PURPOSE: To estimate the incidence and risk of significant renal injury quantitatively in the admitted patients with abdominal trauma. MATERIALS AND METHODS: From January 1992 to July 1997, 511 patients who admitted to departments of urology and general surgery due to major abdominal trauma with and without renal injury were included in this study. The risk of renal injury was defined as the percentage of square of Abbreviated Injury Scale of kidney in the Injury Severity Score(ISS) per each patient. The patients were classified to 5 groups according to the causes of trauma as traffic accident, falls, assault, other blunt and stab Injury, then compared the incidence and risk of renal injury each other. RESULTS: The overall incidence of significant renal injury was 14.9%, and the incidence according to the causes was 27.0%,20.8%, 16.1%, 14.3% and 10.7% in falls, assault, stab injury, other blunt and traffic accident, respectively. The overall risk of significant renal injury estimated by ISS was 15.7% and the risk according to the causes was 26.7%,24.9%, 11.9%,9.9% and 4.9% in assault, falls, traffic accident, other blunt and stab injury, respectively Mean ISS in the patients with renal injury was markedly higher than that of the patients without renal injury(27.5 vs 13.6)(p < 0.01). CONCLUSIONS: Our study shows that both the incidence and risk of significant renal injury in the admitted patients with abdominal trauma can be expected in the probability of 15% or so, and according to the causes, those in the traumatized patients by the assault and falls mark high.

Tissue temperatures were measured by a thermistor-thermometer, at suprachoroid, inner retinal surface and intravitreous portion (1mm deep), during diathermy applications on the scleral surfaces of rabbit eyes. Castroviejo's Electro-surgical Ophthalmic unit Model S-5 was used and power intensity(current) was fixed to 2, and diathermy was applied on the sclera 3mm, 2mm, and 1mm from and above the measuring points. Measurements were performed in the following groups: Group 1: Spark gap power 2. duration of application 2 sec. Group 2: Spark gap power 2. duration of application 3 sec. Group 3: Spark gap power 3. duration of application 2 sec. Group 4: Spark gap power 3. duration of application 3 sec. Maximum rise of temperature was 20.0 degrees C at suprachoroid, 16.8 degrees C at inner retinal surface and 6.6 degrees C at vitreous in Group 4. Temperature rise in vitreous was much lower than that in suprachoroid and inner retinal surface (table II, which revealed percentage of average rise per tissue temperature before diathermy). Highest measuring temperature at inner retinal surface in this experiment was under 60 degrees C, at which vitreous collagen fibrils may coagulate.

Korean Journal of Urology 1998;39(10):972-976
PURPOSE: To evaluate the usefulness and safety of unified technique of vascular control before renal exposure in reconstructive surgery of renal trauma. MATERIALS AND METHODS: From July 1995 to June 1997, 10 patients with major renal trauma who operated by unified approach technique were included in this study. Blunt trauma was the mechanism of injury in 8 patients and 2 were resulted from penetrating(stab) injury. Of the injuries 2 were grade 3, 7 grade 4, 1 grade 5. RESULTS: Of the 10 patients, 8(80%) were performed kidney preserving surgery and 2(20%) resulted in nephrectomy. Partial nephrectomy was underwent in 6 patients(with vascular repair in 2 cases) and renorrhaphy in 2 patients. Pedicle flap of omentum was used mainly and polyglycolic acid mesh also used in 2 cases as coverage material of parenchymal defect. Complications occurred in 2 cases(20%) but none resulted in renal loss with the mean followup of 10 months(1 to 15 months). CONCLUSIONS: Unified approach technique of vascular control before renal exposure seems to be a safe and effective method for reconstructive surgery in renal trauma. To confirm this result, studies with more cases and longer followup are needed.

BACKGROUND: Oral allergy syndrome(OAS) is composed of it,ching sense and edema in oral cavity, lips, throat, pharynx, and larynx following eating some fresh fruits or vegetables. It has been known that most of patients with OAS are allergic to pollens. Common epitopes were found among pollens, fruits and vegetables. Although OAS is a common farm of food allergy in adults, this is the first epidemiologic study of OAS in Korea. MATERIAL AND METHOD: One hundred and fifty one patients who showed positive skin reaction to pollens were telephone-interviewed. Investigation of the prevalence and clinical manifestations of OAS was possible in 81 patients. RESULT: The prevalence of OAS among these patients was 34.6% (28/81). OAS was found in 24(48%) out of 50 patients sensitized to tree pollens, whereas 4(13%) of 31 grass or weed pollen-sensitized paients had OAS. Most common causative food was apple and all of 17 apple- OAS patients were sensitized to tree pollens. Peach was the second common food and 14 of 15 peach-OAS patients were sensitized to tree pollens. Besides oral symptoms, rhinitis, asthma, diarrhea, nausea, vomiting or generalized urticaria were accompanied in half of the OAS patients (14/28). Some patients showed OAS to some unique Korean foods such as dropwort, taro and Aster. CONCLUSION: OAS was very common in pollen-sensitized patients. Larger epidemiologic studies are needed to find unique Korean foods and their antigensm causing OAS.

