Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in synovial membrane, periarticular structure, skeletal muscle and perineural sheaths. Eventually, joints are destroied, ankylosed and deformed. Moderate anemia is occured frequently in rheumatoid arthritis patients, and these patients show abnormalities of iron metabolism such as lower serum iron concentration and occurance and distribution of iron in the synovial membrane. It has been suggested that the mechanism of iron deposits in rheumatoid arthritis is continuous oozing of blood from vascular granulation tissue into the synovial cavity and this lead the patient to anemia. We collected samples from serum and knee joint fluid in 21 cases of rheumatoid arthritis for chemical estimation of the ferritin concentration by radioimmunoassay, and compared with that of osteoarthritis. The following results were obtained: 1. The mean hemoglobin concentration(11.4gm %) in rheumatoid arthritis was lower than osteoarthritis(13.4gm %). 2. The mean serum ferritin concentration(118. 4ng/ml) in rheumatoid arthritis was lower than osteoarthritis(135. 6ng/ml), on the contrary in synovial fluid rheumatoid arthritis(279.8ng/ml) showed higher than osteoarthritis(190. 4ng/ml). 3. The mean ratio of synovial fluid ferritin on serum ferritin was 2. 36 in rheumatoid arthritis, in contrast with l. 4 in osteoarthritis. There was significant correlation between the ferritin concentration in synovial fluid and serum. 4. Serial check of ferritin concentration in synovial fluid during treatment would be thought meaningful criteria for determination of progress.and effectiveness of treatment.

Synovial sarcoma is an uncommon, highly malignant soft tissue tumor usually arising from the synovial lining of a joint, bursa and tendon sheath. Occurence in muscle fascia is extremely rare. We present a case of synovial sarcoma of the left calf muscle fascia, which was confirmed by microscopically sarcomatous growth of spindle cells and irregular small multiloculation. Above knee amputation was done.

The head injuried patient with skeletal trauma is a challege to the orthopedic surgeon. The orthopedist initially may face the difficult management of fracture and dislocation in the patient associated with head injury. The management of the injuries to the head takes precedence over extremity injuries initially, but the orthopedist must be managed aggresively with assumption that full neurologic recovery will occur. This report analysed the treatment and results in 85 cases fracture and dislocation with head injury among the 59 patients at the Chungnam National University Hospital during the period ranging from March, 1980 to March, 1983. End result obtained are as follows: 1. The sex ratio between the male and female was 3.9: 1 and the prevalent age distribution was from 21 to 30 years of age. 2. The motorcycle accident was most common cause of the trauma and the next most frequent one was the automobile accident. 3. Type of head injury were contusion or concussion, intracranial hemorrhage, linear skull fracture, depressed skull fracture and open skull fracture. 4. Better result were obtained by operative treatment in femur fracture, especially spastic group. 5. The incidence of delayed diagnosis was 8 cases and the delay in diagnosis ranged from 15 to 95 days with an average of 38 days. 6. We, consulting with neurosurgeon, must assume that full neurologic recovery will take place and so open reduction and internal fixation should be carried out as quickly as possible.

We present a case of acquired tracheoesophageal fistula (TEF) which was found during induction of general anesthesia for clipping of aneurysm. The patient had been intubated with endotracheal tube for 10 days and then done tracheotomy for 45 days. Thereafter, TEF was confirmed by MRI and treated with fistula repair and tracheal fenestration. Acquired TEF can occur under the condition of prolonged tracheal intubation with high cuff pressure (>30 mmHg) and can also result from intratracheal neoplasm, mediastinitis, and other tracheal or esophageal damages. If unrecognized during anesthetic induction, TEF can cause gastric dilatation and rupture, pulmonary aspiration and respiratory failure. So early diagnosis and proper management is very important whenever TEF is suspected during anesthetic induction.

There is increasing need for network connecting personal computers(PC) together. Thus Local Area Network(LAN) emerged, which was designed to allow multiple computers to access and share multiple files and programs and expensive peripheral devices and to communicate with each user. We built PC-LAN in our department that consisted of 1) hardware-9 sets of personal computers(IBM compatible 80386 DX, 1 set:80286 AT, 8sets) and cables and network interface cards (Ethernet compatible, 16bits) that connected PC and peripheral devices 2) software - network operating system and database management system. We managed this network for 6 months. The benefits of PC-LAN were 1) multiuser (share multiple files and programs, peripheral devices) 2) real time data processing 3) excellent expandibility and flexibility, compatibility, easy connectivity 4) single cable for networking ) rapid data transmission 6) simple and easy installation and management 7) using conventional PC's software running under DOS(Disk Operating System) without transformation 8) low networking cost. In conclusion, PC-LAN provides an easier and more effective way to manage multiuser database system needed at hospital departments instead of more expensive and complex network of minicomputer or mainframe.

Recently we have experienced a cases of commotio retinae following traffic accident which accompanies with the triad of hypotony, myopia and mydriasis. Regarding to the importance of increasing traffic accidents, we report the above mentioned case with the review of literatures.

The effect of labetalol on induced hypotension was studied in 13 patients undergoing major spine surgery. Hypotension was induced with initial dose of labetalol 0.4 mg/kg i.v. followed by 0.01 mg/kg/min i.v.infusion. BP, HR, and CVP were measured before, during, and after hypotension. Anesthesia was maintained with isoflurane (0.5-2 vol%) and N2O in 50% O2 supplemented by pancuronium. The time to systolic BP 75-85 mmHg or mean BP 55-65 mmHg was 18.5+/-2.8min and the time for systolic BP to recover 90% of prehypotensive value was 45.5+/-4.2 min. Heart rate was reduced signiTicantly after hypotension but remained stable at 80-90 beats/min thereafter. Central venous pressure showed no significant change irrespective of hypotension. The results suggest that combined use of fentanyl with labetalol or disuse of pancumnium may reduce the required dose of labetalol.
