutes with a tourniquet pressure of 300 mmHg. A 45 years old woman with morbid obesity and diabetes mellitus was underwent partial lateral meniscectomy of left knee. Even 3 months after the event, nerve palsy was not completely recovered. The case underscores the necessity of being aware of the potential for complications associated with tourniquets, despite following recommended guidelines of tourniquet time and pressure. Especially, in the patients with metabolic diseases such as diabetes mellites or obesity, safe duration of tourniquet application may be shortened.

We report a case of massive retroperitoneal hemorrhage from a spontaneous rupture of a renal angiomyolipoma in a 35 year-old man, that appeared unilateral and solitary tumor without stigma of tuberous sclerosis. He experienced a sudden onset severe pain on the right flank, but had no history of specific associated diseases or factors such as trauma or stone. The patient presented with a clinical picture of shock because of massive hemorrhage in despite of the emergency care and was treated by right total nephrectomy. Herein we review briefly the clinical presentation, diagnosis and management of renal angiomyolipoma.

OBJECTIVES: To examine the in vitro interactions of blastocyst attachment using type I collagen. MATERIALS AND METHODS: ICR mice were used and follicular growth was stimulated by pregnant mare serum gonadotropin and human chorionic gonadotropin. On day 4 of pregnancy, the uteri were removed and blastocysts were flushed. Mixtures of 1mL sterile water, 0.5mL DMEM, 2mL type collagen solution and 0.5mL 0.1M NaOH were prepared and transferred to an incubator where the collagen solution polymerized. Blastocysts were transferred to dishes previously coated with type I collagen. CMRL 1066 was used as the basic culture medium. It was supplemented with 1mM glutamine and 1mM sodium pyruvate plus 50 IU/ml penicillin and 50 mg/ml streptomycin. During the first 4 days the culture medium was supplemented with 20% fetal calf serum and thereafter with 20% heat inactivated human cord serum. All blastocysts were initially cultured for 2 days without media change. After 2 days, fresh medium was renewed daily. The stages of embryo growth were examined and recorded everyday under a dissecting microscope and classified according to the standard in vivo criteria set forth by Witschi. RESULTS: By 48h, nearly all blastocysts had attached to the surface of collagen pad. Following adhesion to the collagen pad, the blastocysts maintained their 3-dimensional integrity in contrast to control. The embryos in collagen pad were not flattening and kept polarity and spherical shape during culture. The polar trophoblast invaded the type I collagen downward unlike the horizontal growth in control. In the developmental stage of mouse blastocyst, there were significant differences between control and type I collagen group during day 4 and 5 culture. CONCLUSION: Blastocyst development was better in type I collagen group than control. Therefore, in vitro culture study using type I collagen could provide improved model for the establishment of blastocyst implantation study.