BACKGROUND: Aside from its well known peripheral antihypertensive effects, calcium also lowers blood pressure, when administered into the cerebral ventricle. The present study was aimed to determine whether the central depressor response to calcium is mediated by a stimulation of endogenous L-arginine-nitric oxide (NO) pathway. METHODA: Mean arterial pressure (MAP) and heart rate (HR) were continuously recorded from the femoral artery in anesthetized rats. Administration of calcium was performed into the right lateral cerebral ventricle. The effects of N G-nitro-L-arginine methyl ester (L-NAME) on the cardiovascular response to calcium were examined. RESULTS: Intracerebroventricular (ICV) injection of calcium consistently produced a decrease in MAP and HR. The depressor and bradycardiac responses to calcium showed a dose-dependent fashion. Pretreatment with a calcium channel blocker, diltiazem (1 micromol, ICV), attenuated cardiovascular responses to calcium. ICV infusion (1 microl/min) of L-NAME (200 microgram/kg and 20 microgram/kg/min for 60 min) increased MAP without significant changes in HR. Chronic ingestion of L-NAME (5 mg/100 ml in drinking water, 4 weeks) also increased the systolic blood pressure as compared with control. The depressor effect of ICV calcium was significantly diminished in acute or chronic L-NAME treated rats. CONCLUSION: These findings suggest that the central depressor response to calcium, at least in part, is NO-dependent.

By implementing epoch-making policies of industrial promotion, the national economy has made a remarkable development. As a result of such economic growth, industrial accidents and occupational diseases have become a serious problem in Korean society. In the presidential order for the execution of the Korean labor standard law, neuritis and other diseases stemming from health impairments due to vibration in industrial processes are designated to be dealt with as vibration diseases. In the case of vibration disease, industrial accident compensation is not effectively paid. In order to investigate vibration hazards of rock-drill operators, the author studied subjective symptoms and did physical function tests on a total of 208 persons (vibration exposed group), who used rock-drills, and 115 persons (control group) who are not using rock-drills at anthracite mines. The results of physical function test are as follows. 1. There is no difference in smoking habits between the vibration exposure group and the control group. 2. In the use of their ear plugs, both the vibration exposed group and the control group showed a low tendency in using the ear plugs. 3. In the prevalence rate of white finger, the vibration exposed group reached 12.5 percent, but only 0.9 percent in the control group. Thus, both groups showed different rates in the initiation of their illness (p < 0.01). 4. The prevalence rate of finger numbness for the vibration exposed group was 23.1 percent, but only 9.6 percent in control group (p < 0.05). 5. In the prevalence rate of insomnia, the vibration exposed group had 22.6 percent and the control group 9.6 percent. Thus, the vibration exposure group showed a higher rate than the control group (p < 0.05). 6. In the vibration sense threshold, the vibration exposed group showed a statistically higher level than the control group (p < 0.01). 7. In the mean value of skin temperature, the control group was higher than the vibration exposed group (p < 0.05). 8. In the amount of perspiration, the exposed group measured higher than the control group (p < 0.01).

Emphysematous urinary tract infection is a rare, life-threatening necrotizing infection characterized by gas generation, and usually occurs in patients with diabetes and/or urinary tract obstruction. We herein report a unique case of emphysematous renal infection occurred in. an old diabetic man with renal cell carcinoma. This case suggests that renal cell carcinoma should be also considered a rare cause of emphysematous renal infection showing mass contour.

The authors conducted an in-Vivo experimental study using sciatic nerve of 200-300 grammed rats to verify clinical applicability of Silicone cuffing method, by which scar adhesion of repaired nerve in crushed limb is assumed hopefully to be reduced. The following observations were obtainable. 1. Nerve conduction velocity was noted faster in Silicone cuff group than in control group significantly after 6 weeks postoperatively. 2. Adhesion of repaired nerve with surrounding scar tissue was far less present in Silicone cuff group than in control group when observed grossly. 3. The amount of scar formation and axonal degeneration were noted reduced remarkably in Silicone cuff group than in control group after 3 weeks postoperatively. 4. The intraneural vascularity was noted reduced either in Silicone cuff group and in control group, but definitely less reduced in the former than in the latter. Clinical relevance: Above results may be taken as an experimental basis supporting clinical applicability of Silicone cuff wrapping method for neurorraphy in crushed limb.
