We report a case of primary adenocarcinoma of the urethra in 62 years old female. Primary carcinoma of the female urethra is an uncommon malignancy that accounts for less than 0.02 per cent of all cancers occurring in women. Adenocarcinoma is rare in the literature. Whereas squamous cell carcinoma and transitional cell carcinoma, which comprise the majority of urethral malignancies, arise form the squamous or epithelial cells lining the urethra, adenocarcinoma arises form the periurethral glands.

PURPOSE: Conventional intravenous nutrition has been given as a solution of amino acids combined with dextrose and a separate line delivering a lipid emulsion. This technique was unsatisfactory, however, because of difficulties in managing technical and metabolic complications. Since the first clinical use of a single solution containing all the necessary nutrients was introduced in 1976, the total nutrient admixture (TNA) system has been used. However, despite the numerous advantages of this TNA system, it has not been used worldwide because of an assumption about unstability of this admixture. This study was conducted to compare the physical stability of TNA systems using two different 2 commercially available amino acid solutions and fat emulsions. METHODS: Each group contained 600 ml of 20% dextrose, 250 ml of 10% amino acid solution, 250 ml of 10% fat emulsion, 0.2 ml of heparin, and 20 ml of electrolyte solution was investigated for 7 days while being stored 4oC and at ambient temperature. The stabilities of these admixtures were compared by noting changes in macroscopic appearance, pH, osmolarity, Zeta-potential, peroxide value, particle size and distribution, and fat composition. RESULTS: When an amino acid solution containing P 2 was used, a supernatant yellow band was observed from the 3rd day at ambient temperature. The pH and peroxide value also showed significant changes, but these changes did not exceed the product-specifications. When an amino acid solution without P 2 was used, no significant change was observed. CONCLUSION: TNA systems are physically stable at 4oC temperature for at least 7 days, but TNA systems prepared with amino acid solution containing P 2 are not stable at ambient temperature from the 3rd day. On the other hand, TNA systems prepared with an amino acid solution without P 2 are stable at ambient temperature for 7 days. Various commercially available fat emulsions containing 10% soybean oil did not affect the stability of TNA systems.

BACKGROUND: We studied the incidence of trauma caused by alcohol related accidents, and the effects that has on the occurrence, the extent, and the outcome to the patient. METHODS: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of january 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were divided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analysed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. RESULTS: The total of the trauma patients, added up to 832 people, 577: male and 255: female. Among this sum, 16 trauma patients were alcohol related(male:127 & female 36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mossy by fast-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer alcohol-related trauma patients. CONCLUSION: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time it the reason for their visit were mossy because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.

OBJECTIVE: To determine whether ankle plantar flexors stretching exercise affects functional reach in elderly men. METHOD: Twenty elderly men with an average age of 78.2 years were selected for this study. A active range of motion of ankle dorsiflexion and a functional reach (FR) distance were measured before and after ankle stretching exercise. The ankle dorsiflexion was measured by goniometer in knee extended position. The FR distance was measured in standing position. Ankle plantar flexors stretching exercises were carried out by physical therapist 4 times per week for 4 weeks. At 4 weeks after the stretching exercise, we retested the active range of motion of ankle dorsiflexion and the FR distance using the same method. RESULTS: At 4 weeks after the stretching exercise, the active range of motion of right ankle dorsiflexion was increased from 2.81 +/- 3.26degrees to 5.98 +/- 4.34degrees, and the left ankle dorsiflexion was increased from 3.15 +/- 3.77degrees to 6.35 +/- 2.45degrees. The FR distance was increased form 12.22 +/- 7.54 cm to 19.69 +/- 8.59 cm after the stretching exercise. CONCLUSION: The FR distance was significantly increased after the ankle plantar flexors stretching exercise (p<0.01). This results suggest that the ankle plantar flexors stretching excercise may be capable of increasing the FR distance in elderly.

