Delayed diagnosis of the compartmental syndrome and subsequent delay in performing the fasciotomy can result in needless loss of function and possible amputation of the involved extremity. Unfortunately early evidence of this syndrome is difficult to assess. A direct measurement of the tissue pressure within a closed compartment has been developed which provides physicians with reliable information for determining the need for fasciotomy. In the 27 cases of the tibia fracture, tissue pressure was measured directly by method of the needle manometer in the Department of Orthopedic Surgery, Han Kang Sung Sim Hospital from March, 1979 to August, 1979. The results were as follows: 1. The highest mean tissue pressure per hour was 28 mmHg in anterior compartment at 24 hours after trauma, and 28.4 mmHg in deep post compartment at the same hours. 2. The highest pressure measured in all cases was 38 mmHg in anterior compartment at 24 hours and 39 mmHg in deep posterior compartment at 48 hours after trauma. 3. The return of increased tissue pressure to less than 10 mmHg took 122.6 hours in anterior and 124.4 hours in deep posterior compartment. 4. Tissue pressre was higher when there was associated fibula fracture. 5. Tissue pressure was higher in displaced fractures than in undisplaced fractures. 6. Tissue pressure was higher when fracture was in its upper one-third. 7. Tissue pressure was higher in comminuted fracture than simple fracture.

Neoadjuvant concurrent chemoradiotherapy has been increasingly used to obtain secondary resectability for locally advanced pancreatic cancers. Although most patients require biliary decompression, only a few studies have investigated the safety of biliary stenting with chemoradiotherapy. Herein, we report a rare case of delayed hemorrhage of the hepatic artery caused by biliary stenting after chemoradiotherapy. The serial follow-up CT demonstrated that the biliary stent was approaching the right hepatic artery and eventually caused acute angulation and indentation. Diagnostic catheter angiography revealed contrast extravasation at the right hepatic artery, and endovascular embolization was performed. This report highlights the relevance of anatomical deformation after chemoradiotherapy, which can result in fatal complications. Indentation of the hepatic artery caused by biliary stents should be recognized as a warning sign of vascular injury.

BACKGROUND: Clinically apparent thyroid nodule is a very common disease in adults. Patients are often treated with thyroxine in order to reduce the size of the nodule, but the efficacy of thyroxine-suppressive therapy with thyroxine remains uncertain. We investigated the efficacy of thyroxine-suppressive therapy and the hormonal characteristics during thyroxine therapy to find out whether such measurement could be used to determine the effectiveness of this therapy in patients with benign solitary thyroid nodule proved by aspiration biopsy. METHODS: In this study, 54 patients were randomly assigned to receive L-thyroxine (Group I, n=24) or placebo (GroupII, n=30) for 1 year. High resolution ultrasonography (10MHz) was used to measure the size of the nodules at six month intervals. Thyroid hormones and thyroglobulin assay and FNA (fine needle aspiration) was done at the same time. The dose of thyroxine was 200ug/day. Patients were followed at 6 month intervals. RESULTS: The results were as follows: 1) 13 (54.1%) out of 24 Group I patients after adequate TSH suppression had a statistically significant reduction of nodule size and before-to-after nodule volume ratios were significantly different between the Group I and Group II patients. 2) In the responders among Group I patients, the before-to-after therapy ratio of the nodule volume was not related to the pretreatment nodule size, thyroid hormones and thyroglobulin levels. CONCLUSION: Thus we concluded that an adequate suppressive dose of L-thyroxine significantly altered the volume of the benign solitary thyroid nodules 12 months later.

Ruptures of extensor pollicis longus tendon after distal radial fractures are well-known. However, delayed flexor tendon rupture of finger as a complication of the fracture are less common. We report the case of delayed rupture of flexor digitorum profundus tendon to middle and ring fingers and flexor digitorum superficialis to ring finger in 72 year old female patient. She was treated by free tendon graft with palmaris longus tendon. After 1 year follow-up, range of motion and flexion power were recovered to nearly normal.

We performed the same day dipyridamole stress/rest myocardial SPECT in 14 healthy young men, reconstructed the polar maps according to Cedars-Sinal method and quantitated the radioactivity of myocardial wall. We divided the whole myocardium to 9 sectors. The latero-anterior wall contains the highest count. The infero-septal wall contains the lowest count. There isn't any significant differences of radioactivity in each segment between stress and rest polar map. The hemodynamic parameters after dipyridamole injection in the subjects were significantly changed except systolic blood pressure : the heart rate was increased and diastolic blood pressure was decreased. Adverse effects were reported in 85.7%. We suggest that these data can be used to dectect perfusion defect in the coromary artery disease.

Many previously described nuclear medicine procedures to assess glomerular filtration rate have some problems because numerous blood sample is to be taken and they don't measure each separate renal function. Gates described isotopic method for the measurement of global and unilateral GFR based on the fractional renal uptake of (99m)Tc-DTPA 2 to 3 minutes after its intravenous injection. We evaluated GFR using (99m)Tc-DTPA in 57 people according to Gates method and compared with creatinine clearance. A good correlation was observed between creatinine clearance and GRF calculated by Gates' formula with an r value of 0.9(P<0.05). And also the relationship between parameters of (99m)Tc-DTPA renal scan images and GFR was taken. They were significantly correlated with GFR calculated by Gates' formula : r value 0.66 between relative intensity of peak renal to peak aortic activity(pK/pA) and GFR, -0.42 between time between aortic and kidney peak(A-K) and GFR and -0.48 between parenchymal renal activity at 25 min compared to peak kidney activity(25K/pK) and GRF. In conclusion, the determination of GFR according to Gates' formula shows good and reproducible of GRF with rapidity and simplicity. And the parameters from the renal scan images can use to estimate the renal function.
