Lipodystrophia centrifugalis abdominalis infantilis, an typical form of progressive lipodystrophy, is a disease mainly decribed in japanese infants. We report a case of lipodystrophia centrifugalis abdominals infantilis in Korean infant. The patient is a 2 year-old-girl with a coin sized well defined depressed lesion with surrounding redness and scaly changes in the right inguinal region. The skin from the depressed lesion revealed changes similar to those originally described by Imamura et al.

Mutant p53 is associated with the advanced stages of some human tumor but there is a wide variation in the reported incidence of p53 mutation in renal cell carcinoma and its prognostic significances. We designed this study to assess the expression of p53 in renal cell carcinomas and to compare with the established prognostic factors. Immunoreactivity for p53 protein and proliferating cell nuclear antigen (PCNA) were assessed in 44 cases of primary renal cell carcinoma, and flow cytometric analysis of DNA ploidy was perfon-ned in 37 of those cases. p53 protein was over-expressed in 16/44 (36.4%) renal cell carcinomas and 5 rumors had more than 10 immunoreactive tumor cells. The expression of p53 protein was positively related to nuclear grade (p=0.007) and PCNA index (p=0.002), but was independent of stage and DNA ploidy. In univariate survival analysis, stage (p<0.001), nuclear grade (p=0.017), DNA ploidy (p=0.045) and PCNA index (p<0.001) were significantly associated with patient survival. However, considering the stage, all of the last three factors had no prognostic influence. Cases showing strong positivity of p53 expression had worse prognosis than those with no or weak p53 expression, especially in early lesions (stage I,II) (p<0.001).

Authors analyzed the findings of nineteen cases of arthroscopic second-look operations after posterior cruciate ligament (PCL) reconstruction with autogenous bone-patellar tendon-bone (BPTB) and Trevira augmentation by two tunnel technique during the period from Nov, 1993 to Jan. l997 in fifty-one cases, along with the results of reconstruction in terms of clinica1 knee scoring, radiographichl and arthroscopic findings. The results were as follows; Age ranged fmm 20 to 53 years, the average being 32.3 years. Thirteen cases (68%) had associated knee injuries; five medial collateral ligament (MCL) injuries, four lateral collateral ligament (LCL) injuries, two associated injuries of MCL and medial meniscus, one both menisci and one associated injury of anterior cruciate ligament and MCL. The average period fmm PCL injury to reconstruction was 7 weeks (range, 1 to 52 wecks) and the mean period from PCL reconstruction to second-look operation was 20.3 months (range, 10 to 46 months). The average Miiller s knee score at the last follow-up was 86 paints. The radiographical results: The distance of posterior translation of the PCL reconstrueted knee compared with the normal sidc knee in posterior stress roentgenography was average 3.8mm (range, 0 to 1 1 mm). The position of the fernoral bone block on the plane of extended Blumansaats line, from the anterior end of the line, was average 32%. The level of proximal end of the tibial bone block according to the tibial tunnel orifice into the joint was mean negative 2.6 degrees position. The findings of arthroscopic second-look examination; In 9 cases (47%), the reconstructed ligamcnts were well covered with synovial tissue and looked like almost normal PCL. There were five cases (26%) of severe fragmentation, three cases (16%) of partial torn fibers of the grafted tendon. And one case showed the thinning of thc grafted tendon compared with the initial diameter at the time of reconstruction and one case showed overgrawth of the synovial membrane which suitounding the grafted tendon. All the Trevira which were augmented at the time of PCL reconstruction were ruptured. Twelve cases (63%) were stable, three cases (16%) were slightly lax and 4 cases (21%) showed laxity of the grafted tendon by the posterior drawer test and probing under arthroscopy, The isometricity which was checked at the time of PCL reconstruction was average 3.4mm. From the ahove results, PCL reconstruction with autogenous BPTB by the two tunnel technique seemed to be a valuable procedure, but there were some cases of unfavorable results. Authors think that a new graft fixation method is needed for resolving the problem mentioned above.