6.Effects of Muscle Fatigue on Knee Proprioception.
Journal of the Korean Academy of Rehabilitation Medicine 1998;22(4):960-965
OBJECTIVE: To determine whether muscle fatigue affects knee joint proprioception. METHOD: Thirty healthy subjects (18 male and 12 female) with an average age of 22.1 years were selected for this study. Angular errors were measured to test propriocetive function in the knee joint. In a sitting position, the subject's dominant leg was passively positioned to the 45degrees knee flexion stimulus point for 2~4 second, while the subject concentrated on this position, the leg was passively returned to the 90o flexion position, afterward the subject was asked to duplicate the stimulus point actively. The difference, in degrees between the stimulus point and the reproduced point is an angular error. All subjects were blindfolded and underwent proprioception measurement before and after the muscle fatigue. Isokinetic exercises performed at 180 degree/sec on the Cybex Orthotron II(Cybex, a division of Lumex, Inc. USA) were used to induce the muscle fatigue. All subjects performed an isokinetic exercise with their dominant leg. Exercise was continued until 50% of the initial peak torque was reached. When the subjects were fatigued to less than 50% of the initial peak torque, the isokinetic exercises were discontinued. Then we immediately retested the proprioception using the same method. RESULTS: The mean and standard deviation of the angular error increased from 2.79+/-1.17degrees to 6.40+/-3.42degrees after muscle fatigue. CONCLUSION: The proprioception significantly decreased after the muscle fatigue(p<0.001). This result suggests that the muscle fatigue must be considered when an injured professional athlete a patient with fatigable disease is set in a rehabilitation program. Further studies are required to determine the physiological mechanisms of the role of muscle fatigue for the decreasing proprioception.

To investigate the effect of hyperbaric oxygenation on superoxide dismutase activity, neonatal rats (7-10 days old) and adult rats (approximately 100 days old) were continuously exposed to hyperbaric oxygen environment of 2.4ATA for 8 hours and their superoxide dismutase activity were measured. Neonatal rats, all survived through exposure, showed significant increases in the pulmonary superoxide dismutase activity at immediately and 24 hours after exposure. Adult rats, whose 8 hour survival rates were 14 %, did not show any significant increase in the activity of pulmonary superoxide dismutase as compared to the control adult rats. These findings are indicating that increased tolerance to oxygen toxicity in neonatal animals during exposure may be attributed to the increase in activity of superoxide dismutase in neonatal rats.

A case of cryptococal hepatitis in a 4-year-old girl was presented with a brief review of the literature. She was admitted with the chief complaints of jaundice, abdominal pain, and semicomatose mental state. Treatment was started including dexamethasone under impression of fulminant hepatitis. During treatment massive G-I bleeding appeared which required eleven pints of blood and 20 days for control. Upper G-I series revealed duodenal ucer. And explolparotomy was performed because of free air in the peritoneum. Operative liver biopsy done at that time revealed many cryptococci in the biopsy tissue. Therefore we treated her with-5-fluorocytosine and the result was good. Follow-up of her for a year and half revealed that she was in here good general condition. Therefore we consider that secondary change in liver such as cirrhosis has not yet occurred in her.

BACKGROUND: A number of factors can cause dark circles around the eyes including excessive pigmentation, thin and translucent lower eyelid skin overlying the orbicularis oculi muscle, and shadowing due to skin laxity and tear trough. Autologous fat graft is an effective method for the treatment of lower lid dark circles, but irregularities caused by leaving visible lumps of the fat can occur. Tonnard et al. suggested 'nanofat' grafting and introduced its characteristics and clinical applications. The authors used their nanofat grafting to correct lower eyelid dark circles. METHODS: Nanofat grafting was performed in 19 patients for dark lower eyelids. The grafts were injected into subdermal layer using blunt cannula. Microfat grafting with nasojugal fold was performed to all the patients. Among them, 18 patients received transconjunctival fat removal at the same time. RESULTS: All the patients showed much improvement from preoperative dark coloration. There were no visible lumps of fat, contour irregularities, or fat necrosis. Postoperative edema and ecchymosis were minimal. CONCLUSIONS: Nanofat grafting methods provide a good alternative for correcting dark circles by augmenting thin skin with lower complications. This simple, cost effective procedure is suitable for correction of dark circles and various skin rejuvenation purposes.

Conjunctival aspergillosis refers to the infectious process of conjunctiva caused by one of the numerous members of the genus Aspergillus. A 4 year old Korean boy was brought to our hospital due to localized injection and edema of the left temporal bulbar conjunctiva which did not respond to the systemic and topical antibiotics for about 2 weeks. Clusters of the Aspergillus element was identified by the conjunctival biopsy and the diagnosis was made.
