Subtalar dislocation of the foot is one in which there is simultaneous dislocation of the talonavicular joint and talocalcaneal joint while the tibiotalar relationship is unchanged. It was described first by Judey and Defourest in 1811. It incidence was 1% to 1.3% of all dislocations and 15% of injuries of the talus. We have experienced one case of a medial subtalar dislocation without fracture. In our case which was followed for 14 months, the head of the talus was palpable on the dorsum of the foot and the heel was displaced medially in relation to the leg. Radiographically, on the lateral view, the head of the talus was shown superior to the navicular and on the A-P view, the normal talonavicular relationship was disturbed with the calcaneus being displaced medially. The closed reduction was carried out successfully.

BACKGROUND: This study was performed in order to investigate the changes of Na+ transport system in the red blood cells of patients with essential hypertension. METHODS: Na(+)-Li(+) countertransport and Na(+)-K(+) pump activity were measured in 30 cases of essential hypertension and 20 healthy normal controls. And these measurements were analyzed in terms of some important clinical parameters in the patients, i.e., body mass index(BMI), status of hypertension and plasma lipids. RESULTS: Na(+) and K(+) contents of red cells in hypertensive patients were 16.9+/-1.4 and 77.8+/-2.1mmol/L cells, respectively, and no significant difference was found compared with respective value of normal control(14.2+/-0.9 and 82.2+/-2.8mmol/L cells). Na(+)-Li(+) countertransport in the patients group was significantly ancreased compared with control group(62.5+/-4.5 and 46.8+/-3.0umol/L cells.hr), and Na(+)-K(+) pump activity was also showed a significant depression(8.72+/-0.80 and 12.79+/-0.52umol Pi/mg.hr). In the analysis regarding the relationship between Na(+) transport system and some important clinical parameters of the patients with essential hypertension, Na(+)-Li(+) countertransport was related to BMI, and the level of triglyceride. On the other hand, Na(+)-K(+) pump activity was related to the WHO stage and the levels of total cholesterol and triglyceride. But level of blood pressure did not show a significant correlation with either are of the two Na(+) transport system. CONCLUSION: These resluts suggest that Na(+)-Li(+) countertransport and Na(+)-K(+) pump activity in patients with essential hypertension were significantly altered compared with heathy normal controls, and these Na(+) transport system were also influenced by BMI, WHO stage, and the levels of cholesterol and triglyceride. And the individual variation in Na(+) transport system were also suggested by the findings being overlapped between hypertensive patients and controls.

Due to the great deal of effort that has gone into the study of osteoclastic differentiation and activation over the last few decades, the mechanisms of these two events have been discovered gradually. Nitric oxide(NO-), which is produced from arginine by a nitric oxide synthase, opened up a new area of biological research. Recently, it has been reported that NO- is produced by osteoblasts stimulated by lipopolysaccharide and several other cytokines. In this study, the effect of sodium nitroprusside(SNP), a donor of nitric oxide(NO-), on osteoclast-like cell formation and on mature osteoclast function was examined. To determine the mechanism of the inhibitory effects of SNP decreased not only the basal 45Ca release but also thee bone resorption induced by PTH and l,25-dihydroxyvitamin D3 (I ,25[OH]2D3). The inhibitory effect of SNP on bone resorption induced by PTH appeared 2 days after treatment, whereas SNP effect on inhibiting bone resorption induced by l,25[OH]2D3 appeared at the third days. When chicken and rat osteoclasts were cultured on dentin slices, treatment of 300micronM SNP resulted in a significant decrease in dentin resorption by osteoclasts in terms of total resorption area and average individual area. We also examined the effect of SNP on formation of osteoclast-like cells that is TRAP-positive multinucleated cells from chicken and rat bone marrow cells in the presence or absence of 10(-8)M l,25[OH]2D3. The addition of 300 micronM SNP inhibited the formation of TRAP-positive multinucleated cells. The present data suggest that SNP, possibly as a NO- donor, inhibits the osteoclastic differentiation and osteoclastic activity.

A retrospective study was made of the previous medical records of 47 infants with congenital syphilis born from mothers with untreated syphilis at Severance Hospital, Yonsei University College of Medicine during the years 1972 through 1983 The VDRL titer of these infants was higher than 1: 8 with reactive FT.A-ABS test. They were subjectd to hematologic examinations and the results were as follow s, 1. Of 46 infants with congenital syphilis, anemia was observed in thirty-one (68%) Reticulocytosis occurred in seventeen(89%) of nineteen infants with congenital syphilis having the mean value of 6. 0%. 3, Of 4.7 infants with congenital syphilis, leucocytosis was noted in seveenteen 4, Thrombocytopenia was observed in twenty (64%) of thirty-one infants with congenital syphilis.