Osteoporosis is a disease characterized by excessive bone loss or osteopenia particulary in the axial skeleton at the site of fracture, such as the spine and proximal femur. Since the strength of both spine and femur is directly proportional to the bone mass, this osteoporosis always increases the risk of fracture. In this study, to evaluate whether a simple measurement of femoral geometry and BMD value are related with hip fracture, we obtained DEXA Scan (Lunar Expert-XL) of hip by retrospective study. DEXA scan was measured on 70 control people and 17 hip fracture patients aged 50 or older. The result is I. The mean Ward BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.52g/cm2, Control group: 0.67g/cm2 P=0.0001) 2. The mean L-spine BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.81g/cm, Control group: 0.97g/cm2 P=0.0002) 3. The mean femur axis length of hip fracture group is longer than control group (Hip fracture group: 6.77g/cm2, Control group: 6.57g/cm2 P=0.006) As a conclusion, the measurement of BMD and hip axis length in DEXA scan is an effective method for screening the hip fracture risk patient and BMD value of femur, hip axis length and L- spine BMD value are strongly associated with hip fracture.

BACKGROUND: Acute hypoxia tolerance has been evaluated by the time of useful consciousness, subjective symptoms, cardiovascular changes, visual deterioration, psychological performance, and so forth. But these methods are either subjective, lacking strict objectivity, or too demanding to collect sufficient data. Pulse oximeter monitoring has come to be used not only in hospitals but in the aviation environment. This noninvasive oxygen monitoring apparatus warrants a highly objective analysis to investigate acute hypoxia tolerance. METHODS: Eight healthy male volunteers (20-25 years old) were exposed three times to a simulated altitude of 25,000 ft (7,620 m) at intervals of 7 days. We monitored arterial oxygen saturation (SaO2) and pulse rate by a pulse oximeter. The duration from taking the mask off to the time of 60% SaO2 was regarded as acute hypoxia tolerance. The venous hemoglobin concentration was measured a day before exposure to hypoxia. A questionnaire on the 14 subjective hypoxic symptoms was obtained after hypobaric chamber training. RESULTS: There were neither differences of acute hypoxia tolerance, hemoglobin concentration, nor pulse rate according to the repeated exposure of hypoxia. Four symptoms of sleepiness, fatigue, flushing and thinking impairment were sustained regardless of repeated exposures to hypoxia. But the incidence of symptoms of ear pain, anxiety, abdominal pain were reduced according to the repeated hypoxia. CONCLUSION: With pulse oximeter monitoring there was no difference between the values of time of 60% SaO2 in repeated exposures to hypoxia. The incidence of some subjective symptoms was reduced according to the repeated exposures to hypoxia.

PURPOSE: To investigate if the use of the infrared warm compression device often used in clinical settings induced heat shock proteins. METHODS: Subjects were heat-treated with an infrared warm compression device for 20 minutes. We examined the temperature of the upper eyelid and cornea before and after heat treatment and images were obtained by Digital Infrared Thermal Imaging System. After 6 hours of heat treatment, conjunctival epithelial cells were obtained by gently pressing nitrocellulose paper on the conjunctival surface for 3 to 5 seconds Immunocytochemical staining analysis was performed on the obtained samples. Tear samples were obtained prior to heat treatment and Western blot was performed to observe the expression patterns of heat shock proteins 27, 47, 70, and 90. RESULTS: By Western blot and immunocytochemical analysis, heat shock proteins 70 and 27 were significantly increased in the heat-treated samples. However, no difference was observed for heat shock proteins 47 and 90 before and after heat treatment, according to the immunocytochemical analysis. On Western blot, heat shock protein 47 was slightly increased by heat treatment but heat shock protein 90 did not show a significant difference after heat treatment. CONCLUSIONS: It was observed that the infrared warm compression device significantly increased the induction of heat shock proteins 27 and 70, and that 47 was also slightly induced. This result suggests that the device developed herein could be used as a new therapeutic modality for the reduction of inflammatory cell injury through the induction of heat shock proteins.
